Compartment Syndrome following Intramedullary Nail Fixation in Closed Tibial Shaft Fractures

@#Introduction: Compartment syndrome complicating intramedullary nailing of closed tibia fractures has been described as early as the 1980s, but currently remains less described in literature compared to compartment syndrome directly following trauma. This study aims to review this potentially disabling complication and highlight the importance of timely diagnosis and management of compartment syndrome following fracture fixation, not just after fracture itself, via a review of three cases. Material and methods: A retrospective study of a series of three cases was conducted. The type of fracture, wait time to fixation, surgery duration, reaming, size of nail implant used, tourniquet time, and surgical technique were recorded. Time to diagnosis of compartment syndrome, compartment pressure if available, extent of muscle necrosis, reconstructive procedures performed, and post-operative complications were analysed. Results: The three cases following high-energy trauma from road traffic accidents presented from January to May 2010. Compartment syndrome was diagnosed clinically for all cases, between one to six days post-operatively and supported by elevated compartment pressure measurements in two of the three cases. Conclusion: This study advocates thorough clinical monitoring and maintaining strong clinical suspicion of compartment syndrome in patients even after intramedullary nail fixation of tibial shaft fractures to achieve timely limbsalvaging intervention. While intercompartmental pressure can be used to aid in diagnosis, we do not advise using it in isolation to diagnose compartment syndrome. Tendon transfer improves functional mobility and provides a good result in patients with severe muscle damage, while skin grafting sufficient in patients with minimal muscle damage.

Results of Latissimus Dorsi Transfer using a Tendinous Allograft through a Single Deltopectoral Approach for Irreparable Posterosuperior Rotator Cuff Tears / Resultados da transferência do grande dorsal alongado com enxerto tendíneo homólogo por via delto-peitoral para lesões póstero-superiores irreparáveis do manguito rotador

Abstract Objective The primary aim of the present study is to evaluate the functional results of a modification to the latissimus dorsi (LD) transfer around the shoulder for irreparable posterosuperior rotator cuff tears. The secondary aim is to evaluate variables that might influence the outcomes. Surgical Technique Through a single deltopectoral approach, the LD tendon is detached, reinforced, and elongated with a tendinous allograft, transferred around the humerus, and fixed superolaterally to the greater tuberosity and anteriorly to the subscapularis. Methods Retrospective functional evaluation of 16 cases. The average follow-up was 21 months (12-47). The postoperative results (at last follow-up) were compared with the preoperative ones, as well as to other pre, intra, and postoperative variables. Results All (but one) patients were satisfied. Average University of California, Los Angeles (UCLA) score increased from 11.6 (8-16) to 27.3 (17-30) (p< 0.001). Improvements of shoulder pain, function, and strength achieved statistical significance (p< 0.001). Nonetheless, normal strength was never restored. Average active range of motion improved as follows: forward elevation, from 106° (60-140°) to 145° (130-160°) (p< 0.001); external rotation from 30° (0° to 60°) to 54° (40-70°) (p< 0.001); and internal rotation from L1 (gluteus to T7) to T10 (T12-T3) (p< 0.05). No complication has occurred. Preoperative pseudoparesis was reverted in all the six cases in which it was present. None of the variables analyzed influenced the outcomes, including pseudoparesis. Conclusions At early follow-up, this technique is safe and effective at recovering from pseudoparesis and at improving shoulder pain, function, and strength.

