Enhanced recovery protocols (ERAS) enable same-day/next-day discharge in selected patients. Selection: ASA I–II, motivated, good support, no major comorbidities or bleeding risks....
Arthroplasty | 👁 3 | 2 weeks agoT- or Y-shaped intra-articular fractures of the distal humerus. Most common in young adults (high energy) and elderly osteoporotic (low energy). Require anatomic articular reductio...
Trauma | 👁 6 | 2 weeks agoSimultaneous fracture of radius and ulna compromises pronation-supination. Adults: ORIF with plating is gold standard; children: closed reduction & casting. Principle: restore leng...
Trauma | 👁 10 | 2 weeks agoComputer-assisted surgery (CAS) improves component alignment in TKA/THA. Techniques: imageless and CT-based navigation. Benefits: improved mechanical axis alignment, reduced outlie...
Arthroplasty | 👁 4 | 2 weeks agoRobotics assists bone preparation and implant positioning (mostly semi-active systems). Potential: improved accuracy, reproducibility, individualized alignment strategies. Limitati...
Arthroplasty | 👁 3 | 2 weeks agoPSI uses preop MRI/CT to fabricate custom cutting jigs. Goal: improve accuracy, reduce OR time/inventory; evidence shows marginal accuracy gains without clear functional benefit. L...
Arthroplasty | 👁 3 | 2 weeks agoTHA: cementless acetabular components standard; femoral fixation cemented (elderly) vs cementless (younger). TKA: tibial components commonly cemented; cementless options increasing...
Arthroplasty | 👁 6 | 2 weeks agoUKA: isolated compartment OA, intact ACL/collaterals, correctible deformity; faster recovery, more natural kinematics. TKA: multicompartment disease, inflammatory arthritis, signif...
Arthroplasty | 👁 5 | 2 weeks agoControversial: to resurface or not during TKA. Resurfacing: reduces anterior knee pain, avoids secondary resurfacing procedures. Non-resurfacing: avoids patellar complications (fra...
Arthroplasty | 👁 5 | 2 weeks agoCommon indications: aseptic loosening, PJI, instability, stiffness, polyethylene wear, periprosthetic fracture, malalignment. Workup: exclude infection (ESR/CRP ± aspiration); quan...
Arthroplasty | 👁 6 | 2 weeks agoPrimary driver of late osteolysis and aseptic loosening in TKA. Wear modes: adhesive/abrasive; delamination & pitting with high contact stress/oxidation in older PE. Risk factors:...
Arthroplasty | 👁 3 | 2 weeks agoPeriprosthetic osteolysis = bone loss from wear particle-induced inflammation. Detected on radiographs as radiolucencies, cystic defects; CT useful for mapping, MRI (MARS) for soft...
