ABSTRACT

OBJECTIVE@#To report the clinical characteristics and treatment analysis of 3 cases of congenital ulnar collateral flexor contracture of the forearm and take a reference for clinic.@*METHODS@#A total of 3 patients with congenital ulnar collateral flexor contracture of the forearm were admitted between February 2019 and August 2021. Two patients were male and 1 was female, and their ages were 16, 20, and 16 years, respectively. The disease durations were 8, 20, and 15 years, respectively. They all presented with flexion deformity of the proximal and distal interphalangeal joints of the middle, ring, and little fingers in the neutral or extended wrist position, and the deformity worsened in the extended wrist position. The total action motion (TAM) scores of 3 patients were 1 and the gradings were poor. The Carroll's hand function evaluation scores were 48, 55, and 57, and the grip strength indexes were 72.8, 78.4, and 30.5. Preoperative CT of case 2 showed a bony protrusion of the flexor digitorum profundus tendon at the proximal end of the ulna; and MRI of case 3 showed that the ulnar flexor digitorum profundus presented as a uniform cord. After diagnosis, all patients were treated with operation to release the denatured tendon, and functional exercise was started early after operation.@*RESULTS@#The incisions of 3 patients healed by first intention. Three patients were followed up for 12, 35, and 12 months, respectively. The hand function and the movement range of the joints significantly improved, but the grip strength did not significantly improve. At last follow-up, TAM scores were 3, 4, and 4, respectively, among which 2 cases were excellent and 1 case was good. Carroll's hand function evaluation scores were 95, 90, and 94, and the grip strength indexes were 73.5, 81.3, and 34.2, respectively.@*CONCLUSION@#Congenital ulnar collateral flexor contracture is a rare clinical disease that should be distinguished from ischemic muscle contracture. The location of the contracture should be identified and appropriate surgical timing should be selected for surgical release. Active postoperative rehabilitation and functional exercise can achieve good hand function.

ABSTRACT

OBJECTIVE@#To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears.@*METHODS@#A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%).@*CONCLUSION@#Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.

ABSTRACT

A sobrevivência ao câncer de mama é um problema de saúde pública que demanda serviços especializados com foco na reabilitação psicossocial. Entre as necessidades identificadas nesse contexto está o incentivo à adoção de estratégias de promoção de autocuidados pelas mulheres. Uma das estratégias adotadas consiste no grupo de apoio psicológico, que auxilia as pacientes a enfrentar a longa jornada do tratamento. Assim, o objetivo deste estudo é compreender os significados produzidos por mulheres com câncer de mama sobre sua participação em um grupo de apoio. Trata-se de um estudo qualitativo, descritivo e exploratório realizado com dez mulheres com câncer de mama usuárias de um serviço de reabilitação para mastectomizadas. Como referencial metodológico foi utilizada a Teoria Fundamentada nos Dados. A coleta de dados foi realizada por meio de entrevista aberta em profundidade e os conteúdos foram transcritos e codificados. A análise indutiva e o método de comparação constante foram aplicados nos processos de codificação aberta, axial e seletiva, que permitiram identificar três categorias nucleares: percepção das atividades realizadas no grupo, identificação de benefícios e barreiras do convívio no grupo e transformações decorrentes da participação. As participantes significaram sua presença no grupo como fonte de acolhimento, apoio, desenvolvimento de recursos pessoais e amizades, contribuindo para promover sua qualidade de sobrevida. Além dos potenciais benefícios, também foram identificadas barreiras que podem dificultar a adesão e continuidade da participação no grupo, o que sugere a necessidade de incorporar no cuidado um olhar para as dimensões subjetivas da saúde da mulher.(AU)


