顕微鏡下Dupuytren拘縮手術は神経血管損傷を予防できるか？

抄録

  There are few reports on the use of surgical microscop in the treatment of Dupuytren’s contracture; however, it has been consistently used at our department. We aimed to investigate the usefulness of surgical microscop in preventing iatrogenic neurovascular injuries during limited fasciectomy for Dupuytren’s contracture. Twenty-four patients with Dupuytren’s contracture who underwent limited fasciectomy between April 2012 and March 2022 and were followed up for at least 3 months were included. Postoperative complications included neurapraxia in two patients (8.3%) and nerve injury in one patient (4.2%) . There were no arterial injuries. We found that the incidence of neuropraxia and arterial injury were lower than the median reported in previous studies. Our findings suggest that surgical microscopy is useful for preventing neurovascular complications during surgery for Dupuytren’s contracture. In addition, surgical microscop has the advantages of facilitating immediate nerve and arterial repair in cases of nerve or arterial injury and easy identification of the boundary between the cord and normal tissue.
