Summary
Heterotopic ossification (HO) can occur in non-traumatic myelopathies, affecting hip joints. Early diagnosis and intervention are crucial for managing this complication.
Area of Science:
- Neurology
- Orthopedics
- Rehabilitation Medicine
Background:
- Heterotopic ossification (HO) is a known complication of traumatic spinal cord and brain injuries.
- HO is infrequently reported in patients with non-traumatic myelopathies.
Purpose of the Study:
- To investigate the occurrence, clinical features, and risk factors of heterotopic ossification in patients with non-traumatic myelopathies.
Main Methods:
- Prospective study of 114 subjects with non-traumatic myelopathies.
- Clinical assessment, co-morbid condition tracking, and laboratory tests (ESR, serum alkaline phosphatase).
Main Results:
- Seven subjects (6.04%) developed HO, primarily affecting hip joints.
- Common co-morbidities included urinary tract infections, spasticity, and pressure sores.
- Elevated ESR and serum alkaline phosphatase levels were observed in all affected subjects.
Conclusions:
- Heterotopic ossification can occur in non-traumatic myelopathies with similar risk factors and clinical presentations to traumatic injuries.
- A high index of suspicion is necessary for early diagnosis and prompt intervention in these patients.
