“…Pincer nail was first reported in 1950 by Frost1, using the term "incurvated nail". Cornelius and Shelley2 introduced the term "pincer nail" in 1968. Although ingrown nails are confused with pincer nails, the pincer nail is differentiated from ingrown nails by its abnormal shape of decreasing width and increasing height of the nail plate; the ingrown nail has a normal shape3.…”

BackgroundPincer nail is a nail deformity characterized by transverse overcurvature of the nail plate. Pincer nail can affect a patient's quality of life due to its chronic, recurrent course; however, there have been no clinical studies on the pincer nail condition in Korean patients.ObjectiveThe purpose of this study was to characterize the clinical findings and treatment of pincer nail. In addition, possible etiological factors were considered, and treatment efficacy was evaluated.MethodsThe medical records and clinical photographs of 35 patients (12 males, 23 females) who were diagnosed with pincer nail between August 1, 2005 and July 31, 2009 were studied.ResultsPatient age ranged from 10 to 77 (52.09±17.26) years, and there was a predominance of female (23 out of 35 patients, F:M=2:1). The mean duration of the disorder was 7.45 years (range 0.25~40); 85% had pincer nail for at least 1 year. In addition, 40% had a history of previous treatment and recurrence. There were 82.8% patients with the common type of pincer nails. The most commonly involved nails were both great toenails. Among 35 patients, nail grinding was started in 30 patients, and 25 patients showed clinical improvement with nail grinding. The width index increased and the height index decreased after treatment. The mean follow up period was 8.42 months (range 1~27), and 7 patients showed recurrence after 8.8 months (range 2~20). Among 35 patients, 5 patients were treated with nail extraction with matricectomy, and the symptoms resolved immediately. The mean follow up period was 7.6 months (range 0~19), and recurrence was not observed. Onychomycosis was also present in 37.1% of patients, and itraconazole pulse therapy for 3 months was added.ConclusionThe results of this study demonstrate the clinical features of pincer nail in Korean patients. The findings show that the common type of pincer nail was most common, and nail grinding as a conservative treatment greatly improved pincer nails despite a risk of recurrence. When onychomycosis was also present, oral antifungal therapy added to nail grinding resulted in a more rapid change in nail thickness and clinical improvement.

Although pincer nail deformity (PND) treatment is time consuming independent of whether it is based on surgical or conservative procedures, long lasting beneficial results are found only after surgical intervention. Typically destruction of the lateral matrix horns either surgically or by phenol cauterization or even ablation of the matrix is performed. In the past these procedures mainly aimed at relief from pain; however, currently more patients ask for the preservation of the nail unit and a good cosmetic outcome. Today reconstructive results that meet the patient expectations are available. An adapted novel surgical method which will preserve the matrix horns while correcting the shape of the phalanx and preventing renewed adhesion of the nail bed to the phalanx is presented. Therefore the restoration of a normal width-to-length ratio of the nail plate with a cosmetically appealing result becomes possible. Surgical steps in an affected right toenail are presented.

“…3). 40 Ingrown nails resemble pincer nails as they are characterized by a sharp irregular nail edge that involves the distal corners of the nails; they are usually due to improper trimming. However, while ingrown nail may be confused with pincer nail and at the clinical level the two often associate with each other, ingrown nail is generally a relatively symptomatically derived term, while pincer nail is a more morphologically derived term.…”

Summary:Mechanobiology is an emerging field of science that focuses on the way physical forces and changes in cell or tissue mechanics contribute to development, physiology, and disease. As nails are always exposed to physical stimulation, mechanical forces may have a particularly pronounced effect on nail configuration and could be involved in the development of nail deformities. However, the role of mechanobiology in nail configuration and deformities has rarely been assessed. This review describes what is currently understood regarding the effect of mechanical force on nail configuration and deformities. On the basis of these observations, we hypothesize that nails have an automatic curvature function that allows them to adapt to the daily upward mechanical forces. Under normal conditions, the upward daily mechanical force and the automatic curvature force are well balanced. However, an imbalance between these 2 forces may cause nail deformation. For example, pincer nails may be caused by the absence of upward mechanical forces or a genetic propensity increase in the automatic curvature force, whereas koilonychias may occur when the upward mechanical force exceeds the automatic curvature force, thereby causing the nail to curve outward. This hypothesis is a new concept that could aid the development of innovative methods to prevent and treat nail deformities.
