Osteonecrosis of the femoral head: pathophysiology and current concepts of treatment.

EFORT Open Rev 2019 Mar 15;4(3):85-97. Epub 2019 Mar 15.

Clinic of Orthopaedics and Trauma Surgery, Geneva University Hospitals, Geneva, Switzerland.

Osteonecrosis of the femoral head is a disabling pathology affecting a young population (average age at treatment, 33 to 38 years) and is the most important cause of total hip arthroplasty in this population. It reflects the endpoint of various disease processes that result in a decrease of the femoral head blood flow.The physiopathology reflects an alteration of the vascularization of the fine blood vessels irrigating the anterior and superior part of the femoral head.

Does Extracorporeal Irradiation and Reimplantation After Acetabular Resections Result in Adequate Hip Function? A Preliminary Report.

Clin Orthop Relat Res 2018 Sep;476(9):1738-1748

M. G. Agarwal, M. K. Gundavda, R. Reddy Orthopedic Oncology, P. D. Hinduja Hospital and Medical Research Center, Mumbai, India R. Gupta Orthopedic Oncology, Fortis Hospital, Mohali, India.

Background: Pelvic resections are challenging, and reconstruction of the resected acetabulum to restore mobility and stability is even more difficult. Extracorporeal radiation therapy (ECRT or extracorporeal irradiation) of autograft bone and reimplantation allows for a perfect size match and has been used with some success in the extremities. Although the risk of wound complications in pelvic surgery has discouraged surgeons from using ECRT of autografts in that anatomic site, we believe it may be a reasonable option. Read More

Preoperative planning of femoral head reduction osteotomy using 3D printing model: A report of two cases.

Acta Orthop Traumatol Turc 2019 Jan 29. Epub 2019 Jan 29.

Acıbadem University, School of Medicine, Istanbul, Turkey.

The deformed and enlarged femoral head secondary to hip diseases such as Legg Calve Perthes and Developmental Dysplasia usually causes impingement between the aspherical head and the acetabulum. To restore and reduce the size of enlarged femoral head, a femoral head reduction technique has been described previously. The goal is to obtain a spherical femoral head and to cover the gliding surface with best available cartilage. Read More

Subtraction osteotomy of the humeral head in posterior shoulder dislocation: a case report.

Eur J Orthop Surg Traumatol 2019 May 28;29(4):933-936. Epub 2019 Jan 28.

High Resolution Hospital Ecija, Seville, Spain.

Locked posterior dislocations of the shoulder with an impacted fracture of the humeral head and an articular surface defect greater than 35-40% are generally treated with a femoral head bone graft or prosthesis. We present a case in which a subtraction osteotomy with osteoclasia on the impacted zone was performed to try to make the articular surface of the humeral head congruent and continuous. With a 42-month follow-up, the clinical outcome, in terms of mobility and pain, was very good; X-rays show there was no avascular necrosis of the humeral head nor signs of articular arthrosis.

Association between MTHFR 677C>T polymorphism and vascular complications in sickle cell disease: A meta-analysis.

Transfus Clin Biol 2019 Jan 10. Epub 2019 Jan 10.

Sickle Cell Institute Chhattisgarh, Forest Block-2, Jail Road, Raipur 492001, Chhattisgarh India. Electronic address:

Sickle cell disease (SCD) is considered as a vascular disease due to its chronic vascular manifestations such as leg ulcers, priapism, acute chest syndrome (ACS), stroke, retinopathy, renal insufficiency, pulmonary hypertension, avascular necrosis of the femoral head (AVNF) and splenic infarction. Emerging evidence has shown that the MTHFR 677C>T variant allele is associated with vascular complications (VC) in patients with SCD; however, results from individual studies are inconclusive. The aim of this meta-analysis is to evaluate the association between the MTHFR 677C>T polymorphism and the susceptibility for VC in SCD patients. Read More

Joint replacement surgery in Ghana (West Africa)-an observational study.

Int Orthop 2019 May 24;43(5):1041-1047. Epub 2019 Jan 24.

West Hertfordshire NHS Trust, St. Joseph's Orthopaedic Hospital, Koforidua, Ghana.

Introduction: With the continued and effective transfer of orthopaedic knowledge and skills across continents, the incidence of hip and knee replacement surgery has increased in the developing world. More patients are having these procedures done locally rather than having to travel over to the more developed western countries at great financial costs for those who cannot really afford it. We report the data collected by an orthopaedic charity MOTEC LIFE UK which has been offering hip and knee arthroplasty procedures to patients who require them. Read More

Prediction of mechanical behavior of cartilaginous infant hips in pavlik harness: A subject-specific simulation study on normal and dysplastic hips.

J Orthop Res 2019 Mar 12;37(3):655-664. Epub 2019 Feb 12.

Department of Radiology and Diagnostic Imaging, University of Alberta, 2A2.41 WMC, 8440-112 Street, Edmonton, Alberta, T6G 2B7, Canada.

In dysplastic infant hips undergoing abduction harness treatment, cartilage contact pressure is believed to have a role in therapeutic cartilage remodeling and also in the complication of femoral head avascular necrosis. To improve our understanding of the role of contact pressure in the remodeling and the complication, we modeled cartilage contact pressure in cartilaginous infant hips undergoing Pavlik harness treatment. In subject-specific finite element modeling, we simulated contact pressure of normal and dysplastic hips in Pavlik harness at 90° flexion and gravity-induced abduction angles of 40°, 60° and 80°.

Segmentation of the proximal femur in radial MR scans using a random forest classifier and deformable model registration.

Int J Comput Assist Radiol Surg 2019 Mar 2;14(3):545-561. Epub 2019 Jan 2.

School of Health Sciences - Geneva, HES-SO University of Applied Sciences and Arts Western Switzerland, Avenue de Champel 47, 1206, Geneva, Switzerland.

Background: Radial 2D MRI scans of the hip are routinely used for the diagnosis of the cam type of femoroacetabular impingement (FAI) and of avascular necrosis (AVN) of the femoral head, both considered causes of hip joint osteoarthritis in young and active patients. A method for automated and accurate segmentation of the proximal femur from radial MRI scans could be very useful in both clinical routine and biomechanical studies. However, to our knowledge, no such method has been published before. Read More

Grafting, Stripping and Stapling of Helical Peptides from the Dimerization Interface of ONFH-Related Bone Morphogenetic Protein-2.

Protein J 2019 02;38(1):12-22

Department of Orthopedics, The Second Affiliated Hospital of Xi'an Jiao Tong University, Xi'an, 710004, China.

Transforming growth factor-β/bone morphogenetic protein (TGF-β/BMP) signaling plays a fundamental role in embryonic skeletal development and postnatal bone homeostasis. The signaling pivot protein BMP-2 belongs to the TGF-β superfamily and has been implicated in the pathogenesis of osteonecrosis of femoral head (ONFH). The biologically functional BMP-2 is a homodimer that has two tightly packed cores at its dimerization interface; each core is defined by the intermolecular interaction between a helical arm from one monomer and a hydrophobic pocket from another monomer.
