Our Summary

This study aimed to determine the amount and direction of force used by expert surgeons during wrist arthroscopy (a minimally invasive surgical procedure on the wrist). The researchers created a system where a cadaver wrist was attached to a 3D platform that could measure the forces applied to the wrist. Six experienced wrist surgeons were asked to perform two tasks: introducing a camera and navigating through the wrist to visualize five different anatomical structures. The forces and directions used were recorded.

The results showed different force patterns for each of the five anatomical landmarks. The median force applied during navigation was 3.8 Newtons (N), with a maximum force of 7.3 N. The direction of force varied depending on the task.

These findings can be used to set standards for training new surgeons, providing them with feedback on their performance. This will help improve the objectivity of skills assessments in surgery.

Doctor’s Tip

Additionally, a doctor may advise a patient undergoing wrist arthroscopy to follow post-operative care instructions carefully, including keeping the wrist elevated, applying ice as needed, and performing recommended exercises to aid in recovery and rehabilitation. It is important for the patient to communicate any concerns or changes in symptoms to their healthcare provider for proper management and monitoring of the healing process.

Suitable For

Patients who may be recommended for wrist arthroscopy include those with wrist pain, stiffness, swelling, or limited range of motion that has not improved with non-surgical treatments such as rest, physical therapy, or medication. Wrist arthroscopy can be used to diagnose and treat a variety of conditions such as ligament tears, cartilage injuries, ganglion cysts, arthritis, and wrist fractures. It is typically recommended for patients who have not responded to conservative treatments and who may benefit from a minimally invasive surgical approach to address their wrist issues.

Timeline

Before wrist arthroscopy:

  1. Patient presents with wrist pain or injury and is referred to a specialist.
  2. Specialist evaluates the patient’s condition and recommends wrist arthroscopy as a treatment option.
  3. Patient undergoes pre-operative tests and preparation for the surgery.
  4. On the day of the surgery, patient is admitted to the hospital or surgical center.

After wrist arthroscopy:

  1. Patient is taken to the operating room and given anesthesia.
  2. Surgeon performs the wrist arthroscopy procedure, using small incisions and a camera to visualize and treat the wrist joint.
  3. After the procedure, patient is taken to the recovery room for monitoring.
  4. Patient may experience pain, swelling, and stiffness in the wrist following the surgery.
  5. Patient is given post-operative instructions for care and rehabilitation of the wrist.
  6. Patient follows up with the surgeon for post-operative appointments to monitor healing and recovery progress.

What to Ask Your Doctor

Some questions a patient should ask their doctor about wrist arthroscopy may include:

  1. What specific structures in my wrist will be visualized and potentially treated during the arthroscopy procedure?
  2. How much force will be applied to my wrist during the procedure, and how does this compare to the findings of the study on force patterns in wrist arthroscopy?
  3. What are the potential risks and complications associated with wrist arthroscopy, particularly in terms of the forces applied during the procedure?
  4. How experienced are you in performing wrist arthroscopy, and what measures do you take to ensure patient safety during the procedure?
  5. How will my recovery process be impacted by the forces applied during the arthroscopy procedure, and what can I expect in terms of post-operative pain and rehabilitation?
  6. Are there alternative treatment options to wrist arthroscopy that I should consider, and how do the risks and benefits compare?
  7. Can you provide me with more information on the success rates of wrist arthroscopy for my specific condition, and what factors may influence the outcome of the procedure?
  8. How will you monitor my progress after the arthroscopy procedure, and what signs should I watch for that may indicate complications related to the forces applied during the surgery?
