Summary
This case study highlights a rare bilateral posterior hip dislocation. Initial trauma severity, not intervention timing, may be a key risk factor for avascular necrosis (AVN) after hip dislocation.
Area of Science:
- Orthopedic surgery
- Trauma care
- Vascular complications
Background:
- Bilateral posterior hip dislocations are exceptionally rare traumatic injuries.
- This case involves a 45-year-old male with bilateral posterior hip dislocation and femoral head fractures.
Observation:
- The patient presented with bilateral posterior hip dislocation and comminuted femoral head fractures.
- Initial closed reduction was unsuccessful, necessitating surgical intervention for both hips.
- Complications included left-sided deep vein thrombosis (DVT) and left femoral head avascular necrosis (AVN).
Findings:
- Surgical reduction and internal fixation were performed on both femoral heads.
- Despite earlier intervention on the left, complications predominantly occurred on this side.
- Avascular necrosis (AVN) of the left femoral head developed 14 months post-injury.
Implications:
- The severity of the initial trauma may be a more significant predictor of avascular necrosis (AVN) than reduction timing.
- Delayed reduction exceeding six hours warrants careful consideration of trauma severity as a risk factor for AVN.
- This case underscores the complex interplay between trauma severity, surgical intervention, and complication development in hip dislocations.
