Primary repair of pectoralis major tendon with bony tunnels and anchor sutures in the proximal humerus creates a potential weakness and stress riser leading to increased risk of periprosthetic fracture and nerve damage at the site of weakness with subsequent injury, if not allowed to heal satisfactorily with adequate period of rest.

Background: As the use of robotics in total hip arthroplasty (THA) continues to gain popularity, differences in clinical outcomes when compared to manual techniques have remained unclear. This study aimed to compare postoperative complications between patients undergoing robotic-assisted techniques and manual THA for primary osteoarthritis at 90 days, 1 year, and 2 years.

Methods: Using an all-payer national database, we identified 405,048 patients who underwent either robotic-assisted or manual THA for primary osteoarthritis.

Cortical windows for implant and cement removal during revision total elbow arthroplasty.

JSES Int

November 2024

Division of Hand and Upper-Extremity Surgery, Department of Orthopaedic Surgery, Geisinger Commonwealth School of Medicine, Geisinger MSKI, Danville, PA, USA.

Background: Revision total elbow arthroplasty (rTEA) remains a technically challenging procedure with potential for substantial morbidity. Cases involving excessively long cement mantles, removal of well-fixed implants or infected revisions requiring complete cement removal introduce additional technical challenges. Our purpose was to describe the outcomes, results, and complications associated with the use of cortical windows in rTEA.

Background: Femoral condyle insufficiency fractures following total knee arthroplasty (FCIF-TKA) are rare but significant complications. These fractures, characterized by atraumatic bone insufficiency near the femoral component, present unique challenges in postoperative care, often necessitating femoral component revision.

Methods: This study retrospectively reviewed 835 primary total knee arthroplasties performed by a single surgeon, identifying six cases of FCIF-TKA.

Introduction Total hip arthroplasty (THA) is rarely indicated in the skeletally immature population. In these instances, there is concern for implant survival compared to the traditional older population. There has been a steady rise in the use of THA in the pediatric population due to improvements in surgical techniques.

Cost Effectiveness of Fixation Versus Total Hip Arthroplasty in Vancouver B2 Periprosthetic Femur Fractures: A Predictive Markov Analysis.

J Am Acad Orthop Surg

January 2025

From the Department of Orthopaedic Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA (Scott, Blackburn, Prasad, Lim, Lavoie-Gagne, Melnic, and Bedair), and the Department of Orthopaedic Surgery, Newton-Wellesley Hospital, Newton, MA (Scott, Blackburn, Prasad, Lim, Melnic, and Bedair).

Background: Although Vancouver B2 periprosthetic fractures (PPFs) have been historically managed with revision total hip arthroplasty (rTHA), open reduction and internal fixation (ORIF) has been proposed as an alternative option for reasons including lower cost and surgical time. The purpose of this study was to, therefore, create a Markov model to assess the cost effectiveness of ORIF versus rTHA for Vancouver B2 periprosthetic femur fractures and evaluate various inflection points for varying costs and outcome measures.

Methods: A Markov model was built using discrete and mutually exclusive health states of the hypothetical patient with Vancouver B2 PPF.
