Posterior Cord Injury

Losses

 Motor Function

 Subscapularis Nerve function - Subscapularis and Teres Major 

Thoracodorsal Nerve - Latissimus Dorsi 

Axillary Nerve - Deltoid and Teres Minor 

Radial Nerve - Extensor of Elbow , Wrist fingers 



Sensory loss over Deltoid 



Functions affected 

 Shoulder IR / Abduction , Extension of elbow , Wrist and Fingers 



Improvement in triceps without deltoid suggests Axillary Nerve entrapment in Quadrangular Space.
