ABSTRACT
La pérdida ósea en el sector anterior, ya sea por un defecto horizontal, vertical o combinado, actualmente es un desafío, no sólo por la integración del implante, sino por la estética involucrada. Entre las técnicas de regeneración ósea que permiten solucionar estos defectos, cabe destacar la técnica de expansión de crestas. Se presenta el caso de una paciente de 58 años con reborde atrófico, que se sometió a la expansión de crestas con colocación simultánea de implantes en sector anterior, con xenoinjerto previo a técnica de expansión de crestas con piezoeléctrico, colocación simultánea de implantes Narrow Connection SLActive Straumann. Se logró ganancia ósea y estabilidad primaria de los implantes, sin complicaciones. En escenarios seleccionados, la técnica de expansión de crestas de manera predecible permite ganancia de hueso horizontal adecuada, el éxito de los implantes con tasa de supervivencia y mínimas complicaciones intra y postoperatorias (AU)
Bone loss in the anterior sector, both a horizontal, vertical or combined defect is a challenge today; not only for the integration of the implant but also the aesthetic involved. There are techniques of bone regeneration that help us to solve this type of defects, among them we should highlight the crest expansion technique. We present the case of a 58-year-old patient with atrophic flange, who underwent the expansion of crests with simultaneous placement of implants in the anterior sector, with xenograft prior to the piezoelectric crest expansion technique, Simultaneous placement of Narrow Connection SLActive Straumann implants, bone gain and primary stability of the implants were obtained, without complications. In selected scenarios, the crest expansion technique could be considered a predictable approach that demonstrates a high implant survival rate, adequate horizontal bone gain, and minimal intra- and postoperative complications (AU)

OBJECTIVE@#To assess the effectiveness of supramalleolar osteotomy (SMOT) as a therapeutic intervention for varus-type ankle arthritis, while also examining the associated risk factors that may contribute to treatment failure.@*METHODS@#The clinical data of 82 patients (89 feet) diagnosed with varus-type ankle arthritis and treated with SMOT between January 2016 and December 2020 were retrospectively analyzed. The patient cohort consisted of 34 males with 38 feet and 48 females with 51 feet, with the mean age of 54.3 years (range, 43-72 years). The average body mass index was 24.43 kg/m 2 (range, 20.43-30.15 kg/m 2). The preoperative tibial anterior surface angle (TAS) ranged from 77.6° to 88.4°, with a mean of 84.4°. The modified Takakura stage was used to classify the severity of the condition, with 9 feet in stage Ⅱ, 41 feet in stage Ⅲa, and 39 feet in stage Ⅲb. Clinical functional assessment was conducted using the Maryland sore, visual analogue scale (VAS) score, and psychological and physical scores in Health Survey 12-item Short From (SF-12). Radiology evaluations include TAS, talar tilt (TT), tibiocrural angle (TC), tibial medial malleolars (TMM), tibiocrural distance (TCD), tibial lateral surface angle (TLS), and hindfoot alignment angle (HAA). The results of clinical failure, functional failure, and radiology failure were statistically analyzed, and the related risk factors were analyzed.@*RESULTS@#The operation time ranged from 45 to 88 minutes, with an average of 62.2 minutes. No complication such as fractures and neurovascular injuries was found during operation. There were 7 feet of poor healing of the medial incision; 9 pin tract infections occurred in 6 feet using external fixator; there were 20 cases of allograft and 3 cases of autograft with radiographic bone resorption. Except for 1 foot of severe infection treated with bone cement, the remaining 88 feet were primary healing, and the healing area was more than 80%. All patients were followed up 24-82 months, with an average of 50.2 months. Maryland score, VAS score, SF-12 psychological and physiological scores, and TAS, TC, TLS, TCD, TT, TMM, HAA, and Takakura stage were significantly improved at last follow-up ( P<0.05). Postoperative clinical failure occurred in 13 feet, functional failure in 15 feet, and radiology failure in 23 feet. Univariate analysis showed that obesity, TT>10°, and Takakura stage Ⅲb were risk factors for clinical failure, HAA≥15° and Takakura stage Ⅲb were risk factors for functional failure, and TT>10° was risk factor for radiographic failure ( P<0.05). Further logistic regression analysis showed that TT>10°, HAA≥15°, and TT>10° were risk factors for clinical failure, functional failure, and radiographic failure, respectively ( P<0.05).@*CONCLUSION@#SMOT is effective in the mid- and long-term in the treatment of varus-type ankle arthritis, but it should be used with caution in patients with obesity, severe hindfoot varus, severe talus tilt, and preoperative Takakura stage Ⅲb.

