We reviewed the rate of revision of unicompartmental knee replacements (UKR) from the New Zealand Joint Registry between 1999 and 2008. There were 4284 UKRs, of which 236 required revision, 205 to a total knee replacement (U2T) and 31 to a further unicompartmental knee replacement (U2U). We used these data to establish whether the survival and functional(More)
BACKGROUND AND PURPOSE There have been few reports of large series of ankle replacements. The aim of this study was to document and evaluate the early results of a nationwide series of total ankle replacements (TARs) performed using second- and third-generation implants. METHODS Records of total ankle replacements performed between February 2000 and(More)
We have investigated whether the use of laminar-flow theatres and space suits reduced the rate of revision for early deep infection after total hip (THR) and knee (TKR) replacement by reviewing the results of the New Zealand Joint Registry at ten years. Of the 51 485 primary THRs and 36 826 primary TKRs analysed, laminar-flow theatres were used in 35.5% and(More)
We have reviewed the rate of revision of fully cemented, hybrid and uncemented primary total hip replacements (THRs) registered in the New Zealand Joint Registry between 1999 and December 2006 to determine whether there was any statistically significant difference in the early survival and reason for revision in these different types of fixation. The(More)
We reviewed the results of reconstruction of 97 upper limbs in a consecutive series of 57 tetraplegic patients, treated from 1982 to 1990. Of these, 49 had functional and eight had cosmetic reconstructions. The principal functional objectives were to provide active elbow extension, hook grip, and key pinch. Elbow extension was provided in 34 limbs, using(More)

A prospective study of 60 patients with quadriceps hematomas was carried out in an attempt to gain a better understanding of the pathogenesis, characteristics, and morbidity of this condition, including those patients in whom ossification occurs. The patients ranged in age from 15 to 25 years; thirty-six were injured playing rugby football. The knee was the(More)
Severe damage to the deep musculature of the thigh was caused by standardized crushing injuries applied to muscle overlying the femora of anesthetized sheep. The injuries caused an acute inflammatory response, with the formation of granulation tissue and, later, extensive scarring. Periosteal bone formed in all cases, in some instances resulting in a spike(More)
A simplified technique of the Sauvé-Kapandji (SK) procedure for disorders of the distal radioulnar joint (DRUJ) is described. The DRUJ is transfixed by a screw but is not formally exposed and fused, the periosteum of the distal ulna is not excised, and the pronator quadratus is not advanced into the pseudarthrosis. Stability of the ulna shaft is obtained by(More)
One hundred and two fractures of the femoral shaft, including eighteen pathological fractures, in 100 patients were internally fixed by closed Küntscher nailing. Sixty-eight fractures resulted from motor vehicle accidents; ten were compound. Seventy-five patients were under the age of thirty years and thirty-four had multiple injuries. Sixty-nine fractures(More)
We reviewed the revision rate and functional outcome of all patients who had a total knee arthroplasty (TKA) after an osteotomy or unicompartmental knee arthroplasty (UKA) on the New Zealand Joint Registry. We used these data to compare the results with primary TKA scores, including comparison of age-matched subgroups. There were 711 patients who had(More)
