ABSTRACT
Objective:To explore the clinical efficacy of reconstructing the calcaneocuboid and calcaneonavicular ligaments with the autologous semitendinosus for chronic bifurcate ligament injury.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with chronic bifurcate ligament injury who had been treated by anatomical reconstruction with the autologous semitendinosus from March 2018 to January 2021 at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan. There were 4 males and 8 females with an age of (41.4±9.6) years. Seven left and 5 right feet were affected; the time from injury to surgery was (9.3±4.3) months. The surgical efficacy was evaluated based on anteroposterior and lateral imaging assessments of foot weight-bearing at 6 months postoperation, comparison of the visual analogue scale (VAS) pain scores for foot weight-bearing walking and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scores between preoperation and the last follow-up, stress test for stability of the transverse tarsal joint, recovery of movement, and occurrence of complications.Results:All patients were followed up for (18.4±4.0) months. Their sports activities were completely resumed after postoperative (6.8±3.9) months. Primary wound healing was achieved in all patients. One patient suffered from cutaneous nerve lesion and skin numbness, the symptoms of which disappeared after conservative treatment. Double harmonic curves were observed on the anteroposterior and lateral imaging films of foot weight-bearing in all patients. The spaces in the calcaneocuboid and the calcaneonavicular joints were normal, the articular positions were matched, and the calcaneocuboid joint was stable without recurrence or worsening of displacement. The VAS decreased significantly from preoperative 6.5 (5.6, 7.0) to 0.0 (0.0, 1.0) at the last follow-up, and the AOFAS mid-foot score increased significantly from preoperative (55.6±8.8) points to (92.3±2.6) points at the last follow-up ( P<0.05). The stress test for the stability of the transverse tarsal joint showed joint stability. Conclusion:Reconstruction of the calcaneocuboid and calcaneonavicular ligaments using the autologous semitendinosus is an alternative treatment for patients with chronic bifurcate ligament injury, because it can restore the stability of the bifurcate ligament and obviously improve the foot and ankle functions with limited postoperative complications.

Objective To evaluate distractor-assisted reduction for Lisfranc injury complicated with compressive fracture of lateral foot column.Methods A retrospective study was conducted of the 18 patients who had been treated surgically at Department of Foot and Ankle Surgery,Zhengzhou Orthopaedics Hospital between May 2014 and March 2017 for Lisfranc injury complicated with compressive fracture of lateral foot column.They were 10 males and 8 females,with an average age of 38.4 years (from 25 to 65 years).The injury involved the right foot in 11 cases and the left foot in 7.Their concomitant injuries were 12 compressive cuboid fractures and 6 compressive fractures of the calcaneal anterior process.According to the Chiodo-Myerson classification,there were 13 cases of three-column injury,3 ones of middle-lateral column injury and 2 ones of medial-lateral column injury.All the injuries were closed.After the condition of foot soft tissues permitted,open reduction assisted by a distractor and internal fixation with a mini locking plate was performed.Functional outcomes were assessed according to the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle scores and visual analogue scale (VAS) at the final follow-ups and complications during follow-up.Results The 18 patients were followed up for one to 4 years (average,2 years).Their AOFAS hindfoot-ankle scores ranged from 55 to 96 points (average,80.4 points);their VAS ranged from 0 to 6 points (average,1.5 points).Radiographic evidence of degeneration was noted in 10 patients.Of them,2 reported persistent pain which was cured by arthrodesis after conservative therapy failed and one presented with symptoms of injury to sural and cutaneous nerves which disappeared after oral administration of neurotrophic drugs for half a year.No such complication as skin necrosis,infection or implant failure occurred in other patients.Conclusion Open distractor-assisted reduction and internal fixation of lateral foot column with a mini locking plate,combined with bone graft if necessary,is an effective treatment for Lisfranc injury complicated with compressive fracture of lateral foot column,because it can effectively restore the alignment of lateral column and result in satisfactory therapeutic effects.
ABSTRACT
Charcot foot is a rare disease in clinic, its pathogenesis includes neurotrauma theory, neurovascular theory, comprehensive theory, and inflammatory factor theory. The disease is characterized by progressive joint and bone destruction of foot and ankle joint. Conventional X-ray examination is not sensitive to the early diagnosis of disease, the manifestation of CT and MRI of disease is characteristic and could be used to make a comprehensive evaluation of bone and soft tissue lesions of disease. It is not difficult to make a diagnosis based on characteristic findings of CT and MRI and clinical manifestations such as swelling, pain and skin temperature rising of foot and ankle. Charcot foot has multiple classification methods including anatomy, imaging and clinical classification. Improved Eichenholtz staging classification is most commonly used currently which could make a more comprehensive assessment of disease and guide treatment better. According to the stage of disease, treatment could be carried out including non-weight bearing and brace protection, drugs therapy and surgical treatment, etc. Early diagnosis, brace protection, could protect joint and delaying progression of deformity. There is no clear long-term and generally accepted conclusion about the efficacy of drug therapy. For advanced patients, surgical treatment must be actively performed to preserve a stable and functional ankle joint and reduce amputation rate.

