Background: Resorption of hard and soft tissues following immediate implant insertion is frequently reported. Data regarding the influencing factors on facial tissue thickness are rare.
Purpose: This retrospective study investigated the impact of connective tissue grafting, the orofacial angulation and position of immediately inserted and provisionalized implants on the facial hard and soft tissue thickness in the anterior maxilla within a 1- to 5-year follow-up.
Material And Methods: Implants with the prerequisite of having preoperative and postoperative cone beam computed tomography (CBCT) and a follow-up of 1 to 5 years were included. Facial bone deficiencies were grafted flaplessly with autogenous bone in all sites. In a subgroup of implants additional connective tissue grafting was performed, whereas the remaining implants were not grafted with soft tissue. The orofacial tooth and implant angulation, the change of horizontal position and the facial bone thickness were measured by CBCT, the facial mucosa thickness by an ultrasonic device.
Results: In total, 76 implants were placed in 55 patients. Sixty-nine sites showed a facial bone defect. Thirty-eight received a connective tissue graft additionally. All implants were still in function after a mean follow-up of 36 months. The mean thickness of the facial mucosa was 1.72 mm at 1 mm, 1.63 mm at 4 mm, 1.52 mm at 6 mm, and 1.66 mm at 9 mm apically to mucosal margin. The bone thickness was 0.02, 0.25, and 0.36 mm initially and 1.32, 1.26, and 1.11 mm finally at 1, 3, and 6 mm apically to implant shoulder level. Mixed model analysis revealed an impact of the preoperative bone status on the facial bone increase. The facial soft tissue thickness was significantly influenced by the gingival biotype.
Conclusions: The results indicate that an initial severe hard tissue defect allows for significant bone regeneration. The facial soft tissue thickness is primarily influenced by the gingival biotype.

Introduction: Solitary plasmacytomas are tumors characterized by a local increase of malignant plasma cells in soft tissue or bone and may occur anywhere without evidence of systemic disease. The aim was to focus on the main surgical techniques and outcomes for this rare chest wall tumor.
Methods: Patients with solitary plasmacytoma involving a rib, who were operated for diagnostic or treatment purposes between 2018 and 2023 were retrospectively reviewed.
Lisfranc Fracture-dislocation With Extensor Hallucis Brevis Tendon Interposition: A Case Report.

Case: A 14-year-old adolescent girl sustained a Lisfranc fracture-dislocation with an interposed extensor hallucis brevis (EHB) tendon. Following multiple failed attempts at closed reduction in both the emergency department and the operating room, the patient was treated in a staged manner with temporizing closed reduction and percutaneous pinning in improved alignment, followed by definitive open reduction and internal fixation once soft tissues allowed.
Conclusions: Anatomic reduction and stable fixation of Lisfranc injuries is vital to regain stability and reduce the risk of midfoot arthritis and collapse.
Successful Healing After Minimally Invasive Subtalar Fusion Following Comminuted Open Calcaneus Fracture: A Case Report.
JBJS Case Connect

Department of Orthopaedics, Mass General Brigham, Boston, Massachusetts.
Case: A 51-year-old male polytrauma patient presented with bilateral calcaneus fractures after a fall. This report describes treatment of his right comminuted Sanders IV calcaneus fracture with percutaneous open reduction internal fixation (ORIF) and minimally invasive surgery (MIS) primary subtalar fusion to restore alignment and preserve soft tissue.
Conclusion: Unlike traditional open approaches, which are prone to wound complications due to larger incisions, our approach of maintaining fracture alignment during joint preparation using an MIS burr for acute posttrauma subtalar arthrodesis and percutaneous ORIF appears to have reduced these risks, resulting in successful radiological healing and functional recovery at 1-year follow-up.
Synthesis and preclinical evaluation of tigilanol tiglate analogs as latency-reversing agents for the eradication of HIV.

Tigilanol tiglate (EBC-46) is a selective modulator of protein kinase C (PKC) isoforms that is Food and Drug Administration (FDA) approved for the treatment of mast cell tumors in canines with up to an 88% cure rate. Recently, it has been FDA approved for the treatment of soft tissue sarcomas in humans. The role of EBC-46 and, especially, its analogs in efforts to eradicate HIV, treat neurological and cardiovascular disorders, or enhance antigen density in antigen-targeted chimeric antigen receptor-T cell and chimeric antigen receptor-natural killer cell immunotherapies has not been reported.

Chemical modification of naturally derived glycosaminoglycans (GAGs) expands their potential utility for applications in soft tissue repair and regenerative medicine. Here we report the preparation of a novel crosslinked chondroitin sulfate (~200 to 2000 kilodaltons) that is both soluble in aqueous solution and microfilterable. We refer to these materials as "SuperGAGs.
