Based on biomechanical anatomical studies, double-bundle reconstruction of the anterior cruciate ligament (ACL) was introduced to achieve better stability in the knee, particularly in respect of rotatory loads. An in vivo, computer-assisted, double-bundle (DB) ACL reconstruction is superior to a single-bundle (SB) ACL reconstruction at reducing rotatory,(More)
PURPOSE To evaluate the role of percutaneous stenting in the treatment of renal arterial lesions after failure of balloon angioplasty. METHODS Two hundred ten patients (139 males; mean age 67.7 +/- 9.9 years, range 27 to 87) had 259 balloon-expandable stents (165 Palmaz and 94 Renal Bridge stents) implanted in 244 renal artery stenoses (171 ostial and 73(More)
UNLABELLED Iatrogenic vascular injuries are uncommon during the course of proximal femur surgical procedures. We report the case of an 85-year-old female presenting with an intertrochanteric fracture, treated by anterograde (cephalocondylic) intramedullary nailing (Stryker gamma 3 nail) and complicated by a superficial femoral artery laceration at the level(More)
PURPOSE Perilunate dislocations and transscaphoid perilunate fracture dislocations are associated with a high incidence of posttraumatic arthritis. According to the current literature, at medium-term follow-up, radiological signs of arthritis do not correlate with functional scores. The aim of this study was to evaluate patient hand function and the(More)
PURPOSE The purpose of this study is to evaluate the clinical and radiological outcomes of hemiepiphysiodesis with a single medial staple of the proximal tibia in idiopathic genu valgum angular correction. METHODS A retrospective review was performed identifying nine adolescents (18 knees) treated for idiopathic adolescent genu valgum by means of a(More)
The Pins and Rubber Traction System (PRTS) can be used to treat proximal interphalangeal intra-articular fractures. Our experience is that outcomes are not always excellent and that many patients have reduced joint function or residual deformities. The aim of this study was to evaluate the reasons behind the poorer outcomes of some of the patients treated(More)
Adolescent idiopathic scoliosis is a 3D spine deformity that worsens during the whole growth. The treatments available are bracing during the whole growth to avoid progression of the deformity and surgical fusion of the spine at skeletal maturity for the most severe curves. Recent advances in flexible spinal implants have given rise to new expectations in(More)
The primary goal of curve correction in neuromuscular patients is to restore coronal and sagittal trunk balance, including the pelvis, to maximize sitting balance. For several years, it has been a common practice to inject polymeric cement into osteoporotic bone through specially designed, perforated pedicle screws in an effort to enhance screw stability.(More)
We have evaluated the effect of bracing in scoliosis on coronal alignment in a cohort of patients. Current literature has not described the specific effect of bracing on the 3D shape of the scoliotic curves. The purpose of this study was to analyze the variability of the 3D effect of bracing on idiopathic scoliosis. The spines of 30 patients with adolescent(More)
One of the major revolutions in the field of adolescent idiopathic scoliosis (AIS) during the past 10 years is the development of 3D imaging devices in standing position, such as EOS (EOS Imaging). 3D vision of the spine is new; we need to be humble and learn how it may help in the management of AIS. But we now have access to the transverse plane deformity.(More)
