OBJECTIVES: Traumatic spinopelvic dissociation separates the spinal column from the pelvis, which usually creates lumbosacral kyphosis. We aimed to examine how the spinopelvic profiles changes after traumatic spinopelvic dissociation, and which are the relevant factors for the sagittal imbalance of the spine. DESIGN: Retrospective analysis. SETTING: Level I trauma center PATIENTS:: Thirty-nine consecutive patients who were diagnosed with traumatic spinopelvic dissociation and had a minimum 2-year radiological follow-up were included...

INTRODUCTION: Evidence regarding whether the polyaxial pedicle screws at the upper instrumented vertebrae (UIV) are superior to monoaxial pedicle screws in prevention of proximal junctional kyphosis (PJK) is less clear. The aim of this study was therefore to explore the influence of different type of pedicle screws at UIV on the incidence of PJK. METHODS: 242 patients surgically treated with instrumented segmental posterior spinal fusion at a minimum 4 motion segments were reviewed retrospectively...

BACKGROUND: The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated PEF of untreated chlamydia. METHODS: We used two large retrospective population-based cohorts of women of reproductive age from settings with widespread chlamydia control to calculate the PEF of treated chlamydia on PID at 12-months...

BACKGROUND AND OBJECTIVES: Treatment of pelvic tumors remains challenging due to complex anatomy, poor oncological outcome and high complication rates. We sought to investigate the long-term oncological and surgical outcome of these patients. METHODS: Between 1980 and 2012, 147 patients underwent surgical treatment for pelvic sarcoma. Histological diagnosis was Chondrosarcoma in 54, Ewing's Sarcoma/PNET in 37, Osterosarcoma in 32 and others in 24 patients. Statistical analysis for the evaluation of oncological and surgical outcome was performed by applying Cox proportional hazards regression and Fine-Gray regression models for competing risk (CR) endpoints...

OBJECTIVE: To determine the incidence of antenatal renal pelvic dilatation to evaluate antenatal resolution/ progression and post-natal outcome. METHODS: This retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of all women found with renal pelvic dilatation in antenatal scans between January 2011 and December 2013. A cut-off of 5mm was used to diagnose renal pelvic dilatation. Renal pelvic dilatation was categorised into three groups: mild (5-6mm in second trimester and 5-9mm in third trimester), moderate (7-10mm in second trimester and 10-15 in third) and severe (more than 10mm in second trimester and more than 15mm in third trimester)...

BACKGROUND: The administration of blood transfusion (BT) has been associated with a decrease in survival expectancies in patients treated with radical cystectomy (RC), as a consequence of the immunosuppressive effect mediated by BT. We sought therefore to evaluate if the usage of BT may influence the risk and pattern location of distant recurrences after RC, which may be influenced by this effect. METHODS: Data from 2 independent cohorts of consecutive patients with bladder cancer treated with RC were analyzed...

BACKGROUND: Changes in spinal alignment and pelvic tilt alter acetabular orientation in predictable ways, which may have implications on stability of total hip arthroplasty (THA). Patients with sagittal spinal deformity represent a subset of patients who may be at particularly high risk of THA instability because of postural compensation for abnormal spinal alignment. METHODS: Using standing stereoradiography, we evaluated the spinopelvic parameters, acetabular cup anteversion, and inclination of 139 THAs in 107 patients with sagittal spinal deformity...