OBJECTIVE@#To investigate the effectiveness of single Taylor external fixator combined with biplanar osteotomy on correction of tibial multiplanar deformities.@*METHODS@#Between October 2016 and December 2021, 11 patients with tibial multiplanar deformities (20 sides) were treated with single Taylor external fixator and biplanar osteotomy. Of them, 4 were male and 7 were female; the average age ranged from 13 to 33 years (mean, 21.9 years). Diagnosis included rickets severe genu varum deformity (7 cases, 14 sides), rickets severe genu valgum deformity (2 cases, 4 sides), multiple osteochondromatosis calf deformity (1 case, 1 side), neurofibromatosis medial lower leg anterior arch deformity with short of leg (1 case, 1 side). After fibular osteotomy and tibial multiplanar osteotomy, a Taylor external fixator was installed. After operation, the deformities were corrected successively and fixed completely. The osteotomy healed, then the external fixator was removed. Before operation and at 12 months after operation, the full-length X-ray films were taken. The leg-length discrepancy, medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), and tibial rotation angle were measured. The degree of lower limb deformity was scored with reference to a customized tibial mechanical axis scoring table.@*RESULTS@#Osteotomy was successfully completed without neurovascular injury and other complications. The external fixator was adjusted for 28-46 days, with an average of 37 days, and the external fixator was worn for 136-292 days, with an average of 169 days. Mild needle infection during the fixation period occurred in 3 sides, refracture at the distal tibial osteotomy in 1 side after removing the external fixator, and nonunion of the distal fibular osteotomy in 1 side. All patients were followed up 369-397 days (mean, 375 days). At 12 months after operation, the lower limb discrepancy decreased, but there was no significant difference ( P>0.05). MPTA, LDTA, PPTA, ADTA, and tibial rotation angle improved, and the differences in LDTA, ADTA, and tibial rotation angle were significant ( P<0.05). The score of lower limb deformity was significantly higher than that before operation ( P<0.05), and the results were excellent in 9 sides, good in 8 sides, fair in 3 sides, with the excellent and good rate of 85%.@*CONCLUSION@#Single Taylor external fixator combined with biplanar osteotomy is effective in the correction of tibial multiplanar deformities.

OBJECTIVE@#To observe the clinical efficacy of intercondylar fossa plasty in preventing intercondylar fossa impingement syndrome after high tibial osteotomy.@*METHODS@#From August 2018 to August 2020, 84 patients with inverted knee osteoarthritis were treated by arthroscopy combined with high tibial osteotomy, and were divided into two groups with 42 cases in each group according to different surgical methods. In the intercondylar fossa plasty group, there were 13 males and 29 females, age ranged from 52 to 67 years old with an average of(58.27±4.32) years old, and arthroscopic intercondylar fossa plasty was performed first, and then high tibial osteotomy. In the arthroscopic cleansing group, 16 males and 26 females, age ranged from 50 to 71 years old with an average of (59.02±5.14) years old, underwent arthroscopic cleansing and then high tibial osteotomy. Postoperative treatment was evaluated using visual analogue scale(VAS), hospital for special surgery (HSS) score for the knee, and the occurrence of intercondylar percussa impingement.@*RESULTS@#All 84 patients were followed up, the duration ranged from 12 to 18 months with an average of (14.1±1.6) months. The VAS and HSS score of knee joint at 6, 12 and 18 months after surgery were significantly improved compared with preoperative period, and there was no significant difference between the two groups (P>0.05), but the incidence of intercondylar fossa index and intercondylar fossa impact between the two groups was significantly compared 18 months after surgery (P<0.05).@*CONCLUSION@#Intercondylar fossa plasty can effectively prevent the incidence of intercondylar fossa impact after high tibial osteotomy, and has a more significant effect on postoperative knee pain and function improvement.

