This condition can be congenital or acquired, often remains asymptomatic, and is only discovered incidentally during radiological imaging. This study aims to present a comprehensive retrospective analysis of bipartitism in tarsal bones, assessing its prevalence, type of articulation, and associated clinical features in a cohort of patients. Materials and Methods: A total of 4,645 patients were retrospectively evaluated from 6,145-foot images consisting of 4,975 computed tomography (CT) and 1,170 magnetic resonance imaging (MRI) scans obtained between 2015 and 2023. 15 patients with tarsal bipartitism were identified and contacted through the hospital system for in-person medical history and examination. Radiological exams assessed partial and complete bipartition, diastasis, and exostosis in the tarsal bones. Age, sex, side, trauma history, pain, foot deformity, gait disturbance, and other clinical findings were also recorded. Results: Bipartitism was detected in 15 patients (0.32%), predominantly affecting males (87%). The most common variant was medial cuneiform bipartitism, observed in 13 patients (0.28%). Talus and calcaneus bipartitism were each observed in one patient (0.02%). Bilateral involvement was present in 67% of the cases, with 60% of patients reporting chronic pain. Complete dissociation of bipartite bones was noted in 80% of cases. Accompanying bipartitism, two patients had pes planovalgus, and one had hallux varus deformity. Conclusion: Although bipartitism of the tarsal bones is rare, it remains a diagnostic challenge due to variability in clinical presentation and possible association with other foot deformities. Accurate diagnosis through advanced imaging techniques is essential to differentiate these variants from fractures and guide appropriate treatment. This study contributes valuable insights into the prevalence and clinical impact of bipartitism in the tarsal bones, emphasizing the importance of early diagnosis and individualized treatment strategies.Öğe Cardiac Findings on Non-Contrast Thoracic Tomography in Patients with Acromegaly(2022) Keskin, Lezan; Ilgar, Mehtap; Yaprak, Bülent; Akçiçek, Mehmet; Aslantürk, OkanAim: Acromegaly occurs as a result of excessive and permanent secretion of growth hormone from the pituitary. Mortality is mostly related to cardiovascular system involvement. In our study, we aimed to evaluate the correlation between epicardial fat volume (EFV) and growth hormone level in thorax computed tomography in patients with acromegaly and coronary artery calcification, pulmonary artery diameter, ascending aorta diameter, cardiothoracic ratio (CTO) measurements with the control group patients. Method: Our study was retrospective and included 16 patients with acromegaly who were previously diagnosed and treated by the endocrinology clinic and a control group consisting of 32 patients matched for gender and age.In thorax CT, EFV measurement of the patients was performed and main pulmonary artery diameters, ascending aorta diameters, cardio thoracic ratios, presence of coronary artery calcification were evaluated. Results: The number of patients with large ascending aorta was higher in patients with acromegaly and it was statistically significant (p=0.041). Although the rate of patients with large main pulmonary artery diameter was higher in patients with acromegaly, no significant difference was found between the groups (p=0.355). There was no significant difference between the groups in terms of increased CTO (p=0.818) and coronary artery calcification (p=0.157). Conclusion: In our study, a difference was found between the acromegaly and control group patients only in terms of ascending aorta diameters, but no significant difference was found in terms of other parameters. We think that regular follow-up and treatment of patients is effective in this result. Cardiovascular risks can be reduced in patients with acromegaly with early diagnosis, regular follow- up and treatment.