The aim of this study was to analyze presence of the morphological characteristics and prevalence of FAI in asymptomatic adolescents and assess the relation of skeletal maturation with development of FAI morphology. Abdominopelvic computed tomography (CT) of 265 adolescents (9-19 years old) who were admitted to the emergency department between 2011 and 2016 were evaluated retrospectively. Radial reformatted CT images from the femoral neck were created using the multiplanar reconstruction (MPR) method. The femoral neck was divided into 12 segments and alpha angle (AA), femoral head-neck ratio (FHNR) and center-edge angle (CEA) were measured from each segment. Additionally, images were evaluated for the physiological status (open or closed) of the triradiate- cartilage and proximal femoral epiphyses. 204 hips from 102 patients (32 females, 70 males) were retrospectively reviewed. There were 27 (26.5%) patients with cam-type morphology and 18 (17.6%) patients with pincer-type morphologies. No statistically significant difference was detected between the prevalences of cam and pincer morphologies between the two genders. Cam deformity was most frequently seen in anterosuperior segment. All of the patients (100%) with pincer-type morphology and 88% of the patients with cam-type morphology had closed triradiate cartilage, 89% of the patients with cam morphology and 83% with pincer morphology had open proximal femoral physis. Our results showed that prevalence of cam and pincer-type morphology in asymptomatic adolescents is similar to asymptomatic adults. Our findings also indicate that cam- and pincer-type FAI morphologies likely develop during late adolescence after closure of triradiate cartilage and before closure of proximal femoral physis.

This retrospective observational study aimed to examine the correlation and correspondence between skeletal maturation indicators (SMI), cervical vertebral maturation indicators (CVMI), and radius-ulna-short bones (RUS) skeletal maturity scores in Korean adolescents, and to determine whether easily obtainable SMI or CVMI can replace the RUS skeletal maturity score. A total of 1017 participants were included with both hand-wrist radiograph and lateral cephalogram acquired concurrently. From the lateral cephalogram, CVMI was determined; through the hand-wrist radiograph, SMI was categorized, and the RUS skeletal maturity score was evaluated as well. Associations were examined using the Mann–Whitney U test, Spearman’s rank-order correlation analysis, and multiple correspondence analysis. There was no statistically significant difference in chronological age between males and females; however, the SMI, CVMI, and RUS skeletal maturity scores were significantly higher in females. The SMI, CVMI, and RUS skeletal maturity scores showed a statistically significant strong degree of both positive correlation and correspondence. However, a precisely corresponding RUS skeletal maturity score was difficult to obtain for a specific CVMI and SMI stage, implying the absence of a quantitative correlation. In conclusion, detailed evaluation should be conducted using the RUS skeletal maturity score, preferably in cases that require bone age determination or residual growth estimation.

Abstract Background Detection of skeletal maturity is vital in orthodontic treatment timing and planning. Traditional methods include hand-wrist radiography and cervical vertebral maturation index (CVMI). Though the radiographic methods are well established and routinely used to assess skeletal maturation, they carry the drawback of subjective perception and low reproducibility. With evolving concepts, skeletal maturation has been assessed quantitatively through biomarkers obtained from saliva, gingival crevicular fluid (GCF), and urine. The scoping review aims to explore the various biomarkers assessed through non-invasive methods and their correlation with radiographic skeletal maturity. Methodology The literature search was carried out on MEDLINE via Pubmed, Cochrane Library (Cochrane database of systematic reviews), Cochrane central register of controlled trials (CENTRAL), Google Scholar, Semantic Scholar, ScienceDirect, and Opengrey.eu for articles up to and including November 2020. Pertinent articles were selected based on inclusion and exclusion criteria. The results were tabulated based on the type of sample collected, the biomarker assessed, method of sample collection, and the radiographic method used. Results The literature search resulted in 12 relevant articles. Among all the studies, 10 studies showed that the concentration of biomarkers increases during the pubertal growth peak. On the contrary, 2 articles showed no significant difference between the levels of biomarkers and pubertal growth peak. Conclusion It can be concluded that the level of biomarkers increases during the pubertal growth spurt and can provide a quantitative way of assessing skeletal maturity.

