BMC Musculoskelet Disord 2020 Jul 2;21(1):424. Epub 2020 Jul 2.

Department of Mechanical Engineering, Korea University Engineering Campus, Innovation Hall, Room 306, Anam-dong, Seongbuk-gu, Seoul, 02841, South Korea.

Background: The role of altered joint mechanics on cartilage degeneration in in vivo models has not been studied successfully due to a lack of pre-injury information. We aimed 1) to develop an accurate in vivo canine model to measure the changes in joint loading and T2 star (T2*) relaxation time before and after unilateral supraspinatus tendon resections, and 2) to find the relationship between regional variations in articular cartilage loading patterns and T2* relaxation time distributions.

Methods: Rigid markers were implanted in the scapula and humerus of tested dogs. Read More

[Fracture diagnosis: upper extremities : Shoulder and shoulder girdle].

Radiologe 2020 Jun;60(6):541-548

Unfallchirurgische Klinik, Medizinische Hochschule Hannover, Hannover, Deutschland.

Background: The shoulder girdle is a chain of bones and joints which connect the upper extremity to the axial skeleton. The shoulder as a biomechanical unit has a remarkable range of motion and is therefore frequently prone to injuries of the three major joints (sternoclavicular joint, acromioclavicular joint, glenohumeral joint) and the bony elements (clavicle, scapula, humerus). Projection radiography is still the first imaging modality for injuries of the shoulder and usually sufficient for initial diagnosis and injury classification. Read More

Injured vs. uninjured elbow opening on clinical stress radiographs and its relationship to ulnar collateral ligament injury severity in throwers.

J Shoulder Elbow Surg 2020 May;29(5):982-988

Sports Medicine Center, Harvard Medical School at Massachusetts General Hospital, Boston, MA, USA.

Background: Stress radiography measures medial joint space opening of the elbow, but its value in the management of throwing athletes is unclear. The purpose of this study was to analyze the relationship between medial joint opening (gapping and excess opening) and ulnar collateral ligament (UCL) injury severity on magnetic resonance imaging, as well as to explore factors related to the unexpected finding of a greater opening of the uninjured elbow compared with the injured elbow (negative excess opening) with valgus stress radiography.

Methods: Medial joint space measurements were independently performed by 2 raters in a clinical series of 74 patients evaluated with standardized valgus stress radiography as part of their clinical workup for throwing-related medial elbow pain. Read More

Editorial Commentary: Bankart Lesion in an Adolescent Athlete? Not So Fast.

Arthroscopy 2020 02;36(2):345-346

With the desire to remain athletically competitive, many adolescent athletes with shoulder instability are turning to early surgical invention. But is surgical repair always necessary and are all Bankart lesions identical? Using 3-dimensional, frequency-selective, fat-suppressed gradient recalled echo magnetic resonance imaging (MRI) scans, the authors noted that the anterior glenoid rim secondary ossification center peaks at age 16 years in male patients but is only fused in 70% of male patients at age 17 years. Therefore, relying on MRI alone to guide surgical treatment may result in procedures that may otherwise be avoided because normal glenoid development may be mistaken for a bony Bankart lesion.

Editorial Commentary: Methodology of Measuring Bone Loss in Recurrent Shoulder Instability Surgery: Traditional Computed Tomography Scan and Magnetic Resonance Imaging Do Not Tell the Full Story.

Arthroscopy 2020 01;36(1):20-22

Steadman Philippon Research Institute.

When measuring bone loss in recurrent shoulder instability, both computed tomography (CT) scan and magnetic resonance imaging (MRI) are accurate using the circle method. However, measurement of on- versus off-track lesions can be inconsistent, and measuring Hill-Sachs lesions on MRI relative to an extrapolated rotator cuff attachment is difficult. In the end, determination of on- versus off-track treatment is quite difficult, and for this determination, differences between CT scan and MRI may be clinically imperceptible. Read More

The management of Salter-Harris type II fracture with associated posterior sternoclavicular joint displacement using a locking compression plate: A 14-year-old adolescent's case report.

Medicine (Baltimore) 2019 Dec;98(51):e18433

Department of Orthopedics and Traumatology, San Raffaele Scientific Institute.

Rationale: Posterior sternoclavicular joint dislocations (PSCJDs) are particularly rare injuries, accounting for 3% to 5% of sternoclavicular joint dislocations. With very few cases reported in the literature, these injuries are often misdiagnosed and imaging is not always clear, thus making physicians often unaware of them. The present case report aims to investigate a rare case involving a clavicular Salter-Harris II fracture with associated posterior displacement of the diaphysis, a term coined a "pseudodislocation.

Angle of approach to the superior rotator cuff of arthroscopic instruments depends on the acromial morphology: an experimental study in 3D printed human shoulders.

J Orthop Surg Res 2019 Dec 12;14(1):435. Epub 2019 Dec 12.

Department of Orthopaedics, Balgrist University Hospital, University of Zurich, Forchstrasse 340, CH 8008, Zurich, Switzerland.

Background: Portal placement is a key factor for the success of arthroscopic procedures, particularly in rotator cuff repair. We hypothesize that the acromial anatomy may strongly determine the position of the shoulder bony landmarks and limit the surgeon's freedom to position the arthroscopic approaches in direction towards the acromion. The purpose of this study was to analyze the relation between different acromial shapes and the freedom of movement of arthroscopic instruments relative to the rotator cuff from standardized arthroscopic portals in a laboratory study on 3D shoulder models.

Insights Imaging 2019 Oct 8;10(1):90. Epub 2019 Oct 8.

Radiology Department, Angers University Hospital, 4 rue Larrey, 49933, Angers, France.

Currently, an increasing number of patients benefit from shoulder prosthesis implantation. Radiologists are therefore more often confronted with imaging examinations involving shoulder arthroplasty, whether during a dedicated examination or incidentally. Standard radiography is the first-line imaging modality in the follow-up of these implants, before the possible use of cross-sectional imaging modalities (computed tomography and magnetic resonance imaging), ultrasound, or nuclear medicine examinations.

Effectiveness and safety of early intramuscular botulinum toxin injections to prevent shoulder deformity in babies with brachial plexus birth injury (POPB-TOX), a randomised controlled trial: study protocol.

BMJ Open 2019 09 30;9(9):e032901. Epub 2019 Sep 30.

Pediatric rehabilitation department, Fondation ILDYS, Brest, France.

Introduction: In children with brachial plexus birth injury (BPBI), denervation of the shoulder muscles leads to bony deformity in the first months of life, reducing active and passive range of motion (ROM) and causing activity limitation. The aim of this multicentre randomised controlled trial is to evaluate the effectiveness of botulinum toxin injections (BTI) in the shoulder internal rotator muscles of 12-month-old babies in limiting the progression of posterior subluxation of the glenohumeral joint, compared with a sham procedure mimicking BTI. The secondary aims are to evaluate the effectiveness of BTI in (1) limiting the progression of glenoid retroversion and three-dimensional (3D) deformity and (2) improving shoulder ROM and upper limb function, as well as to confirm the tolerance of BTI.
