Distal radial fractures are amongst the most common trauma referrals, however controversy remains regarding their optimum management. We undertook a retrospective review of the management of distal radial fractures in our department.

The prospectively maintained trauma database was used to identify patients admitted for operative management of a dorsally displaced distal radial fracture between June 2008 and June 2009. Only extra-articular or simple intra-articular fractures were included (AO classification A2/A3/C1/C2). Operation notes were reviewed to determine the method of fixation. Patients were contacted by post and asked to complete a functional outcome score - Disabilities of the Arm, Shoulder and Hand (DASH). A further 12 patients with similar fractures who had been managed conservatively were also asked to complete a DASH score to provide a comparison between operative and non-operative management.

98 patients were identified - 67 female, 31 male. Mean age was 51 years, range 15-85 years. All patients were at least 1 year post-op.

26 patients had manipulation under anaesthesia (MUA). 48 patients had MUA and K-wire fixation, which was supplemented with synthetic bone substitute in 16 cases. 3 patients had MUA and bone graft and 21 patients had open reduction and internal fixation (ORIF) with a volar plate.

34 correctly completed DASH scores were returned. A lower score equates to a better functional outcome. Mean DASH scores were: MUA 14.8; MUA+K-wire 13.1; ORIF 13.6; conservative 47.1.

This data would indicate that patients with a significantly displaced distal radial fracture have a better functional outcome with operative management to improve the fracture alignment. However, all of the methods of fixation used resulted in similar functional outcomes at one year.

We aim to compare post-operative length of stay and cardiopulmonary morbidity in patients randomised to either navigated or conventional total knee arthroplasty (TKA).

Patients undergoing primary TKA for osteoarthritis were prospectively assigned randomly to either navigation-guided or control groups and blinded to this.

All patients received a PFC implant (DePuy, Warsaw, IN). In the control group the standard femoral intramedullary and tibial extramedullary alignment rod was used. In the navigation group, the BrainLab (Munich, Germany) navigation system was used. All operations were carried out by one of two consultant orthopaedic knee surgeons.

Length of post operative hospital stay and the development of cardiopulmonary complication were recorded and groups compared.

100 patients were recruited (55 control vs 45 navigated). Patient demographics were similar in both groups.

Mean length of stay was 7 days in the control group (range 3-101), 5 days in the navigation group (range 3-10). The mode was 4 days in both groups.

7 patients (13%) stayed for >7 days in the control group, 3 patients (7%) stayed >7 days in the navigation group(p=0.339).

4 patients(7%) required >10 days inpatient stay in the control group, 0 patients required to stay in hospital for longer than 10 days in the navigation group(p=0.069).

The causes for the length of stay exceeding 10 days were pulmonary embolus in 3 patients, and chest infection in 1 patient.

Patients undergoing navigation-guided TKA required shorter post-operative inpatient stays than those undergoing arthroplasty using conventional techniques. Fewer patients in the navigation group required stays longer than 7 or 10 days. The difference in post-operative stay was associated with fewer respiratory complications in the navigated group.
