From the Research
Sutures on the palmar surface of the hand should remain in place for approximately 21 days before removal, as this allows for complete epithelialization of the suture path and optimal wound healing. This recommendation is based on the most recent and highest quality study available, which found that the mean time to removal of sutures on the palmar surface of dark-skinned adult hands was 21 ± 2 days 1. The study also found that complete epithelialization of the suture path was the clinical indication for the ideal day for removal, and that 90% of cases had total closure after removal.
The palm of the hand is a unique area that experiences significant tension and movement during daily activities, which can stress the healing wound. As a result, the skin on the palm takes longer to heal properly compared to other areas of the body. During the healing period, it is essential to keep the wound clean and dry, changing any bandages as directed by a healthcare provider. Patients should also watch for signs of infection, such as increasing redness, warmth, swelling, pus, or fever, which would require prompt medical attention.
Some studies have compared different suture materials and techniques for wound closure on the hand, but these studies have limitations and are not directly relevant to the question of suture retention duration 2, 3, 4, 5. For example, a study comparing absorbable and non-absorbable sutures for skin closure after carpal tunnel decompression surgery found that the use of absorbable sutures eliminated the need for suture removal, but the study did not provide clear guidance on the optimal duration of suture retention 3. Another study comparing interrupted mattress closure with running subcuticular closure with vicryl rapide suture found no significant difference in postoperative pain, functional outcomes, or incidence of infection between the two groups, but again did not address the question of suture retention duration 5.
In clinical practice, the specific timing for suture removal may vary based on the depth and location of the wound, the patient's overall health, and how well the wound is healing. However, based on the available evidence, a suture retention duration of approximately 21 days is recommended for sutures on the palmar surface of the hand 1. This allows for optimal wound healing and minimizes the risk of complications. Patients should always follow their healthcare provider's personalized instructions for wound care and suture removal.
