Are Rehabilitation Results in Flexor Tendon Zone II Injuries as Bad as Feared?

Tendon cuts constitute a significant portion of hand injuries. Today, most flexor tendon ruptures are repaired the same day as the injury or a few days later. Rehabilitation after flexor tendon repair is at least as important as surgical repair. Hand rehabilitation protocol after tendon repair; It consists of four periods: 1-4 weeks early period, 4-6 weeks early intermediate period, 6-8 weeks intermediate period, 8-12 weeks late period. Modified Duran Protocol is one of the earliest passive mobilization methods. According to this protocol, it has been reported that 3-5 mm of passive movement of the tendon anastomosis is effective in preventing tendon adhesions. In the literature, the number of studies examining rehabilitation results in patients with flexor tendon zone II injuries is quite limited. Post-operative rehabilitation results are worse in patients with zone II tendon injuries compared to other flexor zone injuries. This study aimed to investigate the early rehabilitation results of patients who underwent a rehabilitation program after Zone II flexor tendon injury by comparing the improvements in joint range of motion, pain, functionality and quality of life with other zone injuries. 70 patients who applied to Ankara City Hospital Physical Therapy and Rehabilitation Hospital Traumatic Hand Clinic due to flexor tendon injury and met the inclusion criteria for the study will be included. Demographic characteristics of the patients (age, gender), occupation, cause of injury, injured hand, dominant hand, smoking, and injury zones will be recorded. Patients with zone II injuries Group I, Patients with other zone injuries will be divided into Group II. In this study, Modified Duran early passive mobilization protocol was used to protect the repaired tendon and reduce the risk of adhesion will be followed. The physiotherapist will advised each patient on the things to consider after the operation, orthosis use and care, and the rehabilitation process. Early passive mobilization exercises in the form of passive flexion and extension and edema massage will be taught to all fingers of the injured hand in a dorsal blocking orthosis and will be recommended to be applied every two hours during the day. Patient follow-up will last four weeks and afterwards, measurements will be repeated.
