Abstract
BACKGROUND Extracorporeal shockwave therapy is a conservative treatment for several painful musculoskeletal disorders. The aim of the study was the assessment of the relief from pain by the shockwave therapy in a population of consecutive patients affected by specific pathologies. MATERIALS AND METHODS A group of consecutive patients were studied and treated. They were affected by calcific tendonitis of the shoulder (129 patients), chronic Achilles tendinopathy (102 patients), and lateral epicondylitis of the elbow (80 subjects). Each patient had 3 applications with a monthly interval, and was followed up at 1, 6, and 12 months after treatment. Results were evaluated by the numeric rating scale (NRS) in all cases, the Constant Murley Score for the assessment of the shoulder function, the American Orthopaedic Foot and Ankle Society Score for subjects affected by chronic Achilles tendinopathy, and the Oxford Elbow Score for those affected by a lateral epicondylitis of the elbow. RESULTS One year after treatment, the results were considered satisfactory with an almost complete resolution of symptoms. There were statistically significant results at the 12-month follow-ups regarding the mean NRS score (from 6.25 to 0.2), the Constant Murley Score (from 66.7 to 79.4), the Oxford Elbow Score (from 28 to 46), and the AOFAS (from 71 to 86). CONCLUSIONS Extracorporeal shockwave therapy may be considered a safe, economic, and effective treatment for several chronic musculoskeletal disorders, allowing satisfactory pain relief and improvement of function ability.

Abstract
BACKGROUND New bearing surfaces for total knee replacement have been described in an attempt to reduce polyethylene wear and secondary osteolysis and improve longevity of implants. Oxidized zirconium is a new material that combines the strength of a metal with the wear properties of a ceramic. However, there are no reports as to who documents the long term results. We report a 10 year follow-up note of a selected series of TKAs with an oxidized zirconium femoral component. METHODS We prospectively follow 98 TKAs performed in 94 patients with an oxidized zirconium femoral component. Five patients (5 knees) had died and 6 (6 knees) were lost to follow-up at a minimum of 2 years (mean, 6.3 years; range, 2-9 years) after the operation. For the remaining 83 patients (87 knees), the minimum follow-up was 10 years (mean, 11.3 years; range, 10.0-12.6 years). In 51 cases (58.6%), a cruciate-retaining implant with a deep-dished, more conforming PE was used, and in 36 cases (41.4%), a posterior-stabilized design was used. The patellae were resurfaced in 32 cases (36.7%) and in 55 cases (63.3%) were left unresurfaced. RESULTS Survivorship was 97.8% at 10 years postoperatively. Two knees were revised for aseptic loosening of the femoral component. No major complication was observed clinically or radiologically. Mean Knee Society score improved from 36 to 84 and functional score from 37 to 83. CONCLUSIONS Oxidized zirconium femoral component in TKA performs well over the first 10 years following implantation, with excellent survival rates and good clinical and radiological outcomes. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
The mechanism of membrane permeabilization by dermcidin (DCD-1L), an antimicrobial peptide present in human sweat, was investigated at a mercury-supported monolayer of dioleoylphosphatidylcholine (DOPC) or dioleoylphosphatidylserine (DOPS) and at a mercury-supported tethered bilayer lipid membrane (tBLM) consisting of a thiolipid (DPTL) with a DOPC or DOPS monolayer self-assembled on top of it. In an unbuffered solution of pH 5.4, DCD-1L is almost neutral and permeabilizes a DPTL/DOPS tBLM at transmembrane potentials, ϕtrans, which are physiological. In a pH 7 buffer solution DCD-1L bears two negative charges and has no effect on a DPTL/DOPC tBLM, whereas it permeabilizes a DPTL/DOPS tBLM only outside the physiological ϕtrans range; however, the presence of zinc ion induces DCD-1L to permeabilize the DPTL/DOPS tBLM at physiological ϕtrans values. The effect of zinc ions suggests a DCD-1L conformation with its positive N-terminus embedded in the lipid bilayer and the negative C terminus floating on the membrane surface. This conformation can be stabilized by a zinc ion bridge between the His(38) residue of the C terminus and the carboxyl group of DOPS. Chronocoulometric potential jumps from ϕtrans ≅ +160 mV to sufficiently negative values yield charge transients exhibiting a sigmoidal shape preceded by a relatively long "foot". This behavior is indicative of ion-channel formation characterized by disruption of DCD-1L clusters adsorbed on top of the lipid bilayer, incorporation of the resulting monomers and their aggregation into hydrophilic pores by a mechanism of nucleation and growth.

