Bone grafting of cryosurgically treated bone defects: experiments in goats.
It is hypothesized that cryosurgically treated bone defects are inappropriate host sites for cancellous bone grafting. The influence of autologous cancellous bone grafting on the healing of cryosurgically treated gap defects of long bones was investigated. A unilateral in vivo experiment was done to study bone strength and graft incorporation in the goat. ⋯ In all goats euthanized at 10 weeks or later, the graft was resorbed. The amount of bone apposition at the site of the cryosurgical lesion and the time at which the defect was bridged were similar in both groups. Autologous cancellous bone grafting does not accelerate healing of cryosurgically treated, stable, diaphyseal defects in the goat.

Perioperative ulnar neuropathy in orthopaedics: association with tilting the patient.
The incidence and causes of perioperative ulnar neuropathy in a prospective series of 203 consecutive patients were examined. Three percent of patients had ulnar neuropathy develop in the entire prospective series. ⋯ There was a highly significant association between a tilted body position on the operating table and development of ulnar neuropathy on the contralateral side. This position rotates the arm internally and places the ulnar nerve at risk for direct compression.
