Hip joint sinking issues post-surgery can happen to anyone since the artificial hip stem inserted by doctors is not initially fully integrated with the patient’s bone after surgery. This results in the risk of the stem sinking over time. However, the risk of such problems can now be reduced by choosing a new type of hip stem that has a “collar”.
New Type of Hip Stem Reduces Post-Surgery Issues
Research by Dr. Panthakorn Panichkul, an orthopedic surgeon at Bangkok Hip and Knee Center, Bangkok International Hospital, and Dr. Hamilton, published in the Orthopedics medical journal, involving over 1,108 patients undergoing artificial hip replacement, found that using old or ‘collarless’ hip stems can increase the risk of patients needing revision surgery due to possible sinking of the hip stem post-surgery.
However, the development of a new type of hip stem, specially designed with a ‘collar’ (Collar), aids in better fixation of the artificial joint with the bone, enhancing the stability for long-term use. This can be used in conjunction with cobalt chromium or ceramic implants for improved and longer-lasting performance.
Benefits of the New Type of Hip Stem
- Reduces issues of hip sinking post-surgery
- Long service life of 15 – 20 years
- Full confidence in weight-bearing immediately
- Lower rate of revision surgery
- Suitable for use alongside muscle-sparing hip replacement surgery (new approach)
New Hip Stem with Collar in Modern Hip Replacement Surgery
If patients choose “muscle-sparing hip replacement surgery” which offers advantages like less pain, quicker recovery, it is essential to use the new type of hip stem. Post-surgery, patients can quickly return to normal life, bearing full weight immediately without the need for walking aids or crutches for an extended period. Using an old type of hip stem without a collar is riskier, as it may lead to implant loosening or sinking, necessitating revision surgery. However, using a new type of hip stem with a collar allows patients to bear weight confidently without the risk of the hip stem sinking.
Previously Operated? Resolve Issues with a Worry-Free New Surgery
For those who have had hip surgery and are concerned about hip sinking or dislocation, it is possible to undergo revision surgery. By seeking a detailed examination from a specialty doctor for potential loosening (Loosening) or bone fracture, a replacement with a new hip stem can be performed using the muscle-sparing hip replacement technique. This method involves a small surgical incision along the underwear line of just 3 – 4 inches, leading to less pain, faster recovery, and a swift return to normal walking post-surgery.
