To our knowledge, proximal tibiofibular joint instability has never been reported in a patient with a total knee arthroplasty (TKA). We present the case of a patient with anterolateral proximal tibiofibular joint instability associated with a complex primary TKA. In 2010, a male patient of 47 years was referred for TKA after posttraumatic osteoarthritis. The patient's history includes a fracture of the left lateral tibial plateau in 2008 and removal of osteosynthesis material in 2009. TKA with a lateral metal augment and intramedullary stem was performed in 2010...

The anterolateral ligament (ALL) of the knee has gained attention recently for its potential role in rotational stability of the knee, especially in association with anterior cruciate ligament (ACL) injuries. Anatomic studies have characterized the ALL as it runs in an anteroinferior and oblique direction from the lateral distal femur to the anterolateral proximal tibia, although the prevalence and variance of this ligament are not well understood. Magnetic resonance imaging and ultrasound have identified the ligament and linked it with the classically described Segond fracture...

PURPOSE: Appropriate fixation method for the posterior malleolar fractures (PMF) according to the fracture size is still not clear. Aim of this study was to evaluate the outcomes of the different fixation methods used for fixation of PMF by finite element analysis (FEA) and to compare the effect of fixation constructs on the size of the fracture computationally. MATERIALS AND METHODS: Three dimensional model of the tibia was reconstructed from computed tomography (CT) images...

PURPOSE: The role of the proximal tibiofibular joint (PTFJ) in tibial plateau fractures is unknown. The purpose of this study was to assess, with finite-element (FE) calculations, differences in interfragmentary movement (IFM) in a split fracture of lateral tibial plateau, with and without intact fibula. It was hypothesized that an intact fibula could positively contribute to the mechanical stabilization of surgically reduced lateral tibial plateau fractures. METHODS: A split fracture of the lateral tibial plateau was recreated in an FE model of a human tibia...

Traumatic bone defects of the distal femur and proximal tibia present treatment challenges for the orthopaedic traumatologist. In addition to bone loss, significant soft tissue compromise and cartilage defects leave the patient and surgeon with few reconstructive options for proper long-term joint function. These injuries are often complicated by delayed healing, nonunion, malunion, infection, and poor subjective patient outcomes. There are a variety of clinical problems associated with the treatment of periarticular fractures about the knee...

Several plate systems for high tibial osteotomy (HTO) have been developed to stabilize the opening wedge of an osteotomized tibia. Among them, the TomoFix system, having a quasi-straight and T-shaped design, has been widely adopted in the literature. However, this system is implemented by inserting a lag (i.e., cortical) screw through the proximal combi-hole, to deform the plate and pull the distal tibia toward the plate. This process potentially induces plate springback and creates an elastic preload on the osteotomized tibia, especially at the lateral hinge of the distracted wedge...

BACKGROUND: Although relatively rare, non-unions and mal-unions of tibial plateau fractures present significant challenges for the orthopedic surgeon. With careful pre-operative planning, tibial plateau mal-union or non-union revision surgery with intra-articular and varus opening osteotomies can provides good functional results when performed early (within 1 year) after primary surgical procedure. QUESTIONS/PURPOSES: We present our treatment algorithm for approaching and treating non-union or mal-union of tibial plateau fractures...

OBJECTIVES: The goal of this study is to compare the fatigue strength of a locking intramedullary nail (LN) construct with a double locking plate (DLP) construct in comminuted proximal extra-articular tibia fractures. METHODS: Eight pairs of fresh frozen cadaveric tibias with low bone mineral density [age: 80 ± 7 (SD) years, T-score: -2.3 ± 1.2] were used. One tibia from each pair was fixed with LN, whereas the contralateral side was fixed with DLP for complex extra-articular multifragmentary metaphyseal fractures (simulating OTA 41-A3...

Background and purpose - Fracture healing involves different inflammatory cells, some of which are not part of the traditional bone field, such as B-cells and cytotoxic T-cells. We wanted to characterize bone healing by flow cytometry using 15 different inflammatory cell markers in a mouse model of metaphyseal injury, and incidentally discovered a previously unknown general skeletal reaction to trauma. Material and methods - A bent needle was inserted and twisted to traumatize the cancellous bone in the proximal tibia of C57/Bl6 female mice...

Pregnancy, lactation, and weaning result in dramatic changes in maternal calcium metabolism. In particular, the increased calcium demand during lactation causes a substantial degree of maternal bone loss. This reproductive bone loss has been suggested to be largely reversible, as multiple clinical studies have found that parity and lactation history have no adverse effect on postmenopausal fracture risk. However, the precise effects of pregnancy, lactation, and post-weaning recovery on maternal bone structure are not well understood...

