Stainless-steel screws are commonly used for fragment fixation during periacetabular osteotomy (PAO) at our institutions. Titanium is reserved for patients with documented nickel allergies. Titanium screws possess a significantly lower Young’s modulus than stainless steel and, therefore, potentially less resistance to physiologic loading. Thus, we hypothesized that the use of titanium screws might be associated with changes in acetabular correction prior to healing. The aim of this study was to compare the maintenance of acetabular correction following PAO using stainless-steel or titanium screws. A documented nickel allergy was confirmed with an allergy specialist. Patients’ age at surgery, gender and BMI were collected. The lateral center–edge angle of Wiberg (LCEA), medial center–edge angle (MCEA), anterior wall index (AWI), posterior wall index (PWI) and Tönnis angle were measured. The delta value for radiographic parameters was calculated as the difference between values immediately post-operation and at 6 months post-operation. Only age at surgery (P < 0.001) and the pre-operative LCEA (P = 0.013) were significantly different between groups (Tables I and II). The remaining pre- and post-operative radiological measurements were similar (Table II). Comparison of delta values at 6 months follow-up indicated no significant differences between screw types (Table III). No patients in the titanium group had a trans-iliac retrograde screw included in their construct (P = 0.003). All patients healed from their osteotomies. The use of titanium screws in patients with an allergy to nickel was not associated with differences in acetabular correction or the rate of osseous union rates despite its lower inherent mechanical properties.

Patient education is important as it gives patients a better understanding of the risks and benefits of medical and surgical interventions. Developing communication technologies have completely changed and enhanced patient access to medical information. The aim of this study was to evaluate available patient education materials (PEMs) regarding hip surgery on the websites of major hip societies and centers. The PEM from 11 selected leading hip centers and societies were evaluated with the following assessment tools: Flesch–Kincaid (FK) readability test, Flesch Reading Ease formula, Literature-Intelligence-Data-Analysis (LIDA) instrument and Discernibility Interpretability Sources Comprehensive Evidence Relevance Noticeable (DISCERN) tool. Videos were assessed using Patient Educational Video Assessment Tool (PEVAT). A total of 69 educational items, including 52 text articles (75.4%) and 17 videos (24.6%) were retrieved and evaluated. The median Interquartile Range (IQR) FK level of 52 text articles was 10.8 (2.2). The median (IQR) LIDA score of text articles by center was 45. According to the LIDA score, 60% of all website articles demonstrated high accessibility (LIDA score > 44). The median DISCERN score of text articles by center was 69. Overall, 52 (100%) of the text articles were deemed to be at ‘good’ quality rating or higher, and 23.2% (16 out of 69) of the articles had excellent quality. The mean PEVAT score for the 17 videos was 25 ± 1.9. Analysis of text and video articles from the 11 leading orthopedic surgery centers and societies demonstrated that by selecting a reliable source of information from main scientific societies and major centers in hip surgery, patients can find more accurate information regarding their hip conditions.

Femoral deformities are common in developmental dysplasia of the hip (DDH), but decisions about how to treat them are not standardized. Of interest are deformities that may be akin to cam femoroacetabular impingement (FAI). We used three-dimensional and two-dimensional measures to clarify the similarities and differences in proximal femur shape variation among female patients with DDH (n = 68) or cam FAI (n = 60). Three-dimensional measures included femoral head asphericity, as well as shape variation using statistical shape modeling and principal component analysis (PCA). Two-dimensional measures included the α-angle, head–neck offset (HNO) and the neck–shaft angle (NSA). Significant shape variations were captured in the first five PCA modes, with the greatest shared variation between groups being the length from the lesser trochanter to the femoral head and greater trochanter height. Variations unique to DDH were irregularities at different areas of the femoral head, but not at the lateral femoral head–neck junction where variation was strong in FAI. The FAI group also had unique variations in greater trochanter shape. DDH femoral heads were less spherical, as indicated by larger sphere-fitting errors (P < 0.001). Radiographically, the DDH group had significantly smaller α-angles (P < 0.001), larger head–neck offsets (P = 0.02) and larger NSAs (P < 0.001). Both the articular and extra-articular regions of the proximal femur have distinct shape features in DDH and cam FAI that can uniquely affect the biomechanics of each disorder. Accordingly, approaches to addressing each disorder should be unique.

