In the neonate, Group B beta-haemolytic streptococcal osteomyelitis presents with few inflammatory signs, a mild clinical course, extensive bony destruction, and usually single bone involvement. Onset is late (10 to 60 days after birth) and obstetric trauma appears to predispose to infection. Serotype studies suggest transmission from mother to child at the time of delivery.

Forty-five patients with fractures of the tibial spine were reviewed 3 to 10 years after injury in order to determine the degree of residual laxity of the cruciate or collateral ligaments. After fractures which had been partially or completely displaced, some anterior cruciate laxity was evident, even if patients were asymptomatic. It was also found that an anatomical reduction did not prevent either laxity or some loss of full extension of the knee.

We have reviewed the notes and radiographs of 57 patients with fractures of the proximal humeral epiphysis and examined 30 of them at 2 to 8 years after injury. Regardless of treatment the maximum shortening of the humerus was 2 cm and residual varus angulation was insignificant. Manipulation of a displaced, fresh fracture did not improve the final outcome with respect to humeral growth or function; and open reduction is very rarely indicated.
