Self-Locking Screw01:16

Self-Locking Screw

A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Fascicle Arrangement in Skeletal Muscles01:25

Fascicle Arrangement in Skeletal Muscles

Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes.
The four primary types of muscle based on fascicle arrangement are:
Stress Concentrations in Circular Shafts01:18

Stress Concentrations in Circular Shafts

Consider the elastic torsion formula, which applies to a circular shaft with a consistent cross-section. This formula assumes that the shaft's ends are loaded with rigid plates firmly attached. However, in many cases, torques are applied to the shaft through mechanisms like flange couplings or gears, which are connected by keys inserted into keyways. This application method modifies the stress distribution near the point of torque application, causing it to deviate from the distributions...
Torsion of Noncircular Members01:16

Torsion of Noncircular Members

Circular shafts undergoing torsional stress maintain their cross-sectional integrity due to their axisymmetric nature. This symmetry ensures an even distribution of stress, allowing the shaft to withstand torsion without distorting. In contrast, square bars, lacking this axial symmetry, experience significant distortion across their cross-sections when subjected to torsion, with the exception of along their diagonals and at lines connecting midpoints. A detailed examination of a cubic element...

Summary

This study found no significant difference in Popeye deformity rates between forked eyelet and closed eyelet PEEK screws for biceps tenodesis. The choice of interference screw type does not impact this outcome in rotator cuff repair patients.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Sports Medicine

Background:

  • Biceps tenodesis is a common procedure following rotator cuff repair.
  • Popeye deformity is an objective indicator of successful biceps tenodesis.
  • Limited research compares different interference screw types for biceps tenodesis.

Purpose of the Study:

  • To compare the incidence of Popeye deformity using a polyether ether ketone (PEEK) forked eyelet tenodesis screw versus a traditional PEEK closed eyelet screw.
  • To evaluate the impact of interference screw design on outcomes of arthroscopic suprapectoral long head of biceps tenodesis.

Main Methods:

  • Retrospective analysis of 82 patients undergoing arthroscopic rotator cuff repair and biceps tenodesis.
  • Patients were divided into two groups based on tenodesis anchor: forked eyelet screw (Group I) or closed eyelet screw (Group II).
  • Follow-up was at least 1 year, comparing Popeye deformity rates between groups.

Main Results:

  • No significant differences in age, gender, or BMI between the groups.
  • Overall Popeye deformity rate was 8% (7/82 patients).
  • No significant difference in Popeye deformity occurrence between the forked eyelet (8.3%) and closed eyelet (10%) screw groups (P=.998).

Conclusions:

  • The incidence of Popeye deformity after arthroscopic biceps tenodesis is low.
  • The type of PEEK fixation anchor (forked eyelet vs. closed eyelet) does not significantly affect Popeye deformity rates.
  • Surgeons can select either screw type without compromising this specific outcome measure.
