Twenty-eight ankles in twenty-seven patients (average age 28) underwent the Gould modification of the Brostrom repair for symptomatic lateral ankle instability. Fifty-four percent were high level professional ballet dancers, 35% were recreational athletes, and 11% were nonathletes. Follow-up averaged 64.3 months (range 30-132 months). Of the 28 operations performed, there were 26 excellent results, one good result, and one fair result. All the professional dancers obtained excellent results. There were no failures, stretch-outs, re-dos, or complications. This operation is believed to be an excellent choice for the dancer, athlete, or nonathlete who needs a stable ankle with a full range of plantarflexion and dorsiflexion and normal peroneal function.

Ten adult cadaver feet, three neonatal feet, and the feet of two fetuses were dissected to investigate whether an anatomical continuity exists between the fibers of the Achilles tendon and the plantar fascia. Histologic sections of the feet were done in three age groups: neonate, persons in their mid-20s, and the elderly. As the foot ages, there appears to be continued diminution of the number of fibers connecting the Achilles tendon and plantar fascia. The neonate has a thick continuation of fibers, while the middle-aged foot has only superficial periosteal fibers that continue from tendon to fascia. The elderly feet show simply an insertion of fibers of both structures into the calcaneus with periosteum in between.

Five patients with osteoid osteomas of the talar neck were treated at the Hospital for Special Surgery between 1981 and 1992. The course of care leading to definitive diagnosis and treatment was reviewed. All five of the patients had night pain relieved by aspirin or nonsteroidal anti-inflammatory drugs. One of the five reported associated trauma. The average time from onset of symptoms to correct diagnosis was 2.5 years. Juxta-articular osteoid osteoma can cause a small spur that resembles a traction spur on the neck of the talus. Anterior ankle impingement was the most common misdiagnosis. Initial treatments included arthroscopic spur debridement or synovectomy, casting for fracture, and repeated nerve blocks for reflex sympathetic dystrophy. The five patients were cured by en bloc excision of the lesion. In the diagnosis of osteoid osteoma, a history of relief of pain with aspirin is important. Plain radiographs and a bone scan are useful. Fine cut computed tomography scanning or magnetic resonance imaging are the best studies for making a definitive diagnosis. Localization by computed tomography guided needle placement or intraoperative radionuclide scanning are recommended to find the lesion for excision. Intraoperative radiographs of the excised lesion should be used to confirm complete removal.

Dislocation of the fat pad of the heel is a relatively rare but potentially devastating injury. An understanding of the anatomical anchoring of the heel pad and its mechanical function can lead to a surgical procedure to restore stability to the heel pad.
