Öğe Clinical evaluation of ulnar nerve repair at wrist level(Springer-Verlag, 2004) Gurbuz, H; Aktas, S; Calpur, OUIntroduction. In this study, the results of ulnar nerve repair were analyzed. The relation between the functional outcome scores and clinical findings were investigated to find out whether any clinical finding could be predictive of the outcome. Materials and methods. Seventeen patients who underwent ulnar nerve repair formed the study group. Average follow-up lasted 45.5 months (range 39-48 months), and average age of the study group was 31.7 years (range 26-42 years). The same operative technique was applied to all patients by one of the authors (HG). Follow-up checks were done at 3, 6, and 12 months postoperatively. The patients who did not attend the last follow-up were excluded from the study group. The Seddon classification was used as the functional scoring system. Wound healing, Tinel sign, interosseous atrophy, atrophy of the first web space, clawing, and protective sensation were the clinical findings examined at the follow-ups. Wound healing was classified as either normal scar formation or hypertrophic scar-keloid (HsC) formation. Results. Good results in 4 and fair results in 13 were obtained according to the Seddon classification. Statistically, there was no difference between the clinical findings at the 3, 6, and 12 month follow-ups. Conclusion. Presence of HsC and clawing can be regarded as a predictive sign for fair results in nerve repairs.Öğe Full arthroscopic lateral retinacular release with hook knife and quadriceps pressure-pull test: long-term follow-up(Springer, 2005) Calpur, OU; Ozcan, M; Gurbuz, H; Turan, FThe most important causes of anterior knee pain include patellofemoral malalignment which causes patella - condyle contact anomalies at the patellofemoral joint, excessive patellar lateral pressure increase, trauma and overuse. In this article, besides presentation of late clinical results of 169 lateral retinacular release cases which were surgically treated between January 1995 and December 2002 with the help of a hook knife from the anterolateral portal due to lateral compression syndrome and patellar maltracking, we also described quadriceps tendon pressure-pull test which strongly indicates patellofemoral pain during physical examination of a patient with anterior knee pain. In addition to radiological patellofemoral imaging methods, we describe dynamic arthroscopic patellofemoral joint examination which is applied perarthroscopically to all of our surgically treated patients. We divided the patients into two groups: group 1 was the younger group with age 16 - 40 years; group 2 was the older group with age > 41 years. Preoperative mean Lysholm scores for group I was 67.6 and 98.6, postoperatively, whereas it was 62.3 preoperatively and 91.4 postoperatively in group 2. This improvement of Lysholm scores postoperatively was statistically significant for each of the two groups ( p= 0.001). For group 1 preoperative IKDC scores were A in 8 patients, B in 61 patients and C in 11 patients, whereas it was A in 78 patients and B in 2 patients postoperatively. For group 2 preoperative IKDC scores were A in 2 patients, B in 43 patients, C in 36 patients and D in 8 patients, whereas it was A in 78 patients and B in 11 patients. This improvement of IKDC scores postoperatively was also statistically significant for each of the two groups ( p= 0.001). Preoperative and postoperative congruens angles of all patients were also measured. Preoperative mean congruens angle was + 16.4 in group 1 while mean congruent angle was - 7.1 postoperatively. For group 2 preoperative mean congruens angle was + 18.7 preoperatively and - 6.9 postoperatively. This improvement was statistically significant for each of the two groups ( p= 0.001). The overall number of patellar lateral compression syndrome cases were 51 ( 24 in group 1, 27 in group 2), patellar lateralization cases were 64 ( 28 in group 1, 36 in group 2) and patellar subluxation cases were 54 ( 28 in group 1, 26 in group 2). At the evaluation of arthroscopic lateral patellar facet and lateral femoral condylar chondral pathologies, we statistically showed that patellar chondral pathologies were more severe than the femoral chondral pathologies ( p= 0.001). In our opinion, the severity of patellar lateral facet chondral lesions, although it has a thicker layer of cartilage, is due to distribution of load to a larger contact area of lateral femoral condyle [ 1, 2]. Statistically increasing severity of femoral ( Kendall's tau-b: 0.248, p= 0.001) and patellar chondral lesions ( Kendall's tau-b: 0.444, p= 0.0001) with age is compatible with our arthroscopic and clinical observations. The most important complication seen in our cases was fibrosis at the site of lateral release, seen in three patients. They were healed without any sequela with local corticosteroid injection into the fibrosis tissue. We did not see any hemarthrosis or haematoma as a complication.Öğe The role of acromioclavicular arthritis in impingement syndromes(Yonsei Univ College Medicine, 1998) Gurbuz, H; Unalan, H; Sarisaltik, H; Sekhavat, H; Candan, LThe role of acromioclavicular (A-C) arthritis in stage 2 and 3 impingement syndromes was investigated in this study. Twenty-seven patients with stage 2 and 3 impingement syndrome were evaluated both clinically and radiologically for the presence of A-C arthritis. Patients with A-C arthritis who were treated by conservative or surgical methods were rated before and after therapy according to the University of California at Los Angeles (UCLA) shoulder rating scale. The follow-up period ranged from 7 to 16 months with an average of 13 months. A-C arthritis was diagnosed in 21 of 27 patients (one grade 2 and 20 grade 3, according to Kellegren). Clinical and radiological evaluation of these 21 patients revealed A-C joint pain and a positive lidocaine injection test in all (100%), a positive horizontal adduction test in 20 (95.2%), decreased joint space in 18 (85.75%) and osteophytes in 11 (52.4%). Surgical treatment was considered for 12 A-C arthritis patients; and distal clavicle resection was performed in 11 of these cases. The average score measured by the UCLA rating scale increased from 13 to 28 in the group treated with surgery (satisfactory result), and from 10 to 13 in the group treated with conservative therapy (unsatisfactory result). The results of this study may be interpreted as demonstrating that A-C arthritis is a common etiologic factor in chronic impingement syndromes and its co-existance has a strategic importance in the choice of treatment method Surgical resection of the distal clavicle should be considered in the presence of this pathology since this technique provides excellent results in pain relief and appears to be superior to conservative therapy in these cases.Öğe Semi-empirical potentials for CuI(Natl Inst Optoelectronics, 2005) Dalgic, SS; Gurbuz, H; Caliskan, M; Ozgec, OWe have investigated the prospects for developing semi-empirical model potentials for use in the studies of structural properties of CuI with integral equation theories. The point of view adopted requires that only short range two atom and three atom interactions appear. A three-body potential of Tersoff has been tasted with the hypernetted chain integral equation by calculating the pair correlation function for CuI at 710 K. The two-body and three-body Kohen-Tully-Stillinger empirical interatomic potential has been applied. The structural results of liquid CuI have been compared with experiment and those obtained by rigid ion potentials.Öğe Tc-99m MIBI accumulation in myositis ossificans(Lippincott Williams & Wilkins, 1998) Sarikaya, A; Gurbuz, H; Cermik, TF; Pekindil, G; Demiral, H; Gumuser, FG; Erkmen, N[Abstract Not Available]