Surviving breast cancer is a public health problem and depends on services focused on psychosocial rehabilitation. Healthcare providers must encourage women to adopt strategies to promote their self-care. The psychological support group is a resource that helps women to face the long journey of treatment. This study aimed to understand the meanings women with breast cancer produced about their participation in a support group. This exploratory cross-sectional study was carried out with 10 women with breast cancer who use a rehabilitation service for mastectomized patients. Grounded Theory was used as a methodological reference. An open in-depth interview was applied for data collection. The contents were transcribed and coded. Inductive analysis and the constant comparison method were applied in the open, axial, and selective coding processes, which enabled the identification of three core categories: perception of the activities carried out in the group, identification of benefits and barriers of living in the group, and transformations resulting from participation. Participants denote their involvement with the group as a source of shelter, support, development of personal resources and friendships that helps promoting quality of life. Besides these potential benefits, participants also evinced barriers that can hinder adherence and continuity of participation in the group, suggesting the importance of incorporating a look at the subjective dimensions of women's health into care.(AU)

ABSTRACT

Introducción: el músculo pronador cuadrado funciona como un estabilizador dinámico de la articulación radiocubital distal. Su reparación posterior a la fijación interna con placa de bloqueo volar en fracturas distales del radio es controvertida. Objetivo: determinar si la reparación del músculo pronador cuadrado influye en los resultados clínicos y funcionales de pacientes con fractura de radio distal que se sometieron a reducción abierta y fijación interna con placa de bloqueo volar. Materiales y métodos: se realizó una revisión sistemática y metanálisis. Las bases de datos analizadas fueron PubMed/Medline, Embase y Bireme/Lilacs (búsqueda realizada hasta el 20 de febrero del año 2023). Los términos de búsqueda fueron: distal radius fracture AND volar plate AND pronator quadratus. Se determinó la calidad metodológica según el manual de revisiones Cochrane. Resultados: en total se incluyeron 4 ensayos clínicos aleatorizados de adecuada calidad metodológica, lo cual corresponde al análisis de 213 participantes. Existen mejores resultados en la puntuación DASH a los 12 meses de seguimiento en el grupo de no reparación del músculo pronador cuadrado DM 2,8 [IC 95%: 0,51;5,10]. No hubo diferencias significativas al año de seguimiento en las puntuaciones de dolor, rangos de movilidad de la muñeca, fuerza de agarre e incidencia de complicaciones. Conclusión: no existe evidencia que sustente la reparación rutinaria del músculo pronador cuadrado posterior a la fijación interna con placa de bloqueo volar en las fracturas de radio distal. (AU)


Introduction: the pronator quadratus muscle functions as a dynamic stabilizer of the distal radioulnar joint, and its repair after internal fixation with volar locking plate in distal radius fractures is controversial. Objective: to determine whether the repair of the pronator quadratus muscle influences the clinical and functional outcomes of patients with distal radius fracture who underwent open reduction and internal fixation with volar locking plate. Materials and methods: a systematic review and meta-analysis were conducted. The analyzed databases were Pubmed/Medline, Embase, and Bireme/Lilacs (search performed until February 20th, 2023). The search terms were distal radius fracture AND volar plate AND pronator quadratus. Methodological quality was determined according to the Cochrane Reviewer's Handbook. Results: a total of 4 randomized clinical trials of adequate methodological quality, corresponding to the analysis of 213 participants, were included. Better DASH scores were observed at 12 months of follow-up in the non-repair group of the pronator quadratus muscle, with a mean difference of 2.8 [95% CI 0.51; 5.10]. There were no significant differences at one-year follow-up in pain scores, wrist mobility ranges, grip strength, and incidence of complications. Conclusion: there is no evidence to support routine repair of the pronator quadratus muscle after internal fixation with volar locking plate in distal radius fractures. (AU)

