Abstract：
UNASSIGNED: The purpose of this study was to quantify the articular surfaces of the naviculocuneiform (NC) joint to help clinicians better understand common pathologies observed such as navicular stress fractures and arthrodesis nonunions.
UNASSIGNED: Twenty cadaver NC joints were dissected and the articular cartilage of the navicular, medial, middle, and lateral cuneiforms were quantified by calibrated digital imaging software. Statistical analysis included calculating the mean cartilage surface area dimensions of the distal navicular and proximal cuneiform bones. Length measurements on the navicular were obtained to estimate the geographic location of the interfacet ridges. Lastly, all facets of the articular surfaces were described in regard to the shape and location of cartilaginous or fibrous components. Results were compared using Student t tests.
UNASSIGNED: Navicular cartilage was present over 75.4% of the surface area of the proximal NC joint, compared with 72.6% of combined cuneiform cartilage distally. The mean height of the deepest (dorsal-plantar) measurement of navicular articular cartilage was 18 ± 3 mm. The mean heights of the distal medial, middle, and lateral cuneiform articular facets were 15 ± 1 mm, 17 ± 2 mm, and 15 ± 2 mm, respectively.
UNASSIGNED: There is significant variation among the articular surfaces of the NC joint. Additionally, the central third of the navicular was calculated to lie in the inter-facet ridge between the medial and middle articular facets of the navicular.
UNASSIGNED: Surgeons may consider this study data when performing joint preparation for NC arthrodesis as cartilage was present to a mean depth of 18 mm at the NC joint. Additionally, this study demonstrates that the central third of the navicular, where most navicular stress fractures occur, lies in the interfacet ridge between the medial and middle articular facets of the navicular.

摘要：
■这项研究的目的是量化舟骨形（NC）关节的关节表面，以帮助临床医生更好地了解观察到的常见病理，例如舟骨应力性骨折和关节固定术骨不连。
■解剖了20个尸体NC关节，并切除了舟骨的关节软骨，中间,中间,和侧位楔形文字通过校准的数字成像软件进行定量。统计分析包括计算远端舟骨和近端楔形骨的平均软骨表面积尺寸。获得了舟骨上的长度测量值，以估计界面脊的地理位置。最后,关节表面的所有小平面都被描述为软骨或纤维成分的形状和位置。使用Studentt检验比较结果。
■舟骨软骨存在于近端NC关节表面积的75.4％以上，与远端楔形软骨的72.6％相比。舟骨关节软骨最深（足底背）测量的平均高度为18±3mm。远端内侧的平均高度，中间,外侧楔形关节小平面为15±1毫米，17±2mm,和15±2毫米，分别。
■NC关节的关节面之间存在显着变化。此外,舟骨的中央三分之一被计算为位于舟骨的内侧和中间关节面之间的面间脊。
■外科医生在进行NC关节固定术的关节准备时可能会考虑该研究数据，因为软骨在NC关节处的平均深度为18mm。此外,这项研究表明，舟骨的中部三分之一，大多数舟骨应力性骨折发生的地方，位于舟骨内侧和中间关节面之间的界面脊。
