What passes through bicipital groove of humerus?
The bicipital groove (intertubercular groove, sulcus intertubercularis) is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle. It allows for the long tendon of the biceps brachii muscle to pass….

Where is the bicipital groove of humerus?
proximal humerus
The bicipital groove is located on the anterior surface of the proximal humerus with the following boundaries: superiorly: transverse humeral ligament. laterally: greater tuberosity of the humerus. medially: lesser tuberosity of the humerus.
What muscles attach to the bicipital groove of humerus?
The intertubercular sulcus, also known as the intertubercular groove, or bicipital groove, is a groove separating the greater and lesser tubercles of the humerus….The intertubercular sulcus is the site of three important muscle attachments:
- Pectoralis major.
- Latissmus dorsi.
- Teres major.
What is in the bicipital groove?
The bicipital groove is an indentation that lies along the anterior aspect of the proximal humerus and contains the tendon of the long head of the biceps brachii muscle (fig. 1 ).
What nerve runs in the bicipital groove?
The bicipital groove (intertubercular groove or sulcus) lies between the lateral edge of the lesser tuberosity medially and the greater tuberosity laterally. It is converted to a tunnel by the transverse humeral ligament, a thick band uniting the bony margins. . Musculocutaneous nerve (C5, 6 ).
What is located in the bicipital groove?
What tendon is in the bicipital groove?
long head of the biceps brachii muscle
Gross anatomy The bicipital groove is typically 4-6 mm deep 1. It contains the tendon of the long head of the biceps brachii muscle, which is ensheathed in a synovial reflection of the glenohumeral joint.
Where is the Bicipital tendon?
The long head biceps tendon lies in the bicipital groove of the humerus between the greater and lesser tuberosities and angles 90° inward at the upper end of the groove, crossing the humeral head to insert at the upper edge of the glenoid labrum and supraglenoid tubercle.
How do you put a bicep tendon back in groove?
Surgical Treatment If doctors suggest you a tenodesis surgery, they may perform an arthroscopy to remove a part of the long-head of the tendon (from the region of instability). Then they may directly reattach it through drill holes, seam anchors, or seam into the bone or soft tissue.
What is Bicipital tendon?
Bicipital tendinitis, or biceps tendinitis, is an inflammatory process of the long head of the biceps tendon and is a common cause of shoulder pain due to its position and function.
How do I know if my bicep tendon is out of groove?
Physical exam findings that may be suggestive of long head biceps tendon pathology (either subluxation or tendon tearing) include tenderness along the bicipital sheath, a positive “Speed’s Sign,” and pain with internal rotation.
Can a biceps tendon be repaired?
There are several procedures to accomplish reattachment of the distal biceps tendon to the forearm bone. Some techniques require two incisions while in others one incision may be sufficient. In some cases, the tendon is reattached using stitches passed through holes drilled in the bone.