Resumo Objetivo O objetivo primário do presente trabalho é avaliar os resultados funcionais de uma modificação na transferência do grande dorsal no ombro para o tratamento de lesões póstero-superiores irreparáveis do manguito rotador. O objetivo secundário é avaliar as variáveis que podem influenciar os resultados. Técnica cirúrgica Por meio de uma única abordagem deltopeitoral, o tendão do músculo grande dorsal é desinserido reforçado e alongado com um enxerto tendíneo homólogo, transferido para o úmero e fixado em posição superolateral ao tubérculo maior e anterior ao músculo subescapular. Métodos Avaliação funcional retrospectiva de 16 casos. O período médio de acompanhamento foi de 21 meses (12-47 meses). Os resultados pós-operatórios (no último acompanhamento) foram comparados aos pré-operatórios, bem como a outras variáveis pré, intra e pós-operatórias. Resultados Todos os pacientes ficaram satisfeitos (exceto um). A pontuação média da University of California, Los Angeles (UCLA) aumentou de 11,6 (8-16) para 27,3 (17-30) (p< 0,001). A dor, a função e a força do ombro apresentaram melhora estatisticamente significativa (p< 0,001). A força, porém, não voltou ao valor normal. A amplitude de movimento ativa média apresentou as seguintes melhoras: elevação frontal, de 106° (60-140°) para 145° (130-160°) (p< 0,001); rotação externa, de 30° (0-60°) para 54° (40-70°) (p< 0,001); e rotação interna, de L1 (glúteo a T7) para T10 (T12-T3) (p< 0,05). Nenhuma complicação foi observada. A pseudoparesia pré-operatória foi revertida em todos os seis casos em que foi observada. Nenhuma das variáveis analisadas influenciou os desfechos, nem mesmo a pseudoparesia. Conclusões A curto prazo essa técnica é segura e eficaz na recuperação da pseudoparesia e na melhora da dor, da função e da força do ombro.

ABSTRACT Objective: To evaluate the functional results of surgically correcting drop foot in patients with leprosy and compare their SALSA, Social Participation, and AOFAS score. Methods: Overall, 22 patients were subjected to posterior tibial tendon transfer via the subcutaneous route to the foot dorsum with an average follow-up of 56 months (min 12, max 70). In our sample, 15 of the enrolled patients were men and seven, women, aged between 20 and 73 years old who were operated on from January 2014 to December 2017. The Pearson's correlation test (r) was used to measure the correlation among those scales. A p < 0.05 was considered significant between the pre- and pos-operative AOFAS scale scores. Results: Pre-operative average AOFAS score was 59.6 (min 35, max 74) and 77.2 postoperative (min 36, max 97) (p < 0.0001), postoperative Salsa and Social Participation scale, 30.6 and 22.5, respectively. Statistical analysis suggests a strong positive correlation between AOFAS and Salsa scales (r = −0.83) and AOFAS and social participation (r = −0.78). Average dorsiflexion was 5.4 degrees. Conclusion: The surgical correction of drop foot positively affects the quality of life and social participation of patients with leprosy. Level of Evidence III, Retrospective Study.

Treatment of recurrent anterior shoulder dislocation with bristow-latarjet procedure / Tratamento da luxação anterior recidivante do ombro pela técnica de bristow-latarjet

ABSTRACT Objectives: To describe the clinical and radiographic results of patients with traumatic recurrent anterior shoulder dislocation treated with the Bristow-Latarjet procedure. Methods: Retrospective case series including 44 patients (45 shoulders) who underwent the Bristow-Latarjet procedure. The graft was fixed "standing" in 84% of the shoulders, and "lying" in 16%. Results: The follow-up was 19.25 ± 10.24 months. We obtained 96% of good results, with 2 recurrences presented as subluxation. Graft healing occurred in 62% of cases. The graft was positioned below the glenoid equator in 84% of the cases, and less than 10 mm from its edge in 98%. The external rotation had a limitation of 20.7º ± 15.9º, while the internal rotation was limited in 4.0º ± 9.6º. The limitation of rotation and the position of the graft ("standing" or "lying") did not correlate with graft healing (p>0.05). Bicortical fixation was positively correlated with healing (p <0.001). Conclusion: The Bristow-Latarjet technique is indicated for the treatment of recurrent anterior dislocations and subluxations of the shoulder. It is a safe treatment method, which can be used in people with intense physical activity. Limiting shoulder mobility does not prevent patients from returning to their usual occupations. Level of Evidence IV, Case series.

