Septic Arthritis

Basics Description Septic arthritis is an infection of the joint. In infants, the capillaries penetrating the physeal plate into the epiphysis persist until age 18 months, so spread of infection may occur from the metaphysis indirectly to the epiphysis and then to the joint. Possible irreparable damage to growth plate occurs. Classification: Polyarticular septic […]

Sarcoma (Epitheloid and Synovial)

Basics Description Epithelioid sarcoma: A high-grade soft-tissue sarcoma that is prone to local recurrence, lymph node invasion, and pulmonary metastases. Most common soft-tissue sarcoma of the upper extremity Often confused with granulomatous processes Occurs often in young patients (15-40 years old) Synovial sarcoma: A high-grade malignancy on the soft tissue Occurs in para-articular regions […]

Sacral Insufficiency Fracture

Basics Description Sacral Insufficiency fractures occur in the sacral ala between the SI joints and the neural foramina (Denis Zone 1). The fracture pattern adopts a characteristic H-shape, which is pathonemonic of the condition. It is postulated that the vertical limbs of the H occur 1st, followed by the transverse fracture line. In ~50% […]

Rotator Cuff Injuries

Basics Description Comprises 4 musculotendinous structures (the supraspinatus, infraspinatus, teres minor, and subscapularis) that: Compress the humeral head into the glenoid, allowing the larger muscle groups to function properly Provide muscular balance to the glenohumeral joint Injuries to the cuff can occur at any age, but injuries to people >60 years old are likely […]

Rheumatoid Arthritis

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, […]

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 […]

Osteosarcoma

Basics Description The most common primary malignant bone tumor in children and young adolescents May occur occasionally in older adults but is much less common than chondrosarcoma and MFH May occur within other lesions (secondary sarcoma) such as Paget disease, bone infarcts, and irradiated bone A highly malignant tumor with invasive local growth and […]

Osteomyelitis

Basics Description Osteomyelitis is inflammation or infection of bone. Classification is most commonly based on the timing of onset: Acute: Most often from hematogenous spread: The most common organism in neonates is Staphylococcus aureus, followed by Streptococcus or Gram-negative organisms. In older infants and children, it usually is S. aureus. Subacute: Accounts for 1/3 […]
