Three-dimensional planning and use of patient-specific guides improve glenoid component position: an in vitro study.
J Shoulder Elbow Surg
PUBLISHED: 08-30-2014
Show Abstract
Hide Abstract
Glenoid component positioning is a key factor for success in total shoulder arthroplasty. Three-dimensional (3D) measurements of glenoid retroversion, inclination, and humeral head subluxation are helpful tools for preoperative planning. The purpose of this study was to assess the reliability and precision of a novel surgical method for placing the glenoid component with use of patient-specific templates created by preoperative surgical planning and 3D modeling.

Massive irreparable rotator cuff tears: how to rebalance the cuff-deficient shoulder.
Instr Course Lect
PUBLISHED: 04-12-2014
Show Abstract
Hide Abstract
In its natural state, the shoulder is unbalanced in both the vertical and horizontal planes because the deltoid is stronger than the rotator cuff muscles and the internal rotator muscles are stronger than the external rotator muscles. With aging, this muscle imbalance can become worse, leading to tendon wear, irreversible fatty infiltration of the rotator cuff muscles, and upward migration of the humeral head. Most shoulders with tendon wear are functional and asymptomatic. A traumatic event (such as a fall onto the upper limb) can lead to rotator cuff tearing and a shoulder that becomes symptomatic and nonfunctional. Symptomatic massive irreparable rotator cuff tears present in one of four recognizable patterns depending on the muscular imbalance that occurs and the symptoms that are present: painful loss of active elevation, with conserved muscle balance; isolated loss of active elevation, with loss of vertical muscle balance; isolated loss of external rotation, with loss of horizontal muscle balance; and combined loss of elevation and external rotation, with loss of vertical and horizontal muscle balance. Assessing the plane of shoulder muscle imbalance is a key feature in the decision-making process. Classifying and understanding these tears allows surgeons to select the correct treatment (conservative measures, arthroscopic techniques, reverse shoulder arthroplasty, or tendon transfers) to restore shoulder balance and function.

Hide Abstract
Bone metastases are detected at initial diagnosis of cancer in 25% of cases and bone metastases are common in the course of a majority of cancer types. The spine and proximal long bones are the most affected sites. Knowledge of the basic radiological semiology is important to make the proper diagnosis of metastasis(s) bone(s), especially in situations in which the clinical context is not suggestive of metastases (such as cases where bone metastases are inaugural or cases of peripheral solitary metastasis). Tumor aggressiveness can be assessed at the level of the cortical bone and periosteum. Lodwick criteria are useful for the diagnosis of malignancy and tumor aggressiveness at initial diagnosis on plain radiographs, which are very important in the context of bone metastases. A CT scanner is required to confirm the malignancy of a bone lesion. MRI is complementary to the scanner including for the assessment of bone marrow involvement and tumor extensions.

Percutaneous discectomy on lumbar radiculopathy related to disk herniation: why under CT guidance? An open study of 100 consecutive patients.

Hide Abstract
The primary objective of this study conducted on 100 patients is to demonstrate that performing CT-guided percutaneous discectomy for herniated disks results in a significant improvement in pain symptoms at several times (D1, D2, D7, 1 month, 3 months, 6 months). This objective assesses the effectiveness and feasibility of this technique under CT guidance in patients presenting documented lower back pain related to disk herniation that has not improved with appropriate medical treatment. The impact of various factors on the effectiveness of discectomy will also be evaluated. At 1 week, we notes a decrease in average VAS respectively of 71% and 67% in patients treated for posterolateral and foraminal herniated disks; the result for posteromedian herniated disks is only 45% in average decrease. At 6 months post op, 79% of lateralized herniated disks have a satisfactory result (? 70% decrease in pain as compared to initial pain), whereas post median herniated disks had a satisfactory result in only 50% of cases. Percutaneous fine needle discectomy probe under combined CT and fluoroscopic guidance is a minimally invasive spine surgery which should be considered as an alternative to surgery. This technique presents several advantages: the small diameter of the probe used (maximum 16 G or 1.5mm) allows a cutaneous incision of only a few millimeters, and a trans-canal approach can be possible; it also decreases the risk of ligamentary lesion and does not cause an osseous lesion of the posterior arc or of the adjacent muscular structures.

