Is WALANT Really Necessary in Outpatient Surgery?

J Pers Med

December 2024

Department of Orthopaedics and Traumatology, Universita' Cattolica del Sacro Cuore, Largo Agostino Gemelli 8, 00168 Rome, Italy.

: The Wide Awake Local Anesthesia No Tourniquet (WALANT) technique has revolutionized outpatient hand surgery, enabling procedures such as carpal tunnel release and trigger finger release without a tourniquet. Its benefits include patient cooperation during surgery, especially for tendon repairs. However, WALANT has limitations, including a steep learning curve, longer operative preparation time, and risks such as digital ischemia and adrenaline-induced cardiac ischemia.

January 2025

Department of Polymer Nano Science & Technology and Polymer Materials Fusion Research Center, Jeonbuk National University, 567 Baekje-daero, Deokjin-gu, Jeonju-si 54896, Jeonbuk, Republic of Korea.

Articular cartilage faces challenges in self-repair due to the lack of blood vessels and limited chondrocyte concentration. Polydeoxyribonucleotide (PDRN) shows promise for promoting chondrocyte growth and cartilage regeneration, but its delivery has been limited to injections. Continuous PDRN delivery is crucial for effective cartilage regeneration.

The objective of this study was to analyze treatment approaches and outcomes according to patients' perspectives for patients with indeterminate spinal instability caused by neoplastic lesions. Data were collected from 31 patients with a total of 147 spinal neoplastic lesions, 29 of whom had lesions classified as indeterminate. These lesions were divided into two groups: the low indeterminate group (SINS 7-9) and the high indeterminate group (SINS 10-12).

Multi-ligament reconstruction in adolescent patients affected by congenital femoral deficiency is an extremely rare and delicate surgical procedure. There are very few reported cases of complete anterior and posterior cruciate ligament agenesis in these patients. We present a complex case of a 16-year-old girl affected by congenital femoral deficiency and ipsilateral tibial hypoplasia who was treated successfully for a complete agenesis of the anterior (ACL) and posterior (PCL) cruciate ligament with single-sitting ACL and PCL reconstruction.

Objectives: The aim of the present study was to examine the growth dynamics of the first sacral vertebra and its ossification center in the human fetus, based on their linear, planar, and volumetric parameters.

Methods: The examinations were carried out on 54 human fetuses of both sexes (26 males and 28 females) aged 18-30 weeks of gestation, which had been preserved in 10% neutral formalin solution. Using CT, digital image analysis software, 3D reconstruction, and statistical methods, the size of the first sacral vertebra and its ossification center was evaluated.

The anterior cruciate ligament (ACL) is one of the most injured ligaments, with approximately 100,000 ACL reconstructions taking place annually in the United States. In order to successfully manage ACL rupture, it is of the utmost importance to understand the anatomy, unique physiology, and biomechanics of the ACL, as well as the injury mechanisms and healing capacity. Currently, the "gold standard" for the treatment of ACL ruptures is surgical reconstruction, particularly for young patients or athletes expecting to return to pivoting sports.

Although osteosarcomas are the most frequent primary malignant bone tumors, the primary cranial manifestation of this condition is very rare with only a limited number of cases presented in the literature. We present the case of a 20-year-old male patient who underwent single-session surgical intervention for resection of right frontal osteosarcoma with a tailor-made craniotomy and cranioplasty using virtually designed 3D-printed templates and molds. Subsequently, the patient was treated according to the EURAMOS protocol and received adjuvant systemic chemotherapy.

Biosynthesis of Lysosomally Escaped Apoptotic Bodies Inhibits Inflammasome Synthesis in Macrophages.

Research (Wash D C)

January 2025

Department of Plastic and Reconstructive Surgery, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200011, P. R. China.

Hyperglycemia and bacterial colonization in diabetic wounds aberrantly activate Nod-like receptor protein 3 (NLRP3) in macrophages, resulting in extensive inflammatory infiltration and impaired wound healing. Targeted suppression of the NLRP3 inflammasome shows promise in reducing macrophage inflammatory disruptions. However, challenges such as drug off-target effects and degradation via lysosomal capture remain during treatment.

Platelet rich plasma (PRP) is an autologous blood product rich in platelets, showing promise in reducing inflammation and accelerating healing. While extensively utilized in plastic surgery, dermatology, and osteoarthritis treatment, its application in anterior cruciate ligament (ACL) injuries is limited. This article examines PRP's potential in ACL reconstruction (ACLR), exploring its history, current usage, controversies and future directions.

Department of Orthopaedics, Shanghai Key Laboratory for Prevention and Treatment of Bone and Joint Diseases, Shanghai Institute of Traumatology and Orthopaedics, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, 197 Ruijin 2nd Road, Shanghai, 200025, PR China.

Bioelectrical stimulation is a powerful technique used to promote tissue regeneration, but it can be hindered by an "electrical overload" phenomenon in the core region of stimulation. We develop a threaded microneedle electrode system that protects against "electrical overload" by delivering medicinal hydrogel microspheres into the core regions. The threaded needle body is coated with polydopamine and chitosan to enhance the adhesion of microspheres, which are loaded into the threaded grooves, allowing for their stereoscopic release in the core regions.

Objective: Heterozygous COL2A1 gene mutations are associated with type 2 collagenopathies, characterized by a wide, diverse, and overlapping clinical spectrum in related diseases. Our goal is to describe the clinical, radiological, and molecular findings of patients with COL2A1-related dysplasia and investigate the phenotype-genotype correlation. We also aim to emphasize the challenge of categorizing COL2A1-related diseases with similar clinical and radiological phenotypes.

Background: Avascular necrosis (AVN) of the femoral head is a degenerative condition characterized by ischemic bone death, resulting in pain and impaired mobility. Core decompression, a surgical intervention, is widely performed for stage II AVN to alleviate symptoms and delay disease progression. While clinical and radiological outcomes are well-documented, the psychosocial dimensions of recovery remain underexplored.

Background: Effective management of postsurgical pain following arthroplasty remains a challenge, lacking a definitive gold standard. As most knee and hip arthroplasties are cemented or hybrid, we used the property of bone cement as a drug carrier and added powdered local anesthetics (lidocaine hydrochloride and bupivacaine hydrochloride) to the polymethylmethacrylate (PMMA) as analgesics. However, the addition of drugs to bone cement may compromise its mechanical properties, necessitating a thorough analysis.

Introduction: Knee joint stability is influenced by force distribution and ligament structures. High Tibial Osteotomy (HTO) treats knee deformities and redistributes load, reducing further invasive procedures. High Tibial Osteotomy (HTO) is a well-established procedure for addressing knee instability, particularly in cases involving ligament deficiencies such as ACL and PCL insufficiencies.