Öğe Clinical results of anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft: A prospective study(2018) Görmeli, Gökay; Görmeli, Ayşe Cemile; Yılmaz, Özgür; Ergen, Emre; Aslantürk, OkanAbstract: Aim: Anterior cruciate ligament(ACL) injury is the most common ligament injury of knee. Gold standard treatment of ACL rupture is reconstruction of ligament with autograft or allograft. There is still controversy in graft choice in literature. In this study, we aimed to present prospective follow-up results of patients who were reconstructed with bone-patellar tendon-bone autograft for ACL rupture. Material and Methods: Twenty-seven patients were operated for ACL rupture with bone-patellar tendon-bone(B-PT-B) autograft ACL reconstruction. Patients were followed for at least 2 years. Patients were evaluated preoperatively and postoperatively with Lysholm knee function score, IKDC objective score and Tegner activity level scale. Development of arthritis were evaluated radiologically. Results: All of operated patients were male. The mean age of the patients was 25.4 (range 19-35 years). The mean follow-up time was 27.9 (range 24-30 months). There was a statistically significant increase in all postoperative knee scores. Hematoma, requiring surgical drainage, developed in two patients. Six patients had anterior knee pain while kneeling at final follow up. Conclusion: ACL rupture causes knee instability that can lead early knee arthritis and meniscal injuries. Patients with ACL rupture showed increased knee stability and functional scores after reconstruction. Anterior cruciate ligament reconstruction with B-PT-B autograft incorporates and heals faster with low rerupture and complication rate.Öğe A Clue Finding for to Detect the Localization of Pellet in Elbow Arthroscopy(2015) Ertem, Kadir; Görmeli, Gökay; Karakaplan, Mustafa; Aslantürk, Okan; Yılmaz, Özgür; Karakoç, YunusAbstract: In this case report, we aimed to share our experience of arthroscopic finding of chondral lesion can be helpful to detect the location of pellet that between brachial muscle and capsule in a 15 years male subject with left elbow gunshot injuryÖğe Corticosteroid-induced avascular necrosis of the femoral head is increased in the treatment of COVID-19 pandemic(2023) Oklu, Yunus; Ertem, Kadir; Aslantürk, OkanIschemia of an appendage caused by dressing, tourniquet or hair is a rare, but devastating clinical entity. A six-year-old girl presented to the emergency department with necrosis of her right thumb caused by compressive dressing for four days. The patient was treated with an immediate surgical decompression and the thumb was saved. The patient had a full range of the thumb at 10 months of follow-up. In conclusion, instead of waiting for full demarcation, timely surgical interventions may protect the fingers from being amputated.Öğe Flexor Digitorum Profundus Injury in a Newborn: A Case Report(2015) Köroğlu, Mehmet; Ertem, Kadir; Ergen, Emre; Aslantürk, Okan; Braam, De LepeleereAbstract: Injuries of flexor digitorum profundus tendons in children are rare, certainly in newborns. In this case report, we discuss the presentation, treatment and outcome of a profundus tendon injury of the fifth finger of a ten days old baby. The tendon injury in this case was caused by a knife cut, unrelated to cesarean sectio. To our knowledge, this is the first report about a flexor digitorum profundus injury and repair in a newborn of this ageÖğe Functional outcomes of titanium elastic nail procedure after femoral shaft fracture in pediatric patients(2023) Karakaplan, Mustafa; Ergen, Emre; Köroğlu, Muhammed; Aslantürk, Okan; Özdeş, Hüseyin Utku; Gündüz, EnesPediatric femur diaphyseal fractures are seen after serious traumas such as traffic accidents and fall from height. Although treatment algorithms are made according to age groups, treatment planning is individualized according to the patient and the degree of injury. In our study, we evaluated functional outcomes of pediatric femur fractures treated with titanium elastic nail (TEN). This is a retrospective study including pediatric femoral diaphyseal fractures treated with TEN between 2012 and 2021. Open fractures, pathological fractures, distal fractures involving the femoral condyles, and proximal fractures involving the trochanteric region were not included in our study. Thirty-three femoral diaphyseal fractures with complete data were identified as stable and unstable in length, and functional results and post-treatment complications were recorded by performing TEN in fracture fixation. Clinical functional results were analyzed with Flynn criteria. Thirty-three femoral fractures of 29 patients were included. Eighteen (62.1%) of our patients were boys and 11 (37.9%) were girls. The mean age was 6.51 years (4-13 years). The most common injury mechanism was traffic accidents seen in 19 patients (24.51%). The mean follow-up period after surgery was 26.6 (6-90 months) months. Stable fractures (transverse and short oblique) were found in 26 cases (78.7%) and unstable fractures (spiral/long oblique and comminuted) in 7 cases (21.7%). According to Flynn criteria, excellent results were found in 20 fractures (60.6%) and satisfactory results in 10 fractures (30.3%) and 3 poor (9.09%). There was no significant difference between stable and unstable fractures in terms of functional outcome (p=0.12). Femoral diaphyseal fractures are serious injuries that require surgery. Regardless of the type of fracture, stable or unstable in length, the results of treatment with TEN are very successful. Major complications such as nonunion and re-fracture are rarely seen with this treatment.