Background: Femoral neck-shaft angle has its importance in describing biomechanics of hip. Measurement methods like plain radiography and CT scans have its limitations. The modied neck-shaft angle (mNSA) drawn on MRI scans is less susceptible to rotational effects and is more reliable for getting normal values. The present study was undertaken to assess the neck shaft angle on MRI and establish differences according to age and gender. Methods: Total 200 adults were recruited and equally distributed under four study cohorts according to age and gender. MRI of hip joint was analysed and mNSA was measured using pre-dened axial lines and landmarks. Results: The mean age of the participants was 49.76±18.184 years (18 to 87 years). The mean mNSA was 147.855o. Males had signicantly higher mean mNSA (149.93±6.61)o than females (145.78±5.71)o. Though the younger age group (<60 years) had higher mNSA values (148.32±6.65) than older (> 60years) age group (147.3900±6.35), the difference was not statistically signicant. Conclusions: We conclude that gender-based variation exists in the population with the higher values of mNSAin males as compared to females in any age group. The age based difference is also present, but it is not signicant. Neck shaft angle calculated on the MRI has the advantage that it is unaffected by rotation of the hip and is radiation free. The orthopaedic surgeons can use the mNSAfor the diagnosis and planning surgeries around hip, for designing implants and prosthesis. It can also be of help for the forensic anthropologists and to the anatomists. Multicentric studies may be undertaken to include a larger population.

Objectives: The objective of our study was to examine the changes in the inclination and Alsberg angles of the femur in terms of age and gender. Methods: The present study was conducted on X-Ray images of 208 healthy individuals (103 males and 105 females) admitted to Bolu Abant Izzet Baysal University, Orthopedics and Traumatology Clinics. Both genders were separated into 3 different age groups. Statistical analyses were made to determine the difference between the gender and age groups. Results: The mean inclination angle of the femur was 132.88±7.08º on the right-side and 130.27±7.81º on the left. The mean Alsberg angle of the femur was 42.07±7.04º on the right-side and 41.43±7.03º on the left. The inclination angle was significantly higher in males than females on both sides and was significantly lower in 41–60 age group. The Alsberg angle was also significantly higher in males than females in 21–40 age group. Conclusion: The Alsberg angle is positively related with inclination angle, and subject to change by age. Knowing how IA and AA will be affected by age and gender and knowing the relation between these two angles will help to take a more accurate approach while evaluating and managing the follow up of a patient undergoing total hip arthroplasty, reconstructive surgery or planning physical theraphy.

Cervical lesions are often characterized by defects seen in the gingival third of a tooth crown which may be in the facial or lingual surface. Pathological loss of tooth structure caused by factors other than dental caries such as cervical abrasion is referred to as non-carious cervical lesions (NCCL). Cervical abrasion is an example of NCCL in which a constant exposure of the tooth to mechanical forces leads to pathological wearing away of the hard tissues. In most of the cases, cervical tooth lesions are revealed to be more common as the age increases. Several studies have reported the difference in the prevalence of cervical abrasion between males and females. Many reports suggest that cervical abrasion is commonly associated with improper tooth brushing habits. To evaluate the prevalence of cervical abrasion between genders and its influence on age. It is a retrospective study conducted using the case records of Saveetha Dental College and Hospital, Chennai, India from June 2019 to March 2020. Data including the patient’s name, patient’s identification number (PID), age, gender and presence of cervical abrasion were retrieved from the patients’ case records. A total of 742 consecutive case records were retrieved and analysed. Cervical abrasion was observed in 371 individuals of this study. High prevalence of cervical abrasions was seen in males (70.9%) compared to females (29.1%). Most of the cases were observed in individuals within the 41-50 years age group (28.8%), and the least was seen within the 11-20 years age group (0.3%). Within the limits of the study, most of the cervical abrasion cases are recorded in individuals within the 41-50 years age group with higher predilection in males. There is a statistically significant association of cervical abrasion with age and gender.

Background: Femoral neck fracture nonunion is a frequent and challenging complication, with several surgical options. Objectives: The present study reported the outcome of valgus osteotomy for treating femoral neck nonunion in patients aged <65 years. Methods: This case series research included young patients who underwent valgus osteotomy for treating femoral neck nonunion or device failure of the index surgery. The fixation of the osteotomy site was performed using either a dynamic hip screw or a fixed angle blade. The union of the neck and osteotomy site (subtrochanteric region) was evaluated by monitoring callus formation in the postoperative radiographs. Limb length discrepancy, Pauwels’ angle, and the neck-shaft angle were evaluated before the surgery and at the last follow-up. Postoperative complications were extracted from the explored patients’ profiles. Results: Twenty patients with a Mean±SD age of 27.2±10.8 years were examined in this study‎. The Mean±SD follow-up time of the patients was 6.1±3.9 years. The femoral neck was united in 18 patients in a Mean±SD period of 5.1±2.3 months. The Mean±SD limb length discrepancy was measured as 1.3±0.8 cm before and 0.5±0.7 cm after the ‏osteotomy. The Mean±SD Pauwels’ angle was calculated as 65.5±16.9º before and 32.4±16.2º after the osteotomy. The Mean±SD neck-shaft angle was computed to be 121.9±22.8º before and 144.5±17.7º after the osteotomy. Revision surgery was performed for 6 (30%) patients. This measure included device removal in 4 and total hip arthroplasty in 2 patient. Conclusion: Valgus osteotomy is a safe and efficient technique for managing femoral neck nonunion. Therefore‎, this approach is suggested as a good alternative for total hip arthroplasty, particularly in young and active patients‎.

