Abstract
Mesangiogenic Progenitor cells (MPCs) have been isolated from human bone marrow mononuclear cells (hBM-MNCs) and attracted particular attention for their ability to efficiently differentiate into exponentially growing mesenchymal stromal cells (MSCs) and toward endothelial lineage, suggesting the term "mesangiogenic". Coupling mesengenesis and angiogenis, MPCs has been hypothesized retaining a great tissue regenerative potential in musculoskeletal tissues regeneration. Bone marrow and adipose tissue (AT) represent most promising adult multipotent cell sources attempting to repair bone and cartilage, with controversial results regarding advantages applying BM- or AT-derived cells. As different culture determinants as well as tissue of origins, could strongly affect regenerative potential of cell preparations, we hypothesize that MPCs counterpart could have a role in defining efficacy of applying a cell-based medicinal product in musculoskeletal tissue repair. Here we present convincing data demonstrating that the ex vivo progenitors of MPCs are tissue specific and can be detected exclusively in hBM-MNCs.

Abstract
Gamma-glutamyltransferase (GGT) has been recently identified as a bone-resorbing factor. The aim of this study was to investigate the association between plasma GGT fractions levels and bone quality. Plasma GGT fractions were analysed by gel-filtration chromatography. Bone quality was established quantitatively by two micro-CT derived microarchitectural parameters: the BV/TV (mineralised bone volume/total volume), and the SMI (structure model index) that describes the rod-like (low resistant) or plate-like (high-resistant) shape of bone trabeculae. We enrolled 93 patients hospitalised for elective total hip replacement (group Arthrosis, n=46) or for proximal femoral fracture (group Fracture, n=47). Patients within the first quartile of BV/TV (Q1, osteoporotic patients, n=6) showed higher levels of b-GGT fraction [median (min-max): 3.37 (1.42–6.81)] compared to patients with normal bone density (fourth quartile Q4, n=10; 1.40 (0.83–4.36); p=0.0393]. Also, according to SMI, b-GGT value was higher in the subgroup with bone fragility [Q1, n=8: 1.36 (0.43–4.36); Q4, n=8: 5.10 (1.4 –7.60); p=0.0117]. In conclusion, patients characterised by fragile bone structure showed specifically higher levels of plasma b-GGT activity thus suggesting fractional GGT analysis as a possible biomarker in the diagnosis of osteoporosis.

Abstract
A successful Total Knee Arthroplasty (TKA) requires stability, but rarely in primary TKA, a prosthesis with more constraint than a posterior-stabilizer (PS) is necessary. In patients with severe varus/valgus deformities with incompetent collateral ligaments or in knees that cannot be adequately balanced after ligaments release, a total-stabilizer (TS) prosthesis may be required. The purpose of our retrospective study is to evaluate clinical and radiographic outcomes at short mid-term follow-up in patients treated with a TS TKA. Between January 2013 and August 2016, 36 patients (38 knees) were treated with Stryker Triathlon TS cemented implants. Clinical and radiographic evaluation were performed preoperatively and postoperatively at 1 month, 3 months, 6 months, 1 year and at 1-year intervals thereafter. At final follow-up, 33 patients (35 knees) remained and were included in this study and followed with a mean follow-up of 26.6 months. Clinical evaluation was performed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC score) and the Knee Society rating system that is subdivided into a knee score (KS) that rates only the knee joint itself and a functional score (FS). Knee Score (KS) and Functional Score (FS) increased significantly from a mean pre-operative value of 48 and 45, respectively, to a post-operative value at last follow-up of 86 and 82, respectively. Also WOMAC score improved significantly: the mean pre-operative WOMAC score was 45, while the mean post-operative WOMAC score, at last follow-up, was 19. The difference between pre- and post- operative results was significant at statistical analysis. In our opinion, when the adequately prosthesis balancing isn’t possible, because of primary or secondary severe varus/valgus deformity or severe soft tissues retraction, an available option is to perform a total knee arthroplasty with a total stabilizer polyethylene insert. TS prosthesis gives more stability during the most of ROM and, in addition, Triathlon system provides surgeons the possibility to choose a more constrained implant, than a standard PS one, during surgical procedure saving the bone stock. Our experience with this kind of prosthesis has provided good clinical and radiographic outcomes at a short mid-term follow-up with a low-rate of complications.

Abstract
PURPOSE The ageing of the population in developed countries has led to an increased number of patients with hip fractures all over the world. POSSUM and P-POSSUM scores predict morbidity and mortality of patients who will be undergoing a surgical treatment. The aim of this study was to evaluate accuracy of these two scores in hip-fractured patients. MATERIALS AND METHODS Between January and December 2012, in our department 144 patients were hospitalised for femoral neck fractures according to the grade III or IV of Garden's classification treated with total hip arthroplasty or endoprosthesis. POSSUM scores and P-POSSUM scores were calculated for each patient with complete clinical data. We then calculated the observed and the expected ratio. RESULTS 134 patients were eligible: 110 females and 24 males. The mean age for women was 79 years, and the mean age for men was 84 years. We observed 13 deaths and 66 complications. The POSSUM scores predicted 16 deaths and 60 complications, while P-POSSUM scores predicted 6 deaths. The O/E ratio for POSSUM mortality was 0.81 and for P-POSSUM was 2.17, while POSSUM morbidity was 1.1. CONCLUSION In our study, we have shown that on the one hand, the POSSUM score predicted accurately both the mortality and morbidity in patients undergoing surgery for the femoral neck fracture, while on the other hand, the P-POSSUM score underestimated them. For this reason, we believe that the POSSUM is indeed a good audit tool, which can accurately predict both mortality and morbidity in a cohort of patients.

Abstract
When a chondroma is localized in the superficial region of the bone it is defined periosteal or juxtacortical chondroma. This is a rare and benign cartilaginous lesion that more frequently affects males, and is generally observed in the tubular bones of the hand; it may, however, affect the other major bones, particularly the proximal end of the humerus. Age of onset is the second or third decade of life. Symptoms include moderate local pain. The clinical case presented here has two special features: the first is the site; based on an analysis of the international literature it seems that an analogous lesion at the level of the radial neck has not as yet been described; the second is the symptomatology that brought the patient to our attention.

Abstract
Ganglion cysts responsible for compression syndrome of the lower branch of the suprascapular nerve are described, but they are rare. The authors describe a well-documented case that was treated in a traditional manner by exeresis conducted through posterior access. Pain was relieved immediately, while force in external rotation and electromyographic findings improved as early as two months after surgery. One year after surgery the patient does not complain of the recurrence of symptoms. The literature is analyzed and therapeutic options available are discussed.
