Brief definitions to orthopedic terminology arranged topically in 12 chapters. Longstanding scaphoid nonunion or scapholunate ligament injuries can lead to carpal collapse. SLAC is an osteoarthropathy of the carpus secondary to altered stress around an unstable scaphoid. It is now recognized that SL instability is a spectrum of injury rather than an all-or-none condition (Table 1).7,27–29Scapholunate in- stability is defined as a wrist that is symptomatic during mechanical and load-bearing activities, demonstrating abnormal kinematics during motion.30 Other causes include Kienböck disease, chondrocalcinosis [ 3 ], and other carpal fractures. Hence, most doctors prefer to operate upon a symptomatic SLAC. SLAC of the wrist: SLAC stands for S caphoid L unate A dvanced C ollapse. Bookshelf Wrist osteoarthritis is a common condition that can lead to substantial functional impairment [9, 19].One of the most common causes of wrist osteoarthritis involves the radioscaphoid and capitolunate joints in what is known as the scapholunate advanced collapse (SLAC) wrist [17, 18].Watson and Ballet first coined the term SLAC wrist in their seminal paper in 1984 [].

NATO conferences such as this symposium on Biomechanics of the Hand and Wrist provides such a basis upon which to build discernment of fundamental postulates. Reports of 7,000-year-old prehistoric humans with SLAC wrists show that this pathological process has been ever-prevalent in our species. Mortons Neuroma is a compressive neuropathy of the interdigital nerve, usually between the third and fourth metatarsals. Trigger finger is a Stenosing tenosynovitis caused by inflammation of the flexor tendon sheath, it happened mostly at the level of the A1 pulley. The Watson and Ballet classification of SLAC wrist osteoarthritis was designed to aid communication between professional and researchers as well as to aid treatment planning. In the present study, the interrater reliability of SLAC wrist stage classification by means of X-ray image analysis was evaluated between radiologists and hand surgeons. In stage I, the earliest osteoarthritic changes will differ among SLAC and scaphoid nonunion advanced collapse (SNAC) wrists.
