Background: Flexor tendon lacerations in the fingers are challenging injuries that can be repaired using the wide-awake local anesthesia no tourniquet (WALANT) technique or under traditional anesthesia (TA). The purpose of our study was to compare the functional outcomes and complication rates of patients undergoing flexor tendon repair under WALANT versus TA. Methods: All patients who underwent a primary flexor tendon repair in zone I and II without tendon graft for closed avulsions or open lacerations between 2015 and 2019 were identified. Electronic medical records were reviewed to record and compare patient demographics, range of motion, functional outcomes, complications, and reoperations. Results: Sixty-five zone I (N = 21) or II (N = 44) flexor tendon repairs were included in the final analysis: 23 WALANT and 42 TA. There were no statistical differences in mean age, length of follow-up, proportion of injured digits, or zone of injury between the groups. The final Quick Disabilities of the Arm, Shoulder, and Hand score in the WALANT group was 17.2 (SD: 14.4) versus 23.3 (SD: 18.5) in the TA group. There were no statistical differences between the groups with any final range of motion (ROM) parameters, grip strength, or Visual Analog Scale pain scores at the final follow-up. The WALANT group was found to have a slightly higher reoperation rate (26.1% vs 7.1%; P = .034) than the TA group. Conclusions: This study represents one of the first clinical studies reporting outcomes of flexor tendon repairs performed under WALANT. Overall, we found no difference in rupture rates, ROM, and functional outcomes following zone I and II flexor tendon repairs when performed under WALANT versus TA.

IntroductionPurpose: The study was conducted to investigate the influence of pulsed magnetic field therapy on hand function, grip and pinch grip strength in post flexor tendon repair patients.Material and methodsMethods: Fifty male patients with flexor tendon repair took part in this research, with ages ranging from 25 to 50 years. They were assigned randomly into two groups: Group A (experimental) received pulsed magnetic therapy together with exercise, whereas Group B (control) received only exercise. Evaluation of hand grip strength with Jamar hydraulic hand dynamometer, pinch strength with Baseline pinch gauge and hand function with Michigan Hand Outcomes Questionnaire, all measurements were made before and after the treatment. They were received 16 sessions for 8 weeks (2 sessions/week).ResultsResults: 2 x2 mixed design MANOVA revealed that no significant difference between both groups pre- treatment and post treatment in MHOQ total, function, aesthetic (p>0.05) and in hand grip strength while there was a significant difference across groups after treatment in the strength of pinch grip, MHOQ ADL, pain and satisfaction p <0.05), there was also a significant difference between pre- and post-treatment within groups in all outcome measures. (p <0.05).ConclusionsConclusion: PMF increases the efficiency of physical therapy treatment and it also increases the strength of both hand grip and pinches grip in patients after flexor tendon repair in zone II.

This human cadaver study investigated whether flexor tendon repairs performed with round-bodied needles had a higher risk of pull-out compared with those performed with cutting needles. Forty human cadaver tendons were repaired (20 with each type of needle), subjected to tensile traction testing and evaluated by failure load and mode of failure. The average failure load was 50 N (SD 13 N) for tendons repaired with round-bodied needles, compared with 49 N (SD 16 N) for tendons repaired with cutting needles. Round-bodied needles resulted in more suture pull-out (18 out of 20 tendons) than cutting needles (6 out of 20 tendons). We found no differences in failure load, but significant differences in the mode of failure between round-bodied and cutting needles when used for cadaveric flexor tendon repair.

The current clinical methods of flexor tendon repair are remarkably different from those used 20 years ago. This article starts with a review of the current methods, followed by presentation of past experience and current status of six eminent hand surgery units from four continents/regions. Many units are using, or are moving toward using, the recent strong (multi-strand) core suture method together with a simpler peripheral suture. Venting of the critical pulleys over less than 2 cm length is safe and favours functional recovery. These repair and recent motion protocols lead to remarkably more reliable repairs, with over 80% good or excellent outcomes achieved rather consistently after Zone 2 repair along with infrequent need of tenolysis. Despite slight variations in repair methods, they all consider general principles and should be followed. Outcomes of Zone 2 repairs are not dissimilar to those in other zones with very low to zero incidence of rupture.
