The Ulnar Nerve in Elbow Trauma

Predictors of Diagnosis of Ulnar Neuropathy After Surgically Treated Distal Humerus Fractures

“…In addition, most studies do not distinguish among pre-existing nerve dysfunction due to cubital tunnel syndrome, injuryrelated ulnar nerve palsy, iatrogenic ulnar nerve palsy, and delayed-onset ulnar nerve palsy. 3 Potential contributions to iatrogenic ulnar neuropathy include the proximity of the nerve to the injury zone and handling of the nerve (stretch, compression, devas-…”

“…On the other hand, transposition requires further dissection of the nerve with potential for additional stretch, pressure, and devascularization. 10,11 Most authors support routine anterior transposition of the nerve, 3,8,[12][13][14] but some authors advocate placing the nerve back into its epicondylar groove after internal fixation is completed. 15,16 Others transpose the nerve only when it is contused or if it lies directly on the medial plate.…”

“…The odds of ulnar neuropathy were substantially greater for columnar fractures than for capitellar/ trochlea fractures (odds ratio 8.14; 95% confidence interval, 1.03-64. 3), but the model explained only 11% of the variance in risk for ulnar neuropathy after distal humerus fracture.…”

Medial mini-open versus percutaneous pin fixation for type 3 supracondylar fractures in children

“…Alterations in sensory conduction are more sensitive indicators of nerve injury and found to correlate more directly with physical examination findings. [22] In the present patients, monofilament test was conducted at 1 postoperative week. Group A had 3 poor and 1 fair results, while Group B had 2 poor and 1 fair results.…”

Arthroplasty in Elbow Fracture Treatment

“…The reported postoperative incidence of ulnar nerve affection varies widely between 0 and 51% (Holdsworth and Mossad 1990, Sodergard et al 1992, Wang et al 1994, Kundel et al 1996, Gupta and Khanchandani 2002, Soon et al 2004, Shin and Ring 2007, Wiggers et al 2012). Svernlov et al found that 27% of patients had ulnar nerve affection after 48 months, but interestingly this was regardless of whether the medial column was involved in the fracture and secured with a plate and screws or not (Svernlov et al 2017).…”
