Acta Chir Orthop Traumatol Cech. 2024; 91(6):317-324 | DOI: 10.55095/achot2024/049 
Purpose of the study: The preclinical study aimed to compare the healing of segmental bone defects treated with biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel with the established autologous spongioplasty. Another aim was to evaluate the hydrogel as a scaffold for osteoinductive growth factor of bone morphogenetic protein-2 (BMP-2) and stem cells. Material and methods: The study was conducted in an in vivo animal model. A standardized rabbit model of a 15 mm long segmental bone defect of left radius was used. A total of 40 animals were divided into 5 groups of 8 individuals. In the KO- (negative control) group,...

Acta Chir Orthop Traumatol Cech. 2024; 91(6):325-330 | DOI: 10.55095/achot2024/046
Purpose of the study: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR). Material and Methods: The study included 47 patients treated at the Department of Paediatric Surgery, Orthopaedics and Traumatology...

Acta Chir Orthop Traumatol Cech. 2024; 91(6):331-338 | DOI: 10.55095/achot2024/067
Purpose of the Study Hand enchondromas are benign cartilage bone tumors. Curettage represents the actual gold standard for hand enchondromas. Little has been written about the effectiveness of curettage on hand functionality. Material and Methods In this retrospective study, we evaluated the effectiveness of curettage and bone grafting on the hand. For each case, we compared the pre-operative and post-operative QuickDASH of the treated limb. The final functional outcome was also evaluated by calculating the affected finger's Total Active Movement (TAM). Complications and local recurrences were recorded. Results Forty-five cases were included in our...

Acta Chir Orthop Traumatol Cech. 2024; 91(6):339-347 | DOI: 10.55095/achot2024/044
PURPOSE OF THE STUDY Intraarticular fractures of the distal femur rank among the most severe musculoskeletal injuries. Various treatment options, such as plate osteosynthesis or retrograde nailing, can be employed. This study aims to evaluate the clinical outcomes and complications of intraarticular distal femoral fractures treated with retrograde femoral nail, with particular emphasis on C3 fractures. MATERIAL AND METHODS Between January 2016 and January 2023, 18 AO/33.C3 fractures were treated with a retrograde femoral nail. Of these, two were classified as 33.C1, eight as 33.C2 and eight as 33.C3. Twelve of the fractures were open. After the initial...

Acta Chir Orthop Traumatol Cech. 2024; 91(6):348-354 | DOI: 10.55095/achot2024/048
Purpose of the study:Cognitive disorders are common in geriatric surgical patients We conducted a study to evaluate depression and cognitive behavior in geriatric patients undergoing orthopedic surgery. Material and Methods:This descriptive cross-sectional study was conducted at a university hospital in Turkey, involving 262 elderly patients who underwent orthopedic surgeries. Data were collected using The Patient Information Form, Standardized Mini-Mental Test, and Geriatric Depression Scale. Results:The mean score of the Standardized Mini-Mental Test scale of the patients after surgery was 17.97±4.99, mean score...
O-arm Versus C-arm: Comparison of the Learning Curves and Accuracy in Transpedicular Screw Fixation of Lumbar Spondylolisthesis
J. JABLONSKÝ, ©. TRNKA, P. STEJSKAL, L. HRABÁLEK, T. WANEK, M. VAVERKA
Acta Chir Orthop Traumatol Cech. 2024; 91(6):355-363 | DOI: 10.55095/achot2024/057
Purpose of the study The annual number of spinal fusion procedures has been increasing and is well documented worldwide. The O-arm is slowly becoming the standard for transpedicular screw insertion. The accuracy and safety of this method have been confirmed by many studies. Therefore, the learning curve of this method and its use by younger surgeons is the focus of our investigation. Longer operative time and radiation exposure to the patient are its only disadvantages. Our aim was to evaluate the learning curve of neurosurgical residents receiving specialist training and to demonstrate the safety and accuracy compared to the conventional C-arm-guided...
Is Extensor Indicis Proprius Tendon Transfer an Innocent Surgical Procedure for the Restoration of Extensor Pollicis Longus Function?

Acta Chir Orthop Traumatol Cech. 2024; 91(6):364-368 | DOI: 10.55095/achot2024/039
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....

Acta Chir Orthop Traumatol Cech. 2024; 91(6):369-375 | DOI: 10.55095/achot2024/037
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...

Acta Chir Orthop Traumatol Cech. 2024; 91(6):376-384 | DOI: 10.55095/achot2024/042
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...
