Background:
The objective of this study (ClinicalTrials.gov ID: NCT03031015) is to compare the treatments of hand proximal phalanx shaft fractures with external-fixation technique using the combination of K-wires and bone-cement vs. open reduction and internal fixation technique using a miniature plate-and-screw system.
Methods:
A total of 107 patients (134 cases) were randomly allocated to group A (67 cases in 56 patients) and B (64 cases in 51 patients). Fingers in group A were treated with bone-cement K-wire fixation, and fingers in group B were treated using a plate-and-screw system.
Results:
Follow-ups lasted 2 years. In group A, active range of motion of proximal interphalangeal joint reached 93% ± 6.7% of the opposite fingers. In group B, the data reached 86% ± 14.4% of the opposite fingers. Based on total active motion scoring system, we obtained 21 excellent and 46 good results in group A; and 9 excellent, 50 good, and 5 fair results in group B. There was a significant difference with regards to the function of the fingers (p < 0.05).
Conclusions:
The bone-cement K-wire fixation may be another option for the treatment of shaft fractures of proximal phalanges. The minimally invasive technique allows early joint motion, resulting in minimal complications and good functional recovery.

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...

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
