Unstable trochanteric femur fractures in elderly patients with osteoporosis are still challenging. Gamma3 nail with the U-blade lag screw (U-blade gamma nail) has been developed to improve mechanical stability of proximal femoral fragment. This study aimed to compare the clinical and radiologic outcomes of U-blade gamma nail to proximal femoral nail antirotation (PFNA), and standard Gamma3 nail (gamma nail) for unstable trochanteric femur fractures. A retrospective matched-pair case study was performed with U-blade gamma nail, PFNA, and gamma nail. During 2012-2018, 970 patients with unstable trochanteric femur fractures were reviewed. Matching criteria were set as follows 1) sex; 2) age (± 3 years); 3) body mass index (± 2 kg/m ); 4) bone mineral density (± 1 T-score in femur neck). Finally, a total of 159 patients were enrolled. We assessed the tip-apex distance (TAD), neck shaft angle, and hip screw sliding distance using plain radiographs. Also, we evaluated the clinical outcomes with Koval's grade and fixation failure during 2 years. The mean postoperative TAD was not significantly different among the 3 groups (p = 0.519). However, the change in the TAD at 1 year (p = 0.027) and 2 years (p = 0.008) after surgery was significantly smaller in U-blade gamma nail group compared with PFNA and gamma nail group. The hip screw sliding distance at 1 year (p = 0.004) and 2 years (p = 0.001) after surgery was significantly smaller in U-blade gamma nail group compared with PFNA and gamma nail group. However, there was no significant difference of Koval's grade and fixation failure among the 3 groups (p = 0.535). U-blade gamma nail showed favorable radiologic results in terms of the change in the hip screw position. However, U-blade gamma nail was not superior to PFNA and gamma nail in clinical outcomes.U-blade gamma nail showed favorable radiologic results in terms of the change in the hip screw position.

In parallel with technological developments, surgical experience has increased and several cardiac operations are able to be performed using different mini-incisions. In this review, we discuss approaches to minimally invasive cardiac surgery, incisions, technical details, and suggestions.Cannulation of the shorter limb of an abdominal aortic endograft can be demanding. Confirmation of the accurate cannulation is equally challenging. Interventional cardiologists and cardiovascular surgeons may encounter certain difficulties during this procedure. In particular, cardiologists have a wide variety of experience in interventions from coronary practice. This novel method we describe herein consists of peripheral balloon usage in wiring the short limb of an aortic stent graft. In this method, an over-the-wire peripheral balloon is employed to centralize the wire at the gate of the short limb. The centralized wire in three-dimensional arterial lumen can cross the short limb of the graft easily.The subxiphoid incision has been widely used in videothoracoscopic surgery in recent years. This minimally invasive technique allows to reach both lungs from a single port. With the future development of the surgical instruments required for the technique, it is expected to become more commonly used. Herein, we report the first case of bilateral pulmonary metastasectomy performed with a subxiphoid single incision in Turkey.Primary pulmonary meningiomas are rare and mostly benign tumors. They usually appear as a solid peripheral pulmonary nodule on chest radiography and computed tomography and are frequently diagnosed incidentally. Herein, we report a 55-year-old female case of primary pulmonary meningioma mimicking pulmonary metastasis.A 51-year-old female patient was admitted to our clinic with numbness and anesthesia in the left upper extremity. find more There was widespread peripheral edema above and below the left elbow. Symptoms of the patient were associated with axillary lymphatic nodular dissection during previous the mastectomy operation. The patient was successfully treated using the supermicrosurgery technique via lymphaticovenular anastomosis.Left subclavian artery originating from the left pulmonary artery is a rare aortic arch anomaly. Herein, we, for the first time in Turkey, present a case of left subclavian artery originating from the left pulmonary artery via ductus arteriosus in DiGeorge syndrome and causing subclavian steal syndrome.Left ventricular assist device outflow graft stenosis is a rare, but a lethal complication. Device replacement or thrombolytic treatments are associated with serious mortality and morbidity. Implantation of covered stents is a less invasive option. Herein, we represent a successful stent placement of two cases with outflow graft stenosis, which we performed by leaving the stents on the aortic side of the anastomosis line 5 to 10 mm. This treatment option can be used reliably in cases of stenosis of the outflow graft with part of the stent leaving the aorta.A complete sternal cleft is a very rare congenital anomaly causing severe respiratory compromise. Surgical reconstruction options are limited, particularly in low birth weight newborns. Herein, we report a case of low birth weight premature newborn with a complete sternal cleft and its surgical treatment.An inferior mesenteric artery aneurysm is considered one of the visceral artery aneurysms, which is extremely rare, although its incidence of detection has been increasing in recent years. A 59-year-old male patient with a renal cell carcinoma in the left kidney was diagnosed with an inferior mesenteric artery aneurysm and treated surgically. Computed tomography revealed atrophy of the right kidney and occlusion of the celiac trunk, superior mesenteric artery, and left renal artery. There were no complications during the hospital stay and no mortality or morbidity was observed at three months of follow-up. In conclusion, the treatment of inferior mesenteric artery aneurysms is usually recommended, due to possible complications such as rupture and thromboembolism with high mortality and morbidity rates.
