Geographic variations in the rates of elective total hip and knee arthroplasties among Medicare beneficiaries in the United States.
We analyzed the variations in the rates of elective total hip and total knee arthroplasties for 1988 in the United States to determine whether the rates correlated with the numbers of surgeons. There were 56,204 total hip arthroplasties and 68,491 total knee arthroplasties, performed in the home states of the patients among all of the Medicare beneficiaries. Medicare beneficiaries include most people who are more than sixty-five years old in the United States and a small proportion of younger people who are eligible for Medicare for other reasons. ⋯ The in-hospital rates of mortality were 0.72 per cent for total hip arthroplasties and 0.45 per cent for total knee arthroplasties. The destinations after discharge from the hospital were similar for the two groups of patients, with more than 65 per cent of the patients being discharged directly to their homes. There were no significant differences among states in terms of the length of stay in the hospital or reimbursement of the hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Indirect reduction and tension-band plating of tibial non-union with deformity.
Thirty-three patients who had a maligned non-union of the tibial diaphysis were treated by limited open exposure, indirect reduction with a femoral distractor, tension-band plating, lag-screw fixation, and autogenous bone-grafting. The time from the injury to treatment of the non-union averaged twenty-nine months. Twenty-two of the fractures were originally open and sixteen fractures had had a previous infection before treatment of the non-union. ⋯ Full motion of the knee was achieved in twenty-nine patients and of the ankle, in eighteen. Complications included four instances of superficial skin breakdowns, one deep infection, and one fracture of the plate. For non-unions of the tibial diaphysis with deformity that are not amenable to intramedullary nailing, the techniques of limited exposure, indirect reduction, tension-band plating, and bone-grafting can yield excellent anatomical and functional results.

Compression plating for non-union after failed external fixation of open tibial fractures.
Fifty non-unions of the tibia that were present in forty-nine patients after external fixation and immobilization in a cast for a high-energy fracture were subsequently treated by compression plating. Initially, there were forty-six open fractures and four closed fractures with a compartment syndrome. Twenty-two non-unions (44 per cent) had early soft-tissue reconstruction (thirteen rotational and nine free flaps). ⋯ A deep infection developed in three patients (6 per cent). Ultimately, forty-eight non-unions (96 per cent) healed without evidence of infection. Plate osteosynthesis is an effective method of treatment for patients who have had an open fracture of the tibia that has failed to unite after external fixation and immobilization in a cast.

Ligamentous reconstruction for posterolateral rotatory instability of the elbow.
Eleven consecutively seen patients who had posterolateral rotatory instability of the elbow joint were managed operatively. The radial collateral-ligament complex was advanced and imbricated in three of them. ⋯ Stability was obtained in ten patients, and seven patients had an excellent functional result. There was one failure in one of the patients in whom the ulnar band of the radial collateral ligament had been reconstructed with the palmaris longus tendon and augmented with a prosthetic ligament.

Reflex sympathetic dystrophy in children. Clinical characteristics and follow-up of seventy patients.
We report on the experience with our first seventy patients who had reflex sympathetic dystrophy and were less than eighteen years old (average age, 12.5 years). In our series, the patients were predominantly girls (male to female ratio, 11:59) and the lower extremity was involved most often (sixty-one of the seventy patients). The average time from the initial injury to the diagnosis was one year, which indicates that the syndrome remains under-recognized in patients in this age-group. ⋯ Thirty-eight of the seventy patients in the series continued to have some degree of residual pain and dysfunction. Reflex sympathetic dystrophy in children differs in presentation and clinical course from the syndrome in adults. It is best treated in a multidisciplinary fashion.