Abstract
OBJECTIVES To evaluate the short-term efficacy of muscle shortening manoeuvre (MSM), by inducing an increase in strength of the shoulder muscles, for the treatment of shoulder impingement syndrome (SIS). METHODS Sixty subjects (mean age: 58.6 years) with SIS were assigned to one of 3 different treatment interventions: 1) MSM: a series of fast accelerations in the upward direction was applied to the upper limb that was also submitted to forces acting in the opposite direction (added mass); 2) traditional physiotherapeutic technique: scapulothoracic gliding; 3) simple traction: the added mass was applied to the limb without the series of fast accelerations. Pain intensity, Neer's impingement sign, range of motion and muscle strength were assessed. Ultrasound (US) examination was performed before, immediately after and 30 days after each treatment to study the width of the subacromial-subdeltoid bursa, long biceps tendon sheath and acromioclavicular joint. Impingement was evaluated by dynamic examination. RESULTS After treatment with MSM, pain was significantly reduced (p<0.001), Neer's impingement sign was negative, range of motion and muscle strength were increased. US examination showed that the widths of the subacromial-subdeltoid bursa (p<0.001), long biceps tendon sheath (p<0.001) and acromioclavicular joint (p<0.001) were significantly reduced; impingement was no more detected. After 30 days, improvement in clinical and US findings was maintained. In the two control groups, no significant changes were observed after treatment. CONCLUSIONS Clinical and US findings demonstrate that MSM, by inducing an increase in muscle strength, is effective in the short-term treatment of SIS.

Abstract
BACKGROUND Elevation of the joint line frequently occurs in revision total knee arthroplasty (RTKA) because of a wider flexion space than extension space. One solution to balance this flexion-extension space involves the introduction of couplers between the stem and femoral components, and the use of posteriorly offset femoral stems that we hypothesized would improve gap balancing and facilitate joint line restoration. METHODS We retrospectively reviewed a selected series of 43 RTKA. Postoperative joint line height was subtracted from intended height using postoperative lateral radiographs. The value was negative if the joint line position was lowered, and positive if raised. RESULTS Forty knees were followed for a mean of 3.5years. Mean postoperative joint line position change from intended position was 1.5mm (range -2.5-7.5mm). In 28 knees (70%), the joint line position was restored to within ±2mm of the intended position; in eight knees (20%), from 2-4mm; and in four knees (10%), >4mm. Joint line position was raised in 32 knees (80%) and lowered in eight (20%). In the offset stem knees, the intended joint line position was 0.9mm (range -1.2-3.4mm) as compared with 3.2mm (range -2.5-7.5mm) for the straight stem knees. CONCLUSIONS A coupler system between the femoral stem and femoral component restored the joint line in 70% of cases. The posterior offset stem provided increased posterior condylar offset, addressed the wider flexion space, provided better positioning of the stem, and restored the joint line.

Abstract
BACKGROUND AND AIMS Proximal humerus is a common site of fracture in elderly patients, mainly related to bone fragility. Comorbidities are often present in these patients and may limit the surgical options. Not or minimal invasive treatments are commonly indicated however with variable results. The authors present their experience with conservative approach and percutaneous fixation by K-wires, focusing on their indications and main advantages on this population: mini-invasivity, acceptable reduction and recovery, and low costs. METHODS A study group of 51 consecutive patients with a mean age of 75.5 and affected by severe comorbidities (mainly cardiac, circulatory, pneumologic, neurologic, metabolic, and nephrologic pathologies) were evaluated clinically (ASA score, VAS, muscular strength, Constant-Murley score), and with radiologic analysis: 28 patients were treated by percutaneous fixation, while 23 subjects were treated conservatively. RESULTS Fractures treated by K-wires fixation healed after a mean interval of 8.2 weeks in all fractures but one, with improvements in mean Constant-Murley score (up to 80.6 points), in mean VAS (2.9), in muscular strength (4.1), and in range of motion. Fractures treated by brace healed in a mean time of 10.2 weeks. Mean Constant-Murley score improved to 76.4 points, VAS to 3.0, muscular strength to 3.8 points, and significant recovery of range of motion. CONCLUSIONS Results of the study confirm that both percutaneous fixation and conservative treatment may represent suitable options for proximal humerus fragility fractures in elderly patients, not candidated to open surgery for severe associated comorbidities.

