Öğe Achilles tendon-splitting approach and double-row suture anchor repair for haglund syndrome(Elsevier, 2021) Güler, Yasin; Birinci, Murat; Hakyemez, Ömer Serdar; Büyükdoğan, Kadir; Çaçan, Mehmet Akif; Arslanoğlu, Fatih; Mermerkaya, Musa UğurBackground: Haglund syndrom is characterized as a painful posterosuperior deformity of the heel with possible causes as tight Achilles tendon, high-arched foot and tendency to walk on the outside of the heel. Surgical treatment may be recommended in cases where of insufficient response to nonoperative treatment. This study aims to evaluate the clinical and radiographic results of central Achilles tendon splitting and double-row suture anchor technique in the surgical treatment of patients with Haglund syndrome. Methods: 27 patients with Haglund syndrome who underwent central Achilles tendon splitting and double-row suture anchor were retrospectively evaluated. The results were evaluated by the pre- and post-operative American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and visual analogue scale (VAS). All patients were evaluated radiographically to assess lateral talus-first metatarsal angle (TMTA), Calcaneal pitch angle (CPA), and the Fowler-Philip angle (FPA) preoperatively and postoperatively. Results: The mean preoperative AOFAS score was 47 +/- 7 points; at the end of the follow-up period, it increased to 92 +/- 4 points (p < 0.001). The mean preoperative VAS score was 9 +/- 0.9 points; at the end of the follow-up period, it was 2 +/- 0.6 points (p < 0.001). The lateral TMTA (preoperative: 5 degrees +/- 2 degrees; follow-up: 4 degrees +/- 2 degrees; p < 0.001), CPA (preoperative: 21 degrees +/- 5 degrees; follow-up: 20 degrees +/- 5 degrees; p = 0.005) and FPA (preoperative: 55 degrees +/- 6 degrees; follow-up: 32 degrees +/- 3 degrees; p < 0.001) values decreased at the end of the follow-up period. Conclusion: In the absence of an improvement to nonoperative treatment methods, central Achilles tendon-splitting approach appears to be an effective and safe treatment option. Level of evidence: Level IV, retrospective case series.Öğe Acute carpal tunnel syndrome caused by tenosynovial effusion due to calcium pyrophosphate deposition(Turkish Society for Surgery of the Hand and Upper Exremity, 2021) Birinci, Murat; Bostancı, Bilal; Çatal, BilgehanAcute carpal tunnel syndrome mostly occurs secondary to trauma. While storage diseases may cause symptoms of progressive nerve compression on a chronic basis, in some cases, they may present with acute onset symptoms. 77 years old female patient without known history of any rheumatic and chronic diseases was admitted to our clinic with pain and numbness. After physical examination and further interventions, surgery was performed with a pre-diagnosis of acute carpal tunnel syndrome. The patient was referred to the rheumatology department when the pathological examination of the samples taken during surgery was consistent with pseudogout.Öğe Acute carpal tunnel syndrome secondary to amyloidosis(Hindawi, 2019) Hakyemez, Ömer Serdar; Arslanoğlu, Fatih; Birinci, Murat; Çaçan, Mehmet Akif; Kara, AdnanIntroduction. ACTS secondary to amyloidosis is a very rare situation in the literature, and here, we present a unique case of ACTS secondary to amyloidosis. Case Report. A 61-year-old male patient was admitted to our hospital with complaints of numbness in the lateral half of his 1, 2, 3, and 4 fingers of his right hand. These complaints started acutely, and the patient did not have a history of trauma. His clinical examination was suitable for acute carpal tunnel syndrome. Discussion. Carpal tunnel syndrome, as well as acute carpal tunnel syndrome, may occur based on different causes. ACTS is very rare, especially when it is not caused by a trauma. Here, we presented a unique case of ACTS based on amyloidosis. Conclusion. It should be kept in mind when ACTS may occur in patients with the diagnosis of amyloidosis.