RESUMO Objetivos: Descrever os resultados clínicos e radiográficos do tratamento da luxação anterior recidivante traumática do ombro pela técnica de Bristow-Latarjet. Métodos: Série de casos retrospectiva, incluindo 44 pacientes (45 ombros) submetidos à técnica de Bristow-Latarjet. O enxerto foi fixado "em pé" em 84% dos ombros, e "deitado" em 16%, utilizando 1 parafuso metálico. Resultados: O seguimento foi de 19,25 ± 10,24 meses. Obtivemos 96% de bons resultados, sendo 2 recidivas sob a forma de subluxação. A consolidação ocorreu em 62% dos casos. O enxerto foi posicionado abaixo do equador da glenoide em 84% das vezes, e a menos de 10 mm da sua borda em 98%. A rotação externa apresentou limitação de 20,7º ± 15,9º, enquanto a rotação interna 4,0º ± 9,6º. A limitação das rotações e a posição do enxerto ("em pé" ou 'deitado") não se correlacionaram com a consolidação do enxerto. A fixação bicortical correlacionou-se positivamente com a consolidação. Conclusões: A técnica de Bristow-Latarjet está indicada para o tratamento da instabilidade anterior recidivante do ombro. É um método de tratamento seguro, que pode ser utilizado em pessoas com atividade física intensa. A limitação da mobilidade do ombro não impede os pacientes de voltarem às suas ocupações habituais. Nível de Evidência IV, Série de casos.

Objective:To evaluate the curative effect of arthroscopic long head of biceps tendon (LHBT) transfer to reconstruct shoulder superior capsule for repairing massive rotator cuff tears.Methods:A retrospective case-control study was conducted on clinical data of 64 patients with massive rotator cuff tears admitted to Shanghai Tenth People's Hospital of Tongji University between December 2017 to January 2019. There were 26 males and 38 females, with the age of 50-75 years [(62.5±4.8)years]. All patients were treated by arthroscopic superior capsular reconstruction with LHBT. The shoulder range of motion in flexion, abduction, external rotation, acromiohumeral distance, visual analogue scale (VAS), Constant-Murley score and American Shoulder and Elbow Surgeons (ASES) score were evaluated and recorded before operation and at the last follow-up. The MRI was used to evaluate the integrity of the reconstructed structure at the last follow-up and rotator cuff re-tear rate. Postoperative complications were detected.Results:All patients were followed up for 13-25 months [(18.2±4.3)months]. At the last follow-up, the shoulder range of motion was (149.5±7.8)° in flexion, (162.0±6.6)° in abduction, and (60.6±11.8)° in external rotation; the acromiohumeral distance was (7.4±0.6)cm, the VAS was 1.0(0.0, 1.0)points, the Constant-Murley score was (90.5±2.6)points, the ASES was (90.8±4.2)points, which were significantly improved compared with those before operation [flextion: (73.8±5.3)°, abduction: (85.8±5.5)°, external rotation: (34.3±5.8)°, acromiohumeral distance: (5.9±0.8)cm, VAS: 6.5(6.0, 7.0)points, Constant-Murley score: (41.8±5.4)points, ASES: (41.4±6.1)points, respectively]( P<0.01). of all, 56 patients had intact reconstruction structure at the last follow-up, 7 patient with smalll retears in the reconstruction were not revised, and 1 patient underwent revision operation after reconstruction failure. The retear rate after rotator cuff repair was 13% (8/64). There were no obvious surgical complications after operation, with the incision free from infection. Conclusion:Arthroscopic superior capsular reconstruction with LHBT for repairing massive rotator cuff is safe and reliable, which can effectively relieve the pain of shoulder joint, recover the function and improve the joint mobility.

