#2
REVIEW
Costantino Errani, Shinji Tsukamoto, Andreas F Mavrogenis
Recent clinical studies have suggested that denosumab is associated with beneficial tumour response, surgical down-staging, and reduced surgical morbidity in patients with giant cell tumour of bone. However, these studies reported results of patients still on denosumab treatment, or patients after denosumab treatment but with a short follow-up. Other studies reported that the new osseous tumour matrix and thickened cortical bone that develop with denosumab treatment does not allow the surgeon to delineate the true extent of the tumour, and probably increases the risk for local recurrence...

PURPOSE: Management of proximal humeral tumours remains a surgical challenge. No study to date has assessed the quality of life scores following the composite reverse shoulder arthroplasty for this indication. We, therefore, evaluated function and quality of life following reconstruction with allograft for malignant tumour of the humerus. METHODS: A series of six cases of humeral tumour treated by a single surgeon in a single centre was reviewed after a mean follow-up of 5...

PURPOSE: The correlation between tibial tuberosity-trochlear groove distance (TT-TG) and joint size, taking into account several different parameters of knee joint size as well as lower limb dimensions, is evaluated in order to assess whether TT-TG indices should be used in instead of absolute TT-TG values. METHODS: This study comprised a retrospective analysis of knee CT scans, including 36 cases with patellofemoral instability (PFI) and 30 controls. Besides TT-TG, five measures of knee joint size were evaluated in axial CT slices: medio-lateral femur width, antero-posterior lateral condylar height, medio-lateral width of the tibia, width of the patella and the proximal-distal joint size (TT-TE)...

The purpose of this review article is to summarize the views presented in the Hippocratic Corpus of Medicine regarding injuries of the spine, their effect on the spinal cord and the optimal treatment modulus. It is shown that the treatment dilemmas of ancient times in these injuries remain modern since Hippocrates suggested that conservative treatment and letting nature take its course is preferable over a devastating surgical treatment if the spinal cord structural integrity is not compromised. There is also a detailed account of the conservative treatment suggested in the Hippocratic Corpus concerning devices and method of closed spinal relocations...

INTRODUCTION: Metal-on-metal (MoM) hip replacement bearings produce metallic ions that can cause health complications. Metallic release also occurs with other materials, but data on metallic ion levels after knee arthroplasty are sparse. We postulate that knee replacement generates elevating metallic ions (chromium (Cr), cobalt (Co) and titanium (Ti)) during the first year after implantation. PATIENTS AND METHODS: This ongoing prospective study included all patients who underwent the same type of knee arthroplasty between May and December 2013...

PURPOSE: Three-dimensional bioactive scaffolds are useful tools for stem cell implant in tissue-engineering. For chondral and subchondral repair, the chondroinductive and osteoinductive property of a scaffold is a major challenge. The scaffolds that aim to osteogenic differentiation have been well studied. However, cartilage cells can hardly be induced for osteogenesis, and monophase scaffolds cannot ideally repair both cartilage and subchondral defects at the same time. METHODS: We developed a novel biphase composite scaffold and observe its application osteochondral defects...

#15
REVIEW
Gregory Cunningham, Alexandre Lädermann
Many different types of impingements have been described in the shoulder. Inasmuch as the term 'shoulder impingement' usually refers to subacromial impingement, anterior impingement usually refers to subcoracoid impingement. However, there are many different subtypes of anterior impingements in the shoulder, and awareness of their existence is critical as they vary in their nature and treatment. Recent advances in biomechanical research and arthroscopic exploration of the anterior structures of the shoulder have brought new insights on the various potential impingements, warranting a revision and update of the current definitions of anterior shoulder impingement...

PURPOSE: We aimed to assess polyethylene liners of retrieved hips of one design of a dual mobility (DM) cup liner and two designs of femoral stems to better understand the role of femoral stem design on polyethylene impingement. METHODS: This was a case-control study involving 70 retrieved highly cross-linked polyethylene (X3) liners used with ABGII (n = 35) and Rejuvenate (n = 35) stems (Stryker). All polyethylene liners were assessed for evidence of rim deformation and the damage quantified using metrology methods...

INTRODUCTION: The aim of this study was to determine whether an above-elbow cast (AEC) is better than a below-elbow cast (BEC) at maintaining the initial reduction in the orthopaedic management of a distal radius fracture (DRF). METHODS: It is a prospective randomized study carried out in a single emergency trauma department. There were 72 patients older than 55 years of age (55-96) with a distal radius fracture treated orthopaedically. They were randomized into two groups: group B (AEC 32 patients) and group A (BEC 40 patients)...

BACKGROUND AND PURPOSE: Medial opening wedge high tibial osteotomy (MOWHTO) is a well-accepted procedure, which has been widely used for pain relief and varus deformity correction in the osteoarthritic (OA) knee, especially in the young patient. However, in the elderly patient, the efficacy of this procedure is still unknown. Therefore, this study aims to evaluate the survivorship of MOWHTO in elderly patients as the primary outcome. The secondary outcome is to evaluate the loss of correction angle that is the common complication after MOWTHO...

INTRODUCTION: Traditional open reduction and internal fixation (ORIF) of extra-articular distal humerus fractures has a risk of iatrogenic radial nerve injury, extensive soft tissue stripping, and long incision scar. We performed an antero-lateral minimally invasive plate osteosynthesis (MIPO) technique with the radial nerve exploration for distal-third diaphyseal fractures of the humerus and evaluated clinical and radiographic outcomes through this respective study. METHODS: From April 2010 to June 2016, 28 cases of extra-articular distal-third diaphyseal fractures were treated with an antero-lateral MIPO procedure...
