# Dynamic Compression Plating Versus Antegrade Intramedullary Nailing for the Treatment of OTA/AO 12-A Fractures: A Retrospective Cohort Study

## TL;DR

This study compares the cost and outcomes of two surgical methods for humerus fractures and finds that one method is more expensive but has similar recovery times.

## Contribution

The study provides new comparative data on cost-effectiveness and outcomes of AIMN versus plating for humerus diaphyseal fractures.

## Key findings

- AIMN had a higher average cost compared to plating methods.
- Drain placement likely increased length of stay in plating groups.
- No significant difference in surgical duration or recovery outcomes between methods.

## Abstract

Background: Fractures of the humerus diaphysis are common and often result from motor vehicle accidents (MVAs). Treatment methods range from nonoperative approaches to various operative techniques, including antegrade intramedullary nailing (AIMN) and dynamic compression plate (DCP) fixation. This study aimed to compare the cost effectiveness and outcomes of plating and nailing for humerus diaphyseal fractures.

Methods: A retrospective cohort study involving 59 cases of humerus diaphyseal OTA/AO 12-A fractures was conducted at King Saud Medical City (KSMC), a level I trauma center located in the center region in Riyadh, Saudi Arabia. Patients treated with AIMN, anterolateral plating, or posterior plating were included. Data on demographics, clinical parameters, radiographic healing, and costs were collected and analyzed.

Results: The average surgical duration was shorter in the AIMN group compared to the anterolateral and posterior plating groups but with no statistical significance (P > 0.05). The average length of stay (LOS) was shorter, and the change in hemoglobin levels was lower in the AIMN group when compared to other groups but without a statistically significant difference (P > 0.05). The average cost of AIMN was significantly higher than that of anterolateral and posterior plating groups (P < 0.0001).

Conclusion: While both nailing and plating procedures are options for treating OTA/AO 12-A fractures, AIMN carries a higher overall procedural cost. The practice of drain placement in our study population is likely the cause of the increased LOS in the plating groups. Relative additional analgesic requirements were associated with AIMN. Surgeons should consider meticulous hemostasis to avoid drain placement, which can decrease LOS, thus possibly decreasing unnecessary treatment costs of humerus shaft fractures.
