Improved clinical outcome after medial open-wedge osteotomy despite cartilage lesions in the lateral compartment.

High tibial medial open-wedge osteotomy (HTO) is an established treatment option for cartilage lesions in the medial compartment. It was this study's aim to evaluate the effect of asymptomatic single or kissing lesions in the lateral compartment on functional outcome after medial open-wedge osteotomy. A total of 156 patients were enrolled in this retrospective study. All patients underwent HTO due to a varus deformity and a symptomatic cartilage lesion or osteoarthritis in the medial compartment. We acquire...


Imaging of the post-operative medial elbow in the overhead thrower: common and abnormal findings after ulnar collateral ligament reconstruction and ulnar nerve transposition.

Ulnar collateral ligament (UCL) reconstruction is now being performed more commonly and on younger patients than in prior decades. As a result, radiologists will increasingly be asked to evaluate elbow imaging of patients presenting with pain who have had UCL reconstruction. It is essential for radiologists to understand the normal and abnormal imaging appearances after UCL reconstruction and ulnar nerve transposition, which is also commonly performed in overhead-throwing athletes. Doing so will allow radio...

MRI comparison of injury mechanism and anatomical factors between sexes in non-contact anterior cruciate ligament injuries.

Non-contact anterior cruciate ligament (ACL) rupture is mostly caused by a pivot shift mechanism including valgus collapse and internal tibial rotation. In female athletes, the incidence of ACL rupture has been reported to be significantly higher than in their male counterparts. However, to date, there have been limited reports and controversy regarding sex differences underlying injury mechanisms of ACL and severity of injury. In this study, we hypothesized that 1) in patients with non-contact ACL rupture,...


The neglected medial part of macaque area PE: segregated processing of reach depth and direction.

Area PE (Brodmann's area 5), located in the posterior parietal cortex (PPC), is involved in the control of arm movements. Many monkey studies showed PE's involvement in reach directions, while only a few revealed signals coding the depth of reaches. Notably, all these studies focused on the lateral part of PE, leaving its medial part functionally largely unexplored. We here recorded neuronal activity in the medial part of PE in three male Macaca fascicularis while they performed coordinated eye and arm move...

Overexpression of Pitx1 attenuates the senescence of chondrocytes from osteoarthritis degeneration cartilage-A self-controlled model for studying the etiology and treatment of osteoarthritis.

To explore the role of low expression of Pitx1 in degenerative cartilage tissue. A cartilage injury model was established by using the cartilage scratch method. The newly generated tissue by BrdU labeled in injured cartilage region expressed SOX-9 and Col2A1 in 5-week-old rats. Compared with that, the number of BrdU-positive cells was lower in 4-month-old cartilage injury model rats. Compared with that in lateral cartilage, the expression of Pitx1 was lower in medial cartilage. Compared with chondrocytes de...

Anterior Trunk Muscle Shows Mix of Axial and Appendicular Developmental Patterns.

Skeletal muscle in the trunk derives from the somites, paired segments of paraxial mesoderm. Whereas axial musculature develops within the somite, appendicular muscle develops following migration of muscle precursors into lateral plate mesoderm. The development of muscles bridging axial and appendicular systems appears mixed.

Acute Unilateral Ptosis and Myositis Following the H1N1 Influenza Vaccine.

The authors present a rare case of sudden onset unilateral complete ptosis occurring hours after administration of the H1N1 influenza vaccine. A complete workup for autoimmune and neurological disease was negative. MRI of the orbits demonstrated unilateral orbital myositis involving the left superior rectus/levator complex, superior oblique, and medial rectus muscles. Ptosis resolved spontaneously over 2 months without intervention. An autoimmune mechanism may explain rare cases of orbital myositis followin...

Rectus sheath single-injection blocks: a study to quantify local anaesthetic absorption using serial ultrasound measurements and lidocaine serum concentrations.

Rectus sheath blocks are an established option for analgesia following abdominal surgery, but pharmacokinetic data are limited. This study sought to characterise the absorption of lidocaine injectate and the pharmacokinetics of lidocaine after rectus sheath injection.