Decision-making regarding surgical treatment of patients showing radiographic evidence of femoroacetabular impingement syndrome (FAIS) in the setting of borderline hip dysplasia (BHD) remains a challenge as there is no consensus on treatment in current literature. When medical evidence is unclear, understanding patient preferences becomes particularly important in deciding the optimal treatment for each patient. The purpose of this study was to measure the patient-determined importance of factors surrounding surgical treatment of FAIS in BHD. Patients aged 18–65 with hip pain and BHD (defined as lateral center edge angle 18–25 or Tonnis angle 10–15) morphology were given a discrete-choice experiment (DCE) focusing on attributes that differ between treatment options: Length of Hospital Stay, Major Complication Rate, Chance of Needing Reoperation within 2 Years and Time to Return to Regular Exercise. This DCE was used to calculate treatment preferences, relative attribute importance and preference weights. A total of 101 patients fully completed the DCE. The most important attribute (average importance weight, 95% CI) was Chance of Reoperation (60.16, 56.99–63.34), while the least important was Hospital Stay (6.57, 5.73–7.41). Only 6 Months to Resume Regular Exercise and 2% Chance of Reoperation (P < 0.05) significantly impacted treatment choice. When presented with fixed choice parameters, 50.5% of subjects preferred PAO and arthroscopy while 49.5% opted for arthroscopy alone. When no clear surgical treatment is indicated, patient preferences have an amplified role in patient decision-making. Our results confirm variation in attribute importance within treatments as well as treatment choice, highlighting the importance in understanding patient preferences in decision-making for FAIS in BHD. More patient-specific generalizable outcomes of surgical treatment options are needed in the literature.

It is well known that increased posterior tilt of the pelvis is an effective strategy for avoiding impingement of the femur with the pelvis during movement. Daily repetitive collisions become mechanical loads, and the more frequently they occur, the more tissue damage and pain they cause. Therefore, reducing the rate of occurrence of impingement is important to avoid aggravation of symptoms. This study aimed to evaluate the effects of changes in posterior pelvic tilt on the risk of impingement between the femur and the anterior inferior iliac spine (AIIS)/subspine in various functional postures. Patients with femoroacetabular impingement syndrome (FAIS) who were candidates for hip arthroscopic osteochondroplasty between October 2013 and June 2020 were included. A three-dimensional reconstructed model was used to simulate the incidence of impingement at 12 hip positions required for activities of daily living. We predicted value of the spatial incidence of impingement assumed that hip motion should exceed 130/30 degrees without impingement. Impingement was measured at three pelvic positions: an anterior tilt of 10°, in the functional pelvic plane and a posterior tilt of 10°. Multivariate linear-mixed models were used to assess the effect of covariate-adjusted posterior pelvic tilt on the impingement incidence in the AIIS region. AIIS type, center-edge angle, acetabular version and femoral version were used as covariates. The impingement rates and locations of the three pelvic tilt postures were assessed. Seventy-eight patients (60 males and 18 females; average age, 46 ± 15.1 years) with FAIS were analyzed. A multivariate linear-mixed model revealed a coefficient of -0.8% (95% confidence interval -0.9 to -0.7%; P < 0.001) for posterior pelvic tilt. Thus, posterior pelvic tilt affects AIIS impingement incidence. After adjusting for anatomical effects, the posterior pelvic tilt should be addressed to avoid impingement.

