Acute bilateral extensor pollicis longus tendon rupture following bilateral displaced distal radius fracture: A case report
No full textExtensor pollicis longus tendon ruptures are rarely reported after traumatic events, especially after distal radius fractures. Its classical presentation is a late-onset and unilateral rupture after a non-displaced distal radius fracture. In this case report, we present the treatment of a patient with acute bilateral extensor pollicis longus tendon ruptures after bilateral displaced distal radius fractures. The patient was treated with bilateral open reduction and volar plate fixation via a volar Henry approach for distal radius fractures and bilateral exten-sor indicis proprius tendon transfer for extensor pollicis longus tendon ruptures. We achieved satisfactory results, and no complications were reported with these treatment approaches. However, this case report demonstrates that extensor pollicis longus tendon rupture may occur at the time of fracture; thus, clinicians should be aware of this issue
Is the Acetabular Cup Orientation Different in Robot-Assisted and Conventional Total Hip Arthroplasty With Right-Handed Surgeons Using an Anterolateral Approach?
No full textIntroduction Total hip arthroplasty (THA) is one of the most successful orthopaedic procedures. Survival rates from 90% at 10 years to 93% at 20 years have been reported in different studies. Differences in implant and patient characteristics can undoubtedly explain some of this variability observed in prosthesis durability, but the effect of surgical technique and implant orientation cannot be ignored. Therefore, many intraoperative methods (anatomic landmarks, intraoperative x-ray, fluoroscopy, navigation, and robotic surgery) have been attempted to avoid acetabular component malpositioning. Although postoperative computed tomography (CT) is accepted as the gold standard for the measurement of acetabular anteversion, it remains controversial in respect of costs and radiation exposure. The aim of this study was to examine how acetabular component orientation was affected in robotic and conventional THA operations performed by two surgeons with right-hand dominance. Material and methods The study included 113 primary THA operations performed on 113 patients between 2017 and 2022 in two groups: (i) robotic THA (Mako, Stryker Corporation, Kalamazoo, Michigan, United States) (55 patients) and (ii) conventional THA (58 patients). The patients comprised 51 males and 62 females. THA was performed on 54 right-side hips and 59 left-side hips. The operations were performed by two orthopaedic surgeons, each with 20 years of arthroplasty experience, on all the patients in the lateral decubitus position with an anterolateral approach. In all the cases, the orientation of the acetabular component was 40° inclination and 20° anteversion. Difficult THA procedures (patients with developmental dysplasia of the hip (DDH), a history of hip surgery, revision THA, defect or deformity of the acetabulum, a history of scoliosis or lumbar posterior surgery, or those requiring proximal femoral osteotomy) were excluded from the study. Using the Liaw and Lewinnek methods, the acetabular component anteversion was measured on the radiographs taken in the optimal position postoperatively and the acetabular cup inclination angles were measured on the pelvis radiographs. The groups were compared using the Kolmogorov-Smirnov, Pearson Chi-square and Mann-Whitney U statistical tests. The limits were accepted as 40±5° for inclination and 20±5° for anteversion. Results No statistically significant difference was determined between the groups in respect of age, gender, or operated side. No statistically significant difference was determined between the optimal acetabular cup inclination angles of the robotic and conventional THA groups (p = 0.79). No statistically significant difference was determined between the optimal acetabular cup anteversion angles of the left and right conventional THA groups. Statistically significantly better results were determined in the robotic group in respect of acetabular cup anteversion (p<0,001). Conclusion The optimal orientation of the acetabular component is a key factor for successful THA. Otherwise, revision surgery is inevitable for reasons such as instability, impingement, or increased wear. The results of this study demonstrated that robotic surgery was superior to the conventional method in the placement of the acetabular component in the desired orientation
Does total knee arthroplasty affect overactive bladder symptoms in female patients?
