BACKGROUND: In joint revision surgery, bone cement extraction remains a major challenge which even today has not seen a satisfactory solution yet. We studied in an experimental setting the impact of heat sources on the mechanical properties and microstructure of bone cement and determined the glass transition temperature (T G) of bone cement. As a result, it would be possible to establish a thermomechanical method which makes use of the structural and material-specific property changes inherent in bone cement at elevated temperatures...

The alpha-defensin test has demonstrated promising results in studies evaluating it for the diagnosis of prosthetic joint infection. There are limited data in the literature regarding its use in patients with other inflammatory joint conditions, but a high specificity for infection has been reported. We describe a patient with a prosthetic knee joint, who had a positive alpha-defensin lateral flow assay but in whom subsequent results confirmed a diagnosis of acute gout with no evidence of infection.

Rivaroxaban, dabigatran, apixaban and edoxaban are the four available new oral anticoagulants (NOAC) which are currently approved for venous thromboembolism prophylaxis after total hip and knee replacement. Large phase 3 and phase 4 studies comparing NOAC with low molecular weight heparins have shown similar results regarding the efficacy and safety of these two categories of anticoagulants. Management of bleeding complications is a matter of great significance. Three reversal agents have been developed: idarucizumab, andexanet alfa and ciraparantag...

Open reduction and internal fixation of complex proximal humeral fracture represents a surgical challenge. The main objective of this procedure is to anatomically reduce the tuberosities. We propose a standardized and reproducible technique that we apply to all complex displaced 3- and 4-part fractures of patients under 50 years. We use an antero-lateral trans-deltoid approach; the humeral head and the tuberosities are reduced under fluoroscopic control. The tuberosities are stabilized with an inter-tuberosity osteosuture, and we then introduce a thin and straight intra-medullary nail (Telegraph IV FH Orthopedics) at the hinge point of the humeral head...

BACKGROUND: Proximal humerus fractures are common injuries. Locking plates and anterograde medullary nails are the two most common fixation devices used when open reduction and internal fixation (ORIF) is indicated. Complications related to fracture and to hardware are numerous, especially shoulder stiffness. The goal of this study is to report the clinical outcomes of gleno-humeral arthroscopic arthrolysis combined with hardware removal. METHODS: A total of 58 patients (25 men, 33 women) with a mean age of 58 years (24-79) were reviewed retrospectively...

INTRODUCTION: This study evaluates a possible change in the demographics and surgical practice observed in a large cohort of patients undergoing total knee replacement (TKR). PATIENTS AND METHODS: We performed a retrospective analysis of a prospectively collected data on two groups of consecutive patients undergoing primary TKR. Group one consisted of patients who underwent surgery between 1994 and 1998. Group two consisted of patients who had surgery between 2009 and 2012...

The formation of lamellar bone in the soft tissues, where bone normally does not exist, is called myositis ossificans. However, it would be more accurate to describe as myositis ossificans the involvement of skeletal muscles and as ectopic or heterotopic ossification the involvement of soft tissues in general. The lesion is subdivided in genetic and non-genetic or acquired types. Myositis or fibrodysplasia ossificans progressiva is a debilitating rare genetic disorder. Clinical suspicion of the disease in the newborn on the basis of malformed great toes may lead to early clinical diagnosis, confirmatory diagnostic genetic testing and avoidance of iatrogenic harmful procedures...

Medial meniscus posterior root has an important role in the maintenance of knee articular cartilage. Although pullout repair of the medial meniscus posterior root tear has become a gold standard, it has several difficulties for suturing. We have developed a modified Mason-Allen suture technique using the FasT-Fix all-inside suture device combined with Ultrabraid. The present suture technique allows a strong grasping of the medial meniscus posterior horn for arthroscopic pullout repair.

Periprosthetic infection remains one of the most serious complications following megaendoprostheses. Despite a large number of preventive measures that have been introduced in recent years, it has not been possible to further reduce the rate of periprosthetic infection. With regard to metallic modification of implants, silver in particular has been regarded as highly promising, since silver particles combine a high degree of antimicrobial activity with a low level of human toxicity. This review provides an overview of the history of the use of silver as an antimicrobial agent, its mechanism of action, and its clinical application in the field of megaendoprosthetics...

