Summary
Heterotopic ossification affects up to 25% of traumatic spinal cord injury patients, potentially limiting joint mobility. Surgical removal of mature bone deposits is possible after a 14-month maturation period.
Area of Science:
- Orthopedics
- Neurology
- Regenerative Medicine
Background:
- Heterotopic ossification (HO) is a common complication following traumatic spinal cord injury (SCI).
- HO can lead to significant joint stiffness and reduced range of motion in paralyzed limbs.
- Approximately one-third of affected patients experience HO extensive enough to impair function.
Purpose of the Study:
- To review the incidence and impact of heterotopic ossification in traumatic spinal cord injury.
- To outline the criteria and surgical considerations for the resection of heterotopic ossification.
- To establish the timeline for bone maturity necessary for successful surgical intervention.
Main Methods:
- Review of clinical data on patients with traumatic SCI and heterotopic ossification.
- Analysis of factors influencing the development and progression of HO.
- Evaluation of surgical outcomes for heterotopic ossification resection based on bone maturity and anatomical location.
Main Results:
- Heterotopic ossification incidence ranges from 20% to 25% in traumatic SCI patients.
- Mature bone formation, required for successful resection, takes a minimum of 14 months.
- Surgical success is dependent on the maturity of the heterotopic bone deposits.
Conclusions:
- Heterotopic ossification is a prevalent and potentially debilitating complication of traumatic SCI.
- Surgical resection of HO is a viable option when bone deposits are mature (≥14 months).
- Treatment strategies for HO must consider the specific anatomical site and maturity of the ossified tissue.
