Masquelet technique for Mx of acute osteomyelitis of PIP joi
The present case has been published in the International Journal of Surgery Case Reports. 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.

The patient was a 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. The angled joint resulting from this technique created a relatively normal permanently bent PIP joint.

Lessons to be learned:-
- 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.

- The authors were able to reconstruct a more anatomical, bent PIP joint, and the fixed angle of the PIP joint at 40 degrees of flexion using Masquelet technique.
