    ABSTRACT: One of the functions of fetuin-A is the restriction of formation and expansion ofextraosseous hydroxyapatite crystals. TIhe exact correlation of fetuin-A with bone mineral density (BMD) has not been clearly elucidated yet. In this study, we aimed to assess the relationship between BMD and fetuin-A in postmenopausal women. Fifty postmenopausal women (25 with osteoporosis, 25 healthy controls) were included in the study. All participants were comparable for age and body mass index. None of the osteoporotic patients had received any medical treatment for osteoporosis. Serum fetuin-A levels were measured by ELISA method. BMD scores of the groups were statistically significant (P < 0.001). Serum fetuin-A levels of the osteoporosis group were significantly lower compared to the control group (P = 0.009). Additionally, there was there was a mild to moderate positive correlation between fetuin-A and lumbar (r = 0.381, P = 0.06) and femoral (r = 0.143, P = 0.50) BMD in the osteoporotic group, though it did not reach statistical significance. Decreased fetuin-A levels in women with postmenopausal osteoporosis suggest that fetuin-A may have a role in the development of osteoporosis. Further studies are required to define the exact role of fetuin-A in bone metabolism.

    ABSTRACT: The aim of the study was to investigate effect of I/R injury on bone tissue and protective role of hyperbaric oxygen precondition (HBO-PC) and ozone precondition (O(3)-PC) on I/R injury by using biochemical analysis. Thirty-two rats were included in study. The animals were divided into four equal groups: sham operation, I/R, I/R+HBO and I/R+O(3). One session of 60 min, 3 ATA, 3-4 L/min, 100% oxygenation was defined as one dose of HBO. First dose of HBO was administrated 72 h before ischemia. Subsequent, one-dose of HBO administrated per 12 hours until ischemia time (total seven doses); 0.7 mg/kg ozone/oxygen mixture intraperitoneally was defined as one dose of ozone. First dose of O(3) was administered 72 h before ischemia (total four doses). I/R model was induced in anesthetized rats by unilateral (right) femoral artery clipping for 2 h followed by 22 h of reperfusion. The right tibia and were harvested. Tissue was assayed for levels of malondialdehyde (MDA) and protein carbonyl (PCO), activities of superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). MDA and PCO levels were increased in I/R group. SOD activity was increased; GSH-Px activity was decreased in I/R group. MDA and PCO levels were decreased, SOD and GSH-Px activities were increased in both HBO+I/R and O(3)+I/R groups. It has been shown that levels of MDA and PCO in bone were increased followed by 2 h of ischemia and 22 h of reperfusion period. Ozone-PC and HBO-PC has protective effect against skeletal bone I/R injury by decreasing levels of MDA and PCO, increasing activities of SOD and GSH-Px in rats.

    ABSTRACT: Aim: The aim of this study was to evaluate the open surgical technique and clinical outcomes of the bankart repair for glenohumeral instability. Material and Method: Open Bancard repair by suture anchors tecnique was performed to 92 patients having glenohumeral instability. The patients who had completed the rehabilitation lasting 6 months have been included in this study. Twenty-four of the 92 patients were excluded because of various reasons like inadequate follow up etc. Sixty-eighr patients who have completed the six weeks physiotherapy programme made the study group. All patients were male with a mean-age 24.55 at the time of surgery. The mean age of the first dislocation was 19.5. and the mean number of the dislocation was 20.7. The mean follow-up time was 30.7 (6-52) month. Results: There was no recurrence in any patients. The mean Rowe score of the cases were 95.5 (80-100). By means of the Rowe score, excellent results in 60 patients (88.2 %) and good results in 8 (11.8 %) patients were obtained. We faced no failure as there was no recurrence in any patients.The mean external rotation decrease was 7.46 0. Conclusion: The aim at the treatment of the glenohumeral instability is that the instabilitation is prevented without limiting the motion of the glenohumeral joint. From this point of view, Bankart technique is one of the most appropriate technique.

