![]() for this reason, pure transmetatarsaltarsal dislocations rarely occur, & rather involve frxs thru or around the second metatarsal baseįractures associated with neuropathic arthropathy in adults who have juvenile-onset diabetes. no significant dislocation of the metatarsals or cuneiforms can occur unless this bone is disrupted this mortise configuration effectively locks the entire tarsometarsal complex, preventing medial or lateral translation volar aspect of the second metatarsal is heavily reenforced by ligaments as compared to the dorsal aspect of the metatarsal base ref: Fractures of the distal shaft of the fifth metatarsal. in cases where the long oblique frx spike lies dorsally are particullary ammenable to ORIF w/ antigluide plate often these fractrues will have a long oblique fracture pattern which makes them ammenable to fixation, w/either 2.7 mm lag screws or a 2.7 mm antigluide plate displaced frxs (3-5 mm) may require ORIF mildly displaced frx: heal w/ 6 to 8 weeks w/ short leg cast radiographs: take care to order AP, lateral and oblique views since often one view shows significantly more displacement than the others frx is frequently displaced, and occassionally midly comminuted perineal weakness and simple fatigue may be contributory factors ![]() mechanism: inversion injury resulting from mis-steps & falls off the dem pointe position spiral frx of 5th metatarsal neck which is common in ballet dancers ![]() this is insertion point of peroneus tertius transverse fracture thru base of 5th metatarsal, about 1-2 cm from tip Avulsion frx of base of 5th metatarsal from pull of peroneus brevis Stress Fractures of the Forefoot and Midfoot ![]()
