CT-guided infiltration of the ischiofemoral space in young patients with ischiofemoral impingement is an effective diagnostic tool.

Objectives: To present our technique of diagnostic CT-guided ischiofemoral space injection and report on pain response, complications, and associated imaging findings in young patients with ischiofemoral impingement (IFI).

Methods: Retrospective case series of patients with a clinical diagnosis of IFI that underwent CT-guided IFS injection with local anesthetic in a prone position with the feet in maximum internal rotation between 06/2019 and 04/2021. The response was evaluated using maximum subjective pain evaluation on a 0-10 visual analog scale (VAS) during a standardized pre- and postinterventional clinical examination.

Radiological predictors of outcomes in hip arthroscopy for femoroacetabular impingement.

Aims: Hip arthroscopy has gained prominence as a primary surgical intervention for symptomatic femoroacetabular impingement (FAI). This study aimed to identify radiological features, and their combinations, that predict the outcome of hip arthroscopy for FAI.

Methods: A prognostic cross-sectional cohort study was conducted involving patients from a single centre who underwent hip arthroscopy between January 2013 and April 2021.

Hip arthroscopy with initial access to the peripheral compartment for femoroacetabular impingement: midterm results from a large-scale patient cohort.

Background: Hip arthroscopy with initial access to the peripheral compartment could reduce the risk of iatrogenic injury to the labrum and cartilage; furthermore, it avoids the need for large capsulotomies with separate portals for peripheral and central (intra-articular) arthroscopy. Clinical results of the peripheral-compartment-first technique remain sparse, in contrast to those of conventional hip arthroscopy starting in the intra-articular central compartment. The purpose of this study was to assess outcome of hip arthroscopy with the peripheral-compartment-first technique, including complication rates, revision rates and patient-reported outcome scores.

Are degenerative findings detected on traction MR arthrography of the hip associated with failure of arthroscopic femoroacetabular impingement surgery?

Objectives: To identify preoperative degenerative features on traction MR arthrography associated with failure after arthroscopic femoroacetabular impingement (FAI) surgery.

Methods: Retrospective study including 102 patients (107 hips) undergoing traction magnetic resonance arthrography (MRA) of the hip at 1.5 T and subsequent hip arthroscopic FAI surgery performed (01/2016 to 02/2020) with complete follow-up.

Hip MRI in flexion abduction external rotation for assessment of the ischiofemoral interval in patients with hip pain-a feasibility study.

Objectives: To assess the feasibility of flexion-abduction-external rotation (FABER) magnetic resonance imaging (MRI) of the hip to visualize changes in the ischiofemoral interval and ability to provoke foveal excursion over the acetabular rim.

Methods: IRB-approved retrospective single-center study. Patients underwent non-contrast 1.

Can gadolinium contrast agents be replaced with saline for direct MR arthrography of the hip? A pilot study with arthroscopic comparison.

Objective: To compare image quality and diagnostic performance of preoperative direct hip magnetic resonance arthrography (MRA) performed with gadolinium contrast agent and saline solution.

Methods: IRB-approved retrospective study of 140 age and sex-matched symptomatic patients with femoroacetabular impingement, who either underwent intra-articular injection of 15-20 mL gadopentetate dimeglumine (GBCA), 2.0 mmol/L ("GBCA-MRA" group, n = 70), or 0.

High prevalence of hip lesions secondary to arthroscopic over- or undercorrection of femoroacetabular impingement in patients with postoperative pain.

Objectives: To compare the prevalence of pre- and postoperative osseous deformities and intra-articular lesions in patients with persistent pain following arthroscopic femoroacetabular impingement (FAI) correction and to identify imaging findings associated with progressive cartilage damage.

Methods: Retrospective study evaluating patients with hip pain following arthroscopic FAI correction between 2010 and 2018. Pre- and postoperative imaging studies were analyzed independently by two blinded readers for osseous deformities (cam-deformity, hip dysplasia, acetabular overcoverage, femoral torsion) and intra-articular lesions (chondro-labral damage, capsular lesions).

Usefulness of MR Arthrography of the Hip with and without leg Traction in Detection of Intra-articular Bodies.

Rationale And Objective: Although intra-articular bodies are a classic indication for MR arthrography and surgical removal, diagnostic studies are currently sparse. To assess the diagnostic performance of MR arthrography with and without leg traction in detection of intra-articular bodies in the hip joint.

Material And Methods: The institutional hip arthroscopy data base (2009-2016: 631 hips) was retrospectively reviewed.

[Experience with hybrid hip prosthesis walter-motorlet/poldi.].

In 1987-1992 at the Orthopaedic Clinic IPVZ 108 hybrid endoprostheses of the hip joint, type Walter-Motorlet/Poldi were implanted (non-cemented socket Walter-Motorlet, cemented shank Poldi). The authors submit evaluations of 75 endoprotheses made 2-7 years after surgery (mean follow-up period 3 and a half years). The mean age of the patients was 49 years (range 39-62 years), the most frequent preoperative diagnosis was secondary postdysplastic coxarthrosis (52%), other diagnoses were primary coxarthrosis (24%), idiopathic necrosis of the head of the femur (20%) and posttraumatic coxarthrosis (4%).

[Experience with Non-cemented Endoprostheses (Walter-Motorlet) of the Hip Joint.].

In 1987-1992 at the Orthopaedic Clinic of the IPVZ 61 non-cemented total endoprostheses of the hip joint Walter-Motorlet were implanted. The mean age of the patients is 50 years, the most frequent cause of operation is secondary postdysplastic arthritis of the hip joint (42.6%).

[Regeneration of bone after osteomyelitis of femur.].

The authors describe in their case report the case of regeneration of proximal femur in the patient with peracute hematogenous osteomyelitis. In a 13-year old patient proximal 20 cm of bone were gradually resected, while large sequesters were extirpated with the periost left untouched. After the healing of the acute infect there occurred a quick and quality regeneration of the resected bone.

[Results of surgical treatment of dislocation fractures of the ankle joint].

The authors have made evaluation of the surgical treatment of luxation fractures of the ankle in the period 1979-1987 in 105 patients (60 female, 45 male patients) in the age range from seventeen to eighty-one years, with the most frequent representation of the age group ranging from thirty-five to forty-five years. The group comprised 2,70 percent of fractures of type Weber A, 31.53 percent of fractures of type Weber B and 65.

[Care of chronic rupture of the fibular ligaments using the Weber method of reconstruction at the ILF].

After an inadequate conservative treatment of III-grade sprain of the ankle combined with the rupture of ligaments, these heal in prolongation which result in the chronic instability of the ankle joint. After the evaluation of the anamnesis and the objective examination the diagnosis is specified by comparative forced X-ray images in both projections. To substitute insufficient fibular ligaments we use a modification of the Weber method.
