Summary
Accessory soleus muscle variations show diverse insertions, impacting surgical planning. Detailed radiologic imaging is crucial for accurate pre-operative assessment of these anatomical anomalies.
Area of Science:
- Anatomy
- Radiology
- Orthopedic Surgery
Background:
- The accessory soleus muscle is an uncommon anatomical variant.
- Understanding its variations is essential for diagnosing foot and ankle pain and planning surgical interventions.
Purpose of the Study:
- To present four cases of accessory soleus muscle.
- To detail the anatomical course and insertion variations using advanced imaging techniques.
- To highlight the clinical significance of these variations in operative treatment planning.
Main Methods:
- Soft tissue radiography was utilized to visualize the accessory soleus muscle.
- Computed tomography (CT) provided detailed cross-sectional imaging of the muscle's course and insertion.
- Four distinct cases were analyzed to identify insertion patterns.
Main Results:
- Four different insertion types of the accessory soleus muscle were identified:
- 1. Insertion along the tendon of Achilles.
- 2. Fleshy insertion to the superior calcaneus.
- 3. Insertion via a separate tendon to the superior calcaneus.
- 4. Fleshy insertion to the medial calcaneus.
Conclusions:
- Accessory soleus muscle exhibits significant anatomical variability in its insertion.
- Accurate pre-operative radiological examination is vital for surgical planning.
- Awareness of these variations can prevent intraoperative complications and improve patient outcomes.
