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, […]
High-Yield Summary Reaming enlarges the medullary canal to accommodate a larger-diameter nail, enhancing mechanical stability and load sharing. Controlled reaming preserves endosteal blood supply while stimulating periosteal blood flow and osteogenic activity. Over-reaming or aggressive technique risks thermal necrosis, fat embolism, and delayed healing. Reamed nails demonstrate superior union rates and lower implant failure compared […]
High-Yield Summary Lisfranc injuries involve disruption of the tarsometatarsal (TMT) joint complex, with subtle presentations requiring high clinical suspicion and weight-bearing radiographs for diagnosis. The stability of the Lisfranc ligament complex dictates management; displacement >2 mm or joint incongruity mandates operative fixation. Open reduction and internal fixation (ORIF) remains the gold standard for unstable injuries, […]
High-Yield Summary The Lauge-Hansen classification defines ankle fractures by the mechanism of injury, integrating foot position and force direction, guiding surgical approach and fixation strategy. The Danis-Weber classification categorizes fractures by fibular fracture level relative to the syndesmosis, directly influencing stability assessment and operative indication. Accurate diagnosis requires combined clinical, radiographic, and stress imaging to […]
High-Yield Summary Displaced intra-articular calcaneal fractures require precise anatomical reduction to restore subtalar joint congruity and prevent post-traumatic arthritis. The Sanders classification, based on CT imaging, remains the cornerstone for guiding operative versus non-operative management. Surgical approach selection balances exposure for reduction with soft tissue preservation; extensile lateral approach offers visualization but carries higher wound […]
