INTRODUCTION: The incidence of periprosthetic fracture after total knee arthroplasty (TKA) is increasing, and treatment is becoming more necessary. In periprosthetic tibial fracture, the stem of the tibial component largely occupies the medullary canal of the proximal tibia, which limits the selection of implants. The purpose of this study was to evaluate the effectiveness of the minimally invasive plate osteosynthesis (MIPO) technique with locking plates for periprosthetic tibial fractures after TKA...

OBJECTIVES: In today's climate of cost containment and fiscal responsibility, generic implant alternatives represent an interesting area of untapped resources. As patents have expired on many commonly used trauma implants, generic alternatives have recently become available from a variety of sources. The purpose of this study was to examine the clinical and economic impact of a cost containment program using high quality, generic orthopaedic locking plates. The implants available for study were anatomically precontoured plates for the clavicle, proximal humerus, distal radius, proximal tibia, distal tibia, and distal fibula...

REVIEW
Åshild Bjørnerem
Cortical bone is not compact; rather it is penetrated by many Haversian and Volkmann canals for blood supply. The lining of these canals are the intracortical bone surfaces available for bone remodeling. Increasing intracortical bone remodeling increases cortical porosity. However, cortical bone loss occurs more slowly than trabecular loss due to the fact that less surface per unit of bone matrix volume is available for bone remodeling. Nevertheless, most of the bone loss over time is cortical because cortical bone constitutes 80% of the skeleton, and the relative proportion of trabecular bone diminishes with advancing age...

We report two cases of failed attempts at closed reduction of high-energy tibial fractures with an associated fibula fracture. The first case was a 39-year-old male involved in high-speed motorbike collision, while the second was a 14-year-old male who injured his leg following a fall of three metres. Emergency medical services at the scenes of the accidents reported a 90-degree valgus deformity of the injured limb and both limbs were realigned on scene and stabilized. Adequate alignment of the tibia could not be achieved by manipulation under sedation or anaesthesia...

Locoregional anesthetic techniques may be a very useful tool for the anesthetic management of wallabies with injuries of the pelvic limbs and may help to prevent capture myopathies resulting from stress and systemic opioids' administration. This report describes the use of ultrasound-guided femoral and sciatic nerve blocks in Bennett's wallaby (Macropus rufogriseus) referred for orthopaedic surgery. Ultrasound-guided femoral and sciatic nerve blocks were attempted at the femoral triangle and proximal thigh level, respectively...

CONTEXT: Peak bone mass (PBM) and strength are important determinants of fragility fracture risk in later life. During growth bone is responsive to changes in nutrition and physical activity (PA), particularly when occuring before pubertal maturation. OBJECTIVE: In prepubertal healthy boys, protein intake (Prot-Int) enhances the impact of PA on weight-bearing bone. We hypothesized that the synergism between Prot-Int and PA on proximal femur as recorded at mean age of 7...

Bone loss is a common comorbidity of inflammatory bowel disease (IBD), leading to elevated fracture risk in these patients. Inflammatory factors associated with IBD cause increased bone resorption and decreased bone formation with multiple factors implicated as instigators of these alterations. In this project, we examined the influence of IBD on osteocytes proteins in male rats (2 months old) divided into two groups: induced gut inflammation via TNBS enema and vehicle control. We examined the prevalence of two pro-inflammatory cytokines, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), an anti-inflammatory cytokine, interleukin-10 (IL-10), the anabolic factor insulin-like growth factor-I (IGF-I), osteoclastogenesis regulators RANKL and OPG, and the bone formation inhibitor sclerostin in osteocytes in three bone compartments 4 weeks after initiation of gut inflammation...

BACKGROUND: Roughly focused extracorporeal shock waves therapy (ESWT) is characterized by a wide focal area, a large therapy zone, easy positioning, and less pain during treatment. The purpose of this study was to investigate the effects of roughly focused ESWT on the expression of osteoprotegerin (OPG) and bone morphogenetic protein-2 (BMP-2) in osteoporotic fractures in rats. METHODS: Seventy-two female Sprague-Dawley (SD) rats, 3 months old, were divided into sham-operated group (n = 6) and an ovariectomized (OVX) group (n = 66)...

Intramedullary nail and plate combination techniques have been described mostly for use in the proximal tibia. However, the nail and plate combination technique can also be used in the distal tibia, to counteract the deforming forces that cause construct failure and nonunion. In this article, we review pertinent anatomy and biomechanics and offer case examples that highlight the indications and applications of the nail and plate combination technique for distal tibia fractures.

INTRODUCTION: Leiomyoma is benign smooth-muscle tumor most commonly arising in the uterus, the gastrointestinal tract, and the skin. Leiomyomata are infrequently seen in the extremities and rarely seen in the bone. It is usually presented by a gradually increasing pain with nonspecific radiological findings, and could be a differential diagnosis for wide range of bone tumors. CASE PRESENTATION: We report a case of a 73-year-old Japanese female patient with a painful intraosseous leiomyoma involving the proximal tibia...

INTRODUCTION: Chronic osteomyelitis is a disease that requires fastidious treatment to eliminate. However, when eradication is unable to be achieved through exhaustive modalities of antibiotic therapy and multiple debridements, significant resection of the infected bone and soft tissue must be considered, including amputation. Here we report of a salvage procedure for chronic osteomyelitis of the left tibia by employing a rotationplasty to avoid an above knee amputation and instead provide the patient with a below knee amputation...

High-energy fractures of the proximal tibia with extensive fragmentation of the posterior rim of the tibial plateau are challenging. This technique aims to describe a method on how to embrace the posterior rim of the tibial plateau by placing a horizontal precontoured one-third tubular plate wrapped around its corners. This method, which we named "hoop plating," is mainly indicated for cases of crushed juxta-articular rim fractures, aiming to restore cortical containment of the tibial plateau. Through a lateral approach with a fibular head osteotomy (Lobenhoffer approach), both anterolateral and posterolateral fragments are directly reduced and supported by a one-third tubular plate of adequate length...

Pseudoarhtrosis is a relatively frequent complication of fractures, in which the lack of mechanical stability and biological stimuli results in the failure of bone union, most frequently in humerus and tibia. Treatment of recalcitrant pseudoarthrosis relies on the achievement of satisfactory mechanical stability combined with adequate local biology. Herein we present two cases of atrophic pseudoarthrosis that received a Tissue Engineering Product (TEP) composed of autologous Bone Marrow-derived Mesenchymal Stromal Cells (BM-MSC) combined with deantigenised trabecular bone particles from tissue bank...

BACKGROUND: A lateral approach with open reduction and internal fixation with a plate is a very effective technique for the majority of distal fibular fractures. However, this open approach for ankle fixation may be complicated by wound dehiscence and infection, especially in high-risk patients. An alternative to plating is an intramedullary implant, which allows maintenance of length, alignment, and rotation and which allows for decreased soft tissue dissection. While there has been clinical data suggesting favorable short-term outcomes with these implants, there is no current biomechanical literature investigating this technology in this particular fracture pattern...