Huber opposition transfer for improving hypoplastic thumb: results of a case series / Transferencia de Huber para mejorar la oposición del pulgar hipoplásico: resultados de una serie de casos

Abstract Introduction: Abductor digiti minimi transfer (also known as Huber opposition transfer) allows restoring thumb opposition. This method has several advantages over other opposition transfer techniques, as it replaces the intrinsic muscles of the thumb with another intrinsic muscle of the hypothenar region, thus improving the volume of thenar eminence. It is used preferably in thumb hypoplasia types II and III. Objective: To describe the functional results of a series of patients with thumb hypoplasia who underwent Huber opposition transfer. Materials and methods: Descriptive, observational study conducted in 11 patients with thumb hypoplasia who underwent Huber opposition transfer and with a minimum follow-up of 6 months. Furthermore, some of these patients had undergone pollicization due to their type of hypoplasia. Results: The average age at the time of surgery was 35 months and the average follow-up period was 15.4 months. Average opposition function, according to the modified Kapandji index, improved from 1.63 (range 1-2) to 3.72 (range 2-4). Conclusion: Good functional results were obtained using this technique, achieving overall improvement in opposition function according to the Kapandji index. In 9 patients, the index increased to grade 4 and in 1 it went from grade 1 to grade 3; in 1 case, improvement was not significant (grade 1 to grade 2), since the patient presented with finger stiffness associated with VACTERL. Huber opposition transfer allows achieving good functional opposition results in patients with thumb hypoplasia.

Resumen Introducción.

Este procedimiento es usado preferiblemente en los tipos II y III de hipoplasia de pulgar. Objetivo. Describir los resultados funcionales de la transferencia de Huber en una serie de pacientes con hipoplasia de pulgar. Materiales y métodos. Estudio observacional descriptivo realizado en 11 pacientes con hipoplasia de pulgar operados mediante la técnica Huber y a quienes se les había realizado un seguimiento mínimo de 6 meses. Además, algunos habían sido sometidos a pulgariza-ción debido al tipo de hipoplasia que presentaban. Resultados. La edad promedio de los participantes al momento de la cirugía fue de 35 meses y el tiempo promedio de seguimiento fue de 15.4 meses. El promedio de la función de oposición, según la escala modificada de Kapandji mejoró de 1.63 (intervalo de 1-2) a 3.72 (intervalo 2-4). Conclusión. Se obtuvieron buenos resultados funcionales al emplear esta técnica, logrando una mejora general de la oposición según la escala de Kapandji: en 9 pacientes aumentó a grado 4 y en otro pasó de 1 a 3; solo en 1 caso la mejora no fue significativa (grado 1 a 2) dado que el paciente presentaba rigidez de los dedos asociada a VACTERL. La transferencia de Huber es una técnica que permite obtener buenos resultados funcionales de oposición para el pulgar hipoplásico.

ABSTRACT Introduction: Spontaneous rupture of the Achilles tendon is a frequent condition in young patients who practice sports. When the initial diagnosis is not made, it becomes a chronic injury, consequently, diagnosis and treatment is even more complex. In most of these cases, tendon grafts are necessary. Objective: To demonstrate the efficacy and functional clinical results of the surgical repair of the chronic rupture of the Achilles tendon by transferring the short lateral peroneal tendon. Case report: We report the case of a 38-year-old male patient with a history of a fall while playing sports. A chronic rupture of the Achilles tendon was found. Open surgery was performed, the short lateral peroneal tendon was transferred to the distal end of the Achilles tendon. The plasty was reinforced with the thin plantar tendon. Ankle boot-type immobilization was placed with 30° plantar flexion for six weeks. After this time, the patient received a walker boot, ambulation and rehabilitation began. The latter started with partial support during three months. At six months this patient returned to his normal life with adequate foot and ankle function. Conclusions: Surgical repair of chronic Achilles tendon rupture by transferring the short lateral peroneal tendon is an effective method and offers good clinical and functional results(AU)

Irreparable Massive Rotator Cuff Tear in a Young Patient With Recurrent Anterior Shoulder Dislocation

