Introduction: Accurate placement of implants is important to prevent a variety of complications including dislocation, decreased range of motion, and premature polyethylene wear in Total Hip Arthroplasty (THA). In addition, the difference in leg length after THA affects postoperative gait and low back pain, and the femoral offset is related to gait and abductor muscle function. The purpose of this study is to investigate whether implant placement, leg length difference, and hip offset are improved in supine THA using a 9-inch fluoroscopic HipGrid Drone. Materials and Methods: We retrospectively reviewed consecutive 80 patients who underwent primary unilateral primary THA through direct anterior approach at supine position: 40 THAs with the use of fluoroscopy and 9-inch Drone, and 40 THAs with the use of fluoroscopy alone. We compared the accuracy of component positioning, leg length discrepancy, and hip offset with or without Drone. Results: There was no significant difference in the inclination angle of the cup between the Drone group 37.9 degrees and the control group 39.0 degrees (p=0.175), but the variation from the target angle was more less in the Drone group compared with the control group (2.37 vs 3.82 degrees, p=0.013). With the use of the Drone, significantly more THAs had restoration of

Cutis Marmorata Telangiectatica Congenita is a very rare birth defect involving cutaneous blood vessels. Of unknown cause, uncertain pathophysiology, unclear epidemiology. Described as a localized, or generalized marbled skin appearance (cutis marmarota), in addition to the skin, it may involve any other body organs, with, or without a wide variety of associated congenital anomalies. Kato van Lohuizen described the first case in 1922. Since then, there have been less than 300 cases reported worldwide to date. We are adding one more case, and the first reported in Libya.

Bone grafts and Bone Void Fillers (BVF) have multiple applications in total joint reconstruction surgeries. However, despite their widespread use, they are contraindicated in Prosthetic Joint Infections (PJI). A BVF device is needed that will provide sustained antimicrobial protection to prevent biofilm formation and, ultimately, will resorb and be replaced by host bone. Currently, BVF are only used in noninfected cases in which powder antibiotics are added in hopes of preventing future infections. These BVF do not provide a sustained antibiotic level and, therefore, are not recommended for infected cases. A novel BVF, EP Granules with Tobramycin, was designed to fulfill the need for successful bone growth when infection is present. To create this unique and original BVF, an osteoconductive biomaterial was combined with clinically used degradable polymers, resulting in a composite ceramic polymer. Initial in-vitro elution studies followed by successful and animal in-vivo testing have demonstrated its effectiveness.

Introduction: Anterior Cruciate Ligament (ACL) reconstruction with hamstring graft is usually done for the surgical management of ACL tear. The post-operative outcome of ACLR is mainly dependant on graft healing its integration into the femoral and tibia tunnels. For the tendon to bone integration it can take up to several months post-surgery. Incorporation of graft into the bony tunnels plays an important role in post-operative outcome after ACL reconstruction surgery. In our study we have aimed to compare hamstring graft healing time post ACL reconstruction when graft was enveloped with periosteum as envelope. Material and Methods: 30 patients with isolated ACL tear were selected between age group of 18 to 40 years and were grouped randomly into 2 groups. In first group the hamstring graft was enveloped with the surrounding periosteum harvested were as second group the patients were not augmented with periosteal envelope. Post-operative rehabilitation remained similar in both the groups and MRI scan was done at 6 months, 9 months and 1 year post operatively to check for graft maturity.

Purpose: Progressive kyphoscoliosis is not of uncommon occurrence in patients with MPSs. Cranio-cervical junction in patients with MPSs are under the threat of three life threatening elements, namely GAGs accumulation, C1-2 instability, and progressive cervical vascular abnormalities. Material and Methods: Seven patients’ two girls and five boys with age range from 3 to 9 years presented with progressive kyphoscoliosis and atlanto-axial instability. Phenotype/genotype confirmed the diagnosis of Hurler syndrome and Hurler-Scheie syndrome. Though, spine deformities were to a certain extent similar in both types but with different age of onset. Results: Children with kyphoscoliosis of apical Cobb’s angle ranging between 60/65° were corrected up to 5° with normal sagittal spine balance. All showed an improvement in the neurological and functional status of Frankel motor scale (PreOp C / PostOp D) and Nurick scale (PreOp 2-3 / PostOp 2-3). The severity of myelopathy on the mJOA scale decreased (PreOp 12 / PostOp 10). Three children were excluded from surgical interventions because

Background: Either a combined approach or a transtrochanteric approach, performed with the patient in the lateral decubitus position, is used in Rotational Acetabular Osteotomy (RAO) to treat symptomatic hip dysplasia. Muscle strength after RAO using the transtrochanteric approach has been reported, but muscle strength after RAO using the combined approach has not been well studied. We aimed to investigate muscle strength and gait speed over a one-year follow-up period after RAO using the combined approach. Methods: Data from 124 patients who underwent RAO (129 hips) were analyzed retrospectively. Patients’ mean age was 44 years (14-64) and mean Body Mass Index (BMI) was 23 kg/m2 (16-36). Isometric hip flexion, abduction, and extension strengths and gait speed were measured before surgery and three months, six months, and one year after surgery. We assessed whether age and BMI were correlated with one-year postto pre-operative strength ratio. Results: Muscle strength had not changed significantly three months after surgery but had significantly improved at six months, exceeding pre-operative strength. One year after surgery, muscle strength of the treated hip exceeded that of the contralateral hip. Gait speed was significantly lower than pre-operative speed three months after surgery, recovered to pre-

Background: Nail dynamization is a controversial strategy used to treat delayed union in tibial shaft fractures. Reported union rates of nail dynamization varies within a wide range that goes from 19% to 100%. The purpose of this study was to perform a systematic review and a metaanalysis of the literature to explore post-dynamization union rates in cases of delayed union of tibial fractures following locked intramedullary nailing. Methods and Findings: This systematic review was conducted following the PRISMA (Preferred Reported Items for Systematic Reviews and Meta-Analyses) guidelines. We searched the Cochrane Database, PubMed, and the first 100 references of Google Scholar to June 2020. Inclusion criteria were as follows: English-language original research articles that included patients over 14 years of age with tibial shaft fractures treated with locked intramedullary nailing and posterior dynamization of static screws. Methodology quality was assessed using a modified version of Coleman’s score. We identified 14 studies that included 1198 fractures for full analysis. The mean age was 35.8 (range; 14-82 years) and the average follow-up period was 27 months (range; 3-100). Statically locked intramedullary nails were found in 922 (76.9%) fractures.

Background: Rhabdomyosarcoma (RMS) is the most common softttissue tumor in childhood. We aimed to study the prognostic factors of non-metastatic RMS in Tunisian paediatric patients. Methods: We reviewed data of paediatric patients (aged < 18 years), with histologically confirmed RMS treated in Salah Azaiez Institute for a non-metastatic RMS during 20 years. Prognostic factors were studied and survival data analysed. Results: 75 patients were included (42 males and 33 females). Embryonal RMS was the most common histologic type (72%) followed by alveolar (21%) and pleomorphic (1%). The most frequently affected sites were head and neck (43%) and genito-urinary (28%). 5-year OS and DFS were 50% and 26%, respectively. By univariate analysis, DFS was significantly correlated to chemotherapy, Radiotherapy (RT) and post-surgical RT with p=0.02, 0.003 and 0.01, respectively.
