ABSTRACT Purpose: The purpose of the study was to compare results anterior cervical discectomy and fusion (ACDF) using standalone cages versus with plating for multilevel disc disease a 2-year follow-up. Background: ACDF is commonly performed procedure in cases neural compression caused by osteophytes or material. Some spine surgeons have reported unsatisfactory outcomes rates secondary high rate cage subsidence pseudoarthrosis. Internal fixation plate has been developed as an adjunct...

Segmental mandibular resection represents a challenge to maxillofacial surgeons in terms of accurate contouring reconstruction plates, restoration symmetry and maintaining condylar position the glenoid fossae.We propose CAD/CAM technique for fabricating patient-specific templates symmetrically prebend guide osteotomies reposition process proximal edentulous segment its preoperative position. We operated on two patients using this new technique.The custom-made showed excellent passive fit...

Background: Many children with developmental dislocation of the hip especially in underdeveloped countries reach walking age and still remain undiagnosed, which can be detrimental to their growth development. Because lack medical services often encountered these regions, it would attractive find a cheap effective treatment. Our work evaluated results treatment by closed reduction or without adductor tenotomy prospective study. Methods: We included 20 patients this study 29 affected hips (15...

Unstable trochanteric fractures are challenging with a high rate of implant failure and re-operation. Cephalomedullary nails proved to be rational management choice for these injuries, yet other options have not been well assessed. The aim this study was compare the use DHS stabilizing plate (TSP) proximal femoral locked (PFLP) in unstable pertrochanteric fractures.This randomized controlled trial (RCT) included 40 patients (22 males, 18 females) (AO/OTA 31A2.2/A2.3). were into group 1...

Integrated cage and screw designs were introduced for anterior cervical discectomy fusion (ACDF) allegedly are superior to plating due their minimal profile.A descriptive study was designed as a prospective case series of 25 patients (30 operated discs) with disc disease treated zero-profile cage, followed up an average 16 months (range 12 -18 months). Functional assessment done the Neck Disability Index (NDI) Visual analog scale (VAS) scores arm neck pain. Furthermore, Nurick's...

Introduction : Lag screw cut-out is a serious complication of dynamic hip fixation trochanteric fractures. The lag position has been acknowledged as one the important factors affecting cut-out. We propose modification Tip Apex Distance (TAD) and hypothesise that it could improve reliability predicting screws in these injuries. Materials Methods A retrospective study was conducted for fracture entries period from Jan 2018 to July 2022. hundred nine patients were suitable final analysis....

Bilateral inverted third molar impaction is an extremely rare condition. We reported the case of a 50-year-old female patient with bilateral and impacted maxillary molars. Both were asymptomatic pathology free clinically radiographically. Surgical extraction these molars inaccessible positions requires aggressive bone removal on tuberosity bilaterally. Moreover, it contains high risk displacement into sinus. Conservative management was choice, patient's agreement, left in situ. Key...
