Survival Analysis and Failure Modes of Total Hip Arthroplasty Using a Cemented Semi-Retentive Acetabular Cup.

To reduce the incidence of total hip revisions, there have been continuous efforts to enhance prosthetic materials and designs to optimize implant survival. A primary implant with a constrained acetabular component is often used to minimize the risk of dislocations even though this approach has some drawbacks as reported in the literature. To address these concerns, this study aimed to assess the survivorship and dislocation rate of a semi-retentive cemented acetabular cup when used as a primary implant.

Evaluation of Total Hip Arthroplasty Performed from a Lateral Approach as Optimal Treatment for Femoral Neck Fractures in Elderly, Active Patients.

Background: The aim of the study was to evaluate total hip arthroplasty in terms of clinical and functional outcomes, rate of complications and hospitalization, as a treatment of choice for displaced femoral neck fractures.

Materials And Methods: We retrospectively reviewed the data of 526 patients with THA operated on in our department between January 2017 and December 2021. Clinical examinations, functional outcome assessment and radiographic evaluation were performed during follow-up.

Primary bone leiomyosarcoma of distal femur: case report and literature review.

We present the case of a 58-year-old patient presented with a spontaneous right supracondylar fracture. The initial bone biopsy, highlighted the defining histopathological (HP) elements for a leiomyosarcoma (LMS), initially considered a metastasis. The complex imaging examinations did not reveal another tumor, so the final diagnosis was primary bone LMS.

Common peroneal nerve palsy after primary total hip arthroplasty.

Purpose: The study wants to evaluate the incidence, the clinical evolution, and treatment of common peroneal nerve (CPN) palsy after primary total hip arthroplasty.

Methods: Our clinical prospective study was made between January 2016 and December 2020. The study group comprised 1240 total hip replacements over a period of five years.

Malignant Bone Tumors Diagnosis Using Magnetic Resonance Imaging Based on Deep Learning Algorithms.

: Malignant bone tumors represent a major problem due to their aggressiveness and low survival rate. One of the determining factors for improving vital and functional prognosis is the shortening of the time between the onset of symptoms and the moment when treatment starts. The objective of the study is to predict the malignancy of a bone tumor from magnetic resonance imaging (MRI) using deep learning algorithms.

Transfemoral Approach in Revision Hip Arthroplasty: A Prospective Analysis of 36 Cases: Radiological and Functional Results at a Minimum 2 Years Follow-up.

: One of the most difficult aspects of hip revision is to remove the stem from the femoral canal with or without cement while maintaining the maximal amount of bone stock to obtain the best possible press-fit of the revision prosthesis. The transfemoral approach ensures direct access to the medullary canal so that the content removal is completed under direct control, while protecting the bone. This type of approach is particularly efficient for special conditions, such as deformation of the proximal femoral region, broken stems, or the presence of cement over a long distance distal to the prosthesis.

Arthroscopic Repair in Tibial Spine Avulsion Fractures Using Polyethylene Terephthalate Suture: Good to Excellent Results in Pediatric Patients.

Background: The objective of the arthroscopic treatment in tibial spine avulsion fractures (TSAF) is to achieve firm reduction and strong internal fixation while still having the patient undergo a minimally invasive procedure.

Material And Methods: The study was performed on 12 young patients with avulsion fracture of the anterior tibial spine. All 12 patients had type 3 Modified Meyers and McKeever fractures.
