INDICATIONS 1.Osteoarthritis 2.Adhesive Capsulitis (frozen shoulder) typically occurs after prolonged immobility of the arm. It can be associated with diabetes and thyroid disorders. Remarkably, findings on radiography will often be normal 3.Rheumatoid arthritis SHOULDER JOINT

TECHNIQUE Blind: 30% Both ultrasound guidance (USG) and fluoroscopy: 65% to 90% Anterior or Posterior approach

Blind Anterior Approach:

INDICATIONS 1.Osteolysis of the distal clavicle a degenerative process that results in chronic pain, particularly with adduction movements of the shoulder and is typically seen secondary to traumatic injury or in persons who perform repetitive weight training involving the shoulder. 2.Osteoarthritis ACROMIO-CLAVICULAR JOINT INJECTION

TECHNIQUE 1.Blind : 40% 2.Fluoroscopic: 100% ACROMIO-CLAVICULAR JOINT INJECTION

HIP JOINT Knee pain was reported by 18% Hip pain by 7% The most common: osteoarthritis inflammatory arthritides: 1.Rheumatoid arthritis 2.Psoriatic arthritis 3.Trauma infection 4.Avascular necrosis

TECHNIQUE The anterior and lateral approaches are the most commonly used techniques However, neither technique can be reliably used without radiologic guidance although the lateral approach is thought to be safer than the anterior approach. 60% success rate with the anterior approach 80% success with the lateral technique

KNEE JOINT Osteoarthritis of the knee is the most common form of arthritis and the major cause of disability and reduced activity in people older than 50 years. Thirty percent of people older than 50 years have radiographic evidence of osteoarthritis of the knee, which increases up to 80% after age 65.
