Double Intertrochanteric Osteotomy for Trochanteric Overgrowth and a Short Femoral Neck in Adolescents

Purpose To review the outcome of Wagner double intertrochanteric osteotomy for trochanteric overgrowth and a short femoral neck in 7 adolescents. Methods Records of one male and 6 females aged 15 to 20 years who underwent modified Wagner osteotomy for trochanteric overgrowth and a short femoral neck by a single senior surgeon were reviewed. The diagnoses were coxa vara (n=2), developmental dysplasia of the hip (n=3), Leg-Calve-Perthes (n=1), and proximal femoral focal deficiency (n=1). Radiological indication for double intertrochanteric osteotomy included a neck-shaft angle (NSA) <120° or a centre trochanter distance (CTD) <28 mm. Function was evaluated using the Children's Hospital Oakland Hip Evaluation Scale (CHOHES). The articulotrochanteric distance (ATD), CTD, NSA, and the distance between the centre of the femoral head and the centre of the acetabulum (MZ) were measured on radiographs. Results The mean follow-up duration was 61 (range, 28–86) months. The ATD improved from 16±11.5 mm to −6.3±10.2 mm (p=0.018), the CTD from 27.9±3.5 mm to 36.4±7.1 mm (p=0.018), the NSA from 112°±24.4° to 131°±16° (p=0.028), the MZ from 12.7±6.5 mm to 7.7±4.2 mm (p=0.028), and the CHOHES score from 62.1±8.7 to 84±9.6 (p=0.017). One patient had delayed union. Two patients had persistent Trendelenburg gait. Two patients declined second-stage surgery for acetabular dysplasia after solving the femoral side problems at the first stage. One of them developed hip arthrosis. Conclusion Double intertrochanteric osteotomy is a viable treatment option for adolescents with trochanteric overgrowth and a short femoral neck.

Abstract There is a lack of consensus around optimal surgical management for Legg–Calvé–Perthes Disease (LCPD). This case report discusses the benefits of combining arthroscopic femoral neck osteochondroplasty and labral repair with Morscher’s Osteotomy (MO) for LCPD. S.A. is a 17-year-old female diagnosed with LCPD at the age of 6 years and has long-standing right hip symptoms. An arthroscopic femoral neck osteochondroplasty and labral repair followed by MO was performed. The pre-operative and 8 months post-operative International Hip Outcome Tool (iHOT-12) scores were 16.3 and 79.8 out of 100, respectively, indicating better quality-of-life. Also, the femoral neck-shaft-angle (NSA) changed from 120 pre-operative to 138.7 post-operative to represent the correction of coxa vara. The literature review revealed no published reports describing combined MO with hip arthroscopic interventions in managing LCPD. Combined arthroscopic femoral neck osteochondroplasty (with labral repair) and MO provides high patient satisfaction and improves radiographic parameters in patients with LCPD.

Abstract Background When performing femoral reconstruction in patients with Crowe type IV developmental dysplasia of the hip (DDH), anatomical deformity presents many technical challenges to orthopedic surgeons. The false acetabulum is suggested to influence load transmission and femoral development. The aim of this study was to describe the morphological features of dysplastic femurs in Crowe type IV DDH and further evaluate the potential effect of the false acetabulum on morphological features and medullary canal of Crowe type IV femurs. Methods We analyzed preoperative computed tomography scans from 45 patients with 51 hips (25 hips without false acetabulum in the IVa group and 26 hips with false acetabulum in the IVb group) who were diagnosed with Crowe type IV DDH and 30 normal hips in our hospital between January 2009 and January 2019. Three-dimensional reconstruction was performed using Mimics software, and the coronal femoral plane was determined to evaluate the following parameters: dislocation height, dislocation ratio, height of the femoral head (FH), height of the greater trochanter (GT), GT–FH height discrepancy, height of the isthmus, neck-shaft angle, femoral offset and anteversion of the femoral neck. The mediolateral (ML) width, anterolateral (AP) width and diameter of medullary canal of the proximal femur were measured on the axial sections. Further, canal flare index (CFI), metaphyseal-CFI and diaphyseal-CFI were also calculated. Results Compared with the normal femurs, the Crowe type IV DDH femurs had a higher femoral head, larger GT–FH height discrepancy, larger femoral neck anteversion, higher isthmus position and smaller femoral offset. Dislocation height and dislocation rate were significantly larger in the IVa DDH group (65.34 ± 9.83 mm vs. 52.24 ± 11.42 mm). Further, the IVb femurs had a significantly lower isthmus position, larger neck-shaft angle and smaller femoral neck anteversion than IVa femurs. The ML, AP canal widths and the diameter of medullary canal in both DDH groups were significantly smaller than the normal group. Dimensional parameters of IVa femurs were also narrower than IVb femurs in most sections, but with no difference at the level of isthmus. According to the CFIs, the variation of proximal medullary canal in IVb femurs was mainly located in the diaphyseal region, while that in IVa femurs was located in the whole proximal femur. Conclusions High dislocated femurs are associated with more anteverted femoral neck, smaller femoral offset and narrower medullary canal. Without stimulation of the false acetabulum, IVa DDH femurs were associated with higher dislocation and notably narrower medullary canal, whose variation of medullary canal was located in the whole proximal femur.

