Neck Fractures In Young Adults Research Articles

Comparison of daytime and after-hours surgical treatment of femoral neck fractures.

The timing of surgery for femoral neck fractures in young adults remains controversial. Nonetheless, the debate continues about whether orthopedic trauma cases should be operated daytime or after hours. This study compared the clinical and radiological outcomes of surgery on femoral neck fractures during daytime versus after-hours. A total of 124 patients aged 18-60 years who were operated for femoral neck fractures between 2015 and 2020 were included in the study. The patients were separated into two groups. Seventy-two patients operated between 08:00 and 17:00 hours were defined as the daytime group and 52 patients operated between 17:01 and 07:59 hours were defined as the after-hours group. Demographic data, reduction quality, duration of operation, intraoperative estimated blood loss (EBL), postoperative complications, revision rates, and postoperative Harris hip score results of the two groups were recorded for analysis. There was no significant difference between the groups in terms of age, gender, body mass index, smoking, fracture type and follow-up time, reduction quality, postoperative complication rates, revision rates, and Harris hip score results. Waiting times until surgery, operation duration, and intraoperative EBL amounts were, in the daytime group, significantly higher than in the after-hours group. In this study comparing femoral neck fractures operated on daytime and after-hours in adults, the waiting time until surgery was found to be higher in the daytime group. Operation duration and EBL were higher in the after-hours group.

Evaluation of a Locking Autocompression Screw Model in Pauwels Type-3 Femoral Neck Fracture: In Vitro Analysis.

Femoral neck fractures in young adults are uncommon, resulting from high-energy trauma. Despite their infrequency in this population, there is higher rate of complications, especially in the more vertical fracture line, classified by Pauwels as a type-3 femoral neck fracture. The implant type is of paramount importance for maintaining anatomical reduction, since it must resist the deforming forces that act on the fracture. We comparatively evaluated two constructions of the novel locking autocompression implant (X-PIN and X-PIN+P) using the finite element method and previously established methods for treating Pauwels type-3 femoral neck fractures. Six fixation models were developed for the study: a dynamic hip screw (DHS), a DHS with an anti-rotation screw (DHS+P), the inverted triangle multiple cannulated screws construction (ASNIS), the multiple cannulated screws in an L-configuration (L), and the two models of the novel locking autocompression screw (X-PIN and X-PIN+P). Under the same conditions with a load of 2100 N, the following parameters were evaluated using SIMLAB® software: the main maximum (Max P), main minimum (Min P), localized maximum P1 (Max P1), localized maximum P2 (Max P2), total displacement, localized displacement, rotation displacement, and von Mises stress. Compared to the DHS+P and ASNIS models, the X-PIN+P model presented, respectively, increases of 51.6% and 64.7% for Max P, 85% and 247% for Min P, and 18.9% and 166.7% for von Mises stress. Max P1 did not differ between the models, but Max P2 was 55% and 50% lower for X-PIN+P than ASNIS and L, respectively. All displacement values were lower for X-PIN+P than the other models. In this FEM testing, the X-PIN+P was superior to the other models, which was due to improvement in all parameters of stress distribution, displacement, and von Mises stress compared to models using a lateral plate (DHS and DHS+P) or not (ASNIS and L).

Biplane double supported screw fixation for femoral neck fracture in young adults: A prospective cohort study

