Avascular necrosis of the first metatarsal head is uncommon. It is most often seen following a distal metatarsal osteotomy for hallux valgus. Although many cases may be subclinical, it is a powerful cause of failure of bunion surgery. Avascular necrosis of the first metatarsal head results in a series of events that begins with phases of avascularity; revascularization, with or without collapse; and reossification. Collapse may result in degenerative change of the metatarsophalangeal joint. We have recently experienced a case of avascular necrosis of the first metatarsal head.

Hallux valgus, or a 'bunion', is a deformity characterized by lateral deviation of the big toe. Surgery is indicated when conservative treatments have failed to result in improvement of symptoms. Operative techniques include simple bunionectomy, distal soft tissue procedure, phalangeal osteotomy, metatarsal osteotomy (distal, shaft, or proximal), arthrodesis (metatarsophalangeal or tarsometatarsal), or resection arthroplasty. Good results are expected when the selection of operative technique is based on the correct treatment principle.

There are many reports on the various methods of treatment for hallux valgus. 1st metatarsal proximal osteotomy with distal soft tissue procedure or 1st metatarsophalangeal joint arthrodesis has been conventionally used for treatment of severe hallux valgus. We performed a new double chevron osteotomy in 3 cases and obtained satisfying results. We present this procedure as a new method of treatment for severe hallux valgus.

Hallux valgus is a deformity characterized by lateral deviation of the great toe and medial deviation of the first metatarsal. When planning an operative treatment, it is important to realize that the deformity is tridimensional and diverse. Operative techniques include medial eminence resection, distal soft tissue procedure, first metatarsal osteotomy (distal, diaphyseal, proximal, or multiple), proximal phalanx osteotomy, arthrodesis (first metatarsophalangeal or metatarsocuneiform joint), and so on. Among these techniques, osteotomy is the main procedure for correcting the hallux valgus. The objective of this article is to describe the characteristics and recent advancements made for corrective osteotomies in the hallux valgus. The pathophysiology of the hallux valgus is also described.

Recurrence is a common complication following hallux valgus surgery. The postoperative recurrence rates have been reported to be between 2.7% and 16%. Reoperation is considered only for the recurrent deformities with intractable pain. The success of reoperation depends on identifying and addressing the cause of the recurrence appropriately. The surgical principle of reoperation for a recurrent hallux valgus is similar to that of the primary surgery, but arthrodesis and proximal metatarsal osteotomies with greater correcting power are adopted more frequently.

우리 인간의 신체는 약 206개의 뼈로 구성되어 있다. 그 중 양 발은 52개의 뼈, 38개의 근육, 214개의 인대로 형성되어 있는데, 얼마나 발이 인체에 있어서 중요한 지를 직접 느낄 수 있게 해주는 대목이다. 또한 발에는 모세혈관과 자율신경이 다른 어느 부위보다 집중적으로 분포되어 있어 발을‘제 2의 심장이다’라고 말하기도 한다. 발은 손 다음으로 많이 사용하는 부위이며 손에 비하여 육중한 무게를 지탱하는 구조로 인하여 많은 에너지를 필요로 한다. 그러므로 발끝까지 산소와 양분을 공급하는 혈관의 혈액이 원활하게 흐를 수 있게 하는 것은 건강에 있어 매우 중요한 요소이다 인체의 신비를 보여주는 우리 몸의 기관 그 두 번째, 발에 대해서 을지의대 을지병원 족부정형외과 이경태 교수, 인제대학교 서울백병원 족부클리닉 이우천 교수의 도움말로 알아본다.

More than 120 surgical methods for the correction of hallux valgus deformities have been reported. For the correction of moderate to severe hallux valgus deformities with aesthetic demands, minimally invasive surgery at the proximal area can be considered. This paper reports a case of moderate hallux valgus deformity treated by a minimally invasive proximal transverse metatarsal osteotomy followed by intramedullary plate fixation.

Hallux valgus with metatarsus adductus is difficult to treat and has a higher risk of recurrence after correction. Some treatments for hallux valgus with metatarsus adductus have been reported, but these are extensive procedures with a risk of complications associated with the shortening and malposition of the lesser metatarsals. The technique described here is easier to perform and has several advantages over the previously reported techniques.

Purpose: Authors analyzed and compared the treatment result of distal chevron osteotomy between with and without adductor tenotomy. Materials and Methods: 36 patients (60 feet) with a minimum follow-up of one year were involved in this retrospective study. The chevron osteotomy without adductor tenotomy was performed for 20 patients (30 feet) and chevron osteotomy with adductor tenotomy was done for 16 patients (30 feet). The first metatarsophalangeal (MTP) angle and angle between first and second metatarsal longitudinal axis (IM) was measured. The difference of these angles were measured pre-and postoperatively and compared using Student's T-test. Results: In the group of chevron osteotomy with adductor tenotomy, the mean first MTP angle corrected $29^{\circ}$ pre-operatively to $9^{\circ}$ and the mean first IM angle corrected $16^{\circ}$ pre-operatively to $12^{\circ}$. In the group of chevron osteotomy without adductor tenotomy the mean first MTP angle corrected $31^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05) and the mean first IM angle corrected $13^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05). Deep peroneal neuroma were found in 3 cases of chevron osteotomy with adductor tenotomy. Conclusions: Adductor tenotomy should be performed in selected patient with chevron osteotomy to prevent deep peroneal neuroma.

Purpose: To investigate the relationship between radiographic parameters of the forefoot and plantar pressure in patients with hallux valgus. Materials and Methods: Plantar pressures of 21 patients with hallux valgus were examined with EMED-ST system. The data were compared with the parameters on the simple weightbearing dorsoplantar radiographs of the feet. The radiographic parameters that were measured were hallux valgus angle, 1-2 intermetatarsal angle, relative lengths of the metatarsals which were measured with the methods described by Maestro et al. and Okuda et al. Results: Statistically significant correlation was found between peak pressures under 2, 3 metatarsal heads and the relative lengths of 2, 3 metatarsals which were measured with the method described by Maestro et al. However they could explain only 13% of the pressures under the 2, 3 metatarsal heads by multivariate analysis. Conclusion: These results suggest that we cannot predict the plantar pressures under the foot with the parameters on the simple weightbearing dorsoplantar radiographs of the feet.
