Appearance Outcomes of Repositioned Native Nail Plate as a Free Graft and Artificial Nail Plate in the Reconstruction of the Fingertip Injuries.

PURPOSE: The aim of this study was to evaluate the cosmetic outcomes of native nail plate (NP) replacement as a free graft and using an artificial NP in reconstruction of the fingertip injuries.

METHODS

Two prospective cohorts of patients with fingertip injuries and avulsed NPs were evaluated. In group 1 (54 patients with 61 fingertip injuries), the native NP was available and suitable for placement under the proximal nail fold. In group 2 (31 patients with 32 fingertip injuries), the native NP was either lost or highly damaged and it was not suitable for use. In this group, an artificial NP was used. The final cosmetic outcomes of regrown NPs were evaluated at a minimum of 4 months after surgery using the Oxford Finger Nail Appearance Score.

RESULTS

"Trapped in a door" was the most common cause of injury in pediatric patients, whereas work-related injuries were the most common cause of injury in adults. The difference between the mean appearance scores of the two groups favored group 1 (native NP). There was a negative correlation between the patient age and appearance scores, irrespective of the treatment group. The presence of a distal phalanx fracture adversely affected the appearance scores.

CONCLUSIONS

Replacing the native NP for splinting in fingertip injuries is advantageous. Fingertip injuries in pediatric patients and fingertip injuries without distal phalanx fractures achieved better cosmesis scores.

TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.
