    Abstract Background: Distal humerus fractures are common and can be difficult to treat. No one approach to the distal humerus has been shown to be superior to another; however, the olecranon osteotomy remains the gold standard for complex, intra-articular fractures. Understanding the percent of articular exposure with approaches to the distal humerus is important for success. The goal of this study is to show the percent of articular exposure of the triceps fascial tongue approach as compared with the olecranon osteotomy.
    Methods: Twelve fresh frozen cadavers were separated randomly into 2 groups of 6 each. The first group of 6 specimens was allocated to the triceps fascial tongue approaches with the collaterals maintained and with the collaterals released off the ulna and elbow dislocated. The second group of 6 was allocated to the triceps fascial tongue approach while maintaining the collaterals followed by an olecranon osteotomy. The articular exposure was marked after performing each approach, and the percent of articular exposure was quantified by using 3D scanning. Standard deviations were calculated for each.
    Results: The average percent visualization of the distal humerus articular surface in the fascial tongue approach while maintaining the collaterals was 36% in the first cohort and 37% in the second cohort with a standard deviation of 5% in both cohorts. The average percent of the distal humerus articular surface exposed in the fascial tongue approach with the collaterals released off the ulna and elbow dislocated was 85.09% with a standard deviation of 4%. The average percent of the distal humerus articular surface exposed in the olecranon osteotomy group was 57.9% with a standard deviation of 5%.
    Conclusion: The triceps fascial tongue approach allows for visualization of about one-third of the joint, which may be adequate for many intra-articular distal humerus fractures. For added exposure of the articular surface, the collaterals may be elevated from the ulna and the elbow dislocated allowing for a substantial increase in percent of articular exposure compared with the collateral retaining fascial tongue approach and the olecranon osteotomy.

    Abstract Background: There is no consensus in the foot and ankle literature regarding how to measure pronation of the first metatarsal in patients with hallux valgus. The primary purpose of this study was to compare 2 previously published methods for measuring pronation of the first metatarsal and a novel 3-dimensional measurement of pronation to determine if different measurements of pronation are associated with each other.
    Methods: Thirty patients who underwent a modified Lapidus procedure for their hallux valgus deformity were included in this study. Pronation of the first metatarsal was measured on weightbearing computed tomography (WBCT) scans using the α angle with reference to the floor, a 3-dimensional computer-aided design (3D CAD) calculation with reference to the second metatarsal, and a novel method, called the triplanar angle of pronation (TAP), that included references to both the floor (floor TAP) and base of the second metatarsal (second TAP). Pearson's correlation coefficients were used to determine if the 3 calculated angles of pronation correlated to each other.
    Results: Preoperative and postoperative α angle and 3D CAD had no correlation with each other (
    Conclusion: The calculation of first metatarsal pronation is affected by the reference and technique used, and further work is needed to establish a consistent measurement for the foot and ankle community.
    Level of evidence: Level III, retrospective cohort study.
