A new species of bathyergid mole-rat, Fukomys vandewoestijneae, is described from an area on the Zaïre-Zambezi watershed, centred on the Ikelenge pedicle in the North-Western province of Zambia. It is diagnosed by a unique combination of morphological (size, lack of clear headmarks), chromosomal (2n= 44) and DNA sequence characteristics. This medium-sized species belongs to the Giant mole-rat "...

INTRODUCTION We present the method of pedicle labial urethroplasty for urethral reconstruction in female patients treated for urethral strictures. PATIENTS AND METHODS We performed urethral reconstruction using a pedicle labial flap in 2 female patients (23 and 70 years old) for urethral stricture (posttraumatic and postinflammatory origin). We used as a patch a pedicle skin flap obtained fro...

BACKGROUND Computerized navigation improves the accuracy of minimally invasive pedicle screw placement during spine surgery. Such navigation, however, exposes both the patient and the staff to radiation during surgery. To avoid intraoperative exposure to radiation, tracked ultrasound snapshots-ultrasound image frames coupled with corresponding spatial positions-could be used to map preoperative...

the coverage of soft- tissue defects of the hand specially volar side needs special consideration. although certain local flaps have been described and used for resurfacing the palm, extensive injury requires distant or free flaps for coverage. abdominal pedicle flap has been traditionally used for extensive hand injuries, however there is no doubt that one of the ideal tissues for resurfacing ...

INTRODUCTION Pedicle screw fixation in a severely osteoporotic spine remains a challenge for orthopaedic surgeons. Previous studies have demonstrated that pedicle screw fixation is highly correlated to the bone mineral density [1], and increasing the screw’s pullout strength can be achieved using a variety of methods, these include the use of pedicle screws with various designs [2,3]. However, ...

STUDY DESIGN Case-control study. PURPOSE To evaluate clinical and radiological results of transforaminal lumbar interbody fusion (TLIF) performed with cortical bone trajectory (CBT) pedicle screw insertion with those of TLIF using 'conventional' or percutaneous pedicle screw insertion. OVERVIEW OF LITERATURE CBT is a new trajectory for pedicle screw insertion in the lumbar spine; clinical a...

Spine stabilization after C3-C7 laminectomy can be accomplished with many instrumentation options. A hybrid construct using lateral mass screws from C3 to C5 and pedicle screws at C7 can potentially maximize strength and solve the spatial constraints introduced by the placement of C6 lateral mass screws and C7 pedicle screws. Seven cadaveric cervical spines from C2 to T2 were potted in a custom...

BACKGROUND Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. However, the misplacement of pedicle screws can lead to disastrous complications. Inaccurate pedicle screw placement is relatively common even when placement is performed under fluoroscopic control. In order to improve the accuracy of the screw placement, we applied a technique using g...
