Osteoporosis is related to more than 2 million fractures and $19 billion in healthcare costs each year (). A fragility fracture (FF) is a low-energy fracture of the distal radius, proximal humerus, ankle, or proximal femur (hip) from minimal trauma such as a fall from a standing height. In addition to cost, FFs often result in the loss of independence and productivity (). In 2015, our orthopaedic unit received the first certification ever awarded for FFs. Fragility fracture certification is a new certification demonstrating that a healthcare facility complies with national patient care standards and uses evidence-based practice guidelines to deliver quality outcomes...

BACKGROUND: Patients with facial fracture or head and neck surgery sometimes suffer from infraorbital nerve injury. This injury results in severe hemilateral numbness in the midfacial area. The infraorbital nerve ends with two major branches; the infra nasal branch (INB) and superior labial branch (SLB). In this study, we assessed the feasibility of cross-nerve transfer of the INB and SLB based on a cadaver study. METHODS: The INB/SLB from a total 20 sides of 10 cadavers (2 men and 8 women; average age, 79...

The phosphatase PHOSPHO1 is involved in the initiation of biomineralisation. Bones in Phospho1 knockout (KO) mice show histological osteomalacia with frequent bowing of long bones and spontaneous fractures: they contain less mineral, with smaller mineral crystals. However, the consequences of Phospho1 ablation on the microscale structure of bone are not yet fully elucidated. Tibias and femurs obtained from wild-type and Phospho1 null (KO) mice (25-32 weeks old) were embedded in PMMA, cut and polished to produce near longitudinal sections...

BACKGROUND: Fall-related deaths continue to be the leading cause of accidental deaths in the older adult (65+ year) population. However, many fall-related fatalities are unspecified and little is known about the fall characteristics and personal demographics at the time of the fall. Therefore, this report describes the characteristics, circumstances and injuries of falls that resulted in older adult deaths in one U.S. County and explores the variables associated with fatal injuries from falls...

Those with type 1 diabetes (T1D) are more likely to suffer a fracture than age- and sex-matched individuals without diabetes, despite daily insulin therapy. In rodent studies examining the effect of bone- or glucose-targeting therapies on preventing the T1D-related decrease in bone strength, insulin co-therapy is often not included, despite the known importance of insulin signaling to bone mass accrual. Therefore, working toward a relevant pre-clinical model of diabetic bone disease, we assessed the effect of continuous subcutaneous insulin infusion (CSII) therapy at escalating doses on preserving bone and the effect of delayed CSII on rescuing the T1D-related bone deterioration in an established murine model of T1D...

We retrospectively reviewed outcomes of 79 patients with periprosthetic hip fractures around cemented tapered polished stem (CTPS) implants treated with osteosynthesis between January 1997 and July 2011. All patients underwent open reduction and fixation using a broad dynamic compression plate (DCP). Seventy two (91%) of fractures united. There were seven (9%) non-unions with failure of metal work, three (4%) as a result of infection and four (5%) due to mechanical failure. Significant subsidence (>5mm) of the implant was seen in seven (9%) of cases...

BACKGROUND: Minimally invasive surgical operation of intramedullary (IM) nailing is a standard technique for treating diaphyseal fractures. However, in addition to its advantages, there are some drawbacks such as the frequent occurrence of malalignment, physical fatigue and high radiation exposure to medical staff. The use of robotic and navigation techniques is promising treatments for femoral fractures. MATERIALS AND METHODS: This paper presents a novel robot-assisted manipulator for femoral shaft fracture reduction with indirect contact with the femur...

BACKGROUND: More than a million surgeries are performed annually in the United States for hip or knee arthroplasty or hip fracture stabilization. One-fifth of these patients have blood transfusions during their hospital stay. Increases in transfusion rates have caused concern about increased adverse events from unnecessary transfusions. METHODS: We systematically reviewed randomized trials examining the effect of restrictive vs liberal transfusion thresholds on patients having major orthopedic surgery...

BACKGROUND: The hip is a common location for metastatic tumors. Due to the high loads placed through the proximal femur, surgery is often indicated to provide pain relief and restore function. Historically, these lesions are reconstructed with a hemiarthroplasty; however, there are few reports on the outcome of these reconstructions. The purpose of this study is to evaluate the outcome of hemiarthroplasty for the treatment of proximal femur metastatic disease, with a specific focus on the rates of conversion to total hip arthroplasty (THA)...

