* Values are expressed as mean, with SD in parentheses; †collapse with prominent hardware, disabling elbow stiffness (concomitant complex regional pain syndrome [n = 1; simple group], ulnar neuritis [n = 1; complex group]), or posterolateral joint subluxation requiring external fixation revision (n = 1; complex group); ‡one patient underwent concomitant ulnar nerve transposition; §at least mild joint space narrowing and mild osteophyte formation (Broberg-Morrey Grade 1 posttraumatic arthritis of the elbow) compared to radiographs of the contralateral elbow; ∥including subtle irregularity of the subchondral bone, osteopenia, or cysts not sufficient to warrant the diagnosis of mild radiographic arthritis (any joint space narrowing, osteophyte formation compared bilaterally); ¶crepitus noted in the radiocapitellar joint and/or the ulnohumeral joint; #unpaired t-test; **Fisher’s exact test; PREE = Patient-rated Elbow Evaluation.
