(Türk Travma ve Acil Cerrahi Derneği, 2019-07-02) Bilekdemir, Utku; Civan, Osman; Özdemir, Hakan; Cavit, Ali; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; AAK-9223-2020; 55507113700
BACKGROUND: This study aims to evaluate the surgical approaches, complications, clinical and radiological findings in acetabular fractures treated with surgical methods and to determine the parameters affecting prognosis.METHODS: Out of 144 patients undergone surgical treatment with the diagnosis of displaced acetabular fractures between 1994 and 2014, a total of 103 patients with 75 male and 28 female with a mean age of 36.3 years (range 19-67 years) whom clinical and radiologic follow-ups (mean: 34 months, range 2-8 years) were performed at least for two years were included in this study.RESULTS: Clinically excellent to good outcomes were obtained in 64% of the patients and moderate to poor outcomes were recorded in 36% of the patients, while radiologically excellent to good outcomes were achieved in 57.3% of the patients and moderate to poor outcomes were recorded in 42.7% of the patients. Presence of one of the complications, creating mechanical block (chi-square p<0.001), complex fractures (chi-square p=0.023), increased duration between trauma and operation (p=0.039), operational time taking longer than six hours (chi-square p<0.001), more than 3 mm intra-articular step (Fisher's p=0.033), avascular necrosis (p<0.001), arthritis (p=0.006) and heterotopic ossification (p=0.007) worsened the clinical outcomes (chi-square p<0.001). The age of the patient was not effective on the clinical outcome (p=0.461).CONCLUSION: It was found that three major parameters affecting the prognosis of acetabular fractures are as follows: type of fracture, operational time and reduction quality. The duration between trauma and operation indirectly affects the outcomes. Avascular necrosis, heterotopic ossification and arthritis may cause negative effects only on long term outcomes.

(Thieme Verlag, 2020-04-29) Civan, Osman; Güntürk, Özgün Barış; Özaksar, Kemal; Özcanlı, Haluk; Cavit, Ali; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; FZU-6956-2022; 55507113700
PurposeGlomus tumors are rare vascular pathologies characterized by a triad of symptoms: tenderness, pain and cold intolerance. In the hand they are highly concentrated under the nail bed. In this retrospective study, we aimed to present a topographic map of the location of glomus tumors in the nail bed and a map-based surgical approach algorithm to the subungual glomus tumors. MethodsWe prepared a nail bed map with 6 zones and named these zones as ulnar distal, ulnar proximal, central distal, central proximal, radial distal and radial proximal. With respect to the tumor location and the used surgical approach we retrospectively evaluated the intraoperative photos and the hospital records of patients who were operated between 2008-2019 and had the pathological diagnosis of glomus tumor. The examination records of the postoperative first year were evaluated for each patient retrospectively. A descriptive statistical analysis was performed. In addition we analyzed the described surgical approaches to excise a glomus tumor in the nail bed. The described approaches and the approaches used by us were matched with the localisation of the tumors in this study developing an algorithm for the surgical approach depending on the localisation of the nail bed glomus tumor. ResultsFinally 44 patients had inclusion criteria. The distribution of the glomus tumor was as follows: 2 were on ulnar distal (4.5 %), 9 on ulnar proximal (20.5 %), 1 on central distal (2.3 %), 18 on central proximal (40.9 %), 4 on radial distal (9.1 %) and 10 were on the radial proximal zones (22.7 %). 4 lateral approaches, 1 nail sparing and 39 transungual approaches were performed. We had one recurrence in a male patient operated by transungual approach. ConclusionGlomus tumors are mostly located on the central proximal part of the nail bed. Our glomus map and the algorithm we described might be helpful for the selection of the surgical approach for the glomus tumor.

