Effectiveness of Lateral Soft Tissue Release of the 1st Metatarsophalangeal Joint Through a Medial Transarticular Approach – A Cadaver Study:

摘要

Category:BunionIntroduction/Purpose:First metatarsophalangeal joint lateral soft tissue release is frequently performed during corrective surgery for hallux valgus deformity. Surgical approaches include an open dorsal approach as well as a medial transarticular approach. The medial transarticular approach avoids the need for a second incision while also attenuating the risk of avascular necrosis of the first metatarsal head. However, this method is limited by the poor visualization of the lateral structures through the joint. The objective of this study was to evaluate the effectiveness of the medial transarticular approach for lateral soft tissue release in the 1st metatarsophalangeal joint.Methods:Ten below-the-knee fresh-frozen cadaveric specimens were used (6 females, 4 males). The mean age was 73.4 years. Two specimens had moderate hallux valgus deformity. None of the samples had considerable degenerative changes of the first metatarsophalangeal joint. Lateral soft tissue release was performed using ...
