Intramedullary Kirschner Wire Fixation for Metatarsal Fractures: A Comprehensive Review of Treatment Outcomes

Metatarsal fractures pose significant challenges in orthopedic practice, necessitating effective treatment methods to ensure optimal patient outcomes. This comprehensive review focuses on intramedullary Kirschner wire fixation as a promising intervention for metatarsal fractures. Beginning with an overview of metatarsal fractures and the imperative for effective treatments, the review delves into intramedullary fixation's definition, historical background, advantages, and disadvantages. Indications for its use in metatarsal fractures are discussed, providing a foundation for understanding its application. The surgical technique section outlines critical aspects, including patient selection criteria and preoperative planning. Before presenting a detailed step-by-step procedure for intramedullary Kirschner wire fixation, anesthesia considerations are explored. Emphasizing precision, fluoroscopic guidance, and meticulous postoperative care, this section provides insights for surgeons and healthcare practitioners. Considerations for rehabilitation follow, addressing postoperative care, expected recovery timelines, and physical therapy recommendations. Early mobilization, weight-bearing guidelines, and a structured rehabilitation program play pivotal roles in recovery. In the conclusion, key findings are summarized, highlighting the efficacy of intramedullary Kirschner wire fixation, its advantages, and recommendations for clinical practice. Additionally, areas for future research are identified, guiding further exploration and refinement of this surgical approach. This review is valuable for clinicians, researchers, and healthcare practitioners involved in metatarsal fracture management, contributing to the evolution of treatment strategies and improving patient care.

Does Dressing Choice Affect Infection Rate in Percutaneous K-Wiring of the Hand and Wrist? - A Systematic Review

Background: Percutaneous Kirschner wire (K-wire) fixation of hand and wrist fractures is a common trauma procedure, yet there remains little consensus on the best management of wires postoperatively. If wire's ends are left external to the skin, it remains unknown which dressing regimen best reduces infection risk. We felt that a systematic review was required to assess the current consensus on this question within the published literature. Methods: An electronic search was carried out across multiple databases. Abstracts were screened by two independent reviewers against inclusion criteria and, where necessary, full texts were reviewed. Nine eligible papers were identified, and data regarding type of procedure, dressing choice and infection rate was extracted. Results: The included studies were widely heterogenous, and the standard of the evidence was, in general, poor. In most, dressing choice and infection incidence were not the primary intervention/outcome under study. Conclusions: Based on the available literature, insufficient evidence exists to establish one dressing choice as having a lower infection rate. This highlights the need for further high-quality evidence in this area. Level of Evidence: Level III (Therapeutic).

Comparative study of K-wire combined with screw vs. K-wire in the treatment of AO type B3.1 phalangeal fractures

PURPOSE

The purpose of this study was to introduce the surgical method of K-wire combined with screw in the treatment of Arbeitsgemeinschaftfür Osteosynthesefragen (AO) type B3.1 phalangeal fractures and to compare its clinical, radiological and functional outcomes with K-wire fixation.

METHODS

This was a retrospective comparative study. From January 2015 to February 2022, we treated 86 patients with AO type B3.1 phalangeal fractures. A total of 71 patients were finally included in the statistical analysis. Thirty-nine patients received K-wires combined with screw, and 32 patients received simple K-wires. The follow-up time was at least 6 months. Outcome measures included general information, operative time, total active motion (TAM), pinch strength, radiological union time, pain assessed by visual analog scale (VAS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, cost, and complications.

RESULTS

The follow-up time was 6-12 months, with an average of 7.9 months. All patients achieved clinical and radiological union. Compared with the K-wire fixation group, the TAM, radiological union time and VAS score of the K-wire combined with screw group had obvious advantages. Compared with the opposite healthy hand, the grip strength of the two groups was similar, and there was no significant difference in the QuickDASH score. The incidence rate of complications in the K-wire combined with screw group (2/39) was lower than that in the K-wire fixation group (7/32).

CONCLUSIONS

Compared with simple K-wire fixation, K-wire combined with screw in the treatment of AO type B3.1 phalangeal fractures is a safer and reliable surgical method. K-wire controls the rotation and plays a role similar to a "lock". The screw can exert pressure and fix it more firmly. It shortens the time of fracture healing and has a higher TAM and fewer postoperative complications.
