Facet Joint Arthritis (Spondylarthritis) in Singapore

Lumbar Joint Arthritis

Lumbar Joint Arthritis

In case of significant arthritic changes of the facet joints with hypertrophy of the capsule, hypertrophied facet osteophytes, incomplete spontaneous fusion of the facet joints, and air inclusion, the patients may profit from a facet joint infiltration. If a temporary pain release can be reached, a direct fusion or screw fixation […]

X-Ray

What is X-Ray?

X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, a machines sends are individual x-ray particles, called photons. These particles pass through the body. A computer or special film is used to record the images that are created.

Structures that are dense (such […]

Clinical Evaluation-Radiographic Evaluation

Accurate radiographic evaluation of the fracture of the proximal humerus is essential for diagnosis and treatment. The trauma series is still the standard initial method for evaluating proximal humeral fracture. This consists of anteroposterior (AP) view of the scapula, a lateral, Y-view of the scapula, and axillary view. This series allows evaluation of the fracture […]

Imaging

As with almost every other orthopaedic condition, the clinician should begin by obtaining a complete series of plain film radiographs. For the shoulder, these should include an anteroposterior view, axillary view, and outlet view (or scapular-Y view). We also include a 30-degree caudal tilt view to better assess the acromioclavicular (AC) joint.

Others have described […]

Decision Making and Classification

The primary decision that a sports physician must make when confronted with a thoracolumbar condition is whether the athlete has a significant mechanical and/or neurological instability requiring urgent or emergent stabilization.

The spinal problem can be categorized initially as a high-energy injury, a low-energy injury, or even a no-injury situation. In turn, high-energy injuries to […]

Current Controversies-Initial Radiographic Imaging

On transport to the emergency room, the initial imaging modality to evaluate the cervical spine is plain-film radiography.

Both the NCAA and the Inter-Association Task Force for Appropriate Care of the Spine-Injured Athlete have recommended that initial radiographs be obtained with the helmet and shoulder pads in place (but with the face mask removed). After […]

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 […]

Mallet Finger

Basics Description Mallet finger is a loss of continuity of the conjoined lateral bands at the DIP joint of the finger that results in a characteristic flexion deformity of the distal joint. Mallet finger deformity resulting from the fracture of a child’s distal phalanx usually is a transepiphyseal fracture of the phalanx. Classification is […]

Hip Dislocation

Basics Description Dislocations and fracture-dislocations of the hip are orthopaedic emergencies. Serious, high-energy injuries in which the femoral head becomes completely dislodged from the acetabulum A thorough examination must be performed to assess for other possible injuries. Up to 50% of patients suffer other fractures at the time of injury. Associated acetabular or femoral […]

Hip Arthritis

Basics Description Hip arthritis is caused by loss of the articular cartilage of the acetabulum and proximal femur. As the cartilage is lost, the subchondral bone of the proximal femur and the acetabulum rub, causing pain with ambulation, loss of motion, and disability. General Prevention Low-impact exercise (swimming, biking, walking) Activity modification Weight loss […]
