OBJECTIVE: In this study, we aimed to evaluate the effectiveness of the modified Kessler technique in managing spaghetti wrist lacerations by multidisciplinary treatment.

PATIENTS AND METHODS: Patients who were operated and followed up with the diagnosis of spaghetti wrist tears in our clinic between January 2012 and December 2020 were included in the study. In the postoperative follow-ups, the parameters evaluating the functionality of the patients were examined.

RESULTS: Patients were 105 male (86.7%) and 16 women (13.2%), with a mean age of 36.83 ± 16.38 years. At the final follow-up, functional outcomes were assessed. The most common injury mechanism was glass-related injuries (35.5%). The mean starting surgery time of the patients was 4.64±2.98 hours. The most frequently involved structures were the palmaris longus with a rate of 51% and the flexor digitorum superficialis with a rate of 45%. There were significant differences regarding intrinsic function and grip strength between male and female patients (p = 0.04, p = 0.21, respectively). There were significant differences regarding sensation and grip strength between smoker and nonsmoker patients (p = 0.03, p = 0.01, respectively). The number of the damaged structures was negatively correlated with postsurgical functional outcomes of four tests, including tendon function, opposition, intrinsic function, and grip strength. The physical therapy period was correlated to hand function tests (r = 0.756, p < 0.05). Nerve damage was negatively correlated with sensation (p = 0.011, r = -0.932).

CONCLUSIONS: The modified Kessler technique is reliable with functional outcomes for spaghetti wrist injuries involving tendons, nerves, and arteries. Meticulous and early surgical treatment within the first 8 hours of spaghetti wrist injury and early initiation and long-term physical therapy are vital in patients’ functional outcomes.
