Do locking plates have a role in orthopaedic oncological reconstruction.
BACKGROUND
Role of locking plate in skeletal reconstruction after resection of bone tumours in Indian patients.


METHODS
Retrospective evaluation of skeletal reconstruction using locking plate in 20 cases of long bone tumours was done. Reconstruction was done in 12 patients following limb salvage surgery, internal fixation of pathological fracture in seven bone tumours and one angiomatous tumour. There were 12 females and 8 male patients.


RESULTS
Average age at the time of surgery was 30.1 years (range 10-58). Minimum follow-up was 11 months (range 11-38). Average time for union in pathological fractures was 4 weeks and 120 days after limb salvage surgery. Vicryl mesh was used to contain the morcellized allograft and cancellous iliac crest in 17 cases. Eighteen reconstructions were intact at an average follow-up of 17 months. Two failed reconstructions included one plate breakage and one screw pull out.


CONCLUSIONS
Use of locking plate does not ensure the bony union at the site of reconstruction but it expedite it and allow early mobilization of joints and weight bearing particularly in Indian patients with late presentations. Careful selection of patients and proper preoperative planning including length of resection are essential for optimal outcomes and to minimize complications. Reconstruction should be supported by cortico-cancellous autograft/allograft for stabilization and union at junction of host and autograft/allograft bone and should be given adequate protection. Vicryl mesh helps in containing the morcellized grafts along the long axis of reconstruction.
