The core aim of this study was to investigate zinc (Zn)and and strontium (ZnSr)-containing brushite-forming β-tricalcium phosphate (TCP) cements for their effects on proliferation differentiation osteoblastic-like cells (MC3T3-E1 cell line) as well in vivo behaviour trabecular bone cylindrical defects a pilot study.In vitro maturation responses MC3T3-E1 were studied at the cellular molecular levels.The Zn-and Sr-containing brushite found stimulate pre-osteoblastic osteoblastic...
Given the high prevalence of patients with hip deformities and no ongoing dysfunction, understanding anatomic factors predicting symptomatic state is critical. One such variable how spinopelvic parameters (SPPs) may interplay factors.SPPs femoral- acetabular-specific predict which will become symptomatic. The purpose was to determine characteristics specific cutoffs were associated symptom development these relate each other.Cohort study (Diagnosis); Level evidence, 2.548 participants...
In this study, a three-dimensional finite element (FE) model based on the specific anatomy of patient presenting femoroacetabular impingement 'cam'-type is developed. The FE meshes structures interest are obtained from arthrographic magnetic resonance images. All soft tissues considered linear elastic and isotropic, bones were assumed rigid. A compression femur acetabular cavity as well flexural movements internal rotations applied. Stresses contact pressures evaluated in patient-specific...
Background: Knowledge of the vascular supply femoral head is crucial for hip-preserving surgical procedures. The critical area reshaping cam deformity at retinacular vessel penetration, an with ill-defined topographic anatomy. We performed a cadaver study extension lateral retinaculum near head-neck junction, distribution arterial foramina, and initial intracapital course these vessels. Methods: In 16 fresh proximal parts femur without deformities, deep branch medial circumflex artery was...
Abstract Literature on the reconstruction of proximal femur in skeletally immature patients with use an epiphyseal transplant is scarce and variable results depending indication. We report successful outcomes using a modified vascularized fibular 4‐year‐old boy oncologic lesion. discuss advantages supplementing standard graft periosteal tissue. The (VFET) effective option epiphysis patients, owing to advantage restoring both joint function growth potential single surgical operation. 1...
Abstract Several microsurgical techniques have been described for the treatment of osteonecrosis talus (ONT). Recently reported in children, vascularized periosteal grafts showed promising revascularizing properties. We report a novel technique using pedicled graft from first metatarsal bone to treat steroid‐induced early Ficat‐Arlet stage III ONT an 11‐year‐old boy. The patient presented initial favorable clinical and radiological results which were maintained at 34 months during last...
The Bernese periacetabular osteotomy (PAO) is a widely used procedure to reorient dysplastic acetabulum resulting from developmental dysplasia of the hip, retroversion, protrusio, or some deformities with traumatic etiology. Throughout execution, lateral femoral cutaneous nerve (LFCN) as well obturator, femoral, and sciatic nerves can be injured. Injury 1 3 major devastating event for patient followed by an ill-defined period hope recovery fear lifelong disability. Surgical experience...
Background The modified Dunn procedure, which is based on the development of an extended retinacular flap containing blood supply for femoral head, allows anatomic reestablishment in patients with moderate to severe slipped capital epiphysis (SCFE). Some controversy exists regarding short-term midterm risk avascular necrosis (AVN) and other complications resulting from surgical technique. Questions/purposes (1) What percentage treated during procedure SCFE a (slip angle 30° 60°) or slip...
Hemiarthroplasty has been associated with inferior and unpredictable outcomes when used in the treatment of complex proximal humeral fractures elderly patients. In this age-group, reverse shoulder arthroplasty is gaining popularity due to promising results presented recent evidence. Our aim analyze cases treated by arthroplasty, regarding functional complications.Thirty-five from 33 patients mean age 73.5 (65-81) years were for humerus. These followed a 38.3 months (24-68) analyzed clinical...
The purpose of this study was to report (1) a different but specific pattern impingement in hips involved with valgus slipped capital femoral epiphysis (valgus SCFE) and (2) the results surgical treatment using intracapsular realignment techniques.Case series.Multiple academic centers.Six patients 8 referred for alignment proximal SCFE).Intracapsular osteotomy combined periacetabular if needed.The clinical radiographical pathophysiology motion.Eight 6 were treated subcapital (5 hips) or neck...
