Editorial Commentary: Looking Past the Hip Joint—The Role of Pelvic Incidence in Femoroacetabular Impingement

Abstract

In a retrospective comparative study, pelvic incidence was significantly less in patients with symptomatic femoroacetabular impingement (FAI), with a significant difference in FAI subgroups compared with asymptomatic volunteers. This finding may help to explain the existence of asymptomatic FAI morphology and highlight the importance of thorough assessment of the patient with hip pain.

Spinopelvic Parameters Do Not Influence Outcomes Following Primary Hip Arthroscopy for the Treatment of Femoroacetabular Impingement Syndrome

“… 19 Moreover, increasing PT has been shown to result in dynamic anteversion of the acetabulum, providing a functional advantage for hip internal rotation when going from standing to sitting. 42 , 43 , 44 As such, patients with a decreased PI are unable to compensate for their hip pathoanatomy due to the inability to alter PT, effectively decreasing dynamic acetabular anteversion, limiting hip internal rotation, and leading to hip impingement with flexion. 19 , 43 , 45 , 45 Such findings have been corroborated in clinically studies.…”

Unravelling the hip-spine dilemma from the CHECK-cohort: is sagittal pelvic morphology linked to radiographic signs of femoroacetabular impingement?

“…11,12 Patients with relatively low PI or with lumbar degeneration have limited posterior PT when changing from standing to sitting position and often have flattened lordosis. 13 Anteroposterior pelvic rotations around the hip axis will have important consequences for the biomechanical loading and range of motion of the hips. Low PI and PT limits the anterior 'opening' of the acetabular cavities when changing from standing to sitting, with a higher likelihood of impingement.…”

Editorial Commentary: Platelet-Rich Plasma Versus Surgery for Hip Greater Trochanteric Pain Syndrome—Systematic Reviews Made Difficult by the Use of Vague Terms

“…When writing my previous Editorial Commentaries, my focus was on the merits of a study and its impact on my clinical practice. [2][3][4][5][6][7][8][9][10][11] GTPS is a very common problem, regularly encountered by the general orthopaedic surgeon. 12 However, with all due respect to the authors of this systematic review, there is little impact on my clinical practice this time.…”
