This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs.

OBJECTIVETo observe the anesthetic efficacy and safety of bilateral ultrasound-guided supraclavicular brachial plexus block in patients undergoing arthrolysis for shoulder periarthritis.
METHODSTwenty-seven patients (ASA class I-II) undergoing bilateral shoulder joint release surgery and 24 ml received bilateral ultrasound-guided supraclavicular brachial plexus block anesthesia with 0.4% ropivacaine and 0.8% lidocaine. The visual analogue scale (VAS) scores for shoulder joint pain were recorded before and after anesthesia. The efficacy of axillary nerve, dorsal scapular nerve and suprascapular nerve block was evaluated, and the anesthetic effect and complications was assessed during surgery. Before and after anesthesia, the range of left and right diaphragmatic muscle movement was measured when the patient took a quiet breath and a deep breath.
RESULTSThe patients showed no significant variations in MAP, HR, or SpO₂after anesthesia. The VAS scores of shoulder joint pain during anteflexion, abduction, posterior extension, rotation, posterior extension and medial rotation were significantly lowered after anesthesia (P<0.05), but the left and the right diaphragm movement range showed no significant difference between quiet breath and deep breath (P>0.05). The rates of complete block of the axillary nerve and dorsal scapular nerve was 100%, and that of suprascapular nerve was 92.6%. Partial phrenic nerve block occurred in 1 case with mild local anesthetic toxicity in another.
CONCLUSIONSBilateral ultrasound-guided supraclavicular brachial plexus block in patients has excellent analgesic effect in should joint release surgery with good safely.

A 59-year-old woman who had previously undergone an anatomic left total shoulder arthroplasty presented with increasing left shoulder pain and significant reduction in motion of the left shoulder joint. No evidence of prosthetic loosening or periprosthetic fracture was detected on the radiographs or fluoroscopic arthrogram images. Dual-energy computed tomography (DECT) images revealed evidence of loosening of the glenoid component and secondary rotator cuff failure. This case illustrates how a combination of detailed clinical history, careful physical examination and DECT arthrogram evaluation may be used to identify complications of an anatomic total shoulder arthroplasty.
