Background: Transpedicular screw insertion has become widely accepted for the correction
of spinal deformity as well as degenerative and traumatic injury, but adoption of this …

Pedicle screws are typically used for fusion, percutaneous fixation, and means of gripping a
spinal segment. The screws act as a rigid and stable anchor points to bridge and connect …

Background Newer repair techniques of anterior cruciate ligament tears, including augmentation
with internal brace, have shown promising clinical results. Few biomechanical studies …

Study Design Analysis of insertion angle and bone density on the pedicle screw fixation
strength with a novel testing protocol that accounts for the articular processes. Objective To …

Background: Patellar tendon ruptures have routinely been repaired with transosseous suture
tunnels. The use of knotless suture anchors for repair has been suggested as an alternative…

Study Design Pedicle screw study. Objective The selection of pedicle screw parameters
usually involves the surgeon’s analysis of preoperative CT imaging along with anatomical …

Background Pull-out strength is a critical parameter to judge screw fixation in orthopaedic
implants. However, the insertion torque is the main feeling in the hand of a surgeon relating to …

Background Odontoid process fractures are among the most common in elderly cervical
spines. Their treatment often requires fixation, which may include use of implants anteriorly or …

Purpose Management of segmental rim defects and bone mineral density (BMD) loss in the
elderly prior to total hip replacement is unclear within classification systems for acetabular …

Vertebral compression fractures are a significant clinical issue with an annual incidence of
approximately 750,000 cases in the USA alone. Mechanical properties of vertebrae are …
