Nail Bed Injury clinical trials

Eponychial Stent Study

The study design is a prospective, randomized, controlled trial evaluating the cosmetic and functional outcomes of nail bed repairs with and without eponychial stents. Patients presenting to a single institution with a finger tip injury requiring a nail bed repair will be initially evaluated in the emergency department. The purpose of the study will be explained to the patient, and informed consent for participation will be obtained. Patients will be randomly assigned to either the eponychial stent or no eponychial stent group based on the last digit of their assigned medical record number. Even-numbered patients will be randomized to the stent group and odd-numbered patients will be randomized to the no stent group. Demographic data will be obtained and recorded (age, gender, hand dominance, mechanism of injury, and past medical history). All patients will undergo a thorough clinical exam under digital nerve block followed by removal of the nail plate and thorough irrigation and debridement of devitalized tissue. The nail bed repair will be performed with 6-0 chromic suture material. After the nail bed repair, a stent (native nail, suture container foil, or nonadherent gauze) will or will not secured under the eponychial fold with suture depending on randomization. Laceration characteristic and time required to perform the procedure will be recorded. A nonadherent sterile dressing will be applied to the digit, and each patient will be discharged with a 5-day course of cephalexin for prophylaxis against infection. Follow-up evaluation will occur at 1 week, 1 month, 3 months, and 6 months. A each follow-up visit, patient-perceived functional outcome, cosmetic outcome, and level of pain will be assessed using a 10-point analog scale. Cosmetic results will also be evaluated by the examining physician using a validated physician-based outcome tool.
