PIKOR, TD  e  KYTE, RD. Evaluation of peri-articular aggressive benign bone tumours treated with cementation and a locked plate. SA orthop. j. [online]. 2011, vol.10, n.2, pp.48-55. ISSN 2309-8309.

BACKGROUND: Treatment of aggressive benign bone lesions with curettage, burring, cementation and plate augmentation is a widely accepted treatment. We have used the above method utilising a locked plate, rather than conventional plating methods, facilitating immediate stability and early mobilisation. We hypothesised that this joint-preserving method would provide an economic alternative to megaprosthetic joint replacement without compromising good functional outcomes. METHODS: Patients with peri-articular aggressive benign bone lesions were treated with marginal excision, curettage, burring and cementation. This was augmented with a locked plate. Liquid nitrogen was used as an adjunct where feasible. Functional assessment and radiological recurrence was assessed at follow-up using the Musculoskeletal Tumour Society Score (MSTS) and routine X-rays. RESULT: The average MSTS score was 88%. Average follow-up time was 21 months. To date, no revisions have been performed for recurrence or pain and no significant complications have occurred. CONCLUSIONS: Our early results in a small series make us optimistic that this may be an alternative to immediate megaprosthetic reconstruction; furthermore, this may provide a useful intermediate step in the treatment of aggressive benign peri-articular bone tumours with some degree of associated joint deformation without significantly compromising later prosthetic reconstruction.