ABSTRACT

Abstract Objective To evaluate the incidence of symptomatic cyclops lesions requiring surgical treatment after anterior cruciate ligament (ACL) reconstruction and to establish possible intraoperative risk factors related to it. Methods Three hundred and eighty-nine patients aged between 18 and 50 years who underwent primary ACL reconstruction were retrospectively evaluated. Patients were divided into groups according to the presence or absence of symptomatic cyclops lesions, and their characteristics were compared. Patients with associated lesions that required additional surgical procedures (except anterolateral extra-articular procedures) were not included. The rate of symptomatic cyclops lesions was recorded and the following parameters were evaluated: age, gender, time from injury to surgery, graft type and diameter, femoral tunnel perforation technique, fixation type, presence of knee hyperextension, preservation of the ACL remnant, associated anterolateral extra-articular procedure, associated meniscal injury and participation in sports. Results 389 patients were evaluated and 26 (6.7%) patients developed cyclops. The patients with and without cyclops lesions did not differ in age, time from injury to surgery, graft type or diameter, surgical technique, femoral fixation method, presence of knee hyperextension, remnant preservation and associated meniscal injury. The group with cyclops lesion had a higher proportion of females (10 (38.4%) vs 68 (18.7%); OR = 2.7; p= 0.015), higher proportion of extra-articular reconstruction (18 (11.8%) vs 8 (3.4%); OR = 3.8; p= 0.001) and higher proportion of sports practice (23 (8.6%) vs 3 (2.5%); OR = 3.6; p= 0.026). Conclusion In our series, 6.7% of the patients required arthroscopic removal of cyclops lesions. Female gender, associated extra-articular reconstruction and sports practice were factors related to this lesion. Remnant preservation had no relationship with cyclops lesion formation.


Resumo Objetivo Avaliar a incidência de lesões cyclops sintomáticas que precisam de tratamento cirúrgico após a reconstrução do ligamento cruzado anterior (LCA) e estabelecer os possíveis fatores de risco intraoperatórios relacionados a elas. Métodos Trezentos e oitenta e nove pacientes com idades entre 18 e 50 anos submetidos à reconstrução primária do LCA foram avaliados de forma retrospectiva. Os pacientes foram divididos em grupos de acordo com a presença ou ausência de lesões cyclops sintomáticas e suas características foram comparadas. Não foram incluídos pacientes com lesões associadas que necessitassem de outros procedimentos cirúrgicos (à exceção de procedimentos extra-articulares ântero-laterais). A taxa de lesões cyclops sintomáticas foi registrada e os seguintes parâmetros foram avaliados: idade, sexo, tempo da lesão à cirurgia, tipo e diâmetro do enxerto, técnica de perfuração do túnel femoral, tipo de fixação, presença de hiperextensão do joelho, preservação do LCA remanescente, associação a procedimento extra-articular ântero-lateral, lesão de menisco associada e participação em esportes. Resultados Dos 389 pacientes avaliados, 26 (6,7%) desenvolveram lesão cyclops. Os pacientes com e sem lesão cyclops não diferiram quanto à idade, tempo da lesão à cirurgia, tipo ou diâmetro do enxerto, técnica cirúrgica, método de fixação femoral, presença de hiperextensão do joelho, preservação do LCA remanescente e lesão de menisco associada. O grupo com lesão cyclops apresentou mais mulheres (10 [38,4%] vs. 68 [18,7%]; razão de probabilidades [OR] = 2,7; p= 0,015), maior proporção de reconstrução extra-articular (18 [11,8%] vs. 8 [3,4 %]; OR = 3,8; p= 0,001) e maior proporção de prática esportiva (23 [8,6%] vs. 3 [2,5%]; OR = 3,6; p= 0,026). Conclusão Em nossa série, 6,7% dos pacientes necessitaram de remoção artroscópica das lesões cyclops. O sexo feminino, a reconstrução extra-articular associada e a prática esportiva foram fatores relacionados a essa lesão. A preservação do menisco remanescente não foi associada à formação de lesões cyclops.

