A complication of the buried suture

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Surgical Complications

Background:

• Digital extensor tendon injuries require precise surgical repair to restore function.
• The central slip of the extensor mechanism is crucial for proper finger extension.
• Suture techniques aim for secure fixation while minimizing tissue reaction.

Observation:

• A patient developed an erosive lesion of the proximal interphalangeal joint following repair of the central slip of a digital extensor.
• The complication was directly associated with a buried suture material used during the surgical procedure.
• The lesion specifically affected the proximal interphalangeal joint of the long finger.

Findings:

• The buried suture acted as a nidus for an erosive process affecting the joint cartilage and bone.
• This represents a previously undocumented complication of extensor tendon central slip repair.
• Histopathological examination would be required to confirm the exact mechanism of erosion.

Implications:

• Surgeons should be aware of this rare but potentially destructive complication.
• Consideration of suture material and placement is critical in extensor tendon surgery.
• Further research may be needed to elucidate the pathogenesis and preventative strategies for suture-induced joint erosion.