This study aims to examine the trends and demographics of periacetabular osteotomy (PAO) in the United States from 2016 to 2020 using a large healthcare database analysis. The PearlDiver database was queried for patients who underwent a PAO procedure starting with current procedural terminology (CPT) codes 27299, S2115 and 27146. Subsequently, the population was filtered for patients being ages 12–50, having an inpatient charge-type and those having a length of stay of at least 1 day. Patients with total hip arthroplasty were filtered out, and the resulting population was filtered by ICD-10 diagnosis codes. The providers of each patient were also examined to ensure their history of treating hip dysplasia. Student t and multiple regression analysis tests were used for statistical comparisons and trends analysis (P < 0.05 reported as significant). A total of 535 consecutive patients were analyzed over the study period. There was a higher incidence of PAO in females compared with males (P < 0.001) and a higher incidence of PAO in patients aged 15–19 years compared with older age groups (P = 0.017). Within the first year after the index PAO, 171 of the 535 patients, almost one-third (32%), received a reoperation. Of the 171 reoperations, 115 were deep removal of implant, 55 were a hip arthroscopy and 1 patient had a bone excision for heterotopic ossification. Similar studies should be carried out using other large health databases to confirm the external validity of these trends and rates across the United States.
本研究旨在通过大型医疗保健数据库分析，研究 2016 年至 2020 年美国髋臼周围截骨术（PAO）的发展趋势和人口统计数据。研究人员从 PearlDiver 数据库中查询了接受 PAO 手术的患者，这些患者的当前手术术语（CPT）代码为 27299、S2115 和 27146。随后，筛选出年龄在 12-50 岁、住院费用类型和住院时间至少为 1 天的患者。过滤掉了全髋关节置换术患者，并根据 ICD-10 诊断代码过滤出了患者群体。此外，还对每位患者的医疗服务提供者进行了调查，以确保他们有治疗髋关节发育不良的历史。统计比较和趋势分析采用了学生 t 检验和多元回归分析检验（P < 0.05 为显著）。在研究期间，共对 535 名连续患者进行了分析。女性 PAO 发病率高于男性（P < 0.001），15-19 岁患者 PAO 发病率高于老年患者（P = 0.017）。在指数 PAO 后的第一年内，535 名患者中有 171 人（近三分之一（32%））接受了再次手术。在这 171 例再次手术中，115 例是深部移除植入物，55 例是髋关节镜手术，1 例患者因异位骨化进行了骨切除术。应利用其他大型健康数据库开展类似研究，以确认全美这些趋势和比率的外部有效性。

The association between preoperative pain catastrophizing and postoperative patient-reported outcome measures of patients with pre-arthritic hip disease was evaluated. All patients scheduled for joint-preserving surgeries of the hip (JPSH) at our institution were approached. Patient demographics (age, sex, body mass index (BMI)), pain intensity (Numeric Pain Scale (NPS)) and pain catastrophizing (Pain Catastrophizing Scale (PCS)) were collected preoperatively. Patient function (12-Item International Hip Outcome Tool (iHot-12)) and physical and mental health (Patient-Reported Outcomes Measurement Information System (PROMIS-10) mental/physical) were collected preoperatively, three-month and one-year postoperatively. The analysis consisted of multivariate linear regression models fitted for continuous scores of outcome measures at three-month and one-year. Correlation between preoperative PCS and iHot-12 was assessed using the Pearson correlation coefficient. A total of 274 patients completed the PCS and were included in the multivariate linear regression models. Most patients were females (66.8%), mean age was 33 (SD 9), mean BMI was 26.5 (SD 5.8) and most were diagnosed with femoro-acetabular impingement (46.0%) and underwent arthroscopy (77.0%). There were statistically significant correlations between PCS and iHot-12 (preoperatively −0.615, P < 0.001; three-month −0.242, P = 0.002). Statistically significant associations were found for function (three-month PCS P = 0.046, age P = 0.014, NPS P = 0.043; one-year BMI P = 0.005, NPS P = 0.014), physical health (three-month BMI, P = 0.002, NPS P = 0.008; one-year BMI P = 0.002, NPS P = 0.013) and mental health (three-month BMI P = 0.047; one-year BMI P = 0.030). There is an association between function and preoperative pain catastrophizing in patients with pre-arthritic hip disease undergoing JPSH. When considering confounding variables, preoperative pain catastrophizing is associated with short-term recovery.
本研究评估了关节炎前髋关节疾病患者术前疼痛灾难化与术后患者报告结果之间的关联。研究对象是本院所有计划接受髋关节保留手术（JPSH）的患者。术前收集了患者的人口统计学资料（年龄、性别、体重指数（BMI））、疼痛强度（数值疼痛量表（NPS））和疼痛灾难化（疼痛灾难化量表（PCS））。术前、术后三个月和一年的患者功能（12项国际髋关节结果工具（iHot-12））和身心健康（患者报告结果测量信息系统（PROMIS-10）心理/生理）数据均已收集。分析包括针对术后三个月和一年的结果测量连续得分的多变量线性回归模型。使用皮尔逊相关系数评估了术前 PCS 与 iHot-12 之间的相关性。共有 274 名患者完成了 PCS，并被纳入多元线性回归模型。大多数患者为女性（66.8%），平均年龄为 33 岁（SD 9），平均体重指数为 26.5（SD 5.8），大多数患者被诊断为股骨髋臼撞击症（46.0%），并接受了关节镜手术（77.0%）。PCS与iHot-12之间存在统计学意义上的显著相关性（术前-0.615，P < 0.001；三个月-0.242，P = 0.002）。在功能（三个月 PCS P = 0.046，年龄 P = 0.014，NPS P = 0.043；一年 BMI P = 0.005，NPS P = 0.014）、身体健康（三个月 BMI，P = 0.002，NPS P = 0.008；一年 BMI P = 0.002，NPS P = 0.013）和心理健康（三个月 BMI P = 0.047；一年 BMI P = 0.030）方面发现了具有统计学意义的关联。接受髋关节置换术前关节炎患者的功能与术前疼痛灾难化之间存在关联。考虑到混杂变量，术前疼痛灾难化与短期康复有关。

