RESUMO
BACKGROUND: Hypermobility of the first metatarsocuneiform (MC) joint is one of the causes believed to contribute to symptomatic hallux valgus. An arthrodesis of the first MC joint offers definitive correction of the intermetatarsal angle. This procedure can be associated with pseudoarthrosis and shortening of the first ray. This study presents our experience and results with an arthroscopic technique for performing this arthrodesis. MATERIALS AND METHODS: Five patients with severe hallux valgus associated with hypermobility of the first MC joint were treated with this operation. RESULTS: The functional assessment scales revealed very good results. Radiographic evaluation confirmed fusion in all the patients. The hallux valgus angle improved by 25.6°, the intermetatarsal angle improved by 10.6°. The shortening of the first ray was limited to 2.7 mm. CONCLUSION: This new technique is a valid option for performing an arthrodesis of the MC joint.

The results of operative treatment of 45 flexible flat feet (29 patients) using the sinus tarsi spacer are reported. Although radiological improvement in both the talar declination and the ground-navicular distance was found, our patients suffered from pain and functional impairment for an average period of 5 months. An unacceptably high rate of spacer dislocation was noted. Furthermore, the literature indicates spontaneous improvement as the natural history of flexible flat feet. We therefore no longer advise the sinus tarsi spacer as a routine treatment for flexible flat feet.