AbstractPurposeThe study was designed to evaluate whether intrinsic morphological characteristics of the nasal dorsum are affected by cleft type, specifically cleft lip only (CL) and cleft lip with cleft palate(CL/P).Methods576 cleft patients (278 CL only, 298 CL/P), and 333 individuals without orofacial clefts were retrospectively enrolled. Lateral cephalometric radiographs of all individuals were taken to evaluate the nasal length and nasal dorsum height. Dunn’s test was used to analyze the difference (p < 0.001).ResultsIn CL and control, the angulation of the nasal bone and nasal dorsum increase by age similarly (5y-18y, p>0.05). In CL, the total dorsal length is significantly shorter (5y-18y, p<0.001). Although the upper nasal dorsum is similar (except in 5y-6y), the lower nasal dorsum is shorter (5y-18y, p<0.001).In CLP, there is no significant difference in the nasal bone angle compared with controls between 5y-7y. However, it develops insufficiently as children grow (8y-18y, p<0.001). The nasal dorsum angle is notably smaller (5y-18y, p<0.001). Nasal bone length is not significantly different from control at all stages except during ages 11y-13y (p<0.05). Total nasal dorsal length is similar to the control at skeletal maturity (17y-18y, p>0.05), although it is shorter during 8y to 16y (p<0.05). The upper nasal dorsum is overdeveloped (14y-18y, p<0.05), whereas the lower nasal dorsum is underdeveloped (5y-18y, p<0.001).ConclusionCL inhibits the growth of nasal dorsum length, leading to short nose deformity. CL/P patients are prone to saddle-nose deformity because of the diminished nasal height (decreased nasal angle).

Abstract Purpose (1) To investigate correlations between different types of FAI and the ratio of acetabular volume (AV) to femoral head volume (FV) on MR arthrography. (2) To assess 2D/3D measurements in identifying different types of FAI by means of cut-off values of AV/FV ratio (AFR). Materials and methods Alpha angle, cranial acetabular version, acetabular depth, lateral center edge angle, AV, and FV of 52 hip MR arthrography were measured. ANOVA test correlated different types of FAI with AFR. ROC curves classified FAI by cut-off values of AFR. Accuracy of 2D/3D measurements was calculated. Results ANOVA test showed a significant difference of AFR (p value < 0.001) among the three types of FAI. The mean values of AFR were 0.64, 0.74, and 0.89 in cam, mixed, and pincer types, respectively. Cut-off values of AFR were 0.70 to distinguish cam types from mixed and pincer types, and 0.79 to distinguish pincer types from cam and mixed types. Cut-off values identified 100%, 73.9%, and 55.6% of pincer, cam, and mixed types. 2D and 3D classifications of FAI showed accuracy of 40.4% and 73.0%. Conclusions 3D measurements were clearly more accurate than 2D measurements. Distinct cut-off values of AFR discriminated cam types from pincer types and identified pincer types in all cases. Cam and mixed types were not accurately recognized.

Objectives: Return to sport is a common co ncern in those undergoing arthroscopic surgery for the treatment of femoroacetabular impingement. These are commonly young active individuals with high-level athletic aspirations. Setting expectations in terms of appropriate time frame and success rates are an integral piece of pre-operative education and planning. The goals of this study were to examine return to play (RTP) rates and time frames in professional and collegiate athletes following hip arthroscopy, evaluate sex differences in return to play (morphology and rates), and evaluate differences in return to play for the most common sports. Methods: A retrospective review of a continuous cohort of patients undergoing hip arthroscopy for the treatment of femoroacetabular impingement and labral injury was conducted between January 2014 and December 2018. Athletes whom were participating in collegiate or professional sports prior to surgery were included. Chart review was conducted to gather sport specific information, morphologic data, clearance dates, successful return, and subsequent surgery. Successful return to sport was determined by being able to return to participation following clearance in at least one season. Descriptive statistics were utilized to summarize the data set and chi-square and t-tests were utilized to examine differences between groups. Results: 265 patients undergoing 332 hip arthroscopies participating in collegiate or professional sports prior to surgery were identified (75.4% male and 24.6% female), with 237 collegiate athletes and 95 professional athletes. There was a significant difference in mean alpha angles between males and females, 70.2 ± 10.5 males and 60.7± 10.0 in females, (p<0.001), but no significant differences in coronal center edge angles or femoral version. 87% of the athletes participated in hockey, football, lacrosse, soccer, baseball, soccer, or basketball. Given that a significant portion of the athletes were in college, there was a portion that graduated and thus no longer participated in collegiate athletics (27 hips), and 3 athletes (all with bilateral hip arthroscopies) were unable to return to sport due to other conditions. 91.9% of athletes were able to return to sport. 19 athletes (22 hips) were unable to return to sport. The group that was unable to return was predominantly female (73%), and this difference was significant (p<0.001). There was a significant difference between the returning group and the group that failed to return to sport in alpha angle (RTP 68.6 ± 10.8 vs No RTP 60.7± 10.6), but there were no differences in coronal center edge angle or femoral version. The difference in alpha angle is due to the predominance of females (whom had significantly lower alphas) in the unable to return group. 10 athletes (11 hips, 3.3%) required subsequent surgery (revision arthroscopy, conversion to periacetabular osteotomy, or hip resurfacing). Times for return to play were available to 205 of the athletes, averaging 6.8 months± 2.8. There was no significant difference between the males and females for return to play. There was trend towards shorter length of return for hockey athletes. There was a significant difference in the return to sport rates between the sport groups, but there were some groups with smaller sample sizes that should be taken into account. The groups with more athletes unable to return were soccer and lacrosse; these sports also had a high number of female athletes. There were no hockey athletes that were unable to return, and only 1 football athlete was unable to return. Conclusions: Hip arthroscopy for the treatment of femoroacetabular impingement and labral injury allows patients to return to sport at a high level within an average of 6.8 months. However, female athletes are less likely to have a successful return and should potentially be counseled as such. This may also inform pre-operative rehabilitation programs and intra-operative planning for female athletes. Further research should examine causes for decreased rate of return for females, and potential ways to maximize recovery and return to sport following hip arthroscopy. [Table: see text]

