anatomy

The Biceps muscle (Muscle biceps brachii) called biceps for short belongs to the upper arm flexor muscles on the front of the upper arm. It is a two-jointed muscle that is connected to the Shoulder joint and the Elbow joint pulls.

The biceps muscle / biceps has two sinewy origins:

  • The long biceps tendon has its origin at the upper edge of the shoulder socket (glenoid). This origin is also known as the biceps tendon anchor. From its origin it runs through that Shoulder joint to the head of the humerus, where it continues in a bony groove (sulcus bicipitalis) towards the muscle belly. On the front of the shoulder, on the head of the humerus, the long biceps tendon can be easily felt in its groove.
  • The short biceps tendon of the biceps muscle / biceps has its origin in a continuation of the shoulder blade, the coracoid. The tendon runs diagonally downwards to the common muscle belly on the front of the upper arm.

The biceps muscle / biceps make up the majority of the external structure of the front upper arm.

It runs with a tendon Biceps muscle / biceps out. The tendon attaches to a stable roughness of the spoke bone (radius / Radial tuberosity). The tendon is very thick and stable. An extensive secondary tendon radiates into the muscular forearm covering (fascia).

function

The biceps muscle / biceps has functions for moving the shoulder and shoulder muscles Elbow joint.

With its two origins, the biceps muscle / biceps acts as a lateral lifter (long biceps tendon = abductor), spreader (short biceps tendon = adductor), inner turner and forelevator (both) of the upper arm.

In the area of ​​the elbow joint, the biceps muscle / biceps functions as the most powerful forearm flexor and inner turner of the forearm (supinator = turn the palm of the hand towards the ceiling).

Through targeted examination techniques, the biceps muscle / biceps can be tensed to such an extent that characteristic pain occurs in the event of an injury.

Diseases

Biceps tendon tear

The long biceps tendon is particularly prone to injuries to the biceps muscle / biceps. Chronic damage to the shoulder joint and instability in the upper arm groove can lead to inflammation (Tendovaginitis bicipitis) up to the complete Biceps tendon tear (biceps tendon rupture) come. Even the layperson recognizes this impressively Torn long biceps tendon on the slipped down muscle belly at the level of the lower upper arm due to the missing upper suspension.

A Torn short biceps tendon is very rare. Rarely, if occasionally, the strong biceps tendon attachment at the level of the elbow joint also tears. While a tear in the long biceps tendon does not necessarily have to be operated on and is functionally well tolerated, a tear in the attachment of the biceps tendon is associated with a considerable loss of function, which is why surgical intervention is necessary.

SLAP - lesion

Painful injuries to the biceps tendon anchor are difficult to diagnose (SLAP - lesion) difficult to grasp on physical exam and even in a Magnetic spin scan (MRI) of the shoulder are often overlooked.

Appointment with ?

I would be happy to advise you!

Who am I?
My name is dr. Nicolas Gumpert. I am a specialist in orthopedics and the founder of and work as an orthopedist at Lumedis.
Various television programs and print media report regularly about my work. On HR television you can see me live every 6 weeks on "Hallo Hessen".
But now enough is indicated ;-)

In order to be able to treat successfully in orthopedics, a thorough examination, diagnosis and a medical history are required.
In our very economic world in particular, there is not enough time to thoroughly grasp the complex diseases of orthopedics and thus initiate targeted treatment.
I don't want to join the ranks of "quick knife pullers".
The aim of all treatment is treatment without surgery.

Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.

You will find me:

  • Lumedis - orthopedic surgeons
    Kaiserstrasse 14
    60311 Frankfurt am Main

You can make an appointment here.
Unfortunately, it is currently only possible to make an appointment with private health insurers. I hope for your understanding!
