[Application of debridement and bone autografting combined with proximal femoral anatomical plates for benign tumor in proximal femur].

OBJECTIVE

To explore the clinical effects of debridement and bone autografting combined with proximal femoral anatomical plate in treating benign tumor in proximal femur.

METHODS

From January 2010 to October 2014, 30 patients with benign tumor in proximal femur were treated with debridement, autogenic ilium, autogenic ilium and allogeneic bone implant, and anatomic plate fixation. Among them, there were 13 males and 17 females aged from 12 to 68 years old with an average of 42 years old. The courses ranged from 1 month to 2 years with an average of 9 months. MSTS scoring were observed and compared before and after operation, and also applied to evaluate lower-extremity function. X-ray was examined to evaluate healing of focus. Postoperative complications were observed.

RESULTS

All patients were followed up from 12 to 48 months with an average of 29 months. MSTS score at the final following-up (27.06±2.59) was higher than preoperative (16.44±1.35), and there was significant difference(P<0.05). X-ray at the final following-up showed bone graft fusion, pathological fracture were recover consciously, internal fixation was well, no loosening, deformation and displacement occurred. One case occurred incision fat liquefaction and 1 patient with giant cell tumor of bone relapsed at 13 months after operation.

CONCLUSIONS

Debridement and bone autografting combined with proximal femoral anatomical plate is an effective method in treating benign tumor in proximal femur. It could control tumor, relieve pain, promote function and prevent occurrence of pathologic fractures.
