CASE A 71-year-old man with a proximal humerus fracture nonunion underwent surgery augmented by a fibular cortical strut allograft. On placing the allograft within the proximal humerus, fluoroscopic images showed 2 foreign bodies found to be broken drill bits located within the allograft. The drill bits were extracted, and the allograft was reprepared for use. CONCLUSION After 2 years of follow-up, no significant sequela related to the foreign bodies was noted. To the best of our knowledge, this case report represents the first-of-its-kind occurrence of broken drill bits found within bone allograft.

Case Avascular necrosis (AVN) and nonunion are common complications encountered with scaphoid waist fractures. We present a case of a 23-year-old man presenting with a right scaphoid fracture nonunion associated with AVN of the proximal pole. He was treated with a 1,2 intercompartmental supraretinacular arterial bone graft (Zaidemberg technique) in combination with a dorsal plate yielding excellent functional and radiographic results. Conclusion Scaphoid waist fracture nonunion with AVN of the proximal pole is challenging to treat and combining the Zaidemberg technique along with dorsal plating allows for easy access and excellent healing.

Case Although congenital nonunion of the clavicle is a well-known pathology in children, posttraumatic nonunion is a rare entity. Nonunion after open reduction and internal fixation of a clavicle fracture is exceptional in the pediatric population. We report on a patient presenting posttraumatic pseudarthrosis of the clavicle after surgical treatment. Pseudarthrosis was resected, and the defect was bridged with an iliac crest autograft, supplemented with bone morphogenetic protein, and fixed with an elastic stable intramedullary nail. Conclusion This procedure offered enough stability for achieving fracture consolidation and is a safe alternative to plating in clavicle nonunion.

CASE A 54-year-old man presented with a comminuted left midclavicle fracture that progressed to a symptomatic nonunion after nonsurgical management. Nonunion open reduction and internal fixation (ORIF) was performed, but a left brachial plexopathy developed 48 hours postoperatively. Imaging failed to demonstrate an emergent cause. The patient was monitored and completely recovered, with occasional neuralgia and mildly limited forward elevation of the shoulder. CONCLUSION Development of a brachial plexopathy 48 hours after routine clavicle nonunion ORIF using plate fixation is an unusual complication. Future studies are needed to determine if this "wait-and-see" approach can be generalized to similar cases.

CASE We describe 2 patients with nonunion of the clavicle and dynamic compression of the subclavian artery. In both patients, no structural abnormality of the subclavian vessels was evident at rest; however, with the arm in hyperabduction, arterial occlusion occurred because of the mobility of the fracture and a prominent callus. CONCLUSION This small case series demonstrates an important and, to our knowledge, unreported clinical complication of clavicle fracture nonunion. We believe that this complication is worth considering as a rare but important cause of pain in patients with delayed union or nonunion of the clavicle.

Case: Two cases of symptomatic distal phalangeal fracture nonunion that were treated with a course of digital splinting and daily external low-intensity pulsed ultrasound (LIPUS) treatment are presented. Osseous union, symptom resolution, and full range of motion were successfully achieved in both cases without surgery. Conclusion: Digital splinting and daily LIPUS should be considered as a treatment option for symptomatic nonunion of the distal phalanx in cases that do not require correction of bone deformity.

Case: A fifty-one-year-old female runner developed a stress fracture of the inferior pubic ramus. Nonoperative treatment was initiated, but the symptoms persisted and she was diagnosed with a nonunion. After eleven months of symptoms and ten months of nonoperative treatment, including four months of complete avoidance of running, percutaneous screw fixation was performed, with radiographic and clinical healing of the fracture. Conclusion: While inferior pubic ramus stress fractures are usually successfully treated nonoperatively, instances of nonunion and delayed union have been described. In the present report, we describe the case of a patient in whom an inferior pubic ramus stress fracture nonunion was successfully treated with minimally invasive screw fixation.
