Patients

The present study included 87 patients who underwent percutaneous HPS fixation and cementoplasty for the treatment of femoral neck metastasis between May 2008 and Dec 2015 at our institution. These patients were diagnosed with advanced cancer in the bone and/or visceral organs. All patients met the criteria of a Mirels score of >9 for femoral neck metastasis¹², and all required local pain control and mechanical stability. All patients had been evaluated at the surgical conference by means of a multidisciplinary team approach and had been deemed not to be candidates for open surgery because of a poor general condition, with multiple bone metastases or difficulty in stopping chemotherapy. The primary malignant lesions involved the lung (n = 38), breast (n = 20), liver (n = 6), prostate (n = 4), intestine and colon (n = 4), bone marrow (n = 3), kidney (n = 3), brain (n = 2), skeleton (n = 2), gallbladder (n = 2), lymphatic system (n = 1), esophagus (n = 1), and thyroid (n = 1). The present study was approved by the institutional review board of our institution, and informed consent was obtained from the patients.
