Abstrakt: Background: O'Driscoll popularized the principle of linked column fixation for distal humerus fractures. Despite the linked column concept being widely accepted, there are few reported techniques to accomplish this goal. A novel device was designed based on the principles of linked columns. An interlocking beam is used to connect the medial and lateral plates, creating a unified fixed angle construct. Our primary objective was to report clinical outcomes across multiple institutions for a linking beam used in distal humerus fracture fixation.
Methods: A retrospective series was collected from 5 institutions for the TiBeam (Skeletal Dynamics) with a minimum follow-up of 6 months. Acute and chronic treatment of distal humerus fracture patterns and all plate configurations were included for analysis.
Results: A total of 36 cases were collected at a mean age of 52 years and a mean follow-up of 19.3 months. AO C-type fractures were 56% of the series. The median Mayo Elbow Performance Score was 85 (interquartile range [IQR] 76.3-90), the median DASH was 21.4 (IQR 15.9-30), and the median score on the visual analog scale for pain during activities of daily living was 3.5 (IQR 2-5). An olecranon osteotomy was used in 86% of cases, and an anatomic plate was used for fixation of the osteotomy in 94% of those cases. There were 3 cases of olecranon plate removal for a rate across the series of 13.7%.
Discussion: Our short-term results demonstrate satisfactory clinical outcomes with low rates of revision for distal humerus fracture fixed with a linking beam. Further, the rate of removal for the olecranon osteotomy plate was lower than historical reports for aggregate methods of osteotomy fixation.
