Summary
This study presents a novel central slip reconstruction technique using a V-shaped tendon graft for chronic Boutonniere deformity. The method shows promising results in improving joint range of motion.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Reconstructive Surgery
Background:
- Chronic Boutonniere deformity lacks a consensus-driven effective treatment.
- Existing treatments for Boutonniere deformity have variable outcomes.
Purpose of the Study:
- To describe a novel central slip reconstruction technique for chronic Boutonniere deformity.
- To evaluate the efficacy of autologous V-shaped tendon graft reconstruction.
Main Methods:
- Central slip reconstruction using an autologous "V" shaped tendon graft.
- Graft is folded and passed through a bone tunnel.
- Technique applied to patients with chronic, post-traumatic, and flexible Boutonniere deformity.
Main Results:
- Successful healing in all 3 patients.
- Average active range of motion: DIP joint 10-70°, PIP joint 15-90°, MCP joint 0-90°.
- Follow-up duration ranged from 4 to 5 years.
Conclusions:
- The described V-shaped tendon graft reconstruction is a straightforward technique.
- This method offers a viable treatment option for chronic Boutonniere deformity.
- The technique shows positive functional outcomes in improving joint mobility.

People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a car's tires and the surface of the road. If the driver presses the accelerator to the floor so that the tires spin without the car moving forward, there must be kinetic friction between the wheels and the road's surface. If the driver slowly presses the accelerator, causing the car to move forward, the tires roll without slipping. It is...

Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences frictional forces that cause slipping. This phenomenon can occur in various situations, such as when a tire rolls on a wet road or a ball rolls on a rough surface.
An object's rolling motion is characterized by its rotation around its axis, while linear motion refers to the object's translational motion along a surface. Frictional forces can...

Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...