OBJECTIVE@#To measure and compare medial proximal tibial angle (MPTA) of lower limbs under different axial rotation angles(neutral position, 30° internal rotation, 30° external rotation) on the load position radiographs, and explore changes and significance of MPTA measured within and between groups of tibia at different axial rotation positions.@*METHODS@#From January 2018 to December 2018, 40 patients with knee osteoarthritis (KOA) were selected, with a total of 80 limbs, including 12 males and 28 females, aged from 29 to 73 years old with an average of (59.6±12.7) years old. Full length radiographs of the lower limbs were taken on neutral tibia position, 30° internal rotation and 30° external rotation, respectively. MPTA was measured and the results were compared between groups and within groups.@*RESULTS@#MPTA measured on the left lower extremity of neutral tibia, 30° internal rotation and 30° external rotation were (86.08±2.48) °, (88.62±2.94) ° and (83.47±3.10) °, respectively. MPTA measured on the right lower limb were (86.87±1.97) °, (89.02±2.39) ° and (83.80±2.77) °, respectively, and there were no significant difference in MPTA measured between rotation angle group (P>0.05). While there were statistical difference in MPTA on the same limb between groups (P<0.05). On 30° internal rotation, MPTA of left and right lower limbs increased by (2.54±1.74) ° and (2.15±1.78) ° compared with tibia neutral position. On 30° external rotation, MPTA of left and right lower limbs decreased (2.61±2.03) ° and (3.07±1.75) ° compared with tibial neutral position.@*CONCLUSION@#When a full-length X-ray film is taken on the weight-bearing position of both lower limbs, if there is axial rotation or external rotation of tibia, MPTA will increase or decrease compared with neutral position, which may cause a certain degree of deviation in clinical operation based on the accurate measurement of MPTA. However, the extent to which this bias affects the clinical operation effect remains to be verified. In addition, limited by the total number of samples and the number of measurement groups, whether there is a linear relationship between MPTA deviation and tibial axial rotation needs to be further studied.

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.

OBJECTIVE@#To compare the effectiveness of subtalar arthroereisis (STA) combined with modified Kidner procedure versus STA alone in the treatment of flexible flatfoot combined with painful accessory navicular bone in children.@*METHODS@#The clinical data of 33 children with flexible flatfoot combined with painful accessory navicular bone who were admitted between August 2018 and August 2021 and met the selection criteria were retrospectively analyzed. They were divided into a combination group (17 cases, treated by STA combined with modified Kidner procedure) and a control group (16 cases, treated by STA alone) according to the surgical methods. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, affected side of the foot, disease duration, and preoperative visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, talus-first metatarsal angle (T1MT), talus-second metatarsal angle (T2MT), talonavicular coverage angle (TCA), talus first plantar angle (Meary angle), calcaneal inclination angle (Pitch angle), and heel valgus angle (HV). The operation time, incision length, intraoperative blood loss, number of intraoperative fluoroscopies, and perioperative complications were recorded in both groups. The anteroposterior, lateral, and calcaneal axial X-ray films for the affected feet were taken regularly, and T1MT, T2MT, TCA, Meary angle, Pitch angle, and HV were measured. The VAS score, AOFAS ankle-hindfoot score were used to evaluate pain and functional recovery before and after operation.@*RESULTS@#Surgeries in both groups were successfully performed without surgical complication such as vascular, nerve, or tendon injuries. Less operation time, shorter incision length, less intraoperative blood loss, and fewer intraoperative fluoroscopies were found in the control group than in the combination group ( P<0.05). One case in the combination group had partial necrosis of the skin at the edge of the incision, which healed after the dressing change and infrared light therapy, and the rest of the incisions healed by first intention. All children were followed up 12-36 months, with a mean of 19.6 months. At last follow-up, VAS score and AOFAS ankle-hindfoot score significantly improved in both groups when compared with preoperative ones ( P<0.05), and the differences of these scores between before and after operation improved more significantly in the combination group than in the control group ( P<0.05). Imaging results showed that the T1MT, T2MT, TCA, Meary angle, and HV significantly improved in both groups at last follow-up when compared with preoperative ones ( P<0.05), and the Pitch angle had no significant difference when compared with preoperative one ( P>0.05). But there was no significant difference in the difference of these indicators between before and after operation between the two groups ( P>0.05).@*CONCLUSION@#Both procedures are effective in the treatment of flexible flatfoot children with painful accessory navicular bone. STA has the advantage of minimally invasive, while STA combined with modified Kidner procedure has better effectiveness.

