Detailed step by step desription of ORIF of Lunotriquetral dissociation for Perilunate, After emergency reduction, the wrist is immobilized in a plaster splint, or cast (Colles), In most of the cases, the scapholunate (SL)

Nonoperative treatment is so frequently followed by redisplacement and later carpal derangement that ligament repair is mandatory. UVA Professor, Dr. Nicole Deal, presents a surgical technique for repair of a scapholunate ligament disruption. Wrist: Scapholunate dissociation is caused by scapholunate ligament tear which creates widening of scapholunate space. This is the most common ligament injury of the wrist which if untreated may lead to dorsal intercalated segment instability (disi) and scapholunate advanced collapse (slac). Scapholunate Advanced Collapse Pattern of Osteoarthritis Chronic scapholunate dissociation leads to a predictable pattern of degenerative changes in the radiocarpal and midcarpal joints. The incongruent joint surfaces between the radius and malrotated scaphoid, as well as those between the head of the capitate and dorsiflexed lunate, lead to osteoarthritis.

Slater RR Jr, Szabo RM, Bay BK, Laubach J. Dorsal intercarpal ligament capsulodesis for scapholunate dissociation: biomechanical analysis in a cadaver model. 2019-10-11 · INTRODUCTION. While not common, lunate fractures and perilunate injuries have important potential consequences. They are most often sustained from a fall onto an extended wrist or some other wrist hyperextension injury. The scapholunate ligament is the most frequently injured ligament in the wrist, so is a common cause of wrist "sprains". A significant injury can alter the way the small bones of the wrist interact, and this can lead to cartilage wear and osteoarthritis. Perilunate and Lunate Dislocations - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the MSD Manuals - Medical Professional Version.

They are most often sustained from a fall onto an extended wrist or some other wrist hyperextension injury.

Scapholunate dissociation; Cock-up or volar wrist splint; Outpatient follow-up with an orthopedist or hand specialist within 1 week; Perilunate or lunate dislocation; Consult an orthopedist or hand surgeon. Closed reductions are often unsuccessful.

Stage II describes displacement of the carpus relative to the lunate. The lunocapitate articulation may be disrupted resulting in a dorsal perilunate dislocation, or in the case of concomitant scaphoid fracture, the wrist may undergo a transscaphoperilunate dislocation. 2015-11-07 Scapholunate dissociation Power Point 1.

An acute complete tear of the ligament between the scaphoid and lunate bones commonly results from a forceful hyperextension injury to the wrist---for example after a fall onto an outstretched hand or a car accident. Scapholunate dissociation is a difficult and unresolved problem in orthopedic hand surgery. Scapholunate ligament repair alone leads to failure and progression of scapholunate advanced collapse If you had a recent scapholunate ligament injury, the early goal of treatment will be pain control. This may include wearing a wrist splint or cast, decreasing activity and resting the wrist.

Scapholunate dissociation: Involves a complete tear of the SLIL with additional tear of 1 or more secondary ligaments. The scaphoid usually rotates into flexion, and the lunate rotates into extension. This is apparent on plain static radiographs.

Perform cruentation of the insertion of the scapholunate interosseous ligament. 9. The position that a hand assumes holding a steering wheel has also been postulated as a possible predisposition for an SLL injury during a motor vehicle accident. 25 Dissociation of the scapholunate joint is the most frequent carpal instability.

Its characteristics are the dissociation of the scaphoid and the lunate, with flexion of the scaphoid, and extension of the lunate. An acute SL dissociation is shown--a gap greater than 3 mm between the scaphoid and lunate (see arrow) Acute SL dissociation results in a near vertical scaphoid--thus the normal angle increases to greater than 60 degrees Scapholunate dissociation normally causes pain in the wrist joint. This is typically felt in the back of the wrist when the wrist is moved or used.

Tenderness over scapholunate ligament, increased gap between scaphoid and lunate on plain 17 Apr 2002 ligamentoplasty for chronic scapholunate dissociation.
