Introduction: Metacarpal and phalangeal fractures are frequent (13% of the total number of fractures). It seems that the best treatment for the displaced fractures is fixation. Various methods have been used, such as plates and screws, wires, IM-nailing, external fixation. The main problems are adhesions of extensor tendons, scarring and stiffness of the joints.

The purpose of this study is to examine the efficacy of internal fixation using Kirschner wires, applied open or closed, treating metacarpal and phalangeal fractures.

MATERIALS AND Methods: Between 1998 and 2005 145 out of a total of 2848 (5.2%) metacarpal and phalangeal fractures underwent operative treatment. Fixation was achieved by placing extrarticularly two or more Kirschner wires.

The wires were removed after 4 weeks and patients underwent physiotherapy for 2 to 4 weeks. The follow-up period was 3 – 15 mos (average 12 mos) and total range of movement and function of the injured hand was evaluated.

Results: Bone union was evident in 3 to 5 weeks. Range of movement was approximately 90% of normal, except for cases of comminuted intraarticular fractures and also in 6 cases of elderly non-cooperative patients.

One case of infection, complicating a metacarpal fracture and well responding to antibiotic treatment, was recorded. Three further infections resulted after neglected intraarticular fractures, all of which underwent arthrodesis. No rotational deformities were observed. There was no mechanical failure of the fixation in any case.

Conclusion: The fixation of metacarpal and phalangeal fractures using K-wires seems to be a useful method minimally invasive, stable and well tolerated by the patient, not interfering with the mobility of the joints. K-wires are easily removed and of low cost. The functional outcome of this method seems to be quite satisfactory.
