We review everything you need to understand about Orthopedic MCQS online Anatomy 017. Neurogenic claudication, characterized by a "shopping cart" sign, often stems from spinal stenosis due to a symptomatic synovial cyst, a gelatinous lesion typically requiring surgical excision. Separately, a wellfixed uncemented stem describes an orthopedic implant designed for secure, cement-free integration into bone, commonly used in joint replacement surgery.
