The bacteriology of bone allografts.
We report the contamination rate in the Cambridge bone bank of 35 consecutive allograft specimens, all harvested in a clean-air environment, using a strict aseptic technique and antibiotic cover. Five of 27 femoral heads taken from living donors and three of eight massive allografts taken from cadavers were found to be contaminated. The contaminated femoral heads were discarded. All massive allografts were rendered sterile by gamma-irradiation. It is important to exclude bacteriological contamination of harvested and banked bone.
Seasonal variation in the incidence of congenital talipes equinovarus.
A review of 77 neonates who presented with congenital talipes equinovarus over a seven-year period revealed an increase in the condition amongst babies born in the winter quarter. This finding was particularly apparent among the less severe cases of club-foot. Possible reasons for this seasonal variation are discussed.
Hip arthroscopy.
Arthroscopy has become an established part of orthopaedic surgery but arthroscopy of the hip is new. It is being increasingly performed in the USA and Japan, and its use now in the UK has highlighted its advantages in the treatment of many diverse orthopaedic conditions.
