Time to removal of sutures from the palmar surface of the hand in dark-skinned patients: Results in a prospective cohort of 146 hands

Abstract

The objective of this study was to estimate the time to removal of a suture from the palmar surface of a dark-skinned adult hand. A descriptive and analytical study included a cohort of 146 patients, 57% male, with a mean age of 37 ± 14 years, covering a period of 10 years. The mean time to removal of sutures on the palmar surface of the dark-skinned adult hands was 21 ± 2 days. Complete epithelialization of the suture path was the clinical indication for the ideal day for removal. After removal, closure was total in 90% of cases (132 hands) and partial in 9% (14 hands). The day of suture removal was significantly (p = 0.006) related to wound healing (complete closure). Eighty-five percent of patients without complete wound closure at suture removal had history of use of skin-lightening products. Tobacco use significantly lengthened time to suture removal (p < 0.001). There was a correlation between patient age and time to suture removal. On multivariate analysis, three factors were predictive of suture removal later than day 21: being a manual worker (44% of patients) (p 0.006), suture location in a palmar fold area (<0.001) and the age of patient, the 41–50 years (p = 0.001) and >50 years (p < 0.001).
