The 'upper deck' view is an arthroscopic perspective which visualizes the labral-osseous junction without detachment of the chondro-labral junction. The aim of this study was to evaluate the utility of the 'upper deck' view in preventing incomplete acetabuloplasty. Data were prospectively collected from September 2016 to November 2016 for all hip arthroscopies. We recorded the amount and clock-face of residual pincer-lesion acetabular bone resected using the 'upper deck' view. We noted whether this residual pincer-lesion acetabular bone was visible fluoroscopically, as well as the amount and clock-face of the overall acetabuloplasty. During the study period, 87 hip arthroscopies were performed; 50 met the inclusion criteria. Forty-six (92%) patients had residual pincer-lesion acetabular bone after completion of the acetabuloplasty resected from the bird's eye view. In all such cases the residual pincer-lesion acetabular bone was not visible under fluoroscopy and could only be detected using this specific view. The average maximum resection for the acetabuloplasty was 2.1 ± 0.9 and 1.4 ± 0.5 mm (P = 0.16) for resection of residual pincer-lesion acetabular bone. The 'upper deck' view provides the ability to decrease the risk of incomplete acetabuloplasty, due to the high likelihood (92%) of a residual beak of pincer-lesion acetabular bone when this view is not used during rim trimming.
“上甲板”视图是一种关节镜视角，可在不分离软骨盂唇交界的情况下观察盂唇骨交界。本研究的目的是评估“上甲板”视图在预防髋臼成形术不完整方面的效用。前瞻性收集了2016年9月至2016年11月期间所有髋关节镜检查的数据。我们记录了使用“上甲板”视图切除的残余钳夹性病变髋臼骨的量和钟面位置。我们记录了这种残余钳夹性病变髋臼骨在荧光透视下是否可见，以及整个髋臼成形术的量和钟面位置。在研究期间，共进行了87例髋关节镜检查；50例符合纳入标准。46例（92%）患者在从鸟瞰视图完成髋臼成形术后有残余钳夹性病变髋臼骨。在所有这些病例中，残余钳夹性病变髋臼骨在荧光透视下不可见，只能通过这种特定视图检测到。髋臼成形术的平均最大切除量为2.1±0.9mm，残余钳夹性病变髋臼骨切除量为1.4±0.5mm（P = 0.16）。“上甲板”视图能够降低髋臼成形术不完整的风险，因为在髋臼缘修整过程中不使用此视图时，残余钳夹性病变髋臼骨喙的可能性很高（92%）。