OBJECTIVE@#To compare the effectiveness of supramalleolar osteotomy (SMOT) and ankle arthrodesis (AA) in the treatment of inverted ankle osteoarthritis (OA) in Takakura 3A stage with talus tilt.@*METHODS@#The clinical data of 41 patients with inverted ankle OA in Takakura 3A stage with talus tilt admitted between January 2016 to January 2020 and met the selection criteria were retrospectively analyzed, and they were divided into SMOT group (21 cases) and AA group (20 cases) according to the surgical method. There was no significant difference in baseline data such as gender, age, affected side, cause of injury, and preoperative talar tilt angle (TT), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score, short-form 36 health survey scale (SF-36) score, and sagittal range of motion (ROM) between the two groups ( P>0.05). The operation time, intraoperative blood loss, partial weight-bearing time, and complications were recorded in the two groups. AOFAS ankle-hindfoot score, VAS score, SF-36 score, and sagittal ROM were used to evaluate the effectiveness. Bone healing was observed and the time of bony healing was recorded. In the SMOT group, the tibial lateral surface angle (TLS), TT, and the tibial articular surface angle (TAS) were measured on ankle joint weight-bearing anteroposterior and lateral X-ray films and compared with those before operation. And Takakura staging assessment was also performed.@*RESULTS@#The operation time and intraoperative blood loss in AA group were significantly less than those in SMOT group ( P<0.05). Patients in both groups were followed up 24-36 months, with an average of 28.9 months. Incision infection occurred in 2 patients in SMOT group and 1 patient in AA group, respectively, and no vascular or nerve injury occurred in both groups. The partial weight-bearing time of SMOT group was significantly less than that of AA group ( P<0.05), but there was no significant difference in bony healing time between the two groups ( P>0.05). At last follow-up, the difference of VAS score and SF-36 score before and after operation of AA group were less than those of SMOT group, and the difference of sagittal ROM before and after operation in SMOT group was less than that of AA group, with significant differences ( P<0.05). The difference of AOFAS ankle-hindfoot score before and after operation in AA group was slightly greater than that in SMOT group, but the difference was not significant ( P>0.05). The above scores in both groups significantly improved when compared with those before operation ( P<0.05). Sagittal ROM in AA group was significantly less than that before operation ( P<0.05), while there was no significant difference in SMOT group ( P>0.05). In the SMOT group, 17 patients (81.0%) showed improvement in imaging staging, 2 patients (9.5%) showed no improvement in staging, and 2 patients (9.5%) showed stage aggravation. TLS, TAS, and TT significantly improved when compared with those before operation ( P<0.05). At last follow-up, 2 patients in SMOT group received AA due to pain and stage aggravation, and 1 patient with bone nonunion underwent bone graft. Subtalar joint fusion was performed in 1 case of subtalar arthritis in AA group.@*CONCLUSION@#For inverted ankle OA in Takakura 3A stage with talus tilt, both SMOT and AA can significantly releave pain, improve foot function and quality of life, but AA has more definite effectiveness and better patient satisfaction.

