The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia...

CASE REPORT: A 4-month-old female intact American Pit Bull Terrier was presented for right pelvic limb lameness 1 day after the dog had been hit by an all-terrain vehicle. Orthogonal radiographs of the right stifle revealed a Salter-Harris type IV fracture through the proximal tibial physis extending caudodistally through the proximal tibial metaphysis. The distal tibia was markedly displaced cranially, laterally and proximally, resulting in complete overriding of the fracture segments...

BACKGROUND: The treatment of limb threatening trauma on the distal tibia or hindfoot often results in posttraumatic osteoarthritis requiring tibiotalocalcaneal (TTC) arthrodesis. The purpose of this study was to present a case series of patients undergoing various techniques of joint fusion after bone reconstruction and deformity correction as a salvage procedure. The study should help trauma surgeons making decisions in limb salvage and deformity correction in complex lower leg and foot injuries by presenting options and treatment strategies...

BACKGROUND: miR-124-3p has been reported to be involved in the pathogenesis of many diseases by modulating a variety of signaling pathways. In this study, we aimed to understand the impact of miR-124-3p expression level on the fracture healing in the patients of metaphyseal fracture of distal tibia, who received minimal invasive percutaneous plate osteosynthesis. METHODS: We firstly collected 195 patients of metaphyseal fracture of distal tibia, and the genotype of rs531564 was determined: GG (n=124) and GC+CC (n=71)...

INTRODUCTION: Tibial shaft fractures comprise a large portion of operatively treated long bone fractures, and present with the highest rate of open injuries. Intramedullary fixation has become the standard of care for both open and closed injuries. The rates of short term complications and hospital length of stay for open and closed fractures treated with intramedullary fixation is not fully known. Previous series on tibia fractures were performed at high volume centers, and data were not generalizable, further they did not report on length of stay and the impact of preoperative variables on infections, complications and reoperation...

Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder associated with unilateral anterolateral bowing with subsequent fracture and nonunion. In infancy, physiologic bowing of the lower leg can be confused with pathologic tibial dysplasia in NF1. Little is known about the bone physiology of the tibiae prior to fracture or predictors of fracture. The aim of this study was to characterize bone quality of bowed tibiae prior to fracture in NF1 using quantitative ultrasound (QUS). Bone quality was assessed on both tibiae (the non-bowed and bowed tibiae) using QUS to measure speed of sound (SOS) at the mid-shaft in 23 individuals with NF1...

Complex tibia fractures are often provisionally stabilized with external fixation prior to definitive fracture fixation. Bicortical defects, such as those left after removal of a fixator pin, can decrease the torsional strength of long bone. Evaluating the effect of subsequent plate fixation in close proximity to a defect on the torsional strength of the tibia is the purpose of this study. Eight groups of 5 fourth-generation left composite tibias were tested to failure in torsion. The experimental plated groups consisted of bicortical defects at 3 cm, 2 cm, and 1 cm distal to the plate end, with 1 plated group without a defect...

INTRODUCTION: Infected nonunion of long bones is a chronic and debilitating disorder. It is more difficult to deal with when the implant used for internal fixation itself becomes a potential media for infection because of bacterial adhesion and biofilm formation. Traditionally, it is managed by two-stage procedure for controlling the infection first and then treating the nonunion. This study has been undertaken to explore antibiotic cement coated nailing as single stage treatment modality for treating infection and achieving stability at the same time...

Introduction: Intramedullary nailing has been used frequently for the treatment of tibial diaphyseal fractures. Chronic anterior knee pain has been considered the most frequent post-operative complication of this technique. We investigated the relationship between anterior knee pain and position of nail tip in proximal tibia. Methods: 103 patients were selected among patients who underwent interlocking nailing in our institution. Patients with other factors that might cause anterior knee pain were excluded...

INTRODUCTION: Previously, it was found that fracture healing is impaired by blunt chest trauma and an additional soft-tissue trauma. The mechanisms leading to this disturbance are largely unknown. Here, we investigated the effect of thoracic and soft-tissue trauma on blood flow of the injured lower leg and on tissue differentiation and callus formation during fracture healing. MATERIALS AND METHODS: Male Wistar rats received either a mid-shaft fracture of the tibia alone (group A), an additional chest trauma (group B), or additional chest and soft-tissue traumas (group C)...

Tanshinol is a major water-soluble active component of Salvia miltiorrhiza. In this study, we aimed to investigate whether tanshinol has potential therapeutic effects against glucocorticoid-induced osteoporosis and glucocorticoid-induced myopathy. Ninety-six female Sprague-Dawley rats were randomly assigned to five groups: a control group, a model group, and three model groups treated with 25 or 50 mg/kg of tanshinol, or calcitriol. All model groups received prednisone acetate for 90 days to induce glucocorticoid-induced osteoporosis...

In 1879, Paul Segond described an avulsion fracture (now known as a Segond fracture) at the anterolateral proximal tibia with the presence of a fibrous band at the location of this fracture. Although references to this ligament were occasionally made in the anatomy literature after Segond's discovery, it was not until 2012 that Vincent et al named this ligament what we know it as today, the anterolateral ligament (ALL) of the knee. The ALL originates near the lateral epicondyle of the distal femur and inserts on the proximal tibia near Gerdy's tubercle...

Acute limb compartment syndrome (ALCS) is a serious complication of traumatic injury. Although ALCS can occur in any limb, it most commonly occurs following injury to the lower leg, particularly in fractures of the tibia. Practitioners should recognise and treat ALCS as early as possible to prevent the development of further, potentially serious, complications. Most of the literature recommends that patients at risk of ALCS should be carefully monitored, with a focus on pain as the main symptom. However, patients in the intensive care unit (ICU) who are unconscious or sedated may be unable to report pain or are unreliable in doing so, therefore it is necessary to consider alternative assessments for ALCS...

OBJECTIVES: External fixators are the traditional fixation method of choice for contaminated open fractures. However, patient acceptance is low due to the high profile and therefore physical burden of the constructs. An externalised locking compression plate is a low profile alternative. However, the biomechanical differences have not been assessed. The objective of this study was to evaluate the axial and torsional stiffness of the externalised titanium locking compression plate (ET-LCP), the externalised stainless steel locking compression plate (ESS-LCP) and the unilateral external fixator (UEF)...

Macrophages are important phagocytosing and cytokine producing cells with effects on fracture healing. We used clodronate-containing liposomes to reduce the number of macrophages, in order to study their role in the early phases of cancellous bone healing. Holes were drilled bilaterally into the cancellous bone of the proximal metaphysis of the tibia of 60 mice. A screw was inserted in the hole in the right tibia. The day of surgery was day 0. Clodronate-containing liposomes were injected intraperitoneally as a single injection either day -4 or -1 (before surgery) or day 1 or 3 (after surgery)...

The aim of the present study was to analyze the mechanism by which nerve growth factor (NGF) promotes callus formation in mice with tibial fracture. NGF transgenic homozygotic mice and NGF wild homozygotic mice were selected to construct non-stabilized fracture model of tibia. The mice were sacrificed on days 7, 14 and 21, respectively, and each group had a sample with 8 mice at each point in time. X-ray radiography and safranin fast green were used to observe fracture healing and in situ hybridization was used to examine the NGF mRNA expression of tibia at each phase of fracture healing...
