A. Fracture distal end humerus, B. Extra-aicular fracture distal end radius, C. Intra-aicular fracture distal end radius, D. Intra-aicular fracture distal end radius with carpal bone subluxation
D: Intra-aicular fracture distal end radius with carpal bone subluxation
Answer: D: Intra-aicular fracture distal end radius with carpal bone subluxation 
Explanation: Baon&;s fracture is an intra aicular fracture of distal radius. Here fracture extends from aicular surface of the radius to either its anterior or posterior coices. The small distal fragments get displaced and carries with it the carpals.(carpal bone subluxation) 2 types of volar Baons fracture and dorsal Baons fracture. Treatment: closed manipulation and plaster cast. when closed reduction fails, internal fixation with plate may be required. Ref: Essential Ohopaedics, Maheswari & Mhaskar, 9th ed, Page no: 114