ABSTRACT

Contexto e objetivo: Diversos benefícios são advindos da prática da atividade física durante o envelhecimento, porém poucos são os achados que apresentem os dados ao longo do tempo. Assim, o objetivo deste estudo foi verificar a estabilidade das variáveis da aptidão física e capacidade funcional de mulheres adultas praticantes de atividade física em um período de 10 anos. Desenho e local: Estudo longitudinal com mulheres de São Caetano do Sul. Métodos: A amostra foi composta por 157 mulheres com idade entre 45 e 86 anos (65,7 ± 6,7), analisadas em quatro intervalos de tempo: baseline, 6, 8 e 10 anos, todas praticantes de atividade física. A avaliação incluiu variáveis antropométricas, neuromotoras e de capacidade funcional. A análise estatística utilizada foi o teste t de Student, correlação de Spearman Rho e delta percentual. O nível de significância adotado foi de P < 0,01. Resultados: Os resultados apresentaram correlações de estabilidade alta e significante (rho = 0,64 a 0,87) nos três grupos nas variáveis índice de massa corporal, adiposidade, força de membros superiores, flexibilidade e agilidade. O acompanhamento de 6 a 10 anos evidenciou diferenças significantes de força de membros superiores, inferiores, agilidade e equilíbrio, sendo expressa pela redução da força de membros superiores de 8% a 13%, força de membros inferiores de 18% a 21%, agilidade de 18% a 19% e equilíbrio de 28% a 34%. Conclusão: Houve estabilidade das variáveis antropométricas, neuromotoras, capacidade funcional e equilíbrio de mulheres adultas praticantes de atividade física, mesmo apresentando redução significativa nas variáveis citadas anteriormente.

ABSTRACT

OBJECTIVE@#To explore clinical effect of arthroscopy-assisted rotator cuff tendon transfer in treating irreparable rotator cuff tears (IRCT).@*METHODS@#From May 2015 to May 2018, 23 patients with unrepairable rotator cuff tears were treated with arthroscopy-assisted rotator cuff tendon transfer, and 21 patients were followed up finally, including 8 males and 13 females, aged from 48 to 82 years old with an average of(64.3±9.1) years old;the courses of disease ranged from 6 to 36 months with an average of (14.0±6.4) months. American Rotator and Elbow Surgeons Score(ASES) and Constant-Murley score were used to evaluate clinical efficacy before surgery and at the latest follow-up.@*RESULTS@#All 21 patients were followed up for 36 to 54 months with an average of (39.4±4.4) months. Axillary incision of 1 patient was redness, swelling and exudation after surgery, which healed after 3 weeks of dressing change, and exudate culture was negative. At the latest follow-up, MRI showed partial tearing of the metastatic tendon in 2 patients, but pain and movement of the affected shoulder were still better than before surgery. ASES increased from preoperative (41.0±9.6) scores to the latest follow-up (75.6±14.0) scores, and had statistical difference (t=10.50, P<0.01). Constant-Murley score increased from (49.8±7.1) scores before operation to (67.5±11.6) scores at the latest follow-up (t=11.27, P<0.01).@*CONCLUSION@#Arthroscopic assisted latissimus dorsalis tendon transposition restores physiological and anatomical structure of glenohumeral joint by reconstructing balance of horizontal and vertical couples of shoulder joint, thus achieving the stability of the shoulder joint, relieving shoulder pain and improving shoulder joint function.

ABSTRACT

OBJECTIVE@#To investigate early effectiveness of arthroscopic superior fulcrum reconstruction in the treatment of irreparable massive rotator cuff tear (IMRCT).@*METHODS@#A retrospective analysis was conducted on the clinical data of 24 patients with IMRCT who met the inclusion criteria between January 2020 and April 2022. Among them, there were 11 males and 13 females with an average age of 56.2 years (range, 42-68 years). There were 12 cases of falling injuries, 3 cases of traction injuries, and the other 9 cases had no obvious causes. The disease duration ranged from 1 to 25 months (median, 6 months). The rotator cuff tears were classified as Hamada grade 2 in 18 cases and grade 3 in 6 cases, and Goutallier grade 1 in 3 cases, grade 2 in 20 cases, and grade 3 in 1 case. All patients were treated with arthroscopic superior fulcrum reconstruction. Visual analogue scale (VAS) score, Constant-Murley score, the University of California at Los Angeles (UCLA) score, and the American Shoulder and Elbow Surgeons (ASES) score were recorded before operation and at 1, 3, 6, and 12 months after operation.@*RESULTS@#The operations were all successfully completed. The incisions healed by first intention and no related complications occurred. All patients were followed up 12-33 months (mean, 24.6 months). The VAS, Constant-Murley, UCLA, and ASES scores at different time points after operation were superior to those before operation ( P<0.05). All of the above indicators further improved with time. Except for no significant difference in VAS and Constant-Murley scores between 6 and 12 months ( P>0.05), the differences between the other time points were significant ( P<0.05). At 12 months after operation, according to UCLA scoring standard, shoulder joint function was rated as excellent in 4 cases, good in 19 cases, and poor in 1 case, with an excellent and good rate of 96.0%. MRI showed that there was no graft re-tear and the transplanted tendon and bone tunnel healed.@*CONCLUSION@#The arthroscopic superior fulcrum reconstruction for IMRCT can effectively relieve the pain, improve the shoulder range of motion, and restore good shoulder function.

