    Rotator cuff-sparing deltopectoral approach for humeral intramedullary nailing achieves good functional outcomes with low iatrogenic shoulder pain and no revisions needed.

    Journal of Shoulder and Elbow Surgery · Jul 15 2026 · PubMed

    Arthroscopic pectoralis minor release improves pain, function, and forward elevation in patients with pectoralis minor syndrome and neurogenic thoracic outlet syndrome with low complication rates.

    Journal of Shoulder and Elbow Surgery · Jul 15 2026 · PubMed

    Rifampin combined with vancomycin or other antibiotics provides optimal PMMA elution against C. acnes and CNS species for 60 days, supporting its use in shoulder prosthetic joint infection.

  5. Triceps-sparing approach results in better elbow function compared to triceps-detaching approach in total elbow arthroplasty: A multicenter prospective cohort study.

    Journal of Shoulder and Elbow Surgery · Jul 15 2026 · PubMed

    In a multicenter cohort study, triceps-sparing total elbow arthroplasty produced significantly less fixed flexion deformity than triceps-detaching approaches, though complication rates were similarly high between groups.

  6. Multiplanar CT-based characterization of offset and positional change in reverse shoulder arthroplasty and validation of radiographic metrics.

    Journal of Shoulder and Elbow Surgery · Jul 15 2026 · PubMed

    Current radiographic metrics insufficiently capture reverse shoulder arthroplasty implant position and changes; CT multiplanar reconstruction provides more accurate assessment.

  7. Computerized Branching Logic Systems Significantly Improve the Accuracy of ASES Scores for Patients with Bilateral Shoulder Pain Undergoing Shoulder Arthroplasty.

    Journal of Shoulder and Elbow Surgery · Jul 14 2026 · PubMed

    Branching logic systems significantly improved accuracy of ASES scores for bilateral shoulder pain patients undergoing shoulder arthroplasty by better capturing contralateral shoulder status.

  8. Evaluation of Radiograph Parameters Used to Assess Prosthetic Overlengthening in Radial Head Arthroplasty.

    Journal of Shoulder and Elbow Surgery · Jul 04 2026 · PubMed

    Neither the lateral ulnohumeral joint space nor proximal sigmoid notch are sufficiently reliable radiographic landmarks for assessing radial head prosthetic overlengthening intraoperatively.

  9. The Humeral Bone Loss (HUMBL) Classification Identifies Patterns of Humeral Bone Loss Associated with Various Revision, Instability, and Humeral Loosening Rates in Primary and Revision Shoulder Arthroplasty.

    Journal of Shoulder and Elbow Surgery · Jul 03 2026 · PubMed

    HUMBL classification identifies humeral bone loss patterns associated with significantly increased revision, instability, and loosening rates, with ectatic bone loss showing the highest complication risk.

  10. Yoda1 Promotes Tendon-to-Bone Healing by Regulating M1/M2 Macrophage Polarization in a Rat Model of Rotator Cuff Repair.

    American Journal of Sports Medicine · Jun 29 2026 · PubMed

    Yoda1 treatment promotes rotator cuff healing by increasing M2 macrophage infiltration and improving biomechanical properties at the tendon-bone interface.

  11. "Am I too old for a shoulder replacement?" The association between age and comorbidities on the outcomes following Reverse Shoulder Arthroplasty.

    Journal of Shoulder and Elbow Surgery · Jun 24 2026 · PubMed

    Reverse shoulder arthroplasty in patients ≥80 years has low revision rates (3.4% at 9 years) but medical complications and mortality increase with advancing age.

  12. Thirty-Six Months of Experience and 30° of Hip Internal Rotation as Critical Thresholds for Capitellar Osteochondritis Dissecans in Youth Baseball Players.

    Journal of Shoulder and Elbow Surgery · Jun 15 2026 · PubMed

    Youth baseball players with ≥36 months competitive experience and <30° nondominant hip internal rotation are at significantly higher risk for capitellar osteochondritis dissecans.

  13. Seasonal timing of surgery does not affect clinical outcomes in reverse total shoulder arthroplasty.

    Shoulder & Elbow · Aug 04 2025 · PubMed

    Seasonal timing of reverse total shoulder arthroplasty does not significantly affect 2-year clinical outcomes, complications, or range of motion.

Recent reviews

  1. Optimizing Outcomes in Total Elbow Arthroplasty.

    Journal of the American Academy of Orthopaedic Surgeons · Feb 01 2026 · PubMed

    Total elbow arthroplasty complication rates exceed other joint replacements; success requires careful patient selection, proper surgical technique, and realistic patient counseling on mechanical failure risks.

  2. Advancement in Care Through Applied Translational and Clinical Research in Anterior Shoulder Instability: Military Contribution Over 25 Years: Kappa Delta Award.

    Journal of the American Academy of Orthopaedic Surgeons · Dec 01 2025 · PubMed

    Military orthopaedic research over 25 years advanced anterior shoulder instability management through epidemiology, biomechanics, imaging validation, and novel glenoid reconstruction techniques like distal tibia allograft.

  3. Kappa Delta Elizabeth Winston Lanier Award: Understanding the Role of Fibroadipoprogenitor Cells in Rotator Cuff Disease.

    Journal of the American Academy of Orthopaedic Surgeons · Dec 01 2025 · PubMed

    Fibroadipoprogenitor cells drive fatty infiltration in rotator cuff disease; understanding their role informs potential stem cell-based treatments to improve repair outcomes.

  4. Allograft Prosthetic Composites in Complex Primary and Revision Shoulder and Elbow Arthroplasty.

    Journal of the American Academy of Orthopaedic Surgeons · Oct 15 2025 · PubMed

    Allograft prosthetic composites restore bone stock in complex primary and revision shoulder/elbow arthroplasty but risk graft resorption and nonunion.

    Arthroscopy · Feb 2025 · PubMed

    An international Delphi consensus of shoulder experts agreed on return-to-play and revision criteria for posterior shoulder instability, but found no consensus on optimal glenoid bone graft fixation or osteotomy indications.

  6. Ulnar Collateral Ligament Injuries in Overhead Athletes: Diagnosis, Management, and Clinical Outcomes.

    Journal of the American Academy of Orthopaedic Surgeons · Jan 01 2025 · PubMed

  7. Optimizing Outpatient Shoulder Surgery: A Review of Anesthetic Options.

    Journal of the American Academy of Orthopaedic Surgeons · Jan 01 2025 · PubMed

    Regional anesthetic options for outpatient shoulder surgery are critical for reducing length of stay; literature supports multimodal approaches over general anesthesia alone.

    Journal of the American Academy of Orthopaedic Surgeons · Oct 01 2024 · PubMed

    Terrible triad elbow injuries require systematic surgical repair of lateral ligaments, radial head, and coronoid with early mobilization to prevent stiffness.