IntroductionAchieving accurate anatomic reduction and stable internal fixation is mandatory in the management of femoral neck fractures (FNF) in adults. The spatial configuration and direction of the screws have been reported to provide stability to the fracture. The study's goal is to analyse the clinico-radiological outcome of the newer biplane double-supported screw fixation (BDSF) technique in the Indian cohort. Materials and methodsPatients with isolated FNFs underwent osteo-synthesis by BDSF technique. Radiological outcome was evaluated by time to union and fracture healing on plain radiographs. Clinical outcome was measured using the Harris hip score (HHS) at 1, 3, 6, and 12 months after surgery. The pain reduction was measured using the VAS score. ResultsTwenty-seven patients with a mean age of 37.33 ± 9.84 years (24–55 years) were followed up for at least 12 months (12–31 months). The mean HHS at 12 months was 94.81 ± 8.18 (range: 68–100). Twenty-five patients were able to achieve radiological union within a mean time of 14.60 ± 4.69 weeks (range: 8–28). The overall complication rate was found to be 18.51% (5 out of 27 patients). Individual complications were non-union (2 patients; 7.4%), AVN (3 patients; 11.11%), and screw back out with femoral neck shortening (4 patients; 14.81%). ConclusionScrew configuration using the BDSF technique provides a good union rate with minimum complications. The majority of patients resulted in a good (HHS >80) to excellent functional outcome. Based on the clinico-radiological outcome obtained, we conclude that this technique is effective in the fixation of FNF in adults. Level of studyLevel II.

Biomechanical comparison of the femoral neck system and the dynamic hip screw in basicervical femoral neck fractures

The purpose of this study was to compare the fixation stability of proximal fragments and the mechanical characteristics in proximal femur models of basicervical femoral neck fracture fixed by the femoral neck system (FNS) versus the dynamic hip screw. The mean axial stiffness was 234 ± 35 N/mm in the FNS group and 253 ± 42 N/mm in the DHS group, showing no significant difference (p = 0.654). Mean values for x-axis rotation, y-axis rotation, and z-axis rotation after cycle load were 2.2 ± 0.5°, 6.5 ± 1.5°, and 2.5 ± 0.6°, respectively, in the FNS group and 2.5 ± 0.7°, 5.8 ± 2.1°, and 2.2 ± 0.9°, respectively, in the DHS group, showing no significant differences (p = 0.324, p = 0.245, and p = 0.312, respectively). The mean values of cranial and axial migration of screws within the femoral head were 1.5 ± 0.3 and 2.1 ± 0.2 mm, respectively, in the FNS group and 1.2 ± 0.3 and 2.4 ± 0.3 mm, respectively, in the DHS group, showing no significant differences (p = 0.425 and p = 0.625, respectively). The average failure load at vertical load was 1342 ± 201 N in the FNS group and 1450 ± 196 N in the DHS group, showing no significant difference (p = 0.452). FNS fixation might provide biomechanical stability comparable to that of DHS for treating displaced basicervical femoral neck fractures in young adults.

Fixator-Assisted Nailing for Femur Neck Fracture Nonunion: A Case Series Study.

Background Femoral neck fractures in young adults tend to be a result of high-energy trauma with a common pattern of Pauwels type III fracture, and they require timely and meticulous diagnosis and management. The objective of this study was to assess the clinical and radiological outcomes of the fixator-assisted nailing technique for managing femur neck fracture nonunion. Methods. This was a case series study of 16 patients with nonunion femoral neck fractures treated via a fixator-assisted nailing technique. Our inclusion criteria comprised the inclusion of any patient between the ages of 14 and 60 years old with a neglected neck of femur fracture or nonunion of the femur neck. In addition, we only included patients without further posttreatment trauma and without known metabolic diseases. The conditions that were excluded from this study included hip joints with preexisting osteoarthritis, radiographic evidence of avascular necrosis of the femoral head, and associated ipsilateral acetabulum fracture or fracture-dislocation. The fracture characteristics that were selected for the fixator-assisted nailing (FAN) technique were clear signs of pseudoarthrosis (such as sclerosis, clear fracture line defects, and failure of implants), in addition to evidence of varus malalignment. All fractures were Pauwels type III. Radiographs of the pelvis with both hips and a posteroanterior (PA) view of the injured hip were taken. Full weight bearing was allowed in all the patients from the first day postoperatively. Physical therapy was started for pain reduction modalities, stretching, and abductor strengthening. Results Union of the femur neck fracture and osteotomy site was achieved in all patients. An excellent functional status after four months of follow-up was found based on a modified Harris hip score questionnaire. At follow-up, no patient was suffering from pain or flexion contracture. Preoperative limb length discrepancy (LLD) (cm) was 1.8 ± 0.8 cm and postoperative was 0 ± 0.1 cm, p < 0.001. Preoperative neck-shaft angle (NSA) (o) was 85.6 ± 4.4 and postoperative was 126.9 ± 2.5, p < 0.001. Preoperative Pauwels angle (o) was an average of 50.4 ± 5.9 and postoperative was 31.3 ± 2.5, p < 0.001. Conclusion Our study indicates that FAN has a high success rate in young patients with nonunited femoral neck fractures.

