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.

Return to Sport and Patient-Reported Outcomes After Subpectoral Biceps Tenodesis for SLAP Tear in Collegiate Gymnasts.

Background: The biceps superior labral complex is a known source of shoulder dysfunction in young, high-level athletes. Superior labral anterior-posterior (SLAP) repairs are often unsatisfactory for treating biceps-labral pathology in this demographic group, with high failure rates and poor return to sport (RTS). Minimal data have been published to demonstrate patient-reported outcomes (PROs) and RTS in gymnasts after treatment of SLAP pathologies.

Intimate Partner Violence in the Orthopaedic Patient Population: What Surgeons Need to Know.

»: Intimate partner violence (IPV) is under-reported and pervasive in the orthopaedic surgical setting.

»: Screening programs that could increase reporting and assist in treatment and prevention are commonly underutilized.

»: There is little formalized education during orthopaedic surgery training for IPV.

Maintains Renal Progenitors and Regulates Podocyte Development by Promoting via the Antagonism of .

Knowledge about the genetic pathways that control nephron development is essential for better understanding the basis of congenital malformations of the kidney. The transcription factors Osr1 and Hand2 are known to exert antagonistic influences to balance kidney specification. Here, we performed a forward genetic screen to identify nephrogenesis regulators, where whole genome sequencing identified an lesion in the novel () mutant.

Superior Capsular Reconstruction: A Salvage Option for Massive Irreparable Rotator Cuff Tears with Pseudoparalysis or Subscapularis Insufficiency.

Purpose: We sought to examine superior capsular reconstruction (SCR) outcomes after minimum 2-year follow-up and determine risk factors that were predictive of outcomes.

Methods: Forty consecutive patients (mean age 57.3 years, 87.

The utility and cost of atypical cultures in revision shoulder arthroplasty.

Background: At the time of revision shoulder arthroplasty, it is common practice to take cultures to evaluate for prosthetic joint infection even when an alternative cause of failure has been identified. Although isolation of fungal or acid-fast organisms is rare, it remains common practice to send all specimens for aerobic, anaerobic, and atypical (fungal and acid-fast) cultures. We hypothesize that the rate of positive atypical cultures at the time of revision shoulder arthroplasty is very low and routine use imposes a considerable financial burden on the health care system.