    ABSTRACT: Acromioclavicular joint dislocation is the most common pathology of the shoulder region. Frequently it is seen in sporting activities especially in contact sports. But most of them, which can be treated by non surgical and rehabilitation methods, are type 1 and type 2 injuries. By these treatment methods generally proper healing can be accomplished. Type 4,5,6 acute acromioclavicular injuries are seen less often and are treated surgically. But in the treatment of type 3 injuries a consensus has not been established. Recently, an inclination towards conservative treatment is seen in the beginning. But surgical treatment is proposed in the symptomatic sports players. In the surgical treatments, while making a solid repairment, the aim is to provide a pain free joint with range of motions similar to the preoperative values. Several surgical methods are described for this purpose. In this review, the subject has been summarized in the light of the relevant literature.

    ABSTRACT: We evaluated the results of arthroscopically assisted circular external fixation in bicondylar tibial plateau fractures. The study included 13 patients (12 males, 1 female; mean age 27 years; range 18 to 37 years) who were treated with circular external fixation under arthroscopic control for bicondylar tibial plateau fractures. The causes of fractures were traffic accidents in nine cases, sport injuries in two cases, and fall from height in two cases. Eight patients had open fractures. The mean time from injury to presentation was two days. Soft tissue injuries were treated with curettage and excision. The fractures were classified according to the Schatzker's system. Functional results were assessed using the knee scoring system of Lysholm and Gillquist. The mean follow-up period was 35 months (range 16 to 38 months). There was no neurovascular pathology in any of the cases preoperatively and postoperatively. Lysholm and Gillquist knee scores were very good in two patients, good in six patients, moderate in four patients, and poor in one patient. The mean knee score was 82.46. The patient with the poor result had significant limitation in knee extension and flexion. Postoperative complications included superficial soft tissue infection in two patients and pin tract infection in six patients. Arthroscopically assisted circular external fixation of bicondylar tibial plateau fractures is efficient to obtain satisfactory functional results.

    ABSTRACT: Comminuted fractures of the patella are traditionally treated by internal fixation. The modified tension-band technique is widely accepted for internal fixation. The management of comminuted fractures often requires additional K-wire and/or circlage material and wide surgical exposure. Therefore, symptoms and complications related to the stainless steel wire are not uncommon in these cases. We present a new alternative treatment technique for comminuted patellar fractures. Five comminuted patellar fractures of four patients were treated by circular external fixator (CEF) under arthroscopic control. The mean patient age was 32.5 (range 24-41) years and mean follow-up was 22 (range 20-28) months. In four cases, union was completed by the sixth week; in the other case, union was completed by the eighth week. The frames were removed after union of the fracture was documented. When the CEF was removed, full knee range of motion was observed full in all patients, and the patients returned to their normal activities of living in a few days. The mean Lysholm score was 94 (range 85-100) after treatment. CEF application under arthroscopic control can help avoid some complications of the traditional treatment methods, particularly in comminuted fractures of the patella. The most important advantage of this technique is to allow active knee motion in the early postoperative period so patients can return to activity of daily living soon after the implant removal. In addition, arthroscopic examination of the knee joint provides an assessment of any other intra-articular lesions. This technique allows healing of the fracture with low morbidity.

    ABSTRACT: Developmental anomalies of the tendon of the long head of the biceps brachii are rare. The anatomic, embryologic, and anthropologic aspects of these variations have all been previously reported; however, some of their clinical examples have not yet been shown, such as the double structure of the long head of the biceps brachii. The purpose of this article is to describe a case of double structure of the LHB tendon in a patient with traumatic recurrent dislocation.

    ABSTRACT: Postoperative nausea and vomiting prolong the time spent in postanesthesia recovery units. In this study, we investigated the effect of neostigmine and atropine combination, used to avoid residual curarization, on nausea and vomiting. The study included 40 ASA I-II patients who were planned to have a short-term arthroscopic operation. The patients were administered a single dose of 0.4 mg/kg atracurium besylate for muscle relaxation, and then, were randomly divided into two groups. In group I, neuromuscular blockade was eliminated with 1.5 mg neostigmine and 0.5 mg atropine, whereas group II patients underwent spontaneous resolution. The patients were evaluated for nausea and vomiting and the need for antiemetic drugs in the recovery unit, patient room, and on the postoperative second day. There were no significant differences between the two groups with respect to hemodynamic parameters and peripheral oxygen saturation. The mean operation time did not differ significantly (p>0.05), but the mean extubation time was significantly shorter in group I (p<0.05). No significant differences were observed for the occurrence of nausea and vomiting and the need for antiemetic drugs in the recovery unit, patient room, and on the postoperative second day (p>0.05). In patients undergoing arthroscopic surgery, it is safe to use neostigmine and atropine combination before extubation to avoid residual neuromuscular blockade associated with the use of non-depolarizing myorelaxants.