Abstract Objective Clinodactyly is a congenital hand deformity that is characterized by coronal angular deviation and may occur in thumbs or fingers. Surgical treatment is indicated for severe angulations. Among the described techniques, one of the options consists of bone alignment by wedge-shaped addition osteotomy of the anomalous phalanx. Such alignment maneuver creates a problem in skin cover, along with soft-tissue tension at the concave aspect of the deformity. Hence, some sort of skin flap is required for the adequate operative wound closure. We aim to demonstrate the aforementioned technique and to assess the results of bilobed flap in the treatment of hand clinodactyly. Methods Retrospective study conducted between January 2008 and January 2015. Five patients were included in the study, including nine operated digits. Surgical indication consisted of angular deviations ˃ 30o. Neither patients with thumb deformities nor those with deformities associated to syndromes were excluded from the study. We assessed the functional and cosmetic outcomes of the technique, as well as complications and the satisfaction rates of the family. Results All patients had satisfactory functional and cosmetic results, with a mean skin healing of 18.6 days. Among nine operated digits, only one of the patients presented vascular compromise at the distal portion of the first flap lobe, albeit without necrosis or the need for any additional procedure. Patients were followed up on a minimum of 12-month interval. No deformity recurred during the observation period. Conclusion Bilobed flap for the treatment of hand clinodactyly is a good option for skin cover after the osteotomy.
Resumo Objetivo A clinodactilia é uma deformidade congênita da mão, caracterizada por desvio angular coronal, podendo ocorrer em polegares ou dedos. O tratamento cirúrgico é indicado para angulações severas. Dentre as técnicas descritas, uma das opções consiste no alinhamento ósseo, através de osteotomia em cunha de adição da falange anômala. Essa manobra de alinhamento gera uma dificuldade de cobertura cutânea, juntamente com a tensão das partes moles no lado côncavo da deformidade. Sendo assim, algum tipo de retalho cutâneo é necessário para o fechamento adequado da ferida cirúrgica. Objetivamos demonstrar a técnica citada e avaliar os resultados do retalho bilobado no tratamento das clinodactilias da mão. Métodos Estudo retrospectivo entre janeiro de 2008 e janeiro de 2015. Foram incluídos cinco pacientes no estudo, nove dedos foram submetidos à cirurgia. Tiveram indicação cirúrgica os pacientes com desvios angulares nos dedos acima de 30 graus. Não foram excluídos do estudo os pacientes com deformidades no polegar, nem aqueles com deformidades associadas a síndromes. Foram avaliados os resultados funcionais e estéticos com o uso desta técnica, assim como as complicações e o grau de satisfação dos familiares. Resultados Todos os pacientes apresentaram resultados funcionais e estéticos satisfatórios, com cicatrização cutânea média de 18,6 dias. Entre os nove dedos submetidos à cirurgia, apenas um dos pacientes apresentou comprometimento vascular na porção distal do primeiro lobo do retalho, porém sem necrose ou necessidade de qualquer procedimento adicional. Os pacientes foram acompanhados durante um intervalo mínimo de 12 meses. Nenhuma deformidade ocorreu durante o período de observação. Conclusão O uso do retalho bilobado no tratamento das clinodactilias da mão é uma boa opção para cobertura cutânea após a realização de osteotomia.

