The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

Clinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.

Subperiosteal circumferential connective tissue graft for vertical implant soft tissue augmentation

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertical implant soft tissue augmentation is indicated to optimize esthetic outcomes in cases of peri‐implant soft tissue deficiency or dehiscence, particularly when the peri‐implant mucosa is exposed during a full smile. This manuscript describes the use of a subperiosteal circumferential connective tissue graft (SC CTG) for ...

The Pullout Strength of Pedicle Screws Following Redirection After Lateral Wall Breach or End-plate Breach [PDF]

, 2016
Screw malposition, such as lateral wall breach or end-plate breach, is one of the main pitfalls of inserting pedicle screws. Methods: From 17 fresh spines 54 vertebrae were harvested.

Schematic drawing showing the designation of synthetic vertebrae instrumented with various pedicle screws.

, 2019
Different-sized screws were chosen and randomly implanted into each pedicle of the vertebrae by an experienced surgeon, 6.0 mm × 45 mm, 6.0 mm × 50 mm, and 6.5 mm × 45 mm screws were inserted sequentially into the semi-pedicle (left side of A, B, C) and ...

Finite element analysis of the pedicle screw in lumbar transpedicular dynamic stabilization that penetrates the lateral cortex of the vertebral pedicle

BMC Musculoskeletal Disorders
Background The mechanical stability of lumbar transpedicular dynamic stabilization (LTDS) was determined by simulating the degree to which the pedicle screws penetrated the lateral pedicle cortex.

A Biomechanical Comparison of Expansive Pedicle Screws for Severe Osteoporosis: The Effects of Screw Design and Cement Augmentation. [PDF]

PLoS ONE, 2015
Expansive pedicle screws significantly improve fixation strength in osteoporotic spines. However, the previous literature does not adequately address the effects of the number of lengthwise slits and the extent of screw expansion on the strength of the ...

Biologic gracilis augmentation with iliotibial band enhances recovery and lowers complications in ACL reconstruction compared with hamstring plus lateral tenodesis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the iliotibial band autograft biologically augmented with gracilis (ITBAG) technique with a hamstring tendon autograft combined with extra‐articular lateral tenodesis using fascia lata (HT‐LET), in terms of (1) return‐to‐sport rates, (2) patient‐reported functional outcomes and (3) complication rates.

Stability of Pedicle Screws After Kyphoplasty Augmentation

, 2006
Objective: The goal of this cadaver study was to compare the stability of pedicle screws after implantation in soft or cured kyphoplasty cement. Methods: Pedicle screws were inserted in a total of 30 thoracolumbar vertebrae of 10 different human ...
