Aims

Fractures of the distal femur can be challenging to manage and are on the increase in the elderly osteoporotic population. Management with casting or bracing can unacceptably limit a patient’s ability to bear weight, but historically, operative fixation has been associated with a high rate of re-operation. In this study, we describe the outcomes of fixation using modern implants within a strategy of early return to function.

Patients and Methods

All patients treated at our centre with lateral distal femoral locking plates (LDFLP) between 2009 and 2014 were identified. Fracture classification and operative information including weight-bearing status, rates of union, re-operation, failure of implants and mortality rate, were recorded.

Impaction bone grafting has become an established technique in restoring acetabular and femoral bone stock loss during hip replacement surgery. This study presents our preliminary results using this technique to restore acetabular bone stock loss during cemented total hip replacement, with particular reference to the use of a preformed perforated metallic mesh to contain major acetabular defects.

In 52 patients (55 hips), acetabular reconstruction with impaction bone grafting was undertaken during total hip replacement (7 primary and 48 revision, of which 13 had previously undergone multiple revisions). The mean age at the time of surgery was 68 (range 34 to 88). In 31 cases (30 segmental or combined acetabular deficiencies, and one case of pelvic discontinuity) a pre-formed stainless steel mesh was utilised to contain the impacted morsellised bone graft. There were no perioperative deaths or deep infections and few complications (2 non-recurrent dislocations and 2 deep vein thromboses). At a mean follow-up of 40 months (range 18 to 91 months) there have been no revisions for any reason. Three patients who died before a minimum follow-up of 18 months have been excluded. Of the 49 patients (52 hips) remaining, clinical hip scores (Merle d’Aubigne and Postel) averaged 5.3 for pain, 4.2 for walking ability, and 5.3 for range of movement (with 16 patients in Charnley group A, 14 in group B, and 19 in group C). There was one case of radiographic loosening, with a radiolucent line > 2mm diameter in all 3 zones of DeLee and Charnley, although the cup has not migrated and the patient remains pain-free. All other cases show radiographic changes suggestive of ongoing graft incorporation.

We consider that the use of preformed metallic meshes extends the scope of impaction bone grafting to include cases where major segmental acetabular deficiencies are encountered, allowing restoration of bone stock and an anatomical centre of hip rotation, with encouraging preliminary clinical and radiological results.