AimsIn patients where the proximal femur shows gross deformity due to degenerative changes or fracture, the contralateral femur is often used to perform preoperative templating for hip arthroplasty. However, femurs may not be symmetrical: the aim of this study was to determine the degree of variation between hips in healthy individuals and to determine whether it is affected by demographic parameters.Materials and MethodsCT-scan based modelling was used to examine the pelvis and bilateral femurs of 345 patients (211 males, 134 women; mean age 62 years (standard deviation (sd) 17), mean body mass index 27 kg/m2(sd 5)) representing a range of ethnicities. The femoral neck-shaft angle (NSA), femoral offset (FO), femoral neck version (FNV), femoral length (FL), femoral canal flare index (fCFI), and femoral head radius (FHr) were then determined for each patient. All measurements were constructed using algorithm-calculated landmarks, resulting in reproducible and consistent constructs for each specimen. We then analyzed femoral symmetry based on absolute differences (AD) and percentage asymmetry (%AS) following a previously validated method.ResultsWe found an asymmetry > 2% for NSA (mean AD 2.9°, mean %AS 2.3; p = 0.03), FO (AD 3.8 mm, %AS 9.1 ; p = 0.01), FNV (AD 5.1°, %AS 46.7 ; p = 0.001) and fCFI (AD 0.2 mm, %AS 5.4 ; p = 0.7). Significant relationships were found for AD regarding NSA and ethnicity (p = 0.037), FL and height (R2 = 0.22), and fCFI and gender (R2 = 0.34).ConclusionOur data confirm the presence of asymmetry of proximal femurs, which is mostly independent of demographic parameters. In cases where contralateral templating is used, such asymmetry may lead to inaccurate anatomical restoration of the hip if the templated sizes are routinely implanted. However, the clinical impact cannot be determined from our investigation. Cite this article: Bone Joint J 2018;100-B:839–44.

Background. The femoral neck-shaft angle (NSA) is of high importance for the diagnostics and treatment of various conditions of the hip. However, rotational effects limit its precision and applicability using plain radiographs. This study introduces a novel method to measure the femoral NSA: the modified NSA (mNSA), possibly being less susceptible against rotational effects compared to the conventional NSA.Patients and Methods. The method of measurement is described and its applicability was tested in 400 pelvis computed tomography scans (800 hips). Age- and gender-dependent reference values are given and intra- and interrater reliability are analyzed.Results. The mean age of all 400 patients (800 hips) was 54.32 years (18–100, SD 22.05 years). The mean mNSA was 147.0° and the 95% confidence interval was 146.7°–147.4°. Differences of the mNSA between sexes, age groups, and sides were nonsignificant. The absolute difference between NSA and mNSA was 16.3° (range 3–31°; SD 4.4°); the correlation was high (0.738;p<0.001). Overall, the intra- and interrater reliability were excellent for the mNSA.Interpretation. We introduced a novel concept for the analysis of the neck-shaft angle. The high reliability of the measurement has been proven and its robustness to hip rotation was demonstrated.

Background : The angle of inclination of the femur is the angle formed between long axis of neck of femur and long axis of the shaft of femur. The average angle of inclination (neck–shaft angle) is 126°, ranging from 115° to 140° in the adult population. As with the angle of inclination of the humerus, the angle of inclination of the femur varies among individuals and also from side to side. The aim of this study was to determine the Angle of inclination and neck length of Femur.Material & Methods: A total of 50 dry femora (25right and 25 left) of nobel medical college was cross sectionally studied with random sampling without knowing the sex & age of bone. The angle formed between long axis of neck and long axis of the shaft of femur was measured with the help of goniometer. The neck length was measured with the help of sliding calliper.Results: The mean angle of inclination was 128.98±4.55 degrees, on the right side was129.84±5.22 degrees and on the left side was 128.12±3.66degrees. The difference in the mean angle of inclination of right and the left side was found to be statistically insignificant (p value> 0.05). The mean neck length femur was 2.93 ±0.24cm, right femur was 3.06±0.19cm and left femur was 2.80±0.21cm. The difference in the mean neck neck length of the right and the left side was found to be statistically insignificant (p value> 0.05).Conclusion: The Angle of Inclination of Femur and neck length of femur in present study had no remarkable dissimilarity with the results observed in the studies conducted in Nepal and neighbouring countries. In the study there was no statistical significant difference between the neck-shaft angle and neck length of femur of right and left side of the femur but there was positive correlation between angle of inclination and neck length of femur.Journal of Nobel Medical CollegeVolume 6, Number 1, Issue 10 (January-June, 2017), Page: 44-47