The Difference

Although numerous criteria have been proposed to define abnormal hip morphology, mostly used in the diagnosis of femoroacetabular impingement, it is not a practical approach to measure all of these parameters in all cases without clinical suspicion. In this study, our aim was to develop an evaluating and reporting standardization for routine hip examinations to define both hip morphology and impingement. A total of 108 patients with routine hip magnetic resonance imaging (MRI) and antero-posterior pelvic radiograph (PR) were included in this retrospective study. Alpha angle (AA), acetabular depth (AD), acetabular protrusion, acetabular anteversion, collo- diaphyseal angle (CDA), lateral center-edge angle (LCEA) and Tönnis angle (TA) were measured. The differences and associations between these parameters were evaluated according to imaging modality or plane, and sex. Although a significant difference has been found between the axial AA and the coronal AA mean values measured on MRI, there was also a strong correlation. Coronal measurements were significantly higher. AA values measured in PR and coronal MRI were comparable. Males had higher AA in both planes as compared to females. There were no significant differences between CDA values in MRI and PR. There was a significant difference and a moderate correlation between AD values in MRI and PR. We suggest that routine reports should include a measurement of AA in two planes, and measurement of CDA in PR or MRI. Due to the difference in AD between MRI and radiography, LCEA or TA may represent better alternatives. Checking for a negative Tönnis sign would represent a practical approach.

Objective. The aim was to evaluate differences in the cervical vertebral skeletal maturity of unilateral cleft lip and palate (UCLP) and non-cleft lip/palate (non-CLP) Saudi male orthodontic patients. Method. This cross-sectional multicenter study took place at the dental school, King Saud University and King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia, between October 2014 and September 2015. The records of Saudi male orthodontic patients with UCLP n=69 were collected. Cervical vertebral maturation was assessed using their cephalometric radiographs. The records of 138 age-matched non-CLP Saudi male orthodontic patients served as controls. Results. There was a significant difference in skeletal maturity between the UCLP and non-CLP groups, as evident in the delayed skeletal development among the UCLP participants. Moreover, pubertal growth spurt onset was significantly earlier in the non-cleft participants in comparison with the UCLP participants p=0.009. Conclusions. There is delayed skeletal maturity among the UCLP Saudi male population in comparison with their non-CLP age-matched peers.

