A subcutaneous pedicle ulnar flap used to cover a skin defect around the wrist is reported. Unlike the standard ulnar flap, which is isolated around the dorsal branch of the ulnar artery and its associated veins, this flap is based on the ascending branch of the dorsal branch of the ulnar artery more proximally to obtain a longer vascular pedicle. A subcutaneous pedicle flap that contained the ...

OBJECTIVE To evaluate the feasibility, safety and accuracy of pedicle screw placement in the upper thoracic spine using the free-hand technique with the aid of fluoroscopy; to analyze the methods used to verify correct screw positioning intra and postoperatively. METHOD All patients with instability of the cervicothoracic or upper thoracic spine and at least one screw placed in the segment T1...

STUDY DESIGN A retrospective analysis of 1078 spinal surgical procedures with lumbar pedicle screw placement at a single institution. OBJECTIVE Based on previously established normative values, triggered electromyographic stimulation (TrgEMG) was re-examined to evaluate its efficacy in determining screw malposition. SUMMARY OF BACKGROUND DATA Threshold values for confirmation of intraosseou...

Posterolateral fusion has long been considered the "gold standard" technique for surgical treatment of adult spondylolisthesis. Superior results have subsequently been reported with interbody fusion with cages and posterior instrumentation. The goal of this prospective study was to compare the two techniques regarding their clinical outcomes and fusion rates. Fifty-two patients with isthmic spo...

There is a thin bony pedicle joining the lenticular plate to the rest of the long process of the incus. We have previously presented a brief review of its anatomy; new histological observations in cat; and a simplified finite-element model of the long process, pedicle, lenticular plate, incudostapedial joint and stapes head in the cat. Low-frequency simulations suggested that there may be more ...

Sound knowledge of various features of morphology of pedicles is required for accurate pedicle screw placement. Previous studies suggest variation in morphology of pedicles in different population groups. This prospective study was done to assess the morphological features of the pedicles in north Indian population using computerized tomography scans and Orthopaedic digital imaging software. Th...

This article reviews the historical context, indications, techniques, and complications of four posterior fixation techniques to stabilize the subaxial cervical spine. Specifically, posterior wiring, laminar screw fixation, lateral mass fixation, and pedicle screw fixation are among the common methods of operative fixation of the subaxial cervical spine. While wiring and laminar screw fixation ...

BACKGROUND Gigantomastia is a rare condition characterized by excessive breast growth and can be physically and psychosocially disabling for the patient. Regarding management of gigantomastia, this study evaluates the outcomes of superomedial pedicle with vertical scar or wise pattern skin excision. METHODS A total of 425 patients who underwent reduction mammoplasty in our institution ...

There has been no report of bilateral pedicle stress fractures involving two vertebrae. The authors describe a unique case of spondylolisthesis accompanying a bilateral pedicle stress fracture involving two vertebrae. De novo development of spondylolisthesis at the L5-S1 vertebrae accompanying a bilateral pedicle stress fracture at L4 and L5 was observed in a 70-year-old woman. The patient's me...
