Anterior tibial tuberosity fracture avulsion is an uncommon injury. A concomitant patellar rupture is even more scarcely encountered. We report the case of a 14-year-old male patient who suffered bilateral anterior tuberosity fractures with concomitant bilateral complete patellar tendon rupture. Adolescence, athletic activity, and high BMI may have contributed to this concomitant bilateral injury. Both lesions were treated in a one-stage repair surgery, performing an open reduction and internal fixation of the tibial tuberosity with a cannulated cortical screw and a primary tendon suture following the Krakow technique. To the authors’ knowledge, no other cases of bilateral presentation of both lesions have been reported so far in the literature.

Osteosarcoma is the most common primary malignant tumour of bone. The oncologic surgery of a proximal femur osteosarcoma affecting the hip joint can be very challenging. We present an 8-year-old boy with a 5-month history of right hip pain. Radiographs and magnetic resonance imaging (MRI) showed a lytic lesion of the proximal femur extending 13 cm to the diaphysis. Histological evaluation was consistent with high-grade osteoblastic osteosarcoma. After completing chemotherapy we performed an extra-articular resection of the hip. Reconstruction was accomplished by reimplanting the acetabulum after irradiation and modular proximal femur megaprosthesis. Endoprosthetic reconstruction following proximal femur resection is a good treatment alternative achieving good postoperative function. Extra-articular resection of the hip using a periacetabular osteotomy technique enabled us to achieve wide margins and leave an intact posterior column to optimize acetabular reconstruction stability. Extracorporeal irradiation and reimplantation is a valuable treatment option in a situation such as this where allograft geometric fit is a priority. We conclude that an extra-articular resection of the hip, followed by reconstruction with an extracorporeally irradiated acetabulum and a proximal femur modular megaprosthesis, is a useful combined treatment option for malignant lesions involving the hip joint, especially in paediatric patients.

Fracture malalignment and nonunion are not infrequent after treating subtrochanteric fractures with intramedullary nails. The use of a cerclage wire with a minimally invasive approach to aid and maintain reduction in certain subtrochanteric fracture patterns can be an effective surgical strategy to improve outcome. It allows the surgeon to obtain and maintain an anatomic reduction with more bone contact, which will aid in fracture consolidation. This has the added advantage of optimizing the greater trochanteric starting point. It minimizes malreductions of the proximal femoral fragment, and, we believe, that its rational use with a minimally invasive technique is a key factor in achieving good results.

Most published reports of a floating clavicle consist of a dislocation of both ends of the clavicle and are associated with a high-energy injury. We report a 71 year old patient with a fracture of the medial end of the clavicle with anterior sternoclavicular dislocation and a nondisplaced fracture of the lateral end of the same clavicle distal to the insertion of coracoclavicular ligaments due to a low velocity fall.

Background: Tendon transfers are often used in foot and ankle surgery. Different fixation devices and techniques have been described. The most recently developed ones are bone anchors and interference screws. Materials and Methods: A biomechanical study was designed to compare tendon transfer fixation, using Corkscrew bone anchors 5 × 15.5 mm and Biointerference screws (8 × 23 mm). Fifteen fresh cadaver specimens underwent both fixation techniques for split anterior tibial tendon transfer at the cuboid bone. All the specimens underwent standardized X-rays in order to evaluate mineral bone density using a standardized measurement system. All were tested until maximal load to failure. Results: The ultimate load to failure of the tendon secured to the cuboid using anchors was 103 N (SD, 52), compared with 150 N (SD, 68) for tendons secured to the bone with interference screws ( p = 0.003). No difference was found between the techniques that could be related to bone density. Conclusion: Interference screws provided greater strength than bone anchors. Clinical Relevance: This study demonstrated increased strength in securing bone to tendon in vitro for SPLATT tendon transfer with interference screws as compared to suture anchors.
