BACKGROUND: Osteopenia of the front half of the distal femur is a well-known problem after total knee arthroplasty (TKA) with secondary issues after years, especially when must be addressed fractures or revisions for loosening. Stress shielding has been recognized as a cause in different biomechanical studies of the bone. QUESTION/PURPOSES: It was logical to look for a solution by changing the design to minimize stress shielding behind the femoral shield. PATIENTS AND METHODS: It was proved that radiological measure of bone density was reliable although not so early and accurate as densitometry...

PURPOSE: To determine how the reduction of medial and anteromedial cortices using CT findings in 31-A2 intertrochanteric fractures treated with the intramedullary nail could affect the clinical outcomes and complication rates of the fractures. METHODS: We retrospectively analyzed the data of 43 patients with 31-A2 intertrochanteric fractures who underwent closed reduction and intramedullary internal fixation (CRIF) between January 2010 and December 2013. Patients were classified into two groups based on the post-operative CT scans taken from the sagittal and coronal planes, respectively...

BACKGROUND: Iliac vein injury associated with pelvic fracture due to blunt trauma is an uncommon and difficult diagnosis but a life-threatening condition which often requires an emergent management. Although open repair has been traditionally used as the treatment of choice in unstable patients, it is controversial, given the difficulty injured vessel exposure in patients with significant retroperitoneal hematoma as well as tamponade effect loss associated to laparotomy. We present a challenging case of iliac vein laceration successfully treated by placement of a self-expanding covered stent...

The majority of hip fractures have been reported to occur as a result of a fall with impact to the greater trochanter of the femur. Recently, we developed a novel cadaveric pendulum-based hip impact model and tested two cadaveric femur-pelvis constructs, embedded in a soft tissue surrogate. The outcome was a femoral neck fracture in a male specimen while a female specimen had no fracture. The aim of the present study was, first, to develop a methodology for constructing and assessing the accuracy of explicit Finite Element Models (FEMs) for simulation of sideways falls to the hip based on the experimental model...

Although several studies highlight the advantages of robotic arm-assisted total knee arthroplasty (RA-TKA), few investigate its intraoperative outcome. Therefore, the purpose of this study was to analyze the RA-TKA's ability to assist with intraoperative correction of: (1) flexion and (2) extension gaps, as well as its ability to (3) accurately predict implant sizes. Additionally, in this RA-TKA cohort, length of stay, complications, and readmissions were assessed. A total of 335 patients who underwent RA-TKA were included...

Curative effect of artificial femoral head replacement on hip joint function and complications of elderly patients with femoral intertrochanteric fracture were investigated. Eighty patients who were operated for femoral intertrochanteric fractures operation were randomly divided into observation group (n=40) and control group (n=40). The observation group was treated with artificial femoral head replacement, while the control group received internal proximal femur locking plate fixation. In the observation group, the operation time was shorter than that in the control group (P<0...

BACKGROUND: Outcomes following revision surgery for scaphoid nonunions with osteonecrosis are guarded. We hypothesized that use of free vascularized medial femoral condyle (MFC) bone grafts can lead to healing of the nonunion, increase vascularity of the proximal pole, and restore scaphoid architecture, resulting in acceptable functional outcomes. METHODS: We performed a retrospective review of 49 patients who were treated with an MFC bone graft, between May 2005 and September 2016, after prior failure of operative treatment for scaphoid nonunion...

We compared the effectiveness of promoting bone healing between two teriparatide preparations for atypical femoral fracture (AFF). A total of 45 AFFs were included in this study, and we compared the duration of bone union. Teriparatide administered by daily injection enhanced bone union more than weekly administration in complete AFFs. INTRODUCTION: The efficacy of teriparatide for atypical femoral fracture (AFF) has been recently reported. Although two different teriparatide preparations can be used to treat osteoporosis in Japan, daily or weekly injection, all previous reports on the effectiveness of teriparatide for AFF only examined daily injection formulations...

The release of fat and bone marrow fragments is a common occurrence following traumatic and nontraumatic events. In most cases, they go symptomless or cause only minor disturbances, but occasionally they can determine a multiorgan dysfunction whose severity ranges from mild to fatal. The authors describe the case of a patient who became deeply comatose and ultimately died after a traffic accident in which he suffered the exposed right femoral and tibial fracture in the absence of other injuries. He underwent the external fixation of the fractured bones 2 hours after the admission under general anesthesia...

Recent estimates suggest an annual incidence of greater than 125,000 femoral neck fractures. Surgical treatment is indicated for the majority of these fractures, which are estimated to double by the year 2050. Most displaced femoral neck fractures in elderly patients are treated with arthroplasty secondary to high complication rates associated with internal fixation. Traditional implants used for internal fixation, typically in elderly patients with stable fracture morphology and younger patients regardless of morphology, include the sliding hip screw (SHS), with or without a supplemental anti-rotation screw, and multiple cancellous lag screws...

BACKGROUND: The Unified Classification System (UCS) for Periprosthetic femoral fractures (PPFF) still has some limitations. METHODS: We retrieved 18 previous classifications for PPFF based on systematic review of the literature, and also retrospectively analyzed 402 cases with PPFF. 46 cases (11.4%) were identified as beyond the classification scope of the original UCS. RESULTS: We modified the UCS as follows: (1) add two new B2 subtypes: B2PALT/B2PAGT (i...

BACKGROUND: Histamine regulates function of osteoclasts and osteoblasts, however data regarding the influence of histamine H2 receptors antagonists on bone tissue are ambiguous. Factors that influence growing skeleton may have an important impact on the peak bone mass and future risk of fractures. The aim of our study was the assessment of influence of ranitidine, on growing bones. METHODS: The experiment was carried out on young male Wistar rats divided into two groups receiving either ranitidine (10 mg/kg ip) or vehicle...

Purpose: Bisphosphonate (BP) is the first-line therapy for the management of osteoporosis. BP-related osteonecrosis of the jaw (BRONJ) and atypical femoral fracture (AFF) are increasingly common comorbidities in patients with osteoporosis under long-term BP treatment. The aim of this study was to evaluate the incidence and risk factors for AFF features on bone scintigraphy in patients with BRONJ. Methods: Among total of 373 BRONJ patients treated between September 2005 and July 2014, 237 (220 women, 17 men; median age 73 years) who underwent three-phase bone scintigraphy were enrolled for this retrospective study...

The trabecular bone score (TBS) is a novel tool using grayscale variograms of the lumbar spine bone mineral density (BMD) to assess trabecular bone microarchitecture. Studies in patients with chronic kidney disease (CKD) suggest it may be helpful in assessing fracture risk. However, TBS has not been validated as a measure of trabecular architecture against transiliac bone biopsy with histomorphometry in CKD patients. We hypothesized that TBS would reflect trabecular architecture at the iliac crest in CKD patients...
