Table 1. Cranio-caudal Implant Overlap. Starting with full extension, the overlap of the implants in the sagittal plane began at 169.1° (SD: 3.5°) of elbow extension. Fifty percent of the UImpl were covered by HImpl at 153.8° (SD: 24.0°) of extension. Full coverage of the UImpl was present between 136.3° (SD: 22.6°) and 103.7° (SD: 20.4°). Implant overlap was reduced again to 50% at an extension angle of 88.9° (SD: 19.5°) and coverage was lost at an angle of 72.6° (SD: 20.3°).
