However, surgeons are often concerned lag screw fixation will be inadequately strong. Lag screw fixation is a minimally invasive surgical procedure. No consensus has yet been reached regarding whether lag screw or bone plate fixation is the most favorable surgical method. Therefore, most hand surgeons do not consider K-wire fixation as the primary treatment for oblique metacarpal fractures. In K-wire fixation, the fixation strength is insufficient to withstand the torsion load at the fracture site this can lead to the rotational malunion of the fracture and eventually to a scissoring deformity. Currently, the following surgical methods are the most commonly used in clinical practice to treat oblique metacarpal shaft fractures: (1) lag screw fixation, (2) bone plate fixation, and (3) K-wire fixation. Few studies have specifically focused on the clinical treatment of oblique metacarpal bone fractures. However, for complex fractures with comminution or unstable metacarpal fractures, such as oblique fractures, spiral fractures, or those involving the shortening of the metacarpal bone due to overlapping fracture ends, surgical intervention is required to prevent subsequent complications. Most metacarpal bone fractures can be treated conservatively. Metacarpal fractures are not uncommon and account for approximately 40% of all hand fractures.
