Summary
Bariatric surgery (BS) increases the risk of distal radius fractures (DRFs), particularly after gastric bypass. This fracture risk is not linked to weight loss, time since surgery, or nutritional supplements.
Area of Science:
- Orthopedics
- Bariatric Surgery
- Bone Health
Background:
- Obesity is a significant global health issue.
- Bariatric surgery (BS) is effective for long-term weight loss but may increase fracture risk.
- Distal radius fractures (DRFs) are a concern following BS.
Purpose of the Study:
- To investigate the association between bariatric surgery (BS) and distal radius fractures (DRFs).
- To compare DRF incidence pre- and post-BS.
- To analyze factors influencing DRF risk after BS.
Main Methods:
- Retrospective cohort study of patients with obesity undergoing BS.
- Comparison of DRF and scaphoid fracture incidence in the six years before and after BS.
- Sub-analysis based on surgical type, weight loss, and nutritional supplement intake.
Main Results:
- The incidence of DRFs and scaphoid fractures increased significantly after BS.
- Women experienced a higher incidence of DRFs.
- Restrictive surgery was associated with a lower DRF risk compared to gastric bypass surgery.
Conclusions:
- Bariatric surgery (BS) is associated with an elevated risk of distal radius fractures (DRFs).
- The risk is higher with gastric bypass surgery.
- Fracture risk is independent of age, weight loss, time since surgery, and nutritional supplement intake.
