The Ludloff osteotomy: a critical analysis.
Fourteen Ludloff (oblique shaft) osteotomies were performed to reduce the first intermetatarsal angle on 12 female patients whose average age was 47 years. Average reduction of the first intermetatarsal angle was 6.5 degrees (postoperative average, 9.4 degrees). Average hallux abductus angle reduction was 16.7 degrees (postoperative average, 13.4 degrees). These reductions were statistically significant (P < or = 0.05). Average first metatarsal shortening was 1.4 mm. No transfer lesions nor lesser metatarsal stress fractures were noted. One patient (a 30+ pack/year smoker) sustained a delayed union. The average American Orthopedic Foot and Ankle rating score was 92.3 out of 100. Average follow-up was 48 months. This procedure is a viable alternative to closing base wedge osteotomies.
