Ac Joint Nerve Block

Preemptive nerve blocks are meant to prevent subsequent pain from a procedure that can cause problems including phantom limb pain.

Ac joint nerve block. This dual innervation was from the articular branches of the suprascapular nerve and of the lateral pectoral nerve. To optimize the effectiveness of shoulder denervation it requires a detailed understanding of the nerve supply to the glenohumeral and acromioclavicular joints relative to. Recognizing that the axillary nerve was most likely affected by the acromioclavicular dislocation and was therefore responsible for symptoms the authors anticipated that targeting the c5 c6 origin by interscalene block with a peripheral nerve stimulator could provide sustained post operative analgesia for the patient. However because of the reported side effects of isb the use of a suprascapular nerve block ssnb has been described as an alternative strategy with fewer reported side effects.

Just as surgical technique relies on surgical anatomy or pathology leans on pathologic anatomy the anatomic information necessary for the practice of regional anesthesia must be specific to this application. Nerve blocks can be used in some cases to avoid surgery. Ultrasound guided nerve blocks of upper extremity in the 21st century new techniques and management duration. Background and objectives in 2011 chronic shoulder joint pain was reported by 18 7 million americans.

The acromioclavicular joint is a synovial joint with the articular surfaces separated by a wedge shaped fibrocartilaginous disc asterisk the inferior surface of the joint is in direct contact with the subacromial bursa and supraspinatus muscle and may play a role in the development of the impingement syndrome reproduced with permission from philip peng educational series. Documenting the detailed anatomy of this innervation in the ac joint including the pertinent surgical and anatomic relationships of the suprascapular nerve and its branches to the ac joint will aid in the prevention of injury and the reduction of risk of denervation during shoulder surgery. A consistent pattern of innervation of the posterior and inferior shoulder joints also is described. The practice of regional anesthesia is inconceivable without sound knowledge of the functional regional anesthesia anatomy.

Constant relationship of these 2 nerves to bony landmarks will permit anesthetic blocks for diagnosis and possible therapeutic intervention. Image guided radiofrequency ablation has emerged as an alternative intervention to manage chronic shoulder joint pain. This is not an invasive technique but one where local anaesthetic and cortisone a steroid is injected into the muscle in the region. The interscalene brachial plexus block isb is commonly used.

The injection of this nerve numbing substance is called a nerve block. If the nerve pain is not responding to conservative treatment such as anti neuropathic medication a nerve block is worth considering.
