We compared the results of the surgical treatment of trochanteric hip fractures before and after surgeons had been introduced to the tip-apex distance (TAD) as a method of evaluating screw position. There were 198 fractures evaluated retrospectively and 118 after instruction. The TAD is the sum of the distance from the tip of the screw to the apex of the femoral head on anteroposterior and late...

OBJECTIVE To compare minimally invasive dynamic hip screw (MIDHS) fixation with conventional dynamic hip screw (CDHS) fixation for treatment of intertrochanteric femoral fracture. METHODS Of the 66 participants in this double-blind study, 35 were randomised to MIDHS and 31 to CDHS fixation. Main outcome measurements were wound size, haemoglobin decrease, blood transfusion rate, pain score, an...

OBJECTIVE To evaluate factors associated with revision of dynamic hip screw implant in patients undergoing the procedure for the fixation of intertrochanteric fractures. METHODS The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised records of patients who had undergone dynamic hip screw fixation surgery between 2008 and 2012. Medical records and dat...

PURPOSE To report results of twin hook fixation for proximal femoral fractures in comparison to those fixed with the conventional lag screw. METHODS Between August 2005 and July 2006, 2 men and 15 women aged 74 to 94 (mean, 85) years with proximal femoral fractures underwent open reduction and internal fixation using the twin hook system. The tip-apex distance was compared with that in 20 pat...

Background: The architecture of adult ulna is unique among long bones that have been described in the literature. But the best of our knowledge, the dorsal angulation of proximal ulna has not been described in detail. While using newer straight precontoured ulnar plates, the recognition of PUDA is important anatomic landmark for surgeons treating proximal ulna fractures, nonunions, malunions or...

The limitation of mechanical manufacturing will result in a small tilt angle the sample stage horizontal direction, which decreases spatial resolution imaging near-field scanning microwave microscopy (NSMM). In this paper, we focus on correction and improve NSMM image. results electromagnetic simulation line scan measurement demonstrate critical parameters affecting sensitivity NSMM, such as le...

PURPOSE To assess the one-year outcome of a dynamic hip screw (DHS) blade in the treatment of AO/OTA 31-A1 and 31-A2 intertrochanteric hip fractures. METHODS 35 men and 65 women aged 47 to 100 (mean, 83) years underwent fixation with a DHS blade for A1 (n=47) and A2 (n=53) intertrochanteric hip fractures after a low-energy injury. Patients were operated on within 48 hours of admission. Antero...

     Introduction: Objective: This study aimed to assess the possible variations in root canal anatomy and topography of the apices of first and second maxillary molars. Materials and methods: A total of 67 first and second maxillary permanent molars were collected. Access cavity was prepared and 2% methylene blue was injected. The teeth were demineralized by 5% nitric acid and cleared with met...