Biomechanical behavior of three types of fixation in the two-part proximal humerus fracture without medial cortical support.

The purpose of this study was to evaluate the role of a non-locking plate applied to the anteromedial surface of the proximal humerus on loads at the implant-bone interface of non-locking and locking lateral plate fixation of proximal humeral fractures with a medial gap.

The Effect of Cartilage Lesion in the Lateral Compartment of the Knee on the Surgical Outcome of Medial Open-Wedge High Tibial Osteotomy.

The aim of this study was to identify the effect of cartilage lesion in the lateral compartment of the knee on the surgical outcome of medial open-wedge high tibial osteotomy (MOWHTO). A total of 172 consecutive patients who underwent MOWHTO were evaluated retrospectively. Among the patients who underwent second-look arthroscopic assessment, 30 patients with lateral compartment cartilage lesion (group 1: ≥ grade 2 cartilage lesion according to the International Cartilage Repair Society [ICRS] grading ...

Renal Medullary Carcinoma With Metastasis to the Temporal Fossa and Orbit.

A 22-year-old Hispanic man with sickle cell trait presented with blurred vision, double vision, and pain with OD movement. MRI demonstrated an extra-axial mass centered around the temporal bone with extension into the middle cranial fossa and lateral aspect of the extra-conal right orbit, and mass effect on the lateral rectus muscle. Biopsy of the lesion was consistent with renal medullary carcinoma. CT chest/abdomen/pelvis confirmed a primary tumor in the right kidney. No additional metastases were found. ...

Neuromuscular junctions are stable in patients with cancer cachexia.

Cancer cachexia is a major cause of patient morbidity and mortality, with no efficacious treatment or management strategy. Despite sharing pathophysiological features with a number of neuromuscular wasting conditions, including age-related sarcopenia, the mechanisms underlying cachexia remain poorly understood. Studies of related conditions suggest that pathological targeting of the neuromuscular junction (NMJ) may play a key role in cachexia, but this has yet to be investigated in human patients. Here, hig...

Traumatic Hallux Varus in Association with Agenesis of the Fibular Sesamoid: A Case Study.

Hallux varus is most commonly seen iatrogenically following overaggressive lateral release, removal of the fibular sesamoid, or overaggressive removal of the medial eminence. There are several reported cases of traumatic hallux varus, although this is much less common. We present a case of traumatic hallux varus in a patient who was later found to have bilateral absence of her fibular sesamoids. We postulated that lack of her fibular sesamoid led to weakness of her lateral capsular ligaments, thereby making...

Introducing the Lateral Femoral Condyle Index as a Risk Factor for Anterior Cruciate Ligament Injury.

The asymmetry of the medial and lateral knee compartments contributes significantly to femorotibial biomechanics and pivoting, and it is reported to be a relevant risk factor for an anterior cruciate ligament (ACL) injury.

Emerging Temporal Lobe Dysfunction in People at Clinical High Risk for Psychosis.

Clinical high-risk (CHR) individuals have been increasingly utilized to investigate the prodromal phases of psychosis and progression to illness. Research has identified medial and lateral temporal lobe abnormalities in CHR individuals. Dysfunction in the medial temporal lobe, particularly the hippocampus, is linked to dysregulation of glutamate and dopamine a hippocampal-striatal-midbrain network that may lead to aberrant signaling of salience underpinning the . Similarly, lateral temporal dysfunction may...

Transcavernous sinus pituitary gland transposition: how I do it.

Pituitary transposition preserving gland function is possible when approaching superior clival region tumors. Clinical experience along with detailed anatomical knowledge makes this technique safe and effective.

The crystal structure of the naturally split gp41-1 intein guides the engineering of orthogonal split inteins from cis-splicing inteins.

