The aim of this study was to determine whether the rates of revision
for metal-on-metal (MoM) total hip arthroplasties (THAs) with Pinnacle
components varied according to the year of the initial operation,
and compare these with the rates of revision for other designs of
MoM THA. Data from the National Joint Registry for England and Wales included
36 mm MoM THAs with Pinnacle acetabular components which were undertaken
between 2003 and 2012 with follow-up for at least five years (n
= 10 776) and a control group of other MoM THAs (n = 13 817). The
effect of the year of the primary operation on all-cause rates of revision
was assessed using Cox regression and interrupted time-series analysis.Aims
Patients and Methods
We report the management and outcome of 35 lower limb fractures with associated severe vascular injuries treated over a 15-year period. Limb survival was related to the period of ischaemia. Management of the fractures by immediate open reduction and internal fixation was associated with a higher amputation rate than either external fixation or simple splintage, particularly for upper tibial injuries. External fixation is recommended as the method of choice for the stabilisation of the skeletal injury. A selective policy is advised for fasciotomy.
We report a prospective, randomised, controlled trial of 50 severely displaced comminuted Colles' fractures treated by either external fixation or manipulation and plaster. Each patient was assessed radiographically throughout treatment, and functionally by an independent observer at three and six months. The functional result correlated with the anatomical result, which was significantly better in patients treated by external fixation. This resulted in significantly improved function especially in young patients, and also a lower complication rate. We recommend the use of external fixation for young patients with comminuted displaced Colles' fractures unless manipulation and plaster show excellent reduction.
