Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

Summary

This summary is machine-generated.

Schmid type II navicular fractures often heal well, especially with tension band plates. However, Schmid type III navicular fractures are severe injuries with poor outcomes, frequently requiring extensive reconstruction and potentially leading to foot stiffness.

Area of Science:

Orthopedic surgery
Trauma care
Radiology

Background:

Navicular fractures are complex injuries often associated with other foot trauma.
Understanding injury patterns and outcomes is crucial for effective treatment planning.

Purpose of the Study:

To evaluate injury characteristics and patient outcomes following navicular fractures.
To compare outcomes based on fracture classification and surgical intervention.

Main Methods:

Retrospective review of 39 navicular fractures using the Schmid classification.
Radiographic assessment for nonunion, malunion, and post-traumatic arthritis.
Analysis of surgical interventions including open reduction internal fixation with plates or screws, and talonavicular (TN) fusion.

Main Results:

Schmid type II fractures (18 cases) had a 67% healing rate without complications; tension band plates showed fewer complications than screws.
No avascular necrosis was observed.
Schmid type III fractures (21 cases) demonstrated poor radiographic outcomes, with 67% showing severe collapse or arthritis, often necessitating talonavicular (TN) fusion or triple arthrodesis.

Conclusions:

Schmid type II navicular body fractures, despite comminution, can heal well, with tension band plates potentially offering better stability.
Schmid type III navicular body fractures are devastating, frequently associated with severe foot trauma, and require complex reconstruction, often resulting in residual stiffness and the need for further surgery.
