[Corrective possibilities by subcapital metatarsal osteotomy in the management of hallux valgus and metatarsus primus valgus].

The extent of correction achievable by inclined subcapital osteotomy of the metatarsus I. was studied in 100 cases of the deformation. The different angular values and dimensions were compared in the X-ray plates taken pre- and postoperatively and the clinical changes of the patients were evaluated on the basis of subjective complaints and objective symptoms. The angular limit values of the performability of osteotomy were determined. In deformations larger than the limit values wedge and half-wedge osteotomy, basisosteotomy, respectively, are the expedient methods.
