No full textThe minimally invasive osteosynthesis technique has gained attention in fracture treatment in recent years. The aim of this study was to evaluate the effects of the minimally invasive plate osteosynthesis (MIPO) technique, on clinical and radiological outcomes in the surgical treatment of AO-OTA Type B (wedge) clavicular midshaft fractures. This prospective study included twenty-three patients who were diagnosed with acute clavicular midshaft fracture where surgical intervention was indicatedand MIPO was performed between February 2014 and April 2016.Exclusion criteria were patients with non-displaced fractures, pathological fractures, open fractures, cases where theindex trauma was three weeks ago, or those with concomitant neurovascular injuries.The patients comprised of 16 males and 7 females with a mean age of 36.5 years (range, 18-65 years).The mean time from trauma to surgery was 6.1 days (range, 3-12 days).The mean follow-up period was 15.3 months (range: 12-18 months). The mean duration of surgery was 65.5 mins (range: 50-80 mins). Anatomic reduction was obtained in 11 (47%) patients, of whom 7 were Type B1, 4 were Type B2, and 1 was Type B3. The mean time to union was found to be 15.9 weeks (range: 10-24 weeks). After union was confirmed, the mean Constant Murley score was 83 (range: 68-92) and the mean UCLA score was 29.95 (range: 23-34). The mean proportional length difference in the clavicle was 0.32% (range:-0.55 to +1.63).There was no statistically significant difference for the Constant Murley score and UCLA score between patients with anatomic reduction achieved and not achieved (p=0.36, p=0.43 respectively). Osteosynthesis with a minimally invasive percutaneously applied plate (MIPO) could be a successful therapeutic option for the management of acute, displaced AO OTA Type B clavicular midshaft fractures.

Biomechanical comparison of rotator cuff repair techniques in osteoporotic conditions: testing a novel technique
No full textObjective: This study aimed to compare the biomechanical characteristics of conventional transosseous equivalent (TOE) techniques
with those of the novel free independent double-row medial fixation method, using rigid polyurethane (PU) foam blocks to simulate
osteoporotic humerus bone.
Methods: In this biomechanical study, 4 groups were tested using rigid PU foam blocks with osteoporotic properties and bovine infraspinatus tendons to simulate the rotator cu!. Groups 1 and 2 employed conventional TOE techniques: medial row knotted repair and knotless repair, respectively. Groups 3 and 4 utilized the “free independent double-row medial fixation method,” di!ering in the order of suture tying. Several biomechanical characteristic and pressure parameters were measured.
Results: Groups 3 (0.16 ± 0.04 MPa) and 4 (0.17 ± 0.05 MPa) achieved significantly higher initial contact pressure compared to standard TOE techniques (P=.039). While contact area (Group 3: 102.4 ± 55.0 mm", Group 4: 110.4 ± 37.2 mm") and ultimate failure force (Group 3: 212.0 ± 26.5 N, Group 4: 214.7 ± 30.2 N) were relatively higher, the di!erences were not statistically significant (P=.135 and P=.3, respectively). The overall failure types included medial anchor pullout (40%) and suture/tendon stripping (32.5%), with no significant di!erences among groups (P=.260).
Conclusion: With superior contact pressure and comparable ultimate failure and contact area measurements, the novel independent double-row medial fixation technique may be a viable alternative to conventional TOE techniques for enhancing medial row stability in osteoporotic conditions.

Feasibility of diagnosing osteoporosis using routine computed tomography scans for hip fractures: Correlation with histopathological diagnosis of head and neck regions
No full textObjective: The aim of this study was to demonstrate the feasibility of diagnosing osteoporosis through routine computed tomography (CT) by assessing the association between the histopathological assessment of femoral head specimens extracted from patients who underwent surgery for intertrochanteric fractures and the Hounsfield unit (HU) measurements derived from preoperative CT scans.
Methods: Forty-eight patients who presented to our clinic between November 2019 and May 2020 with hip fractures and underwent partial prosthesis fixation were included in this retrospective study. Hounsfield unit measurements were performed on the head and neck regions using dual-energy x-ray absorptiometry (DEXA) and CT scans, respectively. The trabecular ratio per unit area was calculated using the Nikon Imaging Software (NIS-Elements ) program in the pathology laboratory from digitally captured images of the removed head and neck specimens.
Results: The mean HU receiver operating characteristic analysis had a sensitivity of 77% and a specificity of 87%, with a cutoff value of 77.68. There was a moderate correlation between the mean trabecular density and the mean HU of the femoral head (P=0.013, r=0.340). Additionally, there was a significant correlation between the mean HU and the T-score of the head, although this correlation was not found with the maximum–minimum HU. Although there was a significant correlation between trabecular density and mean HU, the correlation coefficient indicated a moderate relationship. This relationship was also observed between the inferior sections of the head and the trabecular density and HU (P=.018). However, no significant correlation was found between the T-score and the trabecular structure of the head (P=.977).
Conclusion: The results of the present study suggest that conventional CT has the potential to serve as a diagnostic tool for osteoporosis and may offer a more precise and accurate method for evaluating the success of intraosseous implants when compared to T-scores without the need for additional tests or procedures.