Abstract
PURPOSE Total knee arthroplasty is one of the most successful procedures of modern orthopedics. Several implants have been proposed over the years with different designs, kinematics, and cementing techniques, with good results. The aim of the study was to assess the clinical and radiographic long-term follow-up of a series of patients undergoing total knee replacement that used a specific design of knee implant with cemented femoral and patellar components, and a hybrid fixation technique for tibial trays that used a cemented base plate and press-fit keels. METHODS A total of 145 implants in 135 patients were studied with clinical and radiologic evaluations. The mean follow-up was 17.1 years. RESULTS Seven failures for aseptic loosening and four failures for infection were registered. Twenty-nine implants showed nonprogressive radiolucencies, mostly at a single component, which did not need revision. The overall survivorship at the mean follow-up of 15 years considering aseptic loosening as the endpoint was 92.1%. CONCLUSIONS The authors confirm the good rates of success and the long-term survival of this specific implant and the effectiveness of the tibial hybrid cementing technique, which is still debated among researchers.

Abstract
Osteoarthritis of the hip is a common pathology and involves forms of disability and need for treatments that affect the quality of life of patients and their families, and in general of the whole society. It should be considered as such degenerative joint disease is increasing as the increase in life expectancy and musculoskeletal trauma, the latter responsible for secondary forms of osteoarthritis. The treatment of osteoarthritis of the hip has changed a lot over the years, since the earlier diagnosis and, before, with prevention through proper lifestyle. More in-depth knowledge of the biology of the tissues involved, first of all hyaline cartilage, has lead to non-surgical treatments such as infiltration with hyaluronic acid (viscosupplementation) and autologous growth factors derived from platelets (platelet rich plasma). Surgical therapy with prosthetic replacement is finally a choice to share with the patient based on pain and functional limitation, bearing in mind always the best technology and tribology and the possibility of less invasive surgical access, while recognizing that there are not still eternal prosthesis. Of particular importance then is the age of the patient. There are also other types of surgery (hip arthroscopy, forage) for other pathologies of the hip which can be resolutive, or, in a sense, can delay the arrival to the prosthetic replacement. We will discuss below the decision-making process that leads the surgeon with the patient to the surgery option.

Abstract
Several conditions in Orthopaedics and Traumatology are characterized by a bone loss. Bone auto- or allo-grafting was considered sufficient to fullfill the defects decades ago; however, large bone defects were challenging for the Surgeons, particularly in case of necessity of structural and biological properties. Bioindusrty proposed over the years synthetic biomaterials, as Demineralized Bone Matrix, bioactive surfaces for implant coponents, and recently recombinant Bone Morphogenetic Proteins. At the same time, the concept of the "biological chamber" and "diamond concept" allowed the scientific community to consider the need of a more complex interaction between scaffolds (matrix), cells (mesenchymal cells), and signaling (growth factors) in order to induce bone regeneration and also to fill small or large bone defects. A brief overview is made on the processes of a physiologic bone metabolism (induction, conduction, osteogenesis), on the latest therapeutical procedures, based on the use of autologous growth factors and cells, and the recent prosthetic or synthetic scaffolds, and the common clinical conditions that may beneficiate of these modern approaches.

Abstract
BACKGROUND Symptomatic severe osteoarthritis and hip osteoporotic fractures are the main conditions requiring total hip arthroplasty (THA), whereas total knee arthroplasty (TKA) is mainly performed for pain, disability or deformity due to osteoarthritis. After surgery, some patients suffer from "painful prosthesis", which currently represents a clinical problem. METHODS A systematic review of scientific literature has been performed. A panel of experts has examined the issue of persistent pain following total hip or knee arthroplasty, in order to characterize etiopathological mechanisms and define how to cope with this condition. RESULTS Four major categories (non infective, septic, other and idiopathic causes) have been identified as possible origin of persistent pain after total joint arthroplasty (TJA). Time to surgery, pain level and function impairment before surgical intervention, mechanical stress following prosthesis implant, osseointegration deficiency, and post-traumatic or allergic inflammatory response are all factors playing an important role in causing persistent pain after joint arthroplasty. Diagnosis of persistent pain should be made in case of post-operative pain (self-reported as VAS ≥3) persisting for at least 4 months after surgery, or new onset of pain (VAS ≥3) after the first 4 months, lasting ≥2 months. Acute pain reported as VAS score ≥7 in patients who underwent TJA should be always immediately investigated. CONCLUSIONS The cause of pain needs always to be indentified and removed whenever possible. Implant revision is indicated only when septic or aseptic loosening is diagnosed. Current evidence has shown that peri-and/or post-operative administration of bisphosphonates may have a role in pain management and periprosthetic bone loss prevention.