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.

Objectives Fractures of the proximal femur account for less than 1% of all children's fractures. Because of this, most orthopaedic surgeons lack enough experience in treating them. This adds to the rather high incidence of complications especially nonunion. At the time of this review there is no consensus on which method of treatment of the nonunion is the best. The objective of this study is to present our method of treatment to correct the nonunion without open reduction of the nonunion sites. Method 9 children with nonunion of the proximal femur with an average age of 10.2 years (2-14 years old) were included in the study. There were 7 males and 2 females. All of them underwent at least 1 operation to treat the initial fractures and the nonunion. The nonunion in all these 9 cases was treated with valgus intertrochanteric osteotomy without open reduction of the nonunion site. The healing time of the nonunion, the postoperative neck-shaft angle and the functional outcome were evaluated. Results All the nonunion cases had coxa vara and had bone resorption of the femoral neck with x-ray evidences of avascular necrosis (AVN). Ratliff classification was used to classify the AVN, Ratliff type 3 was found in 4 cases, Ratliff 2 in 1 case and Ratliff 1 in 4 cases. Patients were followed for an average of 68 (range 36-156) months. All patients had x-ray evidence of solid union of the nonunion in an average time of 15.4 (range 13-18) weeks and union of the osteotomy sites within10.6 (range 9-12) weeks. The postoperative neck-shaft angle averaged 135° (range 125°-150°) compared to 98° before the surgery. The increase in the amount of neck-shaft angle was statistically significant (p<0.001). Using Harris Hip Score, 2 patients were graded as excellent, 3 patients were graded as good and 4 patients were graded as fair. Harris Hip Score was significantly improved compared to the preoperative status (p<0.001). Conclusions Nonunion paediatric femoral neck fracture treatment could be successfully treated without open reduction by using valgus intertrochanteric osteotomy. All patients obtained union of the nonunion site and the osteotomy site in this study. Harris Hip Score showed significant improvement. This technique can be used to treat nonunion with associated coxa vara, bone resorption and AVN with satisfactory results even in cases who had received several operations before.

Background: In the fields of forensics, anthropology, orthopaedics, and human kinematics, the thigh bone femur is widely studied. The clinical significance of the femoral neck shaft angle lies in the diagnosis, treatment and monitoring of femoral neck fractures, trochanteric fractures, slipped upper femoral epiphysis, and hip developmental dysplasia. Objective: The present study was conducted to compare the NSA disparity between femurs on both sides and to compare the NSA with the Western and Indian population sizes of different regions. This research therefore leads to Indian data on these parameters. Materials and Methods: A total of 150 (75 right and 75 left) dry femur were used for measuring the neck shaft angle. Unpaired t-test was used to compare right and left femora. Results: The mean value of neck shaft angle was 126.04±5.05°. It ranges between 1130 to 1360. The mean value of right side was 125.92±4.9° and left side was measured 127.43±5.2°. There was no significant correlation between right and left neck shaft angle. Conclusion: The mean left femoral neck shaft angle was higher than the right femoral shaft in the present analysis, but the values were not statistically important. The angle of the neck shaft was lower than most studies in the Western population, but it was similar to most other studies in India. In the Indian population, geographical variations in the angle of the neck shaft also occur. In the field of orthopaedic surgery and anthropometry, this research will be of benefit.

Background: The femoral neck-shaft angle is the measurement of the angle formed between the oblique oriented neck with the vertical shaft and is an important anatomic measurement for the evaluation of biomechanics of hip. The neck shaft angle is important in surgeries that involve the neck of femur, Intertrochanteric fractures, slipped capital femoral epiphysis, and developmental dysplasia of hip. Different variation of neck shaft angle has been seen in different literature and all the orthopedic implants are designed according to the values of the western literature which is different from the Indian subcontinent.Methods: Pelvic radiographs of patients who presented to Accident and emergency care or the outpatient department were used in the study 110 patients radiographs were assessed in the study. There were 55 males and 55 females in our study. The mean age for males was 46.5 years and that for females was 43.2 years. The pelvis radiographs were studied for neck shaft angle .The measurements were performed bilaterally on the digital screen using the PACS (picture archiving and communication system) with handheld 360 degree goniometer.Results: The mean neck shaft angle in our study was129.26 degree for males and 126.62 degree for females .The overall mean neck shaft angle in 110 radiographs was 128.60 degree. Conclusions: We conclude that consideration of neck shaft angles in orthopedics surgery and designing of implant can give more angle options for the surgeons which can improve the overall prognosis of the patient.

