I second Chino's recommendation of the Level's. I have the women's version "Level Butterfly" - the men's is "Level Fly" I believe. In addition to providing wrist protection they are seriously the warmest gloves ever. They have a steam hole on the back and even still my hands are verging on hot on even the coldest days. Fortunately the liner comes out for drying each night.
I fully sympathize with you. My friend came out with me the other day and unfortunately for her, dismissed my dire warnings about helmets and wristguards. She was in a lesson and when I went to catch up with her I had to track her down at Ski Patrol. Two full days in two separate hospitals later she also has several pins in her wrist and is out of commission. The tragic part is she actually listened to me enough to bring her rollerblading wristguards up but chose not to wear them.
