The lecture highlights the importance of early mobilization and physiotherapy to prevent complications like stiffness and deep vein thrombosis, ensuring a holistic approach to orthopedic care.
Key Insights
Fracture diagnosis integrates clinical findings with specific radiographic rules.
Accurate diagnosis is the precursor to management. Clinical signs include history of trauma, significant pain, localized tenderness (especially in scaphoid fractures), swelling from hematoma, deformity, crepitus, and loss of function. Standard X-ray protocols follow the 'Rule of Twos': two views (AP and Lateral), two joints (above and below the site), two sides (bilateral comparison), and two times (before and after reduction).
Open fractures are orthopedic emergencies requiring immediate debridement and specific antibiotic protocols.
Open fractures carry a high risk of infection (osteomyelitis) and hemorrhage. Emergency management involves early aggressive debridement to remove dead or devitalized tissue and foreign bodies. Antibiotic prophylaxis should cover gram-positive, gram-negative, and anaerobic organisms, typically using combinations like penicillin/aminoglycoside/metronidazole or third-generation cephalosporins. Wounds are often left open for secondary closure unless they are clean and treated within six hours.
Reduction techniques are tailored based on the fracture's displacement and stability.
Reduction involves bringing bone fragments back into alignment. It is not necessary for stable, non-displaced transverse or flat bone fractures. Closed reduction (Manipulation Under Anesthesia or MUA) often utilizes Ketamine or local lidocaine (with aspiration precautions). Open reduction (surgery) is indicated for failed closed reductions, intra-articular fractures, neurovascular compromise, and cases requiring internal fixation to ensure functional alignment and prevent osteoarthritis.
The selection of immobilization methods ranges from traditional casting to advanced internal fixation.
Maintenance of reduction is achieved through external splintage (POP or synthetic casts), traction (skin or skeletal), or fixation. Internal fixation using screws, plates, or intramedullary (IM) nails allows for accurate reduction and early mobilization, which is vital for preventing joint stiffness and DVT. External fixation with frames is preferred for contaminated compound fractures where internal devices are hazardous due to infection risk.
Rehabilitation is an essential, immediate component of the fracture treatment cycle.
Rehabilitation and physiotherapy should begin immediately after primary treatment. Early movement stimulates bone union and prevents the stiffness associated with prolonged immobilization. While a long bone shaft in an adult takes approximately 12 weeks to unite, children heal much faster. Effective rehabilitation ensures the patient regains full joint function and can return to normal occupations sooner, especially when stable internal fixation is utilized.

Diagnosis and Imaging Techniques
Identifying clinical features including pain, deformity, and tenderness.
The diagnosis starts with taking a history of trauma, which can range from major accidents to trivial injuries in pathological fractures. Key clinical signs include severe pain, localized tenderness (crucial for scaphoid fractures where X-rays may be initially clear), swelling due to fracture hematoma, visible deformity in displaced fractures, crepitus (grating sound between bone ends), loss of limb function, and potential neurovascular injury.
Adhering to the 'Rule of Twos' for standard X-ray imaging.
X-rays are mandatory to confirm the fracture's exact location and nature. The rules include: taking X-rays of two sides (bilateral for comparison), two views (Anteroposterior and Lateral), two joints (including joints above and below the fracture to avoid missing secondary injuries), and two times (before reduction for diagnosis and after reduction to check alignment).
Utilizing advanced imaging like CT and MRI for complex cases.
CT scans are often preferred over X-rays in modern hospitals for bony diseases and complex fractures. MRI is less helpful for primary fracture diagnosis but essential for delineating soft tissue injuries, CNS involvement, subtrochanteric disruptions, or fatigue fractures.
General Principles of Management
Prioritizing first aid following the ABCDE trauma protocol.
In serious trauma, the priority is Airway maintenance, Breathing, and Circulation (ABC). For the fracture specifically, management includes controlling external hemorrhage, covering open wounds with clean/sterile dressings, and immediate immobilization using splints (wood, sticks, or pillows) to relieve pain and prevent further vascular/neural damage.
Conducting clinical assessments including GCS and vascular checks.
In a hospital setting, doctors must check the state of circulation (pulse and BP), consciousness using the Glasgow Coma Scale (GCS) or the simpler AVPU scale (Alert, Verbal, Pain, Unresponsive), and identify any communicating wounds. Vital signs help rule out hypovolemic shock, and distal pulse checks ensure no major artery damage.
Providing supplementary treatments like analgesia and tetanus prophylaxis.
Fractures are highly painful, so immediate analgesia is required. IV fluids are necessary if bleeding is suspected. Antibiotics and Tetanus Toxoid (TT) are essential for open or compound fractures. In cases of significant contamination, prophylaxis against gas gangrene via debridement and antibiotics is critical.
Specific Treatment: Reduction and Maintenance
Understanding methods of closed and open fracture reduction.
Reduction is needed if fragments are displaced. Closed reduction involves manipulation under anesthesia (MUA), often using Ketamine for sedation. Open reduction involves surgery and is usually followed by internal fixation. The goal is to maintain function, prevent limb shortening, and ensure proper joint alignment to avoid long-term osteoarthritis.
Comparing Plaster of Paris (POP) with newer synthetic casting materials.
POP is cheap, versatile, and radiotranslucent but heavy and not waterproof. Newer materials like polythene or plastazote are lighter and stronger, allowing earlier weight-bearing and being waterproof, though they are more expensive and harder to mold perfectly.
Implementing traction as a method for reduction and immobilization.
Traction involves pulling the bone to align it. Skin traction is applied via adhesive tape (max 5kg), while skeletal traction uses pins through the bone (e.g., calcaneum or tibia) to allow greater force (up to 10kg). Specific types like Gallows/Bryant traction are used for children under two years old with femoral fractures.
Internal and External Fixation Techniques
Utilizing screws, plates, and intramedullary nails for internal fixation.
Internal fixation provides stable immobilization, allowing early patient mobility. Devices include cancellous screws for spongy bone, dynamic compression plates to squeeze bone ends together, and intramedullary (IM) nails (rods) for long bones like the femur, tibia, and humerus. IM nails are advantageous as they can often be inserted distant from the fracture site with minimal soft tissue dissection.
Applying external fixator frames for compound and comminuted fractures.
External fixators use pins inserted above and below the fracture connected to an external frame (monolateral or circular/Ilizarov). This is the preferred method for severely contaminated open fractures where internal hardware would risk deep infection, as it allows easy access for wound care.
Recognizing indications for surgery in pathological and joint fractures.
Surgery (ORIF) is essential for intra-articular fractures to ensure joint congruence, pathological fractures due to poor natural healing, elderly neck of femur fractures to prevent DVT from bed rest, and fractures associated with vascular injuries requiring repair.
Healing and Rehabilitation
Managing healing timelines based on bone type and patient age.
Adult long bone shaft fractures typically take 12 weeks to unite, while cancellous bone at the ends takes 6-8 weeks. In babies, this can be as fast as 2-3 weeks. Factors like blood supply and the rigidity of fixation significantly influence these timelines.
Emphasizing the vital role of physiotherapy to restore function.
Rehabilitation is the final, crucial step. It starts immediately to prevent muscle wasting and joint stiffness. Weight-bearing and exercises stimulate bone healing. Even after cast removal, a period of intensive physiotherapy is often required to overcome the 'uncomfortableness' and restore full range of motion.
