Purpose. Radiological diagnosis of acetabular retroversion (AR) is based on the presence of the crossover sign (COS), the posterior wall sign (PWS), and the prominence of the ischial spine sign (PRISS). The primary purpose of the study is to analyze the clinical significance of the PRISS in a sample of dysplastic hips requiring periacetabular osteotomy (PAO) and evaluate retroversion in symptomatic hip dysplasia. Methods. In a previous paper, we reported the classic coxometric measurements of 178 patients with symptomatic hip dysplasia undergoing PAO where retroversion was noted in 42% of the cases and was not found to be a major factor in the appearance of symptoms. In the current study, we have added the retroversion signs PRISS and PWS to our analysis. Among the retroverted dysplastic hips, we studied the association of the PRISS with the hips requiring PAO. We also defined the ischial spine index (ISI) and studied its relationship to the coxometric measurements and AR. Results. In hips with AR, the operated hips were significantly associated with the PRISS compared to the nonoperated ones (χ2 = 4.847). Additionally, the ISI was able to classify acetabular version (anteverted, neutral, and retroverted acetabula). A direct correlation between the ISI and the retroversion index (RI) was found, and the highest degree of retroversion was found when the 3 signs of acetabular retroversion were concomitantly present (RI = 33.6%). Conclusion. The PRISS, a radiographic sign reflecting AR, was found to be significantly associated with dysplastic hips requiring PAO where AR was previously not considered a factor in the manifestation of symptoms and subsequent requirement for surgery. Moreover, the PRISS can also serve as an adequate radiographic sign for estimating acetabular version on pelvic radiographs.

The Relationship

Purpose: The aim of this study was to evaluate the relationship between acetabular 3-dimensional (3D) alignment reorientation and clinical range of motion (ROM) after periacetabular osteotomy (PAO). Methods: 50 patients (58 hips) with hip dysplasia participated in the study and underwent curved PAO. The pre- and postoperative 3D centre-edge (CE) angles and femoral anteversion were measured and compared with clinical outcomes, including postoperative ROM. Results: The correlation between pre- and postoperative acetabular coverage and postoperative ROM was evaluated. Postoperative abduction and internal rotation ROM were significantly associated with postoperative lateral CE angles (abduction; p < 0.001, internal rotation; p = 0.028); flexion and internal rotation ROM was significantly associated with postoperative anterior CE angles (flexion; p < 0.001, internal rotation; p = 0.028). Femoral anteversion was negatively correlated with postoperative abduction ( p = 0.017) and external rotation ( p = 0.047) ROM. Conclusion: Postoperative anterior acetabular coverage may affect internal rotation ROM more than the lateral coverage. Therefore, the direction of acetabular reorientation should be carefully determined according to 3D alignment during PAO.

Background: The technique of hip arthroscopic surgery is advancing and becoming more commonly performed. However, most current reported results are limited to short-term follow-up, and therefore, the durability of the procedure is largely unknown. Purpose: To perform a multicenter analysis of mid-term clinical outcomes of arthroscopic hip labral repair and determine the risk factors for patient outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Prospectively collected data of primary hip arthroscopic labral repair performed at 4 high-volume centers between 2008 and 2011 were reviewed retrospectively. Patients were assessed preoperatively and postoperatively with the visual analog scale (VAS), modified Harris Hip Score (mHHS), and Hip Outcome Score–Sports-Specific Subscale (HOS-SSS) at a minimum of 5 years’ follow-up. Factors including age, body mass index (BMI), Tönnis grade, and cartilage grade were analyzed in relation to outcome scores, and revision rates were determined. Failure was defined as subsequent ipsilateral hip surgery, including revision arthroscopic surgery and open hip surgery. Results: A total of 303 patients (101 male, 202 female) with a mean age of 32.0 years (range, 10.7-58.9 years) were followed for a mean of 5.7 years (range, 5.0-7.9 years). Patients achieved mean improvements in VAS of 3.5 points, mHHS of 20.1 points, and HOS-SSS of 29.3 points. Thirty-seven patients (12.2%) underwent revision arthroscopic surgery, and 12 (4.0%) underwent periacetabular osteotomy, resurfacing, or total hip arthroplasty during the study period. Patients with a BMI >30 kg/m2 had a mean mHHS score 9.5 points lower and a mean HOS-SSS score 15.9 points lower than those with a BMI ≤30 kg/m2 ( P < .01). Patients aged >35 years at surgery had a mean mHHS score 4.5 points lower and a HOS-SSS score 6.7 points lower than those aged ≤35 years ( P = .03). Patients with Tönnis grade 2 radiographs demonstrated a 12.5-point worse mHHS score ( P = .02) and a 23.0-point worse HOS-SSS score ( P < .01) when compared with patients with Tönnis grade 0. Conclusion: Patients demonstrated significant improvements in VAS, mHHS, and HOS-SSS scores after arthroscopic labral repair. However, those with Tönnis grade 2 changes preoperatively, BMI >30 kg/m2, and age >35 years at the time of surgery demonstrated significantly decreased mHHS and HOS-SSS scores at final follow-up.

