Cyst formation and bony ingrowth inside coil-type open-architecture anchors used for arthroscopic remplissage: a volumetric computed tomographic study of 50 anchors.

Background: The use of anchors in the proximal humerus during arthroscopic surgery can cause localized bone loss due to osteolysis and cyst formation. The purpose of this study was to use computed tomography (CT) to evaluate the incidence of implant-related bone loss and cyst formation after implantation of polyetheretherketone (PEEK) coil-type open-architecture anchors during remplissage for the management of Hill-Sachs defects (HSDs) in patients with shoulder instability.

Methods: This was a single-cohort, observational study with a minimum of 12 months of follow-up.

Force and Torque Characterization in the Actuation of a Walking-Assistance, Cable-Driven Exosuit.

Soft exosuits stand out when it comes to the development of walking-assistance devices thanks to both their higher degree of wearability, lower weight, and price compared to the bulkier equivalent rigid exoskeletons. In cable-driven exosuits, the acting force is driven by cables from the actuation system to the anchor points; thus, the user's movement is not restricted by a rigid structure. In this paper, a 3D inverse dynamics model is proposed and integrated with a model for a cable-driven actuation to predict the required motor torque and traction force in cables for a walking-assistance exosuit during gait.

Assessment of isolated glenohumeral range of motion in patients with adhesive capsulitis can help predict failure of conservative treatment: a pilot study.

Purpose: To prospectively evaluate a cohort of patients with adhesive capsulitis and identify predictors of failure of conservative treatment in the first 2 months of therapy.

Methods: This was a single-cohort, prospective observational study that included 20 participants (13 females/7 males; median age of 51.8 years [interquartile range: 8.

Vertebral instrumentation and Phlegmasia cerulea dolens.

Phlegmasia cerulea dolens is a very infrequent condition secondary to a deep venous thrombosis of multietiological origin usually affecting the lower extremities. It presents with pain and edema in the lower limb rapidly progressive that can compromise the perfusion of the limb, being able to cause gangrene, amputation and even death. We present an extremely rare case of a phlegmasia secondary to a massive deep venous tombosis of the left iliofemoral axis caused by chronic compressive hematoma of a traumatic origin due to a S1 screw shearing in a patient operated three months ago of a lumbar herniated disc through a L5-S1 fussion.

The absorbable subacromial spacer for irreparable posterosuperior cuff tears has inconsistent results.

Purpose: To evaluate the 2-year results of an absorbable subacromial spacer in patients with irreparable posterosuperior rotator cuff tears.

Methods: Prospective longitudinal study of a consecutive case series of 16 subjects with irreparable tears of the posterosuperior rotator cuff in which the InSpace subacromial spacer was arthroscopically implanted. A full clinical evaluation that included the Constant test, Simple Shoulder Test (SST) and the QuickDash questionnaire was performed preoperatively and at 12 and 24 months follow-up.

Lumbar Gout Tophus Mimicking Epidural Abscess with Magnetic Resonance Imaging, Bone, and Gallium Scans.

Gout is a common metabolic disorder, typically diagnosed in peripheral joints. Tophaceous deposits in lumbar spine are a very rare condition with very few cases reported in literature. The following is a case report of a 52-year-old patient with low back pain, left leg pain, and numbness.
