Conditions

Shoulder Impingement, Ultrasound Guided Injection

Brief summary

Shoulder pain, which is the third most common cause of musculoskeletal pain, has different etiologies. Muscle, bone structures and connective tissue pathologies can cause shoulder pain. Impingement syndrome (IS), which can cover many terms such as rotator cuff disorders, tendinitis and tears, is one of the most common pathologies of shoulder pain.

Detailed description

The hypothesis of this study was that injection types including ACJ would increase treatment efficacy.Therefore, this study investigated the six-month follow-up results of patients undergoing SA injection and SSNB and those receiving SA and ACJ injection.

Interventions

DRUGbupivacaine and methylprednisolone

5 mL of 0.25% bupivacaine containing 20 mg methylprednisolone was administered to the subacromial area

Inclusion criteria

* patients aged 18-65, * who were suffering from shoulder pain for more than three months and * who were diagnosed with IS. * All patients included in the study were diagnosed with IS using Shoulder Magnetic Resonance imaging.

Exclusion criteria

* the presence of cervical radiculopathy; * undergoing shoulder operation before; * the presence of central nervous system or * the presence of rheumatological disease, and polyneuropathy; * receiving physical therapy in the shoulder area with a diagnosis of IS within the last six months; and * receiving any injection therapy in the past.

Design outcomes

Primary

Measure	Time frame	Description
Visual Analogue Scale (VAS)	six month	for pain. 0: no pain at all, 10: worst pain imaginable

Secondary

Measure	Time frame	Description
Shoulder pain and disability index (SPADI)	six month	This scale was developed to measure pain and disability associated with shoulder pain. It consists of two parts evaluating pain and disability.
Short-Form 12 (SF-12)	six month	The SF-12 has a physical (SF12-PCS) and mental (SF12-MCS) state assessment scale
