Novais, Department of Pediatric Orthopedic surgery, Boston Children's Hospital, Boston, MA, USA K. Ziebarth, Department of Pediatric Surgery, Inselspital, University of Bern, Bern, Switzerland.

Background: Prophylactic pinning of the asymptomatic and normal-appearing contralateral hip in patients with unilateral slipped capital femoral epiphysis (SCFE) remains controversial. Understanding the minimal 10-year clinical, functional, and radiographic outcomes of the contralateral asymptomatic hip in unilateral SCFE may be helpful in the decision regarding whether the benefits associated with potentially preventing a SCFE are outweighed by the risk of additional surgery.

Questions/purposes: Among patients with SCFE treated with prophylactic pinning of the asymptomatic and contralateral hip, we sought (1) to determine the complications and reoperations; (2) to evaluate the development of cam deformities and the frequency and severity of osteoarthritis progression; and (3) to characterize hip pain and function as measured by the Harris hip score (HHS) and the Hip Disability and Osteoarthritis Outcome Score (HOOS) at minimal 10-year followup.

Background: The kinematic alignment (KA) technique for total knee arthroplasty (TKA) is an emerging implant positioning philosophy that aims to restore constitutional knee anatomy to improve knee kinematics. At present, the KA technique aims to reconstruct native femorotibial (FT) joint alignment, however there is still insufficient consideration towards the inter-individual trochlear anatomy variability. Poor trochlear restoration may compromise clinical outcomes. Read More

Femoral Stem Survivorship in Dorr Type A Femurs After Total Hip Arthroplasty Using a Cementless Tapered Wedge Stem: A Matched Comparative Study With Type B Femurs.

J Arthroplasty 2018 Nov 13. Epub 2018 Nov 13.

Department of Orthopedic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea.

Background: There is a lack of understanding on relationship between the femoral geometry and outcomes of total hip arthroplasty (THA). We investigated clinical and radiographic outcomes of THA using a cementless tapered wedge stem in patients with Dorr type A proximal femoral morphology and compared with those of type B femurs at a minimum follow-up of 5 years.

Methods: We analyzed 1089 hips (876 patients) that underwent THA using an identical cementless tapered wedge stem. Read More

A multi-factorial analysis of bone morphology and fracture strength of rat femur in response to ovariectomy.

J Orthop Surg Res 2018 Dec 13;13(1):318. Epub 2018 Dec 13.

Division of Bio-Prosthodontics, Niigata University Graduate School of Medical and Dental Sciences, Niigata, Japan.

Background: Postmenopausal osteoporosis develops due to a deficiency of estrogen that causes a decrease in bone mass and changes in the macro- and micro-architectural structure of the bone, leading to the loss of mechanical strength and an increased risk of fracture. Although the assessment of bone mineral density (BMD) has been widely used as a gold standard for diagnostic screening of bone fracture risks, it accounts for only a part of the variation in bone fragility; thus, it is necessary to consider other determinants of bone strength. Therefore, we aimed to comprehensively evaluate the architectural changes of the bone that influence bone fracture strength, together with the different sensitivities of cortical and trabecular bone in response to ovariectomy (OVX).

Analysis of Trauma Intensity during Surgical Bone Procedures Using NF-κB Expression Levels as a Stress Sensor: An Experimental Study in a Wistar Rat Model.

Materials (Basel) 2018 Dec 12;11(12). Epub 2018 Dec 12.

Department of Biotechnology, Biotecnos-Technology and Science, Cuareim 1483, Montevideo, Canelones 11100, Uruguay.

It is well known that the transcription factor NF-κB regulates multiple aspects of innate and adaptive immune functions and functions as a pivotal mediator of inflammatory responses. In the present study, we evaluated the trauma generated (inflammatory reaction) after osteotomy bone surgical procedures and placement of implants in the femoral cortical bone of Wistar rats. Surgical stress was evaluated measuring the release and activation of the NF-κB factor. Read More

Laparoscopic transabdominal preperitoneal technique versus open surgery with the ULTRAPRO Hernia System for the repair of female primary femoral hernias-an observational retrospective study.

Medicine (Baltimore) 2018 Dec;97(49):e13575

Department of General Surgery, Linyi People's Hospital, Linyi, Shandong Province, China.

Femoral hernias (FHs), predominantly seen in females, require surgery for cure. To date, surgical repair of primary FHs in female patients with either open surgery or laparoscopic operation has been poorly documented. We retrospectively investigated the treatment of female primary FHs with open surgery using the ULTRAPRO Hernia System (UHS procedure) or the laparoscopic procedure, namely, the transabdominal preperitoneal (TAPP) technique.

Fascia iliaca compartment block versus intravenous analgesic for positioning of femur fracture patients before a spinal block: A PRISMA-compliant meta-analysis.

Medicine (Baltimore) 2018 Dec;97(49):e13502

Graduate Institute of Clinical Medicine.

Background: Fascia iliaca compartment block (FICB) provides an analgesic option for positioning before spinal anesthesia in patients suffering from a femur fracture. The evidence supporting FICB is still not well established. The aim of our study is to assess the efficacy and safety of FICB comparing with intravenous analgesic (IVA) on the quality for positioning before spinal anesthesia in participants with a femur fracture.
