The arthroscope is in the 6R portal, with direct vision of the dorsal portion of the scapholunate ligament (SLL) in a left wrist. (A) We introduce the anchor through the 3-4 portal and place it at the dorsal edge of the scaphoid or lunate according to the spot where the ligament has been In scapholunate dissociation, the best results are obtained at the acute stage or vision of the dorsal portion of the scapholunate ligament (SLL) in a left wrist. Case: 32 year old male left wrist – pain and clunking in radial side of wrist. See Imaging below: Xray Wrist: Figure 1 – AP SL no widening Figure 2 – Lateral A 26-year-old, right-handed professional soccer player wrist pain. On examination, the scapholunate joint is tender dorsally and a painful, palpable snap is What is Scapholunate Dissociation? Scapholunate dissociation is the abnormal orientation or movement of the small bones of your wrist: the scaphoid and lunate , The scapholunate (SL) dissociation, or lesion of the SL ligament, is the most common form of carpal instability Eight right and six left wrists were operated on.

Many other investigators report improvements in scapholunate alignment and improvement in pain relief and function with a loss of wrist flexion as a tradeoff. However, despite technical advances in surgical technique and intraoperative improvement of alignment and gapping, these results may diminish by the 2- to 3-year postoperative period. 2019-11-16 Scapholunate dissociation Power Point 1.  46yo male presents with chief complaint of left wrist pain. Patient slipped on side walk on sheet of ice and fell forward, landing on outstretched hand.

With the arthroscope in the midcarpal ulnar portal and the probe in the midcarpal radial portal for the left wrist, the stability of the scapholunate joint is checked. (L, lunate; S, scaphoid.) Table 1. Scapholunate advanced collapse (SLAC) is a type of arthritis related to scapholunate dissociation.

Our ligaments connect one bone to another. They keep our bones in alignment and they prevent our bones from wobbling all over the place. Scapholunate dissociation represents a portion of a perilunar dislocation or The lesions of the scapholunate ligament are some of the most frequently encountered in the wrist. Left Case: 32 year old male left wrist – pain and clunking in radial side of wrist See Imaging below: Xray Wrist: Figure 1 – AP SL no widening Figure 2 – Lateral (normal Scapholunate angle 30-60 deg)2 Figure 2 – Clenched fist view: Allows clinician to assess scapholunate stability. Widening of Scapho-Lunate interval. 2020-07-01 · The scapholunate advanced collapse [SLAC] pattern of carpal osteoarthritis was first described by Watson and Ballet in 1984 as the most common form of human wrist arthritis. This repetitive sequence of degenerative changes is based on and caused by articular alignment problems between the scaphoid, the lunate, and the radius.

This is also known as a DISI (Dorsal Intercalated Segmental Instability) injury. (1,2) Scapholunate dissociation. Scapholunate dissociation is the most common carpal instability. Scapholunate instability is associated with increased scaphoid flexion and pronation with associated lunate extension.

With the arthroscope in the midcarpal ulnar portal and the probe in the midcarpal radial portal for the left wrist, the stability of the scapholunate joint is checked.

Other The aching, dull and stiff pain in her left wrist gradually started one year prior. Diagnostic X‐ray examination showed severe degenerative joint disease of the left wrist with scapholunate dissociation, scapholunate ligament tear, and avascular necrosis of the lunate (Figure 1).

Xray indicates scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation. 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 deviation.

DISI (dorsal intercalated segmental instability) scapholunate dissociation causes the scaphoid to flex palmar and the lunate to dorsiflex; if left untreated the DISI deformity can progress into a SLAC wrist Case: 32 year old male left wrist – pain and clunking in radial side of wrist See Imaging below: Xray Wrist: Figure 1 – AP SL no widening Figure 2 – Lateral (normal Scapholunate angle 30-60 deg)2 Figure 2 – Clenched fist view: Allows clinician to assess scapholunate stability. Widening of Scapho-Lunate interval.

Dissociation between the carpal scaphoid and lunate is the most common pattern of wrist instability. 1 – 3 Because scapholunate dissociation leads to progressive degenerative arthritis of the wrist, 2, 4, 5 reduction and internal fixation is the preferred method of treatment, particularly in the acute setting. 6 – 10 Owing to the small surface area and the high loads placed on Shown is the right hand, palm down (left) and palm up (right). A=Scaphoid, B= Lunate. From, scaphoid.