Öğe Comparison of Hemiarthroplasty, total hip arthroplasty, and internal fixation for hip fractures in patients over eighty years of age: factors affecting mortality: a nationwide cohort study of fifty three thousand, four hundred and ninety five patients from Türkiye(2025) Uzel, Kadir; Birinci, Murat; Hakyemez, Ömer Serdar; Bostancı, Bilal; Bingöl, İzzet; Öktem, Umut; Azboy, İbrahimPurpose: Hip fractures are a common cause of mortality in elderly patients. This study aimed to determine the predictive factors affecting mortality among patients over the age of 80 who underwent surgical treatment for hip fractures. Methods: We searched the Turkish Ministry of Health’s e-health database to identify patients over 80 years old who had undergone surgery for proximal femoral fractures from 2016 to 2022. This process yielded 53,495 patients. Demographic data as well as comorbidities, blood transfusions, postoperative 90 days medical complications, and mortality was investigated. Multivariate logistic regression analysis was performed to identify risk factors for one year mortality in patients undergoing surgical treatment for proximal hip fractures. Results: The mortality rate was 37.2% in the first year. The mean Charlson comorbidity index(CCI) was 6.8 (range: 4–22). In the postoperative period, 68.6% of the patients received blood transfusions. Logistic regression analysis identified significant predictors of one-year mortality in surgical patients, including male gender, increased age, higher CCI scores, AKI, PE, pneumonia, electrolyte imbalance, gastrointestinal bleeding, blood transfusion, and increased mortality risks with hemiarthroplasty and internal fixation compared to total hip arthroplasty. (p < 0.001 for all). Conclusions: This large cohort study demonstrated that the mortality rate is high and that the type of surgery, male gender, older age, blood transfusion requirements, and high CCI score are associated with mortality in patients over 80 years of age who have undergone surgery for hip fractures. Preoperative optimization and postoperative care are critical for these vulnerable elderly patients.Öğe Editorial commentary: Anatomic or not, the tunnel will get wider!(W.B. Saunders, 2020) Mermerkaya, Musa Uğur; Büyükdoğan, Kadir; Hakyemez, Ömer Serdar; Birinci, Murat; Avcı, Cem CoşkunIn our experience, arthroscopic tunnel widening is one of the major complications after anterior cruciate ligament (ACL) reconstruction. Even though this complication doesn't require an acute correction or intervention, patients with failed ACL reconstruction along with tunnel widening may need a 2-stage revision in which we have to fill the gap in the tunnels first. Otherwise, this tunnel widening after ACL reconstruction doesn't affect the clinical outcomes of the primary surgery and it won't affect the success of the surgery in the aspects of clinical and functional outcomes.Öğe Effect of vitamin d deficiency on periprosthetic joint infection and complications after primary total joint arthroplasty(2024) Birinci, Murat; Hakyemez, Ömer Serdar; Geçkalan, Muhammed Ali; Mutlu, Müren; Yıldız, Fatih; Bilgen, Ömer Faruk; Azboy, İbrahimIntroduction: Vitamin D deficiency is a global problem, and 13 to 75% of patients undergoing total joint arthroplasty (TJA) have vitamin D deficiency. Several studies have shown that low preoperative vitamin D levels may increase the risk of postoperative complications, including periprosthetic joint infection (PJI), in patients undergoing primary TJA. However, most of the studies are underpowered. This study aimed to investigate the relationship between vitamin D deficiency and surgical and medical complications after primary TJA, with a specific focus on PJI. Methods: Prospectively collected institutional multicenter arthroplasty databases were reviewed to identify patients who underwent primary total knee and hip arthroplasty between 2019 and 2022. The study group was defined as patients whose vitamin D level is < 30 ng/dl and who received a single oral dose of 7.5 mg (300,000 IU) D3 within two weeks before index surgery (n = 488; mean age 63 years). Patients in the control group were those whose preoperative vitamin D levels were unknown and who did not receive vitamin D supplementation (n = 592, mean age 66). Demographics, comorbidities, and 