@#Combined latissimus dorsi transfer, subscapularis repair and Latarjet surgery is rare and has never been reported. A 35-year-old man with chronic shoulder pain had a long history of instability of his right shoulder. The first episode occurred during a game of touch rugby followed by multiple episodes of subluxation. MRI was done which showed complete tear of the subscapularis anteriorly which was retracted and atrophied indicating a longstanding tear. There was also significant mid substance supraspinatus tendon tear. Patient then underwent two surgeries. The initial surgery found the rotator cuff to be irreparable with glenoid bone loss and only acromioplasty with acromioclavicular joint resection were performed. He then had a single stage surgery consisting of latissimus dorsi transfer, Latarjet procedure and subscapularis repair. A two-stage surgery can be avoided, and good results can be obtained provided that the patient undergo correct rehabilitation regime after undergoing a single stage surgery.

Effectiveness of tibialis posterior tendon transfer for foot drop secondary to peroneal nerve palsy / 中国修复重建外科杂志

Objective: To investigate the effectiveness of tibialis posterior tendon transfer for foot drop secondary to peroneal nerve palsy. Methods: The clinical data of 21 patients with unilateral foot drop secondary to peroneal nerve palsy between October 2009 and September 2016 was retrospectively analyzed. There were 12 males and 9 females with an average age of 32.1 years (range, 23-47 years). The causes of peroneal nerve injury were iatrogenic injury in 7 cases, tibiofibular fractures combined with compartment syndrome in 5 cases, nerve exploration surgery after stab or cut injury in 3 cases, direct violence in 4 cases, and the fibular head fracture in 2 cases. The average time from injury to operation was 5.6 years (range, 2-8 years). There was 1 case of hallux valgus and 5 cases of toe flexion contracture. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, Foot and Ankle Ability Measure (FAAM) scores, range of motion (ROM), and dorsiflexion strength of ankle joint were used to evaluated the ankle function. Radiographic evaluation for the changes of postoperative foot alignment included Meary angle, calcaneal pitch angle, and hindfoot alignment angle. Results: All incisions healed by first intention. All patients were followed up 18-42 months (mean, 30.2 months). The dorsiflexion strength of ankle joint recovered from grade 0 to grade 3-4 after operation. There was no patient with a postoperative flat foot deformity and claw toe during follow-up. There was no significant difference in Meary angle, calcaneal pitch angle, and hindfoot alignment angle between pre- and post-operation ( P>0.05). The AOFAS score, FAAM score, and ROM of dorsiflexion significantly improved at last follow-up when compared with preoperative values ( P<0.05); while there was no significant difference in ROM of plantar-flexion between pre- and post-operation ( t=4.239, P=0.158). There were significant differences in AOFAS score, FAAM score, and ROM of dorsiflexion between affected and healthy sides ( P<0.05); but no significant difference in ROM of plantar-flexion was found ( t=2.319, P=0.538). Conclusion: Tibialis posterior tendon transfer is an effective surgical option for foot drop secondary to peroneal nerve palsy. And no postoperative flat foot deformity occurred at short-term follow-up.

Latissimus Dorsi Tendon Transfer using Tendinous Allograft for Irreparable Rotator Cuff Lesions: Surgical Technique / Transferência tendínea do grande dorsal com enxerto tendíneo homólogo para as lesões irreparáveis do manguito rotador: técnica cirúrgica

Abstract Latissimus dorsi transfer around the shoulder is the most frequently used surgical technique to treat young patients with irreparable posterosuperior rotator cuff lesions. This technique, as initially described and popularized by Gerber et al., has two main drawbacks thatmay predispose to complications and unsatisfactory functional results: 1) postoperative rupture of the origin of the deltoid, as its detachment from the acromion is necessary during the superior approach to the shoulder; and 2) postoperative rupture of the transferred tendon. In an attempt to avoid these problems, the authors have developed the following modifications to the original technique. Through a deltopectoral approach, the latissimus dorsi tendon is identified and detached from the humerus shaft. After being reinforced and elongated with a tendinous allograft, it is transferred around the humerus and fixed to the superolateral aspect of the greater tubercle. No rigid thoraco-brachial immobilization is used postoperatively.