The effect of anteromedial support plate with three cannulated screws in the treatment of Pauwels type III femoral neck fracture in young adults.

This study is aimed to evaluate the clinical effects of anteromedial support plate combined with three cannulated screws on Pauwels type III femoral neck fractures in young adults. We conducted a retrospective study of 27 patients with Pauwels type III femoral neck fracture treated by anteromedial support plate combined with three cannulated screws. The results of fracture healing and complications for all patients were assessed by postoperative imaging examination. The Harris hip score was used to evaluate the functional outcome of the hip at the last follow-up. The fracture union was achieved in 25 patients (92.6%). However, two patients required reoperation (two for nonunion). Early implant failure occurred in one patient, neck shortening in one patient and coxa vara in one patient. The excellent or good outcome of the Harris hip score was 96% for the 25 patients with satisfactory fracture union. Our preliminary results indicate that anteromedial support plate combined with three cannulated screws is a good alternative in the treatment of Pauwels type III femoral neck fractures in young adults with high union rate and low incidence of complications including nonunion and avascular necrosis of the femoral head.

Medial Locking Plate Can Increase the Fixation Stability of Vertical Femoral Neck Fracture in Young Adults?

Vertical femoral neck fractures in young adults are usually caused by a high-energy trauma. These injuries are difficult to stabilize due to significant shear forces acting on the fracture site. Their treatment is challenging and has a high risk of complications, such as fixation failure, malunion, nonunion and avascular necrosis of the femoral head. In recent years, several studies have focused on the use of direct reduction of vertical femoral neck fractures in young adult patients. This technique allows for anatomical reduction as well as the placement of an intra-articular implant to avoid shear forces at the fracture site. The aim of this study was to evaluate, based on in vitro experimental tests, the biomechanical stability provided by three different fixation methods: (i) dynamic hip screw with derotation screw, (ii) cannulated screws with a conventional medial bone plate and (iii) cannulated screws with a locked medial bone plate. For the biomechanical tests, these techniques were applied to reduce the vertical osteotomy performed on synthetic bones for later verification of the mechanical behavior under axial cyclic loading and destructive axial loading. There were no statistical differences in stiffness, micromovement displacement and mechanical strength during the biomechanical comparison of the fixation methods. Therefore, we conclude that the use of a conventional medial bone plate associated with cannulated screws, with a transverse trochanteric screw, supports the mechanical demand while the fracture is healing and this option can be used to stabilize vertical femoral neck fractures in young patients.

A Comparative Study between Proximal Femoral Locking Plate and Multiple Cannulated Screws for Fixation of Femoral Neck Fractures in Young Adults.

Objective To compare the clinical effect of proximal femoral locking plate (PFLP) versus multiple cancellous screw (MCS) for FNF. Methods FNF patients were treated with the PFLP implant or multiple cancellous screws (MCSs). Patient has been followed up for at least 12 months after surgery nonunion, and the occurrence of complications, femoral neck shortening, fracture healing time, and Harris hip score were recorded and compared. Results 77 FNF patients were treated with the PFLP (36 patients) or MCS (41 patients). The sex, age, side of the injured limb, type of Garden fracture, time from injury to surgery, and fracture healing time of two groups patients were comparable. The operation time and intraoperative blood loss in the PFLP group were worse than those in the MCS group. Two patients with the PFLP (5%) and nine patients (21%) with the MCS experienced cut out of the lag screw or avascular necrosis of the femoral head or nonunion and received hip replacement. However, the number of fluoroscopies in the PFLP group was significantly lower than that in the MCS group. Additionally, the femoral neck shortening and Harris hip score were all strongly better in the PFLP group than in the MCS group. Conclusions Compared with the MCS, PFLP treatment for FNF in young adults can decrease the fluoroscopy times, improve hip functional recovery, and reduce the complications rate and femoral neck shortening.

