Article Synopsis
  • The study compares the mechanical strength of short-length uni-cortical screws (SL75UCS) and full-length screws (FL100S) in a distal radius fracture model using cadaver wrists.
  • No significant differences were found in stiffness, elastic limit, or maximal force between the two screw types under axial and torsional compression tests.
  • The results suggest that SL75UCS can be a safe alternative to FL100S in treating distal radius fractures, potentially lowering the risk of complications like extensor tendon injuries.

Background: Midfoot osteotomy is often used in the surgical treatment of foot deformities. The percutaneous Gigli saw osteotomy (PGSO) technique has many advantages compared with known osteotomy techniques. We aimed to show the efficacy and reliability of the PGSO technique in the midfoot of fresh frozen cadavers without using an image intensifier.

Background And Objectives: Literature does not show any studies regarding plate placement problems in the coronal plane of patients with volar plating due to distal radius fracture diagnosis. We aimed to investigate the functional and laboratory results of the coronal malposition of the volar locking plate in patients with distal radius fracture treated with internal fixation.

Methods: In this retrospective study, we included patients who had volar plate fixation, were aged between 18 and 80, had no pathological fracture, had a minimum of six months of follow-up, and had the same rehabilitation protocol.

Background: The objective of this study was to evaluate the risk of femur intertrochanteric fracture associated with femur trochanter major fractures in patients over 65 years of age with magnetic resonance examination for better diagnosis and treatment.

Methods: Thirty-one patients who had incomplete femur intertrochanteric fracture diagnosed were included in the study. Patients were classified according to the length of the fracture line crossing the intertrochanteric border.

Although Langerhans cell histiocytosis (LCH) may arise from any bone, flat bones (skull, ribs, scapula, clavicle, and mandible) are more commonly involved.The overall reported incidence of scapular involvement by LCH is nearly 3% in the literature. Intra-lesional corticosteroid injection can be given for lesions that cause pain or postural deformity.

Aim: To evaluate the changes in the pressure values of the ulnar nerve after in-situ decompression and anterior subcutaneous transposition of the ulnar nerve.

Material And Methods: The ulnar nerve was released in the postcondylar groove. An ultrathin (100 lm) force transducer was embedded between the posterior of the ulnar nerve and the anterior of the medial epicondyle.

Objective: The aim of this study was to investigate the efficacy and safety of Computed Tomography (CT) guided percutaneous Radiofrequency Ablation (RFA) in the treatment of osteoid osteoma (OO).

Methods: A total of 116 patients (82 male and 34 female patients; mean age of 17.7 years; age range 13-months-42 years) who had 118 CT guided RFA treatment between June 2015 and November 2018 (42 moths) with the diagnosis of OO were included in this study.

Background: Osteoid osteoma (OO) is one of the most commonly occurring benign bone tumors. It constitutes 10-12% of benign bone tumors and 2-3% of primary bone tumors. In radiofrequency ablation (RFA) treatment, the cells of the tumor are thermally inactivated by the help of electrodes shaped like needles.

We present a 13-month-old boy who had a successful Computed Tomography (CT) guided percutaneous radiofrequency ablation (RFA) treatment for the osteoid osteoma (OO) on proximal part of the tibial diaphysis. The complaints of the patient were being restless due to pain and refusing to bear any weight on his left leg for 6 months. An asymmetrical cortical thickening and a focal sclerosis was detected on medial proximal diaphysis of the left tibia on radiographs and axial T2-weighted STIR-MR image showed bone marrow and soft-tissue edema with low-signal-intensity nidus due to central calcification with a high-signal-intensified unmineralized periphery.

Introduction: To present the effect of the cerclage fixation, which was performed for the purpose of preserving the alignment obtained by open reduction, on the long-term clinical and radiological results of subtrochanteric fractures.

Materials And Methods: The inclusion criterias were at least 2 years of follow-up, no severe cognitive impairment, and to be able to walk independently prior to fracture. Patients with transverse or short oblique subtrochanteric hip fractures (AO/OTA class 32-A3.

Background: Complications related to extensor tendons have begun to increase with the use of volar plates in the treatment of distal radius fractures. In this study, we aimed to compare four-plane radiography and ultrasonography in the evaluation of dorsal cortex screw penetration following volar plate fixation.

Methods: We recruited 47 patients (33 males, 14 females, mean age 37.

Primary malignant vascular tumors which constitute less than 1% of the primary bone tumors are very rarely encountered. Epithelioid angiosarcoma is a very uncommon subtype of angiosarcomas presenting with an epithelioid phenotype and mimicking carcinomas clinically. These tumors select mostly extra-skeletal locations but rarely bones as their medium.

Objective: Anatomic volar rim locking plates are designed with the aim of treating intraarticular distal radius fractures. When used to treat comminuted distal radius fractures, these plates can damage the flexor tendons. In this study, we sought to determine the radiological and functional results and rate of complications of these plates.

Ligament laxity measurement is clinically valuable to diagnose the injury and also to compare the laxity before and after surgical procedure. The aim of the study was to compare the accuracy of the Lachman and Anterior Drawer Tests to evaluate the knee examination with the KT1000 arthrometer after the anterior cruciate ligament (ACL) surgery in early follow-up period. Fourty ACL reconstructed knees were examined with the Lachman and Anterior Drawer Tests, and KT1000 arthrometer with compariable intact knee of the same patients.

Introduction: Most of the ACL reconstruction is done with isometric single-bundle technique. Traditionally, surgeons were trained to use the transtibial technique (TT) for drilling the femoral tunnel. Our study compared the early postoperative period functional and clinical outcomes of patients who had ACL reconstruction with TT and patients who had ACL reconstruction with anatomical single-bundle technique (AT).

Purpose: To evaluate with ultrasound the thickness of the flexor pollicis longus (FPL) tendon and its relationship to the volar locking plate after the fixation of distal radius fractures.

Methods: We evaluated 27 type C2 and C3 distal radius fractures with ultrasound to evaluate damage to the FPL tendon after volar plate fixation. The thickness of the FPL tendon and its distance to the volar plate in the involved wrists and to the volar rim in the contralateral uninjured wrist were measured on sonograms taken 12 months postoperatively.

After anterior cruciate ligament (ACL) reconstruction, which muscle groups are more affected from frequently developing thigh muscle atrophy is a matter of debate. We evaluate the effect of thigh circumference difference between patients' knees who were administered the ACL reconstruction with hamstring tendon autograft and intact knees, on torque between the hamstring and quadriceps muscles. Fifty-five patients at least 6 months follow-up period available were included in our study.
