Keller手术治疗拇外翻疗效分析

目的观察Keller手术治疗     

The use of footprints in assessing the results of operations for hallux valgus. A comparison of Keller's operation and arthrodesis.

One hundred and seventy feet have been reviewed after operations for hallux valgus; eighty-five had had arthrodesis of the first metatarso-phalangeal joint and eighty-five had had Keller's operation. Footprints were made in order to assess the patterns of weight-bearing on the big toe and on the lesser metatarsal heads. After arthodesis the big toe bore weight in 80 per cent compared with 40 per cent after Keller's operation. The ability to bear weight on the big toe is related to the presence of metatarsalgia and excessive weight-bearing on the lesser metatarsal heads. These complicaitons were seen more commonly after Keller's operation (particularly when more than one-third of the phalanx had been excised) than after arthrodesis.     

Forces under the hallux valgus foot before and after surgery.

Abnormalities in the hallux valgus foot and changes after surgery were investigated by measuring the distribuiion of load on the foot in walking. Hallux valgus was associated with reduced load imposed on the toes, and on the medial side of the forefoot, compared with a large sample of healthy feet. Abnormalities correlated with the degree of the deformity. Both Keller's operation and a wedge displacement osteotomy of the first metatarsal not only failed to restore normal loading but increased the abnormalities of loading seen preoperatively. A large decrease in the angle between first and second metatarsals as a result of surgery minimized this increase. A silastic arthroplasty did not carry high loads when used to treat hallux valgus, but near normal loads were imposed on it when used for hallux rigidus. Considerable variability was found in the loading distribution on the healthy feet. The distribution between first and second metatarsal heads was partially dependent upon their protrusions, relative to the direction of walking. The changes in the relationships between the loadings on the forefoot and skeletal shape in response to surgical operations are important for our understanding of treatment of the hallux valgus foot.     

The management of the painful first metatarsophalangeal joint in the older patient. Arthrodesis or Keller's arthroplasty?

We report a prospective randomised trial comparing Keller's arthroplasty and arthrodesis of the first metatarsophalangeal joint for the management of symptomatic hallux valgus and hallux rigidus in the older patient. In 81 patients (110 feet), with a minimum of two years follow-up, both procedures gave a similar degree of patient satisfaction and symptom relief. The incidence of metatarsalgia was also similar. As there were no obvious advantages to arthrodesis, and since six out of 50 arthrodesed toes required revision, we suggest that Keller's arthroplasty is the better operation in these patients.     

The long-term results of resection arthroplasties of the first metatarsophalangeal joint in rheumatoid arthritis

We performed a retrospective study in 188 patients (254 feet) with rheumatoid arthritis and compared the late results of Keller's procedure with those of Hueter-Mayo's technique after 7.9 years. More than 60% of the Keller group and 30% of the Hueter-Mayo group were suffering from persistent metatarsalgia due to increased forefoot pressure as well as experiencing pain around the great toe. Plantar callosities, recurrent hallux valgus deformity, lack of plantar flexion and weakened push-off were more frequent after Keller's procedure.     

Proximal spherical metatarsal osteotomy for the foot with severe hallux valgus

BACKGROUND: A proximal spherical metatarsal osteotomy was devised to correct not only varus deviation of the first metatarsal, but also dorsiflexion. We expected to increase the medial longitudinal arch by adding plantar flexion at the osteotomy site. To investigate the limitations of this procedure for feet with severe hallux valgus, a followup study was performed on patients with preoperative hallux valgus angles greater than or equal to 40 degrees. MATERIALS AND METHODS: Forty-eight feet in 37 patients (10 male, 27 female) (60 years; range, 20 to 84 years) were investigated. Mean followup was 4 years and 1 month, ranging from 2 to 8 years. The spherical osteotomy was performed using a curved chisel. A distal soft tissue procedure was done at the same time. Twenty feet received combined operations for their combined deformities. RESULTS: While 81% of patients were satisfied with the results, 50% of those with preoperative hallux valgus angles greater than or equal to 50 degrees had postoperative hallux valgus angle greater than or equal to 20 degrees. In these patients, correction of metatarsus primus varus was good, but correction of valgus deviation of the hallux was fair. Mean correction toward plantar flexion was 1.5 degrees and no increase in arch height was achieved. CONCLUSION: The proximal spherical osteotomy could consistently achieve satisfactory results for the patients with hallux valgus angles less than 50 degrees. However, the corrections were worse in feet with more severe deformities. Furthermore, plantarflexion at the osteotomy site was offset by displacement at the first tarsometatarsal joint. If plantarflexion is indispensable, arthrodesis of the tarsometatarsal joint is recommended.     

