Simultaneous calcaneocuboid and talonavicular fusion. Long-term follow-up study.

We examined 16 feet, 33 to 133 months (mean 83) after simultaneous calcaneocuboid and talonavicular fusions performed for a variety of painful disorders of the hindfoot. Objectively, four feet were rated excellent, eight good, four fair and none poor. There was one asymptomatic nonunion of the talonavicular joint. Progressive degenerative arthritis of the ankle was seen in six patients and of the naviculocuneiform joint in seven. Biomechanically, simultaneous calcaneocuboid and talonavicular arthrodesis is better than an isolated talonavicular fusion and is a simple and effective alternative to triple arthrodesis.

Achilles tendinitis.

Achilles tendinitis is a problem encountered frequently. There are certain anatomical and biomechanical principles that help explain the etiology of this entity. We prefer to separate our thinking into "insertional" and "noninsertional" Achilles tendinitis. This is helpful because it allows nonoperative and operative treatment to be problem specific and systematic.

Prospective study of porous-coated anatomic total hip arthroplasty.

Seventy-five uncemented porous-coated total hip prostheses were implanted in 64 patients. The results were reviewed after a mean follow-up period of 47 months (range, 40-64 months). The mean preoperative rating was fair, and the mean postoperative rating was excellent. There were six dislocations. Ten patients had mild thigh pain at one year; by two years, the pain had resolved in six patients. Neither moderate nor severe limp nor significant loosening of beads was observed. Only one patient had progressive radiolucent lines. The high rate of dislocation may be related to a compromise of acetabular position to obtain bony fixation in acetabula early in the series. The clinical results were encouraging.