The coronavirus disease 2019 pandemic has significantly affected people worldwide. Herein, we present a case of massive heterotopic ossification (HO) of the right hip following severe SARS-CoV-2 infection. The exact origin of HO development is still unknown, but a critical illness, chronic immobilization and hypoxia are important risk factors. Considering the location and size of the HOs in this case, modified Ludloff’s medial approach of the hip was used. This approach allows for good exposure and access to the medial and inferior part of the hip joint and the successful extirpation of the pathologic tissue.
冠状病毒疾病 2019 年的大流行给全世界人民带来了重大影响。在此，我们介绍一例严重感染 SARS-CoV-2 后右侧髋关节大量异位骨化（HO）的病例。HO发生的确切原因尚不清楚，但危重疾病、长期固定和缺氧是重要的风险因素。考虑到该病例中 HO 的位置和大小，采用了改良的 Ludloff 髋关节内侧入路。这种方法可以很好地暴露和进入髋关节的内侧和下部，并成功地切除病变组织。

To define Minimally Clinically Important Difference (MCID) and Patient Acceptable Symptomatic State (PASS) threshold scores after open gluteus medius and/or minimus repair. Primary open gluteus medius and/or minimus repair patients from November 2013 to March 2020 were identified. Patient reported outcomes (PROs) were assessed preoperatively, 1- and 2-year follow-up, including the Hip Outcome Score Activities of Daily Living (HOS-ADL), modified Harris Hip Score (mHHS), International Hip Outcome Tool-12 (iHOT-12) and Visual Analog Scale (VAS) Pain. Thresholds for achieving a MCID and PASS postoperatively were calculated using the distribution method and receiver operator curve analysis; 25 patients (24 females, 1 male, age: 69 ± 6.8 years, body mass index: 26.9 ± 5.0 kg/m2) were included in final analyses. MCID threshold scores for HOS-ADL, mHHS, iHOT-12 and VAS Pain were calculated as 11.1, 6.2, 15.3 and 14.0, respectively. PASS threshold scores for each of the PROs were as follows: HOS-ADL (71.9), mHHS (60.0), iHOT-12 (49.2) and VAS Pain (36.8). MCID thresholds for HOS-ADL, mHHS, iHOT-12 and VAS Pain were achieved by 58.3%, 83.3%, 66.7% and 57.1% of patients, respectively. PASS thresholds for HOS-ADL, mHHS, iHOT-12 and VAS Pain were achieved by 52.4%, 44.8%, 65% and 59.1% of patients, respectively. Open gluteus medius and/or minimus repair results in a high rate of achievement of clinically significant outcomes at a minimum of 2 years postoperatively. MCID threshold values for HOS-ADL, mHHS, iHOT-12 and VAS Pain were 11.1, 6.2, 15.3 and 14.0, respectively. PASS threshold values for HOS-ADL, mHHS, iHOT-12 and VAS Pain were 71.9, 60.0, 49.2 and 36.8, respectively. The majority of patients achieved clinically significant outcomes with 81.3% and 77.3% achieving MCID and PASS for at least one PRO, respectively.

