Clinical and functional outcome after partial or total claviculectomy without reconstruction for oncologic causes

Background: To achieve clear margins in rare malignant clavicular neoplasms, claviculectomy may become necessary. This study aimed to review clinical, functional, and oncologic outcomes following partial or total claviculectomy without reconstruction. Methods: This study retrospectively included 15 patients from 2 tertiary sarcoma centers (mean age, 42.6 +/- 20.3 years; 66.7% male patients). The median length of clinical and oncologic follow-up was 48.0 months (interquartile range [IQR], 24.0-83.5 months). Func-tional follow-up (Musculoskeletal Tumor Society score and QuickDASH score [short version of the Disabilities of the Arm, Shoulder and Hand questionnaire]) was available in 9 patients at a median of 36.0 months (IQR, 20.0-100.0 months).Results: Of the 15 patients, 7 underwent total claviculectomy; 5, partial lateral claviculectomy; and 3, partial medial claviculectomy. No postoperative complications emerged. The median Musculoskeletal Tumor Society and QuickDASH scores at latest follow-up amounted to 26.0 points (IQR, 24.0-29.0 points) and 18.0 points (IQR, 11.0-22.0 points), respectively. Notably, scores tended to be lower in patients who underwent total claviculectomy (n = 2) in comparison to partial claviculectomy (n = 7).Conclusion: Satisfactory clinical and functional results can be achieved following partial or total claviculectomy without reconstruc-tion, with a low complication rate and acceptable mid-to long-term function.
