The treatments for subdeltoid bursitis include physical therapy, medication and surgery. 1. Physiotherapy: It is mainly to relieve pain, prevent adhesion of the bursa and restore the normal function of the shoulder joint. In the acute stage of subdeltoid bursitis, the forearm can be suspended and braked, or the shoulder joint can be braked with a brace in the position of 90° abduction. Localized hot compresses, acupuncture, massage, etc. can be used to loosen the bursa and loosen the adhesion. 2. Drug treatment: hydrocortisone acetate and procaine can be injected into the bursa. In addition to physical therapy and medication, the range of motion should be gradually expanded to restore joint function. 3. Surgical treatment: For intractable painful subdeltoid bursitis, surgical resection of the bursa may be considered if non-surgical treatment is ineffective. For patients whose bursa thickening seriously affects shoulder abduction, the acromion can be removed. If the diagnosis of subdeltoid bursitis is confirmed, early and standardized treatment is recommended to reduce the adverse effects of the disease. All the above medications should be used under the guidance of a doctor or pharmacist, avoid self-medication.
