Objective. To evaluate the effectiveness of Weil osteotomy in the surgical treatment of the middle hammer toe deformity, accompanied by overload metatarsalgia.

Materials and methods. The results of surgical treatment of hammer toe deformity on 54 feet in 48 patients (46 women and 2 men) aged 31 to 79 years were studied. Median age was 55 [50,5; 61,5] years. Long—term results were studied from 10 to 46 months (median — 31 [24; 36] months). During the examination, the position of the phalanges of the hammer toes in the joints was fixed, the variant of the hammer toe deformity was determined, the passive range of motion in the metatarsophalangeal (MTP) articulation and the forefoot X-ray parameters were measured, the 10-point Visual Analogue Scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society Lesser Toe Scale (AOFAS—II—V) were used.

Results. The pain assessment according to the VAS scale showed a decrease in the median value from 6 [5; 8] points before surgery up to 2 [0; 3] — after the intervention. The median functional state of the forefeet on the AOFAS—II—V scale increased from 40 [30; 45] to 85 [73; 90] points (p < 0.001).

Conclusion. The results of the study indicate the effectiveness of Weil osteotomy in the surgical treatment of central metatarsalgia for the middle hammer toe deformity. The technique provides a significant reduction in pain syndrome
(3 times), creates conditions for easy elimination of hammer toe deformity due to shortening of the metatarsals and decompression of the MTP joint, improves the functional state of the forefoot more than 2 times (according to the AOFAS—II—V scale) and get positive treatment outcomes in 90,8 % of cases.
