Mid-term results of Scarf osteotomy in hallux valgus

We performed a retrospective study on 178 Scarf osteotomies with a mean follow-up of 44.9 months (range 15–83 months). Clinical rating was based on the forefoot score of the American Orthopaedic Foot and Ankle Society (AOFAS). Weight bearing X-rays were used to perform angular measurements and assess the first metatarsophalangeal joint (MTP 1). At follow-up the mean AOFAS score had improved significantly (p < 0.001), but only 55% of the feet showed a perfect realignment of the first ray. Patients with a hallux valgus angle exceeding 30° and pre-existing degenerative changes at the MTP 1 joint displayed inferior clinical results (p < 0.05). Nearly 20% of the patients suffered from pain at the MTP 1 joint. This was clearly attributed to an onset or worsening of distinct radiographic signs of arthritis (p < 0.05) resulting in painfully decreased joint motion. Comparing radiographic appearance three months postoperatively and at follow-up, we found that radiographic criteria (hallux valgus, first intermetatarsal angle, hallux valgus interphalangeus, MTP 1 joint congruency, arthritic lesions at MTP 1) worsened with time.     

Scarf osteotomy for hallux valgus repair: the dark side

HYPOTHESIS/PURPOSE: The Scarf osteotomy has gained popularity as treatment of choice in parts of Europe and is based on sound structural principles. The excellent results reported by others could not, however, be reproduced by the author and the results are presented. METHODS: From January 1997 to June 1997 the Scarf osteotomy was selected in 20 consecutive patients (12 female and eight male patients, ages 18 to 60, mean: 41 years) with moderate metatarsus primus varus (IMA 13 to 20 degrees) and hallux valgus deformities (less than 40 degrees). The AOFAS Hallux Metatarsophalangeal-Interphalangeal Scale, visual analog scale and patient satisfaction were monitored prior to surgery, six and 12 months post-op. The patients were treated in a short leg cast, non-WB for two weeks followed by four weeks partial WB in a cast shoe. Routine post-bunion rehabilitation followed once the radiological and clinical diagnosis of healing was made. RESULTS: Multiple complications were encountered. The most common was "troughing" of the metatarsal with loss of height. This occurred in seven patients (35%). Other complications include delayed union (5%), rotational malunion (30%), proximal fracture (10%), infection (5%) and early recurrence of deformity in 25%. All 20 patients were available for follow-up at six months, and 19 of 20 at 12 months. The AOFAS score pre-op was a mean of 53. At six months a mean of 54 (19 to 69) and at 12 months 62 (24-100). Forty-five percent (9/20) were unsatisfied at one year and would not recommend the surgery to a friend. CONCLUSIONS/SIGNIFICANCE: The Scarf osteotomy has multiple potential pitfalls and should probably be reserved for moderate bunions in young people with good bone quality. There are multiple potential problems and the salvage of a failed Scarf osteotomy is difficult.     

Scarf osteotomy in the management of symptomatic adolescent hallux valgus

Purpose  

This study was designed to assess the utility of the scarf osteotomy in the management of symptomatic adolescent hallux valgus.     

Scarf versus proximal closing wedge osteotomy in hallux valgus treatment

Aim  The aim of this study was to evaluate the distal metatarsal articular angle as a key factor in choosing between the proximal closing wedge osteotomy and scarf osteotomy. Method  The investigation involved 40 feet: 32 females aged 13–68 in whom 24 unilateral and 8 bilateral operations had been performed from 24 to 63 months previously. Results  There were statistically significant differences between groups in the postoperative hallux valgus angle and in first metatarsal shortening. We found an inverse correlation between the preoperative distal metatarsal articular angle and intermetatarsal angle improvement after proximal closing wedge osteotomy and a positive correlation after scarf osteotomy. Conclusion  This study confirmed the value of distal metatarsal articular angle assessment.     

Scarf osteotomy for hallux valgus—is an Akin osteotomy necessary?

