Reproducing Valgus Angle in Uncemented Humeral Hemiarthroplasty.
Uncemented humeral hemiarthroplasty can reproduce native valgus alignment within 4 degrees radiographically, supporting its use for elbow arthritis reconstruction.
Conjoint tendon augmentation demonstrated clinical noninferiority to Latarjet procedure for recurrent shoulder dislocation while avoiding bone-block complications.
The Sarcophagus technique combining intramedullary nailing with circumferential cortical strut allograft achieves 87.5% union rate in humeral shaft nonunion with favorable functional recovery and minimal complications.
Proximal neuropathy occurs in 40% of massive rotator cuff tears and strongly correlates with pseudoparalysis; EMG should guide selective preoperative evaluation of large tears.
Lateral epicondylar fractures in the pediatric population: Presentation, management, and outcomes.
Pediatric lateral epicondyle fractures are rare but frequently missed sports injuries; nondisplaced cases heal well with immobilization while displaced fractures require careful assessment for concomitant injuries.
Arthroscopic partial repair for large-to-massive rotator cuff tears achieved significant pain and functional improvement despite 30% structural retear rate at 2-year follow-up, with worse outcomes in patients with recurrent tears.
Is surgery always warranted for high-grade acromioclavicular dislocations?
Surgical fixation of high-grade AC dislocations improved radiographic alignment but not functional outcomes compared to selective conservative management; clinical criteria should guide treatment decisions.
Functional electromyostimulation improvements persist six months post-program in reverse shoulder arthroplasty patients without deterioration after device discontinuation, supporting sustained benefit.
Kyphotic scapular posture increases posterior deltoid demand and acromial spine strain by 150%, reducing anterior deltoid mechanical advantage during shoulder motion.
Full-duty return to work exceeded 90% after meniscectomy, meniscal repair, and ACL reconstruction but ranged 74-77% after rotator cuff repair, hip arthroscopy, and biceps tenodesis, with workers' compensation associated with prolonged timelines.
Scapular rotation significantly influences effective glenoid component inclination in reverse shoulder arthroplasty despite targeting neutral positioning, suggesting preoperative assessment should guide component placement to optimize outcomes.
Suprascapular nerve decompression significantly improves pain and strength outcomes in young active military patients presenting with compression at the suprascapular notch.
Cross-cultural adaptation and validation of the Arabic version of the Pennsylvania Shoulder Score.
The Arabic Pennsylvania Shoulder Score demonstrated excellent reliability, validity, and cultural appropriateness for measuring shoulder function in Arab-speaking populations.
Custom 3D-printed glenoid implants in reverse shoulder arthroplasty optimize bone-implant stability through central peg fixation, porous surfaces, and computed tomography-based planning for severe glenoid bone loss.
Long Head of the Biceps Tendon Pathology: From Etiology to Management.
Long head biceps pathology involves complex interplay with superior labrum and rotator cuff; comprehensive evaluation and individualized treatment approaches improve outcomes.
Posterior Shoulder Instability in Athletes.
Posterior shoulder instability in athletes presents with pain and instability, diagnosed clinically with imaging, managed nonoperatively initially, with shoulder arthroscopy and posterior labral repair for surgical candidates.
Artificial intelligence in shoulder and elbow surgery: overview of current and future applications.
Artificial intelligence in shoulder and elbow surgery shows utility for imaging diagnosis, outcome prediction, and automated segmentation, with future integration in robotic surgery offering significant potential clinical impact.
MCID reporting is rising in shoulder/knee sports medicine literature but is frequently applied and reported incorrectly, undermining accurate interpretation of clinical significance.
Technical Tips for Reduction and Stable Fixation of Proximal Humerus Fractures.
Technical innovations including fibular strut allograft, calcar screw placement, and systematic reduction improve outcomes in proximal humerus fracture fixation.
Revision Arthroplasty in the Challenging Elbow.
Revision total elbow arthroplasty faces high complication rates; successful outcomes require careful soft tissue handling, bone preservation, and infection management.
FECTS scale and RCR-IGA scale reliably assess repaired rotator cuff ultrasound appearance, with FECTS better for inexperienced raters and RCR-IGA more time-efficient.
Decision-making in the treatment of radial head fractures: Delphi methodology.
Expert consensus identified fracture displacement ≥2mm, motion block after aspiration, and head involvement ≥30% as key factors favoring operative treatment for radial head fractures.
Posterior Humeral Avulsion of the Glenohumeral Ligament: A Critical Analysis Review.
Posterior humeral avulsion of the glenohumeral ligament causes posterior instability predominantly in athletes with flexion-adduction-internal rotation injury; diagnosis often requires arthroscopy with arthroscopic fixation as primary treatment.
