[Joint-preserving treatment of medial femoral neck fractures with an angular stable implant].

Objective: Operative stabilization is recommended even for non-displaced or only slightly displaced femoral neck fractures. In addition to the known osteosynthetic procedures, an angular stabile implant system (Targon® FN) has been established since 2006 for treatment of such fractures.

Indications: Displaced femoral neck fractures (Garden III and IV) and non-displaced fractures (Garden I and II).

Contraindications: Fractures close to the hip joint, which are not classified as typical medial femoral neck fractures and patients with advanced osteoarthritis of the hip who would profit from an endoprosthetic procedure.

Surgical Technique: The operative procedure is shown after fracture reposition and central positioning of the guide wire as a standard course.

Postoperative Management: Early postoperative mobilization under guidance of a physiotherapist. Initially, partial weight bearing only in selected cases with severe displacement.

Results: In our patients collective the Targon® FN has been implanted in over 100 cases. Revision indications and secondary endoprosthesis were documented in only 9 % of the cases. This angular stable screw osteosynthesis system is a safe procedure to achieve patient mobility if the indications are adhered to and implantation is correctly carried out.
