Biceps-Labrum Complex Disorders

Controversy exists among shoulder surgeons over the role of the labrum and biceps as pain generators in the shoulder, and there seems to be increasingly polarizing points of view. Some argue that the labrum is a common pain generator, especially in young athletes, while others contend that the labrum is not a common pain generator and is over diagnosed as such. Similarly, as some shoulder surgeons argue that the long bead of the biceps tendon is a common pain generator, others assert that it is, as well, over diagnosed, and over treated. The work Dr. O’Brien has been doing in this area over the last ten years has led him to the conclusion that there should be a paradigm shift in the way we think about this issue. He believes that the anatomy and clinical functionality of the biceps and labrum work as ONE structure, the Biceps-Labrum Complex, instead of two separate entities. Dr. O’Brien has developed a clinical testing system, called the “3-Pack” along with an arthroscopic exam which guides him in the diagnosis of a patient’s pain. He is currently validating this clinical examination testing system with arthroscopic correlations noted during surgery.

An important outcome of Dr. O’Brien’s testing has been the development of a new surgical procedure called the Biceps Transfer. Dr. O’Brien created this procedure in 2002, and has since performed over 600 biceps transfers. The procedure, designed to fill a void in orthopaedic surgery on treatment options for the long head of the biceps tendon, has been extremely successful in Dr. O’Brien’s hands.
In order to continue to better understand the idea of the biceps-labrum complex, Dr. O’Brien and his research team are actively involved in different research studies for patients who are treated for shoulder pathology under his care. Each research project aims to address a different stage of the diagnosis and treatment processes. Below is a list of projects that are currently underway:

  • Biceps Tenodesis: A Comparison of Tendon-to-bone And Tendon-to-tendon Healing In A Rat Model
    The purpose of this study has been to determine the impact of tenodesis location on tissue healing and inflammation based upon histologic and immunohistochemical analysis in a rat model.
  • The “3-Pack” Examination: Validated Objective Criteria to Clinically Identify Bicipital Etiology of Shoulder Pain, #10116
    Documents initial exams and questionnaires performed by Dr. O’Brien and research team, results of arthroscopic examination performed during biceps transfer surgery, and results short term follow up exams (from 6 weeks to 1 year post op)
  • Medium term results of transfer of the long head of the biceps tendon: 2-5 year follow up, #10127
    Documents medium term follow up exams and questionnaires performed by Dr. O’Brien and research team, evaluates econometrics of transfer surgery compared with other treatments, as well as patient satisfaction with outcomes

Knees

Another focus of Dr. O’Brien’s research is the Anterior Cruciate Ligament, or ACL. Dr. O’Brien performs roughly 100 ACL reconstruction surgeries a year.