Effectiveness analysis of medial buttress plate augmented hollow lag screws fixation in combination with sartorius pedicled iliac flap for the treatment of femoral neck fractures in young adults

To evaluate the effectiveness of medial buttress plate augmented hollow lag screws fixation in combination with sartorius pedicled iliac flap for the treatment of femoral neck fractures in young adults. The clinical data of 11 young adult patients with femoral neck fractures between February 2013 and February 2019 were analyzed retrospectively. There were 7 males and 4 females with a mean age of 45 years (range, 32-58 years). Fractures were caused by falling from height in 6 cases, by traffic accident in 4 cases, and by sports injury in 1 case. There were 7 cases in the left hip and 4 cases in the right hip. The mean Pauwels angle was 64° (range, 55°-75°). All patients were treated by medial buttress plate augmented hollow lag screws fixation and sartorius pedicled iliac flap. The X-ray film of pelvis, lateral X-ray film of hip joint, CT scan and three-dimensional reconstruction of hip joint were taken after operation to assess fracture healing and position of the internal fixators. The postoperative hip function was evaluated according to the Harris score. All the incisions healed by first intention, and no complication such as incision infection and lateral femoral cutaneous nerve injury happened. Re-examination on the second day after operation showed that reduction and fixation of fractures was good. All patients were followed up 18-36 months (mean, 29 months). All fractures achieved bony union. The time of bony union was 16-23 weeks, with an average of 18.2 weeks. One patient (9.1%) got osteonecrosis of the femoral head (ONFH) at 30 months after operation. At last follow-up, Harris score was used to evaluate hip joint function, 9 cases were excellent, 1 case was good, 1 case was fair, and the excellent and good rate was 90.9%. Medial buttress plate augmented hollow lag screws fixation in combination with sartorius pedicled iliac flap for the treatment of femoral neck fractures in young adults has the advantage of strong biomechanical stability and can effectively improve the blood supply of femoral head and neck, which subsequently reduce the incidence of ONFH. However, the surgical indication should be fully considered.

Clinical Effect of Open Reduction and Internal Fixation for Femoral Neck Fracture in Young Adults and Related Factors of Femoral Head Necrosis.

Objective The purpose of this article is to analyze the clinical effect of open reduction and internal fixation on femoral neck fracture in young adults and to explore the related factors of femoral head necrosis. Methods The subjects were young and middle-aged femoral neck fracture patients admitted to our hospital from July 2019 to July 2021. 90 patients were randomly divided into two groups according to different treatment methods. The control group (n = 45) was treated with open reduction and internal fixation with hollow nails, while the observation group (n = 45) was treated with closed reduction and internal fixation with hollow nails. The clinical effects and adverse reactions of the two groups and the risk factors of avascular necrosis of femoral head were analyzed. Results Compared with the control group, the operation time of the observation group was significantly shortened (P < 0.05), the amount of bleeding during the operation was significantly reduced (P < 0.05), and the incidence of total adverse reactions was significantly reduced (P < 0.05). The HSS score and Harris score of the two groups were significantly decreased after treatment (P < 0.05), but there was no significant difference in the above scores between the two groups before and after treatment (P > 0.05). The related risk factors of necrosis included gender, Garden classification, time from injury to operation, and time of weight bearing after operation (P < 0.05) but not related to age and cause of injury (P > 0.05). Conclusion Open and closed reduction and internal fixation can effectively treat femoral neck fracture in young adults. The risk factors of adverse reactions of osteonecrosis include gender, Garden classification, time from injury to operation, and weight-bearing time after operation.

