PURPOSE To determine the value of ultrasound (US) in recognizing the ligamentary dislocation occasionally associated with gamekeeper thumb (Stener lesion). Detecting such dislocations is important because they require surgical repair, whereas nondisplaced ruptured ligaments respond to conservative treatment. This dislocation cannot be reliably diagnosed with standard methods, leading to unneces...

A 37-year-old man presented to our clinic after sustaining a low-speed motorcycle accident. He suffered minor facial abrasions and pain at his right thumb metacarpophalangeal (MCP) joint consistent with a gamekeeper injury. He was placed in a splint for several weeks; however, he had persistent pain and was thus evaluated with an MRI (magnetic resonance imaging) revealing a torn ulnar collatera...

The evaluation and treatment of injuries of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb remain controversial. In a retrospective study that was done to assess our ability to determine whether displacement of the ligament (a Stener lesion) was present, we reviewed our accumulated experience with patients who had an injury of this ligament who were treated surgical...

The ulnar collateral ligament (UCL) of the thumb metacarpophalangeal joint is a static stabilizer that may rupture from a hyperabduction injury. Although some UCL tears may heal with immobilization, outcomes are worse for Stener lesions, in which the proximal ligament stump slips out from beneath the adductor pollicis aponeurosis and is entrapped proximal and superficial to the aponeurosis, pre...

Medial collateral ligament tears usually will be treated through non-surgical methods, but, in some cases such as those with tears at the distal insertion where the reduction could be blocked by the pes anserine tendons (Stener-like lesion), surgery will be performed. Here, we present a surgical technique in such cases. In this retrospective case series, we describe six patients diagnosed with ...

Injuries to the ulnar collateral ligament of the metacarpophalangeal (MCP) joint of the thumb are relatively common. When an incomplete rupture is present, valgus stress testing with the MCP joint positioned in extension reveals minimal or no instability (less than 30 degrees of laxity or less than 15 degrees more laxity than in the noninjured thumb). When a complete rupture is present, valgus ...
