Cannulated hip screws

Bilateral femoral neck fractures are rare, and only a few cases have been reported following major trauma in children. An 8-year-old male patient presented with pain both hips and inability to bear weight on his lower limbs, four days after he fell through a roof while playing. The anteroposterior pelvic radiograph showed a displaced transcervical fracture of the right femoral neck and an undisplaced transcervical fracture of the left femoral neck. Operative fixation of both hips with cannulated cancellous screws done on the 5th day of injury led to a successful outcome...

Introduction: Currently, cannulated screws (CSs) and dynamic hip screws (DHSs) are widely used for the treatment of femoral neck fractures, but the postoperative complications associated with these internal fixations remain high. In response to this challenge, our team proposes a new approach involving triangular-supported fixation and the development of the proximal femoral bionic nail (PFBN). The primary objective of this study is to investigate the biomechanical differences among CSs, DHSs, and the PFBN in their capacity to stabilize femoral neck fractures...

The accuracy of screw placement is a key factor for the stability of the cannulated screws used in the fixation of femoral neck fractures. In this study we designed a navigation device for ensuring the screw reaches the ideal position for optimal fixation. From March 2019 to September 2020, 66 patients with femoral neck fracture were enrolled and divided into 2 groups, one group was treated using the traditional free-hand cannulated screw fixation and the other using the new navigation device with assisted fixation...

PURPOSE OF THE STUDY: Femoral neck fracture osteosynthesis is usually performed by using dynamic hip screw (DHS) or multiple parallel cannulated screws (MCS). In orthopedic surgery training, certain hip fractures are one of the most common operations performed by residents. It has been questioned, whether residents can provide as safe treatment and patient outcomes as those of more experienced surgeons. The aim of this study was to evaluate the effect of surgical experience on risk of complications by comparing the surgical performance and clinical outcomes in femoral neck osteosyntheses between surgical residents and orthopaedic surgeons...

Introduction Hip fractures include intra- and extracapsular fractures with hip hemiarthroplasty, intramedullary (IM nailing), dynamic hip screw (DHS) fixation and cannulated cancellous screws being the main treatment options. The Nottingham Hip Fracture Score (NHFS) is used to predict the risk of 30-day mortality with some studies investigating its use for one-year mortality. This study aims to investigate the impact of polypharmacy on post-operative hip fracture mortality and the correlation with NHFS predicted mortality...

INTRODUCTION: Traumatic hip dislocation with ipsilateral femoral neck fracture, intertrochanteric fracture and acetabular fracture is a rare and serious injury that occurs mostly in young patients and after high-energy trauma. The treatment of these injuries is a major challenge for orthopedic surgeons; it can have devastating consequences if not treated properly, including avascular necrosis of the femoral head and traumatic osteoarthritis of the hip. In previous case reports only internal fixation of femoral neck fracture was performed without revascularisation and there was a lack of long-term follow-up results...

BACKGROUND: The aim of this study is to evaluate comparative biomechanical fixation provided with the BDSF method with the conventional CC screw fixation for treatment of femoral neck fractures with three parallel cannulated screws. METHODS: This is a prospective cohort study. There were two teams of surgeons out of which one team operated the patients with BDSF technique and second with conventional CC screw fixation technique; thus, the patients were randomly distributed into two groups...

MATERIALS AND METHODS: Retrospective and comparative study of 53 patients with femoral neck fracture, operated between 2015 and 2022 with fixation with three cannulated screws, 22 with a triangle configuration (triangle group) and 31 in an inverted triangle (inverted triangle group)...

BACKGROUND: Femoral neck fractures are a common cause of morbidity and mortality in the community. Minimally displaced subcapital necks of femoral fractures are usually managed with internal fixation, although there is debate as to which method is superior. This systematic review aimed to compare the outcomes of different fixation methods in the management of this common fracture. METHODS: This systematic review was conducted in accordance with PRISMA statement guidelines...