ABSTRACT

OBJECTIVE@#To investigate the early effectiveness of arthroscopic repair of supraspinatus tendon tears with douple-pulley suture-bridge.@*METHODS@#The clinical data of 38 patients with supraspinatus tendon tears who met the selection criteria between September 2020 and July 2022 were retrospectively analyzed, and all of them were treated with arthroscopic double-pulley suture-bridge technique. There were 15 males and 23 females, aged from 43 to 77 years, with an average of 61.5 years. There were 15 cases of left shoulder and 23 cases of right shoulder. Seven cases had a history of trauma, and the other 31 cases had no obvious inducement. The main clinical symptoms of the patient were pain in lifting the shoulder joint and hug resistance test (+). The time from onset of symptoms to admission ranged from 6 to 19 months, with an average of 10.3 months. Flexion, abduction, and external rotation of the shoulder were recorded before operation and at 3 and 12 months after operation. Pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, and American Society of Shoulder and Elbow Surgeons (ASES) score before operation and at 12 months after operation. Tendon healing, tendon continuity, and tension were evaluated by MRI at 3-6 months after operation, and patient's satisfaction was evaluated at last follow-up.@*RESULTS@#All the incisions healed by first intention, and there was no complication such as incision infection or nerve injury. All patients were followed up 12-34 months, with an average of 23.3 months. VAS score, UCLA shoulder score, and ASES score at 12 months after operation were significantly better than those before operation ( P<0.05). The external rotation range of shoulder joint significantly improved at 3 and 12 months after operation ( P<0.05), and it further improved at 12 months after operation when compared with 3 months after operation ( P<0.05). There was no significant difference in the range of flexion and abduction at 3 months after operation when compared with those before operation ( P>0.05), but the range of flexion and abduction at 12 months after operation significantly improved when compared with those before operation and at 3 months after operation ( P<0.05). MRI reexamination was performed in 28 patients at 3-6 months after operation. Among them, 25 patients had intact supraspinatus tendon structure, good tension, and tendon healing, and 3 patients had type 1 retear. The remaining 10 patients refused to undergo MRI reexamination because of the satisfactory effectiveness. At last follow-up, 29 patients (76.3%) were very satisfied with the results, 6 (15.7%) were satisfied, and 3 (7.8%) were not satisfied.@*CONCLUSION@#Arthroscopic double-pulley suture-bridge technique can achieve the effect of suture bridge operation, reduce the cost of operation and the risk of type 2 retear, and the early effectiveness is satisfactory, but the shoulder joint movement is limited within 3 months after operation.

