Proximal humeral multiple fragment fractures in patients over 55: Comparison between Conservative treatment and Plate Fixation.

Proximal humerus fractures account for about 5% of fragility fractures. These involve a significant burden of disability and a reduced quality of life. This study aims to compare functional results and surgical outcomes (closed reduction and internal fixation with the internal closure system of the proximal humerus) and the conservative management of proximal humerus fractures by 2-, 3-, 4-parts, in patients older than 55 years. Between January 2017 and April 2019, 65 patients with 2, 3 or 4-part fractures were retrospectively analyzed: 29 patients (5 males and 24 females) with an average age of 70.8 ± 9.9 years treated non-surgically (conservative group (CG)) and 36 patients (11 males and 25 females) with an average age of 66.2 ± 7.1 years treated surgically with plate fixation (operating group (OG)). Using different evaluation scores, we compared the OG and the CG. Through the DASH score we have seen how at 12 months there is a satisfactory result in patients with conservative treatment (p = 0.0019). Constant-Murley scale shows no difference between the two treatments (p = 0.2300). BARTHEL scale and SST score did not give statistically satisfactory results. Also, after one year of follow-up, patients treated with conservative therapy had a higher improvement in their Range of Motion (ROM) values than patients treated with surgical treatment. The results in terms of pain in NPRS at 3, 6, 12 months are better for conservative groups (p = 0,0000). Our findings suggest that conservative treatment in proximal humeral fractures, particularly in multi-fragmented fractures in patients over 55 years of age, designs an excellent alternative to the surgical option.

High degree of consensus on diagnosis and management of rotator cuff tears: a Delphi approach.

PURPOSE: To develop a consensus on diagnosis and treatment of rotator cuff tears. The study focused on selected areas: imaging, prognostic factors, treatment options, surgical techniques. METHODS: Panel was composed of all members of the shoulder committee of the Italian Society of Arthroscopy, Knee, Upper arm, Sport, Cartilage and Orthopedic techniques (SIAGASCOT). Four rounds were performed. The first round consisted of gathering questions which were then divided into seven blocks referring to: imaging, patient-related prognostic factors, treatment options, surgical steps, reparative techniques, surgical predictive factors, advanced techniques. Subsequent rounds consisted of condensation by means of online questionnaire and debates. Consensus was defined as two-thirds agreement on one answer. Descriptive statistic was used to summarize the data. RESULTS: Forty-one shoulder experts were involved. Fifty-six statements were finally formulated. A consensus could be achieved on 51. Experts agreed that preoperative magnetic resonance imaging is strongly recommended because it allows a careful evaluation of tear characteristics, while the role of US remains debatable. Controversial patient-related factors such as age, comorbidities, smoking and stiffness do not contraindicate the repair. From a surgical standpoint, the experts highlighted that pseudo-paralysis is not a contraindication to rotator cuff repair. Consensus on specific surgical steps was also achieved: capsular release should be performed only in stiff shoulders; footprint preparation is mandatory, while debridement of tendon edges is not essential. If necessary, a rotator interval release could be performed without interrupting the continuity between subscapularis and supraspinatus tendon; posterior delamination should be always included in the repair. Advanced techniques such as tendon transfers should be selected based on the main clinical deficit, while the superior capsule reconstruction plays a role only in combination with a functional repair. CONCLUSION: A consensus was achieved almost on every topic of controversy explored. Particularly, MRI was deemed necessary to determine tear characteristics, while radiographs remain important for differential diagnosis; age should not be considered a contraindication to surgery; pseudo-paralysis does not represent a contraindication to arthroscopic rotator cuff repair, but superior capsule reconstruction plays a role only in combination with a functional repair. Latissimus dorsi transfer plays a role when the main functional deficit is in elevation, while the lower trapezius transfer plays a role when the main functional deficit is the external-rotation.

Clinical outcomes and recurrence rate of 4 procedures for recurrent anterior shoulder instability: ASA, remplissage, open, and arthroscopic Latarjet: a multicenter study.

