The Impact of Unilateral Transfemoral Amputation on Lumbar Bone and Muscle Quality.

Objective: To examine the long-term perioperative changes in lumbar bone density, muscle size and fatty atrophy, and facet degeneration after transfemoral amputation (TFA).

Design: All patients who underwent TFA at an academic center between 2002-2022 were retrospectively identified. Patients were required to have preoperative and postoperative CT (>1 year) and regularly utilize a prosthesis.

Basics of Shoulder Arthroscopy Part IV: Diagnostic Arthroscopy in the Lateral Decubitus Position.

Shoulder arthroscopy is a versatile method for treating a variety of shoulder pathologies in a minimally invasive manner. Typically, it is performed with the patient positioned in a beach-chair or lateral decubitus position with the latter being conventionally preferred for shoulder instability work given the use of traction and creation of a distracted joint. This allows ideal visualization and accessibility of the anterior, inferior, and posterior aspects of the glenoid, labrum, and axillary pouch.

Basics of Shoulder Arthroscopy Part II: Diagnostic Arthroscopy in the Beach-Chair Position.

Shoulder arthroscopy is a popular modality for the treatment of shoulder pathology. Since its advent in the 1970s, significant advancements have been made in both technology and technique. Shoulder arthroscopy is performed in either the beach-chair or lateral decubitus positions, and each position has its unique benefits and considerations.

Basics of Shoulder Arthroscopy Part III: Lateral Decubitus Patient Positioning and Operating Room Setup.

Shoulder arthroscopy is one of the most common orthopaedic procedures. Since its introduction in the 1970s, significant advances have been made in surgical techniques and instrumentation. Shoulder arthroscopy is often performed in either the beach-chair or lateral decubitus position, and each positioning technique has its own benefits.
