Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A post-market, prospective study to evaluate the reoperation rate of displaced and nondisplaced femoral neck fractures treated with the Femoral Neck System (FNS)™

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To evaluate the re-operation rate for any reason of displaced and non-displaced femoral neck fractures treated with the Femoral Neck System (FNS)™ at one year post-operation. The Femoral Neck System (FNS)™ represents a new generation of implants designed to improve outcomes in the treatment of femoral neck fractures. These implants offer a fixed angle construct and all of its mechanical advantages with regards to neutralizing shear and providing stability while not exerting a rotational malreduction force on the fracture. The FNS system has been shown to compare favorably to traditional fixed angle constructs in a cadaveric model

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* The subject must provide written informed consent
* The subject must be eighteen (18) years of age or older.
* The subject must be willing and able to make all required study visits including one (1) year post-operative follow-up.
* The subject must be able to follow instructions.
* Subject has experienced displaced or non-displaced intracapsular femoral neck fracture

Exclusion Criteria

* Subject with fracture occurring more than 7 days prior to the date of surgery
* Subject has more than one fracture on target extremity.
* Subject is obese as defined by a Body Mass Index (BMI) \> 45 at the time of surgery.
* Subject, in the opinion of the Investigator, has an emotional or neurological condition that preludes cooperation and compliance with the rehabilitation regimen.
* Therapy with another investigational agent within thirty (30) days of Screening or planned therapy with another investigational agent during the course of the study.
* Subject has a physical condition that, in the opinion of the Investigator, would preclude adequate implant support or impede healing (e.g. blood supply impairment insufficient bone quality or quantity, or an active, local or systemic infection). If this is identified at the time of surgery, the subject will be screen failed.
* Subject has undergone previous surgery on the target hip.
* Current systemic therapy with cytotoxic drugs.
* Subjects with a history of poor compliance with medical treatment.
* Subjects with a medical or physical condition that, in the opinion of the Investigator, would preclude safe subject participation in the study.
