Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be assigned using a 1:1 randomization scheme to receive either the investigational device or a suture repair for the surgical treatment of their tendon lacerations.
Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Outcome Assessors
Participants and the Occupational Therapist performing the majority of the outcome assessments will be masked to the treatment until the 12 week post-operative visit.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CoNextions TR Implant

Operative repair of Zone 2 FDP tendon lacerations will be performed using the CoNextions TR Implant System

Group Type EXPERIMENTAL

Operative repair of Zone 2 FDP tendon lacerations

Intervention Type PROCEDURE

Zone 2 tendon laceration(s) will be surgically repaired either using the experimental device or the active comparator

CoNextions TR Implant System

Intervention Type DEVICE

The CoNextions TR Implant System will be used to repair Zone 2 FDP tendon laceration(s).

Suture Repair

Operative repair of Zone 2 FDP tendon lacerations will be performed using a 4-strand locked cruciate repair utilizing either 3.0 or 4.0 prolene suture

Group Type ACTIVE_COMPARATOR

Operative repair of Zone 2 FDP tendon lacerations

Intervention Type PROCEDURE

Zone 2 tendon laceration(s) will be surgically repaired either using the experimental device or the active comparator

4-strand locked cruciate repair

Intervention Type DEVICE

A 4-strand locked cruciate repair utilizing either 3.0 or 4.0 prolene suture will be used to repair Zone 2 FDP tendon laceration(s).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. At least 18 years of age
2. Willing and able to provide a signed and dated informed consent form
3. Stated willingness to comply with all study procedures
4. Available for the duration of the study
5. Have one or two fully lacerated digital FDP tendon(s), with or without a concomitant injury of the flexor digitorum superficialis, in Zone 2 of the index, middle, ring, or small finger
6. Tendon laceration occurred within the previous 14 days

Exclusion Criteria

1. Pregnant or planning to become pregnant during the follow-up period
2. Autoimmune disorder(s)
3. Type 1 diabetes mellitus or clinical history of poorly controlled Type 2 diabetes mellitus
4. Lack of proper cutaneous coverage at repair site
5. Concomitant fracture
6. Amputated digit(s)
7. Arthritis of the hand
8. Prior hand trauma with residual impact to function
9. Congenital hand defect
10. Conditions that would affect comparative measurements in the uninjured hand
11. Tendon laceration caused by a crush injury
12. Prior sensory impairment in digits of either hand. Note: Participants with nerve injuries associated with the trauma causing the current flexor tendon injury are eligible for enrollment
13. Vascular injuries that require revascularisation procedures
14. Ischemia and/or blood supply compromise
15. Prior or current infections at or near the intended implant site
16. Active sepsis, MRSA, or other conditions that may prevent healing
17. History of foreign-body sensitivity to 316 L Stainless Steel or UHMWPE
18. Implantation of CoNextionsTR Implant would result in physical contact with other metal implants made of material other than implant grade stainless steel such as titanium, titanium alloys, cobalt chromium, or other dissimilar metals
19. Any condition(s) which, in the opinion of the investigator, may impact the participant's ability to properly follow-up or otherwise be at-risk for following protocol instructions
20. Currently participating in another clinical/device trial

The following criteria, determined during the surgical procedure, will also cause an individual to be excluded from the study:
21. Surgical site access less than 20 mm in total or less than 10 mm on either side of intended implant site
22. Injured tendon is outside of the width range (3.0-7.0 mm) and thickness range (1.5-4.0 mm) specified for the CoNextionsTR Implant System.
