Summary
The palmar proximal interphalangeal skin crease correlates with the joint axis of motion, aiding surgical planning for proximal interphalangeal joint injuries. Findings were consistent across age and handedness.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Radiology
Context:
- Proximal interphalangeal joint (PIPJ) injuries can lead to malalignment.
- External fixation methods, like Suzuki-type fixation, require precise anatomical axis preservation.
- Intraoperative X-rays are crucial for maintaining the phalanx's axis of motion.
Purpose:
- To determine the correlation between the palmar skin crease and the PIPJ axis.
- To enhance perioperative planning for PIPJ fracture fixation.
- To investigate the influence of sex, age, and handedness on this correlation.
Summary:
- A prospective study of 144 digits demonstrated a positive correlation between the palmar skin crease and the PIPJ axis of motion.
- Cobb angle measurements showed significant positive correlations for fingers 2-5.
- No significant differences were observed based on age or handedness; however, finger 2 Cobb angle was higher in females.
Impact:
- The palmar skin crease serves as a reliable indicator for the PIPJ's axis of motion.
- This finding supports improved accuracy in surgical fixation of PIPJ fractures.
- The study provides valuable anatomical data for orthopedic surgeons and hand specialists.

Consider a truss structure with frictionless joints fixed to a wall and roller support. If a force of 150 N is applied to joint A, the forces in each member of the truss can be determined using the method of joints.

1.1K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint. Consider a truss structure with two forces of 20 N and 10 N acting at joints C and D, respectively. The method of joints can be used to determine the forces FCB, FDC,...

01:18Deformations in a Symmetric Member in Bending
161
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...

01:23Knee Joint
1.5K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:14Bending of Curved Members - Strain Analysis
128
The mechanics of deformation in curved members, such as beams or arches, under bending moments, involve complex responses. When such a member, symmetric about the y-axis and shaped like a segment of a circle centered at point C, is subjected to equal and opposite forces, its curvature and surface lengths change significantly. This alteration results in the shift of the curvature's center from C to C', indicating a tighter curve.
