The American Orthopaedic Foot and Ankle Society score and weight-bearing radiographs of the foot were applied to assess the feet pre- and postoperatively with a mean duration of follow-up of （38.2±3.2） months. The surgical procedure includes the release of the distal soft tissues, excision of the medial eminence, plication of the medial part of the capsule, and transfer of the EHL tendon, and reconstructing its insertion.Results At follow-up, 35 feet （23 patients, 85%） were free from pain at the first metatarsophalangeal （MTP） joint. In three feet （two patients）, the pain was alleviated but persisted. The mean hallux valgus angle decreased significantly from a preoperative 38.3°±8.0° to 7.3°±2.0° at the time of the most recent follow-up （P 〈0.0001）, and the mean intermetatarsal （IM） angle decreased significantly from preoperative 12.5°±3.4° to postoperative 6.5°±2.4° （P 〈0.0001）. The mean score according to the American Orthopaedic Foot and Ankle Society had increased from 46.5 to 84.8 points （P 〈0.0001）.Conclusions Hallux valgus can be corrected by transferring the EHL tendon medially and reconstructing its insertion.The technique can achieve stress balance of metatarsophalangeal joints and therefore prevent the recurrence of hallux valgus.展开更多

Transfer of the anterior tibialis tendon (ATT) to the lateral cuneiform is an effective method for correcting this deformity when the cuneiform is ossified in children who are 3 to 5 years of age. We describe two cases of a previously unreported method of ATT transposition for correction of bilateral residual dynamic supination in a 26-month-old and a 19-month-old patient. Both patients presented shortly after birth with bilateral congenital idiopathic clubfoot and were initially treated with the Ponseti method. Both had residual deformity following initial treatment that included posterior contracture and metatarsus adductus with dynamic forefoot supination. This was surgically corrected with a posterior release and medial release of the 1st metatarsal/1st cuneiform joint. To correct dynamic supination, the ATT was transplanted laterally into the released midfoot joint. These two patients were followed post-operatively for 7.5 years and have correction of their residual deformity in both feet based on subjective functioning, appearance, range of motion, strength, and gait. Both have excellent lateral pull of their ATT, which functions as a strong foot dorsiflexor. No residual supination is present. This is the first report of lateral transposition of the ATT as an interposition graft at the released 1st metatarsal/1st cuneiform joint in patients with relapsed clubfoot. We suggest that this method should provide a high level of functioning in children with relapsed supination deformity and whose 3rd cuneiform has not yet ossified.展开更多

These ruptures can occur after a fracture. Aim: We report a case of spontaneous rupture of extensor pollicis longus tendon, and describe the treatment. Case presentation: We report the case of a 63-year-old woman who had extensor pollicis longus tendon rupture after non-displaced extra-articular distal radius fracture, treated by wrist circular cast immobilization. Extensor indicis proprius tendon transfer was performed, with an excellent functional result. Conclusion: Extensor pollicis longus tendon rupture can occur after non-displaced extra-articular distal radius fracture. Its treatment by tendon transfer helps to restore function of hand.展开更多

Multiple surgical options like muscle release, tendon transfer, or humeral osteotomy are available to treat such cases. Purpose:?Evaluation of the outcome of subscapularis release and latissimus dorsi and teres major tendon transfer in the management of obstetric brachial palsies in Mansoura University neurosurgical department. Study type: Retrospective observational study. Patients and Methods: Twenty-five cases who underwent subscapularis release and latissimus dorsi and teres major transfer were included in the study. All patients were subjected to complete history taking, through clinical examination. The degree of shoulder movement and disability was assessed via Modified Gilbert shoulder evaluation scale. Results: The least follow up period for our patients was 9 months. There was a clear improvement of shoulder function evaluated using Modified Gilbert shoulder evaluation scale as there were 73% of postoperative group between GIV and GV while about 84% of preoperative group were between GII and GIII. Conclusion: Tendon transfer is a valid easy procedure for correction of shoulder deformities in patients with obstetrical brachial plexus palsy. It is considered a very good option for patients who missed the chance of microsurgical repair or patients with poor shoulder recovery after surgery. Although some authors reported deterioration of shoulder function with log time follow up after tendon transfer, it is still better than those who were not operated.展开更多

文摘Fracture of an ossification of the Achilles tendon(OAT)is a rare entity,and its etiology,pathology,and treatment remain unclear.We reviewed and scrutinized 18 cases(16 articles)of the fracture of an OAT.The most common etiologies of the ossifications include previous surgery and trauma.The fractures often occur without any trigger or with minimal trigger.The long,>5 cm,ossification in the body of the Achilles tendon may have a higher risk of fracture.The OAT itself is often asymptomatic;however,its fracture causes severe local pain,swelling,and weakness of plantar flexion,which forces patients to undergo aggressive treatments.Regarding the treatments of the fractures,nonoperative treatment by immobilizing ankle joint could be an option for elderly patients.However,because it often cannot produce satisfactory results in younger patients,surgical treatment is typically recommended.Excision of the fractured mass and repairing the tendon is applicable if the remnant is enough.If there is a defect after the excision,reconstruction with autologous grafts or adjacent tendon transfer is performed.Gastrocnemius fascia turndown flap,hamstring tendon and tensor fascia lata are used as autologous grafts,whereas peroneus brevis and flexor hallucis longus tendons are used for the tendon transfer.If the fracture of an OAT is treated properly,the functional result will be satisfactory.
文摘Dynamic supination of the foot is a common residual deformity in children with clubfeet treated with the Ponseti method. Transfer of the anterior tibialis tendon (ATT) to the lateral cuneiform is an effective method for correcting this deformity when the cuneiform is ossified in children who are 3 to 5 years of age. We describe two cases of a previously unreported method of ATT transposition for correction of bilateral residual dynamic supination in a 26-month-old and a 19-month-old patient. Both patients presented shortly after birth with bilateral congenital idiopathic clubfoot and were initially treated with the Ponseti method. Both had residual deformity following initial treatment that included posterior contracture and metatarsus adductus with dynamic forefoot supination. This was surgically corrected with a posterior release and medial release of the 1st metatarsal/1st cuneiform joint.

These two patients were followed post-operatively for 7.5 years and have correction of their residual deformity in both feet based on subjective functioning, appearance, range of motion, strength, and gait. Both have excellent lateral pull of their ATT, which functions as a strong foot dorsiflexor. No residual supination is present. This is the first report of lateral transposition of the ATT as an interposition graft at the released 1st metatarsal/1st cuneiform joint in patients with relapsed clubfoot. We suggest that this method should provide a high level of functioning in children with relapsed supination deformity and whose 3rd cuneiform has not yet ossified.
