What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new method for positioning patients during hip arthroscopy, a type of surgery on the hip joint. The goal is to determine if a special traction pad, called The Pink Pad Hip Kit, used with standard equipment, can reduce numbness around the groin area post-surgery. Participants will undergo surgery either with this new pad or the usual method without it. Eligible candidates are those scheduled for specific types of hip arthroscopy at Northwestern Memorial Hospital who can read and speak English. As an unphased trial, this study allows participants to contribute to innovative surgical techniques that may enhance recovery experiences for future patients.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this positioning technique is safe for hip surgery?

Research shows that using The Pink Pad Hip Kit during hip surgery can enhance safety. This device stabilizes patients and provides the necessary traction without a perineal post, which can sometimes cause temporary groin numbness. Studies indicate that positioning pads like The Pink Pad reduce pressure and increase patient comfort.

Reports suggest that complications, such as nerve problems, occur in up to 4.3% of cases with traditional methods. However, The Pink Pad lowers these risks by ensuring safer patient positioning. Overall, the device improves procedure safety by reducing the likelihood of these issues. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores a new positioning technique for hip arthroscopic surgery using The Pink Pad Hip Kit Patient Positioning System. Unlike standard procedures that don't use additional padding, this system introduces a specialized pad to enhance patient stability on the traction table. This could potentially increase comfort and reduce complications associated with the traditional method, which relies solely on a perineal post. By improving positioning, the Pink Pad may lead to better surgical outcomes and a more comfortable experience for patients undergoing hip surgery.

What evidence suggests that this positioning technique is effective for hip arthroscopic surgery?

Research has shown that the Pink Pad, a device used during hip surgery, can significantly reduce pressure on the area between the legs. In this trial, one group of participants will undergo hip arthroscopy using the Pink Pad. Studies have demonstrated that it lowers peak pressure by 43%, potentially reducing the risk of issues like numbness in that area. The pad creates grip between the patient, the pad, and the bed, allowing doctors to access the hip joint without excessive force. This method aims to make the surgery more comfortable and reduce postoperative issues. These findings suggest that using the Pink Pad during surgery could lead to better outcomes. ^{1 2 4 6 7}

Interventions

• Positioning for Hip Arthroscopic Surgery
• The Pink Pad Hip Kit

Trial Overview

The study tests the Pink Pad Hip Kit during hip arthroscopic surgery to see if it reduces postoperative numbness. The kit is used with a standard traction table and perineal post to lessen pressure on the groin area during surgery.

How Is the Trial Designed?

Published Research Related to This Trial

The supine position for hip arthroscopy was successfully used in 20 consecutive patients, demonstrating its effectiveness and reproducibility in the surgical procedure.

This technique is user-friendly for both surgeons and operating room staff, utilizing standard equipment with only minor modifications, which enhances its practicality in clinical settings.

Hip arthroscopy: the supine position. Byrd, JW.[2005]

Hip arthroscopy is an effective method for diagnosing and treating various hip conditions, utilizing a minimally invasive approach that enhances patient recovery.

Standardizing patient positioning and surgical setup during hip arthroscopy improves both patient safety and the efficiency of the surgical team, leading to better outcomes.

Basic Hip Arthroscopy: Supine Patient Positioning and Dynamic Fluoroscopic Evaluation. Mannava, S., Howse, EA., Stone, AV., et al.[2022]

Hip arthroscopy is a valuable tool for diagnosing and treating various hip joint conditions, but it requires specific training and knowledge of hip anatomy to minimize complications, particularly those related to joint traction.

The technique allows for a comprehensive inspection and treatment of the hip joint through multiple portals, with promising early results indicating its effectiveness for conditions like labral lesions and loose bodies.

In a study of 908 patients undergoing primary hip arthroscopy, the overall complication rate was found to be low at 7.3%, with minor complications occurring in 4.9% of cases and major complications in 2.4%.

The most common severe complications included iatrogenic cartilage damage and instrument breakage, while perineal hypoaesthesia and heterotopic ossifications were the most frequent minor complications, highlighting the importance of surgeon training and experience in minimizing risks.

In a study of 18 patients (9 with prior lower-extremity arthroplasty and 9 without), hip arthroscopy using traction resulted in significant improvements in hip function scores for both groups, indicating its efficacy.

The procedure was found to be safe, with only one postoperative complication in the group with prior arthroplasty, suggesting that traction during hip arthroscopy does not increase the risk of complications in patients with previous joint surgeries.
