Fracture Care
A bone fracture is a medical condition in which a bone is cracked or broken. It is a break in the continuity of the bone. While many fractures are the result of high force impact or stress, bone fracture can also occur because of certain medical conditions that weaken the bones, such as osteoporosis.
The word “Fracture” implies a broken bone. A bone may get fractured completely or partially and it is caused commonly from trauma due to fall, motor vehicle accident or sports. Thinning of the bone due to osteoporosis in the elderly can cause the bone to break easily. Overuse injuries are common cause of stress fractures in athletes.
Types of fractures include:
- Simple fractures in which the fractured pieces of bone are well aligned and stable.
- Unstable fractures are those in which fragments of the broken bone are misaligned and displaced.
- Open (compound) fractures are severe fractures in which the broken bones cut through the skin. This type of fracture is more prone to infection and requires immediate medical attention.
- Greenstick fractures is a unique fracture in children that involves bending of one side of the bone without any break in the bone.
Fracture Healing
Our body reacts to a fracture by protecting the injured area with a blood clot and callus or fibrous tissue. Bone cells begin forming on the either side of the fracture line. These cells grow towards each other and thus close the fracture.
Medical Therapy
The objective of early fracture management is to control bleeding, prevent ischemic injury (bone death) and to remove sources of infection such as foreign bodies and dead tissues. The next step in fracture management is the reduction of the fracture and its maintenance. It is important to ensure that the involved part of the body returns to its function after fracture heals. To achieve this, maintenance of fracture reduction with immobilization technique is done by either non-operative or surgical method.
Non-operative (closed) therapy comprises of casting and traction (skin and skeletal traction).
- Casting
Closed reduction is done for any fracture that is displaced, shortened, or angulated. Splints and casts made up of fiberglass or plaster of Paris material are used to immobilize the limb. - Traction
Traction method is used for the management of fractures and dislocations that cannot be treated by casting. There are two methods of traction namely, skin traction and skeletal traction.
Skin traction involves attachment of traction tapes to the skin of the limb segment below the fracture. In skeletal traction, a pin is inserted through the bone distal to the fracture. Weights will be applied to this pin, and the patient is placed in an apparatus that facilitates traction. This method is most commonly used for fractures of the thighbone.
Surgical Therapy
- Open Reduction and Internal Fixation (ORIF)
This is a surgical procedure in which the fracture site is adequately exposed and reduction of fracture is done. Internal fixation is done with devices such as Kirschner wires, plates and screws, and intramedullary nails. - External fixation
External fixation is a procedure in which the fracture stabilization is done at a distance from the site of fracture. It helps to maintain bone length and alignment without casting.
External fixation is performed in the following conditions:
- Open fractures with soft-tissue involvement
- Burns and soft tissue injuries
- Pelvic fractures
- Comminuted and unstable fractures
- Fractures having bony deficits
- Limb-lengthening procedures
- Fractures with infection or non-union
Rehabilitation
Fractures may take several weeks to months to heal completely. You should limit your activities even after the removal of cast or brace so that the bone becomes solid enough to bear the stress. Rehabilitation program involves exercises and gradual increase in activity levels until the process of healing is complete.
Knee Fracture
Knee Fracture
A fracture is a condition in which there is a break in the continuity of the bone. In younger individuals, these fractures are caused from high energy injuries, as from a motor vehicle accident. In older people, the most common cause is weak and fragile bone.
Shoulder Fracture
Shoulder Fracture
The clavicle and end of the humerus closest to the shoulder are the bones that usually get fractured. The scapula on the other hand is not easily fractured because of its protective cover by the surrounding muscles and chest tissue.
Wrist Fracture
Wrist Fracture
The wrist is comprised of two bones in the forearm, the radius and ulna, and eight tiny carpal bones in the palm. The bones meet to form multiple large and small joints. A wrist fracture refers to a break in one or more of these bones.
Ankle Fracture
Ankle Fracture
An ankle fracture is a painful condition where there is a break in one or more bones forming the ankle joint. The ankle joint is stabilized by different ligaments and other soft tissues, which may also be injured during an ankle fracture.
Hip Fracture
Hip Fracture
Hip fracture is a break that occurs near the hip in the upper part of the femur or thighbone. The thighbone has two bony processes on the upper part - the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thighbone. Hip fractures can occur either due to a break in the femoral neck, in the area between the greater and lesser trochanter or below the lesser trochanter.
