Tears of the ulnar collateral ligament (UCL) of the thumb metacarpophalangeal joint (MCP) are among the most common injuries of the hand. Skier's thumb refers to acute injury due to trauma, from hyperabduction of the thumb as it is caught by the ski pole strap. 6
Gamekeeper's thumb refers to chronic non-traumatic overuse injury (stress and repetitive trauma) that gradually injure the UCL.Repetitive injury of the ulnar collateral ligament of the thumb metacarpophalangeal joint caused when the gamekeeper broke the neck of game, using their thumb, index finger and the ground, leading to eventual tear of the ligament. METHODS: Between September 2008 and October 2011, 14 patients with ulnar collateral ligament avulsion fracture of the thumb metacarpophalangeal joint were treated using a combination of Kirschner wire and silk tension band. Sports injuries accounted for most of the remaining injuries, with only 2.4% acquired as a result of skiing injuries.The ulnar collateral ligament is an important stabilizer of the thumb.
Injury to the Ulnar Collateral Ligament of the Thumb. The adductor aponeurosis will not slide freely over the UCL on passive thumb IPJ flexion in a Stener injury.MRI is increasingly used to assess x-ray occult injuries to the ulnar collateral or to attempt to identify a.Treatment depends on classification but essentially surgical treatment is offered to patients with:It was first described in, you guessed it, Scottish gamekeepers, by,ADVERTISEMENT: Supporters see fewers/no ads,{"url":"/signup-modal-props.json?lang=us\u0026email="},{"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":1367,"mcqUrl":"https://radiopaedia.org/articles/gamekeepers-thumb-2/questions/1310?lang=us"}.ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers.Figure 3: gamekeeper thumb and Stener lesion,Case 14: with proximal phalanx shaft fracture,Gustilo Anderson classification (compound fracture),longitudinal versus transverse petrous temporal bone fracture,naso-orbitoethmoid (NOE) complex fracture,cervical spine fracture classification systems,AO classification of upper cervical injuries,Roy-Camille classification (odontoid process fracture ),subaxial cervical spine injury classification (SLIC),thoracolumbar spinal fracture classification systems,AO classification of thoracolumbar injuries,thoracolumbar injury classification and severity score (TLICS),Rockwood classification (acromioclavicular joint injury),Neer classification (proximal humeral fracture),AO classification (proximal humeral fracture),Milch classification (lateral humeral condyle fracture),Weiss classification (lateral humeral condyle fracture),Bado classification of Monteggia fracture-dislocations (radius-ulna),Mason classification (radial head fracture),Frykman classification (distal radial fracture),Hintermann classification (gamekeeper's thumb),Eaton classification (volar plate avulsion injury),Keifhaber-Stern classification (volar plate avulsion injury),Judet and Letournel classification (acetabular fracture),Harris classification (acetebular fracture),Young and Burgess classification of pelvic ring fractures,Pipkin classification (femoral head fracture),American Academy of Orthopedic Surgeons classification (periprosthetic hip fracture),Cooke and Newman classification (periprosthetic hip fracture),Johansson classification (periprosthetic hip fracture),Vancouver classification (periprosthetic hip fracture),Winquist classification (femoral shaft fracture),Schatzker classification (tibial plateau fracture),Lauge-Hansen classification (ankle injury),Danis-Weber classification (ankle fracture),Berndt and Harty classification (osteochondral lesions of the talus),Sanders CT classification (calcaneal fracture),Hawkins classification (talar neck fracture),anterior superior iliac spine (ASIS) avulsion,anterior cruciate ligament avulsion fracture,posterior cruciate ligament avulsion fracture,avulsion fracture of the proximal 5th metatarsal.
Gamekeeping and poaching have largely fallen by the wayside as a recreational activity. 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. A complete tear or avulsion fracture requires surgical repair. The term “bony skier’s thumb” may be used to describe a UCL avulsion fracture. Clearly, this requires a knowledge of local anatomy and the use of a high-frequency MSK probe. Thumb instability resulting from disruption of the UCL profoundly impairs the overall function of the involved hand. There were 8 males and 6 … The distal attachment site to the proximal phalangeal base is the most common site of avulsion.The aim of imaging is to define any fracture, determine if there is instability (joint space widening), and identify a.If a small avulsion fracture is present, then this could be seen at the ulnar corner of the base of the proximal phalanx or ulnar first metacarpal head.
