Use of extended curettage with osteotomy and fenestration followed by reconstruction with conservation of muscle insertion in the treatment of Enneking stage II locally aggressive bone tumor of the proximal extremities: resection and treatment of bone tumors

Giant cell tumour of the femoral neck: Failure of curettage-cavity filling cementation with screw fixation, a case report

Background

Giant cell tumours are common primary long bone tumours with femoral neck locations infrequent and notorious for pathological fractures. Treatment with simple curettage often results in local recurrence. Aggressive treatment that combines tumour resection with cement filling and internal fixation aims at preserving native joint function.

Case report

The authors intend to illustrate the short falls of such conservative approach through a case report of a femoral neck giant cell tumour in a 37 year old patient. Patient had undergone curettage-cavity filling with screw fixation for a pathological femoral neck fracture. Total hip arthroplasty was undertaken following implant failure and severe hip impairment 3 years after initial surgery.

Conclusion

Intralesional curettage and cavity cementation with internal fixation of giant cell tumour of the proximal femur allows joint preservation. Mechanical failure, local recurrence and degenerative changes hinder long term outcomes especially in the setting of pathological fractures. Further studies are required to delineate the benefits of joint sparing techniques vis-a-vis total hip replacement for giant cell bone tumours of the femoral neck.

Surgical strategy for benign lesions in proximal femur: internal fixation or endoprosthetic replacement

PURPOSE

The purpose of this study was to explore the indications for the two most frequently applied surgical procedures for benign lesions in the proximal femur.

METHODS

We retrospectively reviewed 142 patients with benign lesions in the proximal femur from January 2010 to January 2015. Internal fixation (IF) was adopted in 110 patients, while endoprosthetic replacement (EPR) was applied in 32 patients. Clinical data, including operation time, blood loss, hospitalization time, and hospitalization expenses, were compared between the groups. Limb mobilization was evaluated by the Musculoskeletal Tumor Society Score-93 (MSTS-93) and Harris Hip Score (HHS). Local recurrences and complications were statistically compared.

RESULTS

The average follow-up was 66 months (range 32-84 months). In the EPR group, operation time and hospitalization time were significantly shorter (p < 0.05 and p < 0.05, respectively), while blood loss and hospitalization expenses were significantly higher (p < 0.05 and p < 0.05, respectively). Functional outcomes of the MSTS-93 and HHS were higher at the three week follow-up in the EPR group (p < 0.001 and p < 0.001, respectively) but lower at 6 months (p = 0.031 and p = 0.042, respectively). No differences were observed in the two scores at three  months (p = 0.261 and p = 0.134, respectively). Local recurrence and complication rates were similar in the two groups (p = 0.895 and p = 0.942, respectively).

CONCLUSION

The strategy for benign proximal femur lesions should depend on the site, size, initial diagnosis, and thinning degree of cortical bone. IF and EPR both result in satisfactory local control and functional and radiological results, while EPR is more suitable for aggressive and recurrent lesions and serves as an effective measure after IF failure.
