“…Biomechanical contribution of acetabular labrum to hip joint stability is fundamental. Acetabular labrum increases, adhered to acetabular rim, surface area of acetabulum, enabling thus better articulation and providing greater stability 16,17 . Furthermore, it assists hip joint, supporting 1-2% of total load applied, as confirmed during normal walking simulation 18 .…”

Background: 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. Materials and methods: 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. Results: 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. Conclusion: 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. Level of evidence: IV.

Muscle activity and morphology in hip-related pain

Hip-related pain is common in young active people and is associated with intra-articular pathology and the pathogenesis of early onset osteoarthritis (OA). Hip-related pain can impact athletic participation and quality of life, as well as pose an ongoing financial burden to society through costs associated with long term management, including surgery. Improved knowledge of factors that contribute to the symptoms of hip-related pain and progression of joint degeneration are important. Muscles surrounding the hip are proposed to influence joint forces and dynamic stability, which can impact joint health and symptoms, yet little is known about muscle activity or morphology in hip-related pain. A greater understanding of the role that muscles play in hip-related pain may identify pathways for targeted treatment and primary prevention strategies in the future. A systematic review and meta-analysis (Study 1) was undertaken to ascertain the current best evidence regarding muscle morphology in hip-related pain. This review investigated all stages of articular hip pathology across the pathological continuum, identifying the presence of altered muscle morphology in moderate to advanced hip OA. The magnitude of difference in muscle size was not uniform across all muscles, suggesting they may be uniquely influenced by demand in articular pathology. Hypertrophy of deep anterior muscles, spanning the hip joint, in populations with compromised passive stability supports a hypothesis of increased activity to augment joint stability. Limited research has examined muscle activity in earlier stages of hip pathology, highlighting the need for further investigation of muscles surrounding the hip joint to clarify their role in hip-related pain. Iliocapsularis is a pericapsular muscle orientated over the anterior hip with direct attachments to the capsule. Because of its location and capsular insertions, it is theorised to play a dynamic role in joint stability which may be important in hip-related pain. Intramuscular electromyography (EMG) of Iliocapsularis has not been undertaken, due in part to its relative anonymity, and close proximity to the femoral neurovascular bundle posing technical 3.2.5