No full textIntroduction and hypothesis In the current study we hypothesized that total knee arthroplasty might improve the overactive bladder symptoms by providing pain relief and improving physical function. Methods One hundred patients who underwent total knee arthroplasty were preoperatively evaluated for overactive bladder and 47 patients that met inclusion criteria were included in this study. All the patients included in the study were assessed both preoperatively and at the 3rd month postoperatively using the Overactive Bladder-Validated 8 (OAB-V8) questionnaire for overactive bladder symptoms, the Oxford Knee Score (OKS) for pain and physical function, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) for physical activity. Results The mean age of the patients was 65.4 +/- 7 (56-83) years. The OAB-V8, OKS and IPAQ-SF scores significantly improved at the 3rd month postoperatively compared with the initial assessment. All the OAB-V8 domains, namely, frequency, urgency, nocturia, and urgency urinary incontinence, significantly improved following total knee arthroplasty. Conclusions Our results showed that following total knee arthroplasty, overactive bladder questionnaire scores significantly improved at the 3rd month postoperatively
Cervical and thoracic/lumbar motion and muscle strength in surgically treated adolescent idiopathic scoliosis patients
No full textAbstract: BACKGROUND: To date, only one study assessed the spinal mobility and muscle strength of patients who were treated either with fusion or brace treatment. OBJECTIVE: The aim of this retrospective study was to evaluate the range of motion (ROM) and strength of the cervical and thoracic/lumbar spine in patients who underwent spinal fusion for the treatment of adolescent idiopathic scoliosis (AIS) in comparison to healthy individuals. METHODS: Patients (n= 28) who were treated surgically for AIS were included in the study. An age and gender matched control group (n= 22) was included that consisted of healthy individuals. DAVID® Lumbar/Thoracic Extension, Lumbar/Thoracic Rotation, and Cervical Extension/Lateral Flexion devices were used to measure cervical and lumbar/thoracic ROM as well as muscle strength. RESULTS: Significant differences were observed between groups in all ROM measurements except thoracic/lumbar sagittal flexion ROM measurement (p= 0.198). There were significant differences between groups in terms of muscle strength, except thoracic lumbar left rotation strength (p= 0.081). CONCLUSIONS: The findings of the current study demonstrated that cervical and thoracic/lumbar range of motion, as well as muscle strength, were significantly decreased in surgically treated adolescent idiopathic scoliosis patients compared to healthy counterparts. However, trunk (thoracic/lumbar) flexion range of motion and trunk left rotation muscle strength were not significantly different
Volumetric Analysis of Subacromial Space After Superior Capsular Reconstruction for Irreparable Rotator Cuff Tears
No full textPurposeSubacromial volume measurement on magnetic resonance images is relatively new. It has been shown that decreased subacromial volume increases after surgical repair of full-thickness rotator cuff tears. There is no study examining subacromial volume changes after superior capsular reconstruction (SCR). The purpose of this study was to compare subacromial volume changes on magnetic resonance images (MRI) after superior capsular reconstruction performed for primary irreparable rotator cuff tears.MethodsPatients who underwent an SCR procedure between 2017 and 2019 with a minimum 2-year postoperative follow-up were included in this retrospective study. Subacromial volume was measured on MRI using software. The preoperative and postoperative acromiohumeral distance, Constant Scores, graft thickness, and Hamada grades of the patients were evaluated.ResultsA total of 18 patients with a mean age of 59.7 years (range: 49-74 years) underwent an SCR for massive irreparable cuff tear. The mean preoperative subacromial volume was 3.54 +/- 0.39 cm(3) (range 2.88-4.36 cm(3)), which increased to 4.46 +/- 0.39 cm(3) (range 3.75-5.32 cm(3)) postoperatively (p = < 0.001). The increase in subacromial volume and acromiohumeral distance did not correlate with Constant scores and graft thickness. We observed a significantly higher subacromial volume increase among Hamada grade 1 patients, compared to those with Hamada grade 2 (p = 0.011).ConclusionsWe observed that subacromial volume significantly increased after superior capsular reconstruction. However, the increase in subacromial volume did not correlate with clinical scores, acromiohumeral distance changes, or graft thickness

Turan and Ramsey numbers in linear triple systems II
No full textIn this paper we continue our studies of Turan and Ramsey numbers in linear triple systems, defined as 3-uniform hypergraphs in which any two triples intersect in at most one vertex. In [7] the two main problems left open were the Turan number of the wicket and the Ramsey property of the sail. In this paper we present some progress towards both of these problems.(c) 2022 The Author(s). Published by Elsevier B.V.

Altay Türklerinin Geleneksel Aile Yapısı
No full textFamily institution is the oldest building stone of human history. Despite the changes in the social and human values of the family structure, their basic characteristics are the same. The establishment of the family, the healthy continuation of the establishment, the peace, peace, love and respect concepts of the institution are changing from people to people. Altai family structure has very rich resources in this respect. The forms of marriage that constitute the structure of the family institution should be investigated in terms of marriage age, stages of marriage, family institution, concept of child in family, continuity of family establishment, social, cultural and religious aspects. Altays value is the most important feature of Turkish peoples, which is interesting. It is the living of the beliefs of Christian, Buddha and Shamanism in the same soil. Naturally, these beliefs were also influential on the Altay family structure. I would like to emphasize the traditional family structure of the Altay people, especially the traditions and customs within the family in the family
Arterial stiffness measured via carotid femoral pulse wave velocity is associated with disease severity in COPD
No full textOzkaya, Sevket/0000-0002-8697-4919; Durakoglugil, Emre/0000-0001-5268-4262; KAYHAN, SERVET/0000-0003-4226-2781; Erdogan, Turan/0000-0003-2986-5457BACKGROUND: Patients with COPD face an increased risk of cardiovascular disease and increased cardiac mortality. Carotid femoral pulse wave velocity (cf-PWV) is a validated measure of arterial stiffness, a well recognized predictor of adverse cardiovascular outcomes, and offers higher predictive value than classical cardiovascular risk factors. We investigated the association between COPD and arterial stiffness using cf-PWV as a noninvasive technique. METHODS: This clinical study was prospective, observational, and cross-sectional. Sixty-two subjects with stable COPD and 22 healthy controls underwent physical examination, chest x-rays, pulmonary function tests, arterial blood gas analysis, and 6-min walk test, and cf-PWV was measured via a validated tonometry system. RESULTS: the COPD subjects had greater arterial stiffness than the control subjects, and that difference was associated with lower FEV1, P-aO2, and oxygen saturation during the 6-min walk test. We observed higher cf-PWV in the COPD subjects with severe COPD than in the subjects with mild to moderate COPD. Only FEV1 was an independent predictor of cf-PWV. CONCLUSIONS: Our results suggest that arterial stiffness is increased in subjects with more severe and advanced COPD than in those with mild to moderate COPD. Air flow limitation and hypoxemia may induce increased arterial stiffness in COPD patients