INTRODUCTION: There has been a debate on the use of ceramic-on-ceramic coupling with the retained femoral stem in isolated acetabular revision. The purpose of this study was to retrospectively review the results and complications of isolated revision of the acetabular component using alumina-on-alumina bearings. METHODS: Between August 2010 and December 2013, 22 patients (23 hips) with a mean age of 60.74 years (40-73) underwent isolated revision of the acetabular component from metal-on-polyethylene to alumina-on-alumina bearings without using a metal sleeve on the undamaged trunnion...

Pioglitazone use is associated with an increased risk of fractures. In this randomized, placebo-controlled study, pioglitazone use for 12 months was associated with a significant increase in bone marrow fat content at the femoral neck, accompanied by a significant decrease in total hip bone mineral density. The change in bone marrow fat with pioglitazone use was predominantly observed in female vs. male participants. INTRODUCTION: Use of the insulin sensitizer pioglitazone is associated with greater fracture incidence, although the underlying mechanisms are incompletely understood...

Fracture healing recapitulates many aspects of developmental osteogenesis. The hedgehog (Hh) signaling pathway, essential to skeletal development, is upregulated during fracture healing, although its importance is unclear. Our goal was to assess the functional importance of Hh signaling in endochondral fracture healing. We created closed, transverse diaphyseal femur fractures in mice, stabilized with an intramedullary pin, and administered a systemic Hh inhibitor or vehicle. Because Hh pathway activation is mediated by the receptor Smoothened (Smo), we used the Smo antagonist GDC-0449 (GDC, 50mg/kg, twice daily) to target the pathway...

Osteoporosis is a common bone disease characterized by low bone mass and altered bone microarchitecture, resulting in decreased bone strength with an increased risk of fractures. In clinical practice, physicians can assess the risk of fracture for a patient based on several risk factors. Some such as age, weight, and history of fractures after 50 years of age, parental fracture, smoking status, and alcohol intake are incorporated into FRAX, an assessment tool that estimates the 10-year probability of hip fracture and major osteoporotic fractures based on the individual's risk factors profile...

BACKGROUND: The use of porous tantalum for the acetabular component in primary total hip arthroplasty (THA) has demonstrated excellent short-term and midterm results. However, long-term data are scarce. The purpose of this prospective study is to report the long-term clinical and radiologic outcome following use of an uncemented porous tantalum acetabular component in primary THA with a minimum follow-up of 17.5 years, in a previously studied cohort of patients. METHODS: We prospectively followed 128 consecutive primary THAs in 140 patients, between November 1997 and June 1999...

BACKGROUND: Primary hemiarthroplasty was recommended by some surgeons as the preferred choice in treating unstable senile intertrochanteric fractures with osteoporosis. However, many studies reported that proximal femoral nail antirotation (PFNA) currently was as an optimal implant for the treatment of different type of intertrochanteric fractures. Which method is better for treating senile intertrochanteric fractures remains controversial due to the insufficient clinical evidences. METHODS: We reviewed all consecutive senile intertrochanteric fractures treated with PFNA or cemented hemiarthroplasty at our institution between July 2010 and March 2015...

This is the first study to directly compare the original and recently updated versions of the trabecular bone score (TBS) algorithm. We confirmed improved performance of the new algorithm, especially among men. INTRODUCTION: Lumbar spine trabecular bone score (TBS) predicts major osteoporotic fractures (MOFs) and hip fractures (HFs) independent of bone density. The original TBS algorithm (version 1; [TBS-v1]) was optimized for women of average body size. Limitations were identified when used in men or extremes of body mass index (BMI)...

Training of young surgeons in total hip arthroplasty (THA) is crucial, but might affect operative time and outcome especially in minimally invasive (MIS) THA. We asked whether the learning curve of orthopaedic residents trained on MIS THA has an impact on (1) operative time (2) complication rates and (3) early postoperative outcome. In a retrospective analysis of over 1000 MIS THAs from our institutional joint registry, operative time, complication rates, patient reported outcome measures (Western Ontario and McMaster Universities Arthritis Index [WOMAC] and Euro-Qol 5D-5L [EQ-5D]) within the first year and responder rates for positive outcome as defined by the Outcome Measures in Rheumatology and Osteoarthritis Research Society International consensus responder (OMERACT-OARSI) criteria were compared between trainee and senior surgeons...
