Instability in the wrist can be caused by a torn Scapholunate ligament. The Brunelli Procedure does not fix the torn ligament. A hole is drilled through the Scaphoid bone and a part of a tendon taken from the patient is put through this hole and attached to the nearby bones. The procedure usually results in reduced movement of the wrist.
If the pain and instability persists, one could undergo an open surgery to reconstruct the scapholunate ligament. The lunotriquetral shear test may also be used. Arthroscopy is until today in an experimental stage but research suggest that in the near future it will be a reasonable alternative for open surgery due to faster recovery time. [6]
X-ray images indicate scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation. [7] A static scapholunate 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 ...
An arthroscope can be used at the time of fixation to evaluate for soft-tissue injury and the congruity of the joint surface and may increase the accuracy of joint surface alignment [19] Structures at risk include the triangular fibrocartilage complex and the scapholunate ligament. Scapholunate injuries in radial styloid fractures where the ...
In one randomized trial comparing trapeziectomy alone with trapeziectomy with ligament reconstruction and trapeziectomy with ligament reconstruction and tendon interposition, patients evaluated 5 to 18 years after surgery had similar pain intensity, grip strength and key and tip pinch strengths after each procedure.

In part based on these concerns, some surgeon prefer to maintain the lunate in patients younger than 40 years proximal row carpectomy. [6] [18] A surgery called four-corner arthrodesis is an option. [6] The capitate, lunate, hamate and triquetrum are fused together in this procedure and the scaphoid is excised.
(Reuters) - Alphabet's self-driving unit, Waymo, said on Friday it had closed a $5.6 billion funding round led by the Google parent, as it looks to expand its autonomous ride-hailing service.
Scapholunate advanced collapse (also known as SLAC wrist) is a type of wrist osteoarthritis. SLAC wrist is the most common type of post-traumatic wrist osteoarthritis [ 1 ] and is often the result of an undiagnosed or untreated scapholunate ligament rupture. [ 2 ]
