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.     

籽骨系统与拇外翻

籽骨系统包括胫腓侧籽骨及相关肌肉韧带,其中拇短屈肌、拇收肌、拇展肌在籽骨系统生物力学平衡中发挥着重要作用.籽骨的各种病理变化如籽骨骨髓炎、籽骨骨折、多分籽骨、籽骨骨膜外软骨瘤与拇外翻的发生可能具有一定关系.籽骨脱位和半脱位在拇外翻发生发展机制中占据重要地位,其影像学分级系统被部分学者用于拇外翻术前诊断和术后预后的评估,但至今仍不为大多数骨科医生所熟识.基于X线前后位片的籽骨分级系统,测量的精确性受到质疑,而籽骨轴位片同样可能存在误差,至今仍没有一种完善的籽骨脱位和半脱位测量的影像学技术.籽骨旋转角和MRI评估籽骨系统是近年来新的尝试.     

Basal cell carcinoma masquerading as a hallux valgus

The incidence of primary skin cancers of the foot is exceedingly low; conversely, problems associated with a hallux valgus are common. A nonhealing ulcer overlying a hallux valgus managed conservatively with ointments and orthotic adjustments, and even with skin grafts, did not resolve over a period of 10 years. Ultimately, a shave biopsy revealed that the lesion was a basal cell carcinoma. Wide local excision and another skin graft resulted in tumour eradication and, finally, healing. Basal cell carcinoma associated with a hallux valgus has not been previously reported, and this reinforces the concept that malignant degeneration as the cause of any chronic ulceration should not be overlooked.     

Hallux valgus angle as main predictor for correction of hallux valgus

Background  

It is recognized that different types of hallux valgus exist. Classification occurs with radiographic and clinical parameters. Severity of different parameters is used in algorithms to choose between different surgical procedures. Because there is no consensus about each parameter nor their cut-off point we conducted this study to analyze the influence of these variables on the postoperative hallux valgus angle.

Giant cell tumor of the EDL tendon sheath: an unusual cause of hallux valgus

Hallux valgus is a lateral deviation of the proximal phalanx of the first metatarsophalangeal joint. It is a common disorder in adults. The etiologic factors include modern shoes, rheumatoid arthritis, pes planus, metatarsus primus varus, and trauma. Tumors causing hallux valgus deformities are unusual. We report a 50-year-old female with a hallux valgus deformity caused by a giant cell tumor of the second EDL tendon sheath. Surgical excision of the tumor and corrective osteotomy produced a permanent cure. This unusual cause of a hallux valgus deformity should increase awareness of tumors as a possible cause of foot deformities.     

Intermetatarsal osteodesis: a fresh approach to hallux valgus

This paper covers 10 years of experience with intermetatarsal osteodesis for the correction of the hallux valgus complex. The results are good or excellent in 95.2% of cases and patient satisfaction corresponds to this finding. The procedure presented addresses all aspects of the deformity while remaining technically undemanding. It is also non-destructive, preserving all tissues for any future salvage procedure. The authors recommend this operation in hallux valgus when the metatarsophalangeal joint is preserved.