OBJECTIVE: To compare the clinical results of a new femoral neck system (FNS) and cannulated compression screws (CCS) for the treatment of femoral neck fractures in younger patients. METHODS: Retrospective study was performed in younger patients with femoral neck fractures that were treated with FNS or CCS from August 2017 to August 2022. The hip functional outcomes were assessed with the Harris hip score (HHS). Secondary outcomes included the surgical time, surgical blood loss, satisfaction visual analog scale (VAS), fluoroscopy frequency, fracture healing time and complications...

Stable slipped capital femoral epiphysis (SCFE) is a pediatric hip disorder managed with in situ fixation of the proximal femoral epiphysis, otherwise known as 'pinning the hip'. The objective of this study was to characterize how the choice of implant for in situ fixation of stable SCFE has changed over time. A systematic review of publications concerning in situ fixation of stable SCFE from January 1993 to November 2021 was conducted. The change in the type, diameter, and number of implants used in publications over time and the age of their respective patient cohorts was evaluated...

BACKGROUND: This study aimed to access the radiologic and clinical outcomes after arthroscopic reduction and internal fixation with screws in patients with posterior wall fractures of the acetabulum. METHODS: From May 2013 to December 2019, 13 patients (11 men and 2 women) with posterior wall fractures of the acetabulum were treated with arthroscopic reduction and internal fixation with screws at two medical centers. The mean age at the index operation was 39 years (range, 22-58 years)...

PURPOSE: Several surgical implants have been used for the treatment of neck of femur fracture (NOF) in younger patients such as dynamic hip screw (DHS) and cannulated compression screw. However, the superiority of one or another osteosynthesis device remains a matter of debate. The aim of this work is to evaluate and compare three fixation modalities: Cannulated Hip Screws (CHS), DHS and DHS associated to anti-rotating screw for surgical treatment of femoral neck fracture in young adults...

The aim of the present study was to investigate the clinical efficacy of three cannulated screws with parallel distribution in comparison with the 'gold standard' of inverting three cannulated screws with triangular distribution, in the treatment of femoral neck fractures in the elderly. A total of 106 elderly patients with femoral neck fractures treated at the Department of Orthopedics of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial Hospital) from October 2018 to March 2020 were retrospectively analyzed and divided into groups A and B...

BACKGROUND: The femoral neck system (FNS) is commonly used for internal fixation of femoral neck fractures and has shown promising results. However, we have observed cases of peri-implant subtrochanteric femur fractures associated with the use of FNS at our institution. This case series aims to investigate four cases of peri-implant subtrochanteric fractures in patients treated with the FNS implant for femoral neck fractures. CASE PRESENTATION: We reviewed 35 patients who underwent treatment with FNS for femoral neck fractures between January 2017 and December 2021 at our level 1 trauma institution...

INTRODUCTION: Pauwels Type III fractures are unstable and frequently treated with cannulated screws (CS) or dynamic hip screws (DHS). The newly developed talon-cannulated compression devices (TCCD) have the potential to provide rotational stability, mainly through their talon. The study investigates whether TCCD has mechanical advantages over conventional screws or can be as stable as DHS in a reverse triangle configuration for an unstable femoral neck fracture. MATERIAL AND METHODS: After creating a standard Pauwels Type III unstable femoral neck fracture in 36 synthetic femur bones in cortical/hard cancellous bone density, 18 were reserved for dynamic-static tests, and 18 were used for torsional tests...

AIMS: The importance of hip fracture care has resulted in an abundance of hip fracture management literature. The degree this evidence is incorporated into clinical practice is unknown. We examined 5 trends in hip fracture management: arthroplasty versus fixation, total hip arthroplasty (THA) versus hemiarthroplasty (HA), cemented versus uncemented femoral stem fixation, short versus long cephalomedullary nail (CMN) fixation, and time from admission to surgery. Our primary aim was to understand and assess hip fracture management trends in relation to pertinent literature...

BACKGROUND: Conventional cannulated screws are commonly used for internal fixation in the treatment of vertical femoral neck fractures. However, the noticeably high rates of undesirable outcomes such as nonunion, malunion, avascular necrosis, and fixation failure still troubled the patients and surgeons. It is urgent to develop new cannulated screws to improve the above clinical problems. The purpose of this study was to design a novel magnesium-titanium hybrid cannulated screw and to further evaluate its biomechanical performance for the treatment of vertical femoral neck fractures...
