A 69-year-old woman was admitted to the emergency department after an accidental fall. She presented with left shoulder pain and functional impairment. Clinical history included essential hypertension and obesity. Traditional X-ray series and computed tomography (CT) scan with three-dimensional reconstruction were performed. Examinations showed a 3-part fracture of the proximal left humerus, accounting to the Neer's classification (AO/ASIF: 11-B2) [Figure and ]. Two days after patient acceptance to our department, fracture was treated by closed reduction and fixation with two retrograde K-wires and one threaded wire, by mean of a modified “en palmière” technique: The first two wires were retrograde nonthreaded bent wires inserted at the deltoid “V” level, while the latter was an anterograde threaded wire percutaneously introduced to fix the great tuberosity [Figure and ]. Two days after surgery, the patient was discharged from the hospital. One month after surgery, the patient came back for routine clinical and radiographic control, to evaluate the fracture healing and eventually plan the wires removal. In that setting, she referred about global well-being and no pain at the shoulder. X-rays demonstrated the intrathoracic migration of the threaded wire used for tuberosity fixation [Figure and ]. A complementary CT scan was immediately performed to better show the spatial relationship between the wire and intrathoracic vital organs. It revealed the device was migrated through the fifth intercostal space to the left lung parenchyma, without the signs of pneumothorax, nor bleeding [Figure and ]. She was extensively interviewed and investigated for any symptom or sign. She only referred about episodic intercostal mild pain that onset 1 week after surgery and was elicited by a cough. Due to low severity of the symptom, it was completely underestimated by the patient. Physical examination, vital parameters, and blood examination resulted normal. The patient was immediately managed by mean of video-assisted thoracoscopic approach to remove the migrated wire from the lung parenchyma. Intraoperatively, a fibrin-coated spot was identified on the lung surface and excised. This allowed the foreign body to be visualized and easily removed []. Neither parenchymal bleeding nor pneumothorax was observed. A chest drain tube was inserted, and antibiotic prophylaxis was administered. The postoperative outcome was free of complications, and the patient was discharged 3 days after surgery with a normal chest radiogram. One month after surgery, the patient underwent new thoracic and left shoulder X-rays, confirming the healing of the shoulder fracture and the absence of radiographically evident sequelae about the lung. A specialist consultation by thoracic surgeons was performed, assessing the complete recovery of lung function without complications or negative outcomes.
A 52-year-old man underwent surgery for an AC joint dislocation 5 years ago. The dislocation was fixed using a K-wire. The patient did not require a follow-up appointment as he had no complaints. The patient's dominant extremity was right-sided and he was a retired construction worker. The patient presented to our outpatient clinic with swelling at the back of the neck. Radiological evaluation revealed that a broken tip of the K-wire used in the fixation of the AC joint dislocation had migrated to the back of the neck (). The broken K-wire was removed under local anaesthesia via mini-incision (). No intervention was performed for the AC joint. The remaining broken pin was not removed from the shoulder.
