The distal Chevron or Austin procedure, is arguably the most prominent of the distal metatarsal osteotomies. Recent studies in the literature have shown a trend in recommending this osteotomy or one if it’s modifications for even severe hallux valgus deformities. Therefore we aimed to compare the clinical and pedobarographic results after chevron osteotomy in patients with moderate hallux valgus deformity. We investigated a homogeneous lot of 10 patients undergoing hallux valgus correction using distal chevron technique. In order to quantify the improvement of the gait in these patients, several biomechanical parameters have been measured using a matrix of pressure sensors that provide us the vertical reaction forces when the foot is in physical contact with it. Results show an improvement in patient’s velocity and cadence after the surgery, and also a smaller variability in gait. Nevertheless, optimal clinical outcomes are still found to have altered ground reaction forces on pedobarographic assessment.

Coalition of the hallux sesamoids is an extremely rare condition. To our knowledge, only 1 case report has been published. We report a case of severe hallux valgus deformities with coalitions of the hallux sesamoids. The coalitions themselves were asymptomatic; however, this severe hallux valgus deformity needed to be surgically treated. The hallux sesamoids in both feet appeared to be fused and heart shaped on anteroposterior radiographs and dumbbell shaped on axial radiographs. It is known that postoperative incomplete reduction of the medial sesamoids can be a risk factor for the recurrence of hallux valgus. The computed tomography scan demonstrated a groove in the bottom of the center of the heart-shaped sesamoid. The flexor hallucis longus tendon was located in the groove. Therefore, a modified Lapidus procedure was performed considering the medial half of the heart-shaped sesamoid as the medial sesamoid. Although delayed union occurred, successful correction of the deformity was achieved. Levels of Evidence: Level IV

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.
