Retrospective analysis of the Mau osteotomy and effect of a fibular sesamoidectomy.

The purpose of this study was to evaluate retrospectively outcomes of the Mau osteotomy for hallux abducto valgus deformity. Twenty-two patients were evaluated by the senior author on an average of 14 months (range, 3-34 months) following their surgery. Preoperative and postoperative intermetatarsal (IM) and hallux abductus (HA) angles were evaluated as well as range of motion of the first metatarsophalangeal joint and patient satisfaction. The mean preoperative IM and HA angles were 16.1 degrees and 35.8 degrees. The mean reduction in IM and HA angles was 10.5 degrees and 23.5 degrees, respectively. Joint range of motion was 58 degrees of dorsiflexion (range, 42 degrees-80 degrees) and 11 degrees of plantarflexion (range, 0 degree-20 degrees). There were no cases of delayed healing or avascular necrosis. There were two patients (9%) with radiographic values consistent with hallux varus; however, neither patient had a clinical appearance of hallux varus and neither patient was displeased with the outcome. Ninety-one percent of patients returned to a soft shoe or sneakers in an average of 5.1 weeks following surgery. Eighty-two percent of patients had no pain at the time of their evaluation, and 96% of patients stated they were satisfied or very satisfied with the surgery. Comparing the subgroup of patients who underwent a Mau-Reverdin procedure with another subgroup undergoing a Mau-Reverdin fibular sesamoidectomy, there was a 3.7 degrees greater reduction of IM angle and 6.7 degrees greater reduction in HA angle in the subgroup with the fibular sesamoidectomy.

Flap coverage of a chronic hallux ulcer.

For nonhealing, noninfected plantar ulcerations of toes, flap coverage can be a viable alternative, providing there is adequate vascular supply to the digit. This article presents an interesting case, wherein the digital ulcer was covered with a flap from the same toe. The flapped area was then covered with a skin graft.

A retrospective analysis of distal Chevron and Basilar osteotomies of the first metatarsal for correction of intermetatarsal angles in the range of 13 to 16 degrees.

A retrospective study was performed for Austin (Chevron) and basilar type osteotomies of the first metatarsal in patients with preoperative intermetatarsal angles in the range of 13 to 16 degrees. Results indicated better radiographic correction for both groups than in previous studies. When comparing the results for the Chevron and basilar groups, the radiographic results were almost identical, but the Chevron group appeared to have a slightly better subjective result with less complications of metatarsalgia and callus formation and a better range of motion. Comparing intermetatarsal angle correction as a function of the preoperative hallux adductus, no definitive conclusions were made. However, the trend appears to have reduced correction with higher hallux abductus angles.
