Talus Fracture

Basics Description The talus, a small bone in the hindfoot: Articulates with the calcaneus and the remainder of the midfoot bones Supports the body’s weight and distributes the body’s forces to the foot Is critical to proper function of the foot Is covered (~60%) with articular cartilage Is vascularly supplied by vessels through a […]

Slipped Capital Femoral Epiphysis

Basics Description SCFE is a disorder of the hips of adolescents or preadolescents in which the femoral head is displaced relative to the rest of the femur. The femoral head remains in the acetabulum. Most notable features: The outward rotation of the lower femur and leg and a limp Classification: Stable versus unstable (1): […]

Skeletal Scintigraphy

Basics Description Skeletal scintigraphy is a nuclear medicine imaging method for bone disease. Advantages: High sensitivity for early detection of disease Whole body survey Disadvantage: Limited specificity Diagnosis Signs and Symptoms Indications Whole body skeletal scintigraphy: Primary bone tumors Osteomyelitis Joint prosthesis pain Occult fractures Stress fractures and shin splints Spondylosis Reflex sympathetic dystrophy […]

Shoulder/Proximal Humerus Fracture

Basics Description The proximal humerus consists of the articular surface of the shoulder joint and the attachments of the rotator cuff to the greater and lesser tuberosities. Most of the blood supply to the humeral head comes from the anterior humeral circumflex branch of the axillary artery. >90% of proximal humeral fractures result from […]

Shoulder/Glenohumeral Arthritis

Basics Description Progressive loss of glenohumeral joint space with thinning of articular cartilage, formation of osteophytes, and progressive deformity Epidemiology Females are more likely than males to have primary glenohumeral osteoarthritis. Patients >60 years old are more likely to have it than are younger patients. Incidence ~0.4% in the general population Can reach 4.6% […]

Osteochondritis Dissecans of the Knee

Basics Description A pathologic joint entity of localized bone necrosis with overlying cartilage injury Osteochondritis dissecans primarily affects the knee, but it is also seen in the hip (in late Legg-Calve-Perthes disease), elbow, and ankle. Osteochondritis dissecans occurs primarily in the 2nd decade of life, but it also is seen in children and older […]

Musculoskeletal Radiography

Basics Description Plain radiography has been the primary musculoskeletal imaging technique for >100 years. X-ray beams generated by an x-ray tube pass through the body part to be imaged, and differential absorption and scattering of the x-ray beams occur. The exiting beam carries information about the density of the material traversed. This information is […]

Intertrochanteric Hip Fracture

Basics Description Fractures of the proximal femur located between the greater and lesser trochanters and external to the capsule of the hip joint The greater and lesser trochanters may be avulsed as separate fragments. Many classification systems have been developed that are unreliable in identifying fracture types, but in general, they are classified as […]

Intercondylar Elbow Fracture

Basics Description Intra-articular fracture of the distal humerus, which may occur with a supracondylar fracture Biomechanically and anatomically, the distal humerus forms a triangle composed of a medial column and a lateral column that support the articular surface of the trochlea. The trochlea articulates with the ulna. The capitellum is the part of the […]

Hip Replacement

Basics Description Many forms of arthritis lead to destruction of the articular cartilage of the hip joint, resulting in pain and loss of function. End-stage arthritis can be treated with surgical replacement of the joint. Elderly patients may have a greater risk of cardiac complications and more associated medical problems than younger patients. Patients […]
