Cases: Two patients presented to different surgeons complaining of persistent shoulder pain after reverse total shoulder arthroplasty. Workups for fracture, instability, and periprosthetic infection were negative. Advanced imaging, nerve conduction studies, and diagnostic injections localized symptoms to the suprascapular nerve. Revision arthroplasty with removal of the offending screws improved pain in both patients.
Conclusion: Suprascapular nerve irritation because of the malposition of baseplate screws in reverse total shoulder arthroplasty can be a source of postoperative pain. Removal of the offending screw without formal nerve exploration may result in symptomatic improvement.

Reverse shoulder arthroplasty in revision surgery-Indications and results.
PLoS One
January 2025
Division of Arthroscopic and special Joint Surgery / Sports Injuries, Department of Orthopedics, Trauma and Plastic Surgery, University of Leipzig, Leipzig, Germany.
Background: The number of reverse shoulder arthroplasty (RSA) procedures performed worldwide has increased over the last 10 years, with a corresponding increase in revision shoulder arthroplasty (SRSA). SRSA is often used for post-traumatic revision surgery in cases of infections and failure of anatomical prostheses. Data on outcomes with specific detail for each indication for the prosthetic solution as a secondary treatment are scarce, and inhomogeneous.

Objective: By comparing the hip arthroplasty parameters planned with the AIHIP three-dimensional simulation surgery system, this study analyzes the accuracy of the new femoral-side "shoulder-to-shoulder" artificial anatomical marker positioning method in femoral-side prosthesis implantation and the prevention of leg length discrepancy in hip arthroplasty.
Methods: A retrospective collection of 47 patients who underwent initial total hip arthroplasty at our hospital from August 2020 to December 2022 and met the inclusion and exclusion criteria was used as the study subjects. The average age was 67.

Department of trauma and orthopedics surgery. Mouwasat Hospital Dammam, 32263 Eastern Province Kingdom of Saudi Arabia.
Unlabelled: Introduction-Aim: Full-polyethylene glenosphere reverse shoulder arthroplasty (FP-RSA) known commonly as inverted-bearing concept utilizes a polyethylene glenosphere and metallic humeral liner. The aim was to assess mid-term outcomes of FP-RSA focusing on the incidence of scapular notching.
Methods: A retrospective analysis of 24 consecutive primary FP-RSA performed between 2017 and 2020 was conducted.
Is There an Association Between Postoperative Internal Rotation and Patient-reported Outcomes After Total Shoulder Arthroplasty?
Clin Orthop Relat Res
January 2025
Department of Orthopaedic Surgery, Washington University School of Medicine, St. Louis, MO, USA.
Background: Deficient internal rotation after shoulder arthroplasty can inhibit specific essential activities of daily living that require behind-the-back arm positioning. Although postoperative internal rotation deficits occur, their impact on outcomes of total shoulder arthroplasty (TSA) is not well established. Previous authors have validated the Single Assessment Numeric Evaluation (SANE) as a patient-reported assessment of acceptable outcomes of TSA.

- The primary goal of orthopaedic surgeons is to enhance the results of orthopaedic surgeries, particularly through innovative approaches.
- Nutritional interventions, which have not been a major focus before, can play a significant role in improving surgical outcomes.
- The article highlights how different nutritional strategies can positively influence recovery from fractures and elective surgeries, like ACL reconstruction and total shoulder replacements.