Öğe Functional results after surgical treatment of pediatric femoral neck fractures(2023) Köroğlu, Muhammed; Aslantürk, Okan; Özdeş, Hüseyin Utku; Çoban, İdrisThis study aims to present the functional outcomes of patients who were treated surgically for childhood femoral neck fractures. In addition, to obtain information about the complications seen after these fractures, especially avascular necrosis of the femoral head (AVN), and to investigate the relationship with the treatment process. Our study is a retrospective study including 22 fractures of 22 patients operated for femoral neck fractures between 2012 and 2021. Thirteen of the patients were boys and 9 were girls The mean age at the time of trauma was 12.6 years (5-17 years). The fractures were classified based on the Delbet/Colonna classification. Fracture type and its effect on functional outcomes and the effect of fracture type on complications were investigated. The relationship between the time and type of treatment and AVN was evaluated. The mean follow-up period of the patients included in the study was 36.9 (12-132 months) months. Orthopedic injury in combination with femoral neck fracture was seen in 4 patients. Femoral neck fractures were classified as type 1 in 1 patient, type 2 in 15 patients, type 3 in 4 patients, and type 4 in 2 patients. In our study, 5 of 8 complications were AVN. The clinical results of the patients were classified with Ratliff score and 14 patients had good, 3 patients had fair and 5 patients had poor results. According to this classification system, 5 patients who developed AVN had a poor outcome, but no significant correlation was found between AVN and the timing of surgery and treatment method. All of the cases with AVN were Type 1 and Type 2 fractures. Pediatric femoral neck fractures are inherently difficult fractures for orthopedists who need long-term follow-up. Although the appropriate time, methods, and materials for surgical management are frequently discussed, the severity of the injury and the anatomical location of the fracture is most important in the development of AVN.Öğe An investigation of infection rate and seasonal effect level in total joint replacement cases(2018) Arslan, Aydın; Görmeli, Gökay; Harma, Ahmet; Ertem, Kadir; Aslantürk, Okan; Sevimli, ReşitAbstract: This study aims at evaluating gender, age range and seasonal differences in patients who developed articular infection after undergoing joint prosthesis in our clinic. This study is a retrospective screening of advanced articular arthrosis patients who had undergone total joint arthroplasty of the upper and lower extremities between 2009 and 2016. Of 504 patients who had been treated with total joint replacement, our study includes 468 patients we could follow up or contact by phone and who had been applied 559 primary or revision total knee arthroplasty. The mean age of these patients was 58.9 (ranging from 41 to 74). We detected infection in 22 (3.9%) total joint arthroplasty patients. Of these 14 (63.63%) were females and 8 (36.36) were males. There was no statistically significant difference between infection rates in terms of seasonal distribution nor gender or age range. In the light of our findings, we concluded that gender, age range and seasonal differences have no effect on infection rates in total joint replacement cases.Öğe Metacarpal osteomyelitis secondary to human bite: a case report(Turgut Özal Tıp Merkezi Dergisi, 2017) Sevimli, Reşit; Salih, Arsan Hussien; Aslantürk, Okan; Canbay, AliAbstract The injuries resulting from Human bite are rarely seen in the clinical practice. It accounts for approximately 0.1% of injuries presenting to emergency service (1), and for about 2% of all bite wounds (2). Human bite injuries happens usually during fights and rarely occurs accidentally during sports activityes. If neglected, human bites can cause serious infective complications due to the high concentration of microorganisms in the oral cavity. Wound dressing and oral antibiotics for the treatment of human bite is not an adequate method of treatment; Wound exploration, extensive debridement and adequate wash should be considered under operative condition followed by broad-spectrum intravenous antibiotics therapy. In this presentation we aimed to present a case of phalanx fracture after a human bite who received treatment for acute osteomyelitis.

