Nail Bed Injury Repair: Nail Plate Replacement Versus Non-replacement.

Background

Although nail bed injuries are common, there is no consensus on the proper course of treatment in regard to nail plate replacement. Nail plate replacement risks infection and injury of the germinal matrix. It is our hypothesis that functional and cosmetic outcomes of the nail will not differ by nail plate replacement following nail bed repair.

Methods

This is a single institution, prospective, randomized control study comparing nail plate replacement versus non-replacement in patients undergoing nail bed repair. Primary outcome included nail growth and cosmesis using the Zook classification system. Secondary outcomes were pain, functional limitation, and patient satisfaction. Statistical significance was set at

Results

Fifty patients were enrolled, 26 (52%) randomized to the non-replacement group and 24 (48%) to the replacement group. All patients who followed up had nail growth by 4 months after nail bed repair (N = 28). In the non-replacement group 4 patients continued to have pain in the affected nail bed compared with 2 patients in the replacement group (

Conclusions

Statistical and clinical differences were not identified in regard to cosmesis, pain, functional use of the hand, or patient satisfaction. There are established risks involved in nail plate replacement such as infection and injury to the germinal matrix. If outcomes are not different based on nail plate replacement following nail bed repair, non- replacement may be the preferable treatment option so as to avoid these complications.
