Intramedullary nailing with reaming to treat non-union of the tibia.
The records of fifty-one patients who were treated by intramedullary nailing with reaming for non-union of the tibia were retrospectively reviewed. The fractures had been treated initially by closed reduction and immobilization in a cast, external fixation followed by immobilization in a cast, fixation by pins incorporated in a plaster cast, minimum internal fixation and immobilization in a cast, dynamic compression plating, or intramedullary nailing with or without reaming. After the initial treatment had failed, intramedullary nailing with reaming was done to gain union. ⋯ In forty-nine (96 per cent) of the fifty-one patients, tibial union occurred at an average of seven months postoperatively. Complications included persistent infection (three patients), acquired infection after intramedullary nailing with reaming (three patients), fracture of the nail that necessitated an additional operation (two patients), shortening of more than one centimeter (two patients), malrotation of more than 15 degrees (one patient), peroneal palsy (one patient), and amputation (one patient). When used to treat non-union of the tibia, intramedullary nailing with reaming can produce union as effectively as other alternatives, while enabling the patient to function more normally without external immobilization or walking aids.

One-stage treatment of congenital dislocation of the hip in older children, including femoral shortening.
We reviewed the results of primary operative treatment in twenty-five patients (thirty-three hips) who were two years or older and had congenital dislocation of the hip. None of the patients had had previous treatment for the dislocation. Preliminary traction was not used in any patient. ⋯ According to the rating system of Ferguson and Howorth, there were seventeen excellent, seven good, and three fair results; one hip had a poor result. It was concluded that children who are two years or older and who have a congenital dislocation of the hip can safely be treated with an extensive one-stage operation consisting of open reduction combined with femoral shortening and, often, pelvic osteotomy, without increasing the risk of avascular necrosis. The limb-length discrepancy that is produced by the shortening does not appear to cause a clinical problem.

Measurement of pressure in the carpal canal before and after endoscopic management of carpal tunnel syndrome.
In forty-six patients who had carpal tunnel syndrome, a technique of continuous infusion, given under local anesthesia and without a pneumatic tourniquet, was used to measure pressures in the carpal canal before and after endoscopic release of the transverse carpal ligament (retinaculum flexorum manus). Pressures were similarly measured in sixteen subjects in a control group. ⋯ The mean pressures improved significantly postoperatively and were in the range of values that were found under each condition for the control group. Measurement of pressure in the carpal canal before and after operation may be useful in diagnosing carpal tunnel syndrome and in determining the effectiveness of endoscopic management.
