A Technique for Wound Cavity Closure after Coccyx Resection in Experiment

Introduction. Closing the wound cavity after the coccyx resection in patients with posttraumatic coccygodynia remains an issue unresolved. Closing the wound cavity with local tissues often leads to the wound dehiscence due to excessive tension which in turn leads to suppuration and prolonged healing.This paper aims to assess experimentally the effectiveness of using ground autograft bone of the coccyx removed for the closure of the surgical wound.Materials and methods. In the animal experiment the coccyx resection was performed under a combined anaesthesia in six pigs (three in the study group and three in control). In the control group the wound edges were sutured to its floor. In the study group after the coccyx resection the ground bone mass made of the coccyx resected was implanted into the wound cavity.Results and discussion. In the control group the wound dehiscence was registered in all the animals. After the animals were taken out of the experiment it was established that in the study group a new consolidated bony conglomerate was formed without any pronounced inflammatory changes around the wound. In control the wound cavity healed with secondary intention.Conclusions. The study confirms the effectiveness of using ground autograft bone for the closure of the wound cavity.
