Basic management of orthopedic emergencies

Basic management of orthopedic emergencies

1. Sprains: Since ligaments don't have a lot of blood flow, sprains can take up to 8 weeks to heal. Dismissing the injury as "just a sprain" should be avoided by doctors because doing so gives the patient the unreasonable expectation of a quick and complete recovery.

a) First and second-degree sprains: RICE, which stands for rest, immobilization, compression, and elevation, is the first line of treatment, along with analgesics or anti-inflammatory drugs. Typically, first- and second-degree sprains don't have any lasting effects.

b) Third-degree sprains: Patients with third-degree sprains should seek immediate orthopedic advice since these injuries might result in permanently reduced joint function. For several weeks, these sprains may need to be immobilized in circumferential casts, or they may need to be surgically repaired.


2. Fractures and dislocations

a) Stabilization of the patient: Although orthopedic emergencies are seldom life-threatening, concurrent life-threatening injuries may be present. Therefore, airway, breathing, and circulation (the ABCs) should be assessed first and appropriate measures are taken. Generally, in multiple trauma patients, airway, head, thorax, and abdominal injuries are treated before orthopedic injuries, although some orthopedic injuries (e.g., pelvic fractures of midshaft femur fracture) can significantly contribute to hemodynamic instability.

b) Reduction of swelling: Swelling occurs early after a fracture or dislocation and can increase the patient’s pain and delay the application of definitive immobilization.

Elevation of the extremity and application of cold compresses are effective measures for preventing the progression of swelling.

Potentially constricting jewelry on the injured extremity should be removed in anticipation of extremity swelling.

c) Temporary immobilization: The suspected fracture or dislocation should be immobilized early in the ED visit. Immobilization reduces the patient’s pain, diminishes the potential for damage to the neurovascular bundle, and reduces swelling and bleeding. Additionally, stabilization and immobilization facilitate patient transport, expedites the radiographic examination, and, in the case of fractures, reduce the chance of a sharp bone fragment puncturing the skin and converting a closed fracture to an open fracture.

For fractures, temporary immobilization is accomplished by splinting across the fracture and the joints proximal and distal to the fracture.

For dislocations, the joint may be immobilized using a splint or sling.

d) Pain control: Most patients with fractures or dislocations will become increasingly comfortable when the extremity is sufficiently immobilized.

e) Reduction is the process of restoring the bone or joint to its normal anatomic configuration: Early reduction decreases pain, may restore circulatory or nerve function, and prevents the progression of swelling.

— Generally, a radiograph of the bone or joint is obtained before the reduction of the fracture or dislocation.

Analgesics and sedatives are usually required for most reductions, which are generally accomplished by applying slow, steady, longitudinal traction.

A post-reduction radiograph is always needed to document the success of the procedure, determine if additional injuries are present, and assess the need for additional treatment.

f) Post-reduction immobilization: Reduced fractures and reduced dislocations must be immobilized before the patient is released from the ED (see Immobilization). 


Immobilization

1. Splints or circumferential casts are usually used to immobilize fractures: Splinting is less likely than circumferential casting to lead to pressure sores, circulatory compromise, and neurapraxia. After the swelling has decreased, a circumferential cast can be applied.

a) Patients with fractures that are not prone to complications and have only minimal swelling may be treated in the ED with circumferential casting.

b) Splints are usually made from plaster of Paris or fiberglass. Water causes an exothermic chemical reaction, which causes the material to harden over several minutes. During this process, the splint is molded along one side of the extremity, which is held in the appropriate position. Padding is placed between the skin and splint, and the splint is secured to the extremity with an elastic bandage wrapped circumferentially around the extremity and splint.

2. Immobilization dressings: In addition to splints, several dressings are commonly used in the ED. Examples include the shoulder sling, sling and swath, and knee immobilizer.

Transforming Emergency Care: The Story Behind Rigomo's Revolutionary PPMMP Course
Transforming Emergency Care: The Story Behind Rigomo's Revolutionary PPMMP Course
In the bustling corridors of a major hospital in Mumbai, Dr. Ayesha Khan felt the pulse of emergency medicine beating at a frantic pace. As a seasoned emergency room physician, she had seen it all — from the heartbreaking to the miraculous. Yet, despite her years of experience, Dr. Khan often felt that something was missing — a gap between the theoretical knowledge she had acquired and the real-world application of managing complex patient scenarios. It was during one critical incident, a complicated case of a diabetic emergency with multiple complications, that the idea for a comprehensive training program began to take shape.Dr. Khan observed that while her team was highly educated, they often hesitated, unsure of the best course of action when standard procedures didn’t align perfectly with the complexities presented by real-life cases. This observation was the seed that grew into the Practical Patient Management Program (PPMMP), developed in collaboration with Rigomo, a pioneer in healthcare education.The Genesis of PPMMPThe journey began with a simple question: How could healthcare professionals bridge the gap between theoretical learning and practical execution? The answer lay in creating a dynamic, interactive, and comprehensive training environment that mirrored real-life medical emergencies more closely than traditional classrooms or online courses ever could.Dr. Khan approached Rigomo with her vision, and together, they crafted a curriculum that was deeply rooted in the realities of medical practice. They decided to focus on a multi-faceted approach, incorporating simulations of emergency scenarios, step-by-step analytical techniques, and patient management strategies under pressure.What Sets PPMMP Apart?From the outset, the PPMMP was designed to be different. It wasn’t just about learning what to do; it was about understanding why, how, and when to do it. The course covers a wide range of emergencies — from metabolic crises like diabetes to respiratory emergencies and anaphylaxis. Each module is built around the latest research and clinical guidelines, ensuring that participants receive the most up-to-date information possible.However, the real magic of the PPMMP lies in its delivery. Recognizing the linguistic diversity of India, the entire course is offered in Hindi, making it accessible to a broader range of healthcare professionals. This decision has democratized access to advanced medical training, particularly benefiting those in rural or underserved areas.A Real-World ImpactOne of the most compelling testimonials comes from Dr. Manav Arora, a young doctor who enrolled in the PPMMP shortly after its launch. During an overnight shift, Dr. Arora faced a severe case of pulmonary embolism — a situation he had only read about in textbooks. Armed with knowledge and hands-on practice from the PPMMP, he was able to lead his team effectively, administer the right interventions, and save a life that night. Dr. Arora credits the PPMMP for his confidence and quick decision-making skills.Looking AheadToday, the PPMMP is not just a course but a movement. It’s about empowering doctors, nurses, and paramedics with the confidence to take bold, informed actions in critical situations. As healthcare continues to evolve, Rigomo is committed to updating the curriculum to include new findings, techniques, and technologies.The success story of the PPMMP is a testament to the power of innovative thinking in education and the profound impact it can have on healthcare delivery. It stands as a beacon for future endeavors in medical training, highlighting the crucial link between knowledge and action in saving lives.The Practical Patient Management Program has grown significantly since its inception, touching the lives of numerous healthcare professionals across India. The course’s success has encouraged other institutions to look towards similar models of integrated, practical training programs.
