Fig. 1From: Effect of oblique headless compression screw fixation for metacarpal shaft fracture: a biomechanical in vitro studyPorcine fifth metacarpals and four fixation types for metacarpal shaft fracture. a Straight locked plate with four locked bicortical screws (LP group). b Straight regular plate with four bicortical screws (RP group). c Cross-pin fixation of two K wires (K group). d Headless compression screw (HC group). Radiographs of the four fixation types are also shown in this figure (upper row: anterior–posterior view; bottom row: lateral view)Back to article page
