Background: Patients with severe hallux valgus deformity present technical and operative challenges with high rates of recurrence and residual deformity. The clinical and radiologic outcomes of percutaneous surgery for severe hallux valgus are not known. Methods: A retrospective review of consecutive patients with a hallux valgus angle (HVA) >40 degrees or intermetatarsal angle (IMA) >20 degrees who underwent third-generation percutaneous chevron and Akin osteotomy (PECA) for hallux valgus deformity correction. Results: Between December 2012 and August 2019, 59 feet in 50 patients underwent PECA. Preoperative and follow-up radiographic data were available for 53 feet (89.8%). Postoperative clinical patient-reported outcome measures and satisfaction results were available for 51 feet (86.4%). The mean clinical and radiographic follow-up was 3.1 years and the mean postoperative Manchester-Oxford Foot Questionnaire Index score was 15.1. There was a statistically significant improvement ( P < .001) in both IMA and HVA following surgery (IMA 17.5-5.1 degrees; HVA 44.1-11.5 degrees). All patients reported they were satisfied with their outcome, with 76.8% reporting they were highly satisfied. The hallux valgus recurrence rate was 7.5%. Conclusion: Percutaneous surgery for severe hallux valgus deformity can achieve a large deformity correction, patient satisfaction, and quality of life, with reasonable rates of residual deformity and low rates of recurrence.

Category: Bunion Introduction/Purpose: Hallux valgus deformity is recently a common disease involved in the foot and ankle and many procedures are recommended globally. However it is controversial about the operative treatment for severe hallux valgus. Many authors have reported the technical difficulties and various complications. We performed rotated insertion metatarsal osteotomy with the distal soft tissue procedure for severe hallux valgus deformity since January 2008. The purpose of this study is to evaluate the medium-term outcome of this procedure. Methods: Two hundred thirty-two feet in 173 patients were enrolled in this study and followed them up for a mean of 44.5 months. The mean age at the operation was 64.5 years. Hallux valgus angle(HVA) and intermetatarsal angle(IMA) were measured. This procedure consists of the rotated insertion metatarsal osteotomy and the distal soft tissue procedure. This diaphysial longitudinal metatarsal oblique osteotomy was performed from proximally- medial site of the first metatarsal directed to distally- lateral site through the dorsal exposure. The tip of osteotomized proximal metatarsal was formed at the dorso-distal site to insert in the central intramedullary aspect of osteotomized distal metatarsal. The second triangular cut of one third of dorso-plantar thick was made about 10 to 15 mm length from the lateral tip of osteomized proximal metatarsal. The internal fixation was performed with locking plate with screws. As a result, osteotomized sites were locked each other such as a puzzle. Results: The mean preoperative HVA and IMA were 43.8 degrees and 20.1 degrees. The mean postoperative HVA and IMA were decreased to 9.0 degrees and 6.1 degrees. AOFAS scores improved from 49.3 to 89.7. All cases were obtained complete union. Postoperative displacement was in 12 feet (5.2%) and followed under-correction (or recurrence). Overcorrection (hallux varus) occurred in 10 feet (4.7%). Wound healing was delayed in 21 feet (9.1%). In general, we found no severe complication and unsatisfactory result. Conclusion: This procedure provided satisfactory result for severe hallux valgus deformity. Especially the rigid fixation at the site of metatarsal osteotomy was much stronger because of the insertion and locking plate. However the further more outcomes in detail are essential for longer term follow-up.

First Time

It has been believed that the correction of metatarsus primus varus (MPV) deformity of hallux valgus foot using nonosteotomy procedures would be compromised by the presence of os intermetatarseum (OI). Therefore, no soft tissue procedure has ever been reported for the correction of MPV deformity of hallux valgus foot. This is a case report of a female patient with bilateral hallux valgus deformity and also a large OI of her left foot that was corrected, satisfactorily and simultaneously, with a soft tissue technique called syndesmosis procedure, without osteotomy or OI resection. Excellent feet function was observed for 2 years until her last follow-up examination without any symptoms or signs of problems relating to the OI in her left foot. This case report demonstrated for the first time that OI may not interfere with proper MPV deformity correction because it can be preexisting and X-ray can be misleading.

Purpose: We report 3- to 8-year follow-up results for the first tarsometatarsal joint derotational arthrodesis. Methods: A total of 70 patients (88 feet) with symptomatic flexible hallux valgus were operated between 2003 and 2009. In all, 66 patients (94.3%) with 84 (95.5%) feet were enrolled in retrospective analysis; of those, 58 (87.9%) patients with 76 (90.5%) feet were followed for a mean of 5.1 (range: 3.0–8.3) years. Preoperative, 6 week postoperative, and late follow-up weightbearing radiographs were evaluated along with clinical examination and questionnaires. Results: The mean hallux valgus angle improved 13.4° (95% confidence interval: 11.6–15.1, p < .001) at the latest follow-up, while the mean intermetatarsal angle correction was 4.5° (95% confidence interval: 3.7–5.2, p < .001). There were three (4.0%) nonunions, and seven (9.2%) feet needed reoperation during follow-up. Conclusion: First tarsometatarsal joint derotational arthrodesis is an effective procedure for correcting flexible hallux valgus deformity and provides a satisfactory long-term outcome.

