Techniques of core decompression in the treatment of idiopathic avascular necrosis of the femoral head.
Arch Orthop Trauma Surg
December 2024
Department of Orthopaedic Surgery, Cleveland Clinic, Cleveland, OH, USA.
Core decompression was developed as a joint-preserving procedure for patients with early-stage osteonecrosis of the femoral head. Previous studies indicated a high success rate that outperforms nonoperative management of pre-collapse hips. The traditional single-tunnel core decompression technique uses a cannulated drill bit inserted into the lateral cortex of the proximal femur.

Objective: Histologically evaluate damage to rabbit femur after the creation of bicortical 1.5-mm-diameter holes using a standard surgical drill bit, an acrylic drill bit, and a Kirschner wire (K-wire).
Methods: 10 femora (5 pairs) from skeletally mature female intact New Zealand white rabbits were used.
Kinematic-kinetic compliant acetabular cup positioning based on preoperative motion tracking and musculoskeletal modeling for total hip arthroplasty.

Article Synopsis
- The invention of surgical robots improved the accuracy of component placement in total hip arthroplasty (THA), but a tailored preoperative planning method for cup alignment based on individual patient activity is still needed.
- This study developed a kinematic-kinetic compliant (KKC) method for positioning the acetabular cup, utilizing preoperative gait analysis, musculoskeletal modeling, and CT images to ensure optimal alignment and minimize complications like edgeloading and impingement.
- Validation of the musculoskeletal model showed that predicted muscle activations aligned with measured data, yet the recommended cup orientations sometimes fell outside the traditional safe zone, underscoring the need for personalized surgical planning.
Clinical outcomes of total hip arthroplasty after femoral neck fractures vs. osteoarthritis at one year follow up-A comparative, retrospective study.

General Surgery Clinic, Ovidius" University of Constanta, Constanta, Romania.
Purpose: The objective of the study is to determine if there was a difference in medical complications and in-hospital mortality among the patients who underwent THA for femoral neck fracture relative to same procedure for elective patients with coxarthrosis.
Methods: We compared characteristics and short-term outcomes during the rehabilitative postsurgical period. We included all patients older than 45 years who underwent THA for primary/secondary hip arthritis and displaced femoral neck fractures type Garden III and IV.
A latent bleeding complication in ipsilateral common femoral puncture involving delayed diagnosis: a case report.

Background: The trans femoral ipsilateral approach is often adopted for endovascular treatment (EVT) for better steerability of guidewires or better device deliverability. However, contrary to the trans femoral contralateral approach, ipsilateral antegrade puncture sometimes causes peculiar bleeding complications.
Case Presentation: A 76-year-old female underwent EVT for chronic occlusion of the left superficial femoral artery (SFA) via the ipsilateral antegrade approach.
