Purpose: To evaluate and analyze the incidence, clinical features, cause and surgical outcomes of iatrogenic hallux varus deformity after hallux valgus surgery. Materials and Methods: Twenty-six Hallux varus deformities after hallux valgus surgery were evaluated. Clinical tolerability, patient's satisfaction and the main causative factor for varus deformity were evaluated. Radiologically, we measured the 1st intermetatarsal angle and hallux valgus angle on pre- & postoperatively. Results: 10 cases of 26 varus deformities were clinically intolerable. The patients complaint of mainly cosmetic and shoe fitting problems rather than pain and the main cause of deformities were over-correction of 1 st intermetatarsal angle. Radiologically, the average 1st intermetatarsal angle was 2.4 degrees and the hallux valgus angle was -9.2 degrees. After varus correction surgery, the average follow up were 17 months and the average 1st intermetatarsal angle was 2.3 degrees and the hallux valgus angle was 2.7 degrees. The average score of AOFAS Hallux Metatarsophalangeal -Interphalangeal Scale was 91 points. Conclusion: The hallux varus deformity after hallux valgus surgery came from mainly overcorrection of 1 st intermetatarsal angle. The management composed of just observation, tendon transfer and fusion, and each method could get satifactory results with appropriate indication.

Purpose: This study was performed to investigate the radiological characteristics of the degenerative arthritis of the ankle using the standing radiographs. Materials and Methods: From June 2001 to May 2005, 36 patients (56 ankles) who were treated for osteoarthritis of ankle were analysed. Angle of tibial shaft and tibial joint surface on AP view (TSA), angle of tibial joint surface on lateral view (TLS), tibial and medial malleolus angle (TMM) and talo-1st metatarsal angle were checked on standing radiograph. The patients with medial joint and total joint involvement were categorized into three stages according to the location of involvement. The degree of joint space narrowing was categorized into two groups. Results: There were no significant differences in TSA, TLS, TMM and talo-1st metatarsal angle with regard to the stage of arthritis. However, the difference between the less severe group and the severe group existed. Conclusion: Angular deformity was not correlated with stage, but correlated with severity. The deformity of distal tibial articular surface does not seem to be a cause of primary osteoartiritis, but rather a result from it.

Purpose: To evaluate the results and effectiveness of distal chevron osteotomy combined with lateral soft tissue release for the correction of hallux valgus deformity. Materials and Methods: 31 patients who underwent distal chevron osteotomy with lateral soft tissue release between July 2002 and June 2003, were analyzed in terms of hallux valgus angle, intermetatarsal angle, subluxation of sesamoid, AOFAS score and the occurrence of avascular necrosis of the first metatarsal head. Results: The mean amount of the correction of hallux valgus angle was $26.3^{\circ}$. The mean amount of the correction of intermetatarsal angle was $6.6^{\circ}$. The mean amount of the correction of sesamoid subluxation was 1.2 points. The mean improvement of AOFAS score was 25.8 points. Avascular necrosis of the first metatarsal head was not found in any cases. Conclusion: For correction of hallux valgus deformity, distal chevron osteotomy with lateral soft tissue release showed improvement of hallux valgus angle, sesamoid subluxation and AOFAS score with no evidence of avascular necrosis of the first metatarsal head.

Eleven patients with calcaneal fracture had 2 acute compartment syndrome of the feet and 9 late complication of the compartment syndrome of the feet. An interstitial pressure of more than 30 mmHg in either the central or interosseous compartment was considered pathologic and was treated by fasciotomy performed medially. Rigid claw toe deformity was treated by excision of the head and neck of the proximal phalanx, dorsal capsular release of the metatarsophalangeal joint, and lengthening of the extensor tendon. Patients were evaluated at a mean of 35 months(range, 21 - 44 months) after operation, and the examination was directed specifically toward symptoms and signs of myoneural ischemia, and walking pain. At follow-up, 2 patients with acute compartment syndrome of the foot had no evidence of myoneural ischemia, 9 patients with claw toe deformity had no pain with walking. Based on our clinical observations, we concluded that compartment syndrome of the foot may occur after the calcaneal fracture and fasciotomy is effective treatment for the prevention of the long term sequelae of this debilitating condition.

The bunionette, or a 'tailor's bunion', is a lateral bony prominence of the fifth metatarsal head. A bony deformity itself rarely causes symptom but if a painful inflammation of the overlying soft tissue is accompanied, it needs treatment. Conservative care using a shoe modification, padding, or orthosis is effective in most cases. Surgical management is indicated when the conservative methods have failed to improve symptoms, and the techniques include exostectomy, metatarsal osteotomies (distal, diaphyseal, or proximal), metatarsal head resection or fifth ray resection. We reviewed the etiology, clinical features, radiographic classification, nonoperative and operative treatments of the bunionette.

Flatfoot is defined as loss of medial arch with hindfoot valgus, but normal condition is obscure due to wide individual variance. Loss or decreasing of medial longitudinal arch with radiographic image is clinically diagnosed as flatfoot. Flatfoot without symptoms is not an indication for treatment. The etiologies of flatfoot are congenital cause, hypermobility, tarsal coalition, neuromuscular disease, post-traumatic deformity, Charcot arthropathy, and posterior tibial tendon dysfuction. The flatfoot is classified as congenital and acquired, flexible, and rigid. The diagnosis is made by physical examination and radiographic findings. In particular, the posterior tibial tendon dysfunction is known as adult acquired flatfoot.

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.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.

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.
