54 patients were treated with hip/buttock pain requiring a diagnosis of gluteal tendinosis (a chronic tendon injury rather than an acute injury tendinitis). The study from the American Journal of Roentgenology demonstrated seventypercent of patients were satisfied with the results of the intervention which included a ultrasound guided cortisone injection. Typically these injections are done blind without image guidance. However the physician may miss the target site and may simply be injecting fatty tissue or the incorrect muscle or tendon causing further damage or discomfort by hitting painful structures like bone or nerve. If patients have great relief from this guided cortisone injection, the proper disgnosis is determined & the patient may be a candidate for other injectables which may be less damaging like PRP or Traumeel etc.
