When and How to Operate Fragility Fractures of the Pelvis?

Fragility fractures of the pelvis (FFP) are an entity with an increasing frequency. The characteristics of these fractures are different from pelvic ring fractures in younger adults. There is a low energy instead of a high energy trauma mechanism. Due to a specific and consistent decrease of bone mineral density, typical fractures in the anterior and posterior pelvic ring occur. Bilateral sacral ala fractures are frequent. A new classification system distinguishes between four categories with increasing los...

Complications Following Internal Fixator in the Treatment of Pelvic Fracture.

The aim of this systematic review was to investigate the incidence of complications of the internal fixator in the treatment of anterior pelvic ring injury. The literature was comprehensively searched from 1980 to January 2017 to identify potential studies. Six studies involving 272 cases of anterior pelvic ring injury treated with the internal fixator were included in this meta-analysis. The rates of wound infection, heterotopic ossification, nerve paresthesia, pain, and fracture dislocation were 5.7%, 35....

Increased risk of pelvic fracture after radiotherapy in rectal cancer survivors: A propensity matched study.

To determine whether radiotherapy (RT) can increase pelvic fracture risk in rectal cancer survivors. Rectal cancer patients who underwent curative surgery between 1996 and 2011 in Taiwan were retrospectively studied using the National Health Insurance Research Database (NHIRD) of Taiwan. ICD-9 Codes 808, 805.4-805.7, 806.4-806.7, and 820 (including pelvic, sacrum, lumbar, and femoral neck fracture) were defined as pelvic fracture. Propensity scores for RT, age, and sex were used to perform one-to-one matche...

Intraoperative Imaging in Pelvic Surgery.

Pelvic fractures may range from highly severe, life-threatening injuries to less acute clinical entities. There are several sub-entities that are summed up as pelvic injuries. Anatomically, there are fractures of the anterior or posterior pelvic ring. Apart from these, there are fractures of the acetabulum that make up about one fifth of all pelvic injuries. The indication for surgical treatment of pelvic ring injuries depends on the type of injury, involvement of anterior and/or posterior elements of the p...

Imaging of Pelvic and Femoral Fixation Hardware: Normal Findings and Hardware Failure.

Good outcomes following treatment of pelvic ring injuries, acetabular fractures, and femur fractures rely on restoration of native pelvic or limb alignment, anatomical reduction and rigid stability of articular fractures, and early postoperative mobilization. Multiple surgical approaches, reduction aids, and orthopaedic implants are available to stabilize these fractures. Despite best practices, complications including hardware failure, nonunions, malunions, and infections occur. This article discusses comm...

Anterior subcutaneous internal fixator (INFIX) versus plate fixation for pelvic anterior ring fracture.

The aim of this study was to compare the clinical outcomes in patients with unstable anterior pelvic ring fractures after treatment with anterior subcutaneous internal fixator (INFIX) or plate fixation. We performed a retrospective study from August 2015 to October 2017. A consecutive series of 74 patients who underwent surgical treatment of their anterior pelvic ring (35 treated with INFIX and 39 treated with plates) were studied. Data collected included patients' demographic data, injury severity score (I...

In-hospital mortality of pelvic ring fractures in older adults now and then: A pelvic registry study.

With the predicted demographic change, the treatment of geriatric patients will become a major issue for health systems worldwide. The majority of pelvic ring fractures occur in older adults, and their treatment might be associated with a distinct mortality. Herein, we analyzed the data of 5665 patients with pelvic ring fractures aged ≥60 years included in the German Pelvic Trauma Registry from 1991 to 2013.

Conventional plate fixation versus minimally invasive modified pedicle screw-rod fixation for anterior pelvic ring fractures.

There are various methods of fixation for anterior pelvic ring fractures. We report our experience with modified pedicle screw-rod fixation (MPSRF) via a minimally invasive method. Fourteen patients with anterior pelvic ring fracture were treated by internal fixation (conventional plate fixation, n = 7; MPSRF, n = 7). Intraoperative blood loss, operative time, post-operative fracture reduction grading by radiography, and complication rates were compared and statistically analyzed. Patients treated with MPSR...

From rigid bone plate fixation to stable dynamic osteosynthesis in mandibular and craniomaxillo-facial surgery: historical evolution of concepts and technical developments.

Historically, extensive observation of limb fracture healing led to a consensus that only complete rigid immobilization could guarantee recovery. This agreement was arrived at because for a long time progress in treatment was driven by clinicians and did not stem from the application of biological research. The clinical approach was based on immobilization of the fracture by rigid osteosynthesis plates and bicortical screws. Subsequently, after extrapolation of the ideas of Lane, the concept of rigid compre...

In vivo study of the efficacy, biosafety, and degradation of a zinc alloy osteosynthesis system.

In this study, a comprehensive analysis of a novel zinc alloy osteosynthesis system in a canine mandibular fracture model is presented. The efficacy of the system was compared for PLLA (poly-L-lactic acid) and titanium materials using X-ray radiography, micro-CT tomography, undecalcified bone histomorphometry, and a three-point bending test. Histology, blood normal, blood biochemical, and serum zinc concentration tests were also performed to assess the biosafety of the zinc alloy osteosynthesis system. The ...

Relation Between Sacroilium and Other Pelvic Fractures Based on Real-World Automotive Accidents.

The study firstly aimed at looking whether sacroilium (SI) fractures could be sustained as unique pelvic injuries in side impact real world automotive accidents. Secondarily, the sacroilium fractures observed in conjunction with other pelvic fractures were analyzed to investigate the existence of injury association patterns. Two real world accident databases were searched for SI fractures. The occupants selected were front car passengers older than 16, involved in side, oblique or frontal impact, with AIS2+...