BACKGROUND: The aim of the present study was to compare the clinical outcomes of 4 surgical techniques in patients with recurrent anterior shoulder dislocation, glenoid bone loss (GBL) <15% and Instability Severity Index (ISI) score >3. METHODS: A retrospective multicenter study was conducted on 226 patients who underwent 1 of 4 different techniques (Bankart plus arthroscopic subscapularis augmentation (ASA), Bankart plus remplissage, Latarjet, Arthro-Latarjet). The inclusion criteria were: recurrent dislocation, GBL <15%, and ISI score >3. The exclusion criteria were: GBL >15%, voluntary instability, multidirectional instability, preexisting osteoarthritis, throwing athletes' first dislocation, and ISI score<3. Follow-up ranged from 24 months to 6 years. Hyperlaxity was clinically evaluated according to Neer and Coudane-Walch tests. Clinical outcomes were assessed using the Rowe score and the Western Ontario Shoulder Instability Index (WOSI) for each technique. Before surgery, all patients underwent magnetic resonance imaging and computed tomography scanning. The Pico area method was used to assess the percentage of GBL. The operations were performed by 10 experienced surgeons; the functional outcomes were evaluated by 2 independent observers. RESULTS: A total of 226 patients who met the inclusion criteria were included in the present series. A total of 89.2% of patients in the ASA group reported an excellent Rowe score at the final follow-up, and their scores on the WOSI scale, improved from 838 to 235 points. A total of 79.9% of patients in remplissage (R) group reported an excellent Rowe score at the final follow-up, and their scores on the WOSI scale improved from 1146 to 465 points. A total of 98.5% of patients in the Latarjet (L) group reported an excellent Rowe score at the final follow-up, and their scores on the WOSI scale improved from 1456 to 319 points. A total of 81.6% of patients in the Arthro-Latarjet (AL) group reported an excellent Rowe score at the final follow-up, and their scores on the WOSI scale improved from 1250 to 221 points. The recurrence rates were as follows: ASA group (7%), remplissage group (6.1%), L group (1.5%), Arthro-Latarjet group (0%). Patients in the open L group had 15.5% (10/66) more complications. CONCLUSION: The use of ASA and remplissage to augment the Bankart repair have been demonstrated to be effective for restoring joint stability, yielding good clinical outcomes similar to the L procedure in patients affected by recurrent anterior dislocation with GBL <15% and an ISI score score >3. Soft tissues augmentations of the Bankart repair have been demonstrated to be effective for addressing anterior soft tissue deficiency dysfunction and critical Hill-Sachs lesions.

Arthroscopic Hill-Sachs Filling Technique Using an Absorbable Interference Screw.

We present an arthroscopic technique used to treat traumatic shoulder instability in the patient with a Hill-Sachs lesion, especially an off-track lesion. The incidence of this bony defect is approximately 40% to 90% of all anterior shoulder instability cases-and up to 100% in patients with recurrent anterior instability. Incorrect management of this humeral bone defect can lead to treatment failure, and it is essential to define characteristics such as the lesion's location, depth, width, and orientation. Many arthroscopic and open procedures have been described for the surgical management of the Hill-Sachs lesion. Using arthroscopy for the surgical treatment of shoulder instability offers numerous advantages. We describe an arthroscopic technique that consists of filling the Hill-Sachs lesion with absorbable interference screws made out of an advanced biocomposite material. After repair of the Hill-Sachs lesion, the Bankart lesion is repaired. As these screws are resorbed by bone tissue over several months, the bony anatomy is restored.

Arthroscopic reduction and subscapularis remplissage (ARR) of chronic posterior locked shoulder dislocation leads to optimized outcomes and low rate of complications.

PURPOSE: Unrecognized posterior shoulder dislocation with a concomitant humeral head fracture affects joint function and no consensus exists regarding treatment. The present study analyses clinical and radiographic outcomes of a novel arthroscopic technique for reducing chronic locked posterior shoulder dislocation associated with subscapularis remplissage. METHODS: The study comprises a retrospective analysis of consecutive chronic posterior locked shoulders (CPLS) with minimum 2-years follow-up of patients who had undergone McLaughlin technique arthroscopic modification for the treatment of CPLS with a reverse Hill-Sachs lesion. Active range of motion (ROM), Western Ontario (WOSI) and Constant Score (CS), were evaluated pre- and postoperatively. Plain radiographs and magnetic resonance imaging (MRI) scans were collected pre- and post-operatively, recording bone defect, osteoarthritis, cuff integrity/fatty infiltration, and the grade of filling of the reverse Hill-Sachs. RESULTS: Twelve male patients with a mean follow-up of 37.3 months ± 10.5 (range, 24-58) were included. Mean WOSI and CS scores improved from 41 to 92 and 28 to 94 points, respectively. ROM measurements all had significantly increased at final follow-up, with no significant differences in arm rotation. No defects were left unfilled at final MRI examination. CONCLUSION: The results of this uncontrolled study with a limited number of patients confirm that arthroscopic reduction and subscapularis remplissage is a highly effective and satisfactory treatment method resulting in no shoulder rotation deficits. LEVEL OF EVIDENCE: Level IV.

An Evolution of Shoulder Periprosthetic Infections Management: MicroDTTect, Bioactive Glass and Tantalum Cones Employment.

