About this study
Official title: Intracapsular Femoral Neck Fractures Fixation With a Dynamic Locking Plate and Screw System, Targon FN. Prospective and Retrospective Cohort Study.
The purpose of this study is to evaluate our experience in internal fixation of intracapsular femoral neck fractures with the Targon FN implant prospectively and retrospectively in terms of the outcomes and complications associated with the treatment.
Read the detailed description
Intracapsular femoral neck fractures include subcapital and transcervical fractures. They typically occur in a bimodal age distribution, with most occurring in the elderly population. The rest are the result of high energy injury in the young. Management of those fractures is based on few factors related to the patient, such as preinjury ambulatory status, age, cognitive function, and co morbidities, and on factors related to the fracture like the type of the fracture and the degree of displacement. Treatment options include nonsurgical management, fixation (percoutan, CRIF, ORIF) or arthroplasty (hemiarthroplasty, THR). Undisplaced hip fractures are defined as fractures where the inferior cortical buttress is undisplaced on the anteroposterior (AP) radiograph.[1] Undisplaced hip fractures includes fractures impacted in all degrees of valgus regardless of any angulations at the fractures' edges seen on the lateral radiographs. The fractures can be classified using either the Garden or Pauwel classifications for subcapital fracture or transcervical fractures, respectively. In displaced intracapsular femoral neck fractures like Garden type 3 and 4 or in unstable transcervcal fractures like Pauwel type 3 which are subjected to increased shear loads [2], the goals, for a physiologically young and active adult, are to preserve the femoral head, avoid osteonecrosis, and achieve union in order to avoid arthroplasty. Femoral neck fractures in young adults are associated with higher incidences of femoral head osteonecrosis [3-11] and nonunion [3, 4, 7, 12]. The reported rate of osteonecrosis after a femoral neck fracture in young patients ranges from 12% to 86% [3, 6-15]. This complication may lead to collapse of the femoral head and osteoarthritis. Salvage procedures, such as osteotomy, and other reoperations have high failure rates, and arthroplasty procedures are not ideal, given the patient's young age and higher level of activity. The achievement of an anatomic reduction and stable internal fixation is imperative. A review of the Cochrane database revealed 28 randomized or quasirandomized trials of 5,547 patients with femoral neck fractures treated with 19 different pin and/or screw constructs in a variety of configurations. [16] None of the implants had significantly superior results for outcomes related to fracture healing, osteonecrosis, wound infection, pain scores, reoperation rate, use of walking aids, periprosthetic fracture, or mortality.
Recently the Targon FN a new implant for fixation of femoral neck fracture has become available. The Targon FN implant consists of a small side plate with six locking screw ports. The two distal holes are used to fix the plate to the lateral cortex of the femur with angle stable 4.5 mm cortical screws. The proximal holes allow the implementation of up to four "TeleScrews" which cross the fracture site. These 6.5 mm screws are dynamic and allow therewith the collapse of the fracture at the femoral neck. The sliding during the collapse occurs within these screws so that a protrusion of the screws in the lateral soft tissue is prevented. The only report was reported by Martyn Parker MD and was released in Jatros Orthopädie 2008. He reported a serial of 50 femoral neck fractures, 27 (54%) of the fractures were undisplaced and 23 (48%) were displaced. There were two cases of fracture non-union; in one patient the plate became detached. One patient with a non-displaced femur neck fracture showed early radiographic signs of a possible avascular necrosis after one year. The implant was removed and the symptoms improved somewhat.
The purpose of this study is to evaluate our experience in internal fixation of intracapsular femoral neck fractures with the Targon FN implant prospectively and retrospectively in terms of the outcomes and complications associated with the treatment.

Questions about this trial
What is this clinical trial studying?
A study testing TARGON FN in people with Femoral Neck Fractures, run by Sheba Medical Center at 3 sites in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
overall survival, fixation survival and a composite end-point combining the two (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00830687, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2010.