The Impact

Background: While the influences of acetabular dysplasia and overcoverage on hip arthritis have been studied, the impact of femoral neck-shaft angle on hip arthritis is much more poorly understood. The purpose of this study is to determine if a relationship exists between neck shaft angle and the development of osteoarthritis, a better understanding of which would be useful to surgeons planning osteotomies about the hip. Methods: 533 cadaveric femora and acetabulae (1066 total) from the Hamann-Todd Osteological Collection (Cleveland, OH) were acquired. We measured true neck shaft angle using an AP photograph with the femoral neck parallel to the table. Femoral head volume to acetabular volume ratio, representing femoral head coverage, as well as femoral version were utilised. Correlation between neck shaft angle, femoral version, femoral head coverage and osteoarthritis were evaluated with multiple regression analysis. Results: The mean age and standard deviation was 56 ± 10 years. There were 64 females (12%) and 469 males. There were 380 Caucasians (71%) and 153 African-Americans. Mean femoral version was 11° ± 12° and mean true neck shaft angle was 127.7° ± 5.9° There was a strong correlation between age and arthritis (standardised beta 0.488, p < 0.001). There was a significant correlation between increasing true neck shaft angle and decreasing hip arthritis (standardised beta -0.024, p = 0.038). In the femoral head overcoverage subset, increasing true neck shaft angle was still significantly associated with decreasing hip arthritis (standardised beta −0.088, p = 0.018), although this relationship was not significant with femoral head undercoverage subset. Conclusions: With sufficient acetabular coverage, a relative increase in femoral neck shaft angle within the physiologic range is associated with decreased hip osteoarthritis. Clinical relevance: An understanding of the relationship between femoral neck shaft angle and hip osteoarthritis could be useful for surgeons planning pelvic or proximal femur osteotomies in children.

Objective: Pediatric femoral neck fractures are uncommon injuries. Accurate early reduction and fixation is recommended to avoid serious long-term complications. The aim of this study was to analyze the clinical and radiological outcomes of 12 children with femoral neck fractures who were treated with closed reduction and cannulated screw fixation. Method: Between November 2015 and December 2019, 12 children (4 males,8 females) with an average age of 9.7 were operated by closed reduction and cannulated screw fixation for femoral neck fractures. We evaluated the medical records of all patients, including age, gender, injury mechanism, fracture type, initial displacement, postoperative reduction, follow-up roentgenograms and Ratliff’s scores. Results: The mean follow-up was 22.3 months (range 12–47 months). Six Delbett type 2, five Delbett type 3 and one Delbett type 4 fractures were operated with an avarage time to surgery of 12.5 (range: 1-75 hours). Satisfactory outcomes according to Ratliff’s criteria were obtained in 10 (%83.3) children. Coxa vara occurred in 2 cases. Any avascular necrosis was not seen during the follow-up period. Conclusion: Early closed reduction and cannulated screw fixation may be effective to avoid long-term complications in pediatric femoral neck fractures.

BACKGROUND The peculiar waddling gait of a female attracts most of the anatomists to measure and compare the neck-shaft angle (NSA) of the femora. The femoral neck shaft angle is greater in women due to greater pelvic breadth and shorter femur. Neck-shaft angle was measured by the angle that the neck makes with the shaft of the femur and it is measured on the ventral surface of femur taking the long axis of femoral neck with the long axis of the proximal end of the femur. It gives information about the race it belongs to and normally measures 120° to 140°. The intention of this study was to establish the femoral neck shaft angle variations in adult male and female for medico-legal and anthropometric studies. METHODS This cross-sectional study was conducted on 84 adult human femora of unknown sex in the anatomy department, Sriram Chandra Bhanja (SCB) Medical College, Cuttack, Odisha, from May 2018 to April 2019. We included all the femora which were free of damage or deformity and fully ossified indicating adult bone. Femora with any pathological changes i.e., cortical bone deterioration, extreme osteophyte activity, osteoarthritis and fracture etc. were excluded from the study. The NSA was measured by protractor and goniometer. RESULTS In the present study the NSA range for the right femur of male was 108° - 135° and for the right femur of females 117° - 135°. The left male femur was 118° - 135° and the left female femur was 120° - 135°. The mean neck shaft angle of male femora was 125.9° and the female femora was 125.7°. These measurements show that the values were more in males than the females. The value of the present study was statistically significant between male and female i.e., P < 0.0001. CONCLUSIONS These measurements are important in the medico-legal cases, reconstructive orthopaedic surgeries, hip replacement surgeries and also while constructing suitable prosthesis. This will also be helpful in the detection of sex by anatomists and forensic experts. KEY WORDS Neck Shaft Angle, Medico-Legal, Anthropometry and Goniometer
