Myositis ossificans revisited - The largest reported case series

Area of Science:

• Orthopedics
• Radiology
• Pathology

Background:

• Myositis ossificans (MO) involves non-neoplastic heterotopic ossification in soft tissues.
• Understanding MO's characteristics is crucial for accurate diagnosis and management.

Purpose of the Study:

• To report the largest case series of Myositis Ossificans.
• To discuss the demographics, diagnostic imaging, and management strategies for MO.

Main Methods:

• Retrospective study of radiology databases from 2007-2020.
• Inclusion of cases diagnosed via X-ray, MRI, and CT.
• Analysis of 68 identified cases of MO.

Main Results:

• A cohort of 68 Myositis Ossificans cases was analyzed.
• The average patient age was 36 years (range 4-84).
• Lower limb muscles were affected in 73% of cases, predominantly the quadriceps.

Conclusions:

• This study presents the largest case series of Myositis Ossificans to date.
• Demographic, diagnostic, and management aspects of MO are discussed.
• Findings contribute to a better understanding of MO in clinical practice.
