Background: Intramedullary nailing is the treatment of choice for atypical femoral fractures. However, several problems, such as iatrogenic fracture and medial gap opening, can occur during intramedullary when fractures are associated with excessive anterolateral bowing. To overcome these we have developed a new grading system bowing technique nailing. The core this matching anterior curvature nail femur passes apex curvature, by rotating externally. Methods: From January 2005 through March...

Background: The purpose of the present study was to investigate effectiveness using computed tomography (CT) capsular sign with lipohemarthrosis hip joint as a selective indicator for preoperative magnetic resonance imaging (MRI) or prophylactic fixation ipsilateral femoral neck prevention unplanned surgery due delayed diagnosis occult fractures in patients high-energy shaft fractures. Methods: We evaluated CT fracture without an fracture. considered positive when side-to-side difference...

To elucidate the effect of anterolateral bowing on fracture height atypical femoral fractures (AFFs), we separated AFFs into 2 groups according to presence (straight group and group) analyzed height. The aims this study were evaluate clinical radiological features in straight group, determine which factors associated with total cohort each subgroup.Ninety-nine patients included (43 56 group). Clinical characteristics compared between groups. Multivariable linear regression analysis was...

Paget's disease of bone leads to change in the shape and size results reduced strength, leading complications deformity, arthritis, fracture. Due unknown reasons, is rare Asian descendants. We report cases who visited our institute for 15 years reviewed literatures.We retrospectively medical records radiograms 8 patients (6 female 2 male) were diagnosed as bone. Diagnosis was confirmed by typical radiological feature involved skeletons and/or pathologic findings.Pelvis, skull spine three...

Exchange nailing is a standard treatment for femoral shaft nonunion after intramedullary nailing. However, substantial uncertainty and controversy remain regarding the mode of interlocking fixation. This study aimed to compare success rate time union exchange based on modes.We retrospectively analyzed all consecutive patients who underwent aseptic between February 2000 2021. Patients using dynamically locked statically constituted dynamic group static group, respectively. We compared rates...

Autosomal dominant type II (AD II) osteopetrosis is a rare inheritable metabolic bone disease characterized by hard but brittle and narrow medullary canal. Intramedullary nailing (IMN) difficult attractive option for the treatment of subtrochanteric fractures in patients with AD osteopetrosis.Two sustained after fall.IMN was performed through sequential use instruments such as 4.9-mm drill bit, small reamer, larger reamer over-reaming.In first case, IMN left some gap at fracture site....

Amputation of diabetic foot ulcer and infection is a critical modality for saving patient's life from threatening infections or ischemic limbs. However, it can cause serious handicaps complications, such as lifetime shortening re-amputation the other limb. The minimal amputation main goal in patients. insufficient have harmful effect on decision very difficult should be made using multidisciplinary approaches. All aspects situation, including vascular status, degree infection, medical...

This paper mainly examines the fixation performances of cephalomedullary nail for incidence intertrochanteric (IT) fracture to guide appropriate fixations with respect bone density in terms a biomechanical perspective. It is substantially important which types are applied during operation since it tends induce backout or migration helical blade and screw according weight density. Biomedical polyurethane (PUR) foam blocks simulating human adopted two grades densities simulate normal person an...

Treatment of comminuted patellar fractures accompanied by coronal split articular and inferior pole fragments is a challenge. To treat this difficult fracture, we perform fragment detachment separate fixation for fragments. We aimed to evaluate the radiological clinical outcomes our technique in at least 1 year after surgery.

To analyze the reason of aging deterioration in transmission line insulators, we performed a various kind test and investigated mechanical electrical characteristics insulators. Test samples consisted K-1989(36,000lbs), K-1995(36,000lbs) K-2001(36,000lbs) type insulators which have been used domestic 154 kV lines. As result this test, facts turned out K-2001 insulator contain 17 wt.% alumina has better physical than K-1989 8 wt% alumina. Relativity density fracture toughness porcelain are...

Purpose: The purpose of this study is to investigate the outcome open reduction and internal fixation with a headless screw auto iliac bone graft for patients scaphoid nonunion advanced collapse (SNAC) stage II III. Materials Methods: A retrospective analysis was conducted 10 diagnosed or III SNAC, consequently treated without radial styloidectomy between 2010 2013. Radiographic results were evaluated by union, scapholunate angle lateral intrascaphoid angle. Clinical range motion, pain, grip...

Oncogenic osteomalacia is a rare paraneoplastic syndrome, characterized by hypophosphatemia, renal phosphate wasting, osteomalacia, and multiple insufficiency fractures, as result of the tumor.A wide excision causative tumor considered treatment choice, following which, dramatic recovery expected.Authors report case in which symptoms bone mineral density were dramatically recovered after an around tibialis posterior muscle oncogenic osteomalacia.
