Newcastle approach to the elbow, a cadaveric study

The aim of the current study was to assess the amount of the distal humerus articular surface exposed through the Newcastle approach, a posterior triceps preserving exposure of the elbow joint.
Twenty-four cadaveric elbows (12 pairs) were randomized to receive one of the four posterior surgical approaches: triceps reflecting, triceps splitting, olecranon osteotomy and Newcastle approach. The ratio of the articular surface exposed for each elbow was calculated and compared.
The highest ratio observed was for Newcastle approach (0.75 ± 0.12) followed by olecranon osteotomy (0.51 ± 0.1), triceps reflecting (0.37 ± 0.08) and triceps splitting (0.35 ± 0.07). The differences between Newcastle approach and other approaches were statistically significant (p = 0.003 vs. osteotomy and <0.0001 vs. triceps reflecting and splitting).
The Newcastle approach sufficiently exposes the distal humerus for arthroplasty or fracture fixation purposes. Its use is supported by the current study.
