Frozen shoulder is a syndrome caused by chronic inflammation and adhesions in the muscles, tendons, bursa and joint capsule around the shoulder joint, resulting in pain and impaired movement around the shoulder joint. For the treatment of frozen shoulder, the pain clinic has a unique approach, and the general treatment principles are as follows. 1.General treatment Oral anti-inflammatory and analgesic drugs and herbs for blood circulation, external application of rubs and patches, physiotherapy and massage, etc. It is suitable for light and early cases, or as an adjunct to other treatments. 2.Nerve block therapy: suprascapular nerve block, axillary nerve block, pressure point block around shoulder joint, stellate ganglion block. 3.Small needle knife therapy Apply small needle knife treatment to the bursa, tendon sheath, muscle tension and myofascial adhesions, etc., which are obvious in pressure pain, after blocking the painful point, and when withdrawing the needle, form a skin mound inside the blocked skin, pierce the needle knife through the skin mound, reach the lesion tissue, peel off and release the adhesions, cut the scar and shred the calcified block, etc., which can receive immediate effect, but only limited to the lesion. 4.Manipulative release under anesthesia For those who have developed frozen shoulder and have significantly limited function, intravenous general anesthesia or interosseous plexus or suprascapular nerve block can be used, and after the block is perfected, soft tissue adhesions around the shoulder joint can be released by manipulation.