    ABSTRACT: One of the most discussed subjects regarding anterior cruciate ligament (ACL) repair methods is femoral fixation. One of the materials often used for fixation in recent years is the EndoButton (Acufex Microsurgical, Mansfield, MA), which provides rapid and secure fixation. Although many reports about femoral fixation with EndoButton have been published, insufficient information is available on possible complications. We have used 240 EndoButtons in our clinic for ACL repairs since 1997. The goal of this study was to report a case of ACL repair with an EndoButton, in which we experienced a complication. In this case, the EndoButton dropped into the knee joint after 2 years.

    ABSTRACT: Lower extremity injuries secondary to close-range, low-velocity gunshot wounds are frequently seen in both civilian and military populations. A close-range, low-velocity injury produces high energy and often results in comminuted and complicated fractures with significant morbidity. In this study, four femoral, four tibial, and three combined tibia and fibular comminuted diaphyseal fractures secondary to close-range, low-velocity gunshot wounds in 11 military personnel were treated with debridement followed by compression-distraction lengthening using a circular external fixator frame. Fracture union was obtained in all without significant major complications. Fracture consolidation occurred at a mean of 3.5 months. At follow-up of 46.8 months, there were no delayed unions, nonunions, or malunions. Minor complications included four pin-tract infections and knee flexion limitation in two femur fractures. Osteomyelitis and deep soft tissue infection were not observed. This technique provided an alternative to casting, open reduction internal fixation, or intermedullary fixation with an acceptable complication rate.

    ABSTRACT: Dislocation that lasts longer than 3 weeks is called chronic or unreduced shoulder dislocation. Treatment alternatives can be closed reduction, open reduction, resection arthroplasty, prosthesis, arthrodesis, and no therapy. The English-language literature includes no evidence on arthroscopic reduction for the treatment of unreduced shoulder dislocation. The goal of our study was to present our technique and period results on the arthroscopic reduction we performed in 2 cases 4 and 5 weeks after anterior shoulder dislocation. Reduction could not be achieved by closed reduction under anesthesia. With arthroscopic visualization, adhesions within the joint were released with blunt dissection. Repeat reduction attempts were unsuccessful in these 2 cases. Labroligamentous lesions of the inferior glenohumeral ligament were repaired using 3 absorbable tacks. On the second day after the surgery, isometric exercises were started. The results were evaluated using a 100-unit test recommended by Rowe and Zarins (80 units in case 1; 85 units in case 2). Reduction of chronic unreduced shoulder dislocations using arthroscopy is an alternative technique for selected patients. It also allows repair and treatment of the intra-articular pathology in the joint and makes early postoperative rehabilitation possible.

    ABSTRACT: The aim of this study was to compare patients who had arthroscopic repair done following the first traumatic dislocation with patients who were treated conservatively, in terms of stability and function. Acute arthroscopic Bankart repair with absorbable tack was used in 30 shoulders after the first dislocation, while 32 patients who sustained traumatic anterior dislocation were treated conservatively at Gülhane Military Medical Academy, Department of Orthopaedics and Traumatology between March 1997 and April 2001. Preoperative and postoperative range of motion of the shoulder and Constant score of all patients were recorded. In the conservative group, the average pretreatment Constant score was 46.8 (range, 30 to 70) and the average post-treatment Constant score was 71.4 (range, 30 to 95). In the surgical group, the average preoperative Constant score in cases with Bankart lesion was 44.7 (range, 30 to 60) and the average postoperative Constant score was 92.3 (range, 65 to 100), (P = 0.0001). Our results support the use of acute arthroscopic repair of traumatic anterior shoulder dislocations with absorbable tacks. Arthroscopic repair is the treatment of choice in young and active patients who are having their first traumatic dislocation.

