The current study conducted to detect the genetic diversity between four genetic groups of Kurdish local chicken using RAPD-PCR technique. Ten random markers used to amplified DNA were selected for genotyping the four lines. One hundred twenty four polymorphic bands were amplified, the bands size ranged between (2500 and 100 bp). The primer (OPA-05, OPA-18) produced maximum number of polymorphic bands, while primers named (OPA-16) produced minimum number of polymorphic bands. The (WNFS) genetic group showed the highest number of amplified fragments (55) for both male and female (30), (25) respectively. While (BBN) genetic group showed the lowest number of amplified fragments (20) for both male and female (7), (13) respectively. According to the results obtained from the current study, it can be conclude that the four genetic groups differ genetically. Moreover the results will help the breeders to study new selection strategies between the four genetic groups.
Both ACDF and ACCF using FVFG provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stay and shorter operative times.
Background:.The Thoracolumbar Injury Classification and Severity Score (TLICS) was developed to improve injury classification and guide surgical decision making, yet validation remains necessary. This study evaluates the functional ,clinical and radiological outcome of patients with thoracolumbar spine trauma (TLST) treated according to the TLICS. Aim of the work:To validate the efficacy of Thoracolumbar injury classification and severity score (TLICS) in orthopaedic emergency department at sohag university hospitals. Patients and methods:The TLICS was prospectively applied to a consecutive series of patients (30 cases) treated for TLST between October 2016 and October 2017. Patients with a TLICS score more than 4 points were surgically treated, whereas patients with a TLICS score of less than 4 points were conservatively managed.Those with a score of equal 4 ,group were managed conservatively and the other were operated.The primary outcome was the American Spinal Injury Association Impairment Scale (AIS) (1) . Results:The decision taken according to TLICS either conservative if the final score <4 or operative if >4. Conservative treatment in the form of rest and dorsolumbosacral brace .Operative in form of posterior fixation with or without decompression .Transpedicular fixation and decompression was needed in 10 cases (33.33%) because they were suffering from neurological insult.The mean age was 34years.There were a marked improvement in angle of kyphosis , vertebral height loss and Oswestry disability index .No patient had neurological worsening during the follow-up.Conclusion:.Thoracolumnar injury and severity score is valid and safe for management of thoracolumbar fractures and has good reliability.PDF created with pdfFactory Pro trial version www.pdffactory.com
Introduction The optimal treatment of humeral shaft fractures continues to be debated. In the current investigation, we sought to determine the clinical and radiographic outcomes following the plate fixation of humeral shaft fractures utilizing the modified posterior approach. Materials and methods A retrospective review identified a consecutive series of 30 humeral shaft fractures (OTA20-A, 10-B, or 0-C) treated with plate fixation via a posterior (14 patients), ormodified posterior approach (16 patients) between 2016 and 2017 by a single surgeon. Demographics, operative reports, clinical follow-up, and preoperative radiographs were reviewed. Postoperative radiographs were assessed for angular deformity and time to union. Range of motion and strength testing were also reviewed. Results A total of 30 humeral shaft fractures were reviewed with a mean clinical follow-up of 4 months. The mean time to union was13.1 weeks and there3 patients developed radial nerve palsies in posterior approach group and one case in modified posterior approach postoperatively. Conclusionboth approaches could be used in the management of humeral diaphyseal middle or distal third fractures, And the modified posterior approach confirmed by our results minimizes the complication rate, allow early return of full range of elbow motion and full triceps muscle power and facilitates early return to normal activities of the patient with excellent functional out comes .
Introduction Atlantoaxial rotatory fixation (AARF) is also known as rotatory subluxation, rotatory displacement, rotary deformity, rotational subluxation, and is characterized by incomplete dislocation of the inferior atlantal and superior axial articular facets.1 AARF in combination with odontoid fracture is an extremely rare injury.2–6 Atlantoaxial injuries can be classified according to Fielding 1 or White and Panjabi7 classification. The management of this combination is a matter of debate. 1,8,9 Material and Methods We present a case of a 78 years old woman who sustained a fall on the ground from a couch directly on her forehead, resulting in atlantoaxial dislocation with type II odontoid fracture accompanied with left sided hemiparesis ASIA type C. Results After failure of closed reduction, the treatment plane was to achieve reduction under anesthesia and C1–2 fusion, but again reduction was not possible. Occipitocervical fusion to C3 was done to have better stability in osteoporotic bone. Successful reduction was achieved during rod reduction from the occiput to C2 pedicle screw and C3 lateral mass screw. Cervical collar was advised for 3 months, and good fusion and improvement of the neurological status to ASIA type D was achieved after 6 month. Conclusion AARF with Odontoid Fracture is a rare combination and reduction may be impossible. Occipitocervical fusion is a good option in such case as C1–2 reduction is a prerequisite for transarticular screw. C2 pedicle screw offers good purchase even in osteoporotic bone which enabled reduction after rod repositioning. References Fielding JW, Hawkins RJ. Atlanto-axial rotatory fixation.
