Anatomical-Based Diagnosis and Filler Injection Techniques: Perioral Wrinkles.

This study focuses on anatomically based diagnosis and filler injection techniques for managing perioral wrinkles, which present unique challenges due to complex vascular anatomy and diverse wrinkle types. Key perioral wrinkles include vertical lip wrinkles (smoker's lines), oblique lip-chin creases, labiomental creases, central chin creases, and marionette lines. Effective treatment requires understanding the underlying anatomy and careful procedural planning.

Anatomical Guideline for Retrobulbar Hyaluronidase Injection.

Background: Vision loss following cosmetic filler injections is a rare but devastating complication resulting from inadvertent intravascular embolization, most often affecting the ophthalmic artery. Retrobulbar hyaluronidase injection has been proposed as an emergency intervention, yet anatomical guidelines for its administration remain poorly defined.

Objective: To propose an anatomically informed protocol for safe and effective retrobulbar hyaluronidase injection in cases of filler-induced central retinal artery occlusion.

Intermediate-Term Clinical Outcomes After the Shortening Arthrodesis for Ankle Arthropathy with Severe Bone Defect.

The most common limb-salvage procedure for end-stage ankle arthropathy with severe bone defect is arthrodesis. Successful fusion requires rigid metal fixation, effective filling of the bone defect space, and maximal securing of the contact area between the tibia and talus. In cases with severe bone defect, sufficient grafting using autogenous bone alone is limited, and there is still controversy regarding the effectiveness of allogeneic or xenogeneic bone grafting.

This article presents the intermediate-term clinical and radiologic outcomes following AOT for lateral OLTs.

Usefulness of Suture-Tape Augmentation Based on Intraoperative Ankle Stress Radiographs During Anatomical Ligament Repair for Chronic Lateral Ankle Instability.

Background: During the modified Broström procedure for chronic ankle instability, surgeons often experience cases with insufficiently restored mechanical stability even after anatomical ligament repair. In these cases, longer postoperative immobilization and delayed rehabilitation can be required, and a risk for recurrence of instability may persist. This study aimed to evaluate the clinical usefulness of suture-tape augmentation based on intraoperative stress radiographs during anatomical ligament repair for chronic ankle instability.

Isolated Subtalar Repositional Arthrodesis Compared With Triple Arthrodesis for the Treatment of Progressive Collapsing Foot Deformity.

The optimal extent of arthrodesis for severe and rigid progressive collapsing foot deformity is controversial. Traditionally, triple arthrodesis has been recommended; however, good results have been reported using subtalar arthrodesis only. We compared the results of triple arthrodesis and isolated subtalar repositional arthrodesis.

Point-of-Care Testing of the MTF1 Osteoarthritis Biomarker Using Phenolphthalein-Soaked Swabs.

Osteoarthritis (OA) is the most common joint disease, which accompanies pain and inconvenience in daily life owing to degradation of cartilage and adjacent tissues. In this study, we propose a simple point-of-care testing (POCT) kit for the detection of the MTF1 OA biomarker to achieve on-site clinical diagnosis of OA. The kit contains an FTA card for patient sample treatments, a sample tube for loop-mediated isothermal amplification (LAMP), and a phenolphthalein-soaked swab for naked eye detection.

Comparison of Intermediate-Term Clinical Outcomes Between Medial and Lateral Osteochondral Lesions of the Talus Treated With Autologous Osteochondral Transplantation.

Background: The conventional operative method to treat an osteochondral lesion of the talus (OLT) is through bone marrow stimulation (BMS). Autologous osteochondral transplantation (AOT) is being used as an alternative option in cases with a large OLT, accompanying subchondral cyst, and/or failed BMS. We aimed to compare the intermediate-term clinical and radiologic results between medial and lateral OLTs after an AOT procedure.

Anatomic anterior talofibular ligament repair augmented with suture-tape for chronic ankle instability with poor quality of remnant ligamentous tissue.

Purpose: Because modified Broström procedure provides a restoration of mechanical stability by reinforcing attenuated host tissue, poor quality of remnant ligamentous tissue is considered as a prognostic factor for ligament repair surgery. The purpose of this study was to assess the intermediate-term clinical results after anatomic anterior talofibular ligament repair augmented with suture-tape for chronic lateral ankle instability (CLAI) with poor quality of ligament remnants.

Methods: 64 patients with the insufficient anterior talofibular ligament confirmed by preoperative magnetic resonance image and intraoperative inspection were followed for ≥3 years after the augmented anterior talofibular ligament repair.

The Effects of Tibialis Anterior Tenotomy on Wound Complications and Functional Outcomes After Anterior Fusion Plating for Severe Ankle Arthritis.

Nonunion is known to be a relatively common complication following ankle arthrodesis. Various fixation techniques have been introduced to enhance the stability and to improve fusion rate. With the use of anterior plate supplementation, postoperative wound problems have been frequently reported despite better fusion rate.

The Influence of Suture-Tape Augmentation on Biological Healing of the Anterior Talofibular Ligament in Chronic Ankle Instability: A Quantitative Analysis Using MRI.

While the effectiveness of suture-tape augmentation for chronic ankle instability has been supported biomechanically and clinically, little information is available regarding biological changes of the lateral ligaments postoperatively. This study aims to quantitatively evaluate ligament regeneration with MRI after suture-tape augmentation. Forty-six patients underwent MRI scan at follow-up of a minimum of 1 year after lateral ligaments augmentation using suture-tape.

A quantitative evaluation of the individual components contributing to the functional ankle instability in patients with modified Broström procedure.

Residual functional ankle instability regardless of the restoration of mechanical stability after the lateral ligament repair or reconstruction can cause recurrent sprain. The purpose of this study was to identify the sequential changes of joint-position sense, peroneal strength, postural control, and functional performance ability after the modified Broström procedure (MBP) for chronic ankle instability. A total of 46 patients (46 ankles) underwent the MBP for chronic ankle instability were eligible for this study and were followed for 1 year postoperatively.
