The Effect of Temporary K-wire Fixation in the Plate Fixation for Displaced Intra-articular Calcaneal Fracture / 대한족부족관절학회지

PURPOSE: This study was designed to evaluate the clinical efficacy of temporary K-wire fixation in F-plate fixation for displaced intraarticular calcaneal fractures. MATERIALS AND METHODS: Two groups (group 1 with F-plate fixation only and group 2 with temporary K-wire fixation and F-plate fixation) of patients were included in this study. The temporary K-wire was removed six weeks after the operation. Each group consisted of 33 cases. Rotational axis angles were measured radiographically and the foot and ankle outcome score (FAOS) was used for clinical assessment. RESULTS: In group 1, the mean rotational axis angle was reduced from 27degrees preoperatively to 5.59degrees postoperatively and the angle at last follow-up was 9.94degrees. There was an increase in angle of 4.35degrees between postoperative and the last follow-up measurement. In group 2, the mean rotational axis angle was reduced from 21.2degrees preoperatively to 4.39degrees postoperatively and the angle at last follow-up was 5.91degrees. There was an increase in angle of 1.52degrees between postoperative and the last follow-up measurement. Significant difference in the changes of rotational axis angle was observed between the two groups. However, no significant difference in FAOS was observed between the two groups. CONCLUSION: Temporary K-wire fixation can prevent reduction loss when treating displaced intra-articular calcaneal fractures with an F-plate.

Freiberg's Disease and Metatarsophalangeal Joint Instability / 대한족부족관절학회지

Freiberg's disease is a osteochondrosis of a metatarsal head that is recognized as primarily a disorder of the second metatarsal. It is seen more often in girls. Pain and limitation of motion of the affected joint is the predominant clincal feature. The radiographic appearance demonstrates from osteosclerosis in the early stage to osteolysis with collapse in the later stage. Conservative therapy may take the form of rest, a stiff shoe, and even a cast support to decrease the stress across the joint. Surgical intervention may also be of benefit. Surgery have been attempted either to modify the diseae process or to salvage the situation once the metatarsophalangeal joint develops degenerative changes. Metatarsophalangeal joint instability is common cause of forefoot pain that can develop in association with a traumatic episode and inflamatory tissue disorders as well as neighboring toe deformities. The second ray is by far the most frequently involved. The diagnosis can be made by clinical observation and physical examination including drawer test. Many surgical procedures have beem recommended when conservative treatment has failed. Procedures described range from soft tissue releases and tendon trasfer to the direct plantar plate repair combined with a Weil osteotomy.
