Does Posterior Half-Wedge Augmented Glenoid restore version and alignment in Total Shoulder Arthroplasty for the B2 glenoid?

ConclusionsTotal shoulder replacement in B2 glenoid is technically demanding. Our radiological results show favourable outcome in terms of correction of gelenoid retroversion and eliminating posterior instability using wedge glenoid component.Level of EvidenceIV

This study aimed to elucidate the role of decorin, a small leucine ‐rich proteoglycan, in the degradation of cartilage matrix during the progression of post‐traumatic osteoarthritis (PTOA).MethodsThe destabilization of the medial meniscus (DMM) surgery was applied to 3 ‐month‐old decorin‐null and inducible decorin knockout mice to induce PTOA. The resulted OA phenotype was evaluated by assessing joint morphology and sulfated glycosaminoglycan (sGAG) staining via histology (n = 6/group), surface collagen fibril nanostructure via scanning electron microscopy (n = 4), tissue modulus via atomic force microscopy ‐na...

ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.

Whether bone–tendon healing is better facilitated by tendon fixation on a bone surface or within a tunnel is unknown. The purpose of this study was to comparatively evaluate the effects of bone surface versus bone trough fixation on bone–tendon healing in a rabbit patella–patellar tendon (PPT) injury model.MethodsThe rab...

Abstract BACKGROUND: The goals of lower limb reconstruction are to restore alignment, to improve function, and to reduce pain. However, it remains unclear whether alignment of the lower limb and hindfoot are associated because an accurate assessment of hindfoot deformities has been limited by superposition on plain radiography. Consequently, surgeons often overlook hindfoot deformity when planning orthopaedic procedures of the lower limb. Therefore, we used weight-bearing CT to quantify hindfoot deformity related to lower limb alignment in the coronal plane. QUESTIONS/PURPOSES: (1) Is lower-limb alignment dif...

J Knee Surg DOI: 10.1055/s-0039-3400741Anterior cruciate ligament (ACL) reconstruction represents one of the most successful orthopedic surgical procedures. Nevertheless, ACL revisions are still very frequent, with a small but relevant number of failures. The purpose of this study is to analyze the failure causes and the clinical outcomes of patients who underwent a re-revision ACL reconstruction. Between January 2009 and December 2017, 263 ACL revisions were performed by a single senior surgeon. Seventeen patients (12 males and 5 females) underwent re-revision ACL reconstruction meeting the inclusion criteria. The mean ag...

ConclusionsTo our knowledge, this is the first study to combine the cyclic compression and CEμCT scanning in the diffusion testing of human OA cartilage. This loading pattern could simulate the physiological conditions and reduce the time to reach solute equilibrium within cartilage. The diffusion data may contribute to joint drug-injection therapies for early OA.The translational potential of this articleThe combination of cyclic loading and CEμCT scanning enabled diffusion analysis of osteoarthritic cartilage under different compressions. A comprehensive evaluation of OA cartilage and subchondral bone may benefit f...

Semin Musculoskelet Radiol 2019; 23: 594-602 DOI: 10.1055/s-0039-1697940Clinical management of several pathologies of the lower extremity joint relies on instrumental imaging evaluation. The assessment of joint changes with physiologic load requires studies using positions with the patient standing. Weight-bearing radiographs are the mainstay for the evaluation of several conditions such as knee osteoarthritis, pes planus, and hallux valgus, in particular to obtain measurements of articular parameters, especially for presurgical studies. In the last few years, dedicated magnetic resonance imaging and computed tomography sc...

Rationale: Hereditary multiple exostoses (HME) is an autosomal dominant disease that causes multiple exostoses throughout the body. It usually occurs around the metaphysis of the long bones, and when it involves the hip, symptoms arise due to deformity and the mass effect. If the lesion does not involve the joint or is not associated with arthritis, symptoms can be relieved by surgical excision of the osteochondroma. However, if secondary osteoarthritis (OA) or subluxation of the joint has progressed, joint replacement arthroplasty should be considered. Patient concerns: A 57-year-old woman with HME visited our outpat...
