Masquelet technique for the treatment of acute osteomyelitis of the PIP joint caused by clenched-fist human bite injury: A case report

摘要

Introduction The Masquelet technique is a well-known and efficient procedure for lower limb soft tissue reconstruction after severe osteomyelitis requiring bone excision. However, this technique is rarely used in the hand. Presentation of case The patient was 38-year-old man. We used this technique to reconstruct a proximal interphalangeal (PIP) joint osteochondral defect after osteomyelitis caused by clenched-fist human bite injury. The pathogen was Prevotella intermedia , which is an anaerobic pathogenic bacterium involved in periodontal infections and is a black-pigmented periodontal pathogen. Following completion of the Masquelet method, the bone remodeled at an angle at the PIP joint. Discussion Prevotella intermedia is known as Bacteroides melaninogenicus subsp. intermedius . When the infection site is black-pigmented, this pathogen is highly suspected. The Masquelet technique is rarely used in the hand, and when used, it has been in a straight fashion in the hand. We were able to reconstruct a more anatomical, bent PIP joint, and the fixed angle of the PIP joint at 40° of flexion using Masquelet technique. Conclusion The angled joint resulting from this technique created a relatively normal permanently bent PIP joint.