Prospective Study of Osteosynthesis with Fibular Bone Grafting and hip Screw Fixation for Late Femoral Neck Fracture in Young Adults

Background: Intracapsular fracture neck femur has always presented great challenges to orthopedic surgeons and still it continues to be a burning problem; thus, it is often called as an unsolved fracture. The femoral neck fracture is probably the fracture for which there exists the largest number of methods of osteosynthesis. The above quotation reflects the defeatist attitude that has long been held by medical and lay personal toward femoral neck fractures. Materials and Methods: The study was conducted in F.H. Medical College and Hospital, Agra. The cases of this study were selected from the patients attending the outpatient Department of Orthopaedics and from those arriving at the Emergency Department of F.H. Medical College and Hospital, Agra from November 2017 to December 2020. A total of 64 young adults with femoral neck fracture treated by a fibular bone graft with hip screw fixation were included in the study. All the fractures were more than 3 weeks old. Each patient was subjected to detailed clinical and radiological examination along with routine pathological investigations. Result: Results were assessed in 60 patients, whereas 4 patients were excluded from the study due to loss of follow-up. In the subcapital type, 33.3% of cases were found to have good score, 44.4% of cases had fair score, and rest of the cases were found to have poor score. In the transcervical type, 57.4% of cases scored good, 36.1% cases scored fair, and rest of the cases scored poor. In the basal type, 100% of cases were found to have good score. Therefore, transcervical and basal types of fractures have a good prognosis as compared with the subcapital type. The average follow-up was 16.4 months. Out of 60 patients assessed clinico-radiologically. Conclusion: We conclude that treatment of late femoral neck fracture is a simple and cost-effective procedure in young adults with good results.

A STUDY TO EVALUATE CLINICAL OUTCOMES IN PATIENTS OF AGE BELOW 50 YEARS WITH INTRACAPSULAR FRACTURE OF NECK OF FEMUR TREATED BY CANNULATED CANCELLOUS SCREW FIXATION

Intracapsular femoral neck fractures are commonly seen in the elderly population after a trivial fall. However, femoral neck fractures in adults younger than 50 are uncommon and often result from high-energy trauma. They account for only 2-3% of all femoral neck fractures. It is crucial to understand and contrast the differences between elderly and young adult patients to evaluate and treat femoral neck fractures. Characteristic differences are seen for the osseous and vascular anatomy, the mechanism of injury, associated injuries, fracture pattern, and treatment goals. Femoral neck fractures in young adults are associated with higher incidences of femoral head osteonecrosis and nonunion. The rate of osteonecrosis reported in the literature ranges from 12-86% in young patients after femoral neck fracture. This devastating complication may lead to the collapse of the femoral head and subsequent osteoarthritis. Reoperation and salvage procedures such as osteotomy have high failure rates, and arthroplasty procedures are not ideal given the young age and higher activity levels. This study attempts to evaluate the internal xation of intracapsular fracture of the neck of the femur with multiple cannulated cancellous lag screws. Patients selected for this surgery were between 15 to 50 years old with intracapsular fracture of neck of femur who were admitted and treated in Kurnool Medical College and Hospital, Kurnool, A.P., from October 2019 to October 2021.

Mapping of Vertical Femoral Neck Fractures in Young Patients Using Advanced 2 and 3-Dimensional Computed Tomography.

To better describe the pathoanatomy of young patients' femoral neck fractures with the goal of improving surgeons' decisions for treatment including reduction and fixation. This is a retrospective study of patient records, plain radiographs, and the modern computed tomography scans to study the pathoanatomy of Pauwels II and III femoral neck fractures (coronal angle >30 degrees) in young adults. One American College of Surgeons Level 1 trauma center. All patients 18-49 years of age with a surgically repaired Pauwels' II and III (>30 degrees) femoral neck fracture between 2013 and 2017. Fifty-six adult patients younger than 50 years were identified with a femoral neck fracture in the study period, of whom 30 met study criteria. We evaluated plain radiography and computed tomography data including fracture orientation, characteristics of fracture morphology including size, shape, and dimensions, comminution, displacement, and deformity. Fracture morphology typically included a wide-based caudal head-neck segment (80%) that ends at a variable location along the medial calcar, sometimes as caudal as the lesser trochanter. Comminution was present in 90% of cases mostly located in the inferior quadrant, but anterior or posterior to the void left by the head-neck's caudal segment. The fractures orientations and deformities were reported by means and ranges. We investigated and reported on the pathoanatomy of high-energy femoral neck fractures in young adults with the goal of increasing understanding of the injury and improving surgeons' ability to provide for improved treatment decisions and quality fracture repair.

