Scapholunate instabilities are the most common wrist instability and can be a serious issue, so it's important that you can give your injured wist the support it needs. Our range of Wrist Supports for Scapholunate Instability has been chosen by product experts and developed to help reduce pain and aid recovery.

Scapholunate dissociation Power Point 1. 46yo for most cases will need operative repair of interosseous ligament. Can place patient in thumb spica splint and have patient f/u with ortho within one week. Untreated, SLD can lead to DISI,

Scapholunate occurs when the scapholunate ligament is completely torn or stretched, allowing the scaphoid and lunate bones to separate or disassociate. The scaphoid may then tilt in a rotatory direction (volar), whereas the lunate bone tilts in a dorsal direction. This allows the two carpal bones to not only separate, but tilt away from each other. Scapholunate Dissociation The spacing between all carpal bones should be 1-2 mm, look for the "Terry Thomas" sign to diagnosis scapholunate dissociation.

Use 3-4 portal as the viewing portal and 4-5 portal as the working portal. 7. Clean inﬂammatory tissue from the dorsal portion of the scapholunate interosseous ligament. 8. Perform cruentation of the insertion of the scapholunate interosseous ligament.

In cases where the scapholunate ligament tears have not resulted in a complete disassociation, ligament fraying, thinning and/or irregularities result in an elongated ligament, which increases carpal space. 2021-01-07 · The mild disease needs only non-operative treatment such as NSAIDs, wrist splints and corticosteroid injections with operative management indicated for more complicated cases. This activity illustrates the evaluation and management of scapholunate advanced collapse and explains the role of the interprofessional team in improving care for patients with this condition.

This is known as “scapholunate dissociation.” The bones also rotate abnormally after SL ligament tears, with the scaphoid rotating forward, and the lunate rotating backwards. This condition is known as “dorsal intercalated segmental instability” or “DISI” deformity.

Rupture of the scapholunate ligament is the first event in any sequence of perilunar ligament ruptures. It is the most common pattern of wrist instability. Its characteristics are the dissociation of the scaphoid and the lunate, with flexion of the scaphoid, and extension of the lunate.

The all-dorsal scapholunate reconstruction technique with InternalBrace ligament augmentation and the 3.5 mm DX SwiveLock® SL anchor is recommended for dynamic and static scapholunate instability where the carpus remains reducible and arthrosis is not present. The goal of the reconstruction is to repair the torn

We discuss a type of wrist injury called a "SL dissociation" also known as a Lavernia CJ, Cohen MS, Taleisnik J: Treatment of scapholunate dissociation by Jan 31, 2017 Scapholunate dissociation is the most common form of carpal instability. After suture of the capsule and the incision, a dorsal forearm splint is Phase III: (6 to 12 weeks after surgery). Goal: Initiate ROM. 1. Cast Removed. 2. Stabilization pin removed in clinic.

A static instability is generally readily visible, but a dynamic scapholunate instability can only be seen radiographically in certain wrist positions or under certain loading conditions, such as when clenching the wrist, or loading the wrist in ulnar The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two. of hand or wrist OA.2 Scapholunate advanced collapse (SLAC) is a frequently encountered form of wrist OA that typically ensues from scapholunate ligament injury.3 In fact, SLAC is the most common etiology of wrist OA, accounting for approximately 55% of all individuals with wrist arthritis.4 Conservative treatment for alleviating wrist OA pain in- Scapholunate dissociation is the abnormal orientation or movement of the small bones of your wrist, the scaphoid and lunate bones in relation to one another. Dr Sellers offers treatment for this condition in Wetumpka, Prattville and Montgomery, AL. 2020-04-14 Scapholunate Ligament Reconstruction/Repair Mr. Matthan Mammen MS, FRACS (Orth) Orthopaedic Surgeon o Change to splint o Shoulder and elbow range of movement exercises Late phase (>6 weeks) Goals o Regain function of wrist o Regain strength, proprioception and function 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. 26 About 13.4% of distal radius fractures are associated with scapholunate dissociation.

in this video we talk about the radiologic findings, diagnosis, treatment, and complications of scapholunate dislocation.

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. 5. Evaluate and classify scapholunate instability from radiocarpal and midcarpal portals.
