BACKGROUND: The treatment of proximal femoral fractures in geriatric osteoporotic patients continues to be a challenge in orthopaedic trauma. Various kinds of cephalomedullary nails, such as gamma nail, InterTan and PFNA were used clinically. The latest generation PFNA II, specially designed for Asian population, is commonly used for geriatric per-/intertrochanteric fractures. The aim of this study was to determine whether the current PFNA-II proximal segment length is suitable for the greater trochanter height, as assessed by postoperative radiograph measurements...

OBJECTIVE: We assessed factors associated with cut-out after internal fixation of proximal femoral fractures using double lag screw nails. DESIGN: Retrospective cohort study. SETTING: A university hospital. PATIENTS AND METHODS: Patients with non-pathological intertrochanteric femur fractures and a minumum 90days follow-up who underwent internal fixation with dual lag screw nails were included. Potential risk factors for lag screw cut-out investigated by our study were: age, gender, body mass index, comorbidities (American Society of Anesthesiologists [ASA] classification), type of fracture (AO/OTA classification), fracture stability, side, operation time, implant length, reduction quality, tip-apex distance (TAD), and lag screw configuration...

Osteopetrosis is a rare, inherited disease characterized by defects in osteoclastic function that results in defective bone resorption. When fractures are encountered, fixation is extremely difficult. Osteopetrosis patients have an increased predisposition to infection. If infection develops after a fracture, treatment is more difficult. In this paper, treatment is presented of a 49-year old female to whom proximal femoral nailing was applied for fixation of an osteopetrotic proximal femur fracture; and when it was unsuccessful, revision was made with a locked anatomic plate, which subsequently led to development of infection...

BACKGROUND: Femoral neck fractures are the most common fractures among the elderly. The two operative approaches used for the treatment of AO/OTA 31 intertrochanteric fractures include an intramedullary device (proximal femoral nail [PFN]) or an extramedullary device (sliding/dynamic hip screw [DHS]). The aim of this study was to provide objective evidence of local soft tissue injury by measuring serum creatine phosphokinase (CPK), a biochemical marker, to quantify muscle damage and inflammation in patients treated by the two approaches...

Unstable intertrochanteric fractures are commonly treated with a cephalomedullary nail due to high failure rates with a sliding hip screw. The Omega3 Trochanteric Stabilizing Plate is a relatively new device that functions like a modified sliding hip screw with a proximal extension; however, its mechanical properties have not been evaluated. This study biomechanically compared a cephalomedullary nail, that is, Gamma3 Nail against the Omega3 plate. Unstable intertrochanteric fractures were created in 24 artificial femurs...

Atypical femoral fractures have been associated with long term use of bisphosphonates. Our study plan was to report the outcome of treatment for a series of -patients with an atypical femoral fracture and to compare the characteristics of those patients with a proximal femoral fracture. 21 atypical fractures were identified over a seven year period and these were compared with those of 2.547 hip fracture patients treated over the same time period at a single centre. The mean age of patients with an atypical fracture was on average nine years less than that for the hip fracture patients (72 as against 81 years, p = 0...

INTRODUCTION Intramedullary nailing is a common treatment for proximal femoral fractures. Fracture of the nail is a rare but devastating complication that exposes often frail patients to complex revision surgery. We investigated which risk factors predict nail failure. METHODS We reviewed all cases of nail breakage seen over a 10-year period in a single busy trauma unit; 22 nail fractures were seen in 19 patients. Comparison was made with a group of 209 consecutive patients who underwent intramedullary fixation of a proximal femur fracture with no nail breakage over a 2-year period...

PURPOSE: In femoral trochanteric fractures, fractures whose fracture lines extend to the basal neck or to the subtrochanteric part have high instability. Area classification can identify such instable fractures. The best choices of internal fixators for femoral trochanteric fractures were investigated according to area classification. METHODS: Femoral trochanteric fractures were investigated with respect to area classification. In area classification, the proximal femur is divided into 4 areas with 3 boundary lines: Line-1 is the center of the neck; Line-2 is the border between the neck and the trochanteric zone; and Line-3 links the inferior borders of the greater and lesser trochanters...

Introduction/Background: With extended life expectancy, the number of primary joint arthroplasties has also increased. Revision surgery is also more often necessary, due to aseptic or septic loosening of the prosthesis or periprosthetic fracture. Large bone defects often occur in these patients and several non-modular, conventional implants are available to handle this difficult situation. Custom made implants offer an individually designed and defect-adapted shape with perfect covering of the lesion, but may delay the operation...

We present the case of a 39-year-old sportswoman who was involved in a motorcycle accident in 2012. She sustained a complex proximal femoral fracture that involved the neck and trochanteric region. We decided to preserve the natural bone stock and repair the fractures, adopting skeletal traction in the first stage and then implanting an intramedullary nail. Twenty months later the fracture was healed clinically and radiologically and the patient was able to walk and run without pain.

Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the fracture with a proximal femoral nail (Zimmer® Natural Nail™ System). One day after the procedure, the patient complained of pain and swelling on the anteromedial side of his middle thigh followed by hypotension, anemia and prolonged thigh swelling...
