Sulcus ulnaris syndrome

The Sulcus ulnaris syndrome belongs to the nerve bottleneck syndromes. These occur when a nerve is constricted in its course by surrounding structures and thus becomes irritated. At the inner elbow, the ulnar nerve runs along the back in a bone groove.

There, the nerve can very quickly become constricted due to the generally already relatively tight conditions, especially as a result of fractures or other inadequately healed injuries. This leads to pain along the entire nerve as well as to sensory disturbances in the target area on the back of the hand and in the area of the ring finger and little finger. Furthermore, it can lead to a reduction in strength and a limitation of the bending ability of these fingers.

This is particularly noticeable in the closure of the fist, which can then only be performed incompletely. With a longer course and insufficient treatment, the disturbed supply of the musculature by the nerve can lead to a significant decrease of the nerve. This muscular atrophy becomes visible by a distinct groove formation at the ball of the little finger.

Elbow Arthrosis

As in all joints of the body, arthrosis can also occur in the elbow. This can be caused by any damage to the joint cartilage. Frequent causes are incorrect loading, injuries, inflammation or malposition of the joint.

However, a defined cause of arthrosis cannot be determined in all cases. In the course of the disease, there are increasingly active and passive movement restrictions and sometimes noticeable friction in the joint, so-called crepitus. If the arthrosis is acutely activated, swelling and effusion formation at the elbow can also be observed.

Biceps tendon inflammation

The M. biceps brachii attaches via its tendon directly below the elbow joint to the spoke of the forearm. Inflammation of this tendon can therefore also lead to pain in the elbow region. As with all tendon inflammations, the cause is usually an overloading of the muscle and the associated tears of the tendon.

The inflammatory reaction is the body’s attempt to repair these tears. However, since tendons have a complex connective tissue framework, this is usually not completely successful. This results in scarring within the tendons.These scars in the tendon structure lead to a significant loss of extensibility and can thus lead to a reduction in muscle function over time.
