Reactive Arthritis

Basics Description Reactive arthritis (previously called Reiter syndrome) is a form of reactive, inflammatory arthritis classically associated with urogenital, ocular, mucocutaneous, and musculoskeletal involvement. This syndrome is categorized with the group of seronegative arthritides, along with AS, psoriatic arthritis, and enteropathic arthritis. Diagnosis often is overlooked because of its variable presentation and the similarities […]

Radial Head Fracture

Basics Description Radial head fractures: Occur in the proximal 2-3 cm of the radius Are intra-articular fractures (The radial head articulates with capitellum.) Classification : Type 1: Nondisplaced fractures Type 2: Partial head fractures Type 3: Complete head fractures Radial head fractures often are associated with other injuries to the elbow or the forearm. […]

Prepatellar Bursitis

Basics Description Prepatellar bursitis is an inflammation of the bursa in front of the patella. Bursae are located between structures to reduce friction. These sacs are lined with a membranous synovium that produces and absorbs fluid; they are subject to acute or chronic trauma or infection and to low-grade inflammatory conditions such as gout, […]

Posterior Tibial Tendon Rupture

Basics Description PTT dysfunction or rupture is the most common cause of adult acquired flatfoot deformity. A working knowledge of the anatomy and function of the PTT in the normal foot is necessary to understand the pathophysiology that results from dysfunction. Origin: Posterior aspect of the tibia, the fibula, and the interosseous membrane Course: […]

Posterior Interosseous Nerve Entrapment

Basics Description PINS occurs when muscles innervated by the posterior interosseous nerve are affected secondary to entrapment of the posterior interosseous nerve by 1 of several structures. The related, but separate, radial tunnel syndrome is characterized by pain and weakness on the lateral side of the elbow after activities with forceful elbow extension or […]

Phalanx Fracture

Basics Description A phalanx fracture is a break in 1 or more phalanges in the fingers. Finger fractures are classified by: Which phalanx is involved Location within the phalanx Pattern Complexity Open or closed Stable or unstable to motion Epidemiology Fractures of the metacarpals and the phalanges are common. Occur among all ages Common […]

Paget Disease

Basics Description First described by Sir James Paget in 1877 , Paget disease (osteitis deformans) is a bone disorder commonly seen in the geriatric population. As implied by the name osteitis deformans, the involved bone may be severely deformed and enlarged, features that suggest an inflammatory origin. A chronic and slowly progressive disease of […]

Osteochondroma

Basics Description An osteochondroma is a common developmental abnormality of the peripheral growth plate that results in a lobulated outgrowth of cartilage and bone from the metaphysis. Appears as a cartilage-capped bony projection from the metaphysis of long bones Can occur in any bone that develops from enchondral ossification Most commonly occurs in: Long […]

Osteoarthritis

Basics Description The most prevalent form of arthritis May occur in virtually any joint of the body Has no cure and leads to pain and joint dysfunction The end result is loss of articular cartilage with secondary bone changes, including osteophytes, subchondral sclerosis, and subchondral cysts. Classification is by single or multiple joint involvement. […]

Nonunion of Fractures

Basics Description Presence of a postfracture defect in a long bone beyond a reasonable expected healing date, or if no radiographic progression of healing is noted If internal fixation is used to stabilize a fracture, a race exists between fracture healing and hardware failure. Children, because of their active healing potential, rarely develop a […]
