Summary
Rotational instability after revision proximal interphalangeal joint arthroplasty is rare. A novel transosseous fixation technique through both phalanges offers a solution for recurrent prosthesis rotation in hyperlax patients.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Biomedical engineering
Background:
- Revision silicone arthroplasty of the proximal interphalangeal joint (PIPJ) can lead to rare but challenging rotational instability.
- This complication is particularly difficult to manage in young, hyperlax patients.
Purpose of the Study:
- To present a novel surgical technique for managing recurrent prosthesis rotation in PIPJ revision arthroplasty.
- To address the specific challenges posed by hyperlaxity in young patients.
Main Methods:
- A novel surgical technique involving transosseous fixation through both the proximal and distal phalanges is described.
- This method aims to provide secure fixation and prevent prosthesis rotation.
Main Results:
- The described technique offers a potential solution for recurrent prosthesis rotation.
- It specifically targets the management of instability in revision PIPJ arthroplasty, especially in challenging patient populations.
Conclusions:
- Transosseous fixation through both phalanges represents a promising novel approach for recurrent prosthesis rotation after PIPJ revision arthroplasty.
- This technique may improve outcomes for young, hyperlax patients experiencing this rare complication.

Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

In mechanics, when one observes a rigid body in rotational motion with constant angular acceleration, it is possible to establish equations for its rotational kinematics. This process resembles how linear kinematics are dealt with in simpler motion studies.
For instance, imagine a point A on a rigid body engaged in circular motion. The translational velocity of this particular point can be calculated by taking the time derivatives of the displacement equation, which essentially measures the...

By definition, a spherically symmetric body has the same moment of inertia about any axis passing through its center of mass. This situation changes if there is no spherical symmetry. Since most rigid bodies are not spherically symmetric, these require special treatment.
The relationship between the angular momentum of any rigid body and its angular velocity, both of which are vectors, involves the moment of inertia. The moment of inertia is a scalar quantity only for spherically symmetric...
