Does Pelvic Tilt Change After Periacetabular Osteotomy for Hip Dysplasia?

Background: The purpose of this study was to (1) evaluate preoperative pelvic tilt utilizing the sacro-femoral-pubic (SFP) angle on standing pelvic x-rays, and (2) determine if the SFP angle changes after a unilateral or bilateral PAO.

Methods: A retrospective review was conducted of PAOs performed by a single hip preservation surgeon from November 2018 to November 2023. Standing x-rays were reviewed at 4 time points: preoperative, subacute postoperative, 6-month follow-up, and 12-month follow-up.

A systematic approach to CT evaluation of non-arthritic hip pain.

Bone morphology has been increasingly recognized as a significant variable in the evaluation of non-arthritic hip pain in young adults. Increased availability and use of multidetector CT in this patient population has contributed to better characterization of the osseous structures compared to traditional radiographs. Femoral and acetabular version, sites of impingement, acetabular coverage, femoral head-neck morphology, and other structural abnormalities are increasingly identified with the use of CT scan.

Hip kinematics in healthy adults during gait and squatting: Sex differences and asymmetry revealed through dynamic biplane radiography.

There is a lack of data unaffected by soft tissue artifact describing bilateral symmetry and sex differences in hip kinematics in asymptomatic individuals during activities of daily living. This study aimed to identify sex-based differences and to quantify bilateral symmetry in continuous hip kinematics during walking and bodyweight squatting using biplane radiography. Twenty-four asymptomatic young adults (13 women, 11 men; age: 21.

Periacetabular osteotomy after failed hip arthroscopy demonstrates improved outcomes in a heterogenous patient population: a systematic review.

Purpose: To evaluate the literature on patients undergoing periacetabular osteotomy after failed hip arthroscopy (PAO-FHA) for (1) patient demographics and hip morphology, (2) changes in preoperative to postoperative patient-reported outcomes (PROs), and (3) PROs in comparison to primary periacetabular osteotomy (PAO) patients.

Methods: A systematic literature search of Pubmed, CINAHL/Medline, and cochrane databases was performed in accordance with PRISMA guidelines. The search phrase was "(periacetabular osteotomy or PAO or rotational osteotomy) and (hip arthroscopy or arthroscopic)".