Akin截骨术在拇外翻手术应用的探讨

背景：Akin截骨术能够纠正拇外翻手术中残留拇趾畸形但也存在并发症,总结探讨在拇外翻手术时联合应用Akin截骨治疗拇外翻的临床疗效并探讨使用指征。 方法：总结分析2006年10月至2010年10月,在拇外翻手术时联合应用Akin截骨术48足,软组织手术加Akin截骨术6足,chevon截骨术加Akin截骨术29足,跖骨基底截骨加Akin截骨术8足,第一跖楔关节融合加Akin截骨术5足。 结果：所有病例均获得随访,随访时间6个月至5年,平均30．3个月,未见拇外翻复发病例。术前拇外翻角为37．2°±8．9°,IMA为16．5°±6．7°;术后拇外翻角为13±6．8°,IMA为8．9°．±4．5°。术前AOFAS评分为（43±10．5）分,术后为（84±7．8）分,具有统计学意义。 结论：在拇外翻手术时,根据趾骨畸形情况联合应用Akin截骨术可以降低拇外翻手术复发率,临床效果确切,但需要严格掌握手术适应证。     

Scarf osteotomy in hallux valgus: a review of 72 cases

The Scarf osteotomy is now widely used for the correction of hallux valgus. The aim of our study was to evaluate the results after Scarf osteotomy considering patient's satisfaction as well as the clinical and radiological results. Between 1996 and 1999, 72 feet underwent a Scarf osteotomy of the first metatarsal and, in 11 feet, an additional Akin osteotomy of the proximal phalanx, for the correction of hallux valgus (55 patients: 49 female, 6 male; mean age: 52 years). The hallux valgus angle improved significantly, from 32 degrees preoperatively to 18 degrees at follow-up (minimal follow-up: 6 years; mean: 7.5 years). A second operation was necessary in two patients because of recurrence of hallux valgus, and a fusion of the first metatarsophalangeal joint was performed in two patients. At the time of latest follow-up 78% of the patients were satisfied or very satisfied with the result. The Scarf osteotomy combined with Akin's closing wedge osteotomy is a safe and effective procedure for the treatment of moderate hallux valgus deformities.

Hallux Valgus With Second Brachymetatarsia Discovered Accidentally: A Case Report

Hallux valgus deformity is one of the most common foot and ankle diseases, while brachymetatarsia is a rare foot anomaly with pathological shortening of a metatarsal bone. We present a case of hallux valgus deformity possibly due to second brachymetatarsia. As the hallux valgus was associated with dorsal dislocation of the second toe that made it difficult to evaluate the length of the second toe, the patient was unaware of the second metatarsal shortening until the lengths of the toes compared by manual reposition of the second MTP joint. In this case, proximal osteotomy of the first metatarsal on the hallux valgus and single-stage bone lengthening of the second metatarsal with iliac bone grafting on the second brachymetatarsia were performed. One year after the operation, the callosity of the third toe resolved and the clinical scores were improved. In the case of a hallux valgus deformity with second dorsal dislocation of the toes, surgeons should consider that there are rare cases with second metatarsal shortening. When hallux valgus associated with second brachymetatarsia is diagnosed, second metatarsal lengthening should be considered in addition to hallux valgus surgery.