Con la osteotomía en un solo nivel, se puede lograr la corrección del eje de la extremidad en pacientes con deformidades combinadas femoral y tibial, pero de forma simultánea generará una alteración patológica de oblicuidad de la interlínea articular, lo que conducirá a elongación ligamentaria, inestabilidad, degeneración condral y, en última instancia, comprometerá su sobrevida y los resultados funcionales. En virtud del análisis de la literatura más reciente, podemos concluir que existe un número significativo de pacientes que requieren de un procedimiento combinado para lograr un objetivo biomecánico óptimo. La finalidad de una osteotomía en doble nivel alrededor de la rodilla consiste en restablecer la anatomía normal, descargar el compartimiento afectado, normalizar los ángulos mecánicos y la orientación de la interlínea articular. Los ejes fisiológicos pueden restablecerse a través de un análisis preoperatorio exhaustivo, respetando principios biomecánicos y fijación estable con placas bloqueadas. Es un procedimiento demandante y con indicaciones en evolución, que progresivamente se ha instaurado como una alternativa de tratamiento justificada en estudios clínicos y biomecánicos para el manejo de deformidades severas alrededor de la rodilla.
With single-level osteotomy, correction of the limb axis in patients with combined femoral and tibial deformities can be achieved. This correction, however, will generate a pathological alteration in the joint line oblicuity, leading to ligament elongation, instability, joint degeneration and, ultimately, it will compromise the longevity and functional results of the correction. By analyzing the most recent literature, we can conclude that there is a significant number of patients who require a combined procedure to achieve an optimal biomechanical goal. The purpose of a double-level osteotomy around the knee is to restore normal anatomy, unload the affected compartment, normalize the mechanical angles and the orientation of the joint line. Physiological axes can be reestablished by means of a thorough preoperative analysis, observing the biomechanical principles and stable fixation with locked plates. It is a demanding procedure with increasing indications, which has progressively been established in clinical and biomechanical studies as a justified treatment alternative for the management of severe deformities around the knee.

OBJECTIVE@#To compare clinical efficacy of scarf osteotomy and double metatarsal osteotomy(DMO) in treating moderate to severe hallux valgus.@*METHODS@#Fifty patients (81 feet) with moderate to severe hallux valgus deformity were treated from January 2017 to December 2019, and were divided into Scarf osteotomy (SO) group or DMO group according to different osteotomy methods. There were 26 patients (44 feet) in SO group, including 1 male and 25 females, aged from 48 to 65 years old with an average of (55.5±4.67) years old;18 patients (30 feet) with moderate and 8 patients (14 feet) with severe. There were 24 patients(37 feet) in DMO group, including 1 male and 23 females, aged from 45 to 62 years old with an average of (52.1±6.8) years old;there were 14 patients (24 feet) with moderate and 10 patients (13 feet) with severe. Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA) and relative length of the first metatarsal(RLFM) on weight-bearing anteroposterior radiographs before and after operation were compared. American Orthopaedic Foot and Ankle Society (AOFAS) hallux, metatarsal, and interphalangeal joint scores was used for evaluate clinical effects. Weight bearing time and complications were observed.@*RESULTS@#Fivty patients were followed up. The follow-up time in SO group ranged from 12 to 36 months with an average of(20.50±6.22) months and from 16 to 28 months with an avaerge of(19.80±2.44) months in DMO group while there was no significant difference between two groups(P>0.05). All incision healed at stage I, and osteotomy healed at (20.31±3.17) months after operation. One patient occurred hallux adduction deformity, without transferred metatarsalgia;2 patients occurred metastatic metatarsalgia in DMO group. There were no significant difference in HVA, IMA, DMAA, and AOFAS scores between two groups(P>0.05) before and after operation. There was no significant difference in RLFM between two groups(P>0.05), while had significant difference in RLFM between two groups at final follow-up (P<0.05). Partial weight-bearing time and full weight-bearing time in SO group were significantly earlier than those in DMO group (P<0.05).@*CONCLUSION@#Both of Scarf osteotomy and the first metatarsal biplane osteotomy could effectively treat moderate to severe hallux valgus deformity, with similar imaging and clinical evaluation. However, the relative length of the first metatarsal bone in SO group was longer than that in DMO group after operation, and the time of weight bearing in Scarf osteotomy is earlier than that of double metatarsal osteotomy of the first metatarsal.

