Despite extensive clinical experience in treating cubital tunnel syndrome, optimal surgical management remains controversial. A meta-analysis of 30 studies with accurate preoperative and postoperative staging was undertaken. Patients were staged preoperatively into minimum, moderate, and severe groups on the basis of clinical presentation. Treatment modalities included nonoperative management, surgical decompression, medial epicondylectomy, anterior subcutaneous transposition, and anterior submuscular transposition. Statistical analysis using a standard SAS database with analysis of variance and chi-square tests was used to assess the efficacy of each therapeutic modality. For minimum-staged patients, all modalities produced similar degrees of satisfaction. However, total relief occurred most after medial epicondylectomy and least after anterior subcutaneous transposition. Patients treated nonoperatively had the highest rate of recurrence. For moderate-staged patients, submuscular transposition was most efficacious, whereas patients with nonoperative management fared the worst. Finally, for severe-staged patients, current therapeutic modalities were not consistently effective, with medial epicondylectomy producing the poorest operative result. This article reveals statistically significant differences in outcomes among therapeutic modalities, which may assist in treatment planning; it introduces standardized methods to aid in determining, analyzing, and communicating treatment outcomes.
Pincer-nail syndrome has been described as distortion in the shape of the nails with excessive transverse curvature of the plate that increases from proximal to distal, leading to pinching and loss of soft tissue in the affected digit, resulting in severe pain. Many treatments have been recommended, but an effective long-term method that preserves the nail matrix has not been described. A method of dermal grafting under the nail matrix is described, and the results of treatment of six digits are reported. Five women and one man with an average age of 52 were treated. The affected digit was the thumb in four patients and the great toe in two patients. Follow-up averaged 25 1/2 months. The results were good in all cases with only one side of one nail remaining slightly curved. Pain was relieved in all cases, and complete adherence of the new nail plate occurred. Dermal grafting seems to provide excellent long-term treatment of the pincer-nail deformity with preservation of the nail matrix.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
