Analysis of Dupuytren’s contracture (DC) surgical treatment efficacy according to the Tatarstan Republic DC Register (258 patients, 343 hands) was performed. Partial wedge-shaped excision of palmar aponeurosis was the most common intervention on both the right and left hand. Late (1 year and over) postoperative complications (POC) — relapse, dissemination, progression were detected in 41.8% of patients at terms up to 15 years. Presence of POC on the operated hand caused disturbance of its function in 11.9% of cases on the right and 16.3% of cases on the left. Curability from DC made up 34.9 — 73.8% depending on the operated hand. Complete restoration of hand function was achieved in 22.2—100% of observations. Surgical treatment of DC enabled to ensure favorable patient’s condition at term 1 year and over in 67.5 and 59.9% of cases on the right and left hand respectively.

Dupuytren’s disease is an acute and multifaceted problem that affects not only medicine but also psychology, social life, since a person who has lost the ability to perform his/her socially significant functions experiences moral and physical suffering. From the first description of Dupuytren’s disease to the present, questions of etiology, pathogenesis, classification, treatment methods, and features of the preventive measures of this disease remain debatable. Therefore, the main goal of the paper was to analyze the technology for predicting the functional state of the hand after surgical treatment of Dupuytren’s disease (contracture). The study was conducted at the Department of Hand Microsurgery of the Republican Clinical Hospital of the Ministry of Health of the Republic of Tatarstan. The total number of patients under observation was 258, age 21-80 years. The research results were grouped into 6 combinations. It has been determined that three groups of factors affect the recovery degree: A (gender, age, examination period, severity); B (place of residence, physical and mental work, bad habits); C (surgeon's experience, types of operations, anaesthesia, section, skin plastic, reconstructive treatment, healing, etc.). It has been found that it is possible to achieve full restoration of the function of the wrist on the right hand in 67.5% of patients and on the left hand in 59.9% of patients in periods of more than one year.
