Profound bone loss occurs following spinal cord injury (SCI) resulting in a high incidence of fractures. While likely caused in part by loss of weight-bearing, there is greater bone loss following SCI when compared to that observed in other disuse animal models. Patients with SCI have a protracted inflammatory response, with elevated circulating levels of pro-inflammatory markers. This chronic inflammation could compound the bone loss attributed to disuse and the loss of neural signaling. To assess this, we examined inflammatory markers and bone turnover regulators in osteocytes from rats with a moderate spinal contusion injury (SCI) and intact controls (CON)...

BACKGROUND: Bone fracture healing is dependent upon the rapid migration and engraftment of bone marrow (BM) progenitor and stem cells to the site of injury. Stromal cell-derived factor-1 plays a crucial role in recruiting BM cells expressing its receptor CXCR4. Recently, a CXCR4 antagonist, plerixafor, has been used to mobilize BM cells into the blood in efforts to enhance cell migration to sites of injury presumably improving healing. In this study, we employed zirconium-89 (89 Zr)-oxine-labeled BM cells imaged with positron emission tomography (PET)/computed tomography (CT) to visualize and quantitate BM cell trafficking following acute bone injury and to investigate the effect of plerixafor on BM cell homing...

The treatment of open distal tibia fractures remains challenging, particularly when the fracture involves severe soft tissue damage and segmental bone loss. We present the case of a 33-year-old woman who sustained an open distal tibia fracture type 43-A3.3, with segmental bone loss, and a closed bifocal fibular fracture. The fractures were initially fixed with a temporary external fixator. The open distal tibial fracture underwent an intramedullary nailing on day six post-trauma, while the segmental bone loss was refilled with a temporary cement spacer, in order to create a biologic chamber, according to the technique by Masquelet et al...

The medial meniscus (MM) posterior root has an important role in the maintenance of knee kinematics and articular cartilage. Although transtibial pullout repair of the MM posterior root tear (MMPRT) has become the gold standard, it is associated with several suturing difficulties. The present technical note describes a simple fixation technique using two simple stiches under an expected initial tension. After the degree of knee flexion (20°) and an expected tension (30 N) are checked, tibial fixation is performed using a bioabsorbable interference screw with a spring tensioner...

We conducted a study to evaluate the reliability of the medial hemi-soleus muscle flap for wound coverage of infected open fracture of distal third of tibia. Wound coverage of exposed lower third tibia and ankle region remains a difficult task. Muscle flaps are preferred for infected wounds especially where there are exposed bone, joint and/or tendons. Soleus muscle is a good option for local reconstruction. Soleus being the prime ankle plantar flexor and stabilizer of the ankle in ambulation cannot be sacrificed without significant morbidity...

Salter-Harris type I fractures of the distal tibia are commonly seen in paediatrics and management of such fractures follows an algorithm established in the literature. Despite this, osteonecrosis of the distal tibia can subsequently develop. Osteonecrosis or avascular necrosis is cell death that occurs secondary to trauma, metabolic disturbances, sickle cell disease, or medication side effect. It most frequently affects the femur, talus, or humerus, and rarely the tibia. Radiographs and MRI are pivotal in making a timely diagnosis in order to minimize patient discomfort...

Distal tibia fractures are complex injuries with high complication rates. Limited soft tissue, poor vascularity and complexity of fracture pattern impose limitations for traditional plating techniques. Better understanding of fracture patterns using 3D-CT reconstruction, optimum pre-op planning and availability of anatomical locking plates have certainly improved the outcome in these fractures. We report the functional and radiological outcome in 12 patients of complex tibial pilon fractures, who were treated on the basis of the novel column concept...

INTRODUCTION: Tibial pilon fractures are often treated with initial external fixation followed by delayed definitive fixation. It has been postulated that the external fixator pin site may correlate with infection risk. The purpose of this study was to determine whether external fixator pin-site distance from definitive implants impacts the risk of deep infection in pilon fractures. MATERIALS AND METHODS: A retrospective cohort study was completed at a single level 1 trauma center...

Background: Tibial tuberosity osteotomy (TTO) is a versatile procedure commonly used to treat patellar instability as well as to unload cartilage lesions. TTO with concomitant distalization (TTO-d) may be performed in patients with patella alta to stabilize the patella by helping it to engage in the trochlea earlier during flexion. Purpose: To identify and compare perioperative complications in patients who underwent TTO and those who underwent TTO-d and to analyze risk factors associated with these complications...

Adult-acquired flatfoot deformity is a progressive flattening of the arch of the foot that results from posterior tibial tendon insufficiency with a predilection for middle-aged women. A lateralized force vector associated with hindfoot valgus in adult-acquired flatfoot produces lateral ankle pain due to impingement at the lateral hindfoot, which can even lead to stress fractures of the distal fibula. Here, we present the rare case of a 73-year-old woman who presented with stress fractures of the bilateral taluses and unilateral distal fibula accompanied by severe adult-acquired flatfoot deformities...

BACKGROUND: The effect of bone mineral density (BMD) on outcomes from total ankle arthroplasty (TAA) has not been studied. BMD can be estimated by measuring Hounsfield units (HU) on standard computed tomography (CT), which is frequently performed prior to TAA. We aimed to identify whether tibial and talar HU measured from preoperative CT scans were associated with periprosthetic fracture or revision risk in patients undergoing TAA. METHODS: A prospectively collected database was used to retrospectively screen all patients undergoing primary TAA...
