Purpose of the study: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy. This study evaluated the diagnostic accuracy and reliability of percutaneous core needle biopsy.

Material and methods: The study included the results of 250 percutaneous core needle biopsies of 244 patients who presented at the tertiary university hospital between September 2012 - September 2022 and were diagnosed with a bone or soft tissue tumor using the percutaneous core needle biopsy method and then underwent surgical excision in the Orthopaedics and Traumatology Clinic. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy rates were calculated for the percutaneous core needle biopsy method according to the compatibility of the results.

Results: A fluoroscopy-guided percutaneous Jamshidi needle biopsy performed by an orthopedist for lesions originating from the bone has a diagnostic accuracy of 96%. CT-guided percutaneous Jamshidi needle biopsy performed by a radiologist for lesions originating from the bone has a diagnostic accuracy of 88.9%. Percutaneous Tru-cut needle biopsy performed by an orthopedist without imaging guidance for lesions originating from soft tissue has a diagnostic accuracy of 92%. USGguided percutaneous Tru-cut needle biopsy performed by a radiologist for lesions originating from soft tissue has a diagnostic accuracy of 96,7% (p<0.001).

Discussion: The diagnostic accuracy of open biopsies ranges from 91% to 99% in the literature. Additionally, the diagnostic accuracy of core needle biopsies in recent studies ranges from 76% to 99%. Compared to the literature, our study has shown that biopsies performed by orthopedic specialists have a high diagnostic power (96% for bone-derived lesions; 92% for soft tissue-derived lesions).

Conclusions: Percutaneous core needle biopsy is highly effective and reliable in diagnosing bone and soft tissue tumors. Managing patients by a team using a multidisciplinary approach will increase diagnostic success.

Key words: core needle biopsy, percutaneous, diagnostic accuracy, radiology guided biopsy, bone and soft tissue tumors.

Purpose of the study: Lisfranc is a challenging injury both diagnostically and surgically, with sparse long-term literature evidence of surgical practice. We aim to review our long-term specialist orthopaedic institutional experience of Lisfranc injuries and the surgical management of this complex injury, specifically considering surgical outcomes as per radiological and clinical assessment.

Material and methods: We present data from a prospectively maintained institutional database, reviewing patients who underwent operative fixation for Lisfranc injury between April 2014 and August 2020. Patients were referred to our institution from hospitals across the country. We included all operatively managed Lisfranc injuries, primary procedures, and patients over the age of 16. Revision procedures, open injuries, polytrauma patients, patients under the age of 16, and those with multiple foot injuries were excluded. We assessed post-operative results as per the Wilpulla radiographic and clinical criteria.

Results: We treated 27 patients across the study period, of mean age 37.5 (SD 18.3), 55% male and 45% female. 33.3% of our patients were obese as defined by body mass index >30. As per the Myerson classification, we had 2 category A, 24 category B, and 1 category C injuries. Time to operation was median 14 days (range 0-116), with 2 delayed presentations following failure of conservative treatment. Our median length of stay was 1 day (range 0-16). We had 3 complications: 2 wound infections and 1 re-operation for non-union. Post-operative assessment as per Wilpulla demonstrated 74% of good, 18.5% fair and 7% poor fixation results.

Conclusions: In our institutional experience, partial congruity lateral displacement injuries were the majority of surgical referrals. Surgical treatment through open reduction and internal fixation delivers good clinical and radiographically anatomical results. Further to conventional mechanisms of injury, we propose obesity to be an important risk factor for indirect, low-energy injuries that may help identify this injury.

Key words: Lisfranc injury, long-term, orthopaedic surgery, obesity.

