Clinical Analysis of a Novel Flexor Tendon Repair Technique

The purpose of the research study is to determine the efficacy and efficiency of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care, L-O (Lew-Omar), suture repair technique. The investigators will also determine if there are similar or different rates of complications and failures via both objective and subjective measures.

About this study

To determine the tendon failure/rupture rate of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care suture repair technique. The investigators will determine if there are similar or different rates of complications and failures (both intraoperatively and at 2-week, 6-week, 3-month, and 6-month post-operative intervals).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Study subjects aged 22 and older.
  • Subjects who sustained a Zone 2-5 flexor tendon lacerations

Exclusion criteria

  • Subjects under the age of 22 at the time of consent
  • Subjects who sustained a Zone 1 flexor tendon injury
  • Subjects who have had previous surgical procedures on the injured upper extremity.
  • Subjects who have metal allergies
  • Ischemia, blood supply compromise, and/or inadequate wound coverage
  • Prior or current infections at or near the implant site
  • Conditions which tend to limit the patient's ability or willingness to restrict activities or follow directions during the healing period
  • Foreign-body sensitivity
  • The physical contact of the CoNextions TR Tendon Repair System with metal implants made of anything other than the implant grade of stainless steel, such as titanium, titanium alloys, cobalt chromium, or other dissimilar metals
  • Surgical procedures other than for the following indication: digital flexor tendons, digital extensor tendons proximal to the metacarpophalangeal joints (Zones 6-8)
  • Tendon size or surgical site access outside of specified range (Tendon Width (3.0-9.0 mm), Tendon Thickness (1.5-4.0 mm), Minimum Surgical Site Access (20 mm [10mm/side]) for the CoNextions TR Tendon Repair System

Treatment and study plan

Primary outcomes

  1. To determine the tendon failure/rupture rate of two tendon repair techniques: the CoNextions tendon repair device vs a standard of care suture repair technique. Also to determine if there are similar or different rates of complications and failures

    Time frame: From enrollment to end of postoperative follow up at 6-months.

Secondary outcomes

  1. Time to Repair

    Time frame: From enrollment to end of postoperative follow up at 6-months

    The units measured will be minutes/seconds for repair

  2. Visual Analog Pain Scale

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Visual number scale to rate pain

  3. Quick DASH Form

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Assessment of symptoms and ability to perform certain activities.

  4. Patient Satisfaction Questionnaire

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Assessment of perceptions of technical quality, interpersonal manner, communication, financial aspects, time spent with the doctor, accessibility, and convenience, as well as overall general satisfaction.

  5. Grip/Strength Assessment

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Measured using a hand-held dynamometer in units of pounds/kilograms

  6. Range of Motion Assessment

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Measured using a goniometer and recorded in degrees.

  7. Surgical Time

    Time frame: From enrollment to end of postoperative follow up at 6-months

    Total surgical time recorded in minutes.