(Türkiye Eklem Hastalıkları Tedavi Vakfı, 2020-06-18) Civan, Osman; Alimoğlu, Bahadır; İçen, Mustafa; Taşkın, Selim; Söyüncü, Yetkin; Ürgüden, Mustafa; Cavit, Ali; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı.; 55507113700
Objectives: This study aims to investigate the effects of associated factors like age, fracture level, accompanying fibular fractures and wound condition on healing by determining and comparing union scores of pediatric tibial fractures (PTFs). Patients and methods: Forty-five patients with 46 PTFs (32 males. 13 females: mean age 9.5 years: range 2 to 16 years) who were treated by closed reduction and casting or operated between January 2016 and January 2019 were retrospectively evaluated. The union scores were evaluated at the end of fourth. sixth and eighth weeks and compared to each other. Effects of the age, associated fibular fractures. wound condition. fracture level and treatment type to union score were analyzed. Results: Twenty-eight (60.9%) out of 46 PTFs had associated fibular fractures and 18 (39.1%) did not. Motor vehicle accident was the most frequent etiologic factor (47.8%). Thirty-four out of 46 fractures were closed tibial fractures (73.9%) and 12 had open wound (26.1%). There was a negative correlation between age and the union scores (p<0.001 for each week). No significant difference was observed between the union score of diaphyseal and metaphyseal fractures at the fourth. sixth. and eighth weeks. The union scores of each week were higher in the conservative group compared to operative group (p<0.001 for each week). Associated fibular fracture group had lower union scores compared to isolated tibial fracture group at fourth. sixth and eighth weeks. Likewise, the union scores of the open fracture group were lower than the closed fracture group (p<0.05 for each week). Conclusion: Associated fibular fractures, open fractures and aging negatively affect union scores of PTFs. Attention should be paid. particularly in these conditions. during the selection of the operation type and the follow-up period of PTFs.

(Sage Publications, 2019-03-01) Ürgüden, Mustafa; Gülten, İsmail Ayder; Civan, Osman; Bilbasar, Hakan; Kaptan, Cağrı; Cavit, Ali; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0003-0216-1169; 0000-0002-4839-1747; IAQ-9614-2023; AAK-9223-2020
Background: The aim of this study was to evaluate the role of tendoscopy in the diagnosis and treatment of peroneal tendon (PT) pathologies, and to evaluate the results of our technical modification. Methods: Twenty ankles of 18 patients with retrofibular pain, operated on between 2006 and 2012, were included in this study. Peroneal tendoscopy was performed diagnostically for the patients who were diagnosed as having "peroneal tendinopathy" with physical examination, x-ray, or magnetic resonance imaging (MRI). After being diagnosed by peroneal tendoscopy, patients were definitively treated with either tendoscopy or open surgery. Results: Thirteen of 20 ankles had accompanying ankle pathology with PT pathology, and the other 7 ankles had no concomitant pathology. We detected peroneal tenosynovitis (PTS) in 13 patients, PT tear in 7 patients, and vincula thickening in 1 patient. The American Orthopaedic Foot & Ankle Society (AOFAS) score was 76 preoperatively, and after 2 years' follow-up the AOFAS score was 96. Conclusion: Tendoscopy is a useful method for the diagnosis and treatment of PT pathologies. The patients with clinical suspicion of PT pathology were treated or diagnosed by peroneal tendoscopy with our technical modifi
Tenolysis rate after zone 2 flexor tendon repairs
(Türk Eklem Hastalıkları Vakfı, 2020-01-01) Civan, Osman; Gürsoy, M. Kemal; Cavit, Ali; Özcanlı, Haluk; Karalezli, M. Nazim; Cavit, Ali; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi Anabilim; 0000-0002-4839-1747; FZU-6956-2022
Objectives: This study aims to evaluate the tenolysis rates of zone 2 flexor digitorum profundus (FDP) with flexor digitorum superficialis (FDS) tendon repairs using four -strand technique and early passive motion exercises. Patients and methods: In this retrospective study, we performed zone 2 flexor tendon repairs in 149 patients (117 males, 32 females, mean age 33.3?12.9 years; range, 13 to 72 years) (82 right and 67 left hands) between November 2014 and January 2019. A total of 194 FDP and FDS tendons were repaired primarily by using modified Kessler and Bunnell methods. Patients underwent pure passive motion protocols after surgery according to modified Duran?s protocol. No active flexion components were added until postoperative fourth week. Results: Twenty-three out of 149 patients and 28 out of 194 fingers (14.43%) had tenolysis. There was no significant relationship between the number of operated fingers, gender, and tenolysis rate (p=0.836, p=0.584, respectively). Conclusion: The repair of the FDP with FDS tendon increases the tenolysis rate in zone 2. The tenolysis rate does not change according to the number or distribution of injured fingers and gender of the patient.
