Humeral periprosthetic fractures are a challenging problem and their occurrence has increased, particularly over the last decade. The role of cerclage wires or cables in these fractures includes revisions with longer stems, and augmentation of a plate osteosynthesis in which the stem does not allow additional screw placement or structural bone grafts as supplementary fixation. ⋯ Placing a cerclage wire or cable around the fractured fragments offers a simple and safe procedure to avoid radial nerve injury or palsy in the treatment of complex humeral shaft fractures. This new technique is a simple and safe procedure to place a cerclage wire or cable around the humeral shaft.

Comparative Study
Reliable anatomical landmarks for minimizing leg-length discrepancy during hip arthroplasty using the lateral transgluteal approach for femoral neck fracture.
The purpose of this study was to describe our experience of a preoperative templating technique, and to investigate the most reliable anatomical reference to minimize leg length discrepancy (LLD) during hip arthroplasty using the lateral transgluteal approach for femoral neck fractures. We hypothesized that the medial fracture tip and greater trochanter would be viable alternative anatomical References METHODS: A total of 156 hip arthroplasty cases were enrolled in the present study (103 women, 114 hemiarthroplasties, 42 total hip arthroplasties). Preoperative acetate overlay templating was conducted based on pelvic anteroposterior radiographs. Three different anatomical references were used to determine the bony resection level, including the uppermost point of the lesser trochanter, uppermost point of the greater trochanter, and medial fracture tip. The accuracy of preoperative templating and the reliability of each anatomical reference for minimizing LLD were assessed. ⋯ The results of this study suggest that the use of the lesser trochanter as an anatomical reference to determine the level of femoral neck osteotomy should be discouraged, and that the medial fracture tip and greater trochanter may be better alternatives when using the lateral transgluteal approach.

Intact knee extensor mechanism is required for the normal function of the lower extremity. Patellar tendon rupture is a relatively rare injury with peak age incidence around 40 years and usually occurs midsubstance. The occurrence of pure patellar tendon rupture without bony avulsion is an extremely rare injury in the pediatric population with few cases reported in the literature with limited information regarding frequency, complications, and outcomes in children. However, due to increased participation in sports and high-energy recreational activities during childhood, the frequency of such injuries has progressively increased. ⋯ Patellar tendon rupture is rare in the pediatric population and represents 7% of pediatric patients who sustained acute traumatic injury of the knee extensor mechanism. Ruptures may occur midsubstance, or from proximal or distal insertions. High riding patella is the hallmark diagnostic sign for such injury. Although rare, it is considered a serious injury that necessitates early diagnosis and surgical intervention. Functional range of motion was obtained in all patients with different modalities of treatment.

Femoral shaft fractures are among the most severe injuries of the skeleton. They are associated with high morbidity and mortality. The most appropriate treatment depending on the type of fracture and location level should be chosen. ⋯ The obtained results between both nail materials (stainless steel and titanium alloy) show a higher mobility when using titanium nails, which produce a higher rate of strains at the fracture site, amplitude of micromotions and bigger global movements compared to stainless-steel nails. Steel nails provide stiffer osteosyntheses than the titanium nails. In conclusion, anterograde locked nail is particularly useful in the treatment of a wide range of supracondylar fractures with proximal extension into the femoral diaphysis.
