Which Implant Is Better for Treating Reverse Obliquity Fractures of the Proximal Femur: A Standard or Long Nail?

WOS: 000322879800010PubMed ID: 23564362Reverse obliquity fractures of the proximal femur have biomechanical characteristics distinct from other intertrochanteric fractures and high implant failure rate when treated with sliding hip screws. Intramedullary hip nailing for these fractures reportedly has less potential for cut-out of the lag screw because of their loadbearing capacity when compared with extramedullary implants. However, it is unclear whether nail length influences healing. We compared standard and long types of intramedullary hip nails in terms of (1) reoperation (fixation failure), (2) 1-year mortality rate, (3) function and mobility, and (4) union rate. We conducted a pilot prospective randomized controlled trial comparing standard versus long (a parts per thousand yen 34 cm) intramedullary hip nails for reverse obliquity fractures of the proximal femur from January 2009 to December 2009. There were 15 patients with standard nails and 18 with long nails. Mean age was 79 years (range, 67-95 years). We determined 1-year mortality rates, reoperation rates, Parker-Palmer mobility and Harris hip scores, and radiographic findings (fracture union, blade cut-out, tip-apex distance, implant failure). Minimum followup was 12 months (mean, 14 months; range, 12-20 months). We found no difference in reoperation rates between groups. Two patients (both from the long-nail group) underwent revision surgery because of implant failure in one and deep infection in the other. There was no difference between the standard- and long-nail groups in mortality rate (17% versus 18%), Parker-Palmer mobility score (five versus six), Harris hip score (74 versus 79), union rate (100% in both groups), blade cut-out (zero versus one), and tip-apex distance (22 versus 24 mm). Our preliminary data suggest reverse obliquity fractures of the trochanteric region of the femur can be treated with either standard or long intramedullary nails

Surgical treatment of displaced radial neck fractures in children with metaizeau technique: Late-term results Metaizeau technique : Late term results

Aim: in this study, we aimed to analyze the functional and radiological outcomes of displaced radial neck fractures in children treated with the Metaizeau technique . Material and Methods: This was a retrospective study, and data were collected prospectively. Thirty-eight patients with grade III and grade IV radial neck fractures according to the classification of Judet et al were managed surgically by Metaizeau technique. All patients were surgically treated with percutaneous k-wire leverage reduction and retrograde transphyseal k-wire fixation. The functional results were evaluated using the Metaizeau functional scoring system. Clinical evaluation and results were performed using the Mayo elbow performance score (MEPS), ROM of the elbow (flexion, extension) and forearm (supination, pronation) was measured with a goniometer. Complications were also evaluated. Results: The average follow-up time was 64.9 months (28 -120 months), there were no patients with nonunion, avascular necrosis, infection, posterior interosseous nerve (PIN) injury, heterotopic ossification or radioulnar synostosis. There were 31 (88.5 %) excellent or good results and 4 (11.5 %) fair results according to the Metaizeau classification. The final X-rays showed fracture healing in all patients. No patient developed complications. Discussion: Intramedullary pinning, as described by Metaizeau, is a reliable and reproducible surgical method to treat radial neck fractures in children, which provides excellent or good results and has a low risk of complications
