A fracture of the distal radius with an associated injury to the ulnar nerve is rare. The management of the ulnar nerve lesion is unclear. We present a patient with a closed distal radius fracture related to an injury to the ulnar nerve associated with diminished sensation and a claw deformity. This was assessed by ultrasonography (US) that showed the nerve to be in continuity without any evidence of compression. The nerve was deviated towards the volar side at the distal end of the ulna and was enlarged at the same point. Open reduction and internal fixation was performed for the fracture. Emergent nerve exploration was not performed. The function of the ulnar nerve was completely restored at 16 weeks after injury. In cases presenting with ulnar nerve injury, we recommend US to evaluate the condition of the ulnar nerve. Nerve exploration should be performed when neurological deficits were found on US or symptoms did not recover over 4 months observation. Level of Evidence: Level V (Therapeutic) [ABSTRACT FROM AUTHOR]

Case: We encountered a case of entrapment of the ulnar nerve and artery associated with displaced distal radius and ulna fracture. After the closed reduction, a patient noted a severe sensory deficit and had claw hand. Intraoperatively, the proximal edge of the fractured radius was positioned in the space between the ulnar artery and the nerve, and the nerve was entrapped. The entrapment was released surgically with a good 1-year outcome. Conclusion: In cases of distal radius fracture, there is a possibility of entrapment of the ulnar nerve. When neurological symptoms worsen after the reduction maneuver, early nerve exploration is needed. [ABSTRACT FROM AUTHOR]

Case: A 19-year-old college baseball outfielder presented with a 3-month history of right shoulder pain. Radiographs, computed tomography, and magnetic resonance imaging showed a large osteochondral defect at the posterosuperior aspect of the glenoid. Arthroscopic evaluation identified an unstable fragment that was partially attached. Fixation of the osteochondral fragment was achieved with autogenous osteochondral plugs through a posterior arthrotomy. At 8 months after surgery, the patient was able to return to his former competitive level of performance. Conclusion: Osteochondritis dissecans (OCD) rarely affects the glenoid. Fixation of a large glenoid OCD lesion with autogenous osteochondral plugs was a successful treatment in this patient. [ABSTRACT FROM AUTHOR]
