title: Study of straight metatarsal osteotomy for the treatment of plantar callosities.
abstract: OBJECTIVE
  [corrected] To evaluate the outcome of transverse distal metatarsal osteotomies for intractable plantar callosity without hammer toe deformity and associated toe corns.
  
  
  METHODS
  Twenty-five plantar callosities were treated in 19 feet of 13 patients (mean age 48 years, 5 male, 8 female) with transverse distal metatarsal osteotomy.
  
  
  RESULTS
  Twenty-four of the osteotomies united primarily, one after revision. After a 7-year follow-up, 23 of the callosities had healed, two of them after an oblique reosteotomy. Eight hammer toe deformities had developed in the involved rays of four feet. Eight plantar callosities had developed outside the operated rays in five feet. Hallux valgus was a frequent finding in both operated and non-operated feet.
  
  
  CONCLUSIONS
  It seems that transverse distal metatarsal osteotomy is an effective treatment of intractable plantar callosities. Harmful hammer toe deformities and transfer lesions below adjacent metatarsal heads tend to develop over time.
