Diagnosis and Treatment of Fractures

Pain management and X-ray control

During the conservative treatment of fractures, regular X-ray monitoring plays a crucial role. This examination is performed repeatedly at various stages of therapy. The primary goal of such follow-up imaging is an objective assessment of the consolidation (fusion) process of the bone fragments and monitoring the proper formation of the callus.

The first and mandatory step in providing care is adequate pain management. Most commonly, the baseline technique is used: administration of a local anesthetic solution directly into the hematoma formed in the fracture area. For this purpose, solutions of procaine (novocaine), lidocaine, or trimecaine are traditionally used.

In situations where it is technically impossible to administer the drug directly into the injury site, or this method does not provide sufficient pain relief, specialists switch to alternative methods of anesthesia:

• Fascial compartment block — administration of an anesthetic into the fascial sheaths of the limb at a level above the fracture site.
• Nerve block — blocking impulse transmission along a nerve trunk.
• Nerve plexus block — silencing an entire plexus innervating the injured segment.
• General anesthesia (narcosis) — used in extreme cases when local anesthesia is critically insufficient.

Reduction of bone fragments: essence and approaches

The term reduction refers to a medical procedure aimed at eliminating the resulting displacement and achieving the most accurate apposition of bone structures strictly along the fracture line. Achieving the main treatment goal—the complete restoration of all normal functions of the injured limb—depends precisely on the meticulousness and accuracy of fragment apposition.

There are several main methods of reduction, among which manual reduction and reduction using a continuous traction system are most frequently used.

According to the time spent on eliminating the displacement, the techniques are classified into two large groups:

1. One-stage (acute) — imply rapid and complete apposition of bone fragments in a single procedure.
2. Gradual — displacement correction occurs smoothly over a certain period of time (this approach is most characteristic of the continuous traction method).

Specific traction methods and hardware reduction

Clinicians have various auxiliary devices and specialized apparatuses for bone reduction at their disposal, applied depending on the localization of the trauma.

Methods of so-called «soft» traction include:

• Glisson's loop. Used as a direct indication for cervical spine fractures. The design securely fixes the patient's head by the chin and occipital region. Traction is performed strictly along the longitudinal axis of the spine while the patient is in a supine position.
• Cuff traction. Used predominantly on the lower extremities. In this case, traction is applied via the foot or the ankle joint region.

Among hardware methods, the use of special devices stands out, for example, Sokolovsky's apparatus. A direct indication for its use is the need for reduction in forearm bone fractures. During the procedure, the patient is in a sitting position. The injured limb is rigidly fixed in the apparatus frame, after which vertical traction is applied with simultaneous counter-pressure exerted on the shoulder area.

Features of therapy for compression fractures of the spine

Treatment of spinal column injuries accompanied by compression requires a specific biomechanical approach. The main methods here are continuous traction and reclination. Reclination is a specific method of restoring the normal height of the damaged vertebral body through targeted extension.

The procedure technique is strictly regulated:

• The casualty is gently placed on their back on a specialized table.
• The patient's spine is given a position of sharp hyperextension in the injury zone.
• This position is not short-term — it must be maintained for several days.

The purpose of such a prolonged stay in the hyperextension position is that during this time, a smooth and effective elimination of the displacement of the broken vertebra's bone fragments occurs, which promotes its correct subsequent fusion.
