Background. Scapholunate advanced collapse (SLAC) is a common type of the wrist osteoarthritis. It is characterized by progressive deformity, instability and arthritis due to chronic dissociation of the scaphoid and lunate bones with chronic scapholunate interosseous ligament (SLIL) injuries. Quite often, in this pathology, it is difficult to alleviate the pain syndrome and preserve the range of motion. The aim of the review — based on the modern literature data, to analyse the concept and pathogenesis of scapholunate advanced collapse, current methods of radiological diagnosis and treatment modalities of the pathology. Methods. The search was performed in eLIBRARY and PubMed databases using the following keywords: scapholunate advanced collapse, SLAC, scapholunate instability, proximal row carpectomy. We selected 86 original articles and reviews out of 110 papers found. The selected ones reveal the issues of pathogenesis, radiological diagnosis and treatment of the pathology. Results. Scapholunate carpal collapse is secondary arthritis of the carpal bones resulting from rupture of the SLIL, which can be traumatic or non-traumatic. Conservative methods of the SLAC treatment can be used in the early stage of arthritis, but there is no data on their effectiveness in the world literature. Surgical treatment methods are varied, the choice depends on the clinical stage of the disease. Conclusions. The efficiency of conservative treatment modalities of the SLAC syndrome has not been proved yet. There is a plenty of surgical treatment methods and their modifications developed to alleviate the pain syndrome and preserve the motion and strength of the wrist grip as far as it is possible. However, the choice of the treatment method depending on the clinical stage of the disease is still problematic. For young active patients especially important is the development of adjuvant techniques aimed to increase the treatment efficiency. To date, there is accumulating evidence of successful use of pyrocarbon implants and arthroscopy techniques in the wrist surgery.
