Treatment of subcapital fractures of the fifth metacarpal bone: a prospective randomised comparison between functional treatment and reposition and splinting. Immediate mobilization gives good results in boxer's fractures with volar angulation up to 70 degrees: a prospective randomized trial comparing immediate mobilization with cast immobilization. The use of a moulded metacarpal brace versus neighbour strapping for fractures of the little finger metacarpal neck. Functional taping of fractures of the 5th metacarpal results in a quicker recovery.
We did a prospective study to compare the results of treatment of subcapital fractures of the fifth metacarpal bone by closed reduction and splinting or by functional treatment. Twenty-nine consecutive patients were randomly divided into the two treatment groups (functional n = 14, and reposition and splinting n = 15). The results of treatment were satisfactory in both groups. Functionally treated patients recovered their grip force and range of movement of the affected hand a little sooner. All fractures in both groups had united within three months. There were no complications. We conclude that subcapital fractures of the fifth metacarpal bone can successfully be treated without closed reduction and splinting. The management of the subcapital fracture of the fifth metacarpal bone, the boxer's fracture, is still a matter of debate. Besides the question of which rate of angulation is acceptable before a reduction becomes necessary, recommendations for further treatment of this fracture vary as well. Therefore, the aim of our study was to compare randomly and prospectively the results of an immobilization treatment for 3 weeks with cast with a functional treatment, all with accepted angulations up to 70 degrees.
                Between June 1997 and June 1998, 40 patients were randomly allocated either to treatment with an ulnar gutter plaster cast for a period of 3 weeks followed by mobilization, or a pressure bandage for 1 week and immediate mobilization within limits imposed by pain. All patients were monitored at the outpatient clinic 6 and 12 weeks after the fracture. Clinical outcome was measured by the range of motion (ROM) of the fifth metacarpal phalangeal (MCP) joint, and by interviewing the patients about their satisfaction, pain perception, return to work and hobby, and need for physiotherapy.
                A total of 35 patients with a mean age of 29 years (range 15-84) completed the required follow-up program. The mean angulation of the fracture was 39 degrees (range 15-70 degrees ). Between the two groups, no statistical differences were scored with respect to ROM, satisfaction, pain perception, return to work and hobby, and need for physiotherapy. According to a sample size calculation (power 90%, alpha 0.05, to detect 5 degrees difference in ROM), 12 patients needed to be included in each group to reach significance.
                A pressure bandage for 1 week, followed by immediate mobilization, is a sufficient alternative treatment for a boxer's fracture, if it is not angulated greater than 70 degrees and not rotated. This treatment resulted in satisfied patients who perceived no more pain and had a good ROM of the fifth MCP joint. Reduction of angulated fractures of less than 70 degrees seems not of value, with respect to ROM of the fifth MCP joint. Seventy-three patients with fractures of the neck of the little finger metacarpal were randomized to treatment with a moulded metacarpal brace or neighbour strapping. Sixty-five of these attended for follow-up at 3 weeks. Both treatment modalities permitted a functional range of movement, but patients treated with the metacarpal brace had significantly less pain than those treated with neighbour strapping, and this facilitated an early return to work.
                Copyright 2001 The British Society for Surgery of the Hand. Fractures of the fifth metacarpal can be treated non-operatively by plaster immobilisation or functional taping. In order to evaluate the better treatment policy, the two methods were compared in a prospective randomised series. We treated 25 patients with an ulnar gutter plaster-cast splintage and 25 with functional tape. Functional recovery was evaluated after one week and four weeks, three months and six months. Mobility, power-grip, pulling- and torque strengths were measured. The change in fracture angulation was calculated at the one and four-week follow-up. Residual symptoms were evaluated after six months. The functional tape group showed significant earlier functional recovery. After six months, there were no significant differences between the groups with regard to functional and anatomical results or the number of patients with residual symptoms. In both groups, we noted a change in fracture angulation only in those fractures that had been reduced. We conclude that fractures of the 5th metacarpal are better treated by functional taping than by cast immobilisation.
No included studies reported our primary outcome measure of interest, validated hand function. There was heterogeneity between the studies, which were of limited quality and size. Consequently, no single non-operative treatment regimen for fracture of the neck of the fifth metacarpal can be recommended as superior to another. Further research is definitely warranted.
