Normal histologic architecture of acetabular labrum, regarding presence of Free Nerve Endings (FNEs) and Nerve End Organs (NEOs) has been four times described. Nevertheless, elderly cadaveric specimens and individuals were recruited, leading to considerably high unreliability probability due to microscopic degenerative alterations. Aim of this paper is to analyze distribution pattern of FNEs and NEOs in acetabular labra of healthy middle-aged individuals, configuring thus more reliably acetabular labrum microscopic profile.
Six patients with middle age 52 ± 2.5 years were enrolled in this study. Injury of acetabular labrum and normal hip radiograph were present in all cases. Patients were all subjected to successful hip hemi-arthroplasty and derived acetabular labra were subsequently histologically processed and observed under a compound microscope.
FNEs and NEOs were detected in all specimens. All types of NEOs were identified, including Paccini, Golgi-Mazzoni, Ruffini and Krause corpuscles. FNEs and NEOs were both in ventral part and in chondral side of labrum predominantly detected.
FNEs and NEOs presence was greater in ventral side of labrum, being thus in partial agreement with previous studies results. Further study is required, in order to elucidate the exact acetabular labrum normal microscopic anatomy.

关于髋臼唇的正常组织学结构，包括游离神经末梢（FNE）和神经终末器官（NEO）的存在情况，已有四次相关描述。然而，此前研究招募的是老年尸体标本和个体，由于微观退行性改变，导致可靠性概率相当高。本文的目的是分析健康中年个体髋臼唇中FNE和NEO的分布模式，从而更可靠地构建髋臼唇的微观轮廓。
本研究纳入了6例年龄为52±2.5岁的患者。所有病例均存在髋臼唇损伤且髋关节X线片正常。患者均接受了成功的髋关节半关节置换术，随后对获取的髋臼唇进行组织学处理，并在复合显微镜下观察。
在所有标本中均检测到FNE和NEO。识别出了所有类型的NEO，包括帕西尼小体、高尔基-马佐尼小体、鲁菲尼小体和克劳泽小体。FNE和NEO主要在髋臼唇的腹侧部分和软骨侧被检测到。
FNE和NEO在髋臼唇腹侧的存在更为明显，因此与先前的研究结果部分一致。需要进一步研究以阐明髋臼唇确切的正常微观解剖结构。
