In 12 limbs, we noticed that the branch of the PL muscle was long enough to reach the PIN, distal to the branches to the supinator muscle, free of tension even with the movements of the forearm and elbow (Figs.
The superficial interval between the extensor carpi radialis brevis and the extensor digitorum communis was incised and the supinator muscle belly was exposed (Figs.
Damage to the PI nerve has been usually reported in the dorsal approach, but its occurrence after volar approach indicates that, careful attention must be paid during supinator muscle dissection.14
In PIN palsy, a bulging mass due to chronic proliferative synovitis or acute/subacute synovial effusion of the elbow joint may cause compression of the PIN against the fibrous edge of the supinator muscle. (8) Therefore, close monitorization of the inflammation and the clinical picture of RA patients is crucial so as to prevent complications like PIN palsy.
The posterior interosseus nerve is a branch of the radial nerve just distal to the elbow joint and supplies the supinator muscle and extensors of the wrist and fingers.
On both ulnae, the crest that supports the supinator muscle (the muscle that turns the forearm when the elbow is straight) is pronounced.
However, we have been able to visualise it by placing the ultrasound probe at the proximal part of the posterolateral compartment of the forearm, 5 to 7 cm away from the elbow, exactly at the point where the nerve plunges into supinator muscle (Figure 1d).
The first PTM branch of the median nerve had enough length to be transferred to the AIN in 23 (76%) limbs, while they could reach the radial nerve branches to the ECRL, ERCB and PIN distal to branches for the supinator muscle in all members.
It demonstrated findings suggestive of posterior interosseus nerve injury and compression within the supinator muscle causing early muscle denervation (Figs.
The posterior interosseous nerve (PIN) branch is commonly entrapped in the supinator muscle at the radial tunnel, causing symptomotology similar to LE.