ABSTRACT

OBJECTIVE@#To explore the feasibility and early effectiveness of computer-simulated osteotomy based on the health-side combined with guide plate technique in the treatment of cubitus varus deformity in adolescents.@*METHODS@#The clinical data of 23 patients with cubitus varus deformity who met the selection criteria between June 2019 and February 2023 were retrospectively analyzed. There were 17 males and 6 females, ranging in age from 4 to 16 years with an average of 8.5 years. The time from injury to operation was 1-4 years. The angle of distal humerus rotation was defined by humeral head posterior inclination angle using low radiation dose CT to scan the patient's upper extremity data at one time, and the preoperative rotation of the distal humerus on the affected side was (33.82±4.39)°. The CT plain scan data were imported into 9yuan3D digital orthopaedic system (V3.34 software) to reconstruct three-dimensional images of both upper extremities. The simulated operation was performed with the healthy upper extremity as the reference, the best osteotomy scheme was planned, overlapped and compared, and the osteotomy guide plate was prepared. The patients were followed up regularly after operation, and the formation of callus in the osteotomy area was observed by X-ray examination. Before and after operation, the carrying angle of both upper extremities (the angle of cubitus valgus was positive, and the angle of cubitus varus was negative) and anteversion angle were measured on X-ray and CT images. At the same time, the flexion and extension range of motion of elbow joint and the external rotation range of motion of upper extremity were measured, and Mayo score was used to evaluate the function of elbow joint.@*RESULTS@#The operation time ranged from 34 to 46 minutes, with an average of 39 minutes. All patients were followed up 5-26 months, with a mean of 14.9 months. All the incisions healed by first intention after the operation; 2 patients had nail path irritation symptoms after Kirschner wire fixation, which improved after dressing change; no complication such as breakage and loosening of internal fixators occurred after regular X-ray review. Continuous callus formed at the osteotomy end at 4 weeks after operation, and the osteotomy end healed at 8-12 weeks after operation. At last follow-up, the carrying angle, anteversion angle, external rotation range of motion, and extension and flexion range of motion of the elbow joint of the affected side significantly improved when compared with preoperative ones ( P<0.05). Except for the extension range of motion of the healthy elbow joint ( P<0.05), there was no significant difference in other indicators between the two sides ( P>0.05). At last follow-up, the Mayo elbow score was 85-100, with an average of 99.3; 22 cases were excellent, 1 case was good, and the excellent and good rate was 100%.@*CONCLUSION@#Computer-simulated osteotomy based on health-side combined with guide plate technique for treating cubitus varus deformity in adolescents can achieve precise osteotomy, which has the advantages of short operation time and easy operation, and the short-term effectiveness is satisfactory.

ABSTRACT

The shoulder joint is the most flexible joint in the body with the largest range of motion, and the movement pattern is more complex. Accurate capture of three-dimensional motion data of the shoulder joint is crucial for biomechanical evaluation. Optical motion capture systems offer a non-invasive and radiation-free method to capture shoulder joint motion data during complex movements, enabling further biomechanical analysis of the shoulder joint. This review provides a comprehensive overview of optical motion capture technology in the context of shoulder joint movement, including measurement principles, data processing methods to reduce artifacts from skin and soft tissues, factors influencing measurement results, and applications in shoulder joint disorders.