Proximal femur fractures (PFF) pose a major challenge in elderly patients with severe comorbidities and receiving antithrombotic therapy since according to the latest guidelines the surgery should be performed as soon as possible, preferably within 24 hours, to reduce mortality and morbidity. This review outlines the practical approach to surgical management of PFF that relies on increasing evidence of safety of early surgery in patients with PFF receiving antiplatelet and anticoagulant therapy. We have also used information from the existing evidence-based guidelines for elective/planned surgery in patients with antithrombotic therapy. The practical approach can be summarised as follows: • Antiplatelet therapy - discontinuation of acetylsalicylic acid (ASA) and clopidogrel in monotherapy or in combination is not necessary prior to surgery. In case of bleeding, antifibrinolytic therapy is recommended as well as administration of platelet concentrate which is rarely needed. • In patients taking warfarin, reversal of its effects is recommended by early administration of vitamin K to allow surgery to be performed within 24 hours. Prothrombin complex concentrate (PCC) as a second-line drug is reserved for extreme cases only. Warfarin therapy is resumed 24 hours after surgery. • Direct oral anticoagulants must be discontinued 24-48 hours prior to surgery, possibly longer depending on the type of drug, time of administration of the last dose, and renal function. In extreme cases, an antidote (idarucizumab, off-label andexanet) can be administered prior to surgery, or PCC in case they are unavailable. Anticoagulation therapy is resumed in 24-48 hours. • Neuraxial anaesthesia is possible when ASA is taken by the patient and in case of effective warfarin reversal. • In early surgery and rapid restart of anticoagulant therapy, bridging therapy with LMWH is not indicated except for in cases with extreme risk of thrombosis.

Purpose of the study: Laminectomy with fusion (LF) is commonly performed with laminoplasty (LP) for cervical myelopathy. Foraminal stenosis is important in the surgical treatment of cervical myelopathy. LF and LP can affect foraminal size in different ways. This study aimed to compare foraminal dimensions after LF and LP using a medical computer-assisted design (CAD) program.

Material and methods: Computed tomography (CT) scans of the cervical vertebrae of 16 patients with cervical myelopathy were retrospectively viewed in the Digital Imaging and Communications in Medicine format on a CAD program. CT images were reformatted in an oblique plane perpendicular to the long axis of each foramen from C2-C3 to C6-C7. The narrowest foraminal crosssectional dimension (FCD) was measured and compared between the LF and LP groups at the operated, non-operated, and C4-C5 levels. The difference between the preoperative and postoperative FCDs was also calculated and compared between the operated and C4-C5 levels. Intra- and interobserver reliabilities for FCD measurements were evaluated using intraclass correlation coefficients.

Results and discussion: At the operated spinal levels, the LF and LP groups showed decreased and increased mean FCDs, respectively. At the adjacent non-operated levels, the mean FCD slightly increased in both the groups. In the LF group, the difference between the preoperative and postoperative FCDs in the C4-C5 levels was larger than that in the other operated levels, but this difference was insignificant.

Conclusions: LF and LP showed contrary results for FCD. Therefore, FCD and kyphosis should be considered for LF and LP.

The bone transport technique uses the principle of distraction-osteogenesis and fill bone defects with the aid of an external fixator. In order to evaluate the clinical effect of femoral internal fixation with Ortho-Bridge System after bone transport, 4 patients after femoral bone transport from October 2020 to October 2022 are studied in this paper. Among them, 3 patients ran refracture of femur after removal of the Limb reconstruction system, 1 patient just finish femoral bone transport and request internal fixation. The surgery results show that Ortho-Bridge System can be used in the situation that conventional Locking compression plate and intramedullary nail are not suitable due to anatomical variation after femoral bone transport. Key words: femoral fracture; Ortho-Bridge System; bone transport; postoperative complications of bone transport.

Purpose of the study: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity.

Material and methods: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months. The extensor strengths were measured according to the Medical Research Council (MRC) scoring system. Nail tip-table surface distance (NTD) was measured to evaluate extension loss, and pulp-palm distance (PPD) to evaluate thumb flexion-adduction limitation. Grip and key pinch strengths were measured and corrected regarding the dominance and compared with those of the non-operated side. Quick Disability of Arm, Shoulder, and Hand (QDASH) and satisfaction scores of the patients were evaluated.

