BACKGROUND: Fractures in the posterior aspect of the medial malleolus form an important subset of ankle fractures and the indications for fixation include involvement of > 25% of the articular surface or an articular step off by > 2mm. Several approaches have been described but there has been no recent study on the direct medial approach. METHODS: Five fresh frozen cadaveric ankles were dissected using the direct medial approach. A longitudinal incision of 10cm was centered directly over the medial malleolus and deepened straight down to the bone...

Many imaging modalities have been described to diagnose and monitor osteoporosis (OP), osteoarthritis and inflammatory rheumatic diseases. Over the last ten years, High Resolution peripheral Quantitative Computerized Tomography (HR-pQCT) was shown to be a precise and non invasive technique to study bone and joint diseases in clinical research. It allows the study of both cortical and trabecular bone microarchitecture at the distal tibia and radius, and further applications have been developed such as the study of mechanical properties by the finite element analysis...

Chaput tubercle fracture occurs at the antero-lateral position of the distal tibia in adult as a counterpart of adolescent Tillaux fracture. It is a case of adult male which presented to us with onset of acute pain, swelling and restricted movements of ankle after a road side accident. A clinical diagnosis of Chaput tubercle fracture was established after a CT-scan. The displaced fracture was managed by open reduction and internal fixation by screw. At the end of follow up, the foot and ankle ability score measured...

BACKGROUND: Medial malleolar fractures are frequent, and their treatment is familiar to the orthopedic surgeon. Lag screw fixation using partially threaded screws remains the standard treatment method for medial malleolar fractures. However, the literature lacks a defined method for selecting lag screw length, relying more so on the empiric choice of the surgeon. AIM: The aim of this study is to help define the ideal lag screw length for medial melleolar fracture fixation...

BACKGROUND: The Segond fracture was classically described as an avulsion fracture of the anterolateral capsule of the knee. Recently, some authors have attributed its pathogenesis to the "anterolateral ligament" (ALL). Biomechanical studies that have attempted to reproduce this fracture in vitro have reported conflicting findings. PURPOSE: To determine the anatomic characteristics of the Segond fracture on plain radiographs and magnetic resonance imaging (MRI), to compare this location with the location of the ALL described in prior radiographic and anatomic publications, and to determine the fracture's attachments to the soft tissue anterolateral structures of the knee...

We report a rare congenital limb defect with combined features of both fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO) and Fuhrmann's syndromes. A female newborn infant, born to nonconsanguineous Egyptian parents, presented with isolated abnormalities of the lower limbs comprising bilateral shortening and anterior bowing of the lower limbs at the distal third of the tibia and split foot. Radiographic examination revealed complete absence of both fibulae, anterolateral bowing and shortening of the tibia, bowing of the femora, and absence of several metatarsal and phalangeal bones...

Disturbances in bone blood flow have been shown to have deleterious effects on bone properties yet there remain many unanswered questions about skeletal perfusion in health and disease, partially due to the complexity of measurement methodologies. The goal of this study was use fluorescent microspheres in rats to assess regional bone perfusion by adapting mouse-specific fluorescent microsphere protocol. Ten fifteen-week old Sprague Dawley rats were injected with fluorescent microspheres either via cardiac injection (n = 5) or via tail vein injection (n = 5)...

Bony defects in recurrent shoulder instability can lead to the failure of soft tissue reconstruction. Many techniques have been developed to address glenoid defects in an attempt to prevent recurrent instability. However, the high complication rates with the Latarjet procedure have led surgeons to identify other sources of bone graft, including the distal tibia allograft (DTA). The DTA appears to be a suitable option for anterior glenoid reconstruction, highlighting the importance of reconstructing all bony defects and the versatility and efficacy of allograft bone blocks...

Stress fractures are a frequent cause of lower extremity pain in athletes, and especially in runners. Plain imaging has a low sensitivity. Magnetic resonance imaging (MRI) or bone scan scintigraphy is the criterion standard, but expensive. We present the case of a young female distance runner with left shin pain. Plain radiography was unremarkable. Ultrasound showed focal hyperechoic elevation of the periosteum with irregularity over the distal tibia and increased flow on Doppler. These findings were consistent with a distal tibia stress fracture and confirmed by MRI...

Minimally invasive percutaneous plate osteosynthesis was developed on the concept that preservation of the soft tissue envelope during surgical management of distal tibial fractures is of paramount importance. We report on our early experience using this technique over a 1-year period with 14 such injuries that were treated by a locking compression plate via minimally invasive surgery. The surgical reduction was excellent in most of the cases and all fractures healed uneventfully. One superficial infection and a wound slough were the only complications recorded...

INTRODUCTION: Despite advances in our understanding of anterior cruciate ligament (ACL) anatomy and function, the change in position of the ACL during tibial rotation is not well understood. The purpose of this study was to quantify and compare the movements of the anteromedial (AM) and posterolateral (PL) bundles of the ACL during 15° of medial and lateral rotation (with & without a shear force). MATERIALS & METHODS: Cadaveric knees (12 male/12 female) were dissected and mounted at 90° of knee flexion...

Background and purpose - Hexapod ring fixators such as the Taylor Spatial Frame (TSF) have shown good outcomes. However, there have only been a few studies comparing the use of TSF with various etiologies of the deformity. We compared the use of TSF in congenital and acquired deformities in children. Patients and methods - We reviewed 213 lower extremity reconstructive procedures with the TSF in 192 patients who were operated between October 2000 and October 2015. 128 procedures (67 proximal tibiae, 51 distal femora, and 10 distal tibiae) in 117 children (median age 14 (4-18) years; 59 girls) fulfilled the inclusion criteria...

OBJECTIVES: Clinical practice has shifted from therapeutic anticoagulation of any lower extremity venous thromboembolism (VTE) to only thromboses with risk of proximal extension or embolization - clinically important VTE (CIVTE). Isolated operative fractures of the tibia and distally are associated with low-to-intermediate VTE risk and there is wide variability in the choice to anticoagulate as well as anticoagulant. We sought to evaluate the role for chemoprophylaxis of VTE and CIVTE in these injuries by meta-analysis of Level I evidence...

Adamantinoma is a rare, low-grade, malignant bone tumor. It frequently occurs in the tibia but rarely arise in the distal end of the fibula. This study reported a case of adamantinoma arising in the distal end of the fibula, resulting in good prognosis. A 38-year old female felt left ankle pain, and was suspected as having a bone tumor at the distal end of the fibula by X-ray. She was diagnosed as the classical adamantinoma of the fibula by open biopsy. En bloc wide resection of the tumor, primary arthrodesis of the ankle was performed...

BACKGROUND: Allograft reconstruction of oncologic resections involving the tibia can have unpredictable results. Prior studies have reported a high rate of complications and a long recovery period involving prolonged bracing, repeated procedures and extended periods of antibiotics. METHODS: The case details of 30 tibial allografts (12 adults, 18 children; 20 intercalary, 7 hemicortical, 3 other) were reviewed retrospectively. Based on factors including function, pain, healing and infection, clinical outcomes were stratified into three categories: excellent, moderate, and poor...

BACKGROUND: The bone morphologies of intact knees were measured and compared between Chinese and Caucasian populations. However, to assess if distinct designs of implants are necessary for the Chinese population owing to different morphologies and sizes, the knee measurements after osteotomy performed in total knee arthroplasty were evaluated. METHODS: Thirty-seven Caucasian and 50 Chinese patients' knees were examined using computed tomography scans. Mimics were applied to reconstruct 3-dimensional bone models...