    ABSTRACT: In open, intra-articular distal humerus fracture caused by gunshot injury, full functional recovery is difficult to obtain. Three basic treatment methods are available: minimal internal fixation, open reduction-internal fixation, and external fixation. In Gülhane Military Medical Academy Department of Orthopedics and Traumatology, 19 of 20 cases of gunshot injuries were treated with circular external fixator between the January 1995 and December 2000. Nine (45%) cases were type III-A, eight (40%) were type III-B, and three (15%] were type III-C. Eight (40%) cases were brought to the hospital 6 to 8 hours after the injury and 12 (60%) were in late stage. An amputation was done in one case. Mean follow-up period was 34.3 (14-55) months. Union was achieved in all 19 of the cases, and circular external fixator was taken out in a mean period of 4.6 (3-7) months. In the early treatment group, three (42.9%) were good, three (42.9%) were moderate, and one (14.2%) was unsatisfactory. In the late treatment group, five (41.7%) were good, four (33.3) were moderate, and three (25%) were unsatisfactory. Circular external fixator can be preferred as a treatment alternative in selected cases of distal humerus intra-articular open communited fractures because it protects the soft tissue connections and blood circulation of bone fractured, permits early elbow movements, and allows the patient to return to daily life very early.

    ABSTRACT: We evaluated the results of non-cemented revision arthroplasty in patients who had undergone cemented total hip arthroplasty. Twenty patients (12 women, 8 men; mean age 72 years; range 61 to 84 years) underwent non-cemented revision arthroplasty after a mean of 9.4 years (range 3 to 16 years) following primary surgery. The mean follow-up period was 4.5 years (range 3 months to 6.3 years). During revision arthroplasty, femur fractures were observed in three patients (15%). Three patients (15%) had femoral cortex perforations. Trochanteric osteotomy was performed in five patients (25%). The mean Harris hip score after the operation was 76.7 (range 50 to 90). The results were excellent in three patients (15%), good in seven (35%), fair in seven (35%), and poor in three patients (15%). Despite a high intraoperative complication rate during non-cemented revision total hip arthroplasty, we believe that non-cemented revision should be the preferred method because of low infection and low aseptic loosening rates.

    ABSTRACT: The purpose of this prospective study was to assess changes in gait parameters after unilateral total hip arthroplasty and to correlate these objective changes with the results of subjective analyses. Thirty-eight patients (21 women, 17 men; mean age 61 years) with unilateral degenerative hip disease were evaluated in order to investigate preoperative and postoperative gait characteristics with the use of a gait evaluation mat (Gait Rite, USA). Each patient underwent at least two postoperative gait evaluations in the sixth and twelfth months, respectively. Gait evaluations were also made in a control group of 50 individuals without any neuromuscular and skeletal disease. Clinical evaluations were made using the Harris hip scoring system. All patients exhibited poor subjective evaluations preoperatively (Harris hip score <70). Compared to controls, patients had decreased step length and velocity, but increased stance, step, double support and swing times. Postoperatively, gait characteristics did not differ from those elicited prior to surgery in the first six months; however, patients attained near-normal velocity in the twelfth month. The recorded values for step length, step time, and double support time were similar to those of controls in both extremities. This study showed that total hip arthroplasty considerably improved the gait characteristics of patients with degenerative arthritis, and that this improvement could be measured and recorded quantitatively with the use of a walking band.

    ABSTRACT: Purpose: Most of ankle soft tissue injuries can be treated by conservative treatment. In this study, we evaluated our arthroscopic surgery applications in patients who do not respond to conservative treatment and still suffer from chronic pain, swelling, and limitation of movement ability. Patients and Methods: Between November 1991 and June 1998, we performed arthroscopic surgery in 22 ankles of 22 patients whose symptoms continued in spite of the conservative treatment applied. We used anterolateral and anteromedial portals as usual. Results: We observed chondral lesions in 16 cases with different grades and synovitis in 7 cases. Functional and subjective assessment were done according to criteria of Martin at al. Discussion: As a result of this study; we believe that arthroscopic surgery is useful both in diagnosis and treatment of cases whose symptoms continue although they receive conservative treatment. It helps the healing of synovitis and impingement due to that to a large extend and also symptomatic effect of joint lavage easifies the rehabilitation of the patients.
