Local Recurrence After Minimally Invasive Curettage For Primary Giant Cell Tumor of Bone With Perioperative Bisphosphonate Is Comparable to Open Curettage: Retrospective Comparison With 9-Year Follow-Up.

Purpose: To compare the long-term oncological outcome of minimally invasive curettage (MIC) with conventional open curettage (OC).

Methods: We studied patients with primary giant cell tumor of bone (GCTB) of extremities who underwent intralesional tumor curettage and cementation and perioperative bisphosphonates from February 2003 to June 2016. All cases were histology-confirmed diagnoses of GCTB.

Osteonecrosis of the hip: is there a difference in the survivorship of total hip arthroplasty with or without previous vascular iliac bone grafting?

Background: Osteonecrosis of the femoral head (ONFH) is a debilitating condition. Vascularized iliac bone graft (VIBG) is a joint-preserving surgery to improve blood supply to the avascular portion of the femoral head which may delay secondary osteoarthritis and total hip arthroplasty (THA). However, whether VIBG will affect the subsequent THA survivorship and outcomes are still uncertain.

Long-term outcome of vascularized iliac bone grafting for osteonecrosis of femoral head: A retrospective study with 17-year follow-up.

Aims: This study aims to investigate the long-term results of vascularized iliac bone grafting (VIBG) for osteonecrosis of the femoral head (ONFH). The primary outcome is the long-term survivorship of VIBG, using conversion to total hip arthroplasty as an end-point. Secondly, this study will also analyse the patient or disease factors influencing the long-term survivorship of VIBG.
