Hip arthroscopy for challenging deformities: posterior cam decompression.

ABSTRACT: Since the classic description of cam femoroacetabular impingement occurring in the anterolateral quadrant of the proximal femur, there has been growing evidence of cam impingement extending outside of this region. Although anteromedial cam decompression may be performed, posterior cam decompression is at higher theoretic risk of vascular embarrassment with osteonecrosis and/or tensile failure with fracture, leading some investigators to believe that these major deformities require open surgical correction. We present a less invasive method of arthroscopic posterior cam decompression using the modified midanterior portal while avoiding the posterolateral vasculature of the proximal femur.

Hip arthroscopy for challenging deformities: global pincer femoroacetabular impingement.

Project description:Pincer femoroacetabular impingement occurs in focal or global forms, the latter having more generalized and typically more extreme acetabular overcoverage. Severe global deformities are often treated with open surgical dislocation of the hip. Arthroscopic technical challenges relate to difficulties with hip distraction; central-compartment access; and instrument navigation, acetabuloplasty, and chondrolabral surgery of the posterior acetabulum. Techniques addressing these challenges are introduced permitting dual-portal hip arthroscopy with central-compartment access, subtotal acetabuloplasty, and circumferential chondrolabral surgery. The modified midanterior portal in combination with a zone-specific sequence of acetabular rim reduction monitored with fluoroscopic templating enables precision subtotal acetabuloplasty. Guidelines for acetabular rim reduction include the following suggested radiographic endpoints: postoperative center-edge angle of 35°, a neutral posterior wall sign, and an anterior margin ratio of 0.5. Arthroscopic zone-specific chondrophobic rim preparation and circumferential labral reparative and reconstructive techniques and tools permit the arthroscopic treatment of these challenging deformities.

Intraoperative Guidance for the Surgical Correction of Cam Deformities Using Hip Arthroscopy Based on Alpha Angle Measurement.

Project description:Residual femoroacetabular impingement syndrome due to incomplete resection of a cam deformity is the leading cause of failed hip arthroscopy. The reliability of the alpha angle has been shown for quantifying cam deformities in femoroacetabular impingement syndrome. An intraoperative navigation tool that provides the ability to compare alpha angle measurements side by side on pre- and post-resection fluoroscopic images has recently been introduced. This tool uses fluoroscopic images obtained in 6 different hip positions. The reliability of these standardized hip positions has been shown by correlation with computed tomography in localization and visualization of cam deformities. The purpose of this Technical Note is to give technical tips about the application of this tool.

Posterior Femoral Cam Decompression Through an Arthroscopic Anterior Approach With Pre-Bent Hip Burrs.

Project description:Hip arthroscopy has been increasingly used to treat labral tears and cam and pincer lesions found in femoroacetabular impingement. Although the classic impingement with cam deformity at the proximal femoral anterolateral quadrant is most common, there has been evidence of cam impingement extension to the anteromedial and posterior quadrants of the proximal femur. Posterior cam decompression carries a theoretical risk of vascular insult and subsequent osteonecrosis, which have led investigators to approach these posterior lesions through an open surgical correction. Recent improvements have led to the development of pre-bent burs that allow for bonier resection flexibility. Here, we report on an arthroscopic posterior cam decompression using the traditional anterior portals and curved hip burs via a figure-of-four positioning technique.

Decompression of Posterior Ankle Impingement With Concomitant Anterior Ankle Pathology by Posterior Ankle Arthroscopy in the Supine Position.

Project description:Posterior ankle endoscopy is a safe and effective approach for treatment of posterior ankle impingement. This is usually performed with the patient in prone position. The purpose of this technical note is to describe an arthroscopic approach of decompression of posterior ankle impingement with the patient in supine position. This is indicated if there is posterior ankle impingement together with other ankle pathology requiring anterior ankle arthroscopy. This approach allows treatment of both anterior ankle and posterior ankle pathology with the patient in the supine position. Concomitant anterior ankle arthroscopy can be performed with the usual orientation without the need of change of patient's position.

Basic Hip Arthroscopy: Diagnostic Hip Arthroscopy.

Project description:Hip arthroscopy is increasing in popularity for the diagnosis and management of hip preservation. The basics of hip arthroscopy positioning, fluoroscopic assessment, and portal establishment are reviewed in the first 2 parts of this series. This article is the third installment in which we describe a systematic approach to performing a diagnostic hip arthroscopy. A mastery of diagnostic arthroscopy is necessary for surgeons treating hip disorders.

Closed intramedullary derotational osteotomy and hip arthroscopy for cam femoroacetabular impingement from femoral retroversion.