Background: Scarf midshaft metatarsal osteotomy has become increasingly popular as a treatment option for moderate-to-severe hallux valgus deformities because of its great versatility. Numerous studies on Scarf osteotomy have been published. However, no prospective studies were available until 2002. Since then, only short-term follow-up prospective studies have been published. We present the results of a prospective study of 21 patients treated by Scarf osteotomy for hallux valgus with follow-up of 8 years. Methods: Between August 1, 1999, and October 31, 1999, 23 patients (23 feet) with moderate-to-severe hallux valgus deformity were included. Clinical (American Orthopaedic Foot and Ankle Society score) and radiologic (hallux valgus angle, first intermetatarsal angle, and sesamoid position) evaluations were performed preoperatively and 1 and 8 years postoperatively. Results: Clinical evaluation showed a significant improvement in the mean forefoot score from 47 to 83 (of a possible 100) at 1 year (P &lt; .001). Radiographic evaluation showed significant improvement in the hallux valgus angle (mean improvement, 19°; P &lt; .001) and in the intermetatarsal angle (mean improvement, 6°; P &lt; .001). These clinical and radiographic results were maintained at the final evaluation 8 years postoperatively. Conclusions: Scarf osteotomy tends to provide predictable and sustainable correction of moderate-to-severe hallux valgus deformities. (J Am Podiatr Med Assoc 100(1): 35–40, 2010)

Background: The purpose of this study was to determine the results of an arthrodesis technique of the first metatarsophalangeal joint (MTPJ) using a precontoured dorsal plate to correct the hallux valgus deformity. Methods: This was a retrospective analysis of outcomes for first MTPJ arthrodesis performed using 2 precontoured dorsal plates. Radiographic outcomes (intermetatarsal angle [IMA] and hallux valgus angle [HVA]) and patient-reported functional outcome measures (Short-Form 12 and Foot and Ankle Outcome Score) were recorded and compared. Results: Fifty-five patients underwent 77 first MTPJ arthrodeses for severe hallux valgus deformity with associated degenerative changes at the first MTPJ. The mean reduction of the IMA was 5.67° ( P < .05) and the mean reduction of the HVA was 33° ( P < .05). The Short-Form 12 assessment of global health demonstrated a significant improvement in both the physical and mental health composite scores by 16.4 points and 10.4 points ( P < .05), respectively. The Foot and Ankle Outcome Score demonstrated a cumulative decrease of 35% (59.28; P < .05) in all domains. Conclusions: First MTPJ arthrodesis using a precontoured dorsal plate is a successful procedure with a high union rate, low complication rate, and a high level of patient-reported satisfaction. Levels of Evidence: Level III.

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Distal 1st metatarsal chevron osteotomy is one of the most frequently performed procedures for treatment of mild to moderate hallux valgus, though the optimal method of fixation remains in question. The use of Kirschner wires (K-wires) is an established technique of temporary internal fixation that offers a simple and cost-effective strategy. Previous studies have reported removal of K-wires ranging from 4-8 weeks following a chevron osteotomy, though even earlier removal may be acceptable and serve to decrease the risk of complications. The purpose of this study was to determine if early removal of K-wires is adequate to maintain correction of a hallux valgus deformity following distal 1st metatarsal chevron osteotomy. Methods: We conducted a retrospective review of patients who had their 1st metatarsal K-wire removed at their first (2week) postoperative visit after undergoing primary chevron osteotomy for treatment of a hallux valgus deformity with a single foot and ankle fellowship-trained orthopaedic surgeon from 2010-2018. Exclusion criteria consisted of revision osteotomies, K-wire removal >=21 days postoperatively, concomitant midfoot or hindfoot procedures, and lack of preoperative or at least 3-month postoperative radiographs. Preoperative, 6-week, 3-month, and longer-term intermetatarsal angles (IMA) were measured on weightbearing anteroposterior (AP) radiographs by an individual blinded to and not involved in the care of the patients. The pre- and postoperative tibial sesamoid position according to the Hardy and Clapham classification (grades 1-7) was also recorded on those with longer-term AP radiographs on file. From 2010-2018, 275 patients underwent 295 primary chevron osteotomies by the senior author, with 72 osteotomies (24.4%) excluded, leaving 223 (75.6%) available for analysis. Results: Patients had a mean preoperative IMA of 11.4 +- 2.0 degrees. At 6 weeks, 3 months, and longer-term follow-up averaging 24.6 months, patients had mean IMA of 3.8 +- 1.7, 4.6 +- 1.7, and 4.6 +- 2.2 degrees, respectively, all of which were significantly less (P<0.0001) than the mean preoperative IMA. Of those with longer-term follow-up (n=56, 25.1%), the tibial sesamoid position decreased from 4.6 +- 0.8 preoperatively to 2.3 +- 0.7 at 6 weeks, 2.4 +- 0.8 at 3 months, and 2.6 +- 0.9 at final follow-up. All 3 postoperative time points of tibial sesamoid positions were significantly less (P<0.0001) than the mean preoperative position. Conclusion: Our findings demonstrate that removal of K-wires less than 3 weeks following a distal 1st metatarsal chevron osteotomy is sufficient to maintain correction of hallux valgus deformity. The loss of correction in this study is in line with previous studies, where K-wires were removed at later postoperative time points. Delayed wire removal has been shown to lead to increased complications, such as pin tract infection and bending or breakage of the K-wire, which can require not only additional office visits but also potential revision procedures. Removing the K-wire in the early postoperative period should be considered effective and safe.

