What Researchers Did
Researchers combined data from 7 studies to determine whether HBOT improves how autologous bone grafts, bone taken from the patient's own body, integrate after transplant surgery.
What They Found
HBOT produced a moderate-to-strong effect on bone graft integration overall (standardized mean difference of 1.476, 95% CI: 0.814–2.138). In orthopedic surgery specifically, the effect was even stronger (SMD 1.995) with very consistent results across studies (I²=3.4%). Results for craniofacial applications were less consistent, with one cranial study showing a negative result.
What This Means for Canadian Patients
For Canadians undergoing bone reconstruction, such as spinal fusion, limb salvage, or orthopedic procedures requiring bone grafts, HBOT added to their recovery plan may substantially improve how well the transplanted bone takes hold and heals. Orthopedic patients appear to benefit the most.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
Most of the analyzed studies used animal models, and the substantial variation in overall study results (I²=77%) limits confidence in applying findings directly to human patients.
