Eighty six subtalar arthrodeses performed between 1985 and 1996 for complications associated with intra-articular calcaneal fractures were retrospectively evaluated. Patients were divided into three Groups: (I) 59 patients with calcaneal malunions (II) 13 patients with failed open reduction and internal fixation, and (III) eight patients undergoing open reductions and primary fusion for highly comminuted fractures. In each scenario, internal fixation was achieved with cancellous lag screws. ⋯ Scores were similar for all three groups and for the various types of reconstructive procedures used. No correlation was found between postoperative talar declination angle and the AOFAS ankle-hindfoot score. Worker's compensation patients tended to have a poorer clinical outcome.

Case Reports
Bizarre parosteal osteochondromatous proliferation (Nora's lesion) of the sesamoid: a case report.
We report the a case of Nora's lesion (Bizarre Parosteal Osteochondromatous Proliferation) of the sesamoid. A 32-year-old woman presented with a painless, enlarging mass of two years duration on the plantar aspect of the first metatarsophalangeal joint of the left foot. ⋯ The aggressive growth of this lesion may suggest a neoplasm clinically. Histological features, however, are those of a reactive lesion.

Three purposes of this study were to: 1) describe the sustentaculum tali in relation to surrounding structures, 2) identify its radiographic projection onto the lateral calca neus, and 3) determine optimal angles for screw placement. Twelve cadaver specimens were used. The length a width of the sustentaculum was measured. ⋯ The angles required to pass a pin from point A into the sustentaculum were determined. The sustentaculum projected as a triangular/elliptical structure on the lateral radiograph. It was superimposed on the anterior portion of the posterior facet.