OBJECTIVE@#To explore clinical effect of the first metatarsophalangeal joint fusion combined with lateral toe rotation Weil osteotomy in treating hallux valgus with severe metatarsal adduction.@*METHODS@#From March 2017 to August 2021, 37 patients ( 69 feet ) with severe plantar adductor hallux valgus were treated with the first metatarsophalangeal joint fusion combined with rotational Weil osteotomy were retrospectively analyzed, including 8 males(11 feet) and 29 females (58 feet), aged from 67 to 83 years old with an average of (70.03±2.87) years old;3 cases on the left side, 2 cases on the right side and 32 cases on both sides. Visual analogue scale(VAS) was used to evaluate degree of pain relief before operation, 6 weeks after operation and at the final follow-up. American Orthopaedic Foot and Ankle Surgery (AOFAS) forefoot score was used to evaluate function of the affected foot before operation and final follow-up. Hallux valgus angle(HVA) and intermetatarsal angle(IMA) were measured before operation and at the final follow-up.@*RESULTS@#Thirty-seven patients(69 feet) were followed up from 12 to 48 months with an average of(22.8±0.6) months. Bone healing was achieved at the first metatarsophalangeal joint from 7 to 10 weeks with an average of (8.00±1.21) weeks after operation, without delay and nonunion. HVA was increased from (44.30±2.84)° before operation to (15.20±2.13) °at the final follow-up, and had statistical difference(t=65.781, P<0.05);while no difference in IMA before and after operation(P>0.05). VAS was decreased from (6.73±1.48) points to (2.78±0.71) points at 6 months after operation(t=3.279, P<0.05), and had difference compared with the latest follow-up(1.16±1.12)(t=4.859, P<0.05). AOFAS forefoot score increased from (52.14±5.78) preoperatively to (86.70±4.86) at the fonal follow-up, and 25 feet got excellent results, 40 feet good and 4 feet fair.@*CONCLUSION@#The first metatarsophalangeal joint fusion combined with lateral toe rotation Weil osteotomy in treating severe plantar adduction hallux valgus could significantly relieve pain and appearance of forefoot, stabilize the first sequence, and significantly improve walking function.

OBJECTIVE@#To investigate the clinical effect of using lengthened trochanteric osteotomy wire fixation combined with autologous bone graft in patients undergoing revision total hip arthroplasty.@*METHODS@#From December 2010 to December 2018, 18 patients underwent revision of total hip arthroplasty with extended trochanteric osteotomy wire fixation and autogenous bone graft, including 8 males and 10 females with an average age of (78.89±3.32) years old ranging from 68 to 82 years. The time from the initial replacement to the revision was 9 to 22 (16.33±2.93) years. The patients were followed up regularly after operation. The healing time of osteotomy, the time of full weight-bearing activity, Harris score of hip joint and complications were recorded.@*RESULTS@#All 18 patients were followed up for 16 to 38 months with an average of (25.78±6.65) months. The incision length was 16 to 21 cm with an average of (18.89±1.32) cm; the operation time was 105 to 128 min with an average of (115.44±6.59) min, the bleeding volume was 240 to 285 ml with an average of (267.44±13.77) ml. The healing time of osteotomy was 12 to 18 weeks with an average of (15.61±1.75) weeks. Harris score of hip joint was (47.11±5.04) before operation, (76.39±3.85) during full weight-bearing activities, and (82.22±2.76) at the final follow-up(P<0.05). During the follow-up period, there were no complications such as limb shortening, infection, poor incision healing, prosthesis loosening and sinking, and periprosthetic fracture.@*CONCLUSION@#In revision total hip arthroplasty, the use of extended trochanteric osteotomy wire fixation combined with autologous bone graft can achieve satisfactory clinical results, but the surgeon needs to make a systematic plan for the pre-revision, intraoperative and postoperative recovery.

Proximal tibiofibular instability is a rare condition for which treatment is poorly codified. A 21-year-old patient, a leisure sportswoman, presented a post-traumatic anterolateral instability of the proximal tibiofibular articulation without cartilage lesion. We propose an original surgical technique based on a review of the literature that combines an anatomical ligamentoplasty of the proximal tibiofibular joint and a proximal fibular diaphyseal osteotomy to reduce the distal tibiofibular mechanical stresses. This original technique allows a favorable evolution with recovery of professional and sports activities at 6 months.

