What Researchers Did
Clinicians reported a 43-year-old woman with pycnodysostosis (a rare bone disease causing fragile bones from osteoclast dysfunction) who had multiple failed surgeries for a femoral fracture, then received 39 HBOT sessions at 2.43 ATA for 120 minutes daily, five days per week.
What They Found
Post-treatment X-rays showed significant fracture healing with improvements continuing at one-month follow-up. Pain scores decreased from 4 to 1 on the visual analogue scale, and quality of life (SF-36) improved substantially. Bone union had not been achieved after multiple surgeries alone.
What This Means for Canadian Patients
For Canadians with rare bone disorders causing impaired fracture healing, HBOT may stimulate healing when surgery repeatedly fails. This highlights HBOT potential role in complex orthopedic cases beyond the most common indications.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
Single case report for an extremely rare disease; the authors acknowledge that a controlled trial in pycnodysostosis is essentially unachievable given how few patients exist worldwide.