Project description:Femoral retroversion is an uncommon cause of cam femoroacetabular impingement that may require surgical treatment beyond arthroscopic or open femoroplasty. We present the case of a young adult with bilateral severe femoral retroversion in whom such treatment failed. We discuss the rationale, surgical technique, and outcome of this patient, who underwent bilateral closed intramedullary derotational proximal femoral osteotomies and interlocked nailing with adjunctive pre- and post-osteotomy hip arthroscopies. Clinical improvement with normal foot progression angles, radiographic union, and resolution of bilateral cam femoroacetabular impingement from femoral retroversion was achieved. This surgery permits rapid institution of weight-bearing ambulation and an early rehabilitative program. Femoral retroversion may be an underappreciated and insufficiently treated cause of cam femoroacetabular impingement that may be readily detected and successfully remedied with this less invasive procedure.

Remplissage of the Femoral Head-Neck Junction in Revision Hip Arthroscopy: A Technique to Correct Excessive Cam Resection.

Project description:Femoroacetabular impingement (FAI) is an increasingly recognized cause of hip pain. This pathology often involves abnormal femoral neck shape (cam-type FAI), acetabular over coverage (pincer-type FAI), or mixed pathology. Surgical treatment of this entity includes labral repair and femoral head-neck osteochondroplasty. A mindful arthroscopic technique is of paramount importance, because maintaining the integrity of the labrum and a corresponding neck volume has been reported to be vital in maintaining the hip suction seal. Arthroscopic resection of the cam deformity must be performed with care to ensure appropriate femoral offset and maintenance of appropriate femoroacetabular contact. Although the most common cause of failure after hip arthroscopy is incomplete resection of a cam lesion, a previously unrecognized complication is excessive cam resection that can also lead to excessive femoral offset and loss of the suction seal. The purpose of this technical note is to describe the technique for arthroscopic recognition of excessive cam decompression leading to loss of the suction seal and a surgical treatment approach using the "remplissage" technique.

Hip arthroscopy update.

Project description:The management of hip injuries in the athlete has evolved significantly in the past few years with the advancement of arthroscopic techniques. The application of minimally invasive surgical techniques has facilitated relatively rapid returns to sporting activity in recreational and elite athletes alike. Recent advancements in both hip arthroscopy and magnetic resonance imaging have elucidated several sources of intraarticular pathology that result in chronic and disabling hip symptoms. Many of these conditions were previously unrecognized and thus, left untreated. Current indications for hip arthroscopy include management of labral tears, osteoplasty for femoroacetabular impingement, thermal capsulorrhaphy and capsular plication for subtle rotational instability and capsular laxity, lateral impact injury and chondral lesions, osteochondritis dissecans, ligamentum teres injuries, internal and external snapping hip, removal of loose bodies, synovial biopsy, subtotal synovectomy, synovial chondromatosis, infection, and certain cases of mild to moderate osteoarthritis with associated mechanical symptoms. In addition, patients with long-standing, unresolved hip joint pain and positive physical findings may benefit from arthroscopic evaluation. Patients with reproducible symptoms and physical findings that reveal limited functioning, and who have failed an adequate trial of conservative treatment will have the greatest likelihood of success after surgical intervention. Strict attention to thorough diagnostic examination, detailed imaging, and adherence to safe and reproducible surgical techniques, as described in this review, are essential for the success of this procedure.

Ultrasound-assisted hip arthroscopy.

Project description:We describe the use of intraoperative ultrasound for the safe development of arthroscopic portals during hip arthroscopy without the requirement for fluoroscopy. We find this technique consistently accurate, allowing the safe introduction of arthroscopic instruments into the hip with a very low rate of iatrogenic injury. We have further developed the technique for application to both central- and peripheral-compartment procedures. We now have a total experience of more than 700 procedures to date. With the described technique of ultrasound guidance for portal placement, fluoroscopy is required in fewer than 2% of hip arthroscopy procedures at our institution.

Simultaneous Bilateral Hip Arthroscopy.

Project description:Many patients are afflicted with painful conditions affecting both hips, most commonly femoroacetabular impingement. Some patients prefer the advantage of undergoing a single surgical procedure and anesthetic followed by a single postoperative rehabilitation program. We present a Technical Note on single-stage bilateral hip arthroscopy. This Technical Note reports on key steps enabling safe and efficient performance of bilateral arthroscopic acetabuloplasty, labral refixation, femoroplasty, and dynamic testing while limiting traction times and facilitating rapid transition to the second hip arthroscopic surgery. Enabling factors include supine positioning with bilateral mobile leg spars, rapid surgical and hip traction times, and postoperative rehabilitation with immediate weight bearing as tolerated. A rationale for deciding which hip should undergo arthroscopy first is also offered. Concurrent bilateral hip arthroscopy is a viable option for select patients and experienced surgical teams, enabling potentially expedited recovery and return to work or sport with inherent cost savings.
