Employing Polymer and Gel to Fabricate Scaffold-like Cancellous Orthopedic Screw: Polycaprolactone/Chitosan/Hydroxyapatite.
Gels
January 2025
Department of Mechanical Engineering, Najafabad Branch, Islamic Azad University, Najafabad 8543131, Iran.
Using metallic/polymeric orthopedic screws causes cavities in bone trauma after the attachment of broken bones, which prolongs the healing. Yet, it remains unknown how to overcome such a challenge. The main aim of this research was to use both polymers and gels to fabricate and study a new PCL/chitosan/hydroxyapatite scaffold-like orthopedic screw for cancellous bone trauma.

Emergency Department, Sichuan Orthopaedic Hospital, Chengdu 610041, Sichuan, China.
Objective: To investigate the clinical efficacy of percutaneous prying combined with modified rotary reduction with needle in the treatment of supracondylar fracture of humerus in Gartland type Ⅳ children, and to evaluate the postoperative elbow joint function, the incidence of elbow varus deformity and the application prospect of this technique.
Methods: A total of 98 children diagnosed with Gartland type Ⅳ supracondylar humeral fractures between June 2020 and January 2023 were included in this study, comprising of 57 males and 41 females. The age ranged from 2 to 14 years old with an average of (6.
Clinical characteristics and removal of broken burs retained in the lower jaw.
BMC Oral Health
January 2025
State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University, Wuhan, China.
Background: A broken bur retained in the lower jaw is an uncommon complication that occurs during the extraction of the impacted mandibular third molar. The purpose of this retrospective study was to investigate the clinical characteristics of the broken burs and review our experience with the removal of the broken burs in these cases.
Methods: All patients, who suffered the broken bur remained in the lower jaw due to the extraction of the impacted mandibular third molar and presented to our hospital from July 2019 to July 2024, were included in this retrospective study.
[Comparative study of Achillon Achilles tendon suture guide combined with circuit suture via perineural channel and Krachow suture via posterolateral incision of Achilles tendon in treatment of Kuwada type Ⅱ acute closed Achilles tendon rupture].

Department of Orthopedics, the Affiliated Hospital of Xuzhou Medical University, Xuzhou Jiangsu, 221000, P. R. China.
Objective: To compare the effectiveness of Achillon Achilles tendon suture guide combined with circuit suture under the perineural channel and Krachow suture with posterolateral incision of Achilles tendon in the treatment of Kuwada type Ⅱ acute closed Achilles tendon rupture.
Methods: The clinical data of 38 patients with Kuwada type Ⅱ acute closed Achilles tendon rupture who met the selection criteria between January 2020 and December 2023 were retrospectively analyzed. Krachow suture via posterolateral incision was used in 24 cases (traditional group), and Achillon Achilles tendon suture guide combined with circuit suture via perineural channel was used in 14 cases (minimally invasive group).
Thermal Changes During Clavicle Fracture Healing in Children.
J Clin Med

Department of Surgery, University Hospital Centre Zagreb, Kišpatićeva 12, 10000 Zagreb, Croatia.
Clavicle fractures are among the most common in children, typically treated conservatively, with standard radiographs used to diagnose and monitor healing. Recently, infrared thermography (IRT) has been proposed as an alternative method for fracture detection, but no study has correlated the temperature changes during callus formation. Children aged 4-18 with X-ray-diagnosed clavicle fractures were included in the study.
