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 […]

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. […]

Olecranon Fracture

Basics Description The olecranon: Is the proximal bony projection of the ulna at the elbow Articulates with the trochlea of the distal humerus to form the ulnohumeral portion of the elbow joint: This articulation is responsible for flexion and extension of the elbow joint. Is the insertion site of the triceps tendon Contraction of […]

Knee Pain

Basics Description Knee pain has many causes, including pathologic processes in the knee and disorders in distant locations with referral to the knee area. Diffuse or located in a specific region A characteristic history and physical examination frequently narrow the diagnosis. Classification: Traumatic Acquired Risk Factors Athletic activity Obesity Sedentary lifestyle Etiology Traumatic injury […]

Humeral Shaft Fracture

Basics Description Fractures of the diaphysis (shaft) of the humerus Occur at all ages Classification: AO classification method Anatomic location: Proximal 1/3 of the shaft Medial 1/3 of the shaft Distal 1/3 of the shaft Fracture characteristics: Fracture pattern (transverse versus oblique versus comminuted) Fractures may be open or closed. Pathologic (secondary to underlying […]

Hip Avascular Necrosis

Basics Description AVN is osteonecrosis, or death of the bone. All major joints can be affected. In the pediatric population, this condition is called Legg-Calve-Perthes disease and, in general, has a better prognosis than osteonecrosis in the adult. AVN of the hip is osteonecrosis of the femoral head. Synonyms: Osteonecrosis; Aseptic necrosis; Chandler disease […]

Fracture Treatment

Basics Description Fractured or broken bones are a common result of trauma. Treatment of fractures may be with or without surgery and depends on the location and severity of the fracture. Nondisplaced: 1 or both cortices may be involved, but the fracture has not moved. Nondisplaced fractures may be difficult to detect. Displaced: Displacement […]

Computed Tomography

Basics Description CT is a noninvasive diagnostic technique that uses a rotational radiographic source to generate cross-sectional images. CT is particularly advantageous for musculoskeletal imaging when used with multiplanar, volume-rendered reconstruction techniques. Etiology Chronology of development : 1972: Introduction 1974-1976: 1st clinical scanners installed 1980: Became widely available 1985-1986: Introduction of modern applications, such […]

Ankle Fracture

Basics Description Fractures of the distal end of the fibula and tibia are termed ankle fractures. Usually caused by the twisting of the body around a planted foot or a misstep that results in overstressing the ankle joint Severe fractures may result in dislocation of the ankle. 2 fracture classification systems are used currently: […]

A Patient’s Guide to Revision Arthroplasty of the Hip

Introduction

Over the past 30 years, artificial hip replacements have become increasingly common. Millions of people have gotten a new hip joint. The first time a joint is replaced with an artificial joint, the operation is called a primary joint replacement. As people live longer and more people receive artificial joints, some of those joints […]
