#1
Ross C Puffer, Marcus J Gates, William Copeland, William E Krauss, Jeremy Fogelson
BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...

BACKGROUND: Early identification of patients with pelvic fractures at risk of severe bleeding requiring intervention is critical. We performed a multi-institutional study to test our hypothesis that pelvic fracture patterns predict the need for a pelvic hemorrhage control intervention. METHODS: This prospective, observational, multicenter study enrolled patients with pelvic fracture due to blunt trauma. Inclusion criteria included shock on admission (systolic blood pressure <90 mm Hg or heart rate >120 beats/min and base deficit >5, and the ability to review pelvic imaging)...

Through this single-center consecutive prospective study, we evaluated the results of a combined approach for L5-S1 isthmic spondylolisthesis, using a polyetheretherketone (PEEK) interbody lordotic cage during anterior approach and pedicle screw-based posterior fixation. Between 2010 and 2014, 27 adult patients were treated for L5-S1 isthmic spondylolisthesis (high and low grades) by a combined approach with a minimum follow-up of one year. Clinical outcome was assessed before surgical treatment and at four months and one year after surgery by: VAS, Oswestry Index (ODI) and Rolland-Morris scores...

BACKGROUND: The use of a trabecular metal revision shell with metal augmentation to fill segmental or irregular defects during complex revision hip arthroplasty has been shown to provide good short-term results in prior published series. Longer-term results of the several cup-augment constructs used clinically are not known. The objective of this study was to report, with minimum 5-year radiographic and clinical follow-up, the outcome of these various constructs in revision total hip arthroplasty...

BACKGROUND: Limb length discrepancy is one of the most common complications after hip arthroplasty. We developed a device - intraoperative limb-length measurement and osteotomy device (ILMOD), and applied it to patients who were treated with hemiarthroplasty for femoral neck fracture to improve limb length discrepancy by providing an accurate osteotomy during hemi-arthroplasty. METHODS: Between April 2012 and October 2013, 65 patients were treated with hip hemiarthroplasty for femoral neck fracture at our trauma center...

PURPOSE: Pelvic vascular injury is a serious complication associated with acetabular component setting with screw fixation in cementless total hip arthroplasty (THA). In this study, we investigated the safety zone for acetabular component setting with screw fixation in cementless THA as a means to prevent pelvic vascular injury. METHODS: Thirty left hip joints of Japanese cadavers (11 males and 19 females) were analyzed. We used a hemispherical measuring cup with 52 guide holes designed to allow vertical insertion of a Kirschner wire...

A 7-year-old cat was referred with pelvic limb ataxia. Radiography and CT revealed bone resorption of the L1 vertebral arch, and myelography identified a compressive extradural lesion. The mass was surgically removed and histopathologically diagnosed as giant cell osteosarcoma. Three years later, the recurrent tumor resection and vertebral fixation were performed. Six months later, vertebrectomy was performed to radically excise the recurrent mass and a titanium spinal cage was placed. The cat is alive approximately 5 years after the first surgery...

INTRODUCTION: Laparoscopic sacrocolpopexy (LSC) has established itself as a safe method for the management of pelvic organ prolapse (POP). Laparoscopic suturing is a time-consuming intraoperative task during LSC. Self-retaining barbed sutures (SBSs) are known to reduce the operative time in laparoscopic cases. The current study aimed to evaluate the efficacy and safety of SBS during the performance of LSC. MATERIALS AND METHODS: Twenty female patients with symptomatic POP were treated with LSC by an expert surgeon...

The mechanical outcomes of patients with pelvic bone tumors involving zone I or zone I + IV who received resection and different reconstructions are not clear. Therefore, the purpose of this study was to compare the outcomes of different rod-screw systems in reconstruction for these patients, and evaluate the relative risk of mechanical failure for them. We reviewed 30 patients for a mean duration of 40.4 months of follow-up (range, 13.1-162.2 months), five patients had mechanical complications. The mechanical survival rate of two-rod and four-screw (TRFS) group was significantly higher than one-rod and two-screw (ORTS) group (p = 0...

BACKGROUND: Fixation strength of constructs placed across the pubic symphysis after injury is dependent on screw length, maximisation of which requires knowledge of the bony anatomy. The aim of this study was to describe the ideal angle of drilling to achieve maximal safe screw placement within the pubic body. Furthermore, the influences of age and gender on the skeletal topography were investigated. METHODS: Three hundred CT scans of patients without pelvic injury were analysed to record the angle of the pubic body (APB) with respect to the coronal plane, and the depth of the pubic body (DPB) in the sagittal plane...

Midurethral slings are used to correct urethral hypermobility in female stress urinary incontinence, defined as the complaint of involuntary urine leakage when the intra-abdominal pressure is increased. Structural and thermal features influence their mechanical properties, which may explain postoperative complications, e.g., erosion, urethral obstruction. We studied the effect of the mesh stiffness on urethral mobility at Valsalva maneuver, under impairment of the supporting structures (levator ani and/or ligaments), by using a numerical model...

INTRODUCTION: Overactive bladder (OAB) symptoms (urge, frequency, nocturia) are not generally considered surgically curable by learning institutions. The Integral Theory hypothesizes that OAB is a prematurely activated, but normal micturition reflex caused by loose suspensory ligaments and potentially curable surgically by repairing such ligaments. To test this hypothesis by surgical repair of loose cardinal and uterosacral ligaments in patients with 2(nd) degree or greater uterine/apical prolapse...

Lumbosacral plexopathy is a rare clinical entity that results in potentially severe neurological deficit. The clinical presentation of lumbosacral plexopathy includes motor and sensory deficits. However to the best of our knowledge, hip instability secondary to lumbosacral plexopathy has not been reported in current literature. We report two cases of pelvic injury in which recurrent hip subluxation occurred following fixation of acetabular fractures. We attribute this to inadequate hip muscle tension from the associated lumbosacral plexopathy...
