On the pullout strength of human nasal hair

Materialia, 2021
Abstract This study investigates nasal hair-to-dermis detachment in humans, quantifying the pullout force required in adult males. While many studies have investigated the behavior and function of human body hair, little is known concerning the mechanical properties of human nasal hair or the strength of the hair-to-dermis attachment.

The Effect of Screw Insertion Angle and Thread Type on the Pullout Strength of Bone Screws in Normal and Osteoporotic Cancellous Bone Models

open access: yesMedical Engineering and Physics, 2010
Screw fixation can be extremely difficult to achieve in osteoporotic (OP) bone because of its low strength. This study determined how pullout strength is affected by placing different bone screws at varying angles in normal and OP bone models.

The Effect of the Trabecular Microstructure on the Pullout Strength of Suture Anchors [PDF]

open access: yesJournal of Biomechanics, 2010
This study investigates how the microstructural properties of trabecular bone affect suture anchor performance. Seven fresh-frozen humeri were tested for pullout strength with a 5mm Arthrex Corkscrew in the greater tuberosity, lesser tuberosity, and humeral head. Micro-computed tomography analysis was performed in the three regions of interest directly

Pullout strength of knotless suture anchors

Arthroscopy, 2005
Purpose Suture anchors are used consistently for repairs of soft tissues, especially around the glenohumeral joint. These anchors can be used either arthroscopically or in an open procedure to anatomically restore the labrum and capsular tissues to the glenoid after avulsion injuries (Bankart lesion).

Pedicle Screw Pullout Strength

Spine, 1993
This study was designed to correlate several parameters regarding pedicle screw bone/metal interface strength. The insertional torque measured during tapping and placement of pedicle screws was correlated with the bone mineral density of the vertebral body, the dimensions of the pedicle, the method of preparation of the pedicle, and the amount of load ...

Occipital Screw Pullout Strength

Spine, 1999
A three-group design with consistent pullout strength measures.To determine pullout strength of three fixation types (unicortical screws, bicortical screws, wires) and to investigate their correlation with respect to occipital morphology.A secured, multidirectional occipitocervical fusion requires internal fixation.