90-day postoperative surgical and medical complications were recorded. The groups were compared regarding 90-day medical and surgical complications, including PJI, mortality, and readmission rates.Results: The total number of complications (8.6 and 4.3%; respectively; P = 0.005), superficial wound infection (2.5 and 0.2%, respectively; P < 0.001), and postoperative cellulitis (2.2 and 0% respectively; P < 0.001) were statistically significantly higher in the patient group who did not receive vitamin D supplementation. However, 90-day mortality (P = 0.524), PJI (P = 0.23), and readmission rate (P = 0.683) were similar between the groups. Conclusion: This study demonstrated that preoperative optimization of vitamin D levels may be beneficial in reducing postoperative complications, including superficial wound infection and postoperative cellulitis. Administering an oral 300,000 U single-dose vitamin D regimen to correct vitamin D deficiency can positively impact outcomes following primary TJA.Öğe Epidemiology, treatment, and mortality of femoral neck fractures in patients over the age of 65 years: a nationwide retrospective cohort study of 83,789 cases in Turkey(2025) Demirel, Mehmet; Birinci, Murat; Hakyemez, Ömer Serdar; Azboy, Nesrullah; Bingöl, İzzet; Azboy, İbrahim; Şen, CengizBackground: A population-based study delineating the epidemiologic, clinical, and treatment characteristics of femoral neck fractures (FNFs) in elderly patients has not yet been conducted in Turkey. In this nationwide study, the epidemiologic, clinical, and treatment characteristics of patients aged ⩾65 years with FNFs who underwent osteosynthesis, hemiarthroplasty (HA), or total hip arthroplasty (THA) were examined. Methods: Patients aged ⩾65 years with FNFs were identified in this retrospective, nationwide study. Then, the patients who underwent osteosynthesis or total/hemiarthroplasty from 2016 to 2021 were included. All the outcome variables were collected from patient medical records stored in the e-health database of the Republic of Turkey Ministry of Health. Results: A total of 83,789 FNFs treated surgically were analysed. Osteosynthesis was performed on 21,130 FNFs (25.2%), HA on 56,378 FNFs (67.3%), and THA on 6281 FNFs (7.5%). From 2016 to 2021, the overall revision rates for THA and HA were 14.6% (914/5367 patients) and 5.9% (3301/53,077 patients), respectively. The rate of revision prosthetic surgery was significantly higher after THA than after HA (p < 0.001). Mortality rates at 1 year were 25% (n = 5293) for osteosynthesis, 14.7% (n = 924) for THA, and 71.1% (n = 40,109) for HA (p = 0.001). The multivariate model of 1-year postoperative mortality revealed 7 independent predictors: male sex (odds ratio [OR] 1.694; 95% confidence interval [CI], 1.640–1.751), use of a cemented femoral stem (OR 1.182; 95% CI, 1.117–1.250), acute myocardial infarction (AMI) (OR 1.317; 95% CI, 1.240–1.400), cerebrovascular accident (CVA) (OR 1.379; 95% CI, 1.333–1.425), chronic liver disease (CLD) (OR 2.188; 95% CI, 1.802–2.489), diabetes mellitus (DM) (OR, 1.160; 95% CI, 1.122–1.200), and age >81.50 years (OR 2.654; 95% CI, 2.569–2.742). Conclusions: Our study suggested that a hemiarthroplasty is the most common treatment modality for FNF followed by osteosynthesis (25.2%) and THA (7.5%) in Turkey. Revision rates after THA for FNF are concerning. The 1-year mortality rates are highest after HA, followed by osteosynthesis and THA. Male sex, cemented fixation, CVA, CLD, liver failure, DM, and age >81.50 are the independent predictive factors for postoperative 1-year mortality in this specific group of patients.Öğe Is shoulder geometry important for rotator cuff tears?