title: Osteonecrosis of Interphalangeal Joint of Thumb Two Months after Rattlesnake Bite.
abstract: This case report details the osteonecrosis of the interphalangeal (IP) joint of the thumb two months after a rattlesnake bite. It describes the clinical presentation, imaging studies, histological review, pathology review, and review of literature. Our patient was a fifty-one year-old male who obtained a poisonous snakebite to the thumb. While in the hospital for acute treatment, a blood blister was debrided. He was seen two weeks after discharge for further debridement of epidermolysis. Patient presented one month later with a hand x-ray demonstrating bony erosions, and a bone scan showing active changes in the IP joint of his right thumb. He was taken to the OR for further debridement and definitive diagnosis. Pathology results confirmed osteonecrosis with negative bone cultures. The clinical presentation, diagnosis, and operative management of osteonecrosis offer a unique challenge, especially in a patient presenting with osteonecrosis from a poisonous snakebite.