Scarf osteotomy has gained popularity as one of the recommended procedures for moderate to severe hallux valgus. An Akin osteotomy may also allow additional correction but carries its own complications. The aim of this study was to assess the need for Akin osteotomy with a scarf procedure.We reviewed our results of scarf osteotomy with and without Akin in 69 patients with 99 procedures. Sixteen patients (25 feet) had an Akin osteotomy with a scarf procedure. Radiological results were analysed by measuring the hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA) and the position of the tibial sesamoid. AOFAS scores were collected prospectively. Patient satisfaction was determined by whether or not they would have the operation again for a similar condition.The mean age of the patients was 48.3 years (range 12–76) with a mean follow-up of 21 months. The mean improvement for the whole group in the IMA was from 15.8 to 7.9, HVA from 37.9 to 16.4 and DMAA from 19 to 9.9 was noted. The position of sesamoids improved from a mean of 5.8 to 2.3. The results were similar in both the groups and no significant difference was noted. AOFAS score improved from a mean of 53.6 preoperatively to 92.5 postoperatively. Three patients in the scarf group needed an Akin osteotomy as a revision procedure.Scarf osteotomy alone may be an effective procedure for moderate to severe hallux valgus. An Akin osteotomy may be indicated if residual hallux valgus is noted during surgery.     

Scarf osteotomy without internal fixation for correction of hallux valgus: A clinical and radiographic review of 148 cases

Background

Hallux valgus is a common condition with in excess of 120 procedures described in the literature for its correction. Traditionally, distal metatarsal osteotomies have been employed in the treatment of mild deformities, with proximal osteotomies being reserved for more severe presentations. The Scarf osteotomy without internal fixation allows large translations which can successfully correct severe hallux valgus deformities, without limitations related to screw placement.

Scarf截骨治疗躅外翻的短期疗效分析

背景：拇外翻为足踝外科常见病、多发病,目前以各种手术治疗为主,术后效果及复发率有较大差异。目的：探讨Scarf截骨联合其他手术方式治疗中、重度拇外翻的短期疗效。方法：2008年7月至2010年6月,采用Scarf截骨治疗中、重度坶外翻患者33例（41足）,男4例（4足）,女29例（37足）;年龄24-69岁,平均51．7岁。在Scarf截骨的基础上部分患者联合第一跖趾关节骨赘切除、软组织松解及拇趾近节趾骨Akin截骨等手术方式。采用美国足踝外科协会（American Orthopedic FootandAnkle Society,AOFAS）Maryland拇跖趾关节评分系统进行疗效评估。随访时摄足负重位X线片并测量拇外翻角（halluxvalgusangle,HVA）和第一、二跖骨间角（intermetatarsalangle．IMA）。结果：所有患者均获随访,时间12-36个月,平均20．4个月。HVA由术前32．78。矫正至10．18°,IMA由术前11．57。矫正至6．26。。Maryland拇跖趾关节评分：90-100分28足（68．3％）,80-89分11足（26．8％）,70-79分2足（4．9％）,优良率为95．1％（39／41）。结论：Scarf截骨术具有较好的自身稳定性,纠正畸形能力强,愈合快,坚固的内固定可使患者早期下地活动,并发症相对较少,联合其他手术方式是治疗中、重度拇外翻的理想方法。     

Early outcome of correction of hallux valgus with the Scarf osteotomy

INTRODUCTION: Aim of this study is to analyze complications as well as clinical and radiological results of the scarf osteotomy for the correction of hallux valgus. PATIENTS AND METHODS: Between 1994 and 1998 we performed a scarf osteotomy for the correction of hallux valgus in 45 cases. Indication was a symptomatic hallux valgus with an increased first intermetatarsal angle (IMA). Fixation of the osteotomy was performed with two 2.3 mm mini screws made of titaneum. Mobilisation was allowed with full weight bearing with a fore foot relief orthesis. Clinical results were valued with the fore foot scoring system (ffss). The determination of the IMA and hallux valgus angles (HVA) was performed with weight bearing d.p. radiographs. RESULTS: All osteotomies healed within the first 6 postoperative weeks. Removal of the screws was not necessary in any case. The preoperative ffss was 16.2 points. At the last follow up (16 month after surgery) the average value of the ffss was 59.1 points. Three patients reached a value below 35 points, two of them suffered from a rheumatic disease. Twenty patients assessed the cosmetic result as excellent, 16 as good, 4 as satisfactory and one as poor. The average IMA could be reduced significantly from 20.2 to 10.3 degrees. The HVA could be lowered from 37.5 to 20.9 degrees. In patients with an IMA of more than 20 degrees the HVA could be reduced to 23.1 degrees in contrast to 18.3 in patients with an IMA of less than 20 degrees. DISCUSSION: The scarf osteotomiy is a surgical procedure for the correction of hallux valgus due to increased IMA which is appropriate in patients younger than 50 years and older than 50 years. In cases of IMA more than 20 degrees correction of IMA and HVA was unsatisfactory.     

