Comparing proximal and distal metatarsal osteotomy for moderate to severe hallux valgus.

PURPOSE: This study compared results of distal and proximal metatarsal osteotomy for moderate to severe hallux valgus in terms of radiographic correction and functional outcome.

METHODS: We analyzed 125 moderate to severe hallux valgus surgeries. Patients were divided into two groups. Group 1 underwent distal metatarsal osteotomy, and group 2 underwent proximal metatarsal osteotomy. Patients were interviewed for functional scores before and one year after surgery. The anteroposterior (AP) weight-bearing radiography of the foot was taken before and one year after surgery.

RESULTS: There were no significant differences in pain and function after one year in either group. Both groups experienced significant pain reduction and increase in all functional scores. There was significant improvement of hallux valgus and intermetatarsal angle corrections in group 2. There was less improvement in radiographic correction in group 1.

CONCLUSION: Either distal or proximal metatarsal osteotomy is an appropriate pain-relieving procedure and can increase functional outcome in moderate to severe hallux valgus. However, distal metatarsal osteotomy provides lower correction power.
