Fracture Reduction and Fixation – Principles, Types and Application

By Dr Arun Pal Singh

Fracture reduction treatment has evolved from its earlier days and now includes many modalities. This article describes the basic terms of reduction and fixation.

Closed Reduction

Closed reduction of the fracture means reducing the fracture fragments into acceptable anatomical position. After reduction has been achieved by manipulation and maneuvers, the alignment is generally maintained by plaster cast or implant.

Open Reduction

This means the fracture fragments are surgically opened, accessed and reduced. This opens the fracture hematoma and therefore term open is used for this kind of reduction.

Internal Fixation

It is a type of fracture fixation where the fragments are fixed by a gadget that is buried beneath the soft tissues and is not visible externally. Plating is a type of internal fixation.

External Fixation

In this kind of fixation, the fixing gadget is outside the soft tissue envelope and is visible to the naked eye. A tubular external fixator or Ilizarov external fixator is a type of external fixator.

Open Reduction and Internal Fixation

This term is used when reduction of the fracture is done by surgically exposing the fracture and then fixing the fracture with the required gadget. A compression plating is a typical example of open reduction and internal fixation.

Closed Fracture Reduction and Internal Fixation

This term is easier to understand if we understand the fact that the terms open or closed fracture reduction is in relation to the exposure of the fracture site.

So if a fracture can be reduced by manipulation and a gadget can be introduced and fixed without disturbing the fracture site, it would be called closed reduction and internal fixation.

Closed reduction because the fracture site was not opened to reduce the fracture and internal fixation because the gadget is buried under the soft tissue coverage.

This has been made possible by use of image intensifier which allows a view of structures during surgery.

A closed interlock nail is an example of closed reduction and internal fixation.

Erosive Osteoarthritis Causes and Treatment

An erosive osteoarthritis is a form of osteoarthritis with additional erosive or inflammatory phenomena though the patients are negative for rheumatoid factor negative. It most commonly affects the distal and proximal interphalangeal joints of the hand. The first carpometacarpal joint is affected less frequently. Joints of the foot are affected less commonly. Joints such as […]

Lateral Patellar Compression Syndrome

Lateral patellar compression syndrome is a disorder where there is an overload and increased pressure on the lateral facet of the patella due to tight lateral soft-tissue restraints. This results in the improper tracking of the patella and leads to excessive lateral tilt without excessive patellar mobility Earlier it was known as patellar compression syndrome or excessive […]

Ankle Fractures and Dislocations Injuries

Ankle fractures are actually groups fractures involving different parts of the region – the distal tibia, distal fibula, talus, and calcaneus. More often they are referred to fractures involving malleoli, distal tibia, and fibula. But ankle fractures also include the fractures of talus and calcaneum along with above-mentioned injuries. The group also includes fracture pattern […]

What is Evidence Based Orthopedics?

Evidence-based orthopedics is the application of principles of evidence-based medicine to the field of orthopedics. Because each of the medical specialty has its own set of challenges and unique applications, therefore, while the core principles remain the same, the methods and the applications must meet the need of each. What is Evidence-Based Medicine and What […]

Diabetic Lumbosacral Plexopathy

Diabetic Lumbosacral Plexopathy is a condition where proximal neuropathy occurs in nerves and often involves roots of lumbosacral plexus. It is also called lumbosacral radiculoplexus neuropathy. It is said to involve about 0.1% of diabetic and is seen more commonly in type 2 diabetes. Diabetic lumbosacral plexopathy results in pain, weakness of proximal muscles leading […]

Sacral Fractures – Presentation and Treatment

Sacral fractures are common in pelvic injuries and associated with 30-45% cases. About a quarter of sacral fractures are associated with neurologic injury. Sacral fractures are missed quite often, as often as 75% in patients without a neurological deficit and about half of those with the deficit. Neurologic injury associated with sacral fractures can range […]

Prosthetic Joint Infection

Prosthetic joint infection is a devastating complication of joint replacement surgery and occurs in1–3% of patients. Prosthetic joint infection can occur due to direct inoculation at the time of surgery or hematogenous spread of organisms to the prosthesis at a later time. One of the peculiarities of these infections is that the organism on attachment […]