Protein trans-splicing catalyzed by split inteins has increasingly become useful as a protein engineering tool. We solved the 1.0 Å-resolution crystal structure of a fused variant from the naturally split gp41-1 intein, previously identified from environmental metagenomic sequence data. The structure of the 125-residue gp41-1 intein revealed a compact pseudo-C2-symmetry commonly found in the Hedgehog/Intein (HINT) superfamily with extensive charge-charge interactions between the split N- and C-terminal int...

Adjusting gait step-by-step: Brain activation during split-belt treadmill walking.

When walking on a split-belt treadmill, where each leg is driven at a different speed, a temporary change is made to the typical steady-state walking pattern. The exact ways in which the brain controls these temporary changes to walking are still unknown. Ten young adults (23±3y) walked on a split-belt treadmill for 30 min on 2 separate occasions: tied-belt control with both belts at comfortable walking speed, and continuous adjustment where speed ratio between belts changed every 15 s F-fluorodeoxyglu...

Transforming growth factor beta 1 signaling is altered in the spinal cord and muscle of amyotrophic lateral sclerosis mice and patients.

Gender differences characterize amyotrophic lateral sclerosis (ALS). Because ALS patients have increased circulating levels of transforming growth factor beta 1 (TGFB1), here we analyzed gender and disease progression-related modification of TGFB1 and its related signaling molecules in the spinal cord and skeletal muscle of ALS mice and in muscle biopsies from sporadic ALS patients. At presymptomatic stage, Tgfb1 mRNA expression is reduced in the mouse spinal cord but is increased selectively in the male sk...

Does hamstrings co-contraction constrain knee internal rotation in patients with knee endoprosthesis during decline slope walking?

Medial and lateral hamstrings are known for their capacity to promote internal or external rotation of the knee. Apart from implant geometry, increased co-contraction to a larger share of either the medial or lateral hamstrings has the potential to contribute to the restricted knee internal rotation especially under consideration of cruciate ligament substituting compared to cruciate ligament retaining knee endoprosthesis designs. Hence, the purpose of the study was to evaluate, whether increased co-contrac...

Echo Intensity Reliability for the Analysis of Different Muscle Areas in Athletes.

Lanferdini, FJ, Manganelli, BF, Lopez, P, Klein, KD, Cadore, EL, and Vaz, MA. Echo intensity reliability for the analysis of different muscle areas in athletes. J Strength Cond Res 33(12): 3353-3360, 2019-Skeletal muscles' echo intensity (EI) is used as a parameter to evaluate muscle damage and muscle quality after exercise or training. However, recent muscle EI studies have used regions of interest (ROIs) of different sizes for assessing muscle damage and muscle quality, which may lead to different results...

Long-Term Serial Measurement of Muscle Volume in TRAM Flaps Using the Eclipse Treatment Planning System.

Muscle flaps used in reconstructive surgery are known to lose volume over time because of denervation and disuse atrophy. However, there is currently no agreement on a quantitative approach to evaluating volume changes. Here, long-term serial measurement of muscle volume in transverse rectus abdominis musculocutaneous (TRAM) flap breast reconstruction has been conducted using the Eclipse treatment planning system.

Thalamo-cortical coupling during encoding and consolidation is linked to durable memory formation.

Memory formation transforms experiences into durable engrams. The stabilization critically depends on processes during and after learning, and involves hippocampal-medial prefrontal interactions that appear to be mediated by the nucleus reuniens of the thalamus in rodents, which corresponds to the human medioventral thalamus. How this region contributes to durable memory formation in humans is, however, unclear. Furthermore, the anterior-, lateral dorsal-, and mediodorsal nuclei appear to promote mnemonic f...

No effect of triple-pulse TMS medial to intraparietal sulcus on online correction for target perturbations during goal-directed hand and foot reaches.

Posterior parietal cortex (PPC) is central to sensorimotor processing for goal-directed hand and foot movements. Yet, the specific role of PPC subregions in these functions is not clear. Previous human neuroimaging and transcranial magnetic stimulation (TMS) work has suggested that PPC lateral to the intraparietal sulcus (IPS) is involved in directing the arm, shaping the hand, and correcting both finger-shaping and hand trajectory during movement. The lateral localization of these functions agrees with the...