ABSTRACT

OBJECTIVE@#To design customized titanium alloy lunate prosthesis, construct three-dimensional finite element model of wrist joint before and after replacement by finite element analysis, and observe the biomechanical changes of wrist joint after replacement, providing biomechanical basis for clinical application of prosthesis.@*METHODS@#One fresh frozen human forearm was collected, and the maximum range of motions in flexion, extension, ulnar deviation, and radialis deviation tested by cortex motion capture system were 48.42°, 38.04°, 35.68°, and 26.41°, respectively. The wrist joint data was obtained by CT scan and imported into Mimics21.0 software and Magics21.0 software to construct a wrist joint three-dimensional model and design customized titanium alloy lunate prosthesis. Then Geomagic Studio 2017 software and Solidworks 2017 software were used to construct the three-dimensional finite element models of a normal wrist joint (normal model) and a wrist joint with lunate prosthesis after replacement (replacement model). The stress distribution and deformation of the wrist joint before and after replacement were analyzed for flexion at and 15°, 30°, 48.42°, extension at 15°, 30°, and 38.04°, ulnar deviation at 10°, 20°, and 35.68°, and radial deviation at 5°, 15°, and 26.41° by the ANSYS 17.0 finite element analysis software. And the stress distribution of lunate bone and lunate prosthesis were also observed.@*RESULTS@#The three-dimensional finite element models of wrist joint before and after replacement were successfully constructed. At different range of motion of flexion, extension, ulnar deviation, and radial deviation, there were some differences in the number of nodes and units in the grid models. In the four directions of flexion, extension, ulnar deviation, and radial deviation, the maximum deformation of wrist joint in normal model and replacement model occurred in the radial side, and the values increased gradually with the increase of the range of motion. The maximum stress of the wrist joint increased gradually with the increase of the range of motion, and at maximum range of motion, the stress was concentrated on the proximal radius, showing an overall trend of moving from the radial wrist to the proximal radius. The maximum stress of normal lunate bone increased gradually with the increase of range of motion in different directions, and the stress position also changed. The maximum stress of lunate prosthesis was concentrated on the ulnar side of the prosthesis, which increased gradually with the increase of the range of motion in flexion, and decreased gradually with the increase of the range of motion in extension, ulnar deviation, and radialis deviation. The stress on prosthesis increased significantly when compared with that on normal lunate bone.@*CONCLUSION@#The customized titanium alloy lunate prosthesis does not change the wrist joint load transfer mode, which provided data support for the clinical application of the prosthesis.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies.@*METHODS@#A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI.@*RESULTS@#All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up.@*CONCLUSION@#For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening.@*METHODS@#The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded.@*RESULTS@#After the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation ( P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case.@*CONCLUSION@#Ulnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection.@*METHODS@#The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score.@*RESULTS@#All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up ( P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%.@*CONCLUSION@#Limited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.

ABSTRACT

OBJECTIVE@#To investigate the changes of knee joint kinematics after anterior cruciate ligament (ACL) reconstruction assisted by personalized femoral positioner based on the apex of deep cartilage (ADC).@*METHODS@#Between January 2021 and January 2022, a total of 40 patients with initial ACL rupture who met the selection criteria were randomly divided into the study group (using the personalized femoral positioner based on ADC design to assist ACL reconstruction) and the control group (not using the personalized femoral positioner to assist ACL reconstruction), with 20 patients in each group. Another 20 volunteers with normal knee were collected as a healthy group. There was no significant difference in gender, age, body mass index, and affected side between groups ( P>0.05). Gait analysis was performed at 3, 6, and 12 months after operation using Opti _ Knee three-dimensional knee joint motion measurement and analysis system, and the 6 degrees of freedom (flexion and extension angle, varus and valgus angle, internal and external rotation angle, anteroposterior displacement, superior and inferior displacement, internal and external displacement) and motion cycle (maximum step length, minimum step length, and step frequency) of the knee joint were recorded. The patients' data was compared to the data of healthy group.@*RESULTS@#In the healthy group, the flexion and extension angle was (57.80±3.45)°, the varus and valgus angle was (10.54±1.05)°, the internal and external rotation angle was (13.02±1.66)°, and the anteroposterior displacement was (1.44±0.39) cm, the superior and inferior displacement was (0.86±0.20) cm, and the internal and external displacement was (1.38±0.39) cm. The maximum step length was (51.24±1.29) cm, the minimum step length was (45.69±2.28) cm, and the step frequency was (12.45±0.47) step/minute. Compared with the healthy group, the flexion and extension angles and internal and external rotation angles of the patients in the study group and the control group decreased at 3 months after operation, and the flexion and extension angles of the patients in the control group decreased at 6 months after operation, and the differences were significant ( P<0.05); there was no significant difference in the other time points and other indicators when compared with healthy group ( P>0.05). In the study group, the flexion and extension angles and internal and external rotation angles at 6 and 12 months after operation were significantly greater than those at 3 months after operation ( P<0.05), while there was no significant difference in the other indicators at other time points ( P>0.05). There was a significant difference in flexion and extension angle between the study group and the control group at 6 months after operation ( P<0.05), but there was no significant difference of the indicators between the two groups at other time points ( P>0.05).@*CONCLUSION@#Compared with conventional surgery, ACL reconstruction assisted by personalized femoral positioner based on ADC design can help patients achieve more satisfactory early postoperative kinematic results, and three-dimensional kinematic analysis can more objectively and dynamically evaluate the postoperative recovery of knee joint.