The purpose of this systematic review is to (i) compare post-operative activity levels after periacetabular osteotomy (PAO) versus PAO + HA (concomitant PAO and hip arthroscopy) using patient-reported outcomes that specifically assess activity and sports participation [Hip Disability and Osteoarthritis Outcome Score—Sport and Recreation subscale (HOOS-SR), University of California Los Angeles (UCLA) activity score, Hip Outcome Score—Sport-Specific Subscale (HOS-SSS)] and (ii) compare post-operative return to sport (RTS) data between PAO and PAO + HA groups. A systematic review of literature was conducted on 1 June 2023, utilizing PubMed, Cochrane and Embase (OVID). Articles were screened for inclusion using specific inclusion and exclusion criteria. Twenty-six out of 1610 articles met all inclusion criteria, without meeting any exclusion criteria. In the 12 studies containing only subjects who underwent PAO alone, 11 demonstrated an average score improvement in UCLA, HOOS-SR or HOS-SSS post-operatively (P < 0.05). In the three studies containing subjects who underwent PAO with concomitant HA, significant improvements were seen in the HOS-SS and UCLA scores (P < 0.05). In the five studies that directly compared UCLA, HOS-SSS and HOOS-SSS scores between PAO groups and PAO + HA groups, all demonstrated statistically significant improvement post-operatively (P < 0.05). The rate of RTS ranged from 63% to 90.8% among PAO studies and was found to be 81% in the single PAO + HA study that assessed RTS. When performed in patients with intra-articular pathology, concomitant PAO + HA may provide similar sport-related outcomes to PAO alone in patients without intra-articular pathology.
本系统性综述的目的是：(i) 使用专门评估活动和运动参与情况的患者报告结果[髋关节残疾和骨关节炎结果评分--运动和娱乐子量表（HOOS-SR）、加利福尼亚大学洛杉矶分校（UCLA）活动评分、髋关节结果评分--运动场所特定子量表（HOS-SSS）]，比较髋臼周围截骨术（PAO）与 PAO + HA（同时进行 PAO 和髋关节镜检查）术后的活动水平；(ii) 比较髋臼周围截骨术与髋关节镜检查术后的运动恢复（RTS）数据、加利福尼亚大学洛杉矶分校（UCLA）活动评分、髋关节结果评分-运动特定分量表（HOS-SSS）]；(ii) 比较 PAO 组和 PAO + HA 组的术后恢复运动（RTS）数据。2023 年 6 月 1 日，利用 PubMed、Cochrane 和 Embase (OVID) 对文献进行了系统性审查。采用特定的纳入和排除标准对文章进行筛选。在 1610 篇文章中，有 26 篇符合所有纳入标准，且不符合任何排除标准。在仅包含接受单纯 PAO 的受试者的 12 项研究中，11 项研究显示术后 UCLA、HOOS-SR 或 HOS-SSS 平均得分有所提高（P < 0.05）。在包含同时接受 PAO 和 HA 的受试者的三项研究中，HOS-SS 和 UCLA 评分均有显著改善（P< 0.05）。在直接比较 PAO 组和 PAO + HA 组之间 UCLA、HOS-SSS 和 HOOS-SSS 评分的五项研究中，所有研究均显示术后评分有明显的统计学改善（P &;lt;0.05）。在 PAO 研究中，RTS 的发生率从 63% 到 90.8% 不等，在一项评估 RTS 的 PAO + HA 研究中，RTS 的发生率为 81%。如果在有关节内病变的患者中实施 PAO + HA，那么在没有关节内病变的患者中，同时实施 PAO + HA 可提供与单独 PAO 相似的运动相关结果。
