Talofibular Bony Impingement in the Ankle.

Area of Science:

• Orthopedics
• Sports Medicine
• Anatomy

Background:

• Talofibular bony impingement is a previously unreported condition.
• It is challenging to diagnose using standard plain radiography.
• This condition may be responsible for restricted ankle dorsiflexion.

Purpose of the Study:

• To evaluate talofibular bony impingement as a distinct cause of limited ankle dorsiflexion.
• To investigate the diagnostic challenges and clinical impact of this condition.

Main Methods:

• A comparative study included 20 patients with talofibular impingement and 19 controls.
• Intraoperative visualization confirmed impingement presence.
• Dorsiflexion was measured pre- and post-excision of spurs.
• Radiographic and CT findings were analyzed.

Main Results:

• Ankle dorsiflexion increased by an average of 7.9 degrees after spur removal.
• Weight-bearing radiographs showed reduced fibula-talar distance in the impingement group.
• CT scans revealed more talar bone protrusion in patients with impingement.
• Overall clinical assessments demonstrated improvement.

Conclusions:

• Talofibular impingement is identified as a cause of limited ankle dorsiflexion.
• Intraoperative findings confirmed the diagnosis.
• Surgical intervention can alleviate symptoms and improve function.
