During subperiosteal elevation, the ulnar nerve was identified and raised off the ulna subperiosteally and mobilized submuscularly anterior to the medial epicondyle to protect the nerve. The nerve was released only laterally off the triceps, and the medial soft tissue attachment is maintained. The main outcome measurements was rate of neuritis documented within physical examination.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>Within the 125 patients, 35 underwent subperiosteal elevation (mean age of 56 \u00b1 21 years, 57% female), 63 in situ decompression (mean age of 60 \u00b1 18 years, 46% female), and 27 anterior transposition (mean age of 55 \u00b1 20 years, 59% female). Preoperative ulnar neuritis was present in 34%, 21%, and 33% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.26). At postoperative evaluation, symptom resolution occurred in 100%, 69%, and 33% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.003). New cases of postoperative ulnar neuritis occurred in 6%, 8%, and 26% of patients treated with subperiosteal elevation, in situ decompression, and anterior transposition, respectively (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.054). Subperiosteal elevation outperformed anterior transposition regarding postoperative ulnar neuritis (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.019) and symptom resolution (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.002) and performed similarly to in situ decompression (<jats:italic toggle=\"yes\">P<\/jats:italic> &gt; 0.05). On multiple regression analysis, anterior transposition was an independent risk factor for postoperative neuritis (OR = 5.2, <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.023).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Subperiosteal elevation is an effective way to minimize postoperative neuritis and similar to an in situ decompression during distal humerus fracture fixation. Based on the results of this cohort, authors recommended that anterior transposition of the ulnar nerve be used with caution due to its association with postoperative ulnar neuritis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n            <jats:p>Therapeutic, Level III.