Aim: This study aimed to review the clinical findings and surgical intervention of the hip fracture at the Hue University Hospital in Vietnam. Methods:The data of proximal femoral fractures was collected retrospectively. All patients, in a period of 5 years, from Jan 2008 to December 2012, suffered either from intertrochanteric or femoral neck fractures. The numbers of patients were gathered separately for each year, by age groups (under 40, 40-49, 50-59, 60-69, 70-79, older) and by sex. We analyzed what kind of treatment options were used for the hip fracture. Results:Of 224 patients (93 men and 131 women) studied, 71% patients are over 70 years old, 103 women and 56 men (p<0.05). For patients under 40 years, there were 1 woman and 11 men (p<0.05). There were 88 intertrochanteric and 136 femoral neck fractures. There was no significant difference in the two fractures between men and women. The numbers of hip fracture increased by each year, 29/224 cases in 2010, 63/224 cases in 2011, 76/224 cases in 2012. Treatment of 88 intertrochanteric fractures: 49 cases (55.7%) of dynamic hip screw (DHS), 14 cases of hemiarthroplasty (15.9%), 2 cases of total hip replacement (2.3%). Treatment of 136 femoral neck fractures: 48 cases of total replacement (35.3%), 43 cases of hemiarthroplasty (31.6%), 15 cases of screwing (11%). In cases of 40 patients (17.9%) hip fracture was managed conservatively, 23 were femoral neck fractures and 17 were intertrochanteric fractures. Conclusions: Hip fracture is growing challenge in Hue medical university hospital. The conservative approach is still high in people who could not be operable due to severe medical conditions as well as for patients with economic difficulties. Over 70% of the hip fractures in people 70+ are caused by osteoporosis. The number of hip fracture is increasing in the following years, most likely due to the increase in the prevalence of osteoporosis. Early detection and prevention of osteoporosis should be addressed, particularly in high risk population. More aggressive surgical approach should be implemented in order to improve the quality of life in patients with hip fractures. Key words:Hip fracture.

Background: Radiographic findings related to the cam and pincer variants of femoroacetabular impingement (FAI) include measurements of the alpha angle and lateral center-edge angle (LCEA). The function of these radiographic findings has been put into question because of high heterogeneity in reported studies. Purpose: The aim of this study was 3-fold: (1) to determine the prevalence of cam and pincer variants according to sex and age on anteroposterior (AP) pelvic radiographs from an asymptomatic nonathletic population, (2) to identify the most common radiographic signs of cam- and pincer-type variants, and (3) to determine if there are variations in the prevalence of these radiographic signs according to sex and age. Study Design: Cross-sectional study; Level of evidence, 3. Methods: There were 3 independent observers who retrospectively analyzed the 939 AP pelvic radiographs (1878 hips) of patients aged 18 to 50 years who did not have hip symptoms and who were not professional athletes. The prevalence of the cam and pincer variants according to the alpha angle and LCEA, respectively, and the presence of other radiographic signs commonly associated with these variables were determined in the overall population and by subgroup according to sex and age group (18-30, 31-40, and 41-50 years). Descriptive and inferential statistics were used to analyze the study sample. Results: The mean age of the included population was 31.0 ± 9.2 years, and 68.2% were male. The prevalence of the cam-type variant was 29.7% (558/1878), and that of the pincer-type variant was 24.3% (456/1878). The radiographic signs that were most associated with the cam and pincer variants were a pistol-grip deformity and the crossover sign, respectively. Significant differences ( P < .001) in the prevalence of these variants were identified between men and women in both variants. No differences were observed in the alpha angle or LCEA according to sex or age. Conclusion: Radiographic findings suggestive of FAI had significant variations with respect to sex and age in this study sample. This study provides information to determine the prevalence of these anatomic variants in the general population.

Background: Morphological changes characteristic of femoroacetabular impingement (FAI) are common in soccer players. However, the clinical relevance of such anatomical variations is still not well-defined. Hypothesis: We hypothesized that high alpha angle values and/or acetabular retroversion index (ARI) are correlated with rotational range of motion (ROM) of the hip and that there are clinical-radiological diferences between the dominant lower limb (DLL) and nondominant lower limb (NDLL) in professional soccer players. Study Design: Cross-sectional. Level of Evidence: Level 3. Methods: A total of 59 male professional soccer players (average age 25.5 years, range 18-38 years) were evaluated in the preseason. As main outcome measures, we evaluated the alpha angle and the ARI and hip IR and ER ROM with radiographic analysis. Results: The measurements taken on DLL and NDLL were compared and a significant difference was found between the sides in the ER ( P = 0.027), where the DLL measures were 1.54° (95% CI, 0.18-2.89) greater than the NDLL. There were no significant differences between the sides in the measures of IR ( P > 0.99), total ROM ( P = 0.07), alpha angle ( P = 0.250), and ARI ( P = 0.079). The correlations between the rotation measurements and the alpha angle in each limb were evaluated and the coefficient values showed no correlation; so also between the ARI and rotation measures. Conclusion: Morphological changes of the femur or acetabulum are not correlated with hip IR and ER ROM in male professional soccer players. ER on the dominant side was greater than on the nondominant side. There was no significant difference in the other measurements between sides. Clinical Relevance: In clinical practice, it is common to attribute loss of hip rotational movement to the presence of FAI. This study shows that anatomical FAI may not have a very strong influence on available hip rotational movement in professional soccer athletes.