Comparison of the clinical efficacy of a femoral neck system versus cannulated screws in the treatment of femoral neck fracture in young adults

BackgroundTo compare the clinical efficacy of a femoral neck system (FNS) and cannulated screws (CS) in the treatment of femoral neck fracture in young adults.MethodsData from 69 young adults, who were admitted for femoral neck fracture between March 2018 and June 2020, were retrospectively analyzed. Patients were divided into two groups according to surgical method: FNS and CS. The number of intraoperative fluoroscopies, operative duration, length of hospital stay, fracture healing time, Harris score of hip function, excellent and good rate of hip function, and postoperative complications (infection, cut out the internal fixation, nail withdrawal, and femoral neck shortening) were compared between the two groups. Hip joint function was evaluated using the Harris Hip Scoring system.ResultsAll 69 patients had satisfactory reduction and were followed up for 12–24 months, with a mean follow-up of 16.91 ± 3.01 months. Mean time to fracture healing was13.82 ± 1.59 and 14.03 ± 1.78 weeks in the FNS and CS groups, respectively. There was a statistical difference in the number of intraoperative fluoroscopies between the 2 groups (P = 0.000). There were no significant differences, in operation duration, hospital length of stay, fracture healing time, complications, Harris Hip Score for hip function and excellent and good rate between the two groups (P > 0.05). The incidence of complications was 6.1%(2/33) in the FNS group lower than 25%(9/36) in the CS group, a difference that was statistically significant (P = 0.032). At the last follow-up, the Harris Hip Score of the hip joint in the FNS group was 90.42 ± 4.82and 88.44 ± 5.91 in the CS group.ConclusionsBoth treatment methods resulted in higher rates of fracture healing and excellent hip function. Compared with CS, the FNS reduced the number of intraoperative fluoroscopies, radiation exposure to medical staff and patients, and short-term complications including femoral neck shortening and bone nonunion.

Bilateral femoral neck fracture following a convulsion in the presence of chronic kidney disease. A case report.

Introduction and importanceBilateral femoral neck fractures in young adults are a rare entity. It is usually associated with pre-existing metabolic diseases, such as osteoporosis, renal osteodystrophy, or hypocalcemic seizures. Hence, it is essential in such cases to look for other associated injuries following a traumatic event. Missing associated injuries may lead to significant morbidities and poor functional outcomes.Case presentationA 37 years old male, who had chronic renal failure secondary to hypertension, and presented to the emergency room following a seizure episode, in which he developed a generalized tonic-clonic convulsion secondary to electrolyte imbalances with metabolic acidosis. As a result, he developed bilateral neck of femur fracture.Intervention and outcomeThe medical team optimized electrolytes imbalance and then the patient underwent surgical stabilization of both femur neck fracture, 1 year following the surgical fixation the patient had full range of motion of both hips with radiological evidence of complete healing of the fracture.ConclusionIn cases of fractures secondary to metabolic conditions, bilateral femoral neck fractures should be suspected and investigated; especially in young patients who develop a generalized tonic-clonic seizure. The etiology is multifactorial, and the treating surgeon should be aware of predisposing factors which may affect bone quality, thereby raising the risk of fractures even with low-energy atraumatic events. Hip preservation should always be the primary target when treating these patients.

Smith-Petersen Versus Watson-Jones Approach Does Not Affect Quality of Open Reduction of Femoral Neck Fracture.

