Patient-Reported Outcome Following Ulnotriquetral Ligament Split Tear Repair

While the clinical presentation and mechanism of injury of ulnotriquetral (UT) ligament split tear had been well described, there has been no other studies that has reported on the outcome of a UT ligament repair. This study aims to look at the patient-reported outcomes following UT ligament split tear repair.

18 wrists (13 right and 5 left) in 17 patients (12 males and 5 females, mean age 25.0 ± 8.4 years, range 16-50 years) who had UT ligament split tear and undergone surgical repair between November 2007 and December 2013 were retrospectively analysed. Patient-reported outcome of resolution of pain, and objective measurements such as improvement in grip strength and range of movement of the wrist were recorded. Patients were followed up until the pain was completely resolved or the last documented consultation. The mean follow-up duration was 16.2 months.

94% reported improvements post-surgery, of which 63% reported complete resolution of pain. 6% reported no improvement in pain post-operatively. No patient reported worsening of pain after the surgery. There was significant improvement in grip strength from a mean of 23.5 kg to 27.1 kg. There was no significant change in range of motion of the wrist.

The majority of patients reported resolution or improvement of pain after surgical repair. In addition, there was statistically significant improvement in grip strength recorded.
