K-wire to brace the joint. The<unk><unk>  ligament is an important stabilizer of the<unk> .<unk>  instability resulting from disruption of the UCL profoundly impairs the overall function of the involved hand. Because of this, it is critical that these<unk> es receive appropriate attention and treatment. In most cases of a complete tear, the aponeurosis of the adductor pollicis muscle may be interposed between the bones of the MCP joint and the torn ligament. When this condition (referred to as a Stener lesion) occurs, the adequate healing of the tear is prevented altogether. For a Stener lesion to occur, a complete tear of the<unk><unk>  ligament must be present. However, the Stener lesion can occur even in the absence of a tear of the accessory<unk>  ligament or volar plate. The Stener lesion is present in more than 80% of complete ruptures of the UCL of the<unk> . When approaching this type of<unk> , the physician must first determine whether there is an incomplete rupture (or sprain) of the UCL, or a complete rupture. If the UCL is completely disrupted, the physician must then determine whether there is interposition of the adductor aponeurosis (Stener lesion), or simply a complete rupture of the UCL with anatomic or near-anatomic position. Radiographs are helpful in determining the possible presence of an avulsion fracture of the proximal phalanx insertion site of the<unk><unk>  ligament. Stress examination, or one done under fluoroscopic guidance, can help determine the integrity of the ligament. Most gamekeeper's<unk>  partial<unk> es are treated by simply immobilizing the joint in a<unk>  spica splint or a modified wrist splint and allowing the ligament to heal. However, near total or total tears of the UCL may require surgery to achieve a satisfactory repair, especially if accompanied by a Stener lesion.