Periprosthetic joint infections of the shoulder (PJIS) are the major cause for revision within the first two post-operative years, and are challenging both to diagnose and treat. Success depends on early identification of microorganisms, appropriate surgical procedures and efficient antibiotic administration. The peculiar microbiology of the shoulder may render the criteria for hip/knee PJI management inappropriate. In addition, later cases with clinically subtle signs often present diagnostic challenges. In recent years, specific issues of PJIS have been managed through the use of new instruments, such as MicroDTTect in pathogen detection and Bioactive Glass and tantalum cones in humeral bone loss. In the literature to date, no reports have been found that discuss the application in shoulder revisions and infections. The early identification of the microorganisms that cause infection may help improve both treatment strategies and the efficacy of therapy. MicroDTTect proved to be more efficient than swab collection for bacterial identification in orthopedic surgery, thus reducing analysis costs. The increasing number of shoulder arthroplasties is associated with an increase in the number of revisions. In cases of massive metaphyseal humeral bone loss, several techniques have been described; no reports have been reported regarding tantalum in humeral bone loss management. In some cases the tantalum cones required adaptation for femoral diaphysis in the augmentation of the humerus metaphysis and bone loss management improvement. Obtaining stable osseointegration of prosthetic implants is one of the greatest issues in orthopedic surgery, and even more crucial in revisions. Bioactive glasses demonstrated good regenerative and osseointegration properties, and an excellent candidate as a bone graft, scaffold and antibiotics deliverer. The Bioactive glasses were used to increase prosthesis-bone interface stability and fill bone defects in PJIS revision surgeries, contributing to the prevention of re-infection. Longer-term follow-up will be necessary to determine if construction durability is improved in the long term.

Onlay Uncemented Lateralized Reverse Shoulder Arthroplasty for Fracture Sequelae Type 1 with Valgus/Varus Malunion: Deltoid Lengthening and Outcomes.

The successful treatment of proximal humeral fractures remains challenging for shoulder surgeons, and failure rates are high, regardless of initial treatment. This study aimed to analyze the clinical and radiographic midterm results of onlay lateralized cementless stem reverse shoulder arthroplasty (RSA) in patients with valgus/varus malunion proximal humerus fracture sequelae without metaphyseal osteotomy. We retrospectively studied 35 cases with the diagnosis of fracture sequelae of the proximal part of the humerus with valgus/varus malunion. The mean duration of follow-up was 4.6 years (range, 2 to 7 years), and the mean time between fracture and arthroplasty was 6 years (1 to 32 years). Seventeen patients (48.6%) had initially been treated nonoperatively. The Constant score (CS), active range of motion, and radiographs of the affected shoulders, as well as the acromion to greater tuberosity (AGT) distance and deltoid length (DL), were analyzed before surgery and at their latest follow-up. A total of thirty-three patients (94.3%) rated their outcome as very good or good. Mean CS, forward flexion, and external rotation improved significantly (p < 0.0001), as did internal rotation and pain (p < 0.05). AGT distance significantly increased postoperatively from 14.7 to 43.3 mm, as did DL from 143 to 170 mm (p < 0.05). There was no correlation between the outcomes and valgus/varus deformity, previous surgeries, or AGT distance/DL. A total of four complications occurred (11.4%): two dislocations were detected (5.7%) and successfully revised with a longer cemented stem. Onlay lateralized uncemented stem RSA improves clinical outcomes and decreases complications when treating valgus/varus malunion fracture sequelae, avoiding intraoperative technical challenges, such as tuberosities osteotomy conscious of bone loss and proper deltoid tensioning.

The Infinity-Lock System for Chronic Grade III AC Joint Dislocation: A Novel Technique, Rehabilitation Protocol and Short Term Results.

BACKGROUND: the choice of treatment of chronic grade III acromioclavicular (AC) joint dislocation is controversial. Several surgical techniques have been described in the literature, responding differently to nonoperative treatment. The aim of this study is to describe a modified technique of stabilizing an AC joint dislocation with the new Infinity-Lock Button System, in order to demonstrate that it is effective in optimizing outcomes and decreasing complications. METHODS: this is a retrospective study of 15 patients who underwent surgical stabilization of the AC joint dislocation between 2018 and 2019, through modified surgical technique using the Infinity-Lock Button System. Active range of motion (ROM), Specific Acromio Clavicular Score (SACS) and Constant Score (CS) were evaluated preoperatively and postoperatively at last 18 months follow up. Patients rated their outcomes as very good, good, satisfactory, or unsatisfactory. RESULTS: a total of twelve patients rated their outcome as very good and three as good; no patients were dissatisfied with surgery. The mean Constant Score increased from 38 points preoperatively to 95 postoperatively, the average SACS score decreased from 52 points preoperatively to 10 postoperatively, both significantly. No complications were detected. CONCLUSION: the described technique is effective for treatment of chronic grade III AC joint dislocation, resulting in elevated satisfaction ratings and predictable outcomes. Nevertheless, further longer term follow-up studies are required.