(John Wiley and Sons Inc, 2021) Yılmaztürk, Kerem; Birinci, Murat; Kuyucu, Ersin; Bülbül, Ahmet MuratPurpose This study is aiming to evaluate some specific anatomic shoulder parameters such as the lateral acromial angle (LAA), acromial index (AI), coracohumeral distance (CHD) and critical shoulder angle (CSA) in rotator cuff tears. Methods A total of 100 cases consisting of 50 patients with rotator cuff tears and 50 patients without rotator cuff tears, who underwent shoulder MRI (mangnetic resonance imaging) examination in Istanbul Medipol University Orthopedics and Traumatology Department, participated in this study. In this retrospective study, CCA, LAA, AI and CSA were evaluated in MRI in order to shed light on the theories of rotator cuff tears. Results There was no significant difference (P > .05) in acromial index and coracohumeral distance in the patient group. Lateral acromial angle and critical shoulder angle were significantly different in the patient group compared to the control group (P < .05). There was a weak negative correlation between CSA and CHD. Conclusion In our study, we found that patients with smaller LAA and higher CSA values in MRI images are prone to have rotator cuff tears. Further studies are needed in order to evaluate whether this association has predictive value.Öğe Posterior vertebral column resection: Exploring practical uses in clinical settings(2024) Çaçan, Mehmet Akif; Birinci, Murat; Mertsoy, Yılmaz; Uzel, Kadir; Bostancı, Bilal; Uçar, Bekir YavuzBackground: The purpose of this study was to present our experience in patients who had been treated with posterior vertebral column resection (PVCR) for various spinal deformities. Methods: Thirty-seven patients who performed PVCR between 2015 and 2018 were evaluated retrospectively. The mean follow-up period was 24 months (range: 12-50 months). The demographic data of the patients, mean blood loss, amount of blood replacement, duration of operation, intensive care and hospitalization period, PVCR level, instrumentation level, amount of preoperative curvature, amount of postoperative curvature improvement, preoperative and postoperative neurological status, and complications were examined. Angular measurements were performed on X-ray. Results: The mean age of the patients was 37.5 years (range: 3-80 years). PVCR was applied to patients due to different pathologies (congenital, tumor metastasis, posttraumatic kyphosis, revision scoliosis, and infection). The mean operation time was 445.5 min (260-720) with an average blood loss of 1903 ml (400-7000 ml). It was observed that the average local kyphosis angle decreased from 67.65° to 7.42° in 26 patients who were operated for advanced deformity (P < 0.001). When these values were compared in all 34 patients, the preoperative angle value decreased from 55.1° to 3.5° (P < 0.001) and decreased from 70° to 0° in 13 congenital kyphosis patients. Conclusion: PVCR is an effective method for correcting severe spinal deformities and can be used to correct curvature in different patient groups. Level of Evidence: Level 3.Öğe Predictive value of different glycemic control markers in total hip or knee arthroplasty: A prospective study(AVES, 2023) Çetik, Rıza Mert; Azboy, İbrahim; Birinci, Murat; Öztürkmen, Yusuf; Kalyenci, Ahmet Sinan; Atilla, BülentObjective: The optimal glycemic control marker before total hip or knee arthroplasty remains inconclusive. Hemoglobin A1c (HbA1c) is widely used, while fructosamine may be valuable for predicting periprosthetic joint infection (PJI). Fructosamine levels can be affected by serum albumin levels; albumin-corrected fructosamine (AlbF) can be calculated to overcome this issue. The objective of this study was to evaluate the predictive value of different markers for complications after primary total hip or knee arthroplasty. Methods: This prospective cohort study included 304 patients (mean age: 65 years [range, 16-85), mean follow-up: 32 months (range, 12-49)] who underwent primary total hip or knee arthroplasty between 2018 and 2021. Of them, 156 patients had diabetes. Mean HbA1c was 6.5% (range, 4.8%-13%), fructosamine 244 µmol/L (range, 98-566 µmol/L), and AlbF 632 (range, 238-2308). Patients who did and did not have diabetes were matched 1: 1. Hemoglobin A1c 7% and fructosamine 292 µmol/L were used as cutoff. Complications were documented. Glycemic markers were compared using logistic regression analyses, with a special focus on PJI. Results: In the logistic regression analyses, HbA1c was strongly associated with total complications [adjusted odds ratio (OR): 3.61; 95% CI, 1.65-7.91, P = .001], while fructosamine was associated with PJI (adjusted OR: 13.68; 95% CI, 1.39-134.89, P = .025). Albumin-corrected fructosamine did not show any additional benefits. Conclusion: Preoperative assessment before total hip or knee arthroplasty must not focus on a single marker; HbA1c is a good predictor of total complications, while fructosamine is a better predictor of PJI. To the best of our knowledge, in its first orthopedic study, AlbF did not show any advantages. Level of Evidence: Level II, Prognostic Study.