Results: Donor site morbidity was detected in 6 patients (35%). The extension strength of the index finger was found to be significantly lower than the non-operative side (p<0.05). Thumb mean NTD and PPD values were 6.8 (0-50) and 2.9 (0-20) mm, respectively. The index finger mean NTD was 0.6 (0-10) mm. The grip strength was 86% (43%-100%) and the pinch strength was 82% (31-100%) of the expected strengths. Compared to the preoperative period, there was a significant decrease in the QDASH score (p <0.05). Postoperative QDASH scores of patients with donor site morbidity were significantly higher than those without (p <0.05).

Conclusions: Although patients are generally satisfied with the EIP-EPL transfer results, the permanent morbidity rate in the index finger is high. Therefore, alternatives other than EIP should be considered for transfer to EPL in individuals whose occupation requires complete and strong index finger extension.

Purpose of the study: Simple bone cysts (SBCs) are the most common benign bone lesions in childhood. There are many different methods in the treatment of SBCs. There is no consensus on which method to use in the treatment. In this study, we compared the results of allogeneic bone graft or synthetic bone graft in addition to fl exible intramedullary nail (FIN) for SBC located in the humerus.

Material and methods: This retrospective study comparing the data of 19 (group 1: 8 curettage, allograft and FIN; group 2: 11 curettage, synthetic graft and FIN) patients with a mean age of 11.4 (6 to 26; seven female, twelve male) who were surgically treated in our hospital for humeral SBC between April 2014 and January 2020. Patient data included age, sex, anatomical side, stage of the cyst, pathological fracture, previous treatments and complications.

Results: The mean follow-up period was 33.7 months (12 to 61). The average last follow-up Musculoskeletal Tumor Society functional scores for groups 1 and 2 were 27.8 (20 to 30) and 28.6 (21 to 30) (P > 0.05). Complete or signifi cant partial radiographic healing rates were achieved in group 1 (75%) compared with group 2 (81.9%). The reoperation rates for groups 1 and 2 were 62.5% (5/8; three for nails removed, two for recurrence) and 36.3% (4/11; two for nails removed, two for recurrence). One patient in group 2 had a 15° varus deformity due to recurrence. No other complications were observed.

Conclusions: The combination of curettage-grafonage FIN is a common treatment method in recent years, as it provides early cyst healing and limb mobilization in SBCs located in the upper extremity. For defects after curettage of the bone cysts, allogeneic or synthetic grafts (granule b-tricalcium phospate) which have similar results in terms of healing can be used as an alternative to each other.

Purpose of the study: Our aim was to compare the effects of intraarticular and intravenous (IV) tranexemic acid (TXA) application on bleeding and complication rates in patients who underwent total knee arthroplasty (TKA).

Material and methods: Between 2017 and 2021, 406 patients who underwent TKA with 2 g of IV TXA and retrograde 1.5 g of TXA applied through the drain were included in the study. Of the patients, 206 were in the IV TXA group. Preoperative and postoperative hemoglobin levels, drain output, BMI, ASA score, blood loss, and the number of transfused patients were recorded. Complications such as symptomatic venous thromboembolism were also recorded.

Results: There was no significant difference between the two groups in terms of age, sex, American Society of Anesthesiologists (ASA) score, or BMI (p = 0.68, 0.54, 0.28, 0.45). Total drain output and blood loss were significantly higher in the IV TXA group than in the intraarticular TXA group (p < 0.0001, p < 0.0001). Eighteen patients in the IV TXA group and 1 patient in the intraarticular TXA group received a blood transfusion (p < 0.0001). There was no difference between the two groups in terms of preoperative hemoglobin or platelet count (p = 0.24). However, postoperative hemoglobin level was higher in the patients who received intraarticular TXA (p=0.0005). More thromboembolism events were seen in the IV TXA group (p < 0.0001).

Conclusions: Intraarticular TXA application reduces blood loss more than IV application, reduces the blood transfusion rate, and causes fewer complications.
