Giant cell tumors combined with secondary aneurysmal bone cysts are more likely to develop postoperative recurrence: A retrospective study of 256 cases.

Purpose: The epidemiology and clinicopathology of aneurysmal bone cysts (ABCs) secondary to giant cell tumors of bone (GCTBs) have been well documented in the previous literature. However, reports on whether secondary ABCs could affect the postoperative recurrence of GCTBs are rare. This study analyzed the effects of secondary ABCs and other relevant clinical factors on the postoperative recurrence of GCTBs of the extremities.

Analysis of the clinical efficacy of tumor resection methods used in 20 patients with clavicular tumor.

Background: To retrospectively analyze the tumor resection method used in 20 patients with clavicular tumors and evaluate its clinical efficacy.

Methods: A total of 9 patients with clavicular benign tumors underwent intracapsular resection, and 11 patients with clavicular malignant tumors underwent tumor resection from May 2012 to May 2017. Of the 11 patients, 5 underwent clavicular reconstruction using the plate-cement complex.