Methods A total of 162 patients with different stages of knee OA were randomly divided into four groups receiving 3 IA doses of PRP, one dose of PRP, one dose of HA or a saline injection (control). Then, each group was subdivided into two groups: early OA (Kellgren–Lawrence grade 0 with cartilage degeneration or grade I–III) and advanced OA (Kellgren–Lawrence grade IV). The patients were evaluated before the injection and at the 6-month followups using the EuroQol visual analogue scale (EQ-VAS) and International Knee Documentation Committee (IKDC) subjective scores. Adverse events and patient satisfaction were recorded. Results There was a statistically significant improvement in the IKDC and EQ-VAS scores in all the treatment groups compared with the control group. The knee scores of patients treated with three PRP injections were significantly better than those patients of the other groups. There was no significant difference in the scores of patients injected with one dose of PRP or HA. In the early OA subgroups, significantly better clinical results were achieved in the patients treated with three PRP injections, but there was no significant difference in the clinical results of patients with advanced OA among the treatment groups. Conclusion The clinical results of this study suggest IA PRP and HA treatment for all stages of knee OA. For patients with early OA, multiple (3) PRP injections are useful in achieving better clinical results. For patients with advanced OA, multiple injections do not significantly improve the results of patients in any group.Öğe Multiple PRP injections are more effective than single injections and hyaluronic acid in knees with early osteoarthritis a randomized double blind placebo controlled trial(Knee Surgery, Sports Traumatology, Arthroscopy, 2015) Görmeli, Gökay; Görmeli, Cemile Ayşe; Ataoğlu, Baybars; Çolak, Cemil; Aslantürk, Okan; Ertem, KadirPurpose To compare the effectiveness of intraarticular (IA) multiple and single platelet-rich plasma (PRP) injections as well as hyaluronic acid (HA) injections in different stages of osteoarthritis (OA) of the knee.

Çocuk ekstansiyon ve pronasyondaki kolu üzerine düşerken vücut ağırlığı dirsek ekleminde torsiyonel bir güç uygulayarak humerus ve ulnayı dış rotasyona zorlar. Ulna deforme olduğunda radius başının hiperpronasyona zorlanması devam eder. Eğer torsiyonel kuvvet yeterince büyükse radius başı çıkacak ayrıca ulna plastik deformasyonu da aşılırsa ulna kırılacaktır. Bu kırığın komplikasyonları kaynamama, radiohumeral ankiloz, radioulnar sinostoz, tekrarlayan radius başı çıkığı ve posterior interosseoz ya da radial sinir felcidir. Sinir felci genellikle kendiliğinden iyileşir ve nadiren eksplorasyon gerekir. Bu makalede, 7 yaşındaki kız hastada Monteggia kırıklı çıkığı sonrası radius başı basısına bağlı gelişen ve cerrahi olarak tedavi edilen radial sinir felci olgusu sunulmaktadır.Öğe Pediatrik hastada monteggia kırığının nadir bir komplikasyonu radial sinir tuzaklanması: olgu sunumu(İnönü Üniversitesi Tıp Fakültesi Dergisi, 2013) Ergen, Emre; Korkmaz, Mehmet Fatih; Aslantürk, Okan; Özen, Metehan; Ertem, KadirMonteggia fracture-dislocation is combination of proximal ulna fracture with radial head dislocation. When a child is falling on his/her arm in an extension and pronation position, body weight forces the elbow joint to external rotation by applying torsional strength to humerus and ulna. In this situation, deformed ulna will continue to force the radial head to hiperpronation. If the torsional force is large enough radial head will be out if the plastic deformation of the ulna is exceeded,it will break the ulna. Complications of this fracture are non-union, radiohumeral ankylosis, radioulnar synostosis and posterior interosseoz nevre or radial nerve palsy. Nerve palsy usually recovers spontaneously and rarely indicates exploration. In this article; we report a case of radial nerve entrapment caused by radial head compression after Monteggia fracture-dislocation and treated by external and internal microsurgical neurolysis in a 7 year-old girl patient.