Abstract

OBJECTIVE: To study the occurrence and radiograph features of the acetabular retroversion in hip dysplasia, and to evaluate the effects on the retroversion by the traditional maneuvers in the periacetabular osteotomy. METHODS: Bernese periacetabular osteotomy was performed to 45 continuous dysplastic hips (43 patients) from December 2001 to November 2003. There were 37 female (39 hips) and 6 male (6 hips), average age was 28.9 (range, 15-45). The diagnosis of acetabular retroversion was based on the "cross-over" and "posterior wall" signs on the standard radiographs of the patients pre- or postoperatively. RESULTS: Among total 45 hips, the "cross-over" sign was positive in 8 hips, whereas including the "posterior wall" sign positive in 5 hips. The occurrence of retroversion was 17.8%. And the cross-over points were located within the superior 1/3 of the acetabulums in all cases. After the osteotomy, all the cross-over points moved to the inferior 1/3 of the acetabulums, and the "posterior wall" sign was seen in all 8 cases. CONCLUSIONS: Approximately one sixth of the patients with acetabular dysplasia have retroversion in which the superior 1/3 of the acetabulum faces posterolaterally. The retroversion can be identified with the standard AP pelvic radiographs. With the traditional maneuvers in periacetabular osteotomy, the retroversion will be aggravated in these patients.

Classification and localization of acetabular labral tears.

OBJECTIVE: The purpose of this study was to compare the findings on hip MR arthrography (MRA) with the published MRA and arthroscopic classifications of hip labral tears and to evaluate a clock-face method for localizing hip labral tears. DESIGN/PATIENTS: We retrospectively reviewed 65 hip MRA studies with correlative hip arthroscopies. Each labrum was evaluated on MRA using the classification system of Czerny and an MRA modification of the Lage arthroscopic classification. In addition, each tear was localized on MRA by using a clock-face description where 6 o'clock was the transverse ligament and 3 o'clock was anterior. These MRA findings were then correlated with the arthroscopic findings using the clock-face method of localization and the Lage arthroscopic classification of labral tears. RESULTS: At MRA, there were 42 Czerny grade 2 and 23 grade 3 labral tears and 22 MRA Lage type 1, 11 type 2, 22 type 3 and 10 type 4 tears. At arthroscopy, there were 10 Lage type 1 flap tears, 20 Lage type 2 fibrillated tears, 18 Lage type 3 longitudinal peripheral tears and 17 Lage type 4 unstable tears. The Czerny MRA classification and the modified MRA Lage classification had borderline correlation with the arthroscopic Lage classification. Localization of the tears using a clock-face description was within 1 o'clock of the arthroscopic localization of the tears in 85% of the patients. CONCLUSIONS: The Lage classification, which is the only published arthroscopic classification system for hip labral tears, does not correlate well with the Czerny MRA or an MRA modification of the Lage classification. Using a clock-face description to localize tears provides a way to accurately localize a labral tear and define its extent.

Acetabular revisions using a cementless oblong cup: five to ten year results.

The purpose of this paper was to evaluate the results of acetabular revisions with the use of an oblong revision cup that is designed with its longitudinal diameter elongated relative to its transverse diameter. Between 1996 and 2001, 62 hips in 60 patients underwent an acetabular revision with the insertion of a LOR acetabular component. Seven hips were lost to follow-up or the patients died; the remaining 55 hips (53 patients) remained in follow-up for an average of 7.2 years (range: 5.0-10.1 years). One socket was revised for aseptic loosening, and another was operated on for a late polyethylene liner dissociation. The average Harris hip score (HHS) improved from 34 to 79. Results were rated as excellent in 16 hips, good in 28, fair in six and poor in three. Radiographic analysis demonstrated an improvement in the average vertical displacement of the hip centre: 49 hips had a well-fixed, bone-ingrown cup and four had a stable fibrous union. For large superolateral acetabular bone deficiencies, this implant facilitated a complex reconstruction without the need for bulk structural acetabular bone grafts, provided good clinical results and showed satisfactory stability at the midterm follow-up.

Corona mortis: an anatomical study with clinical implications in approaches to the pelvis and acetabulum.

The "corona mortis" is an anatomical variant, an anastomosis between the obturator and the external iliac or inferior epigastric arteries or veins. It is located behind the superior pubic ramus at a variable distance from the symphysis pubis (range 40-96 mm). The name "corona mortis" or crown of death testifies to the importance of this feature, as significant hemorrhage may occur if accidentally cut and it is difficult to achieve subsequent hemostasis. It constitutes a hazard for orthopedic surgeons especially in the anterior approach to the acetabulum. We carried out forty cadaver dissections (80 hemi-pelvises) through the ilioinguinal approach. A vascular anastomosis was found in 83% of specimens. Of these, 60% had a large diameter (>3 mm) channel along the posterior aspect of the superior pubic ramus. In clinical practice, however, 492 anterior approaches (to the best of our knowledge the largest series described) have been carried out over the last 15 years by the senior author (MB) and only five of these problematic vessels were discovered, and in only two cases was there troublesome bleeding. This study confirms a paradox: in anatomical dissections a large vessel was identified behind the superior pubic ramus, whereas in clinical practice this vessel does not seem to be as great a threat as initially perceived. Orthopedic surgeons planning an anterior approach to the acetabulum, such as the ilioinguinal or the intrapelvic approach (modified Stoppa), have to be cautious when dissecting near the superior pubic ramus. Despite the high prevalence of these large retropubic vessels in the dissecting room, surgeons should exercise caution but not alter their surgical approach for fear of excessive hemorrhage.
