Abstract
Purpose: Evaluate the effectiveness of medial transarticular approach for lateral soft tissue release in the 1st metatarsophalangeal joint.
Methods: Ten fresh-frozen cadavers. Lateral soft tissue release was performed using a single 2.5 cm medial incision. Targeted structures were: lateral collateral ligament, lateral capsule, adductor hallucis muscle tendon and lateral metatarsosesamoid suspensory ligament. Extended lateral dissection of the 1st intermetatarsal space was performed to evaluate the technique's accuracy. Percentage of successful release of each targeted structure (4 total) and injuries to non-targeted structures were registered.
Results: All four targeted structures were successfully released (100% success rate) in seven of the ten cadavers. Three out of four targeted structures were successfully released (75%) in one cadaver, while two of the four and one of the four targeted structures were successfully released in the other two cadavers (50% and 25%, respectively). The lateral collateral ligament was successfully released in all cadavers. The lateral joint capsule, adductor hallucis muscle tendon, and lateral metatarsosesamoid suspensory ligament were released in 80% of the specimens. Chondral damage of the 1st metatarsal head and unintended release of the lateral head of the flexor hallucis brevis occurred respectively in 40% and 50% of the procedures. No injuries to FHL tendon, neurovascular bundle, deep transverse metatarsal ligament were recorded.
Conclusion: Lateral soft tissue release of the first metatarsophalangeal joint can be successfully performed through a medial transarticular approach. Inadvertent release of the flexor hallux brevis lateral head and chondral damage of the 1st metatarsal head are complications to be considered.
