The aim of this study was to determine whether psychological factors (depression, catastrophic thinking, and pain anxiety) and pain intensity are associated with choice of operative treatment. Ninety new patients with a ganglion cyst on their hand or wrist completed psychological questionnaires (Pain Catastrophizing Scale, Pain Anxiety Symptoms Scale, and Center for the Epidemiological Study of Depression instrument) and an ordinal measure of pain intensity. ⋯ Psychological factors were associated with pain intensity at enrolment, but not with treatment choice. Operative treatment did not result in less pain intensity or disability, or higher satisfaction compared with non-operative treatment.

How placement affects force and contact pressure between a volar plate of the distal radius and the flexor pollicus longus tendon: a biomechanical investigation.
Open reduction and internal fixation of a distal radius fracture can leave a volar plate in close proximity or touching the tendons of the wrist. This cadaveric study examines the how volar plate position changes contact pressure and force against the flexor pollicis longus (FPL) tendon in multiple wrist extension positions. ⋯ Multiple clinical case reports have described rupture of the flexor tendons associated with distally positioned plates or protruding screw heads, creating prominent or sharp edges. This study illustrates that in order to minimize contact pressure on the flexor tendons, plating distal to the watershed line should be avoided when possible.
