The outcome of locking plate fixation for the treatment of periarticular metastases.

Abstract

Periarticular bone metastasis may be treated with endoprosthetic reconstruction. The extensive surgery required may not, however, be appropriate for all patients. Our aim was to establish whether locking plates provide good functional outcomes and a durable construct when used in the management of metastatic disease. Prospective data collection was performed. Twenty one patients underwent surgery for periarticular metastatic tumours. The median duration of followup for surviving patients is one year. There have been no cases of implant failure and no requirement for revision surgery. Pain relief was excellent or good in the majority of patients. Patients who had sustained a fracture prior to fixation had restoration of their WHO performance status. All patients had a dramatic improvement in their MSTS scores. The median pre-operative score was 15% (0%-37%) improving to a median score of 80% (75%-96%) post operatively. Locking plates were found to provide reliable fixation and excellent functional restoration in selected patients suffering from periarticular metastatic bone disease.
