ReviewAssessment and differential diagnosis of the painful hip.
Hip pain is a common problem seen by orthopaedic surgeons. The current authors provide an approach to the patient with hip pain, including important information to be gained from the history and physical examination and relevant radiographic studies and laboratory tests. A differential diagnosis for patients presenting with the complaint of hip pain and indications for hip arthroscopy are provided.

Effect of arthroscopic procedures on the acromioclavicular joint.
The objective of the current study was to determine the effect of arthroscopic acromioplasty, and combined acromioplasty and distal clavicle resection on joint kinematics and in situ forces in response to an anterior, posterior, and superior load of 70 N. The loading conditions were applied to 10 fresh-frozen cadaveric shoulders using a robotic and universal force and moment sensor testing system. Translations in response to a posterior load increased by approximately 30% after combined acromioplasty and distal clavicle resection when compared with the intact and acromioplasty conditions. ⋯ The results suggest that an arthroscopic acromioplasty alone does not significantly affect the mechanics of the acromioclavicular joint with these loading conditions. However, an acromioplasty combined with a distal clavicular resection does result in significant increases in joint motion and ligament forces. In some circumstances, such as after a previous joint separation, the increased forces in the coracoclavicular ligaments could result in additional damage to weak ligaments.
