Hip Pain in the Young
Peter Asnis, MD
Orthopaedic Sports Medicine
Massachusetts General Hospital, Harvard Medical School,
Boston, MA
Grand Rounds presented on November 26th 2008 at the O’Keefe Auditorium, Massachusetts General Hospital, Boston, MA
Dr Asnis reviews the diagnosis and treatment of hip pain in young patients. He goes over the physical exam and an appropriate radiographic work-up. The differential diagnosis for hip pain in the young is discussed. The treatment algorithm for several common problems is outlined. Special attention is paid to the treatment of labral tears and femoroacetabular impingement.

Exercises for Strong and Healthy Shoulders
Shoulders permit our arms to move in a wide arc and perform elaborate activities. This mobility is due to superb coordination of muscles and soft tissues around the shoulder and shoulder blades (scapula, SKA-pew-la), and is essential for performing activities in a pain- and injury-free manner. See related article on Rotator Cuff complications impairing shoulder movement.
Conventional shoulder exercises strengthen the larger muscles but tend to overlook the mid-back muscles that stabilize the scapulas. This can often result in muscle imbalance and consequently, bad posture. Even non-shoulder exercises like running on a treadmill with shoulders slouched can lead to stiffness and pain. These conditions increase injury potential and thus the need for corrective exercises.
Michael Bento, personal trainer at the Clubs at Charles River Park, Boston, demonstrates simple exercises you can do at home to develop shoulder strength and protect them from injury. As a bonus, these exercises also help tone the all important core muscles.
These exercises can be performed on a stability ball as shown, or on a work bench. Dumbbells or additional weights are not required. And as I surprisingly found out last week, you can do these scapular exercises while standing and starting with the arms in front! Yaay!

There are several causes of shoulder pain. In the elderly, shoulder pain is commonly associated with aging and can be traced to rotator cuff disease. In younger people, it is associated with throwing or overhead sporting activities that result in injury to the rotator cuff.
The rotator cuff is a band of four muscles and tendons at the shoulder joint, which grasp the end of the upper arm or humerus (HYU-mer-us, see figure), much like four fingers holding a baseball. The rotator cuff thus stabilizes the shoulder joint and provides exceptional mobility to the arm. Pinching, irritation, or tears of the rotator cuff are common causes of shoulder pain.
Impingement
Rotator cuff tendons are separated from overlying bones by a soft tissue sac or bursa, allowing them to glide easily. According to one theory, repetitive motion of the arm causes pinching of this sac in the tight space between the acromion (a-KRO-me-un) and humerus (see figure), resulting in irritation, swelling and pain. This inflammation of the bursa and tendons is called impingement. The pain is characteristically worse when the arm is lifted and common at night.
