The objective of this study was to determine whether glenoid morphology correlates with anterosuperior labral variation.
Eighty-eight direct shoulder magnetic resonance arthrograms were retrospectively reviewed. Sagittal oblique images were assessed for the presence or absence of anterosuperior glenoid concavity. Evaluation of axial images was performed, separately classifying the anterosuperior labrum into 1 of 4 categories: no variation, diminutive labrum, sublabral foramen, or Buford complex.
In 88 shoulders, there were 13 notched glenoids (15%). In this group, 3 (23%) had a Buford complex, 2 (15%) had a sublabral foramen, and 4 (31%) had a diminutive labrum. There were 75 ovoid glenoids (85%). In this group, 3 (4%) had a Buford complex, 8 (11%) had a sublabral foramen, and 7 (9%) had a diminutive labrum. There was a significant association (P = 0.001) between notched glenoid morphology and developmental variation of the anterosuperior labrum.
The presence of anterior glenoid concavity is significantly associated with overlying labral variation, which may be of use in discriminating labral pathology from developmental variation.
本研究的目的是确定肩胛盂形态是否与盂唇前上部分的变异相关。
回顾性分析88例直接肩关节磁共振关节造影。在矢状斜位图像上评估盂唇前上部分有无凹陷。对轴位图像进行评估，将盂唇前上部分分为4类中的1类：无变异、盂唇减小、盂唇下孔或布福德复合体。
88个肩关节中，有13个肩胛盂有切迹（15%）。在该组中，3个（23%）有布福德复合体，2个（15%）有盂唇下孔，4个（31%）盂唇减小。有75个卵圆形肩胛盂（85%）。在该组中，3个（4%）有布福德复合体，8个（11%）有盂唇下孔，7个（9%）盂唇减小。肩胛盂切迹形态与盂唇前上部分发育变异之间存在显著相关性（P = 0.001）。
肩胛盂前侧凹陷的存在与上方盂唇变异显著相关，这可能有助于区分盂唇病变与发育变异。