Category: Bunion Introduction/Purpose: The scarf osteotomy has gained in popularity for the treatment of a symptomatic hallux valgus deformity due to its inherent stability, versatility of correction and early mobilization. We have reported parallel-shaped modified scarf osteotomy(PSMSO) with good functional outcomes and no complication as stress fracture or troughing. However, we encountered second transfer metatarsalgia after the osteotomy. The scarf osteotomy can be shortened, but there was no specific amount of shortening that will produce transfer metatarsalgia in limitation of our literature review. In this study, we measured the shortening of first metatarsal length and investigated the relation of first metatarsal length and second transfer metatarsalgia after PSMSO for hallux valgus deformity. Methods: We retrospectively reviewed 168 consecutive PSMSOs performed in 124 patients with hallux valgus deformity between March 2009 and August 2015. Concomitant other pathologies of foot or previous second metatarsalgia were excluded. After excluding 45 cases, 123 cases in 88 patients were included. For clinical assessment, VAS, the AOFAS Hallux Metatarsophalangeal-Interphalangeal (AOFAS Hallux MTP-IP) Scale were obtained. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMAA), the first metatarsal length measured by a modified Davies and Saxby’s method and the protrusion of second metatarsal relative to first metatarsal using the Maestro’s method were assessed on standard weight bearing radiographs of the foot. For evaluation of the development of second transfer metatarsalgia, callosity or tenderness beneath the second metatarsal head was investigated. After identifying the lesion, we divided two groups with and without second transfer metatarsalgia and compared the variables after propensity score matching. Results: Mean follow-up period was 20.6±7.8 (12-66) months. The mean VAS and AOFAS Hallux MTP-IP score improved significantly (p<0.001). Significant corrections in the HVA, IMA and DMAA were obtained and the mean shortening of the first metatarsal length and the mean relative lengthening of second metatarsal protrusion were -3.1±2.5 mm and +2.5±2.8 mm at last follow-up (p<0.001, p<0.001). Eleven (8.9%, 11/123) cases developed second transfer metatarsalgia after PSMSO. After propensity score matching considered baseline characteristics, 9 cases with second transfer metatarsalgia were compared to 31 cases without it. The group with transfer metatarsalgia showed significant shortening in first metatarsal length and lengthening of second metatarsal protrusion relative to first metatarsal compared to those without the transfer lesion (-4.8±3.8 vs -2.0±2.1, p=0.013, +4.2±1.6 vs +1.9±2.1, p=0.005). Conclusion: Transfer metatarsalgia is one of numerous possible complications after scarf osteotomy. To avoid complications, we suggest that shortening of first metatarsal bone length should be minimized within -2 mm and second metatarsal protrusion relative to first metatarsal kept within +1.9 mm with considering the metatarsal parabola. If the shortening of first metatarsal was done over -4.8 mm, the additional procedure for second metatarsal may be considered.

Background First metatarsophalangeal joint fusion is a commonly used procedure for treating many pathologic disorders of the first ray. Historically, hallux valgus deformity with severely increased intermetatarsal angle or metatarsus primus adductus indicated need for a proximal metatarsal procedure. However, the effectiveness and reliability of first metatarsophalangeal joint arthrodesis in reducing the intermetatarsal angle has been increasingly described in the literature. We compared findings at our institution with current literature for further validation of this well-accepted procedure in correcting hallux valgus deformity with high intermetatarsal angle. Methods Weightbearing preoperative and postoperative radiographs of 43 patients, 31 women and 12 men, meeting the inclusion and exclusion criteria were identified. Two independent investigators measured the hallux abductus and intermetatarsal angles. Preoperative and postoperative measurements for each angle were compared and average reduction calculated. The data were further analyzed by grouping deformities as mild, moderate, and severe. Mean follow-up was 10 months. Results The overall mean preoperative intermetatarsal and hallux abductus angles decreased significantly (from 13.09° to 9.33° and from 23.72° to 12.19°, respectively; both P &lt; .01). When grouping deformities as mild, moderate, and severe, all of the categories maintained reduction of intermetatarsal and hallux abductus angles (P &lt; .01). Furthermore, the mean reduction of the intermetatarsal and hallux abductus angles seemed to correlate with preoperative deformity severity. Conclusions In patients undergoing correction of hallux valgus deformity, first metatarsophalangeal joint arthrodesis produced consistent reductions in the intermetatarsal and hallux abductus angles. Furthermore, these findings are consistent with those reported by other institutions.
