Charcot arthropathy after acetabular fracture

Area of Science:

• Orthopedic Surgery
• Diabetology
• Radiology

Background:

• Acetabular fractures are severe injuries requiring surgical intervention.
• Diabetes mellitus is a common comorbidity affecting bone health and healing.
• Neuropathic arthropathy, like Charcot joint, is a known complication in diabetes.

Observation:

• Three middle-aged diabetic patients with acetabular fractures underwent open reduction and internal fixation.
• Following surgery, all patients exhibited rapid femoral head dissolution.
• The dissolution presented with minimal discomfort, characteristic of Charcot arthropathy.

Findings:

• The observed femoral head dissolution mimicked Charcot changes but occurred in the absence of other neuropathic arthropathy signs.
• High-energy trauma appears to be a significant factor in precipitating these Charcot-like changes in diabetic patients.
• The rapid joint destruction suggests a potential link between traumatic injury and diabetic bone metabolism.

Implications:

• This case series highlights a potential, previously under-recognized complication of acetabular fractures in diabetic individuals.
• Clinicians should consider the possibility of rapid joint degeneration in diabetic patients post-trauma, even without pre-existing neuropathy.
• Further research is warranted to elucidate the pathophysiology and optimal management strategies for this condition.
