We experienced a rare case of parosteal lipoma, which located on the periosteum of the foot 4th metatarsus. A 22-year-old woman visited the hospital with painful mass in her foot. Based on the assessment of plain radiographs, computed tomography scan, and magnetic resonance image, it was suspected as lipoma. Marginal excision was performed and parosteal lipoma was confirmed histologically. Any local recurrence and complications were not observed in 2 years after surgery.

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: The aim of this study was to investigate the radiological characteristics of the osteoarthritis of the second metatarsophalangeal (MTP) and tarsometatarsal (TMT) joint. MATERIALS AND METHODS: Between January 2002 and August 2010, 27 patients (33 feet) who had second metatarsal osteoarthritis (OA) were reviewed retrospectively. Group 1 was 14 patients (17 feet) with second MTP joint OA. Group 2 was 13 patients (16 feet) with second TMT joint OA. Group 3 was 24 patients (25 feet) had hallux valgus without second metatarsal (MT) OA as control. Weight bearing foot anteroposterior (AP) and lateral view were checked, and measured hallux valgus angle, metatarsus adductus angle (MAA), second MT functional length, first and second MT length by Hardy & Clapham method on AP view, angle of second MT with horizontal plane, calcaneal pitch, talo-first MT on lateral view. RESULTS: On weight bearing foot AP view, second MT functional length of group 1, 2, 3 was 2.4 mm, -0.1 mm, 0.7 mm and MAA of group 1, 2, 3 was 17.7degrees, 17.7degrees, 14.5degrees. Second MT functional length of group 1 was longer than control group and it was statistically significant. MAA was significant different between group 1-3 and group 2-3. Angle of second MT with horizontal plane of group 2 was smaller than control group and it was statistically significant. Other radiographic parameters have no statistical significance. CONCLUSION: Group 1 has long functional length of second MT and group 2 has small angle of second MT with horizontal plane.

PURPOSE: The purpose of this study is to evaluate the characteristics of hallux valgus with severe hallux valgus angle (HVA) and moderate intermetatarsal angle (IMA) after proximal chevron osteotomy. MATERIALS AND METHODS: Between January 2008 and December 2010, 41 patients (48 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic severe hallux valgus deformity (HVA > or =40degrees). Patients were divided into two groups, group M (IMA <18degrees) and group S (IMA > or =18degrees). Mean age of patients was 55.7 years (34~70 years) in group M and 60.0 years (44~78 years) in group S. Mean duration of follow-up was 20.4 months (12~41 months) in group M and 18.5 months (12~35 months) in group S. Radiographic parameters, including HVA, IMA, sesamoid position, metatarsus adductus angle (MAA), and distal metatarsal articular angle (DMAA), were compared between groups. Clinical results were assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS). Recurrence rate at the last follow-up was compared between group M and group S. RESULTS: Preoperative HVA and grade of sesamoid position did not differ between the groups. However, immediate postoperative HVA and grade of sesamoid position were significantly larger in group M. Preoperative MAA and DMAA were significantly larger in group M. No significant difference in AOFAS score and VAS was observed between the groups at the last follow-up. Ten of the 27 feet (37.0%) in group M and two of the 21 feet (9.5%) in group S showed hallux valgus recurrence at the last follow-up. Group M showed a significantly higher recurrence rate than group S. CONCLUSION: Recurrence rate for severe hallux valgus with moderate IMA is higher than that of severe hallux valgus with severe IMA.

PURPOSE: The purpose of this study was to evaluate retrospectively the clinical results of closed reduction and percutaneous screw fixation for unstable injuries on stress radiographs in subtle injuries of Lisfranc joint. MATERIALS AND METHODS: From June 1997 to March 2003, 6 cases of unstable injuries on stress radiograph in subtle injuries of Lisfranc joint were treated by percutaneous cannulated screw fixation after closed reduction. All cases were injuried by indirect force (twisting injury). The average diastasis between the 1st and 2nd metatarsal base was 3 mm (2-4 mm) on initial nonweight bearing AP radiograph. The average follow-up period was 20 months. Clinical evaluation was assessed according to the American Orthopedic Foot and Ankle Society (AOFAS) midfoot score. RESULTS: The AOFAS midfoot score was average 86 (80-90) points. The average diastasis between 1st and 2nd metatarsal base was 2 mm (1-3 mm) on weight bearing AP radiograph in final follow up. The final diastasis was increased slightly than diastasis in initial postoperative radiographs. But the clinical results were good. There was no correlation between the degree of diastasis and the clinical results. On weight bearing lateral radiograph, the average difference with normal foot in the distance between plantar aspect of 5th metatarsus and medial cuneiform was 2 mm (0-3 mm). One case had mild arthritic change on the radiographs CONCLUSION: When the Lisfranc injuries, especially in the subtle injuries were suspicious, the stress views are helpful to assess stability of the Lisfranc injuries and planning of treatment. For unstable injuries on stress radiographs in subtle injuries of Lisfranc joint, closed reduction and percutaneous screw fixation is useful method to expect good clinical results.

Residual adduction of the forefoot is recognized as common sequelae of treated clubfoot. The causes of residual forefoot adduction may be metatarsus varus, talonavicular subluxation and subluxation of the calcaneocuboid joint. But, less attention has been given to subluxation of the calcaneocuboid joint. The purpose of this study was to assess the correlation between subluxation of calcaneocuboid joint and residual forefoot adduction, and to suggest the guideline of treatment for subluxation of the calcaneocuboid joint. A retrospective analysis was done by the medical records and radiographs of 48 clubfeet (thirty-four patients) that had been treated with an operation (thirty-three feet) or conservative methods (fifteen feet) at the Kang-Nam St. Mary's Hospital, between 1990 and 1995. The severity of adduction of the forefoot was determined by the angle of talo-first metatarsal. Subluxation of the calcaneocuboid joint was measured by using a grading system. And then, the forefoot adduction was categorized to mild, moderate, and severe degree according to the talo-first metatarsal angle. The average length of follow-up was eighteen months. Of the 48 feet, seventeen had no subluxation of the calcaneocuboid joint (35.4%), twenty-seven Grade I subluxation (56.3%), and four Grade 3 subluxation (8.3%) on initial radiograph. On the final radiograph, twenty-five feet had a residual adduction of the forefoot. In reviewing the distribution of the residual forefoot adduction according to the initial grade of the calcaneocuboid joint subluxation, Grade 0 subluxation had 6 forefoot adduction (35.3%), Grade I subluxation had 15 forefoot adduction (55.6%), and Grade 3 subluxation had 4 forefoot adduction (100%). Grade II calcaneocuboid joint subluxation had two severe residual forefoot adduction deformities (2 out of 4 cases) and Grade I calcaneocuboid joint subluxation had one severe residual forefoot adduction deformity (1 out of 15 cases). But, there was no severe forefoot adduction deformity in Grade 0 calcaneocuboid joint subluxation. The average angle of talo-first metatarsal was decreased in Grade 0 and Grade I subluxation, whereas it was increased in Grade II subluxation. Conclusively, we believe that there is significant correlation between the severity of subluxation of calcaneocuboid joint and residual forefoot adduction, and that the patients who have a Grade II subluxation of calcaneocuboid joint need operative correction of the subluxation of the calcaneocuboid joint.

A case of fixed matatarsus Varus developed in right foot in 10 years old girl is reported, which was reduced surgically. Roentgenologically the navicular bone was showed to be displaced laterally from the head of talus and all metatarsals were angulated medially. Though most deformies should be corrected by the use of corrective cast, this deformity was treated surgically without initial conservative method. After surgery and cast immobilization the foot was corrected and function is good.