Proximal humerus fractures are characterized by their frequency, the difficulties and the absence of treatment of reference. New means of osteosynthesis appeared since the years 2000, as well as the preferential recourse to the reversed prostheses of shoulder. A chapter is dedicated to classifications, as a whole not very reproducible. The new treatments are represented by the nails, such as Telegraph(®), and the plates with blocked screws. It appeared a real progress in the osteosyntheses and became infinitely more solid with the stability of the screws in the bone...

BACKGROUND: Interest in the direct anterior approach for total hip arthroplasty has increased over recent years; however, the potential for substantial complications exists, especially during the surgeon's learning curve. We evaluated the change in various metrics to help identify a single surgeon's learning curve. Additionally, we examined whether the learning curve was different for primarily arthroplasty versus trauma-trained surgeons. METHODS: We reported outcomes from the first 50 total hip arthroplasties performed through a direct anterior approach by a trauma fellowship-trained orthopaedic surgeon...

INTRODUCTION: Cemented stem remains the gold standard for prosthesis in trauma. The purpose of this study was to evaluate the functional and radiological outcomes of a cementless, trauma-specific locked stem (hemi and reverse) for 3- and 4-part proximal humeral fractures. MATERIALS AND METHODS: One hundred and thirty-four 3- and 4-part fractures have been treated by locked stem, 69 with hemiarthroplasty [mean age 68 years (50-90)] and 65 with reversed [mean age 78 years (66-91)]...

INTRODUCTION: Early ambulation is the principal objective in trans-femoral amputees. Postamputation modifications complicate the rehabilitation process due to a reduced control at the interface between stump and prosthesis. The aim of this study is to determine whether magnetic resonance imaging depicts the amount of fatty degeneration of the thigh muscles after trans-femoral amputation (TFA). METHODS: A total of 12 patients following a TFA on the basis of a bone neoplasm or metastasis with an evaluable postoperative MRI were identified...

Current guidelines suggest early surgical treatment of open fractures. This rule in open hand fractures is not well supported and may be unpractical. Furthermore, desirable debridement and washout can be obtained in the emergency department (ED). The purpose of this study was to evaluate the relationship between the level of contamination, quality of washout in the emergency room, and the development of infection. Sixty-one patients with open fractures of the hand were retrospectively reviewed for demographic and fracture characteristics, and other complications...

INTRODUCTION: The hip placement with a metal-on-metal (MOM) bearing has been used for both surface replacement and total hip arthroplasty (THA). Use of MOM bearing for hip replacement reduces the wear compared to conventional bearings. METHODS: We prospectively assessed 30 patients who underwent unilateral MOM THA. A control group of 30 patients who underwent metal-on-polyethylene THA using the implants as the other group, except for bearing, were accessed. Blood samples were collected preoperatively and at 3- , 6- , 9- , 12- , 15- , 18- , and 24-month intervals...

Inferior dislocation of the hip is a rare clinical entity, wherein closed reduction maneuver could be challenging, especially if the attending surgeon is not familiar with the specific anatomy associated with this injury. Due to the rarity of this type of injury, large case series are lacking in the literature; hence, case reports form the major source of our knowledge regarding the clinical presentation and management. An extensive literature search revealed a change in age group presenting with this specific injury, with a male predilection...

M Vosloo, N Keough, M A De Beer
The rotator cuff (RC) insertions according to most anatomical texts are described as being separate from one another. However, clear fusion of the RC tendon fibres exists with prior studies showing this interdigitation forming a common, continuous insertion onto and around the lesser and greater tubercles (LT and GT) of the humerus. Current surgical repair methods (especially arthroscopic techniques) rarely mention or consider these connections during repair and suture anchor implantation. The general principles of RC surgery remain a controversial subject, due to various available techniques, surgeon experience and preference, and the contradicting success rates...
