A new dynamic distraction external fixator effectively treats proximal interphalangeal joint (PIPJ) fracture-dislocations, leading to good fracture union and joint function recovery.
Area of Science:
- Orthopedics
- Hand Surgery
- Traumatology
Background:
- Proximal interphalangeal joint (PIPJ) fracture-dislocations are complex injuries.
- Effective treatment is crucial for restoring hand function.
Purpose of the Study:
- To evaluate the efficacy of a novel dynamic distraction external fixator for PIPJ fracture-dislocation.
Main Methods:
- Twenty patients with PIPJ fracture-dislocation were treated using the dynamic distraction external fixator.
- Outcomes assessed included Michigan Hand Outcome Questionnaire (MHQ) scores, union time, grip strength, and range of motion (ROM).
Main Results:
- All 20 patients achieved fracture union and joint reduction with a mean follow-up of 22 months.
- Excellent functional outcomes were observed, with high MHQ scores (mean 88.00), 92% of contralateral grip strength, and good ROM.
- No hardware complications or infections were reported.
Conclusions:
- The novel dynamic distraction external fixator demonstrates promising results for treating PIPJ fracture-dislocation.
- This technique facilitates fracture healing and joint stability, leading to favorable functional recovery.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