CT guided Transpedicular fixation could be a useful strategy in the treatment of future cases involving poorly healing pedicle fractures causing persistent symptoms. This intervention confirms the range of capacities of CT scan-controlled interventions in terms of precision, safety, speed, minimal invasiveness, rapid return to everyday activity and consequently, economical management.

Shoulder arthroplasty: evolving techniques and indications.

Hide Abstract
The development of modern shoulder replacement surgery started over half a century ago with the pioneering work done by CS Neer. Several designs for shoulder prostheses are now available, allowing surgeons to select the best design for each situation. When the rotator cuff is intact, unconstrained prostheses produce reliable and reproducible results, with prosthesis survival rates of 97% after 10 years and 84% after 20 years. In patients with three- or four-part fractures of the proximal humerus, the outcome of shoulder arthroplasty depends largely on healing of the greater tuberosity, which is therefore a major treatment objective. Factors crucial to greater tuberosity union include selection of the optimal prosthesis design, flawless fixation of the tuberosities, and appropriate postoperative immobilization. The reverse shoulder prosthesis developed by Grammont has been recognized since 1991 as a valid option for patients with glenohumeral osteoarthritis. Ten-year prosthesis survival rates are 91% overall (including trauma and revisions) and 94% for glenohumeral osteoarthritis with head migration. These good results are generating interest in the reverse shoulder prosthesis as a treatment option in situations where unconstrained prostheses are unsatisfactory (primary glenohumeral osteoarthritis with marked glenoid cavity erosion; comminuted fractures in patients older than 75 years; post-traumatic osteoarthritis with severe tuberosity malunion or nonunion; massive irreparable rotator cuff tears with pseudoparalysis; failed rotator cuff repair; and proximal humerus tumor requiring resection of the rotator cuff insertions).

Show Abstract
Hide Abstract
The all-arthroscopic technique that the authors propose combines a Bristow-Latarjet procedure with a Bankart repair. This combined procedure provides a triple blocking of the shoulder (the so-called 2B3 procedure): (1) the labral repair recreates the anterior bumper and protects the humeral head from direct contact with the coracoid bone graft (Bumper effect); (2) the transferred coracoid bone block compensates for anterior glenoid bone loss (Bony effect); and (3) the transferred conjoined tendon creates a dynamic sling that reinforces the weak anteroinferior capsule by lowering the inferior part of the subscapularis when the arm is abducted and externally rotated (Belt or sling effect). The procedure combines the theoretic advantages of the Bristow-Latarjet procedure and the arthroscopic Bankart repair, eliminating the potential disadvantages of each. The extra-articular positioning of the bone block together with the labral repair and capsule retensioning allows the surgeon to perform a nearly anatomic shoulder repair. This novel procedure allows the surgeon to extend the indications of arthroscopic shoulder reconstruction to the subset of patients with recurrent anteroinferior shoulder instability with glenoid bone loss and capsular deficiency. It is an attractive surgical option to treat patients with a previous failed capsulolabral repair for which the surgical solutions are limited.

Although a scoring system and other assessment tools can be useful, the choice of a surgical treatment for glenohumeral stabilization requires a careful assimilation of the patients expectations and the surgeons experience as well as an understanding of the relevant individual pathoanatomy. Pathoanatomy, nonsurgical and surgical treatment of shoulder instability, bone loss, unsuccessful stabilization treatment, and review of recent literature are important factors.

We hypothesized that a modified LEpiscopo procedure (latissimus dorsi [LD] and teres major [TM] transfer) with a simultaneous RSA would restore shoulder function and activities of daily living (ADLs).

Physiological partial aldosterone resistance in human newborns.
Pediatr. Res.

