Electromagnetic Device Tracking in Patients Undergoing CT-Guided Biopsy or Ablation

RATIONALE: Electromagnetic device tracking may help in planning diagnostic procedures and cancer treatment. PURPOSE: This clinical trial is studying electromagnetic device tracking to see...

Influence of an Capsular Tension Ring on the Rotation of an Intraocular Lens (Aspira®-aA Also Known as MC 6125 AS)

The purpose of this study is to observe the axial IOL rotation after surgery with a capsular tension ring (CTR) and a MC6125 AS IOL. At the end of surgery the orientation of the IOL is do...

Restoration of Leg Length, Offset, and Center of Rotation in Total Hip Replacement

The investigators aim to demonstrate the ability to accurately measure and restore leg length, offset, and center of rotation during a total hip replacement through a new technique that us...

Efficiency of Patellar Taping in Treatment of Patellofemoral Pain Syndrome

Patellar subluxation is a common disorder that may cause patellofemoral pain syndrome. The efficiency of patellar taping in the treatment of patellofemoral pain syndrome has been reported ...

The Difference of Angle of Femoral Component Rotation in TKA With Gap Balance and Measured Resection Technique

Gap balance type and measured resection type total knee arthroplasty (TKA) have different influence on the rotation of femoral component.In this study, the rotation of patients received di...

Internal femoral component rotation adversely influences load transfer in total knee arthroplasty: a cadaveric navigated study using the Verasense device.

Correct femoral component rotation at knee arthroplasty influences patellar tracking and may determine function at extremes of movement. Additionally, such malrotation may deleteriously influence flex...

A study of anatomy of distal femur pertaining to total knee replacement: an analysis, conclusions and recommendations.

Multiple landmarks including the transepicondylar axis (TEA), posterior condylar axis (PCA) and anterior trochlear line (TL) have been used to set up the femoral component rotation, but each is faced ...

Increased apical rotation in patients with severe aortic stenosis assessed by three-dimensional speckle tracking imaging.

Two-dimensional (2D) speckle tracking imaging (STI) is a non-invasive method used to assess subtle changes in left ventricular (LV) function such as strain and rotational dynamics. However, 2D methodo...

Gait deviations in transverse plane after SCFE in dependence on the femoral offset.

Residual deformity of the femoral head after slipped capital femoral epiphysis (SCFE) may be accompanied by a loss of femoral offset and lead to femoro-acetabular impingement (FAI), especially during ...

Quantitative Assessment of Femoral Head Perfusion Following Arthroscopic Femoral Osteochondroplasty: A Cadaveric Study.

Disruption of the arterial supply to the femoral head, and subsequent development of femoral head osteonecrosis, is of serious concern with intracapsular hip procedures. However, the effect of arthros...

Medical and Biotech [MESH] Definitions

A groin hernia occurring inferior to the inguinal ligament and medial to the FEMORAL VEIN and FEMORAL ARTERY. The femoral hernia sac has a small neck but may enlarge considerably when it enters the subcutaneous tissue of the thigh. It is caused by defects in the ABDOMINAL WALL.

The rotation of linearly polarized light as it passes through various media.

Intraoperative computer-assisted 3D navigation and guidance system generally used in neurosurgery for tracking surgical tools and localize them with respect to the patient's 3D anatomy. The pre-operative diagnostic scan is used as a reference and is transferred onto the operative field during surgery.

Disease involving the femoral nerve. The femoral nerve may be injured by ISCHEMIA (e.g., in association with DIABETIC NEUROPATHIES), nerve compression, trauma, COLLAGEN DISEASES, and other disease processes. Clinical features include MUSCLE WEAKNESS or PARALYSIS of hip flexion and knee extension, ATROPHY of the QUADRICEPS MUSCLE, reduced or absent patellar reflex, and impaired sensation over the anterior and medial thigh.

Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature also transferred to the new site. They are used in plastic surgery for filling a defect in a neighboring region. The concept includes pedicled flaps, rotation flaps, tube flaps, etc.
