Restricted thumb extension due to flexor pollicis longus tendon adhesion following volar plate fixation with bone substitute use for distal radius fracture: A case report and literature review

When using bone graft substitutes containing demineralized bone matrix or bone morphogenetic proteins, measures should be taken to prevent leakage into adjacent soft tissues, particularly in regions containing multiple tendons. In addition, any leaked bone graft substitute should be removed using techniques such as irrigation at the surgical site.
