Development of de Quervain Tenosynovitis After Distal Radius Fracture

Abstract

Background:

We sought to determine the risk factors for the development of de Quervain tenosynovitis after distal radius fractures. Our hypothesis is that longer periods of immobilization and higher-energy fracture patterns will correlate with the development of de Quervain tenosynovitis.

Methods:

This is a 10-year retrospective study of 1451 consecutive patients with distal radius fractures presenting to a large academic institution. The incidence and relative risk of de Quervain tenosynovitis within 1 year of sustaining a distal radius fracture were analyzed.

Results:

In total, 41 patients developed posttraumatic de Quervain tenosynovitis at an average time of 6.5 months. In the operative cohort, the incidence was 2.2%, and that of the nonoperative group was 3.8%. Among all affected patients, 78% admitted to strenuous, overuse activities or careers. Compared with the unaffected cohort, the de Quervain tenosynovitis group was more likely to be female and black with similar age and body mass index. The traumatic cohort was less likely to respond to corticosteroid injections. A separate extensor pollicis brevis (EPB) sheath was noted in all patients requiring surgical release.

Conclusions:

Patients with a nonoperative distal radius fracture were 4.2 times more likely to develop de Quervain’s than the general population, and those treated operatively were 2.4 times more likely. These patients were more likely to be female, black, and engage in strenuous overuse activities or careers. They demonstrated higher-energy fracture patterns and worse response to corticosteroid injections, more frequently requiring surgical decompression. Among those requiring surgery, patients were 2.5 times more likely to have a separate EPB sheath than those with atraumatic Quervain’s.
