Shoulder stability depends on several factors, either anatomical or functional. Anatomical factors can be further subclassified under soft tissue (shoulder capsule, glenoid rim, glenohumeral ligaments etc) and bony structures (glenoid cavity and humeral head).Normal glenohumeral stability is maintained through factors mostly pertaining to the scapular side: glenoid version, depth and inclination, along with scapular dynamic positioning, can potentially cause decreased stability depending on the direction of said variables in the different planes. No significant factors in normal humeral anatomy seem to play a tangible role in affecting glenohumeral stability.When the glenohumeral joint suffers an episode of acute dislocation, either anterior (more frequent) or posterior, bony lesions often develop on both sides: a compression fracture of the humeral head (or Hill–Sachs lesion) and a bone loss of the glenoid rim. Interaction of such lesions can determine ‘re-engagement’ and recurrence.The concept of ‘glenoid track’ can help quantify an increased risk of recurrence: when the Hill–Sachs lesion engages the anterior glenoid rim, it is defined as ‘off-track’; if it does not, it is an ‘on-track’ lesion. The position of the Hill–Sachs lesion and the percentage of glenoid bone loss are critical factors in determining the likelihood of recurrent instability and in managing treatment.In terms of posterior glenohumeral instability, the ‘gamma angle concept’ can help ascertain which lesions are prone to recurrence based on the sum of specific angles and millimetres of posterior glenoid bone loss, in a similar fashion to what happens in anterior shoulder instability.Cite this article: EFORT Open Rev 2018;3:632-640.

Introduction:Given the importance of fracture healing on patient outcome in clinical practice, it is critical to assess fracture healing.Aim:The aim of this study was to evaluate the feasibility of the Radiographic Union Score Hip fracture after treatment with intramedullary nail of stable hip fractures.Patients and Methods:We retrospectively collected the data from the clinical records of our institution of the 47 patientswho had undergone intertrochanteric hip fracture treatment using an intramedullary nail. Pain visual analogic score (VAS) was collected the same day that X-rays were taken. Plain hip X-rays were performed, in two radiographic views, at 40 and 90 days after the surgical procedure. The correlation between the RUSH and VAS score was evaluated.Results:Mean RUSH and VAS scores showed a strong statistical improvement between the 40 and 90 day follow-ups. RUSH value at 40 days fitted an inverse linear regression with VAS, p-value of 0.0063 and r2 of 0.15. At 90 days the regression between RUSH and VAS scores was not significant.Conclusion:RUSH could be proposed as an objective system to evaluate union in hip fractures treated with intramedullary nail.
Introduction: Distal tibial fractures are the most common long bone fractures. Several studies focusing on the methods of treatment of displaced distal tibial fractures have been published. To date, locked plates, intramedullary nails and external fixation are the three most used techniques. The aim of our study was to compare intramedullary nail (IMN) and locked plate (LP) for treatment of this kind of fracture.Materials and methods: We collected data on 81 patients with distal tibial fractures (distance from the joint between 40 and 100 mm) and we divided into two groups: IMN and LP. We compared in the 2 groups the mean operation time, the mean union time, the infection rate the rate of malunion and nonunion, the full weight bearing time.Results: No patient in the two groups developed a nonunion. None of the patients obtained a fair or poor outcome. Overall 52 patients obtained an excellent result (69.3%) and 23 obtained a good result (30.6%).Discussion: Our study results indicate a superiority of IMN over LP in terms of lower rates of infections and statistically significant shorter time to full weight bearing. Whereas LP appeared to be advantageous over IMN in terms of leading to a better anatomical and fixed reductions of the fracture and a lower rate of union complications. The two treatments achieved comparable results in terms of operation time, hospital stay, union time and functional outcomes.
SummaryIntroduction. The aim of our study is to demonstrate the effectiveness of Steadman microfracture technique in the management of high-grade chondral defects at the level of the knee by clinical follow-ups at eleven years. It's essential to underline the importance of the single patient assessment process, taking into account a variety of aspects including the site, the number and extent of the lesion, the degree of functionality, activity level, age and previous trauma. This shows the importance of a comprehensive assessment of the patient in order to choose the most suitable surgical option, which not necessarily has to strictly adhere to standard practice.
