INTRODUCTION: The selection of a surgical approach for buttressing posterolateral tibial plateau fractures is controversial. OBJECTIVE: This study compared the surgical exposure area between the reversed L posteromedial approach (R-PM) and the posterolateral (PL) approach using the lateral plateau width as a metric. MATERIALS AND METHODS: Twenty lower extremities from fresh frozen cadavers were included. The R-PM approach was used first and the boundary of the posterior tibial cortex exposure was marked with metal pins...

Most models of osteoporotic bone fractures are performed unilaterally (UL). We investigated healing of tibia osteotomy performed either UL or bilaterally (BL) in ovariectomized rats. Behavior of animals and muscle structure were assessed. Three-month-old female Sprague-Dawley rats were ovariectomized (n = 32). After 10 weeks, half the rats underwent UL osteotomy of tibia metaphysis (right limb) with plate osteosynthesis. The other rats were osteotomized BL. Half of the rats in each group received either standard pain treatment with carprofen (5 mg/kg body weight (BW), 1x/day for 2 days) or carprofen and buprenorphine (5 mg/kg BW, 1x/day and 0...

Objectives: Intramedullary nailing is the treatment of choice for fractures of the tibial shaft, which might necessitate the nail removal due to complications in the long-term. Although considered as a low-risk procedure, intramedullary nail removal is also associated with certain complications. Here, we compared the most commonly used stainless steel and titanium nails with respect to the complications during removal and clinical outcome for intramedullary nailing of diaphyseal fractures of the tibia...

BACKGROUND: The incidence of periprosthetic fractures associated with total knee arthroplasty (PpFxK) has been reported to be 0.3 - 5.5%. 40% of all cases are related to revision TKA. The most common localisation is the distal femur. Classification is performed according to Rorabeck (RB). RB I - II fractures are usually treated with locked plating and retrograde intramedullary nailing, whereas RB III fractures are an indication for revision arthroplasty using a hinged endoprosthesis...

BACKGROUND: Although gunshot-induced extremity fractures are typically not considered open fractures, there is controversy regarding wound management in the setting of operative fixation to limit infection complications. Previous studies have evaluated the need for a formal irrigation and debridement (I&D) prior to intra-medullary nailing (IMN) of gunshot-induced femur fractures but none have specifically evaluated tibias. By comparing primary IMN for tibial shaft fractures caused by low-velocity firearms additionally treated with a formal operative I&D (group 1) with those without an I&D (group 2), we sought to identify whether there are: differences in treatment group infection rates; particular fracture patterns more prone to infection; and patient characteristics more prone to infections...

BACKGROUND: Proximal tibia fractures are one of the most familiar fractures. Surgical approaches are usually needed for anatomical reduction. However, no single treatment method has been widely established as the standard care. Our present study aims to compare the stress and stability of intramedullary nails (IMN) fixation and double locking plate (DLP) fixation in the treatment of extra-articular proximal tibial fractures. METHODS: A three-dimensional (3D) finite element model of the extra-articular proximal tibial fracture, whose 2-cm bone gap began 7 cm from the tibial plateau articular surface, was created fixed by different fixation implants...

BACKGROUND: osteogenesis needs circulation of blood in the bones. Bone growth, repair of fracture, maintenance of bone vitality and other injures also need blood circulation in proper way. Blood is allowed to flow via holes in the diaphysis, which are called as nutrient foramina. METHODS: The crosssectional study was done in the department of Anatomy, Ayub and Khyber Medical College (Osteology Sections). The aim was to observe diaphyseal nutrient foramina in the human long bones of the lower limb...

The formulation of appropriate postoperative strategies, following fracture repair, currently involves an understanding of radiological and clinical outcome measures. This study has evaluated several modalities used to assess the progression of bone healing in a sheep tibial segmental defect model. Measures of defect optical density and volumetric data including bone density (BD), bone volume (BV) and bone mass (BM) were compared with qualitative data involving visual appraisal of radiographs [% bridging callus and modified radiographic union score tibia (mRUST)] and a clinical outcome measure (locomotory function)...

RATIONALE: Although numerous reconstruction protocols have been reported for lower leg trauma, those for distal leg trauma remain few. We present the case of a woman with an implant exposure wound, who was successfully treated through fat grafting, without major flap surgery. PATIENT CONCERNS: An 83-year-old woman with an exposed implant in lower extremity received reconstruction surgery once and the surgery failed. She refused additional major surgery and negative pressure wound therapy...

INTRODUCTION: Anterior knee pain can be chronic sequelae of intramedullary nailing of the tibia. Several causes have been identified; no single reason can fully explain the occurrence. We, therefore, set out to find the rate of anterior knee pain in our practice and if any relationship exists between the anterior knee pain and extensor muscle strength. METHODOLOGY: A total of 72 knees in 36 patients with no prior history of knee pain, but had unilateral tibiofibular fracture, who had internal fixation with interlocking intramedullary nailing done and were followed up for at least 1 year were recruited into the study...

Metastasis of cancer to the skeleton represents a debilitating turning point in the lives of patients. Skeletal metastasis leads to moderate to severe ongoing pain along with bone remodeling that can result in fracture, events that dramatically diminish quality of life. IL-6 levels are elevated in metastatic breast cancer patients and are associated with a lower survival rate. We therefore determined the consequences of inhibition of IL-6 signaling using a novel small molecule antagonist, TB-2-081, on bone integrity, tumor progression, and pain in a rodent model of breast cancer...

The mechanical properties of the bone play a decisive role in the resistance of the bone to fracture. Clinically, the quantity of the bone in the mineral phase has been considered as the gold-standard indicator for the risk of bone fracture. However, the bone is a complex tissue with a hierarchical-structure consisting of organic matrix, mineral hydroxyapatite, and water. Collagen comprises up to 90% of the organic matrix in the bone, and is vital for its mechanical behavior. To date, the morphological and mechanical responses of collagen fibrils in the bone matrix have been largely overlooked...

Introduction: Infections occurring in the wound as a consequence of the surgery represent the surgical field infections (SFI). Tibia diaphysis fractures are common due to its exposure to the external force. Clinical signs include: pain, swelling, lower leg deformity and skin changes. Tibia in the lower extremities has an eccentric position - from the front inner side it is covered only with the skin and from the back and the outer by muscle mass. The most common pathogens are: Staphylococcus aureus, Coagulase negative Staphylococcoc aureus or S...

Fractures are common traumatic injuries that mainly occur in the metaphyses of long bones such as the proximal humerus, distal radius, and proximal femur. However, most studies of fracture repair processes have focused on the diaphyseal region. In this study, we compared the bone repair processes of the metaphysis and the diaphysis of the mouse tibia. Bone apertures were formed in the tibial metaphysis and diaphysis. At indicated times after surgery, samples were collected, and the healing process was investigated using micro-computed tomography, as well as histological, immunohistochemical, and mRNA expression analyses...