Show Abstract
Hide Abstract
In the neonatal period, the human kidney is characterized by an impaired ability to regulate water and sodium homeostasis, resembling partial aldosterone resistance. The aim of our study was to assess this hormonal insensitivity in newborn infants and to determine its relationship with neonatal sodium handling. We conducted a prospective study in 48 healthy newborns and their mothers. Aldosterone, renin, and electrolyte concentrations were measured in umbilical cords and in maternal plasma. Urinary aldosterone concentrations and sodium excretion were determined at urination within 24 h after birth. A significant difference was observed between aldosterone and renin levels in newborn infants compared with their mothers (817 +/- 73 versus 575 +/- 55 pg/mL and 79 +/- 10 versus 15 +/- 2 pg/mL, respectively, p < 0.001). This hyperactivation of the renin-angiotensin-aldosterone system was associated with hyponatremia and hyperkalemia in the newborn infants, and high urinary sodium loss, consistent with a partial aldosterone resistance at birth. Unlike plasma aldosterone, urinary aldosterone concentration was found highly correlated with plasma potassium concentrations, thus representing the best index for accurate evaluation of mineralocorticoid sensitivity. Our study represents a comprehensive characterization of the renin-aldosterone axis in newborn infants and provides evidence for physiologic partial aldosterone resistance in the neonatal period.

Hide Abstract
The human neonatal period is characterized by renal immaturity with impaired capacity to regulate water and sodium homeostasis, resembling partial aldosterone resistance. Because aldosterone effects are mediated by the mineralocorticoid receptor (MR), we postulated that this hormonal unresponsiveness could be related to low MR expression in the distal nephron. We measured aldosterone and renin levels in umbilical cord blood of healthy newborns. We used quantitative real-time PCR and immunohistochemistry to analyze the expression of MR and key players of the mineralocorticoid signaling pathway during human and mouse renal development. High aldosterone and renin levels were found at birth. MR mRNA was detected in mouse kidney at d 16 postcoitum, peaking at d 18 postcoitum, but its expression was surprisingly very low at birth, rising progressively afterward. Similar biphasic temporal expression was observed during human renal embryogenesis, with a transient expression between 15 and 24 wk of gestation but an undetectable immunoreactive MR in late gestational and neonatal kidneys. This cyclic MR expression was tightly correlated with the evolution of the 11beta-hydroxysteroid dehydrogenase type 2 and the epithelial sodium channel alpha-subunit. In contrast, glucocorticoid and vasopressin receptors and aquaporin 2 followed a progressive and sustained evolution during renal maturation. Our study provides the first evidence for a low renal MR expression level at birth, despite high aldosterone levels, which could account for compromised postnatal sodium handling. Elucidation of regulatory mechanisms governing MR expression should lead to new strategies for the management of sodium waste in preterms and neonates.

Secondary to the progress in interventional imaging, new therapeutic options have been developed that decrease potential complications because they are minimally invasive and they decrease patient rehabilitation time. As a diagnostic modality, computed axial tomography (CAT) allows precise evaluation of the degree of sacroiliac reduction that must be performed. Moreover, the use of CAT enables easy positioning of screws across the sacroiliac joint, thus avoiding nerve and vascular damage. We report our clinical experience of 20 patients treated by CAT-guided percutaneous fixation for posttraumatic unilateral sacroiliac disruption, including evaluation of our technique, its safety, and patient outcomes and long-term results. All patients in this study had successful outcomes, which were judged according to how much pain they experienced and how quickly they resumed normal activity after the procedure. Twelve of 16 patients were able to return to work by postoperative month 2. One patient had degenerative sacroiliac joint syndrome (5%), which was confirmed 6 months after surgery by CAT scan. None of the patients showed radiologic or clinical evidence of instability of the sacroiliac joint or screw migration. Postoperative follow-up, performed at 1, 2, and 3 years in our rehabilitation department, showed stable results over time. All pain disappeared, without the need for medication, in 19 patients (95%).

This enzyme is also expressed in the kidney, where it prevents illicit occupation of the mineralocorticoid receptor by glucocorticoids. We investigated the role of renal 11?HSD2 in the control of neonatal glucocorticoid metabolism in the human and mouse.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
