Trapeziometacarpal joint osteoarthritis surgicaltreatment with andwithout suspension technique results comparison: a prospective cohort study

Rationale. Trapeziometacarpal joint osteoarthritis is a widespread hand joints pathology in the general population of people. Th s surgical treatment often consists in affected trapezium removal with reconstructive techniques implementation that ensure affected hand fi st fi ger stability. These surgical interventions results dissatisfaction lies in fi st metacarpal bone base migration and, as a result, pain syndrome recurrence.Th purpose is to compare the distance between fi st metacarpal bone base middle and scaphoid distal pole in patients after rhizarthrose surgical treatment using fi st carpometacarpal joint resection suspension interposition autotendoplasty method with patients indicators who additionally used a suspension technique.Materials and methods. In City Clinical Hospital №29 named N.E. Bauman upper limbs surgery department from 2017 to 2022 85 patients with fi st carpometacarpal joint osteoarthritis according to Eaton-Littler’s and Kellgren-Lawrence’s classification system (stage II-IV) surgical treatment was performed. 52 patients underwent fi st carpometacarpal joint resection suspension interposition autotendoplasty, while in case of 33 patients the suspension technique was not used. Treatment results evaluation was carried out of X-ray data 12 months after surgery.Results. In fi st carpometacarpal joint resection suspension interposition autotendoplasty group a slight the distance between fi st metacarpal bone base middle and scaphoid distal pole decrease was observed: by 12,3% from the original index - while in suspension component absence group a pronounced fi st metacarpal bone base proximal migration was observed: by 38,8% compared with X-ray gap preoperative indicators .Conclusion. Resection suspension interposition autotendoplasty use is an effective way to maintain the joint height.
