Rare multicentric calcifying aponeurotic fibroma presented as presumed lymphatic malformation with nerve compression and distal radioulnar dysplasia.
Pronator quadratus repair integrity after anterior plating of distal radial fractures correlates with improved grip strength at 1 year but not with motion or disability scores.
Outcomes of open dorsal proximal interphalangeal joint dislocations.
Open dorsal proximal interphalangeal dislocations without routine palmar plate reinsertion achieved low residual instability despite frequent stiffness.
Progressive Giant Orf Disease With Recurring.
Giant orf disease with extensive hand involvement in immunocompromised patients requires careful management to prevent spread during surgical intervention.
Standardized volar silicone PIP arthroplasty with bilateral collateral release and non-repair strategy provides reproducible exposure and soft-tissue rebalancing.
Surface replacement arthroplasty for PIP osteoarthritis showed 86.5% healing but 26% complication rate, with two distinct temporal patterns: early flexion contracture and late extension contracture.
Surgery reduced scaphoid nonunion by half but showed only modest functional improvement and increased complications sevenfold; cast immobilization remains reasonable for undisplaced fractures.
Second metatarsal head demonstrates anatomical equivalence to capitate articular surface in width and radius of curvature, supporting its use as a donor for lunocapitate reconstruction.
Dynamic analysis of nerves around the elbow using MRI-derived 3-D modeling.
MRI-derived 3D nerve modeling in volunteers showed the posterior interosseous nerve moves farther from the lateral epicondyle with elbow flexion, informing safer placement of arthroscopic portals.
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.
4DCT-derived hysteresis is greater in scapholunate ligament-injured wrists than healthy wrists, potentially serving as a dynamic imaging marker for carpal instability.
Proximal and middle phalangeal intramedullary canal diameters vary by digit and gender; 2.0-3.0 mm headless screws best match most phalangeal canals for fracture fixation.
Radiographic alignment after 360-degree scapholunate ligament reconstruction did not predict patient-reported pain or function at minimum 3-year follow-up.
Neither the lateral ulnohumeral joint space nor proximal sigmoid notch are sufficiently reliable radiographic landmarks for assessing radial head prosthetic overlengthening intraoperatively.
Transtendinous corticosteroid injection at proximal phalanx reliably delivers medication intra-sheath with 70% achieving total symptom relief within 6 weeks.
Finger function depends on balanced intrinsic and extrinsic mechanisms; understanding these dynamics is essential for diagnosing imbalance and planning reconstructive strategies.
Evidence suggests preoperative cannabis use does not significantly affect postoperative opioid consumption after orthopaedic surgery, though pain outcomes remain mixed.
Conflicts of interest pervasive in hand surgery; up to 81% authors fail accurate disclosure, requiring transparency, institutional registries, and standardized journal policies.
Outcome Measures after Peripheral Nerve Injury: Past, Present and Future.
Peripheral nerve injury outcome measurement lacks standardization; advances in wearable devices and motion-tracking offer objective real-time monitoring beyond traditional clinical assessments.
Management of the Spastic Elbow Deformity in Adult Patients With Upper Motor Neuron Syndrome.
Spastic elbow deformity management requires individualized surgical planning using techniques like neurectomy, tendon lengthening, and soft tissue release based on volitional control.
Management of Elbow Terrible Triad Injuries: A Comprehensive Review and Update.
Terrible triad elbow injuries require systematic surgical repair of lateral ligaments, radial head, and coronoid with early mobilization to prevent stiffness.
Growth Factors to Enhance Nerve Regeneration: Approaching Clinical Translation.
Growth factors promote nerve regeneration but require engineered drug delivery systems to overcome short half-life barriers for clinical translation and sustained therapeutic effect.
Compressive Neuropathies of the Upper Extremity: Anatomy for the Peripheral Nerve Surgeon.
This article outlines anatomic regions and approaches for peripheral nerve compression in the upper extremity to guide surgical decompression.
Small Joint Denervation of the Hand and Thumb Base: History, Anatomy, Technique, and Outcomes.
Denervation is an emerging alternative to arthroplasty for painful small joint arthritis, offering faster surgery and recovery times with improving reported outcomes.
Superficial Circumflex Iliac Artery Perforator Flap Reconstruction of the Upper Extremity.
Superficial circumflex iliac artery perforator flap provides thin, pliable tissue for hand and upper extremity reconstruction with reduced secondary procedures.
