Between 1993 and 2000 we implanted 200 cementless, mobile-bearing STAR total ankle replacements. None was lost to follow-up for reasons other than the death of a patient. The mean follow-up was for 46 months (24 to 101). A complication requiring further surgery developed in eight ankles and 14 were revised or fused. The cumulative survival rate at five years was 92.7% (95% CI 86.6 to 98.8) with time to decision to revision or fusion as an endpoint. The most frequent complications were delayed wound healing and fracture of a malleolus. These became less common with experience of the operation. The radiological appearance of the interface of the tibial implant was significantly related to its operative fit and to the type of bioactive coating.

ObjectiveTo determine if the detection of physical abuse in young children with fractures is of uniform high standard in the East Anglia Region of the UK, and whether we can identify areas for improvement in our detection of high-risk groups.DesignMulticentre retrospective 4-year study.Setting7 hospitals across the East Anglia Region of Britain (East Anglia Paediatric Physical Abuse and Fractures study).ParticipantsAge groups and fractures indicated as being at higher risk for physical abuse (all children under 12 months of age, and fractures of humerus and femur in children under 36 months of age).Outcome measuresOur criterion for physical abuse was the decision of a multiagency child protection case conference (CPCC).ResultsProbability of CPCC decision of physical abuse was highest in infants, ranging from 50% of fractures sustained in the first month of life (excluding obstetric injuries) to 10% at 12 months of age. Only 46%–86% of infants (under 12 months) with a fracture were assessed by a paediatrician for physical abuse after their fracture. Significant variation in the use of skeletal surveys and in CPCC decision of physical abuse was noted in children attending different hospitals.ConclusionsIt is a concern that significant variation between hospitals was found in the investigation and detection of physical abuse as confirmed by CPCC decisions. To minimise failure to detect true cases of physical abuse, we recommend that all high-risk children should be assessed by a paediatrician prior to discharge from the emergency department. Our proposed criteria for assessment (where we found probability of CPCC decision of physical abuse was at least 10%) are any child under the age of 12 months with any fracture, under 18 months of age with femur fracture and under 24 months with humeral shaft fracture (not supracondylar).

The indications for using abduction splints in developmental dysplasia of the hip (DDH) are not clearly defined. In this study, the authors prospectively evaluated 797 babies born between 1996 and 1998 as part of a limited targeted ultrasound screening program. In the first group (1996-97), babies with clinical hip instability at first scan were placed in a Pavlik harness. In the second group (1998), only babies who had persistent instability at 2 weeks were splinted. Children with persistent major dysplasia at 9 weeks were splinted in both groups. The splintage rate was 1.6/1,000 live births in the first group and 0.8/1,000 live births in the second group. The rate of surgery for DDH did not increase despite a significant decrease in the number of babies being splinted. This study demonstrates that a splintage rate as low as 1.3/1,000 live births (average rate for 1996-98) can be achieved without adversely affecting the outcomes following treatment of DDH.
