High-Yield Summary The NOMS framework integrates Neurologic, Oncologic, Mechanicaland Systemic factors to guide individualized management of metastatic spine disease, optimizing outcomes through multidisciplinary decision-making. Neurologic assessment focuses on the degree of epidural spinal cord compression and neurologic deficits, directing the need for decompression. Oncologic evaluation considers tumor radiosensitivity and systemic disease burden, influencing the choice […]
High-Yield Summary Radial nerve palsy results in wrist, fingerand thumb extension loss, critically impairing hand function; timely diagnosis and intervention dictate outcomes. Nerve repair is preferred within 6 months of injury when direct repair or grafting is feasible; delayed presentations often require tendon transfers. Tendon transfers restore function reliably in chronic palsy or failed nerve […]
High-Yield Summary Vascular injury during total hip arthroplasty (THA) is rare (<0.2%) but carries high morbidity, including limb ischemia and potential amputation. The external iliac and common femoral arteries are most commonly injured due to their proximity to the acetabulum and femoral canal. Early recognition via intraoperative bleeding, loss of distal pulsesor postoperative limb ischemia […]
High-Yield Summary Diastrophic dysplasia (DTD) is a rare autosomal recessive skeletal dysplasia characterized by limb shortening, joint contracturesand distinctive “hitchhiker” thumbs, requiring multidisciplinary management with a focus on staged orthopedic interventions. Surgical indications hinge on functional impairment, progressive deformityand respiratory compromise; timing balances growth potential against deformity severity. Corrective osteotomies, soft tissue releasesand spinal stabilization […]
High-Yield Summary First metatarsophalangeal (MTP) joint fusion is the definitive surgical treatment for end-stage hallux rigidus, severe arthritisand failed prior joint-preserving procedures. Optimal fusion position is 10-15 degrees dorsiflexion and 10 degrees valgus to restore gait mechanics and shoe wear compatibility. Rigid fixation with compression plating or crossed screws yields the highest union rates (>90%) […]
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 The AJCC staging system for soft tissue sarcomas (STS) integrates tumor size, depth, gradeand nodal/metastatic status to guide prognosis and treatment planning. Tumor grade, based on histologic differentiation, mitotic rateand necrosis, is a critical determinant of stage and survival. Depth (superficial vs. deep) and size thresholds (?5 cm, >5 cm to ?10 cm, […]
High-Yield Summary Quadriceps tendon ruptures predominantly occur in middle-aged to elderly patients with systemic risk factors; prompt diagnosis and surgical repair are critical to restore extensor mechanism function. Transosseous tunnel repair (TTR) and suture anchor repair (SAR) are the two primary surgical techniques; both provide biomechanically sound fixation but differ in surgical complexity, implant costand […]
High-Yield Summary Seddon Classification defines nerve injury into three types-neurapraxia, axonotmesisand neurotmesis-based on severity and prognosis, guiding initial management and timing of intervention. Sunderland Classification expands Seddon’s framework into five degrees, providing granular detail on the extent of nerve fiber and connective tissue disruption, critical for surgical decision-making. Accurate differentiation between injury types hinges on […]
High-Yield Summary Total elbow arthroplasty (TEA) is primarily indicated for complex distal humerus fractures in elderly patients, inflammatory arthritis with joint destructionand select post-traumatic arthritis cases with severe functional limitation. Implant selection (linked vs. unlinked) and surgical approach must be tailored to bone quality, soft tissue integrityand patient activity level to optimize longevity and function. […]
