Introduction[edit | edit source]
Kyphoplasty KP is a relatively new procedure that was first performed in California in 1998.  It is a minimally invasive percutaneous procedure that involves the insertion of an inflatable bone tamp into the fractured vertebral body under fluoroscopic guidance. The bone tamp is then inflated, elevating the endplates and restoring the vertebral body toward its original height. The procedure has been shown to speed up the treatment and recovery period of vertebral compression fractures. It has the added benefit of addressing kyphotic deformity as well as pain, unlike vertebroplasty that only addresses pain. Indications for kyphoplasty include painful or progressive osteoporotic and osteolytic vertebral compression fractures that do not compromise the spinal canal based on the level of pain and the percentage of vertebral collapse. If a patient rates his/her pain as being greater than 5 out of 10 (when 10 equals worst pain imaginable and 0 equals no pain) or the vertebral bodies are collapsed more than 40%, then kyphoplasty or vertebroplasty is indicated as an initial intervention. Conservative treatment has been questioned as it can take months to resolve and requires an extended period of rest which can lead to a further decrease in bone density. In most cases, kyphoplasty can eliminate the need for complex surgical fixation, especially where the bones are osteoporotic. However, if there is compromise neurological compromise kyphoplasty is not indicated.
Procedure[edit | edit source]
Unlike vertebroplasty VP, a balloon is inserted percutaneously into the vertebral body and inflated before the thick polymethylmethacrylate (PMMA) is injected in under low pressure into the cavity of the body. The bone tamp is then deflated and removed. Kyphoplasty has been shown to provide significant pain relief as well as a substantial improvement in the height of the collapsed vertebral body and has been found to reduce the spinal kyphosis.This video below shows the difference between the KP and VP.
Clinical Presentation[edit | edit source]
The onset of sudden, severe back pain, that worsens on standing or walking but relieves when lying down can often be mistaken for muscle strain but if there is a loss of movement and pain when bending or twisting coupled with a loss of height, deformity of the spine - "hunchback" shape then a fracture may be suspected. In most cases the mechanism of injury is the same as a back strain and can be caused by doing every day tasks such as lifting, bending to pick something up from the floor, or a simple slip or missing a step. Another warning sign that it could be something more serious is the age of the client, people over the age of 50 and in particular women are at risk of osteoporosis and therefore more susceptible to a serious injury like a fracture.
Diagnostic Tests[edit | edit source]
It is important to correctly assess a patient who presents with spinal pain of traumatic or atraumatic origin that is not responding to conservative treatment, particularly if the patient falls under the risk category for osteoporosis. The most common tests are:
- Radiography - X-rays are usually the first diagnostic test performed as they are inexpensive. A lateral X-ray of the thoracic or lumbar spine can often identify a fracture and reveal any loss of height or misalignment of the spine.
- Computed Tomography (CT) scan - provides greater detail of bony anatomy and can reveal loss of height, fragment retropulsion, and any compromise of the spinal
- Magnetic Resonance Imaging (MRI) - This is more expensive but can reveal whether the fracture is acute (by the presence of bony oedema) and also if there is compromise of the neurological system.
- Bone Scintigraphy - a nuclear medicine imaging technique of the bone that is used to diagnose bone conditions and disorders such as fracture, infection, and cancer
Complications[edit | edit source]
Kyphoplasty is the least invasive intervention that is effective in the treatment of VCF that didn't respond to conservative intervention, it shows a rapid pain relief and improvement in pain on VAS, quality of life, and pulmonary function.
- Extravertebral leakage of the cement, the leakage may happen through the cracks of the vertebrae. this leakage of cement may into the spinal canal causing spinal canal stenosis which isn't common to happen and less common on kyphoplasty than vertebroplasty or may cause pulmonary embolism that rarely requires immediate intervention its symptoms vary from mild dyspnoea which is usually asymptomatic to serious symptomatic complications that will need urgent surgery to remove the cement. Cement leakage is less common in kyphoplasty about 9% than in vertebroplasty about 41%.
- Secondary fracture to the vertebrae above and below and maybe secondary due to the leakage of cement in the intervertebral disc, secondary most common in kyphoplasty.
- It has a higher risk of cardiac mortality than vertebroplasty.
- Infected spondylitis with epidural abscess at the operated vertebrae site.
- Superficial wound infection as in any surgical intervention was reported in a study within 1 0 days after KP.
Physiotherapy Management[edit | edit source]
Physiotherapy is indicated both pre and post-op. Prior to kyphoplasty the emphasis is on pain relief and preventing secondary complications such as progressive immobility and weakness. The following interventions are recommended for pain relief prior to the procedure:
- Analgesic medication
- Gentle exercises and advice on activities of daily living
Physiotherapists should also give advice to prevent further injury, especially when recommending exercises. Patients should be advised to avoid flexion exercises such as crunches and situps. However, Axial back extension strengthening exercises should be included in the programme, in accordance with the patient's pain tolerance. Weight bearing exercises should be included to minimize the effects of osteoporosis, however, aquatic exercises and balance training are also beneficial.
Any patient with diagnosed osteopenia or osteoporosis should be on anti-osteoporotic medications, including second-generation bisphosphonates, as well as (daily) with 1500 mg of elemental calcium and 400 IU of vitamin D.
Most Kyphoplasty procedures are performed on an outpatient basis unless the patient has comorbidities requiring a short inpatient stay. Post-op treatment should be geared towards home safety training if the patient is at high risk for fall (Berg Balance Scale>40), pain management, and transfer training. Rehabilitation at this stage should focus not only on recovery but must also prevention. The following modalities should be included in the programme with a gradual increase in intensity depending on the patient's tolerance.
- Strengthening Exercises - particularly of the back extensors can assist not only with pain management and with improving posture
- Weightbearing Exercises - should be included into the programme as mechanical loading will stimulate osteogenesis (Wolff’s law), improving bone quality and reducing the risk of (or worsening) osteoporosis.
- Stretching - Care needs to be taken not to overstretch, especially spinal flexion, as this may alter the protective mechanisms against back pain.
- Pain Management - advice on the use of heat and ice
- Advice and transfer practice - teaching the client how to move from one position to another may help to minimise unnecessary load on the spine
- Manual handling training and activities of daily living - correct techniques on lifting and daily tasks can help reduce the load on the spine and other joints
- Balance and Proprioception Training - This is especially beneficial for clients who are at risk of falling
- Posture Re-education - adopting correct posture at rest and when active can help to reduce the stress on the spine, muscles, and ligaments.
At each step of the programme the patient should be treated like an individual and their level of pain, function and lifestyle should be taken into account. Close monitoring is necessary to ensure that the programme is progressed in accordance with the patient's status and needs.
Outcome Measures[edit | edit source]
Outcome measures can help assess a patient's current status and function and monitor their progress. Below are some of the most common used to determine the need for this procedure and also to predict and review outcomes of the surgery and subsequent interventions.
- Pain Visual Analogue Scale (VAS) - Measures Pain intensity
- European Vertebral Osteoporosis Study Questionnaire (EVOS) - Measures health impact, back pain and functional capacity of vertebral compression fractures
- Oswestry Disability Index (ODI) - Measures back function, physical ability, mobility, pain, sexual function
- Short Form Survvey (SF-36) -Measures Overall quality of health: (including physical and mental health)
- Roland Morris Disability Questionnaire (RMDQ) - Measures back function, physical ability, mobility, pain