Öğe Proximal tibiofibular joint arthrodesis due to recurrent giant ganglion cyst causing peroneal nerve palsy(Cureus Inc, 2023) Birinci, Murat; Korkmaz, Oğuzhan; Bostancı, Bilal; Örmeci, Tuğrul; Kara, AdnanGanglion cysts are masses that we encounter frequently in our daily practice, usually in the upper extremity, less frequently in the lower extremities, and rarely cause compression symptoms. We present a case of a massive ganglion cyst of the lower limb causing peroneal nerve compression, managed with excision and proximal tibiofibular joint arthrodesis to prevent recurrence.Examination and radiological imaging of a 45-year-old female patient who was admitted to our clinic showed new-onset weakness in right foot movements and numbness on the dorsum of the foot and lateral cruris, a mass consistent with a ganglion cyst expanding the muscle was detected in the peroneus longus muscle. In the first surgery, the cyst was carefully resected. After three months, the patient came with a repeated mass on the lateral side of the knee. After confirmation of the ganglion cyst with clinical examination and MRI, a second surgery was planned for the patient. In this stage, we performed a proximal tibiofibular arthrodesis for the patient. Her symptoms recovered during the early follow-up period and no recurrence occurred during the two years of the follow-up period.Although the treatment of ganglion cysts seems easy, it can sometimes be challenging. We think that arthrodesis may be a good treatment option in recurrent cases.Öğe Sonar mining of deeply located foreign bodies in the musculoskeletal system(2024) Çaçan, Mehmet Akif; Birinci, Murat; Uzel, Kadir; Yılmaz, Mehmet Kürşat; Kemah, Bahattin; Tuğrul, Ali İhsanIntroduction: Foreign body (FB) injuries constitute an important part of admission to emergency and orthopedic clinics in daily practice. The localization and removal of FBs can be difficult. Ultrasound (USG) plays an important role in the localization of FBs. In this study, we aimed to present the results of patients who underwent US-guided FB extraction. Methods: Fifty-seven patients who were admitted to the emergency service and orthopedic outpatient clinic due to FB trauma to soft tissue were retrospectively evaluated. USG-guided removal was performed under local anesthesia. The number, size, shape, structure, distance to the skin, and integrity of the FB were determined using USG guidance. Patient satisfaction was evaluated with Results: The mean duration of surgery was 7 min (range; 5 to 20 minutes), and the mean incision size was 11 mm (range; 5 to 25 mm). Forty-seven of the patients underwent an outpatient procedure and were discharged on the same day. No postoperative complications were observed. Fifty one of 57 (89.5%) were very satisfied with the surgery. Conclusion: Consequently, USG-guided FB extraction is a safe, fast, and comfortable option for the patient and the physician. Orthopedic physicians should receive USG training starting from their assistantship, and its use in daily practice should be increased.