The assessment of adolescent hallux valgus before and after first metatarsal osteotomy

Summary A comprehensive method of evaluating the feet of patients with adolescent hallux valgus both before and after surgical correction is described. Serial clinical, photographic and radiological studies were made and a dynamic assessment of gait was carried out using a load-sensitive walkway. Observations were made on 36 feet in which hallux valgus was treated by a modification of the Wilson oblique metatarsal osteotomy, with removal of a wedge of bone and screw fixation. In the first six months after operation, there was a lateral shift of the weight-bearing pattern in the forefoot and less weight was taken on the toes, but there was a tendency to return to the pre-operative distribution of weight during the next four years. Persistence of the lateral shift of weight-bearing appeared to result from elevation of the first metatarsal head secondary to shortening of the first metatarsal during the osteotomy. This can be avoided by deliberate depression of the first metatarsal head at the time of operation and fixation of the fragments in the required position with a screw.

Résumé Les auteurs décrivent une méthode d'évaluation globale du pied, tant avant qu'après correction chirurgicale, chez des adolescents porteurs d'hallux valgus. Elle nécessite une série d'études des caractéristiques cliniques, photographiques et radiologiques, ainsi qu'une évaluation dynamique de la marche à l'aide d'un plateau de force. Cette méthode a été utilisée pour estimer avec exactitude les modifications survenues sur 36 pieds après que l'hallux valgus ait été traité par une variante de l'ostéotomie oblique du premier métatarsien décrite par Wilson, qui consiste en une résection d'un coin osseux suivie de fixation par une vis. Durant les six premiers mois post-opératoires, on note un déplacement de l'appui de l'avant-pied vers le dehors et une diminution de la charge au niveau des orteils, mais il y a une tendance à revenir à la répartition pré-opératoire de l'appui au cours des quatre années suivantes. La persistance du déplacement externe de l'appui semble résulter de la surélevation de la tête du premier métatarsien, conséquence du raccourcissement de cet os créé par l'ostéotomie. Ceci peut être évité en abaissant délibérément la première tête métatarsienne lors de l'opération et en fixant les fragments par une vis dans la position désirée.

     

The chevron osteotomy for correction of hallux valgus

Introduction The chevron osteotomy has become widely accepted for correction of mild and moderate hallux valgus deformities. The purpose of this study was to present the evolution of the chevron osteotomy at one institution over a period of 12 years. Methods Between April, 1991 and September, 1992, fifty-two consecutive patients with mild to moderate hallux valgus deformity underwent sixty-six distal chevron osteotomies at our institution. This was followed by 85 patients with 100 feet in the period from 1992 to 1995 and a group of 45 patients with 55 feet from 1994 to 1995. The final patient group included 61 patients with 89 feet operated from 2000 to 2002. Conclusion The chevron osteotomy is a reliable technique to correct hallux valgus deformities. Our recommendation after reviewing the results of the various modifications of the chevron technique revealed that the addition of a lateral release and a screw fixation will lead to the most reliable results.     

Lengthening scarf osteotomy for recurrent hallux valgus

BackgroundWe describe using the scarf osteotomy to correct a recurrent hallux valgus deformity and lengthen the shortened first metatarsal in symptomatic iatrogenic first brachymetatarsia.MethodsThirty-six lengthening scarf osteotomies were undertaken in 31 patients. Clinical and radiographic measures were taken pre and postoperatively.ResultsMean age at presentation was 53.4 years, and mean followup 3.9 years. The mean lengthening achieved was 4.9 mm. All osteotomies united with no complications. The mean IMA reduction was 4.0° (p < 0.001) and HVA 13.0° (p < 0.001). The mean AOFAS score increase was 33.8 (p < 0.001). There was a positive trend but no correlation (r = 0.28) between amount of metatarsal lengthening and AOFAS score change.ConclusionsWe describe the largest lengthening scarf osteotomy series for recurrent hallux valgus with iatrogenic first brachymetatarsia. The results suggest the procedure is successful, with a low complication rate. We anticipate that restoring first metatarsal length and alignment may reduce biomechanical transfer metatarsalgia over time.     

Outcome of the scarf osteotomy in adolescent hallux valgus

Purpose  We have reported the radiological and clinical outcome of scarf osteotomy in the treatment of moderate to severe hallux valgus among adolescent children. Method  Data were collected retrospectively between April 2001 and June 2006. The pre- and post-operative intermetatarsal angle (IMA), hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA) were determined. Patients were followed up for a mean of 37.6 months. Results  Thirteen patients with 19 operated feet were available at the time of the latest follow-up. There was significant improvement in the mean post-operative IMA, which was maintained to the last follow-up. There was statistically significant improvement in the 6-week post-operative HVA and DMAA. However, this was lost at the final follow-up. The mean American Orthopaedic Foot and Ankle Society score for the whole group was 80 (54–100). Conclusion  This study indicates that scarf osteotomy should be used with caution in symptomatic adolescent hallux valgus, as there is a high recurrence rate.     

Correction of hallux valgus deformity with distal soft tissue realignment and proximal metatarsal osteotomy

Abstract Fifty moderate to severe hallux valgus deformities were corrected with a distal soft tissue realignment and proximal crescentic metatarsal osteotomy. With an average follow-up of 5.6 years, 40 feet (80%) were pain free and 42 (84%) caused no functional limitation. The average hallux valgus angle improved from 38.2° preoperatively to 12.4° at follow-up. The average intermetatarsal angle improved from 15.4° to 6.8°. The arch of motion of the first metatarsophalangeal joint was 75° preoperatively and 62° at follow-up. According to the AOFAS scoring system, 29 results (58%) were excellent, 14 (28%) good, 2 (4%) fair and 5 (10%) poor. The 5 poor results were attributed to recurrence of hallux valgus (2 cases), stiffness (1), hallux varus (1) and malunion of the osteotomy in dorsiflexion (1). The incidences of hallux varus and malunion in dorsiflexion were 8% and 14%, respectively. This technique is valuable in correction of moderate to severe hallux valgus deformities.

拇趾外翻X线片观测指标及应用进展

X线测量是拇外翻畸形最重要的诊断和评价依据之一,选择正确的摄片方式和测量指标对拇外翻畸形的准确诊断和治疗方案的选择均有极其重要的意义。随着对拇外翻病因病理研究的深入,有关该病的X线测量方法和指标也日新月异。摄片的方法包括在负重与非负重状态下拍摄足的正位、侧位、斜位及籽骨轴位片。测量指标的选择也多种多样,包括角度测量、距离测量、籽骨位置的测量等,可作为术前畸形程度及术后疗效的评估。本文基于对国内外有关拇外翻X线测量的最新研究,对其测量方法及应用进行概述。
