Chevron截骨术治疗足拇外翻的疗效观察

目的探讨应用第一跖骨远端Chevron截骨术治疗轻度拇外翻的临床疗效。方法对13例22足轻度拇外翻患者采用第一跖骨远端Chevron截骨术进行治疗。患足术前术后摄负重正侧位X线片,进行AOFAS评分以评价功能和疼痛情况,并对结果进行统计学分析。结果所有患者均获得随访(平均11个月)。所有患者截骨端均达骨性愈合,平均临床愈合时间为6周。未出现血管、神经损伤或感染等并发症,至末次随访未出现一例内固定松动、断裂,拇外翻复发或第一跖骨头缺血坏死、转移性跖骨痛等并发症。术前HVA平均25.2°,术后为5.6°;术前IMA平均11.4°,术后为6.3°;术前AOFAS评分为52.4分,术后至末次随访时为87.5分。各项指标术前术后对比差异均有统计学意义(P<0.01)。结论第一跖骨远端Chevron截骨术治疗轻度拇外翻,近期疗效满意。     

Long-term follow-up of the Green-Watermann osteotomy for hallux limitus

The authors undertook a retrospective analysis of the long-term efficacy of the Green-Watermann procedure for the treatment of painful hallux limitus or rigidus. Questionnaires were sent to 80 consecutive patients who had such procedures performed between 1990 and 1999. Medical records and radiographs were reviewed for the 32 patients who completed the questionnaires, representing 40 Green-Watermann procedures. Twenty-four patients were able to return for clinical evaluation. The average length of follow-up was 4 years (range, 1 to 10 years). The questionnaires addressed pain before and after surgery, function after surgery, complications, and overall impression and satisfaction. Nearly all of the patients (30 of 32; 94%) reported that surgery had significantly relieved their hallux joint pain, and a slightly smaller proportion (28 of 32; 88%) felt that their chief complaints were at least 70% improved. Clinical evaluation revealed adequate range of motion at the first metatarsophalangeal joint. It is concluded that the Green-Watermann procedure is an effective treatment approach for hallux limitus and rigidus, resulting in a significant reduction in pain, an increase in function, and a high degree of patient satisfaction.     

Proximal oblique crescentic osteotomy in hallux valgus

Twenty-six patients with moderate-to-severe hallux valgus deformities were evaluated before and after treatment. All of the patients had incongruent great toe joints. The patients underwent modified proximal crescentic osteotomy, which was termed proximal oblique crescentic osteotomy. The results were evaluated at an average follow-up time of 55 weeks. Objective criteria were hallux valgus angle, intermetatarsal angle, shortening of the first metatarsal, and angulation at the osteotomy site. Clinical evaluation was made according to the rating system of the American Orthopaedic Foot and Ankle Society. The mean correction of the hallux valgus and intermetatarsal angles was 22.1 degrees and 9.9 degrees, respectively. Short-term results indicate that proximal oblique crescentic osteotomy is effective in the treatment of hallux valgus; its advantages over other procedures include its technical ease and low rate of complications.     

拇外翻Scarf截骨术的发展与展望

<正>拇外翻在前足冠状面、水平面、矢状面均存在畸形,是前足最常见的畸形之一,目前矫正这种畸形的术式较多,其中Scarf截骨术是临床运用最广泛的术式之一[1],该术式具备三维矫形功能[2],能矫正中、重度拇外翻。Scarf截骨术由Meyer提出,后逐渐在临床上推广[3-6]。传统Scarf截骨术存在矫形力不足、转移性跖痛等并发症,因此相关学者在传统Scarf截骨术的基础上不断进行改良,以期达到最佳疗效。

第一跖趾关节金属半关节置换结合跖骨截骨治疗进展期拇僵直伴拇外翻

Hallux rigidus occurs mainly at the first metatarsophalangeal （MTP） joint,causing localized pain and degenerative arthritis.1 This condition frequently occurs together with hallux valgus and is difficult to treat.For hallux rigidus affecting only one joint,the treatment choices include articular debridement,resection arthroplasty,prosthetic arthroplasty,and arthrodesis,depending on the degree of arthritis.     

Stress fractures of the lesser metatarsals after a Wilson osteotomy for correction of hallux valgus deformity

This article describes a patient with lesser-metatarsal stress fractures resulting from an oblique Wilson displacement first metatarsal osteotomy. The shortening of the first metatarsal forces the lesser metatarsals to bear the weight previously borne by the first ray and increases the compression stress on the adjacent metatarsal heads. The proximal displacement of the osteotomy must be minimized in order to limit the risk of stress fracture of the lesser metatarsals.     

第一跖骨近端截骨术治疗踇外翻

本院１９８９～１９９４年共施行７０例　外翻矫形手术。其中２１例（４０足）行张开式第一跖骨近端截骨术治疗，经过１年４个月～５年（平均３年）的随访，取得了满意的疗效，优良率为９０．５％。此术式是软组织联合骨性手术，因而术后其跖骨角、踇外翻角、足外形等方面矫形效果确实、可靠。     

Pseudarthrosis after percutaneous distal osteotomy in hallux valgus surgery: a case report

Nonunion of the first metatarsal after hallux valgus surgery is a rare complication that often results in significant pain and disability requiring surgical management. We report the case of a 42-year-old woman who developed a pseudarthrosis of the first metatarsal after percutaneous retrocapital distal osteotomy of the first metatarsal for a mild hallux valgus deformity. The operative treatment consisted of debridement of fibrous nonunion with plating followed by application of pulsed electromagnetic fields (PEMF) with an external device.

Cheilectomy for hallux rigidus

Cheilectomy is the excision of an irregular osseous rim that interferes with joint motion. Twenty cases of hallux rigidus/limitus treated by cheilectomy have been reviewed 18 months after surgery. A satisfactory outcome was achieved in all but 2 cases, which were failures. Range of joint motion, in particular dorsi flexion, improved in all but 6 cases. Cheilectomy is a simple and effective alternative to arthrodesis in the treatment of hallux rigidus.
