Spinal Fusion Surgeries: Can Pedicle Screw Breach Cause Neurological Damage?

Spinal Fusion Surgery can help prevent back pain caused by degenerative disc disease, scoliosis, fractures, or infection of the spine. The vertebrae responsible for the motion that results in pain are joined and stabilized using wires, plates, or rods.
Pedicle screws are used to fix this instrumentation in place. They’re inserted into the anterior vertebrae via the bony lumbar pedicle.
Much like drilling a nail into a wall, inserting a pedicle screw can quickly go sideways. If the screw penetrates in the spinal canal, it could injure the nerves, and cause neurological damage.

Patients Often Don’t Lose Significant Weight after Total Knee Replacement Surgery

Excess body weight leads to osteoarthritis (4 times the risk in Women & 5 times the risk in Men, Anderson J and Fleson DT. Am.J.Epidemiol. 1988;128:179-189.) and causes cartilage loss in the joints, swelling, pain, and stiffness, limiting the mobility of the patient. It even renders them incapable of exercises that help lose weight.

Knee replacement surgeries are considered helpful in reducing joint pain and improves function, especially in people who find it difficult to sit or move because of bad joints. However, whether or not patients lose weight after Total Knee Replacement (TKR) procedures, has been a matter of conflict for long. (more…)

Taking Supplements Doesn’t Improve Bone Strength in Healthy Older Adults

Bone fractures can be caused by diseases like metastatic cancer, or trauma, like falling or hitting oneself. Both, vitamin D and calcium aren’t prescribed in the cases of pathologic fractures. However, with bones that are weak and calcium deficient, falling can cause severe injury.

Orthopedics and genuine bone-health concern are overshadowed by the prevalent idea that Vitamin D and Calcium supplements strengthen the bones and prevent fractures in people.

From a set of 33 clinical trials with 51,145 elderly participants (over 50 years of age), 14 compared the absolute risk difference between calcium supplements, no treatment, and placebo. 17 trials did the same with vitamin D in place of calcium.

The researcher discovered that there was little to no difference between the group which took supplements and the group which didn’t. Also, there was no clinically significant association between using supplements and risk reduction for fractures.

The study involved participants living in the community as opposed to those who stay at residential care facilities. The latter is more likely to be affected by osteoporosis, and more prone to falling accidents.

Total Hip Arthroplasty and Metabolic Diseases: Understanding the Complications

Among all metabolic diseases of the bone, like rickets, fibrous dysplasia, or osteomalacia, osteoporosis is the most common one and seen in elderly age group. If left unattended, such skeletal disorders can reduce bone density, cause structural deformities, pathological fractures and significantly limit the patient’s movement.

Treating conditions, like severe progressive arthritis, with Total Hip Arthroplasty ensures that the patient regains his/her freedom of movement. THA helps them deal with the chronic pain that renders them incapable of walking, moving, sitting, or climbing stairs with ease.

However, despite the soaring success rates of THA (over 95%,) there are possible complications, that shouldn’t be overlooked. In fact, understanding the complexities of the treatment, better equips the patient to admit themselves in the care of the  best orthopedician in Dubai or anywhere else, one who is well-suited to handle their case.

Possible Complications of Total Hip Arthroplasty

  • The hip implant can make squeaky noises because of metal-on-metal contact (0.5-10%)
  • Misaligned implants can loosen, cause pain, and hip dislocation (0.2-7%,  mostly within the first six months)
  • Hip dislocation because of weak muscle strength
  • Blood clots & pulmonary embolism (0.5-0.6%)
  • Infections, because of tissue allergies, diabetes, etc.
  • Fractures because of stem insertion (1%)
  • Nerve injury (0-3%)
  • Vascular injury (0.1-0.2%)

The chances of THA causing a serious side-effect issue is low. However, patients can further reduce the risk by choosing the most in-practice orthopedic clinic in Dubai, or anywhere in the world. THA is safest in the hands of a surgeon who has had enough practice.

Common orthopaedic conditions in children

  1. How common are these conditions in the UAE, do have any statistics?

Conditions such as in-toeing, flat feet, bowlegs and knock knee are rather common conditions affecting infants and children. In all of these cases, parents often anxiously rush to consult a specialist in order to check if their child’s limbs are normal. In most cases, these issues are not serious health concerns but a part of development.

  1. How frequently do you see these cases as a doctor and how do you usually deal with them?

In-toeing or pigeon toe is an extremely common condition found in children which they generally outgrow with age. Parents often consult us with the request to fix the deformity in their child’s feet. However children below the age of 8, with this condition do not require any specific treatment as they will outgrow it naturally.                               (more…)