Öğe Posterior interosseous artery flap for severe hand injuries: Outcomes of reconstruction combined with local and regional flaps(Elsevier Ltd, 2026) Ertem, Hakan; Adıgüzel, İbrahim Faruk; Özdeş, Hüseyin Utku; Aslantürk, Okan; Ertem, KadirBackground Severe hand injuries with extensive soft-tissue loss present a significant reconstructive challenge. Achieving stable coverage while preserving hand function often necessitates the combined use of regional and local flaps. The posterior interosseous artery (PIA) flap, in combination with regional flaps harvested from non-salvageable digits, may offer an effective solution. Methods A retrospective analysis was performed on patients with severe hand injuries who underwent reconstruction using a PIA flap between 2022 and 2025. Patients were treated with either an isolated PIA flap or a PIA flap combined with local flaps, including fillet flaps harvested from non-salvageable digits or rotational flaps, depending on the extent and location of the defect. Demographic characteristics, injury mechanisms, defect locations, and surgical details were recorded. Postoperative complications and functional outcomes were assessed using fingertip-to-palm distance, Quick DASH score, and VAS for pain. Results Fourteen patients with severe hand injuries were included in the study. The mean age was 39.4 years, and the mean follow-up period was 19.7 months. Five patients with complex, multi-site defects underwent combined reconstruction using a PIA flap with local flaps (four with fillet flaps, one with a rotational flap), while nine patients were treated with an isolated PIA flap. Successful soft-tissue coverage was achieved in all patients without total flap loss. Partial distal flap necrosis occurred in two patients due to venous congestion and was managed with wound care followed by split-thickness skin grafting. At final follow-up, the mean fingertip-to-palm distance was 2.07 cm, the mean Quick DASH score was 21.89, and the mean VAS pain score was 2.07. All patients achieved stable wound healing and were able to perform daily activities without the need for further reconstructive procedures. Conclusion The PIA flap, either alone or in combination with local flaps, provides reliable soft-tissue coverage and favorable functional outcomes in patients with severe hand injuries. Combined reconstruction strategies should be considered based on defect characteristics, with acceptable complication rates and good functional recovery. This technique represents a valuable option in complex hand trauma reconstruction.

Materials and Methods: A hundred (56 female, 44 male) first year medical students were included in our study. A vitamin D screening form, which included 16 questions, was used to obtain data regarding medical students’ genetic, nutrition and cultural life. Results: Out of 100 medical students, 25 hydroxyl vit- D3 levels was below 5 ng/ml in 10%, 5-10 ng/ml in 10%, 10-20 ng/ml in 30%, 20-30 ng/ml in 40% and above 30 ng/ml in 10% medical students. While it has been found out that urbanization causes vitamin D deficiency and insufficiency in both females and males by negatively affecting sunlight exposure and nutrition, females have less sunlight exposure and their vitamin D levels are lesser when compared with males. Conclusions: In conclusion, urbanization decreases exposure to sunlight and changes nutritional habits and forms a basis for vitamin D deficiency. So, this shows that lack of vitamin D, which is a major cause of bone fractures in older ages, is actually mainly seen in younger ages.
