Purpose: The purpose of this study was to evaluate the effect of Desktop scanning protocol on accuracy of guided implant placement in completely edentulous patients.Methodology: Twenty four completely edentulous patients were selected for implant placement. Complete dentures were made for all the patients. Radioopaque markers were added to the dentures to be used as a radiographic stent. A Cone beam CT scan was then made for each patient while wearing the radiographic stent. The patients were then randomly divided into 2 equal groups. In the first group, a CBCT scan was made for the radiographic stent. In the second group, desktop scanning was made for the radiographic stent while being seated on the patient's cast and another scan for the patient's cast. After implant insertion, CBCT scan was made for each patient while wearing the radiographic stent. Superimposition of CBCT scans pre and post implant insertion was made. Deviations between planned and placed implant were measured in the lateral apical, lateral coronal and angular aspects.Results: Non statistically significant difference between radiographic and desktop scanning on implant deviation was observed. Conclusion:within limitation of this study, effect of both scanning protocols on the lateral apical, lateral coronal and angular deviations of placed implants is comparable.

Background. Knee arthroplasty surgeries are in ever-increasing demand. With unicompartmental knee arthroplasty (UKA), patients may benefit from a higher range of flexion and a better Knee Society Score (KSS). Aim. In this study, we compared the short-term clinical outcomes of total knee arthroplasty (TKA) and UKA using the patient-specific templating (PST) technique. Methods. Two groups of 20 knees each were divided into UKA and TKA groups depending on the Oxford criteria of UKA. Only patients with medial compartmental osteoarthritis were included. KSS, functional knee score (FKS), and ROF were assessed preoperatively and at 6 months postoperatively. Results. The TKA group has shown a significant improvement compared to the UKA group in KSS (MD = 39.35 vs. 31.2, respectively, p = 0.003 ). Both TKA and UKA have shown no significant difference concerning both the FKS (MD = 32 and 31.75, respectively, p = 0.926 ) and ROF (MD = 10.25 and 7.25, respectively, p = 0.072 ). Discussion. The higher improvement of KSS in the TKA group can be attributed to the fact that patients in the TKA had significantly worse KSS preoperatively. Also, the small improvement in ROF in the UKA group might be related to their wider preoperative ROF. Conclusion. Preoperatively, the TKA group had lower KSS and ROF compared to UKA. The improvement of KSS from preoperative to postoperative was more significant in TKA. However, the TKA group has shown less range of flexion postoperatively.

Background: Subacromial impingement syndrome is a common disorder about the shoulder. Patients presented by shoulder pain and impaired activity of daily living. Patients can be treated conservatively and if failed surgical intervention is indicated which could be open or arthroscopically with variable results. Aim and objective: This study was conducted to compare effectiveness and benefits between arthroscopic and open subacromial decompression in treatment of subacromial impingement syndrome. Method: The study was approved by the local ethics committee, and a written consent was obtained for each subject, and included 60 patients; 30 patients was treated by arthroscopic subacromial decompression and the other 30 were treated by open surgery. Patients were followed for a period of one year. Results: Functional outcome was assessed using the American shoulder and elbow surgeons' score. The arthroscopic group (A) had significant high score in first three months after operation than the open group (B). And after 6 months the significance between the two groups decreased till one year after operation at which there was no significance. Conclusion: Our results revealed that arthroscopic subacromial decompression for subacromial impingement syndrome were effective and safe than open surgery.

The goal of this study is to evaluate surgical treatment outcomes of fracture shaft humerus by using intramedullary interlocking nail. Fifteen patients (ages ranged from 51 to 70 with an average age of 64.20 ± 6.338 years, (10 males and 5 females) with shaft humeral fractures from Beni-Suef University and General hospitals during the period from December 2012 to June 2014. The selected participants were treated with intramedullary interlocking nail. Patients were followed up for a mean of 9 (range 6-12) months. The mean length of hospital stay was 3 (range 1-5) days. All the fractures united radiographically after a mean of 14 (range, 12-20) weeks. Conclusion: That the majority of humeral shaft fractures can be treated safely and effectively by non-operative methods. However, for the subset of patients requiring surgical treatment, intramedullary nailing provides predictable means of achieving fracture stabilization and ultimate healing. Poor outcome in intramedullary interlocking nailing is attributable to rotator cuff tear and shoulder impingement and lack of expertise of surgeon.
