Objectives/Interrogation: TFCC injuries significantly affect patients quality of life. Most of patients complains are concerned with high developed pain which unable performing the everyday living activities. Most recommended treatment is the arthroscopic treatment of the lesion. The aim of the study was to asses patients wrist flexors and extensors biomechanical parameters after TFCC operative treatment.

Methods: 28 patients (9 male and 19 female) with mean age 36 years were biomechanically tested on Biodex System 4 Pro device with isotonic protocol. Mean time of follow up was 5 years after the surgery. There were 15 patients after arthroscopic repair of TFCC Palmer 1B tear, 2 patients after TFCC Palmer 1A tear, 2 patients after TFCC Palmer 1D tear and 1 patient with TFCC Palmer 1A and 1B tears. Wrist flexors and extensors were tested in 3 trials (0,5 Nm/1 Nm/0,5 Nm) in which the patients performed sequentially 4 movements of wrist flexion and extension. Grip strength was measured with electronic dynamometer.

Results and Conclusions: There were no significant differences between wrist extensors and flexors biomechanical parameters in operated and healthy limb. The average functional ROM for the operated wrist was 117.58 degrees and 123.64 degrees for the healthy one. The average velocity of the wrist extensors was 225.96 deg/sec for the operated wrist and 221.14 deg/sec for the healthy one. The average velocity of the wrist flexors was 343.74 deg/sec for the operated wrist and 368.79 deg/sec for healthy one. Grip strength value was 32.07 kg for operated wrist and 33.58 kg for healthy one. Over 75% of patients were extremely satisfied with the operative results and only 2 patients had no improvement.

TFCC arthroscopic treatment enables almost full recovery of the injured hand and allows to achieve high values of wrist flexors and extensors muscles biomechanical parameters. Biomechanical evaluation of wrist function after surgery significantly expands our knowledge of the results of arthroscopic treatment of TFCC lesions.