Abstract A variety of options exist for management of patients with developmental dysplasia of the hip (DDH). Most studies to date have focused on clinical outcomes; however, there are currently no data on comparative cost of these techniques. The purpose of this study was to evaluate in-hospital costs between patients managed with periacetabular osteotomy, hip arthroscopy or a combination for DDH. One hundred and nine patients were included: 35 PAO + HA, 32 PAO and 42 HA. There were no significant differences in the demographic parameters. Operative times were significantly different between groups with a mean of 52 min for PAO, 100 min for HA and 155 min for PAO + HA, (P &lt; 0.001). Total direct medical costs were calculated and adjusted to nationally representative unit costs in 2017 inflation-adjusted dollars. Total in-hospital costs were significantly different between each of the three treatment groups. PAO + HA was the most expensive with a median of $21 852, followed by PAO with a median of $15 124, followed by HA with a median of $11 582 (P &lt; 0.001). There was a significant difference between outpatient median costs of $11 385 compared with $24 320 for inpatients (P &lt; 0.001). Procedures with greater complexity were more expensive. However, a change from outpatient to inpatient status with HA moved that group from the least expensive to similar to PAO and PAO + HA. These data provide an important complement to clinical outcomes reports as surgeons and policymakers aim to provide optimal value.

The Relationship

Background: Hip dysplasia is a complex, three dimensional diagnosis. Little is known about version (acetabular, femoral and the relationship between the two) in dysplastic patients. We sought to 1) compare femoral and acetabular version between hips that underwent a primary periacetabular osteotomy (PAO) versus nondysplastic hips (CEA >25degrees); 2) estimate the correlation between femoral and acetabular version in dysplastic hips; 3) estimate the correlation of femoral and acetabular version with preoperative range of motion in dysplastic hips; 4) estimate the association of femoral and acetabular version with patient-reported outcome measures 11-23 months postoperatively in patients that underwent PAO. We hypothesized an association between acetabular and femoral version, and an association between version and patient reported outcomes. Methods: We retrospectively reviewed our institution’s hip registry to identify all PAO patients from March 2010 and June 2016. We included patients who had pre-operative computed tomography (CT) imaging and a minimum of 1 year follow-up. We created a comparison group of non-dysplastic patients (CEA > 25degrees). We calculated the association between acetabular version, femoral version and hip range of motion (ROM), as well as between femoral version, acetabular version, age, sex, and preoperative and 1 year postoperative modified Harris Hip Score (mHHS), Hip Outcome Score (HOS), and International Hip Outcome Tool 33 (iHOT33) score. Results: 75 PAO patients met inclusion criteria (93% female, mean age 24) and 1332 non-dysplastic patients (45% female, mean age 25). Pre-operative CT measurements (95% CI) demonstrated mean CEA for our PAO patients was 24, and for the non-dysplastic group 37. We found a very weak correlation between acetabular version and femoral version. Dysplastic patients had significantly greater acetabular and femoral version than nondysplastic patients (8 vs 1 at 1 o’clock; 15 vs 10 at 2 o’clock; 21 vs 16 at 3 o’clock, FV 21 vs 14, all p<0.001). We found only a weak correlation of hip ROM to acetabular version, but there was a moderate correlation of hip ROM and femoral version. We found no evidence of an association between mHHS, HOS-activities of daily living (ADL), HOS-sport specific (SS), or iHOT-33 scores and pre-operative femoral version, acetabular version, age, or sex. Conclusions/Significance: Our current investigation confirmed a statistically higher acetabular and femoral version in dysplastic hips than nondysplastic hips. However, while acetabular version measurements correlated strongly, there was only a very weak correlation between acetabular version and femoral version. Pre-operative ROM was correlated only moderately with femoral version, but not correlated with acetabular version. Additionally there was no association with acetabular or femoral version and patient reported outcomes after PAO, suggesting that femoral version does not need to be addressed at the time of PAO surgery.