Resumo No contexto do tratamento cirúrgico dos pacientes jovens com lesões irreparáveis da porção posterossuperior do manguito rotador, a técnica mais usada é a transferência do tendão do grande dorsal para a porção superolateral do tubérculo maior, conforme descrita e preconizada por Gerber et al. Entretanto, duas características dessa técnica podemlevar a resultados ruins e complicações: (i) a deiscência da origem do deltoide, que ocorre devido à sua violação durante a criação da via em golpe de sabre e (ii) a ruptura pós-operatória da inserção da transferência. Na tentativa de solucionar esses dois problemas, as seguintes modificações foram feitas à técnica cirúrgica original. Por meio de uma única via deltopeitoral, o tendão do grande dorsal é isolado e desinserido do úmero. Ele é então alongado e reforçado com um enxerto tendíneohomólogo, transferido ao redor do úmero e fixado à porção superolateral do tubérculomaior. Não foi usada imobilização pós-operatória comórtese toracobraquial rígida.

Arthroscopic-assisted Latissimus Dorsi Tendon Transfer for the Management of Irreparable Rotator Cuff Tears in Middle-aged Physically Active Patients

BACKGROUND: Latissimus dorsi (LD) tendon transfer is used as a treatment option for massive irreparable posterosuperior rotator cuff tears, and recently, an arthroscopic-assisted technique was introduced. This study was undertaken to evaluate the clinical and radiological outcomes of arthroscopic-assisted LD tendon transfer for the management of irreparable rotator cuff tears in active middle-aged patients. METHODS: The records of five patients (two males) with irreparable tears involving the supraspinatus and infraspinatus tendons managed by arthroscopic-assisted LD tendon transfer were retrospectively reviewed. Clinical outcomes were assessed using the visual analogue scale (VAS) pain scale, American Shoulder and Elbow Surgeon's (ASES) scores, the University of California Los Angeles (UCLA) scale, and ranges of motion. Postoperative integrities of transferred tendon were evaluated by magnetic resonance imaging in 4 patients and by ultrasound in one. RESULTS: Mean patient age was 55 years (range, 48–61 years), and mean follow-up period was 20 months (range, 12.0–27.2 months). Mean VAS score significantly improved from 6.6 ± 2.6 preoperatively to 1.8 ± 2.5 postoperatively (p=0.009), mean ASES score increased from 67.6 ± 9.2 to 84.6 ± 15.1, and mean UCLA score from 18.0 ± 1.4 to 28.8 ± 8.5 (all p<0.001). Postoperative imaging of the transferred LD tendon showed intact repair in 4 patients. The remaining patient experienced LD transfer rupture and a poor outcome. CONCLUSIONS: Arthroscopic-assisted LD tendon transfer improved shoulder pain and function in patients with massive, irreparable rotator cuff tears, and may be an option for this condition, especially in physically active patients.

Anatomical study of the transfer of flexor digitorum superficialis nerve branch of median nerve to restore wrist extension and forearm pronation / Estudo anatômico da transferência do ramo do nervo mediano destinado ao músculo flexor superficial dos dedos para restaurar a extensão do punho e a pronação do antebraço

