In an 80-patient randomized trial, surgeon-performed shoulder field anesthesia was noninferior to interscalene block for 48-hour pain after arthroscopic shoulder surgery, with shorter stay and no block-related complications, though early pain relief was better with ISB.
Technical note describing an inlay dynamic anterior shoulder stabilization using the long head biceps tendon and all-suture anchors, combined with Bankart repair, for anterior instability with less than 20% glenoid bone loss.
In 8,601 New Zealand registry rTSAs, polyethylene glenospheres had 43% lower adjusted revision risk than metal glenospheres, with similar Oxford Shoulder Scores, suggesting an inverted-bearing advantage in long-term survivorship.
This systematic review of 14 mostly high-bias observational studies found conflicting, insufficient evidence that statins, ARBs, or ACE inhibitors prevent arthrofibrosis after knee, hip, or shoulder surgery.
In a matched national database study, surgical stabilization for recurrent anterior shoulder dislocation carried far higher early re-dislocation and instability rates than for primary dislocation; elevated BMI and seizure disorders were also risk factors.
The preoperative SHORD score, built from 29,382 TSA patients in NSQIP, predicts non-home discharge well (AUROC 0.816), outperforming frailty and ASA measures, and could aid early discharge planning pending external validation.
On bilateral CT of 304 healthy patients, scapular morphology was largely symmetrical, suggesting extreme posterior acromial shapes are bilateral constitutional traits rather than asymmetric findings.
In 119 patients, a machine-learning model found wrist-level CMAP amplitude (≥6.6 mV) and preoperative clinical severity (McGowan grade ≤IIA) were the key predictors of good outcome after anterior subcutaneous ulnar nerve transposition for cubital tunnel syndrome.
ChatGPT simplification cut pediatric orthopaedic discharge documents from about an 8.9 to a 5.0 grade reading level, but 14 of 15 documents contained flagged errors including safety-critical ones, so clinician review is essential.
In 53 patients with irreparable posterosuperior rotator cuff tears, arthroscopic-assisted lower trapezius transfer improved function at 2 years regardless of preoperative external rotation lag sign, with most recovery within 3 months.
In 30 patients, a custom 3D-printed arthrodesis prosthesis after proximal humerus tumor resection gave 100% fusion and good function (MSTS 84%), but total deltoidectomy raised soft-tissue failure risk.
In 30 terrible triad elbow injuries fixed without radial head prostheses, 77% had good-to-excellent function, but instability (40%), arthritis (50%), and K-wire olecranon fractures were notable; low follow-up limits conclusions.
Describes an all-arthroscopic rotator cuff muscle advancement for massive posterosuperior tears, adding scapular triangular view and complete Hakusen-triangular area release to improve cuff excursion and enable low-tension repair; supported by cadaveric comparison.
In a large matched cohort, total elbow arthroplasty patients with both anxiety and depression had roughly double the risk of wound complications, readmission, loosening, and dislocation, warranting closer perioperative counseling and monitoring.
In 17 patients with paralytic shoulder, glenohumeral fusion with a subacromial locking plate achieved 100% union at ~4.8 years with few complications and no plate removals for intolerance; fusion angle correlated with motion.
In a matched cohort of 40 shoulders, early ultrasound measures of subscapularis sliding and external rotation predicted stiffness one year after arthroscopic rotator cuff repair, with reliable measurements.
Narrative review of proximal humerus fracture management: non-operative care suits many elderly patients, locked plating has high complication rates without proven superiority, and reverse arthroplasty is increasingly favored, though evidence remains limited.
Review concludes radial head prosthesis diameter should match the reconstructed native head (or CT capitellar width) and height should align with the lesser sigmoid notch, since mismatch causes pain, stiffness, and arthritis.
An international Delphi panel of 98 trauma surgeons agreed on 43 scored assessment parameters for judging technical competence in tension band wiring of transverse olecranon fractures, with anatomical reduction rated most important.
Monteggia Fracture Dislocation.
Review of Monteggia fracture-dislocations (proximal ulna fracture with radial head dislocation) covering anatomy, evaluation, classification, surgical management, and recent advances to guide operative planning.
Complex Elbow Fracture-Dislocations: An Algorithmic Approach to Treatment.
Proposes an algorithmic approach to diagnosing and treating complex elbow fracture-dislocations, emphasizing reconstruction of bony and ligamentous stabilizers, versatile fixation, and structured rehabilitation to restore a stable elbow.
Recurrent Instability after the Latarjet Procedure.
Review of causes and management of failure after the Latarjet procedure, which has a 15 to 30% complication rate, covering glenoid bone grafting options (including distal tibial allograft) and soft-tissue procedures.
High degree of consensus on diagnosis and management of rotator cuff tears: a Delphi approach.
A Delphi panel of 41 Italian shoulder experts reached consensus on 51 of 56 statements, endorsing preoperative MRI and holding that age and pseudoparalysis do not contraindicate rotator cuff repair.
Modern Applications of Machine Learning in Shoulder Arthroplasty: A Review.
Review of machine learning in shoulder arthroplasty, covering prediction of outcomes like range of motion and complications, implant identification for revision planning, and future applications.
Open fractures of the upper limb - do the BOAST guidelines need an update?
This scoping review finds that open upper limb fractures have lower infection rates than lower limb injuries, suggesting BOAST timing could be relaxed in selected cases, though early antibiotics and debridement within 24 hours remain key.
Discussions About Obstetric Brachial Plexus Injuries.
Expert discussion of six unsettled issues in obstetric brachial plexus injury, including causation, Narakas grading, primary nerve surgery in incomplete injuries, shoulder and elbow contractures, and adult surgery.