ABSTRACT

OBJECTIVE@#To explore the mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion (PASTA) lesion.@*METHODS@#A clinical data of 39 patients with PASTA lesions, who underwent the arthroscopic "mini incision" transtendon repair and met the selected criteria between May 2017 and April 2021, was retrospectively analyzed. There were 13 males and 26 females, with an average age of 63.7 years (range, 43-76 years). Nine patients underwent trauma history, and no obvious inducement was found in the other 30 patients. The main clinical symptom was shoulder pain with positive hug resistance test. The interval from symptom onset to operation was 3-21 months (mean, 8.3 months). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, American Association of Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention with no complications such as incision infection or nerve injury. All patients were followed up 24-71 months (mean, 46.9 months). The VAS, UCLA, and ASES scores significantly improved at 24 months after operation when compared with preoperative ones ( P<0.05). The ROMs of forward flexion and external rotation of the shoulder joint significantly increased at 3 and 24 months, and further increased at 24 months compared to 3 months, with significant differences ( P<0.05). However, the ROM of abduction of the shoulder joint at 3 months did not significantly improve compared with that before operation ( P>0.05), and it was significantly greater at 24 months than before operation and at 3 months after operation ( P<0.05). At last follow-up, the patients were very satisfied with the effectiveness in 30 cases (76.9%), satisfied in 5 cases (12.8%), and dissatisfied in 4 cases (10.3%). At 6 months after operation, 31 patients underwent reviews of MRI scans, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing, and 3 patients underwent tendon re-tear.@*CONCLUSION@#Arthroscopic "mini incision" transtendon repair in treatment of PASTA lesion could obtain satisfying mid-term effectiveness with low risk of tendon re-tear.

ABSTRACT

OBJECTIVE@#To investigate the short- and mid-term effectiveness of unicompartmental knee arthroplasty (UKA) for post-traumatic arthritis (PTA) of knee.@*METHODS@#The clinical data of 30 patients with PTA of unilateral knee between March 2014 and September 2021 was retrospectively analyzed. There were 14 males and 16 females with an average of 64.5 years (range, 33-81 years). The average body mass index was 26.7 kg/m 2 (range, 19.8-35.6 kg/m 2). The types of injuries that caused PTA included intra-articular fracture in 16 cases, extra-articular fracture in 8 cases, and soft tissue injury in 6 cases. The initial injuries were treated by conservative therapy in 12 cases and by surgical therapy in 18 cases. Ten cases were medial compartment osteoarthritis and 20 cases were lateral compartment osteoarthritis. According to Kellgren-Lawrence staging, there were 19 cases of grade Ⅲ and 11 cases of grade Ⅳ. The operative time, the length of hospital stay, complications, and subjective satisfaction were recorded. The Oxford Knee Function Score (OKS), Hospital for Special Surgery (HSS) score, and knee range of motion (ROM) were used to evaluate knee function. Weight-bearing X-ray films were taken to measure the femoro-tibial angle (FTA) and to assess alignment correction of the lower limb.@*RESULTS@#The operative time ranged from 50 to 95 minutes (mean, 63.7 minutes), the length of hospital stay ranged from 3 to 8 days (mean, 6.9 days). Superficial infection occurred in 2 patients, while the remaining incisions healed by first intention. There was no deep vein thrombosis or neurovascular injury. All patients were followed up 17-109 months (median, 70 months). At last follow-up, OKS score, HSS score, and ROM in 30 cases significantly improved when compared with those before operation (P<0.05). Lower limb alignment was significantly corrected and there was significant difference in FTA of the varus and valgus knees between pre- and post-operation ( P<0.05). The patient satisfaction rate was 86.7% (26/30). Two cases developed contralateral osteoarthritis progression during follow-up. No bearing dislocation, prosthesis loosening or sinking occurred and none required further revision.@*CONCLUSION@#For patients with PTA of knee, UKA can obtain definite short- and mid-term effectiveness with high patient satisfaction.
