“…68 Some studies limit passive forward elevation to 90, whereas others allow passive ROM flexion to gradually increase as tolerated or "within the limits of stability and soft tissue tension determined intraoperatively." 3,8,11 The SSc has been shown to retain its native level of passive tension with flexion or scaption in cadaveric studies following ATSA with variable humeral head component size, 71 though cadaveric studies do not reflect the pain and swelling present in a postoperative patient.…”

“…The ASSET practice pattern survey reached consensus at allowing 120° of elevation without differentiation of SSc takedown method. As cadaveric research has demonstrated no strain on the SSc during elevation following arthroplasty, 71 the ASSET recommendation for elevation in phase 1 allows passive motion to 120° while stressing the importance of avoiding undue force or overpressure. Isolated glenohumeral motion with scapular blocking should be avoided at this stage of recovery so that scapulohumeral rhythm can occur naturally, thereby avoiding strain on the healing SSc tendon.…”

Anatomic total shoulder arthroplasty is the gold standard shoulder replacement procedure for patients with an intact rotator cuff and sufficient glenoid bone to accommodate prosthetic glenoid implant and offers reliable patient satisfaction, excellent implant longevity, and a low incidence of complications. Disparity exists in the literature regarding rehabilitation strategies following anatomic total shoulder arthroplasty. This article presents a consensus statement from experts in the field on rehabilitation following anatomic total shoulder arthroplasty. The goal of this consensus statement is to provide a current evidence-based foundation to inform the rehabilitation process after anatomic total shoulder arthroplasty. These guidelines apply to anatomic total shoulder arthroplasty (replacement of the humeral head and glenoid), hemiarthroplasty (replacing only the humeral head), and hemiarthroplasty with glenoid reaming or resurfacing. The consensus statement integrates an extensive literature review, as well as survey results of the practice patterns of members of the American Society of Shoulder and Elbow Therapists and the American Shoulder and Elbow Surgeons. Three stages of recovery are proposed, which initially protect and then gradually load soft tissue affected by the surgical procedure, such as the subscapularis, for optimal patient outcomes. The proposed guidelines should be used in collaboration with surgeon preferences and patient-specific factors.

“…The range of motion of each lumbar unit (L3/4, L4/5 and L5/S1) was calculated by using the aluminium markers in Geomagic Studio software. Meanwhile, a common 3D motion-analysis system 17 , 18 was used to evaluate the range of motion of each lumbar unit with the same moment. All the data were expressed as mean ± standard deviation ( sd ).…”

The segment-dependent changes in lumbar intervertebral space height during flexion-extension motion

ObjectivesMany studies have investigated the kinematics of the lumbar spine and the morphological features of the lumbar discs. However, the segment-dependent immediate changes of the lumbar intervertebral space height during flexion-extension motion are still unclear. This study examined the changes of intervertebral space height during flexion-extension motion of lumbar specimens.MethodsFirst, we validated the accuracy and repeatability of a custom-made mechanical loading equipment set-up. Eight lumbar specimens underwent CT scanning in flexion, neural, and extension positions by using the equipment set-up. The changes in the disc height and distance between adjacent two pedicle screw entry points (DASEP) of the posterior approach at different lumbar levels (L3/4, L4/5 and L5/S1) were examined on three-dimensional lumbar models, which were reconstructed from the CT images.ResultsAll the vertebral motion segments (L3/4, L4/5 and L5/S1) had greater changes in disc height and DASEP from neutral to flexion than from neutral to extension. The change in anterior disc height gradually increased from upper to lower levels, from neutral to flexion. The changes in anterior and posterior disc heights were similar at the L4/5 level from neutral to extension, but the changes in anterior disc height were significantly greater than those in posterior disc height at the L3/4 and L5/S1 levels, from neutral to extension.ConclusionsThe lumbar motion segment showed level-specific changes in disc height and DASEP. The data may be helpful in understanding the physiologic dynamic characteristics of the lumbar spine and in optimising the parameters of lumbar surgical instruments.Cite this article: M. Fu, Q.

“…La flexion et l'abduction sont donc limitées à 90° et la rotation latérale (RL) à 0° et on évitera de solliciter activement l'épaule en rotation médiale (RM). 7 La mobilisation en actif-assisté (figure 4), ainsi que l'autorééducation avec un travail infradouloureux et progressif en pendulaire (figure 5), actif-assisté (figure 6), ou actif (figure 7) sont primordiales. Une utilisation progressive du membre supérieur dans les AVQ légères est conseillée, afin de favoriser l'autonomie et d'éviter le développement d'une kinésiophobie (peur du mouvement).…”

Rééducation après prothèses totales de l'épaule anatomique et inverséeCet article présente la rééducation après prothèses totales d'épaule anatomique (PTEa) et inversée (PTEi), qui se découpe en 3 phases : cicatrisation et initiation du mouvement (semaines 0-6), récupération du mouvement (7-12), renforcement et retour à l'activité (13)(14)(15)(16)(17)(18). Après 6-12 mois, la plupart des patients rapportent une nette diminution des douleurs et une reprise des activités légères à modérées. La rééducation de la PTEi implique spécifiquement de renforcer le muscle deltoïde et de prévenir la luxation. Le résultat fonctionnel est légèrement inférieur pour la PTEi, qui est posée lorsque des lésions musculo-tendineuses sont associées à des lésions osseuses, mais la satisfaction est comparable entre les deux types d'implants. La longévité de ces prothèses, bien que plus courte chez le patient actif jeune, est généralement bonne. Update on the rehabilitation following anatomic and reverse total shoulder arthroplastyThis article aims to present the principles of rehabilitation following anatomical and reverse total shoulder arthroplasties. The rehabi litation consist of three phases: wound healing and movement initiation (weeks 06), movement recovery (712), strengthening and return to activity (1318). At 6 to 12 months followup, most patients report a substantial decrease in pain and a return to light to moderate activity level. The rehabilitation of the reverse arthroplasty specifically requires deltoid muscle strengthening and dislocation prevention. The functional outcome is slightly inferior for reverse arthroplasty, which is indicated when musculotendinous lesions are associated to bone lesions, but satisfaction rates are comparable between the two types of implants. The durability of total shoulder arthroplasties is globally satisfying, though shorter in young active patients. L'information (suites et précautions postopératoires, mise en place du gilet et exercices à domicile) est importante afin de permettre une sortie de l'hôpital en toute sécurité. 8 Une fiche à l'attention des patients opérés d'une PTEa est présentée dans l'annexe 1, et une version en ligne (cf. annexe 1) est disponible pour les éléments spécifiques à la PTEi. 9-11 ROBIN PHILIPPOSSIAN a , Dr FRANÇOIS LUTHI a,b , Pr ALAIN FARRON a et Pr HES CLAUDE PICHONNAZ a,c
