Acta Chir Orthop Traumatol Cech. 2026; 93(1):9-14 | DOI: 10.55095/achot2025/042  

Arthroscopy has evolved significantly with advancements in instrumentation and surgical techniques. The introduction of needle arthroscopy represents a promising minimally invasive alternative and, has for the wrist proven to offer a reduced soft tissue trauma with still maintained diagnostic and therapeutic efficacy. The purpose of this study was to evaluate the safety and visualization capabilities of needle arthroscopy of the elbow using cadaveric specimens. Six fresh-frozen cadaveric elbows (three right, three left) were examined using a needle arthroscope, followed by dissection to assess portal safety and proximity to neurovascular structures....

Acta Chir Orthop Traumatol Cech. 2026; 93(1):15-21 | DOI: 10.55095/achot2025/036  

To develop an anatomically verified protocol for ultrasound-guided analgesic interventions targeting the thoracolumbar fascia region for the treatment of both acute and chronic back pain. One cadaver was embalmed using the Fix-4-Life method, which preserves tissue properties suitable for subsequent ultrasound visualization. Under ultrasound guidance, a needle was inserted to the thoracolumbar fascia at the level of the transverse process of the fourth lumbar vertebra. Upon contact with the transverse process, 5 ml of diluted red latex dye was injected. The distribution of the injected fluid was then observed through anatomical dissection. This cadaveric...

Comparison of MRI of Paraspinal Muscles in Patients after Open and Minimally Invasive Percutaneous Stabilisation of Thoracic and Lumbar Spine Fractures

Acta Chir Orthop Traumatol Cech. 2026; 93(1):22-28 | DOI: 10.55095/achot2025/033  

Magnetic resonance imaging (MRI) was used to evaluate paraspinal muscle damage after classic open surgery (OPEN) and minimally invasive spine surgery (MISS) after injury. In a randomised prospective study, we evaluated our hypothesis that MISS would result in a lower extent of atrophy and fibrosis as detected by MRI. MRI was performed after the injury and not earlier than 3 months after the removal of implants. 16 OPEN and 16 MISS patients underwent the final follow-up. Both atrophy and muscle fibrosis were assessed based on the progression of the condition after the surgery from the pre-operative state. Atrophy was assessed using T2-weighted axial...

A thorough understanding of pedicle morphometrics is crucial for selecting suitable pedicle screws and their optimal trajectory in spinal stabilization. This study aims to provide a detailed morphometric analysis of lumbar pedicles in a Turkish population from the Aegean region, considering gender and age based on CT scans. This retrospective study analyzed CT scans of 500 lumbar vertebrae from 100 healthy individuals (50 females, 50 males) residing in the Aegean region of Turkey. Our study found that pedicule axial length (PAL), pedicle width (PW), pedicle height (PH), and foramen vertebra transverse diameter (FTD) parameters were significantly...

Usability of Ultrasonography in the Diagnosis of Pediatric Fractures

Acta Chir Orthop Traumatol Cech. 2026; 93(1):40-46 | DOI: 10.55095/achot2026/002  

The study aims to evaluate the usability of ultrasonography in the diagnosis of pediatric fractures. Ultrasound examination of patients with fractures diagnosed using radiography at the Clinic of Pediatric and Trauma Surgery, Third Faculty of Medicine, Charles University and UTH between 27 May 2024 and 31 December 2024. We identified a total of 11 areas to be examined - clavicle, proximal humerus, elbow, forearm, metacarpal bones, fingers of the upper limb, sternum, femur, tibia, ankle, and metatarsal bones. The examination was performed independently by a surgeon and a radiologist, who selected the patients randomly during their treatment at the...

Comparison of Usability of Sagittal Plane Parameters with Baumann Angle in Radiological Imaging of Supracondylar Humerus Fractures

Acta Chir Orthop Traumatol Cech. 2026; 93(1):47-52 | DOI: 10.55095/achot2025/030  

Radiological studies in supracondylar humerus fractures (SCHF) often focus on coronal plane imaging. In our study, we focused on the measurements used in elbow sagittal plane imaging. We investigated the role of humeral shaft condylar angle (SCA) and lateral capitellohumeral angle (LCHA) in determining the reduction quality by comparing them with Baumann angle (BA). İnvestigated its effectiveness in assessing the reduction of the teardrop figure and in the follow-up period. Eighty-eight patients with SCHF were included in the study. BA, SCA and LCHA measurements were taken on the non-fractured contralateral elbow. The same measurements were made...

There Is No Clinical and Radiological Difference between Suspensory and Cortical Button Fixation at the Treatment of Medial Meniscus Posterior Root Tear

GÜNEŞ SARIKAYA, AHMET EMRE PAKSOY, ÖMER KARAŞAHİN, MEHMET KÖSE, MATTHİE P OLLİVİER, BARIŞ KOCAOĞLU

Acta Chir Orthop Traumatol Cech. 2026; 93(1):53-58 | DOI: 10.55095/achot2026/001  

The purpose of this prospective study was to compare the two surgical techniques; (Transosseous Fixation with the Suspensory Fixation System technique and Pull Out Suture Repair) for clinical and radiologic scores and to investigate the effects on meniscal extrusion in Medial Meniscus Posterior Root Tear (MMPRT). This was a prospective single-center study. Patients undergoing MMPRT were divided into two groups. Group 1 patients were repaired with Transosseous Fixation with The Suspensory Fixation System technique while Group 2 patients were repaired with Pull Out Suture Repair with Cortical Button. Lysholm and Tegner Score, Visual Analog Scale (VAS),...