ABSTRACT
Objective To evaluate the foot function after Lisfranc injury with local soft tissue in-jury. Methods From November 2000 to April 2006, 43 patients (at mean age of 32 years) with fresh Lisfranc injuries (45 sides) were managed with open reduction and internal fixation with screws, Kir-schner wires and AO plates. All patients had no joint surface damage and received no fusion surgery. Ac-cording to the Quenu-Kuss classification of Lisfranc injury, there were 14 patients with type-A injury, 21 with type-B and 10 with type-C. According to AO classification, there were 29 feet without severe soft tis-sue injury and 16 feet with severe soft tissue injury, of which 10 patients were combined with severe local soft tissue injury (one patient with Foot compartment syndrome). The period from injury to surgery was seven days. All patients received cast immobilization for 8-12 weeks and the foot function was evaluated by anteroposterior and lateral X-rays and American Orthopedic Foot and Ankle Society (AOFAS) score. Results All patients were followed up for 12-69 months (average 37 months), which showed that all pa-tients obtained anatomic reduction and 32 patients were satisfied with operative outcome. The average postoperative AOFAS score was 97 points for patients without severe soft tissue injury and 82 points for pa-tients with severe soft tissue injury (P<0.05). Conclusion After Lisfranc injury, the foot function is related to severity of both joint injury and local soft tissue injury.
ABSTRACT
Objective To evaluate the surgical characteristics and clinical effect of percutaneous reduction with kirachner wire assisted by a small lateral incision approach for poking reduction and allngraft bone transplantation in treating compressive intra-articular calcaneal fractures. Methods A retrospective analysis was performed among 17 patients with compressive intra-articular calcaneal fractures (Sanders Ⅱ to Ⅲ ) treated by percutaneous reduction with kirachner wire assisted by a small lateral incision approach for poking reduction and allograft bone transplanta-tion. Results All the patients were followed-up for an average time of 13.5 months. The wound of 15 feet achieved primary healing, the acute rejection was found in 2 patients. The Bohler's angle was (9.58±5.25)° and Gissane an-gle was (101.15±13.83)° preoperation and was (33.55±4.17)° and (113.25±12.17)° immediate postopera-tion, showing statistically significant differences pre-and postoperation(P < 0.05). By the lately follow-up, the Bohler angle was (31.65±7.72)° and Gissane angle was (111.15±8.68)°, also showing statistically significant differ-ences when compared to preoperation (P < 0.05), there was no statistically significant differences (P > 0.05) when compared with normal X-ray. Conclusion That percutaneous reduction with kirschner wire assisted by a small lateral incision approach for poking reduction and allograft bone transplantation in treating the compressive intra-articular cal-caneal fractures (Sanders Ⅱ to Ⅲ) is minimally invasive, less complication, and it enables satisfactory recoastruc-tion of bone defects and allows metanatomic reduction and functional recovery, also maintaining restoration of calcane-al height and anatomic reduction of the posterior facet.

OBJETIVO: Este trabalho teve como objetivo estimar as forças plantares nos dedos dos pés de mulheres com hálux valgo e/ou pés planos. MÉTODOS: Trata-se de um estudo transversal envolvendo mulheres com hálux valgo e/ou pés planos confirmado através de análise radiográfica. Mediram-se as forças plantares, utilizando plataformas de forças. Coletaram-se estas forças com as mulheres descalças e em posição ereta, por três medidas sendo obtida uma média. Os dados foram adquiridos através da ponte amplificadora Spider 8 da HBM e analisados através do programa Catman®. Obtiveram-se as medidas de forças dos dedos de ambos os pés e as médias foram comparadas pelo teste t de Student segundo a presença de hálux valgo e pés planos; a associação entre essas deformidades foi estimada pelo teste exato de Fischer bicaudal, a significância estatística adotada foi alfa = 5 por cento. RESULTADOS: Foram incluídas no estudo, vinte mulheres com presença ou não de hálux valgo. As forças médias encontradas mostraram-se maiores no 5º dedo em relação ao 1º dedo de ambos os pés (p< 0,05) em ambas as situações. CONCLUSÃO: Neste estudo encontraram-se, ao contrário de outros trabalhos, forças no 5º dedo maiores que no 1º em ambos os pés.
OBJECTIVE: to measure the plantar forces above the toes of women with hallux valgus and/or flat feet. METHODS: This study involved women with hallux valgus and/or flat feet confirmed by X-ray images. The plantar forces were measured utilizing force plates. Force was measured three times, which were taken with the women on barefoot and at upright position, recording the average for the three measurements. Data were acquired from Spider 8 system (HBM) and analyzed by using a Catman® software. The measurements for both feet's toes force were reported and the averages were compared by the Student's t-test according to the presence of hallux valgus and flat feet; the association between these deformities was estimated by using the two-tailed Fischer's exact test, the statistical significance adopted was alpha = 5 percent. RESULTS: For this study, 20 women with or without hallux valgus were included. The mean force values found showed to be higher on the fifth toe compared to first toe of both feet (p < 0.05) in both situations. CONCLUSION: in this study, we found strong forces on the fifth toe than on the first toe, contradicting some studies in literature.
