We have reviewed 15 patients with infected total knee replacements after removal of the prosthesis, rigorous debridement, antibiotic irrigation, and prolonged systemic antibiotics. Infection was permanently eradicated in all patients; they were left with a functioning limb, on which they could walk with either a caliper (8 patients), a simple splint (3), crutches, or sticks. Three were disappointed because of residual pain. We believe that, if exchange arthroplasty is inappropriate, this procedure is preferable to arthrodesis or amputation for persistent and disabling infection, particularly where constrained artificial joints have been used.

Eight women had 10 toes treated for hallux rigidus by dorsal wedge osteotomy of the proximal phalanx and were reviewed after an average follow-up of 22 years. Five toes were symptom-free, four others did not restrict walking, and only one had required metatarsophalangeal fusion. We conclude that dorsal wedge osteotomy affords long-lasting benefits for hallux rigidus in the adolescent female.

The condition known as delta phalanx (or longitudinally bracketed epiphysis) is a rare congenital anomaly first described in 1964. The deformity consists of a triangular bone with an epiphysis running along the shortened side of the phalanx in a proximal to distal direction, making longitudinal growth of the digit impossible. Isolated hallux varus congenitus due to a delta phalanx of the proximal phalanges of both great toes is extremely rare: there have been only three such cases reported, two of which were in one family--the only report of a familial occurrence of this deformity. This present report details the occurrence of isolated bilateral hallux varus congenitus in four members of one family, a father and his three eldest children. All three children show bilateral delta phalanx of the proximal phalanges of both great toes. There are associated thumb nail anomalies, but no suggestion of polydactylism.
