title: [Functional bracing after operative treatment of metacarpal fractures].
abstract: Metacarpal fractures are frequently immobilized for several weeks in forearm plaster cast, even after operative stabilisation. The purpose of this study was to assess the results after early functional treatment using metacarpal braces. 87 patients with 105 metacarpal fractures were included in a prospective study from February 1997 until November 2000. The AO-classification of the fractures was assessed for all patients: n=33 A1,n=9 A2,n=3 A3, n=27 B1,n=6 B2,n=7 B3,n=10 C1,n=7 C2, n=3 C3.Exclusion criteria were tendon or nerve injuries,pathological fractures (tumor or metabolic),additional digital fractures of the same ray,and a patients age of less then 18 years. All fractures were treated operatively. 73 patients (84%) were recruited for follow up after an average period of nine months. Average grip strength reached 96% (Jamar II) for the power grip, 97% for the three finger and 98% for the pinch grip compared to the contra-lateral side in the group where the dominant hand was affected. It was 88% for the power grip, 91% for the three finger grip and 94% for the pinch grip after injury of the non-dominant hand. The mean postoperative pain score on the visual analog scale was 0.2 for resting conditions, 0.8 for motion and 2.2 under stress.A decreased total range of motion was observed in 15 of 73 patients (21%). The average DASH score reached 6.5 points. Physical therapy was required for an average of 6.7 weeks. Only 41% of the patients with early functional treatment required further physical therapy after removal of the brace. The metacarpal brace used in this series protects from direct trauma,and provides a high patients comfort.It has no disadvantages considering fracture retention compared to conventional plaster casts or splints. The need for physical therapy is reduced after functional fracture bracing.Thus, the metacarpal brace has proven to be a suitable tool for early functional treatment after operative stabilisation of metacarpal fractures.
