[The Weil osteotomy in metatarsalgia].

AIM: The purpose of the prospective study is to evaluate the results of Weil osteotomy in painful overloaded central forefoot with dislocation of the MTP joint.

METHOD: 19 left and 16 right feet underwent the Weil osteotomy. In 10 patients the procedure was performed on both feet. In 15 cases only one metatarsal was corrected (the 2 (nd) in 12 and the 3 (rd) in 3 cases), in 17 cases both the 2 (nd) and the 3 (rd) metatarsals and in 4 cases also with the 4 (th) one together. The simultaneous correction of hallux valgus was performed in 19 forefeet. The mean follow-up was 31 months (range, 19 to 41 months).

RESULTS

All patients were satisfied with the result of the operation. The results were excellent in 29 cases (83 %) and good in 6 cases (17 %). The plantar callus disappeared in 27 feet (77 %) and decreased in 8 feet (23 %). In one patient the new callus formed under the head of the neighbouring metatarsal bone. The sufficient MTP joint reduction was found in 31 cases (89 %).

CONCLUSION

It is possible with the Weil osteotomy to correct the metatarsal length accurately according to the preoperative planning. This results in the prevention of new callus formation under the neighbouring metatarsal head. Stable internal fixation allows the early mobilisation of the MTP joint.
