Hip labral (labrum) tears
Most labral tears are not associated with a traumatic onset. Running, sprinting, and frequent rotation of the hip while playing sports is thought to result in tears of the labrum. Bony structural risk factors include hip dysplasia and femoroacetabular impingement (FAI). Clinical assessment including history, physical, and radiographic analysis is 98% accurate in determining the presence of an abnormality within the hip joint. MRI with contrast injected into the hip joint(arthrography) is 65-90% sensitive for detecting labral tears. Relief of pain (lidocaine pain test) from an intraarticular anesthetic injection at the time of arthrography is very suggestive of intraarticular abnormalities and is useful in predicting improvement with arthroscopic intervention, particularly in patients with normal imaging exams.
Signs and Symptoms
In greater than 90% of patients with labral tears, pain is reported in the anterior hip or groin region. Less often pain occurs in the lateral or posterior hip region. Patients may also report clicking, catching, locking, or giving away. Range of motion restrictions in flexion, internal rotation, and/or figure four position may be noted. Provocative tests include the anterior impingement test of flexion, internal rotation, and adduction. A positive test causes pain in the groin and restricted motion. Pain in the joint with a resisted straight leg raise may be indicative of a labral tear.
Treatment
Unfortunately the labrum does not heal on its own if it is torn. The goak of non-operative treatment is to reduce the symptoms. If non-operative methods fail, surgical intervention of labral tears may be performed open or arthroscopically. The labrum can be debrided (cleaned-up) and/or repaired with suture anchors. Histologic studies have shown potential for labral healing. Conservative treatment may include limited weight bearing, NSAIDS, and avoidance of pivoting motions on the hip. Physical therapy can improve muscle recruitment to control hip motion.

Why the hype about minimally invasive surgery?
I commonly have been asked by family members and friends about minimally invasive techniques, as they are increasing advertised for a variety of different surgical procedures. The questions can best be summarized by “should I have my surgery done that way?”
The goals of minimally invasive surgery are much the same as for the traditional “open” surgeries of the past. The difference is that the incisions are smaller, and in general, there is less dissection, less bleeding, and less pain, and thereby quicker rehabilitation. But these less invasive procedures must be considered with caution, as the visualization during surgery is oftentimes decreased. Less invasive does not necessarily result in better outcomes, particularly when considered in the long term. And certain procedures, such as bunion surgery, have been shown to have worse results when performed in a less invasive manner.
One such type of minimally invasive surgery is arthroscopic surgery. Arthroscopy utilizes small portals (1 to 2 cm incisions) to pass cameras and instruments to perform the surgery. Saline water is used to fill the joint and to view the procedure. This type of surgery has become a standard of care for certain injuries such as anterior cruciate ligament (
