Iatrogenic hallux varus surgical procedure: a study of 14 cases

Hallux varus occurs most frequently as a result of excessive surgical correction of musculoligamentous imbalance around the metatarsophalangeal (MTP) joint of the great toe (lateral release and medial capsuloligamentous tensioning). If untreated, the condition may lead to motion loss and degenerative arthritis. In this series, 14 cases of hallux varus were treated. Medial arthrolysis was done in each case. In five cases, reconstruction of the lateral ligament (with a 1.5-mm Ligapro suture), using a new technique, accompanied the medial release. Arthrodesis of the MTP was done in nine cases treated when there was already stiffness and arthrosis. According to a 100-point scoring system, the results were excellent in 56% and good in 44% of the MTP joint arthrodesis cases. Results were excellent in 100% of the mobilizing technique cases using Ligapro suture.