Echocardiographic findings in newborns of gestational diabetic mothers and its relationship with somatomedin-C
No full textBackground: Diabetes is an important disease that affects fetal development during pregnancy and causes metabolic disorders in newborns. Changes in serum glucose, ketone bodies, and somatomedin-C inhibitors in the diabetic pregnancies are responsible for the development of metabolic syndromes. The frequency of maternal hyperglycemia has reduced with careful monitoring during pregnancy of diabetic mothers. Nevertheless, morbidity in offspring of mothers with gestational diabetes mellitus (GDM) continues to be significant. We aimed to investigate the cardiac function of infants of mothers with GDM by echocardiographic (ECHO) Doppler and tissue Doppler methods and to evaluate their demographic features, somatomedin-C level and the relations them with each other
Idiopathic talipes equinovarus with preaxial polydactyly of the foot: a case report
No full textThe aim of this study is to report an unusual combination of congenital idiopathic talipes equinovarus with preaxial polydactyly of the foot. A newborn infant was brought to the polyclinic at the age of 1 week. In the right foot, preaxial polydactyly was seen in addition to the club foot deformity. The preaxial polydactyly of the patient was surgically excised. The sutures were then removed and a series of plaster casts were applied according to the Ponseti method Then a Dennis-Brown brace was applied with both feet. This case shows that combination of congenital idiopathic talipes equinovarus with preaxial polydactyly of the foot can be treated succesfully by apply the standard Ponseti method after the surgical excision of the polydactyly.

No full textBackground: Myocardial iron overload is the most common cause of mortality in patients with thalassemia major (TM), also known as beta-thalassemia. T2* cardiovascular magnetic resonance imaging (MRI) is the best way of monitoring cardiac iron, and new echocardiographic techniques can be used to assess cardiac function
Regression of Cardiac Rhabdomyomas in a Neonate after Everolimus Treatment
No full textCardiac rhabdomyoma often shows spontaneous regression and usually requires only close follow-up. However, patients with symptomatic inoperable rhabdomyomas may be candidates for everolimus treatment. Our patient had multiple inoperable cardiac rhabdomyomas causing serious left ventricle outflow-tract obstruction that showed a dramatic reduction in the size after everolimus therapy, a mammalian target of rapamycin (mTOR) inhibitor. After discontinuation of therapy, an increase in the diameter of masses occurred and everolimus was restarted. After 6 months of treatment, rhabdomyomas decreased in size and therapy was stopped. In conclusion, everolimus could be a possible novel therapy for neonates with clinically significant rhabdomyomas

No full textRight atrial appendage aneurysm is a very rare condition which can be asymptomatic or can cause arrhythmia or life-threatening thromboembolism. We report a case of newborn with right atrial appendage aneurysm who was diagnosed with fetal echocardiography. Anticoagulant therapy was applied to prevent thromboembolism and he is still going on follow-up without any complaint
Clinical and radiological results of radial shortening osteotomy, and proximal row carpectomy in Kienbocks Disease
No full textIn this prospective study, we aimed to evaluate the clinical and radiological results of our patients treated with radial shortening osteotomy (RSO) and proximal row carpectomy (PRC) together with a short review of the literature. The study included 35 patients with the diagnosis of Kienbock disease RSO was performed for 17 patients and 18 patients underwent PRC. 15 of the patients had Lichtman Stage 2, 14 patients had Stage 3A and 6 patients had Stage 3B disease. Q-DASH Score, Preoperative and postoperative carpal height ratio (CHR), revised CHR, stahl index, radial inclination values were noted. Preoperative and postoperative flexion-extension range of Motion (ROM) and ulnar deviation angles were also obtained. Nakamuras clinical evaluation system was performed to each patient. Results of clinical evaluation revealed significant progression at postoperative sixth month follow-up. Our results showed clinical improvement following surgeries of both RSO and PRC for Lichtman Stage 2, 3a and 3b disease. We consider that experience and technical familiarity of the surgeon is key factor to decide the type of the procedure to be performed. [Med-Science 2017; 6(3.000): 526-30
