INTRODUCTION: Femoral neck fractures are uncommon injuries in children, but the high incidence of long-term complications makes it important clinical entity. Early surgical treatment to achieve optimal results and to avoid a high rate of complications is widely advised. The purpose of this study was to retrospectively analyze the outcome of 8 children who sustained a femoral neck fracture. PATIENTS AND METHODS: The patients (6 boys and 2 girls with an average age of 9...

With 1% of all skeletal fractures patellar fractures are rare. The majority of cases are caused by a direct trauma to the flexed knee. The diagnosis is made via the injury mechanism as well as the physical and radiological findings. In conventional x‑ray imaging the extent of injury often is underrated, which mostly leads to the necessity of a computed tomography (CT) scan. The aim of the treatment is the reconstruction of the extensor mechanism and the anatomical reconstruction of the articular surface...

Background  Arthroscopic total wrist arthrodesis is a procedure with minimal violation of extensor compartments and less scar formation, compared with open wrist arthrodesis. In this paper, we would like to present our experience with a modified surgical technique for arthroscopic total wrist arthrodesis. Description of Technique  After an arthroscopic cartilage removal through radiocarpal and midcarpal portals, the operation is continued under fluoroscopic control. In this technique, four wires are inserted separately in four various directions (as described in the paper), followed by insertion of self-tapping cannulated screw, under fluoroscopic control...

Radius and ulna fractures are the most common long bone fractures in children and adolescents. The majority of these injuries involve the distal metaphyseal portion of the radius associated or not to physeal plate injuries. Because of the high remodelling potential of the distal radius in growing children most injuries heal without complication after closed reduction and immobilization in a long arm cast. Nonunions of closed distal radius fracture are an extremely rare occurrence especially in paediatric population...

HYPOTHESIS: Fixation of a 3-part radial head fracture with cannulated compression screws will show equivalent stiffness to a locking plate under axial load. Debate exists regarding the management of Mason type III fractures, with many believing that open reduction and internal fixation provides advantages over other options. By virtue of their subarticular placement, screw fixation is less likely to cause impingement compared with plate fixation, which can result in loss of rotation and requirement for hardware removal...

Valgus slipped capital femoral epiphysis (SCFE) is very infrequent, and it is characterized by a superolateral displacement of the epiphysis on the metaphysis. To date, less than 100 cases of valgus SCFE have been described in the literature. Bilaterality of valgus SCFE is extremely rare, and it presents management challenges to the treating orthopedic surgeons. Herein, we report the case of an 11-year-old Saudi Arabian girl presented to clinic with a one-year history of bilateral hip pain and limping. Past medical history was negative for endocrinopathies, hemoglobinopathies, bone disorders, trauma or radiation therapy to the pelvis...

Management of proximal pole scaphoid nonunion remains a challenging problem. Multiple surgical techniques have been described, although no treatment has proven superior. Recent studies have questioned the need for vascularized bone grafting, even in in the setting of avascular proximal poles. We present a relatively simple technique of intramedullary autogeneous cancellous bone grafting that does not disturb the intact cortical shell of the nonunion, which has so far provided gratifying clinical results.

Introduction: This paper assesses whether treating patients with fibrous dysplasia of proximal femur by internal fixation with correction of the deformity, if present, without grafting is enough or not. Methods: This study is a retrospective study using patient's medical records, including analysis of 19 patients with fibrous dysplasia of proximal femur treated by internal fixation only and followed up between 2000 and 2017 for at least 2 years. Epidemiologic data, clinical manifestations, radiologic and histologic investigations, surgery, functional outcomes, and complications in these patients were analyzed...

BACKGROUND: Screw fixation is a typical technique for the isolated subtalar joint. However, no consensus has been reached on how to select the most suitable insertion position and direction. This study aims to find the ideal screw insertion and then explore its influence on the clinical efficacy of subtalar fusion by analyzing the effects of different cannulated screw insertions on the stress distribution, anti-rotary strength, and anti-inversion/eversion strength of the subtalar joint...

BACKGROUND: Anterior odontoid screw fixation (AOSF) is an osteosynthetic technique used for fixation of type 2 and rostral type 3 odontoid fractures. Compared to other treatment modalities, it provides immediate stability, preservation of the majority of the remaining C1-2 motion and an achieved union rate of 80-100%. AOSF requires a stable and reduced odontoid to allow for placement of guide wire and cannulated screw. Image guidance with neuro-navigation or intraoperative fluoroscopy are used for accurate placement of instrumentation...

Background: Standard fluoroscopic navigation and stereotactic computed tomography-guided lumbar pedicle screw instrumentation traditionally relied on the placement of Kirshner wires (K-wires) to ensure accurate screw placement. The use of K-wires, however, is associated with a risk of morbidity due to potential ventral displacement into the retroperitoneum. We report our experience using a computer image-guided, wireless method for pedicle screw placement. We hypothesize that minimally invasive, wireless pedicle screw placement is as accurate and safe as the traditional technique using K-wires while decreasing operative time and avoiding potential complications associated with K-wires...

BACKGROUND: Internal fixation is often used to treat pathologic proximal femur fractures. However, nonunion and/or tumor progression may lead to hardware failure. In such cases, endoprosthetic replacement may be considered. The purpose of this study is to analyze the outcome of patients undergoing conversion to an endoprosthetic replacement following failed fixation of a pathological proximal femur fracture. METHODS: We identified 26 patients who underwent conversion hip arthroplasty for salvage of failed fixation of a pathologic proximal femur fracture between 2000 and 2016...

Intramedullary nailing is the most popular and widely used method for treating tibial shaft fractures. Intramedullary nailing involves minimal surgical dissection, allowing preservation of blood supply by not disrupting the soft tissue around the fracture. The procedure is performed with the following steps: (1) the patient is positioned supine on the radiolucent operating table with a bump under the ipsilateral hip; (2) a 4 to 6-cm longitudinal incision is made 2 to 4 cm directly proximal to the superior pole of the patella; (3) the quadriceps tendon is sharply incised at its midline and split longitudinally; (4) a cannula device with a blunt trocar and protective sleeve is inserted into the knee joint between the articular surface of the patella and the trochlea of the distal part of the femur, after which a second pin can be inserted through the cannula device and into the distal part of the femur to stabilize the cannula and keep it from backing out; (5) a 3...

Introduction: Intra-articular glenoid fracture is rare injury and conservatively treated significantly displaced intra-articular glenoid fractures have been found to have poor functional outcomes, and thus most are now treated with open reduction and internal fixation as this allows accurate reduction of the articular surface under direct vision. [8]. Here, we describe the case of an Ideberg Type 3 fracture treated with open reduction and internal fixation by cannulated cancellous screw through coracoid process in which it is used as a reduction tool and as a guide...

Patellar fractures account for approximately 1% of all human body fractures. This study aimed to compare the surgical outcomes of open reduction and closed reduction for patellar fractures. This retrospective study included 62 patients (63 cases) who underwent surgical treatment of patellar fractures from 2008 to 2013. Of the 63 cases, open and closed reductions were performed in 42 and 21 cases, respectively. Plain radiography was used to assess fracture healing. Comminuted patellar fracture was the most common fracture type in both groups...
