Acromioclavicular Joint Pain: Prolotherapy, PRP and Stem Cells

The acromioclavicular  (AC) joint is a small joint on the top portion of the shoulder.   The joint created by the end of the clavicle (collar bone) and the winged protrusion of the shoulder blade (acromion).  The AC joint allows the ability to raise the arm above the head.

The joint is stabilized by three ligaments:  acromioclavicular ligament, coracoacrominal ligament and coracoclavicular ligament

At the Centeno-Schultz Clinic AC joint injuries are graded  using the Rockwood scale.
Type I:
– sprain of joint with out a complete tear of either ligament.  The ligament is intact but stretched.
Type II:
– tear of AC ligaments w/ coracoclavicular ligaments intact;
– will not show marked elevation of lateral end of clavicle;
Type III:
– in this injury both AC & CC ligaments are torn;
> 5 mm elevation of AC joint w/o weights is consistent w/ severe type II or a type III injury.

MSK ultrasound is utilized in the treatment of AC joint injuries given that both the joint and the supporting ligaments require treatment.  The perils of blind injections have been discussed previously.  Prolotherapy, Regenexx SCP and  Regenexx SD has been successful in the treatment of AC joint injuries at the Centeno-Schultz Clinic.
