This biomechanical study was conducted to compare fixation stability of the proximal fragments and their mechanical characteristics in femur models unstable basicervical IT fractures fixed by cephalomedullary nailing using 3 different types femoral head fixation.A total 36 composite femurs corresponding osteoporotic human bone were used. These specimens with Gamma (hip screw type; group 1) 12, U-blade (screw-blade hybrid 2) nail antirotation-II (helical blade 3) respectively, an fracture...
Perioperative blood management is an important issue in the treatment of elderly patients at increased risk postoperative complications. Accordingly, tranexamic acid (TXA) widely administered to reduce loss and transfusion requirements. In this case-control study, effect topical TXA on outcomes with femoral neck fractures after hemiarthroplasty was evaluated.This study enrolled (age ≥ 70 years) who underwent cementless bipolar for between January 2015 2017. The group comprised 72 received...
To the best of our knowledge, there have been no reports on points at which denervated multifidus and erector spinae muscles become reinnervated after pedicle screw fixation posterior fusion in patients with lumbar degenerative diseases. Our study was designed to confirm reinnervation paraspinal following alleviation patients' lower back pain (LBP). In this prospective study, we enrolled 67 who had undergone fusion. The surgery alleviated their leg pain, but complained LBP L3-5 level 3...
Abstract The objective of this retrospective study was to investigate the surgical outcomes AO/OTA 31 A1-3 trochanteric fractures treated with new-generation Gamma3 nail U-Blade (RC) lag screw and analyze risk factors related fixation failure. A total 318 consecutive patients who underwent cephalomedullary nailing using for hip between September 2015 June 2018 were enrolled. average age 80 years most (69%) women. mean follow-up 12.2 months a minimum 6 months. 309 (97.2%) showed bony union...
Antiplatelet medication has been frequently performed in elderly patients with hip fracture, because of comorbidities. This observational cohort study was to evaluate the effect continuous perioperative antiplatelet on outcomes after cephalomedullary nailing (CMN) a proximal femur fracture.One hundred and sixty-two consecutive aged ≥70 years undergoing CMN for fracture between January 2015 2017 were recruited. Of 162 patients, 47 (study group) taking antiplatelets preoperatively due...
Syndesmotic impingement syndrome has been described to explain persistent lateral or anterolateral ankle pain. This condition is thought often result from a rotational injury. study aimed identify the type of syndesmotic tissue according arthroscopic and histologic findings analyze its association with talar cartilage lesions.
Category: Ankle, Ankle Arthritis Introduction/Purpose: The Takakura staging system has been used for the stratification in ankle osteoarthritis(OA). Patient’s OA stage is determined by visual examination on status of talar and distal tibia anteroposterior radiograph. Clinical decisions about whether to treat conservatively or with operation such as supra-malleolar osteotomy arthroplasty may depend this grading system. However, not completely reproducible between examiners it makes a debating...
Distal femur fractures in elderly patients with osteoporosis are complicated because poor bone quality makes screw purchase and fixation less secure, presenting many clinical challenges to the orthopedic surgeon.Minimally invasive locked plating using an angularly stable locking compression plate has become integral tool for achieving secure osteoporotic distal improved biomechanical performance.On other hand, complications, such as implant failure periplate fracture, have still...
Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Due to the increase in life expectancy, frequency of elderly patients with moderate severe hallux valgus deformity is expected increase. The aim this study was evaluate clinical and radiological efficacy bilateral simultaneous correction aged 70s compare results those middle age. Methods: From August 2014 July 2017, 92 women (184 feet) patients, who underwent surgery (proximal chevron metatarsal osteotomy, Akin distal soft tissue...