BACKGROUND: Reports showing high recurrence rates for intralesional curettage and bone grafting have made the current treatment principle for fibrous dysplasia controversial. This study aimed to report the postoperative clinical outcomes from three minimally invasive surgical strategies we use for monostotic fibrous dysplasia (MFD). PATIENTS AND METHODS: Twelve patients with MFD presenting with no pathologic fracture or deformity and treated with one of three surgical strategies-plain open biopsy, plain alpha-tricalcium phosphate (ATP) reconstruction, and prophylactic bridge plating-were included...

OBJECTIVES: In the context of pediatric sports injuries, the epiphyseal and apophyseal knee fractures represent rather peculiar lesions. The most frequently involved anatomical area is the knee. The peculiar function of the physis and the need to preserve their integrity, makes choosing what treatment methods to employ very important. Objective of this study is to assess the kind and the effectiveness of the most suitable treatment in the apophyseal and epiphyseal knee lesions occurring in the adolescents...

INTRODUCTION: Latest advances made in joint replacement implants allows reconstruction of entire limbs. These special prostheses or megaprostheses were originally designed for the treatment of severe oncological bone loss. Nowadays, however, the indications and applications of these devices are expanding to other orthopaedic and trauma clinical conditions. Since 2008 we have implanted 152 megaprostheses in non-oncological conditions: 87 were implanted for post-traumatic failures aseptic/septic (represented by complex non-unions and critical size bone defects); 26 total femur, 52 distal femur and 9 proximal tibia...

OBJECTIVE: To explore the mechanism of the "killer turn", which is reported to be a reason for postoperative residual laxity after transtibial posterior cruciate ligament (PCL) reconstruction, in a low bone mineral density (BMD) condition. METHODS: A total of 80 skeletally mature female New Zealand white rabbits were included for biomechanical evaluation after transtibial PCL reconstructions. The subjects were equally divided into low BMD (n = 40) and control groups (n = 40)...

Most tibial eminence fractures are avulsion fractures of the anterior cruciate ligament (ACL) from its tibial insertion. This study describes a new arthroscopic technique using an additional proximal superomedial portal to visualise the tibial eminence fracture and to fix the fracture with the EndoButton to avoid the risk of fragment breakage. The proximal superomedial portal enables fracture reduction without damage to the intermeniscal ligament. Fixation with the EndoButton is strong enough to allow early rehabilitation with vigorous exercise...

INTRODUCTION: Closed reduction and cast application is still regarded as first line treatment for pediatric tibial fractures. Over the past few decades, management of pediatric tibial fractures has shifted more towards operative intervention because of quicker recovery, shorter rehabilitation period, less immobilization, lack of stiffness of adjoining joints, and less psychological impact to the children. Flexible intramedullary nails not only fulfill the above advantage but also maintain alignment and rotation...

Peroneal nerve palsy is common. The hallmark clinical manifestation of peroneal nerve palsy is drop foot. In the drop foot condition, the ankle cannot flex, and the foot does not clear the ground during the swing phase of gait. Spontaneous nerve repair can yield complete or incomplete resolution of drop foot. Some patients with incomplete resolution are left with a drop hallux condition, in which the ankle can dorsiflex, but the hallux remains unable to dorsiflex. This has not been thoroughly discussed in the past, regarding surgical repair...

BACKGROUND: The human body has an extensive capacity to regenerate bone tissue after trauma. However large defects such as long bone fractures of the lower limbs cannot be restored without intervention and often lead to nonunion. Therefore, the aim of the present study was to assess the pool and biological functions of human mesenchymal stromal cells (hMSCs) isolated from different bone marrow locations of the lower limbs and to identify novel strategies to prime the cells prior to their use in bone fracture healing...

Persons with spinal cord injury (SCI) undergo immediate unloading of the skeleton and, as a result, have severe bone loss below the level of lesion associated with increased risk of long-bone fractures. The pattern of bone loss in individuals with SCI differs from other forms of secondary osteoporosis because the skeleton above the level of lesion remains unaffected, while marked bone loss occurs in the regions of neurological impairment. Striking demineralization of the trabecular epiphyses of the distal femur (supracondylar) and proximal tibia occurs, with the knee region being highly vulnerable to fracture because many accidents occur while sitting in a wheelchair, making the knee region the first point of contact to any applied force...
