Home exercises after volar locking plate fixation for distal radius fracture in the elderly are as effective as supervised physiotherapy -multicenter retrospective study-

Although home exercises are used for postoperative rehabilitation of distal radius fractures (DRF), the superiority of home exercise over supervised physiotherapy rehabilitation is controversial. This study aimed to compare the function of home exercise and supervised physiotherapy rehabilitation during postoperative rehabilitation for DRF. We conducted a multicenter, retrospective study in which we included 1949 patients over 65 years old who underwent volar locking plate fixation for DRF. After propensity score matching, 308 patients were assigned to each of an independent home exercise group (IHG) and supervised physiotherapy group (SPG). Wrist function was assessed after 3, 6, and 12 months postoperatively. The results showed that the Mayo Wrist Score did not differ significantly within the observation period. Range of motion of the wrist was better in the SPG up to 3 months postoperatively but was almost the same as that in the IHG at 6 months. However, the Numerical Rating Scale score was lower in the IHG during all observation periods. Home exercise may be as effective as supervised physiotherapy in the medium term, but supervised physiotherapy rehabilitation should be considered if early recovery and good wrist function are desired.
