The purpose of this study was to review the long term functional results of patients undergoing treatment for high energy tibial plateau fractures. Between January 1994 and June 2013 our unit managed 105 high energy tibial plateau fractures (Schatzker IV-VI) with an Ilizarov frame. All cases were treated via ligamentotaxis and percutaneous fine wire fixation or with a limited open reduction of the joint surface. A retrospective analysis of all patients that have undergone Ilizarov fixation of a tibial plateau fracture was performed with radiological and clinical functional outcome measurements. We analysed 105 patients with a mean follow up of 93.5 months (range 5–200). The patient group had an average age of 49 years (range 15–87) with 62 patients being male. Fracture pattern was analysed with Schatzker's classification showing 18 type IV, 10 type V and 77 type VI tibial plateau fractures. All fractures had an average time to union of 145 days. Patients had and average range of movement of 117 degrees. Patients undergoing Ilizarov treatment for high energy tibial plateau fractures achieve successful results long term. Definitive treatment should be decided with respect to fracture pattern and the soft tissue envelope. The management aim should be to achieve anatomical reduction and stable fixation to enable early mobilization. Our study confirms the good functional outcomes and low morbidity that can be achieved in high energy fractures treated with Ilizarov fixation.
The purpose of this study was to assess the impact of Ilizarov frame fixation and total contact casting on the complications of Charcot arthropathy. The diabetic charcot foot or ankle is a potentially limb threatening disorder. This progressive disorder is characterised by osteopenia, bone fragmentation and joint subluxation. The risk of significant deformity and osteomyelitis lead to high rates of amputation in these patients. We analysed patients with acute charcot arthropathy attending the Rowley Bristow Unit between 2008 and 2012. We assessed 48 patients with a mean age of 59 years. Mean follow up was 24 months. 12 patients were managed with Ilizarov frame fixation and 36 using total contact casting. The duration of management was determined using serial infrared temperature monitoring to ensure the temperature of the limb normalised before patients were deemed safe to remove their immobilisation. The mean duration of Iliazarov frame fixation was 6.2 months and 5.3 months duration for total contact casting. In the Ilizarov group pin site infections were common and treated with a short course of antibiotics. In total one patient required below knee amputation following Ilizarov frame fixation. No patients suffered with osteomyelitis. We feel that prompt management of acute charcot arthropathy with either total contact casting where appropriate or Ilizarov frame fixation can reduce serious complications of this disorder.
Currently the debate continues in definitive fixation method for complex tibial plateau fractures. The aim of surgical management remains prevention of further damage to the articular cartilage, whilst avoiding iatrogenic risks - Low Risk Surgery (LRS). The purpose of this study was to determine the functional impact, clinical radiological outcome following tibial plateau fractures treated with either external fixation or internal fixation. 124 Schatzker IV-VI tibial plateau fractures were reviewed following surgical fixation. Fractures analysed included 24 type IV, 20 type V and 80 type VI tibial plateau fractures. The majority of Schatzker IV fractures were treated with internal fixation, but 67 of 80 Schatzker VI fractures were treated with the Ilizarov method. The average IOWA knee score, was 86 (16 to 100) and the average range of motion was 133 degrees (60 to 150). There were no differences between the circular fixator group and the internal fixation group in terms of range of motion or IOWA scores. There were comparable functional outcomes and complication rates between both groups. In summary patients with high energy tibial plateau fracture treated with internal or external fixation, have a good chance of achieving satisfactory long term knee function.
Extensor tendon ruptures have been reported in up to 8.8% of patients after volar plating and long screws have been implicated. The dihedral dorsal surface of the distal radius hinders accurate screw length determination using standard radiographic views (lateral; pronation and supination). A ‘dorsal tangential’ view has recently been described, but has not been validated. To validate this view, we mounted a plate-instrumented sawbone onto a jig. Radiographs at different angles were reviewed independently by 11 individuals. Skyline views clearly demonstrated all screw tips, whereas only 69% of screw tips were identifiable on standard views. With screws 2mm proud of the dorsal surface, skyline views detected 67% of long screws (sensitivity). The best of the standard views achieved only 11% sensitivity. At 4mm long, skyline sensitivity was 85%, compared with 25% for standard views. At 6mm long, 100% of long screws were detected on skylines, but only 50% of 8mm long screws were detected by standard views. Inter and intra-observer variability was 0.97 (p=0.005). For dorsal screw length determination of the distal radius, the skyline view is superior to standard views. It is simple to perform and its introduction should reduce the incidence of volar plate-related extensor tendon rupture.