El trasplante dentario autólogo se define como el po-sicionamiento de una pieza dentaria autóloga en un alvéolo post extracción o en un lecho formado qui-rúrgicamente. Actualmente, siguiendo los criterios de selección adecuados y una técnica quirúrgica mi-nuciosa, resulta una alternativa terapéutica ideal en ciertos pacientes. La gran variabilidad de implantes dentales y alternativas de injertos óseos han resuelto el problema de sustituir una pieza dentaria perdida. En los pacientes en crecimiento o con potencial de crecimiento residual del proceso alveolar, se pone en evidencia el inconveniente que puede representar la colocación de implantes, lo que hace necesario ree-valuar la conservación de dientes y la utilización de técnicas quirúrgicas clásicas. Las tasas de éxito de los autotrasplantes autólogos han aumentado con el tiempo, alcanzando cifras mayores al 90%. En el pre-sente artículo se reporta un caso clínico de autotras-plante dentario con planificación digital y una réplica tridimensional de la pieza a trasplantar (AU)
Autologous tooth transplantation is defined as the positioning of an autologous tooth in a post-extraction socket or in a surgically formed bed. Currently, following the appropriate selection criteria and a meticulous surgical technique, it is an ideal therapeutic alternative in certain patients. The great variability of dental implants and bone graft alternatives have solved the problem of replacing a lost tooth. In growing patients or with potential for residual growth of the alveolar process, the inconvenience that implant placement can represent is evident, which makes it necessary to reevaluate tooth conservation and the use of classic surgical techniques. The success rates of autologous autologous transplants have increased over time, reaching figures greater than 90%. This article reports a clinical case of dental autotransplantation with digital planning and a three-dimensional replica of the piece to be transplanted (AU)

RESUMEN: Introducción: La utilización de instrumental piezoeléctrico en cirugía ortognática ha ido en aumento con el fin de minimizar el riesgo de daño a tejidos blandos en comparación al uso de sierra convencional. Sin embargo, aún existe incertidumbre respecto a las complicaciones asociadas a cada instrumental. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un meta análisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos cuatro revisiones sistemáticas que en conjunto incluyeron 10 estudios primarios, de los cuales, cuatro corresponden a ensayos aleatorizados. Concluimos que el uso de instrumental piezoeléctrico en comparación con la sierra convencional podría disminuir el riesgo de daño nervioso grave y disminuir el sangrado grave (>500 mL), pero la certeza de la evidencia es baja. Por otra parte, el uso de instrumental piezoeléctrico podría presentar poca o nula diferencia en el dolor postoperatorio, pero la certeza de la evidencia es baja. Finalmente no es posible establecer con claridad si el uso de instrumental piezoeléctrico disminuye la pérdida de sangre intraoperatoria (variable continua), la inflamación postoperatoria o el tiempo operatorio, ya que la certeza de la evidencia existente ha sido evaluada como muy baja.
ABSTRACT: Introduction: The use of piezoelectric bone surgery in orthognathic surgery has been increasing to minimize the risk of soft tissue damage compared to conventional saws. However, there is still uncertainty regarding the complications associated with each instrument. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed primary studies' data, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified four systematic reviews that included 10 primary studies, four of which corresponded to randomized trials. We conclude that the use of piezoelectric instrumentation compared to the conventional saw may reduce the risk of severe nerve damage and decrease severe bleeding (>500 mL), but the certainty of the evidence is low. On the other hand, the use of piezoelectric bone surgery may make little or no difference in postoperative pain, but the certainty of the evidence is low. Finally, we are uncertain whether piezoelectric bone surgery reduces intraoperative blood loss (continuous variable), postoperative inflammation, and operative time, as the certainty of the evidence has been assessed as very low.