Biomechanical Evaluation of Mandibular Condyle Fracture Osteosynthesis Using the Rhombic Three-Dimensional Condylar Fracture Plate.

The aim of the present study was to evaluate the biomechanical stability of osteosynthesis in mandibular condyle fractures using a newly designed rhombic 3-dimensional (3D) condylar fracture plate and compare it with that using standard two 4-hole miniplates and in nonfractured condyles.

Pelvic ring injury in the elderly: Fragile patients with substantial mortality rates and long-term physical impairment.

Pelvic ring injuries in the elderly often occur after low-energy accidents. They may result in prolonged immobilization, complications and an intense rehabilitation process. The aim of this study was to assess mortality, physical functioning and quality of life (QoL) in elderly patients with pelvic ring injuries.

Subject-specific ex vivo simulations for hip fracture risk assessment in sideways falls.

The risk of hip fracture of a patient due to a fall can be described from a mechanical perspective as the capacity of the femur to withstand the force that it experiences in the event of a fall. So far, impact forces acting on the lateral aspect of the pelvic region and femur strength have been investigated separately. This study used inertia-driven cadaveric impact experiments that mimic falls to the side from standing in order to evaluate the subject-specific force applied to the hip during impact and the...

The Pelvis-First Approach for Robotic Proctectomy in Patients with Redundant Abdominal Colon.

Robotic surgery is increasingly performed for low rectal cancer.1 A redundant sigmoid colon makes retraction and pelvic dissection challenging. We present a 'pelvis-first' approach to robotic proctectomy where pelvic dissection occurs prior to colonic mobilization.

Effectiveness and postoperative wound infection of preperitoneal pelvic packing in patients with hemodynamic instability caused by pelvic fracture.

Despite the use of a multidisciplinary treatment approach, the mortality rate of hemodynamic instability due to severe pelvic fracture remains 40-60%. Several recent studies have shown that preperitoneal pelvic packing (PPP) was useful for achieving hemostasis in these patients in the acute phase. However, few studies have examined postoperative complications. The purpose of the present study was to evaluate clinical outcomes and wound infections of PPP in these patients.

Prospective study on image-guided navigation surgery for pelvic malignancies.

Surgery of advanced tumors and lymph nodes in the pelvis can be challenging due to the narrow pelvic space and vital surrounding structures. This study explores the application of a novel electromagnetic navigation system to guide pelvic surgery.

Urethral Trauma following Pelvic Fracture from Horseback Saddle Horn Injury versus other Mechanisms of Pelvic Trauma.

To examine the rate of urethral trauma and pubic symphysis diastasis in saddle horn injury, which occurs when horseback riders are bucked into the air and land with their perineum striking the rigid saddle horn, compared to pelvic fracture from other mechanisms.

The sidestep cutting manoeuvre requires exertion of lumbosacral lateral flexion torque to avoid excessive pelvic obliquity.

During sidestep cutting, the pelvis is supported only on one side; this affects the athlete's posture. This study investigated the mechanism to avoid excessive pelvic obliquity during sidestep cutting. Ten physically active men performed sidestep cutting with maximal effort, and we captured the kinematics and kinetics with force platforms and an eight-camera motion capture system. Our results indicated that the stance hip exerted little abduction torque; however, lumbosacral lateral flexion torque was exert...

Triplane Fractures of the Distal Tibial Epiphysis - Contributions of CT Scans to Indication and Planning of Osteosynthesis.

PURPOSE OF THE STUDY The triplane fracture of the distal tibial epiphysis is characterised by the fracture line in typical three planes which can, however, differ case by case. The authors use the CT imaging as the perfect examination method to determine the nature of the fracture to plan the osteosynthesis. MATERIAL AND METHODS In the five-year retrospective study of a group of patients treated at their own department in the period 2011-2015 the authors assess a total of 55 patients with a triplane fractur...

Strategies for the management of hemodynamically unstable pelvic fractures: From preperitoneal pelvic packing to definitive internal fixation.

Preperitoneal pelvic packing is useful, and favorable treatment outcomes have been reported. However, the timing of subsequent internal fixation of the pelvis is still debatable. We report the outcomes of a study on patients that underwent internal fixation after preperitoneal packing.

Spontaneous reduction of an incarcerated gravid uterus after myomectomy in the second trimester: A case report.

During a normal pregnancy, in the 1st trimester uterus lies in pelvis and enlarges in size as the pregnancy advances. By 14 weeks of gestation, the gravid uterus transforms from a pelvis to an abdominal organ and a retroverted uterus will correct as the fundus rises out of the pelvis and falls forward to its normal anatomical position. If the uterus remains in the pelvic cavity after 14 weeks of gestation, it is referred to as an incarcerated uterus.

Physiological in vitro sacroiliac joint motion: a study on three-dimensional posterior pelvic ring kinematics.

The sacroiliac joint (SIJ) is a well-known source of low back and pelvic pain, of increasing interest for both conservative and surgical treatment. Alterations in the kinematics of the pelvis have been hypothesized as a major cause of SIJ-related pain. However, definitions of both the range and the extent of physiological movement are controversial, and there are no clear baseline data for pathological alterations. The present study combined a novel biomechanical setup allowing for physiological motion of t...

A simple fluid dynamic model of renal pelvis pressures during ureteroscopic kidney stone treatment.

Ureteroscopy is an endoscopic kidney stone removal procedure which increases the internal pressure in the renal pelvis, the kidney's urinary collecting system. Elevated renal pelvic pressure may result in systemic absorption of irrigation fluid and urine, which can increase the risk of postoperative fever and sepsis. Urologists have investigated the effects of various surgical parameters on the renal pelvic pressure. However, it still remains unknown which surgical parameter has the most dominant effect on ...
