Is total-body MRI useful as a screening tool to rule out malignant progression in patients with multiple osteochondromas? Results in a single-center cohort of 319 adult patients.

Purpose: To evaluate the results of total-body (TB) MRI used as a screening tool for assessment or exclusion of malignant transformation in patients with hereditary multiple osteochondromas (HMO).

Patients And Methods: In a single-institute cohort of MO patients, 366 TB-MRI examinations, including T1-weighted and STIR images, were performed for screening and follow-up purposes to rule out the malignant transformation, and retrospectively analyzed. In each patient, the presence and location of osteochondromas in the axial and appendicular bones were recorded.

Concurrent intraosseous cartilaginous lesions in patients with multiple osteochondromas identified on total-body MR imaging.

Purpose: To assess the prevalence of intraosseous cartilaginous lesions in patients with multiple osteochondromas based on total-body (TB) MRI examinations, used for screening purposes.

Subjects And Methods: Between 2013 and 2020, TB-MRI examinations were performed in 366 patients with proven multiple osteochondromas syndrome, to rule out malignant progression. For this study, presence, or absence of intraosseous central or eccentrical chondroid lesions, defined as lobulated lesions with low signal intensity on T1-weighted images, replacing bone marrow and high signal intensity equal to fluid on T2-weighted images in the bone marrow of the meta-diaphysis of (one of) the long bones, were recorded in the long bones as part of a TB-MRI protocol.

Shoulder arthroplasty volume standards: the more the better?

Introduction: The wide use of hip and knee arthroplasty has led to implementation of volume standards for hospitals and surgeons. For shoulder arthroplasty, the effect of volume on outcome has been researched, but no volume standard exists. This review assessed literature reporting on shoulder arthroplasty volumes and its relation to patient-reported and functional outcomes to define an annual volume threshold.

Radial head resection and hemi-interposition arthroplasty in patients with multiple hereditary exostoses: description of a new surgical technique.

Multiple hereditary exostoses (MHE) are a rare disorder characterized by the growth of bony protrusions. Elbow involvement is found in a considerable number of patients and varies from the presence of a simple osteochondroma to severe forearm deformities and radial head dislocation. Patients encounter a variety of symptoms, for example, pain, functional impairment, and cosmetic concerns.

Tips to avoid nerve injury in elbow arthroscopy.

Elbow arthroscopy is a technical challenging surgical procedure because of close proximity of neurovascular structures and the limited articular working space. With the rising number of elbow arthroscopies being performed nowadays due to an increasing number of surgeons performing this procedure and a broader range of indications, a rise in complications is foreseen. With this editorial we hope to create awareness of possible complications of elbow arthroscopy, particularly nerve injuries, and provide a guideline to avoid complications during elbow arthroscopy.

Multiple osteochondromas (MO) in the forearm: a 12-year single-centre experience.

Multiple osteochondromas (MO) are a rare autosomal dominant disorder characterized by the presence of osteochondromas located on the long bones and axial skeleton. Patients present with growth disturbances and angular deformities of the long bones as well as limited motion of affected joints. Forearm involvement is found in a considerable number of patients and may vary from the presence of a simple osteochondroma to severe forearm deformities and radial head dislocation.

Current concepts in the management of radial head fractures.

Fracture of the radial head is a common injury. Over the last decades, the radial head is increasingly recognized as an important stabilizer of the elbow. In order to maintain stability of the injured elbow, goals of treatment of radial head fractures have become more and more towards restoring function and stability of the elbow.

Efficacy of Different Rotator Cuff Repair Techniques.

The purpose of this review article is to describe the currently used techniques for rotator cuff repair and after treatment. The literature was searched for the different surgical techniques and additional treatment including: [1] full arthroscopic and arthroscopic assisted rotator cuff repair, [2] acromioplasty as an additional treatment to rotator cuff repair, [3] the use of plasma rich platelets (PRP) after rotator cuff repair, [4] the single and double row fixation techniques, [5] long head of the biceps brachii tenotomy or tenodesis with rotator cuff repair, [6] scaffolds in rotator cuff surgery, and [7] early motion or immobilization after rotator cuff repair. The rationale, the results, and the scientific evidence were reported for the eligible procedures.

Complex forearm deformities: operative strategy in posttraumatic pathology.

Complex posttraumatic forearm deformities have a significant impact on the integrity of the upper extremity leading to pain, instability in both the proximal and/or distal radioulnar articulation, and reduced range of forearm motion. Corrective osteotomy or more advanced procedures for malunited fractures or other posttraumatic deformities of the upper extremity, especially in the forearm are challenging procedures. In this review we will discuss the essential aspects of anatomy and pathomechanics, clinical and radiological assessment and the pathway from preoperative planning to the actual deformity correction surgery, either with one-stage correction or using gradual lengthening with external fixation ("callotasis techniques") and finally the functional outcome we can expect for our patients.