Abstract Objective To analyze the anatomical variations of the innervation of the flexor digitorum superficialis muscle and to determine if the branch of the median nerve that supply this muscle is connected to the branches to the extensor carpi radialis brevis and the pronator teres muscles, without tension, and how close to the target-muscles the transfer can be performed. Methods Fifty limbs of 25 cadavers were dissected to collect data on the anatomical variations of the branches to the flexor digitorum superficialis muscle. Results This muscle received innervation from the median nerve in the 50 limbs. In 22 it received one branch, and in 28 more than one. The proximal branch was identified in 22 limbs, and in 12 limbs it shared branches with other muscles. The distal branch was present in all, and originated from the median nerve as an isolated branch, or a common trunk with the anterior interosseous nerve in 3 limbs, and from a common trunk with the flexor carpi radialis muscle and anterior interosseous nerve in another. It originated distally to the anterior interosseous nerve at 38, in 5 on the same level, and in 3 proximal to the anterior interosseous nerve. In four limbs, innervation came from the anterior interosseous nerve, as well as from the median nerve. Accessory branches of the median nerve for the distal portion of the flexor digitorum superficialis muscle were present in eight limbs. Conclusion In 28 limbs with two or more branches, one of them could be connected to the branches to the extensor carpi radialis brevis and pronator teres muscles without tension, even during the pronation and supination movements of the forearm and flexion-extension of the elbow.

RESUMO Objetivo Analisar as variações anatômicas da inervação do músculo flexor superficial dos dedos e determinar se o ramo do nervo mediano destinado a esse músculo pode ou não ser conectado aos ramos para os músculos extensor radial curto do carpo e pronador redondo sem tensão, e quão próximo dos músculos-alvo a transferência pode ser realizada. Métodos Foram dissecados 50 membros de 25 cadáveres para coletar dados sobre as variações anatômicas dos ramos para o músculo flexor superficial dos dedos. Resultados O referido músculo recebeu inervação do nervo mediano nos 50 membros. Em 22 recebeu um ramo, em 28 mais que um. O ramo proximal foi identificado em 22 membros e em 12 compartilhava ramos com outros músculos. O ramo distal estava presente em todos e desprendeu-se do nervo mediano como um ramo isolado ou de um tronco comum com o nervo interósseo anterior em 3 membros, e de um tronco comum com músculo flexor radial do carpo e nervo interósseo anterior em outro. Originou-se distalmente ao nervo interósseo anterior em 38, em 5 no mesmo nível e em 3 proximal ao nervo interósseo anterior.

Peroneal sulcus deepening combined with tendon transposition for the treatment of chronic peroneal tendon dislocation / 中华骨科杂志

Objective@#To introduce a combined operation for treating chronical peroneal tendon dislocation and to evalu-ate the clinical outcomes of patients.@*Methods@#Data of 12 ankles in 12 patients (male 9, female 3) with chronical peroneal ten-don dislocation who underwent the fibular groove deepening procedure with transposition of the peroneal longus muscle from June 2006 to August 2013 were retrospectively analyzed. The mean age was 24.6±4.3 years (range, 18-34 years), and there were 3 cas-es on left side, 9 on right side. The mechanism of peroneal tendon injury consisted of sports injuries in 8 and sprains in 4. There were 8 cases of flat fibula sulcus and 4 cases of convex. All patients met the inclusion criteria of a painful snapping or popping sen-sation or palpable clicking and positive provocation maneuver and without fracture and were treated with peroneal sulcus deepen-ing and peroneal longus tendon transposition. The duration of preoperative popping and pain symptoms ranged from 12 to 23 weeks, with an average of 16.9±4.0 weeks. All cases were treated conservatively 3-4 weeks before operation and were not effec-tive. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, visual anologue scale (VAS).@*Results@#Twelve patients were followed up with an average period of 37.3±7.0 (range, 25-50) months. The mean VAS scale score of all patients reduced from 5.6±0.9 to 0.5±0.7 at the latest follow-up. The mean AOFAS scale score improved from 61.4±5.6 to 92.6±4.2 at the latest follow-up. The difference between preoperative and postoperative was statis-tically significant. (t=16.250,-18.475; P=0.000). According to the evaluation of symptom and function scoring system, 10 cases were excellent and 2 cases were good, with an excellent rate of 100%. The mean postoperative return-sport time was 26.42±3.06 weeks (range, 23-32 weeks). All patients healed primarily and no infection, skin necrosis and residual redislocation occurred. The osteotomy healed completely without displacement, which was confirmed by imaging examination in three months postoperation. No patients had intractable pain after surgery, and they were able to perform daily activities at 3 months and physical exercise at 6 months after surgery. No slip occurred in all patients at the latest follow-up.@*Conclusion@#The fibular groove deepening procedure with transposition of the peroneal longus muscle can effectively treat chronical peroneal tendon dislocation and obtain good medi-um-term results.

