Hip Distraction

Background: Hip arthroscopy for femoroacetabular impingement (FAI) syndrome continues to gain popularity and indications for its use are expanding. Though low complication rates have previously been reported, there are iatrogenic complications specific to the use of the perineal post, such as pudendal nerve injuries, and possible pressure skin necrosis that warrant concern in the healthy young patient. The risk of these complications are increased during simultaneous bilateral hip arthroscopy. Indications: We describe a new technique, which will prevent such problems by using a postless pink pad technique in order to achieve adequate hip distraction. Technique Description: Arthroscopic investigation begins with proper, safe patient positioning in order to gain access to the hip joint with sufficient joint distraction. In the postless technique, a dense foam pad is utilized in lieu of a perineal post. The static friction between the pad, bed, and the patient counters the manual gross traction necessary to distract the hip joint while preventing the patient from sliding down or off of the operating table. The postless technique avoids pressure to the perineum and also allows for greater range of motion during dynamic intraoperative examination and femoroplasty. After hip distraction, standard portal placement allows for access to the central compartment in order to assess intraarticular pathology. Once identified on diagnostic arthroscopy, appropriate techniques are utilized to correct acetabular-sided pincer lesions, labral tears, and femoral-sided cam deformities. Results: When discussing this technique with patients, it is important to highlight that it diminishes the possibility of iatrogenic pressure injury to the pudendal nerve and skin of the perineum. The risk of these injuries typically occurs when the pudenal nerve is compressed against the post during traction and abduction. As such, postless technique prevents any compression and pressure to these regions. Discussion/Conclusion: Hip arthroscopy is a minimally invasive, low morbidity technique for treating a variety of chondral, ligamentous, and bony conditions of the hip. However, studies suggest that pudenal nerve injury is seen in up to 4.3% of patients following hip arthroscopy. Given avoidance of iatrogenic post complications, we describe a postless technique for achieving hip distraction during hip arthroscopy.

Abstract This study evaluated the effects of venting and capsulotomy on the ratio of normalized distraction distance to traction force, correlating this trend with patient demographic factors. A ratio was chosen to capture the total effect of each intervention on the hip joint. During primary hip arthroscopy, continuous traction force was recorded, and fluoroscopic images were acquired to measure joint distraction before and after the application of traction, venting and interportal capsulotomy. Distraction–traction force ratios were compared using a one-sided paired t-test. A linear regression model was used to determine the relationship between age, sex and body mass index and pre- and post-intervention distraction–traction force ratios. Seventy-two adult patients and 73 hips were included. There was an increase in hip distraction with a decrease in traction force post-venting and capsulotomy (both P’s <0.001). Mean normalized distraction distance increased 1.5% of femoral head size after venting and an additional 2.2% of femoral head size after capsulotomy. Mean traction force decreased 2.2% (14.7 N) after venting and 2.3% (15.3 N) after capsulotomy. Female sex significantly correlated with larger differences in both pre- and post-venting capsulotomy ratios. Venting and capsulotomy both independently improve the ratio of normalized distraction distance to traction force when performed in vivo. However, the effect sizes of each intervention are small and of questionable clinical significance. Specifically, when adequate distraction for safe surgical hip access cannot be obtained despite application of significant traction force, venting and capsulotomy after the application of traction may not afford substantial improvement.

Background: Hip arthroscopy has traditionally been performed with a perineal post, resulting in various groin-related complications, including pudendal nerve neurapraxias, vaginal tears, and scrotal necrosis. Purpose: To assess the safety of a technique for hip distraction without the use of a perineal post. Study Design: Case series; Level of evidence, 4. Methods: We prospectively analyzed a consecutive cohort of 1000 hips presenting to a dedicated hip preservation clinic; all patients had hip pain and were subsequently treated with hip arthroscopy. Demographic variables, hip pathology, and lateral center edge angle were recorded for each case. In the operating room, the patient’s feet were placed in traction boots in a specifically designed distraction setup, and the operative table was placed in varying degrees of Trendelenburg. With this technique, enough resistance is created by gravity and friction between the patient’s body and the bed to allow for successful hip distraction without the need for a perineal post. In a subset of 309 hips (n = 281 patients), the degrees of Trendelenburg as well as the distraction force were analyzed. Results: The mean ± SD Trendelenburg angle used among the subset of 309 hips was 11° ± 2°. The mean initial distraction force necessary was 90 ± 28 lb, which decreased to 65 ± 24 lb by 30 minutes after traction initiation ( P < .0001). The most important variables in determining initial force for this cohort of patients were, in order of magnitude, sex ( P < .0001), weight ( P < .0001), and lateral center edge angle ( P < .01). No groin-related complications occurred among the entire cohort of patients, including soft tissue or nerve-related complications. The rate of deep venous thrombosis was 2 in 1000. Conclusion: The use of the Trendelenburg position and a specially designed distraction setup during hip arthroscopy allows for safe hip distraction without a perineal post, thereby eliminating groin-related soft tissue and nerve complications. Certain patient variables can be used to estimate the required distraction force and inclination angle with this method.
