This study compared the biomechanics of 3 fixation techniques: bilateral pedicle screw (BPS) fixation, unilateral pedicle screw (UPS) fixation, and UPS supplemented with translaminar facet screw (UPS+TLFS) fixation. The study was conducted in an L3-L5 finite element model. Three different finite element models were created by adopting different fixation techniques after removal of the left L3-L...

BACKGROUND The use of perforator flaps has allowed for the transfer of large amounts of soft tissue with decreased morbidity. For breast reconstruction, the deep inferior epigastric perforator flap, the superior and inferior gluteal artery perforator flaps, and the transverse upper gracilis flap are all options. The authors present an alternative source using posterior thigh soft tissue based o...

BACKGROUND Surgeons often advise patients with large ptotic breasts to undergo a Wise pattern reduction (WPR) mammaplasty using an inferior pedicle technique with consideration of a free-nipple graft. OBJECTIVE We describe the Boston modification of the Robertson technique (BMRT), which allows for the elimination of the vertical scar using a low horizontal scar mammaplasty with a broad centra...

Aim: The advent of 3D photoimaging and mammometrics has allowed for quantitative, volumetric breast analyses. This study uses 3D photoimaging and mammometrics to compare the postoperative morphometric outcomes of the modified Robertson technique to the more traditional Wise pattern inferior pedicle technique. Methods: Inferior pedicle reduction mammoplasty was performed using either a Wise patt...

The deep inferior epigastric artery perforator flap is an option for women desiring autologous tissue breast reconstruction. If this reconstruction fails, other autologous tissue flaps, including the gluteal artery perforator and latissimus dorsi flaps, may be used for salvage. The anterolateral thigh (ALT) flap offers adequate tissue volume for breast reconstruction, acceptable fat quality and...

Study Design Adult human osteologic specimens were assessed for spondylolytic defects and characterized. Objectives To characterize and determine the prevalence of spondylolytic defects in an osteological collection. Methods Lumbar vertebrae from the Hamann-Todd Osteological Collection at the Cleveland Museum of Natural History were examined. Digital images of specimens with L5 isthmic spondylo...

Background: Macromastia or breast hypertrophy is a common problem in the general female population, leading to debilitating symptoms and poor quality of life. Breast reduction surgery relieves disabling with great satisfaction, even though postoperative complications regularly occur.

PURPOSE Many studies have been conducted to date regarding whether the right hepatic vein is the accurate border that divides the anterior and posterior section of the right liver. It has been reported that the Glisson pedicle of the right liver may be an anatomical variation that does not have a consistent morphology. We analyzed the relationship between the true borders of the anterior and po...

PURPOSE Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is increasingly popular for the surgical treatment of degenerative lumbar disc diseases. The constructs intended for segmental stability are varied in MI-TLIF. We adopted finite element (FE) analysis to compare the stability after different construct fixations using interbody cage with posterior pedicle screw-rod or ped...
