High-Yield Explanation
Clavicle fracture treatment includes immobilization in sling or figure of eight bandages. Option `b' requires specific mention here because different books have a different opinion regarding the most common site of the fracture. "The most common site is at the junction of the middle and outermost thirds" -- Adams's "The junction of the middle and outer third of the clavicle is the commonest site". -- Maheshwari "Fractures of midshaft account for 69-12 percent of all clavicle fractures". -- Apley's "The mid-clavicle (middle third) therefore is the most common site of fracture". -- Rockwood "Middle third of clavicle is the most common site of fracture". Atlas of musculoskeletal imaging. "Eighty-five percent of the fracture clavicle occurs at the junction of the middle and outer third". Ebnezar. "Although a fracture can occur anywhere along the clavicle, the most common site (80% of cases) is reported to be between medial 2/3rd and lateral 1/3rd of the bone". -- "The middle clavicle is the most common site of the fracture, representing 75-80% of all clavicle fractures". Essentials of skeletal radiology. "Eighty percent of the fractured clavicle occurs at the junction of middle and outer third" -- Essential of orthopaedics Though some textbooks have mentioned the middle third as the most common site for clavicle fracture, most textbooks have mentioned the junction of medial 2/3rd and lateral 1/3rd as the commonest site of the fracture. According to me the most common site of clavicle fracture is at the junction of medial 2/3rd and lateral 1/3rd.
