Efficacy of calcium sulfate particles combined with allogeneic bone grafting on bone defects after surgery for benign bone tumors of the extremities.

BACKGROUND

Benign extremity bone tumors significantly impact patients' quality of life. While autologous bone grafting increases surgical trauma and donor-site complications, allogeneic bone grafting carries risks of infection and rejection.

OBJECTIVE

To evaluate the efficacy of calcium sulfate (CS) particles combined with allogeneic bone grafting for bone defects following benign extremity bone tumor surgery.

METHODS

This retrospective analysis included 121 patients treated at Honghui Hospital (Jan 2018-Dec 2020). The control group (CG, n=60) received CS artificial bone grafts, while the research group (RG, n=61) received CS combined with allogeneic bone grafts. Outcomes included treatment efficacy, drainage volume, soft tissue swelling resolution time, bone healing time, particle absorption time, residual bone defect rate, complications, limb function at 18 months postoperatively, Pain scores (VPS) of the two groups before and after treatment and quality of life at 6, 12, and 18 months postoperatively.

RESULTS

The RG demonstrated a significantly higher total effective rate compared to the CG. Postoperative drainage volume and soft tissue swelling disappearance time were notably reduced in the RG. Additionally, the RG showed shorter bone healing time and particle complete absorption time, lower residual bone defect rate after artificial bone absorption, and decreased incidence of wound infection and delayed healing. The VAS score of patients in the RG group improved more significantly than that of the CG. Limb function at 18 months and quality of life at 6 and 12 months were significantly better in the RG.

CONCLUSIONS

CS particles combined with allogeneic bone grafting effectively reduces postoperative bone defects, promotes recovery, and improves quality of life in patients with benign extremity bone tumors, warranting clinical promotion.
