Objectives/Interrogation: There are different factors influencing the postoperative results of carpal tunnel syndrome. Our hypothesis was that patients with preoperative night pain will be more satisfied after the neurolysis of the median nerve than those without night pain.
Methods: A retrospective study was performed based on a prospective data collection. In the period 2014 and 2018 467 patients were operated in our unit for carpal tunnel syndrome, 29 were excluded due to missing data. In all cases open carpal tunnel release was performed without synovectomy. Changes in daytime numbness, nighttime numbness, night pain, and satisfaction was registered. For the evaluation of the subjective findings, a Visual analogue scale of 1-10 (VAS) was used. The patients were selected into 3 groups according to the level of preoperative night pain. Group 1 had no night pain prior the operation, group 2 had mild night pain (2-5 VAS) and group 3 had severe night pain (6-10 VAS). Significance was evaluated using Z-test (p=0,05).
Results and Conclusions: Group 1 had 77 patients (17,6%), group 2 had 74 patients (16,9%) and group 3 had 287 patients (65,5%). The average of preoperative night pain was 4 VAS in group 2 and 8,86 VAS in group 3. Patients with severe night pain complained of significantly higher level of daytime and nighttime numbness (7,18 VAS and 8,8 VAS respectively) compared to the ones without night pain (5,58 VAS and 5,3 VAS respectively). The level of night pain decreased to a minimal level after 1 week in all groups (1,36 VAS in group 1, 1,69 VAS in group 2 and 1,72 VAS in group 3). By the third month the night pain practically disappeared in all groups (1,32 VAS in group 1, 1,31 VAS in group 2 and 1,67 VAS in group 3). 3,6 VAS daytime numbness remained for group 3 which was significantly higher than the other groups (1,69 VAS in group 1 and 2,23 VAS in group 2). The overall satisfaction by this time was 8,45 VAS in group 1, 8,8 VAS in group 2 and 8,66 VAS in group 3.
Discussion: Our hypothesis failed as no significant difference was found in the satisfaction levels of the patients with and without night pain before surgery.
