Heard of Muscle Ossification? Let us help you if you are suffering from Myositis Ossificans.

Myositis Ossificans

  • Myositis Ossificans is a benign, meta-plasmatic, mostly self-limiting process in which bone or bone-like tissue formation takes place in skeletal muscle.

  • It occurs mostly in large skeletal muscles such as quadriceps, brachialis & adductor of thigh.

  • It may arise with or without trauma.

  • But its common in young active athlete after a single traumatic injury



It is also known as:

  • Localized Non-neoplastic Bone

  • Myositis Ossificans Traumatica

  • Myo-osteosis

  • Myositis Ossificans Circumscripta

  • Traumatic Ossifying Myositis

  • Ossifying Hematomaaematoma

Causes

Based on the cause, it is classified into:

  • Myositis Ossificans Traumatica (MOT)

It is also called as the non-hereditary myositis ossificans (associated with burns, hemophilia and neurological disorders)

  • Myositis Ossificans Progressiva (MOP)

It is also called Fibroplasia Ossificans Progressiva (FOP).


Its exact cause is unknown but mostly it's an error in the healing process where normal muscle cells known as fibroblast are replaced by immature bone cells.

paraplegics are usually prone, even without evidence of trauma.


Symptoms

  • Pain-Aching type of pain lasting for more time than in case of a simple muscle contusion.

  • Swelling-Localized swelling on the anterior thigh or in some cases it may be in the whole limb.

  • Decrease ROM-Gradual loss of ROM (Range of motion)

  • Pain with passive stretching.


MO should be suspected under the following circumstances:

Worsening of symptoms after 2-3 weeks accompanied by loss of knee flexion

Persistent swelling


Medical Management:

NSAIDs, rest, and exercise therapy.


Surgical Management:

Operative removal of the ossification is only indicated for progressive disease or persistent cases in which conservative treatment has not been successful


Physical Therapy Management

  • Due to the rarity of MO of the quadriceps, little evidence exists to guide treatment.

  • Many case studies and reviews advocate an initial period of stretching, range of motion & gentle exercise (ex. isometric quadriceps contraction and terminal knee extension)

  • This should be followed by the addition of more aggressive strengthening, proprioceptive retraining, aerobic conditioning, and return to activity.

  • A small number of case studies suggest that Extracorporeal Shockwave Therapy (ESWT) may be an effective adjunct to traditional conservative measures.
