Myositis ossificans circumscripta in para/tetraplegics

Area of Science:

• Physical Medicine and Rehabilitation
• Neurology
• Orthopedics

Background:

• Myositis ossificans circumscripta (MOC) is a potential complication in patients with spinal cord injuries.
• Understanding the prevalence and risk factors for MOC is crucial for patient management.

Purpose of the Study:

• To investigate the incidence and characteristics of MOC in patients with paraplegia and tetraplegia.
• To identify neurological factors associated with MOC development.
• To highlight the clinical implications and suggest diagnostic approaches for MOC.

Main Methods:

• Retrospective analysis of 52 cases of MOC among 605 patients with para/tetraplegia.
• Correlation of MOC occurrence with the level and completeness of spinal cord lesions.

Main Results:

• MOC was significantly more frequent after total spinal cord injuries compared to subtotal injuries.
• MOC was not observed in cases with spinal cord lesions above the motor level.
• Traumatic spinal cord injuries showed a higher incidence of MOC than those caused by disc herniation or tumors.
• 25% of patients developed mild hip contractures, and 12% developed severe contractures, leading to complications like decubital ulcers and extended hospital stays.

Conclusions:

• The level and completeness of spinal cord injury are key factors in MOC development.
• MOC can lead to significant functional impairments and prolonged hospitalization.
• A simple diagnostic program is suggested for para/tetraplegics, with routine X-rays deemed unnecessary.
• Further research into causative factors and effective treatments for MOC is essential for improving patient outcomes and social adaptation.
