The ulnar collateral ligament connects the head of the ulna to the pisiform at the wrist junction. It is this articulation that provides much needed stability to the wrist joint. But, if it is torn, the injury has farther reaching effects than what it initially seen, and this is due to the fact that the pisiform attaches to the fourth and fifth digits of the hand via the pisohamate ligament and the pisometacarpal ligament.
Because the pisiform has ligaments on each side, and is used as an anchoring mechanism for stability, the detachment of the ulnar collateral ligament now causes instability in the metacarpals as well as the fourth and fifth digits, even though the other two ligaments are still attached. The reason for this is that since the tension was been removed between the pisiform and ulna, there will now be slack in the other two ligaments as the pisiform drifts towards the ligaments that are still attached.
To help address this injury without surgery and increase wrist joint stability, a number of specific exercises are performed to enhance strength of the soft-tissues surrounding the ulnar side of the wrist joint, which in turn reduces symptoms, like wrist and elbow pain.