To compare immediate quality of open reduction of femoral neck fractures by alternative surgical approaches. Retrospective cohort study. Twelve Level 1 North American trauma centers. Eighty adults 18-65 years of age with isolated, displaced, OTA/AO type 31-B2 or -B3 femoral neck fractures treated with internal fixation. Thirty-two modified Smith-Petersen anterior approaches versus 48 Watson-Jones anterolateral approaches for open reduction performed by fellowship-trained orthopaedic trauma surgeons. Reduction quality as assessed by 3 senior orthopaedic traumatologists as "acceptable" or "unacceptable" on AP and lateral postoperative radiographs. No difference was observed in the rate of acceptable reduction by modified Smith-Petersen (81%) versus Watson-Jones (81%) approach (risk difference null, 95% confidence interval -17.4% to 17.4%, P = 1.00) with 90.4% panel agreement (Fleiss' weighted κ = 0.63, P < 0.01). Stratified analyses did not identify a significant difference in the rate of acceptable reduction between approaches when stratified by Pauwels angle, basicervical or transcervical fracture location, or posterior comminution. The Smith-Petersen approach afforded a better reduction when preoperative skeletal traction was not applied (RR = 1.67 [95% CI 1.10-2.52] vs. RR = 0.87 [95% CI 0.70-1.08], P = 0.006). No difference was observed in the quality of open reduction of displaced femoral neck fractures in young adults when a Watson-Jones anterolateral approach versus a modified Smith-Petersen anterior approach was performed by orthopaedic trauma surgeons.

Outcomes of Femoral Neck Fractures in Young Patients and the Factors Associated With Complications: A Multicenter Study From Malaysia.

Background and objectiveFemoral neck fractures are relatively rare in young adults, but they result in prolonged loss of function in these patients, thereby placing a huge burden on a country’s healthcare and economy. Femoral neck fractures in young adults are normally treated with head salvage surgery. However, primary head replacement surgeries have been gaining traction recently to expedite the recovery of these patients. In this study, we aimed to investigate the outcomes in young patients with femoral neck fractures and factors associated with their complications.Patients and methodsPatients with femoral neck fractures who underwent surgery in three tertiary hospitals [Hospital Tengku Ampuan Afzan (HTAA), Hospital Sultan Haji Ahmad Shah (HOSHAS), and Hospital Kuala Lipis] in Pahang state in Malaysia were reviewed and included in this study. The demographic profile of the patients, injury patterns, intervention details, functional outcomes, and complications were analyzed. The comparison between the sociodemographics, clinical assessment, and complication outcomes was analyzed using statistical software.ResultsThe complications were associated with the mechanism of injury, capsulotomy, and type of fixation. A total of 46 patients were included in the study. Most of the patients were found to have severe displacement based on Garden and Pauwels classification. The majority of the patients underwent femoral head salvage surgeries. Almost half of the patients sustained complications and were unable to achieve weight-bearing status at six months postoperatively.ConclusionDespite a relatively short follow-up period in our study, femoral neck fractures in young adults were found to be associated with a high rate of complications. Primary head replacement surgeries should be considered in high-risk patients with femoral neck fractures.

Results of fixed-angle device fixation (dynamic hip screw) in femoral neck fractures in young adults: a prospective study of 20 cases

Background: Femoral neck fractures constitute nearly half of the fractures of the hip. In young patients, hip preservation is advocated. Multiple cannulated screws and dynamic hip screws (DHS) are the preferred modalities. DHS gives better antirotational stability and fixation in femoral neck fractures. The purpose of this study was to assess functional outcomes after fixation of femoral neck fractures using DHS. Methods: A prospective case series study of 20 patients with femoral neck fracture were treated with DHS fixation. Exclusion criteria were patients with pathologic fractures, same-side shaft femoral fractures, skeletally immature patients, and those who were using walking aids before injury. Outcome was assessed by Harris Hip Score (HHS) and by radiographs at 3 and 6 mo. Results: The mean age at presentation was (38.5) years. Union was achieved in 19 patients (95%). The mean follow-up period was 7.13 months with a minimum of 6 mo for all patients included. There was a significant difference in nonunion rates if the tip-apex distance was more than 25 mm. Mean HHS at 6-month follow-up was 87.50 with a standard deviation±11.318. Conclusions: DHS results in better functional outcome with lower complication rates in transcervical and vertical shear femoral neck fractures in young adults. Level of Evidence: Level IV