Management of the paralyzed face using temporalis tendon transfer via intraoral and transcutaneous approach / 대한악안면성형재건외과학회지

Temporalis tendon transfer is a technique for dynamic facial reanimation. Since its inception, nearly 80 years ago, it has undergone a wealth of innovation to produce the modern operation. Temporalis tendon transfer is a relatively minimally invasive technique for the dynamic reanimation of the paralyzed face. This technique can produce significant and appropriate movement of the lateral oral commissure, more closely mimicking the normal side. The aim of this article is to review the technique of temporalis tendon transfer involving transferring of the coronoid process of the mandible with the insertion of the temporalis tendon via intra-oral and transcutaneous approach.

Rotura espontánea del tendón extensor largo del pulgar ­ transferencia tendínea con técnica anestésica WALANT / Spontaneous rupture of thumb extensor pollicis longus ­ tendon transfer under the WALANT anesthetics technique

La rotura espontanea del tendón extensor largo del pulgar (ELP), es una patología infrecuente existiendo casos reportados en la literatura donde no se logra encontrar factores predisponentes. El manejo quirúrgico suele realizarse utilizando una técnica de transposición tendínea del tendón del extensor propio del índice. En la actualidad, la técnica anestésica de WALANT "Wide Awake Local Anesthesia with No-Torniquet" ha sido de amplio desarrollo en la cirugía de la mano, sobre todo para la resolución quirúrgica de patología de tendones, con buenos y excelentes resultados. Se presenta un caso de un paciente con rotura espontánea del tendón ELP, que fue manejado con una transferencia tendínea utilizando la técnica anestésica WALANT.

The spontaneous rupture of thumb extensor pollicis longus (EPL) is a rare disease with just a few case reports known where no trigger factor has been found. The surgical management is done by the proper index extensor tendon transposition. Nowadays, the WALANT anesthetic technique ("Wide Awake Local Anesthesia with No-Torniquet") has had a broad development in hand surgery, especially in surgery for tendon injuries, with good and excellent results. A clinical case is shown with a patient who had a spontaneous EPL rupture which was managed with a tendon transfer under the WALANT anesthetics technique.

Introduction: the aim of the study was to analyze the clinical and radiological outcomes of a series of patients with massive ruptures of the rotator cuff treated with latissimus dorsi tendon transfer. Methods: A retrospective, descriptive and observational study was performed. Patients <70 years with massive and irreparable posterosuperior lesions of the rotator cuff were treated with latissimus dorsi transfer and with a minimum follow-up of 2 years. Range of motion and strength in abduction were assessed. In addition, the visual analogue scale and modified Constant-Murley scale were recorded. Acromio-humeral distance and arthropathy stage were radiographically analyzed. Results: Seventeen patients were included (12 males, 5 females), mean age 54 years (range 34-65), with a mean followup of 46 months (range 24-71). In the primary surgery group, the average motion gain was 53º in anterior flexion, 50º in abduction and 19º in external rotation. The abduction strength recorded an average gain of 1.4 kg. Modified Constant-Murley scale of 75.6 (range 63-80) at the end of follow-up. In the revision surgery group, the gain of active motion was 48º in anterior flexion, 30º in abduction and 10º in external rotation. Abduction strength had an average gain of 1.1 kg. Postoperative visual analogue scale improved 5.1 points in the primary surgery group and 3.4 in the other group. Conclusion: Latissimus dorsi tendon transfer for the treatment of massive posterosuperior rupture of the rotator cuff showed improvements in range of motion, strength, pain relief and shoulder function.