Öğe The use of external fixator and iliac crest bone graft in traumatic metacarpal bone defect(Maharashtra, India, 2022) Korkmaz, Oğuzhan; Abourdan, Joud; Birinci, Murat; Bostancı, Bilal; Kara, AdnanIntroduction: Metacarpal bone fractures often lead to significant shortening in the phalanges; it can be caused by variable conditions, ranging from idiopathic, and infective to traumatic causes. There are very rare reports of metacarpals shortening in idiopathic primary hypoparathyroidism cases in the literature. Traumatic metacarpal shortening differs from congenital agenesis [2]. This condition leads to both functional and cosmetic limitations which affect the patient's quality of life. Case report: A 22-year-old male patient was admitted to our outpatient clinic with a traumatic left-hand fracture that caused a bone defect in the second metacarpal shaft leading to bone loss, shortening and flexion limitation in the second finger of the left hand, and a flexion contracture in the first metacarpophalangeal joint. For the treatment plan, an external fixator was set on the second metacarpal of the left hand for a 23 mm elongation over a period of 58 days, elongation rate was organized as 1 mm/day. After achieving the planned elongation, another operation was planned for the reconstruction of the bone defect that has occurred due to trauma in the second metacarpal bone. An osteotomy was performed for extracting an iliac crest graft and inserting it into the bone defect after debridement of scar tissue. For the first metacarpophalangeal joint, an arthrodesis was performed through the use of plate and screws. Multiple studies have showed a common complication of pin tract infections, which were controlled with oral antibiotics and local wound care [10, 11]. Proper alignment and union were achieved with early, stable fracture fixation of low-velocity gunshot wounds of the metacarpal. With early rehabilitation, treatment was provided without an increase in morbidity. [11]. Conclusion: It is possible to obtain acceptable surgical results when the method of fixation of the defect with autograft is used after lengthening with external fixator in pseudoarthrosis with metacarpal defect.Öğe Unseen threefold mortality after the first ten days in hemodialysis patients following joint arthroplasty: a nationwide retrospective cohort study of 1,287 arthroplasty patients on hemodialysis(2024) Birinci, Murat; Hakyemez, Ömer Serdar; Korkmaz, Oğuzhan; Bingöl, İzzet; Ata, Naim; Ülgü, Mahir Mustafa; Birinci, Şuayip; Ayvalı, Mustafa O.; Başarır, Kerem; Azboy, İbrahimBackground: The study addresses the growing number of hemodialysis (HD) patients undergoing joint arthroplasty, who are at higher risk of complications and mortality. Previous research has often overlooked deaths after discharge. This study aimed to examine early outcomes in a large nationwide cohort of patients who underwent arthroplasty for elective and fracture-related reasons. Methods: Between 2016 and 2022, a study was conducted using the e-Nabız database of the Türkiye Ministry of Health, focusing on patients aged 18 years and above who underwent elective or fracture-related arthroplasty. This study included 1,287 patients reliant on dialysis who underwent total hip arthroplasty, total knee arthroplasty, or hemiarthroplasty (HA), with 7.7% of them receiving dialysis for the first time. Propensity score matching was used to create an equally sized group of non-dialysis-dependent patients, ensuring demographic balance in terms of age, sex, a comorbidity index, and surgery type. The primary objective was to compare mortality rates 10, 30, and 90 days after arthroplasty. Results: The first-time dialysis patients who underwent HA had significantly higher 30- and 90-day mortality rates compared to the chronic dialysis group (P = .040 and P < .001, respectively). Also, the HD patients consistently exhibited higher 90-day mortality rates across all surgery types. With total knee arthroplasty, HD patients had a mortality rate of 8.7%, in stark contrast to 0% among non-HD patients (P < .001). Similarly, with total hip arthroplasty, HD patients had a 12% mortality rate, while non-HD patients had a markedly lower rate of 2.7% (P = .008). In the case of HA, HD patients had a significantly elevated 90-day mortality rate of 31.9%, in contrast to 17.1% among non-HD patients (P < .001). Conclusions: Joint arthroplasty has higher rates of mortality and complications among HD patients. Surgical decisions must be based on patients’ overall health, necessitating collaboration among specialists. These patients should be closely monitored.