Scarf versus chevron osteotomy in hallux valgus: a randomized controlled trial in 96 patients

BACKGROUND: The degree of correction of hallux valgus deformity using a distal chevron osteotomy is reported as limited. The scarf osteotomy is reported to correct large intermetatarsal angles (IMA). The purpose of this study was to evaluate if one technique gave greater correction of the IMA and hallux valgus angle (HVA) than the other. METHODS: After informed consent, 96 feet in 83 patients were randomized into two treatment groups (49 scarf and 47 chevron osteotomies). The results were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) Hallux Valgus Scale and radiographic HVA and IMA measurements. RESULTS: At 27 (range 23-31) months followup both groups improved. The AOFAS score in the chevron group improved from 48 to 89 points and in the scarf group from 47 to 91 points. In the chevron group the HVA corrected from 30 to 17 degrees, and in the scarf group the HVA corrected from 29 to 18 degrees. In both groups, the IMA was corrected from 13 to 10 degrees. The differences were not statistically significant. Three patients in the chevron group developed a partial metatarsal head necrosis. In the scarf group, four patients developed grade 1 complex regional pain syndrome compared to one patient in the chevron group. CONCLUSIONS: No differences of statistical significance could be measured between the two groups with respect to the AOFAS score, HVA, and IMA. Although both groups showed good to excellent results, we favor the chevron osteotomy because the procedure is technically less demanding.     

The Scarf first metatarsal osteotomy in the correction of hallux valgus deformity

The correction of hallux valgus has been dramatically improved by the scarf 1^st metatarsal osteotomy, which brings great versatility for covering all the indications. Its strong fixation allows an early functional recovery; the long-term follow-up confirms the reliability of this procedure, which can be combined with other osteotomies and soft tissue procedures. However, the surgeon has to determine pre and intraoperatively the correction that has to be applied; this technique is not difficult but has to be performed accurately. This is the interest of this article, which emphasizes the technical features that have to be applied.

Scarf osteotomy for hallux valgus. A prospective clinical and pedobarographic study

We prospectively reviewed 24 patients (35 feet) who had been treated by a Scarf osteotomy and Akin closing-wedge osteotomy for hallux valgus between June 2000 and June 2002. There were three men and 21 women with a mean age of 46 years at the time of surgery. The mean follow-up time was 20 months. Our results showed that 50% of the patients were very satisfied, 42% were satisfied, and 8% were not satisfied. The mean American Orthopaedic Foot and Ankle Society score improved significantly from 52 points pre-operatively to 89 at follow-up (p < 0.001). The intermetatarsal and hallux valgus angles improved from the mean pre-operative values of 15 degrees and 33 degrees to 9 degrees and 14 degrees, respectively. These improvements were significant (p < 0.0001). The change in the distal metatarsal articular angle was not significant (p = 0.18). There was no significant change in the mean pedobarographic measurements of the first and second metatarsals after surgery (p = 0.2). The mean pedobarographic measurements of the first and second metatarsals at more than one year after surgery were within the normal range. Two patients had wound infections which settled after the administration of antibiotics. One patient had an intra-operative fracture of the first metatarsal and one required further surgery to remove a long distal screw which was irritating the medial sesamoids. We conclude that the Scarf osteotomy combined with the Akin closing-wedge osteotomy is safe and effective for the treatment of hallux valgus.
