Rethinking the Need for Nail Plate Removal: A Comparison of the Risks Between Standard Nail Bed Repair and...

Nail bed injuries are commonly treated with nail plate removal and repair due to concern for future nail deformity. There is controversy whether this is necessary. We compared the outcomes for adult patients with simple nail bed lacerations who underwent either formal nail bed repair or nonoperative management.

A retrospective cohort study was performed of adult patients with nail bed lacerations from 2012 to 2019. Nail bed lacerations were diagnosed in patients with fingertip injuries resulting in subungual hematoma greater than 50% or in any subungual hematoma in the setting of a distal phalanx fracture. All patients included had an intact nail plate. Patients were treated with nail bed laceration repair or nonoperatively without nail plate removal. The primary outcome was the development of a nail deformity. Secondary outcomes included infection, fracture nonunion, and patient-reported functional outcomes using the quick Disabilities of the Arm, Shoulder and Hand score.

Thirty-eight patients with nail bed lacerations were treated nonoperatively, and 40 patients were treated with nail bed repair. The average follow-up time was 4.5 weeks in the office. In addition, 1-year evaluation of patients was performed through telephone interview. The patients in the nonoperative group exhibited no statistically significant difference in the calculated risk for nail deformities compared with the nail bed repair group (13% vs 23%, relative risk = 0.58, P = 0.40, 95% confidence interval = 0.42-1.25). There were no significant differences in secondary outcomes or quick Disabilities of the Arm, Shoulder and Hand scores between groups.

The authors observed no meaningful difference in the rate of nail deformities in adult patients who underwent nail bed repair compared with those managed nonoperatively.
