Physical for OA (general, knees, hands, hips)
Joint line tenderness is common in hands and knees.
Joints may have crepitus, decreased range of motion (ROM), effusion, and atrophy of surrounding muscles.
In knees, involved compartments can include medial (most common), patellofemoral, and/or lateral, so accurate palpation is important. Effusion and trace joint warmth are common in acute flares.
In hands, may see nodules in the DIP and PIP joints, termed Heberden and Bouchard nodes, respectively
In hips, decreased and painful internal rotation are early signs, and tenderness over the anterior joint line is a later finding.
Ix for OA
X-ray characteristics include osteophytes, joint space narrowing, subchondral sclerosis, and cyst formation
Thumb CMC joint: true AP (Robert) view of the thumb, wrist AP, and oblique
Hands: AP and lateral
Shoulder: true glenohumeral AP (Grashey) view most sensitive
Knee: Weight-bearing AP in 20 to 45 degrees of flexion (Rosenberg view) is most sensitive and accurate for the medial and lateral compartments. Supine lateral and sunrise or merchant views are best for patellofemoral compartment.
Hip: Weight-bearing anteroposterior (AP) films are most sensitive.

What is myositis ossificans?
A localized, nonneoplastic, heterotopic ossification that develops in muscle from physical trauma
Anterior muscle groups of the thigh and arm are most frequently affected but may occur at any site
Osteoblasts proliferate inappropriately in a healing muscle hematoma and lay down bone over a period of weeks to months.
Bone maturation usually takes 6 to 12 mo to complete.
Once ossification takes place, little can be done to accelerate the resorptive process, which may take months to years.
Average duration of symptoms related to myositis ossificans (MO) is 1.1 yr.
