Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Effect of volume for injection of the 15th to 16th thoracic interspinous space: An ex vivo study

Equine Veterinary Journal, EarlyView.
Abstract Background Impinging (overriding) spinous processes (ISPs) are commonly identified in horses with back pain. Diagnostic analgesia is widely used as the clinical reference standard for confirming association with clinical signs of back pain, but the specificity of dorsal spinous region diagnostic analgesia remains poorly understood.

Reverse coronal deformity does not adversely affect clinical outcomes or early survivorship following image‐based robotic total knee arthroplasty performed under functional alignment

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Reverse coronal deformity (RCD) is characterized by a ≥2° reversal of coronal alignment between knee extension and 90° of flexion. This study evaluated clinical outcomes, intraoperative alignment characteristics, and early revision rates in patients with RCD undergoing image‐based robotic‐assisted total knee arthroplasty (TKA) using ...

Posterolateral corner reconstruction using hamstrings grafts—A comparative biomechanical study of three techniques

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare three posterolateral corner (PLC) reconstruction techniques—the popliteofibular loop (PFLoop), the modified LaPrade (LP) and modified Arciero (AR) techniques—in restoring knee laxity in varus (VR), external tibial rotation (ER) and posterior tibial translation (PTT). Methods Nine cadaveric knees were subjected to 8Nm VR, 5Nm

Progressive lateral femoral condyle lengthening in total knee arthroplasty produces dose‐dependent increases in patellofemoral joint loading and alters patellar tracking

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To examine the biomechanical effects of progressive lateral femoral condyle lengthening on patellofemoral joint (PFJ) kinematics and kinetics following total knee arthroplasty (TKA), and to determine whether lateral condyle distalisation produces measurable, dose‐dependent alterations in PFJ loading and patellar tracking. Methods Eight

Celiac artery compression: Dunbar syndrome

Jornal Vascular Brasileiro
Celiac artery compression syndrome, also referred to as median arcuate ligament syndrome, celiac axis syndrome or Dunbar syndrome is a rare disorder consequent to extrinsic compression of the celiac trunk by the median arcuate ligament.

Current concepts in isolated and combined injuries of the medial collateral ligament complex—Part I: Anatomy, biomechanics, clinical and radiological examination of the medial collateral ligament of the knee

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Injuries involving the medial collateral ligament (MCL), or combined injuries to both the anterior cruciate ligament (ACL) and MCL, are common and present considerable diagnostic and therapeutic challenges. Better understanding of MCL anatomy and biomechanics, especially in combined ACL–MCL injuries, has driven the need for updated clinical ...

Safe laparoscopic surgery in median arcuate ligament syndrome

Videosurgery and Other Miniinvasive Techniques, 2018
The median arcuate ligament syndrome is a rare clinical condition with no standardized method of laparoscopic treatment. Exposure of the aorto-celiac axis might be considered as the most challenging part of the surgical procedure.

Rapid Postmortem Temporal Bone Extraction and Dissection of Human Inner Ear Organs From Organ Donors

The Laryngoscope, EarlyView.
We developed a postmortem protocol for temporal bone extraction and dissection in organ donors, enabling atraumatic bilateral temporal bone retrieval within 1–2 h of ischemia, followed by stepwise microsurgical dissection of neurosensory organs. Combining rapid extraction, abbreviated decalcification, and atraumatic microsurgical dissection, this ...

Oppositely Charged Homopolypeptides Form Ordered Helix Assemblies With Hierarchical Structure

Small, EarlyView.
Hexagaonal and square assembly of polyarginine alfa‐helices formed in highly ordered polyarginine/polyaspartic acid complexes. The helices exhibit additional periodic staggering along their helical axis. ABSTRACT Oppositely charged polyelectrolytes are known to form polyelectrolyte complexes.
