Capsular laxity imaging: Definition, Uses, and Clinical Overview

Capsular laxity imaging is the use of medical imaging to evaluate looseness or insufficiency of a joint capsule. In the hip, it helps clinicians look for signs of hip microinstability and related soft-tissue changes. It is commonly used in orthopedics and sports medicine when hip pain and “giving way” symptoms are unclear.

Capsular laxity: Definition, Uses, and Clinical Overview

Capsular laxity means the joint capsule is looser than expected for that joint. The joint capsule is a strong sleeve of tissue that helps keep a joint stable while it moves. In the hip, Capsular laxity is often discussed in relation to pain, “microinstability,” and some sports-related symptoms. Clinicians use the term in exams, imaging interpretation, and when planning rehabilitation or surgery.

Capsular insufficiency: Definition, Uses, and Clinical Overview

Capsular insufficiency means the joint capsule is too loose, too thin, torn, or not functioning well enough to stabilize a joint. In the hip, it can contribute to pain, a feeling of giving way, or mechanical symptoms during movement. The term is commonly used in sports medicine and hip preservation, especially around hip arthroscopy and joint instability. It is also used more broadly in orthopedics to describe inadequate capsular support after injury or surgery.

Capsular closure arthroscopy: Definition, Uses, and Clinical Overview

Capsular closure arthroscopy is the step in hip arthroscopy where the surgeon repairs the joint capsule after it has been opened for access. The hip capsule is a strong sleeve of tissue that helps stabilize the ball-and-socket joint. Closure is commonly considered during arthroscopic treatment for conditions like femoroacetabular impingement (FAI) and labral tears. The goal is to restore the capsule’s supportive function after the arthroscopic work is done.

Capsular adhesion: Definition, Uses, and Clinical Overview

Capsular adhesion is scar-like tissue that causes parts of a joint capsule to stick to nearby structures. It can limit motion and contribute to pain, stiffness, or a “tight” feeling in a joint. In hip care, it is most often discussed after injury or surgery, or in conditions that increase joint inflammation. Clinicians consider it during evaluation of persistent hip symptoms and reduced range of motion.

Cannulated screws femoral neck: Definition, Uses, and Clinical Overview

Cannulated screws femoral neck are hollow (cannulated) metal screws used to stabilize the femoral neck portion of the hip. They are most commonly placed to fix certain femoral neck fractures by holding bone fragments in alignment. The hollow center allows the screws to be inserted over guidewires for accurate positioning. They are typically used in orthopedic trauma surgery and some hip-preservation procedures.

Cannulated cancellous screw: Definition, Uses, and Clinical Overview

A Cannulated cancellous screw is an orthopedic screw designed to fix broken or unstable bone. “Cannulated” means it is hollow so it can slide over a guidewire for precise placement. “Cancellous” refers to spongy bone (often near joint ends), where this screw is commonly used. It is frequently used around the hip, including certain femoral neck fractures and other peri‑articular injuries.

Cam morphology imaging: Definition, Uses, and Clinical Overview

Cam morphology imaging is the use of medical imaging to evaluate a specific shape change at the top of the thigh bone (femur) near the hip joint. It helps clinicians see whether the femoral head–neck junction is less round than expected. It is most commonly used when evaluating femoroacetabular impingement (FAI) and related hip pain. It can be performed with X-ray, MRI, and CT, depending on the clinical question.

Cam morphology: Definition, Uses, and Clinical Overview

Cam morphology is a shape difference at the top of the thigh bone (femur) near the hip joint. It describes a less-round contour of the femoral head–neck junction that can affect hip motion. The term is commonly used when evaluating hip pain and femoroacetabular impingement (FAI). It is usually identified on hip imaging such as X-rays, MRI, or CT.

Cam lesion: Definition, Uses, and Clinical Overview

A Cam lesion is an extra bony prominence at the junction of the femoral head and femoral neck. It is commonly discussed in relation to femoroacetabular impingement (FAI), a cause of hip pain and limited motion. The term is used in orthopedics, sports medicine, and physical therapy to describe a hip shape that can pinch the joint. It may be found on imaging even when a person has no symptoms.
