Disorders of the hallucal interphalangeal joint.

Most clinical presentations of the hallux concern the metatarsophalangeal joint; however, interphalangeal joint (IPJ) pathology also may be clinically significant. This article reviews conditions that commonly affect the hallucal IPJ and the appropriate treatment.

Avascular necrosis of the first metatarsal head.

Avascular necrosis of the first metatarsal head is uncommon. It is most often seen following a distal metatarsal osteotomy for hallux valgus. In this setting surgery has usually involved extensive periarticular dissection as well.

Interphalangeal joint arthrodesis of the lesser toes.

Fusion of the PIP joint of the lesser toes provides sound correction of deformity of that joint. Fusion is achieved reliably in most cases and fibrous ankylosis is well tolerated in those that fail. Patients at the extremes of the age scale are perhaps less tolerant of the procedure; complaints include poor cosmesis and subjective lack of control of the toes [18].

Pedobarographic and musculoskeletal examination of collegiate dancers in relevé.
