Wrist arthrodesis and soft tissue rebalancing in the spastic hand

Abstract

The aim of the present study was to investigate the outcomes of wrist arthrodesis with simultaneous soft tissue rebalancing of the digits in the spastic wrist. In 43 wrists (40 patients) the surgical goals, patient selection, procedures and outcomes were assessed. Preoperatively, mean passive extension was to 44° below neutral and only two patients had volitional control. Postoperatively, 33 and 10 cases reported excellent and good outcomes, respectively. A mean Goal Attainment Score of 62.4 indicated better than expected outcomes. In total, 37 hands required simultaneous finger rebalancing: 24 underwent tendon transfers and 13 surgical releases. A total of 12 thumbs required tendon transfers, three soft tissue releases and five metacarpophalangeal joint stabilization. Ten patients experienced complications, most commonly wound problems and implant failure, predominantly observed in patients with severe wrist and elbow contractures. In conclusion, wrist arthrodesis with simultaneous soft tissue rebalancing of the digits offers a viable approach in patients with severe spasticity. Cautious patient selection and consideration of potential complications are crucial for good outcomes. Level of evidence: IV
