Objective: To design and manufacture a new type instrument and its matching tools for the proximal femur.
Methods: A new type instrument of subtrochanterical fracture-static 3-dimensional screw-plate system(STDSP)was designed and manufactured. The different types of accessory instruments which adapted to STDSP,the aiming guide, and the accessory tools were also designed and manufactured, and they were tested on bones.
Results: STDSP included 3 special lag screws and 1 anatomic plate. The lag screws distributed in femoral neck like "or"shape. There was 135 degree between the lag screws and femoral shaft. The shape of the plate was similar to the anatomic structure of the proximal thighbone. The posterior screw was stably connected to the plate. The plate was affixed crosswise to the lateral and anterior side by bicortical screws. The aiming guides and all kinds of accessory tools could help to install STDSP exactly and conveniently,which was verified on cadavers and X-ray photographs.
Conclusion: STDSP has the function of dynamic compressing in 3-dimensional space, and can match with the structure of the proximal femur preferably. STDSP may be a suitable instrument to the subtrochanteric fractures. The accessory apparatus of STDSP has simple configuration,and can let the STDSP be installed accurately, conveniently and rapidly.

Subtrochanteric fractures in older patients are typically due to low-energy falls. The standard of care is intramedullary nailing. The Smith & Nephew Trigen Intertan (Memphis, TN, US) is an intramedullary nail with a novel design that incorporates two integrated compression screws.

Objective: Despite several surgical options, there has yet to be a consensus on the best treatment for femoral neck fracture (FNF) due to higher complication rates compared to other bone fractures. This study aims to examine the possible consequences and solution suggestions of changing screws during surgery for various reasons in FNF surgical treatment from a biomechanical perspective.
Method: FNF and treatment materials were analyzed biomechanically using a package program based on the finite element method (FEM).

Background: This study aimed to analyze the files of patients treated using PFN-A or INTERTAN intramedullary nails to reveal additional superiorities or disadvantageous factors for selecting the better intramedullary fixation method in patients presenting with intertrochanteric femur fractures.
Methods: In this retrospective study, the files of the patients who were operated on for intertrochanteric femur fractures using intramedullary fixation methods between September 2010 and June 2015 in the Orthopedics and Traumatology Clinic, Çukurova University Faculty of Medicine, were reviewed. The data including age, gender, chronic diseases, causes of fractures, fracture classification based on Arbeitsgemeinschaft für Osteosynthesefragen (AO), the nail type (long or short), the interval between trauma and surgery, duration of anesthesia and surgery, hospitalization duration, amount of blood transfusion, the Tip-Apex Distance (TAD) in postoperative radiographs, functional outcomes according to Harris Hip Score (HHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), postoperative complications, need for revision, and mortality was noted.

Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.
