High-Yield Summary Periprosthetic fractures require precise classification to guide treatment-implant stability and bone stock quality dictate operative strategy. Non-operative management is reserved for stable implants, minimal displacementand low-demand patients; surgical fixation or revision is indicated otherwise. Surgical approach and fixation method depend on fracture location, implant typeand bone quality; locking plates and revision stems are […]
High-Yield Summary Syndesmotic injuries complicate 10-20% of ankle fractures and require precise assessment to prevent chronic instability and post-traumatic arthritis. Key diagnostic indicators include the mechanism of injury (external rotation or hyperdorsiflexion), clinical tests (squeeze and external rotation stress tests)and advanced imaging (weight-bearing radiographs, CTor MRI). Classification systems guiding management focus on stability and displacement: […]
High-Yield Summary Patellar fractures and extensor mechanism disruptions require precise assessment of extensor continuity and articular congruity to guide management. Displaced fractures with >2 mm articular step-off or extensor lag mandate surgical fixation to restore knee mechanics and prevent post-traumatic arthritis. Tension band wiring remains the gold standard for transverse patellar fractures; comminuted or inferior […]
High-Yield Summary The Schatzker classification stratifies tibial plateau fractures into six types based on fracture morphology and mechanism, directly guiding surgical approach and fixation strategy. Lateral plateau fractures (Types I-III) are most common; medial (Type IV) and bicondylar (Types V-VI) fractures often require more complex fixation and carry higher risk of soft tissue injury. Accurate […]
High-Yield Summary Distal femoral fractures require stable fixation that restores articular congruity and axial alignment while allowing early mobilization; fixed-angle devices are the gold standard for most displaced fractures. Understanding the distal femur’s complex anatomy and load transmission is critical for implant positioning and achieving biomechanical stability. Classification systems such as the AO/OTA guide surgical […]
High-Yield Summary Complex tibial pilon fractures involve articular comminution and metaphyseal-diaphyseal dissociation, requiring precise restoration of joint congruity and limb alignment to prevent post-traumatic arthritis. Circular external fixation offers biomechanical advantages including multiplanar stability, load sharingand minimal soft tissue disruption, critical in high-energy, soft tissue-compromised injuries. Staged management with initial spanning external fixation followed by […]
High-Yield Summary Subtrochanteric femur fractures occur in the proximal femur region extending 5 cm distal to the lesser trochanter, characterized by high biomechanical stress and deforming muscle forces complicating reduction. Intramedullary nailing is the gold standard for fixation, offering biomechanical advantages and improved outcomes compared to extramedullary devices. Achieving anatomic or near-anatomic reduction is critical; […]
High-Yield Summary Intertrochanteric fractures require stable fixation to restore early mobility and reduce morbidity; implant choice hinges on fracture stability and patient factors. Sliding hip screws (SHS) remain effective for stable, non-comminuted fractures with intact lateral walls. Cephalomedullary nails (CMN) offer biomechanical advantages in unstable patterns, reverse obliquityor lateral wall compromise, reducing varus collapse and […]
High-Yield Summary The Pipkin classification stratifies femoral head fractures by location and associated injuries, directly guiding surgical approach and fixation strategy. Type I and II fractures involve the femoral head below or above the fovea capitis, respectively, with Type II often requiring more aggressive fixation due to weight-bearing surface involvement. Type III combines femoral head […]
High-Yield Summary Volar locking plates provide stable fixation for distal radius fractures, especially in osteoporotic bone and comminuted patterns, enabling early mobilization and improved functional outcomes. Key surgical goals include restoration of volar tilt, radial height, and radial inclination to prevent long-term wrist dysfunction. Indications for operative fixation include unstable fractures with displacement, intra-articular involvement, […]
