Between March 1969 and May 1978, 36 babies sustained birth injuries of the brachial plexus at the National Women's Hospital, Auckland, New Zealand. This gives an incidence of 0.87 per 1000 live births. Nearly 80 per cent of these children had made a complete recovery by the age of 13 months, while none of those with significant residual defects has severe(More)
The collagen fibrillar architectures in the general matrix of cartilage slices removed from both normal and osteoarthritic femoral heads were examined by both differential interference light microscopy and scanning electron microscopy. Whereas the normal general matrix contained a finely differentiated pseudo-random weave of fibrils developed from an(More)
A biomechanical investigation of the dynamic shear failure of the osteochondral region of immature, adolescent, and mature bovine cartilage bone laminates was performed. The osteochondral junction was loaded in pure shear under impact conditions through the cartilage layer only. The results indicate the adolescent tissue fails at a nominal shear stress of(More)
We performed a randomised, prospective trial to evaluate the use of unreamed titanium nails for femoral fractures. Of 48 patients with 50 femoral fractures 45 were followed to union; 23 with an unreamed and 22 with a reamed nail. The study was stopped early because of a high rate of implant failure. The fractures in the unreamed group were slower to unite(More)
Osteomyelitis developed at closed fracture sites in two children. The infection responded to antibiotic therapy, and the fractures healed without chronic infection developing, impairment of bone growth, or loss of function. It is rare for a closed fracture to develop acute hematogenous osteomyelitis, but the diagnosis should be considered in a child with a(More)
In a retrospective study of 19 patients treated with bone grafts of the tibia, nine had ankle symptoms. Eight of the nine had synostoses between the tibia and fibula. Inasmuch as a synostosis is prone to develop after a posterolateral graft, this procedure should be used only when there is an unsatisfactory skin cover for the anterior surface of the tibia.
Thirteen patients with ruptures of the calcaneal tendon diagnosed more than four weeks after injury were reviewed. Eleven patients had operative reconstruction with tendon shortening and the postoperative follow-up ranged from one to seven years. Isometric and isokinetic measurements, as well as the strength of the triceps surae, all compared favourably(More)
BACKGROUND There are a number of factors relating to the host, bacteria and wound that are important in the development of wound infection. The effect of the surgeon sweating has not been previously reported. METHODS Ten surgeons performed a mock total hip joint operation under sterile conditions while not sweating and then repeated the operation while(More)