Experience-optimised fast track improves outcomes and decreases complications in total knee arthroplasty.

PURPOSE: The aim of this study was to describe an advanced total knee arthroplasty (TKA) fast-track programme and determine discharge parameters during hospitalisation, as well as patient satisfaction, outcomes and complications within the first 12 months after surgery. METHODS: This prospective study was based on patients selected consecutively for primary elective TKA, undergoing surgery between 2014 and 2017 in an established fast-track setting. Hospitalisation-related parameters were collected: demographics, body mass index (BMI), surgical time, ischaemia time, haemoglobin values, blood transfusions, length of stay, weight-bearing and stair-climbing time, opioid administration, preoperative and discharge loss of extension and maximum active flexion of the knee, visual analogue scale (VAS), 12-month follow-up satisfaction rate and range of motion, any complications, hospital re-admission and re-operation within the first 12 months. Differences were determined using t-tests. RESULTS: A total of 704 total knee replacements implanted in 481 patients were included in the study and 223 patients had a bilateral TKA. Their mean age was 69.8 years (range 57-88 years). At the 12-month follow-up, 623 patients (88.5%) reported being satisfied or very satisfied and 15 (2.1%) were dissatisfied with their TKA, mean active flexion and loss of extension were 104.4° and 2.3°, respectively. A total of 15 complications occurred (two percent): five painful knees, three knee stiffness, three haematomas, two infections, one hospital re-admission and one deep venous thrombosis. No cases of pulmonary embolism and death related to surgery were reported. CONCLUSION: The study reports on an advanced fast-track programme for TKA with a low incidence of surgery- and hospitalisation-related issues and complications and without any severe adverse events during the first year. On average, the fast-track programme had a short length of stay, an early recovery of weight-bearing, knee mobility, pain control and a high satisfaction rate, accompanied with an acceptable 12 month range of motion.

Reverse shoulder arthroplasty patient personalized rehabilitation protocol. Preliminary results according to prognostic groups.

BACKGROUND: Rehabilitation after Reverse Shoulder Arthroplasty (RSA) is still object of discussion with no based evidence guidelines. The aim of this study was to test a personalized rehabilitation protocol for three different patients groups according to clinical and intraoperative parameters that can affect final outcomes after RSA. PATIENTS AND METHODS: We retrospectively evaluated a consecutive series of 112 patients who underwent to RSA between 2013 and 2015. The average follow-up was 29.2 months. A preoperative and postoperative clinical and radiographic assessment was performed. According to clinical, radiographic and intraoperative parameters, we selected three groups dedicating each one a specific level of post surgical care. RESULTS: A statistically significant improvement was achieved from preoperative evaluation, regarding all analysed parameters. Notable improvements were reported in high care group: elevation improved of 63.9° despite of Group A 55.5° and Group B 54.5° and it resulted statistically significant (p< 0.05). Costant Score increased of 35.9%, despite of Group A and Group B respectively 40.6% and 34.8% (p> 0.05). CONCLUSION: Our study shows that a personalized rehabilitation protocol can be effective improving clinical outcomes and decreasing complications rate, particularly in difficult management patients. LEVEL OF EVIDENCE: Therapeutic Level IV.

Clinical evidence of traditional vs fast track recovery methodologies after total arthroplasty for osteoarthritic knee treatment. A retrospective observational study.

BACKGROUND: During the last years, programs to enhance postoperative recovery and decrease morbidity after total knee arthroplasty, have been developed across a variety of surgical procedures and referred to as "Fast-Track Surgery". In this study we aimed to find some answers in the management of osteoarthritic patients subjected to total knee arthroplasty, by using the Fast-Track methodology. To this purpose we evaluated parameters such as early mobilization of patients, better pain management, bleeding, possible complications, reduced hospitalization time, an overall improved recovery and patient satisfaction. METHODS: 132 patients were selected, of which, 95 treated with "Fast Track" method and 37 treated with traditional method (control group). All the patients were hospitalized and underwent the same rehabilitation program for the first three days after surgery. RESULTS: In both groups, the parameters of pain and deformity demonstrated the most rapid improvement, while those of function and movement were normalized as gradual and progressive improvement over the next 2 months. The different functional test used (Barthel, MRC, VAS) showed that the mean values were significantly greater in Fast Track group when compared to the control. CONCLUSION: The results of the study confirm that the application of the Fast Track protocol in orthopaedics after total knee replacement results in rapid post-surgery recovery. LEVEL OF EVIDENCE: IV. Case series, low-quality cohort or case-control studies.

Single and dual incision technique for acute distal biceps rupture: clinical and functional outcomes.

BACKGROUND: Distal bicep tendon injuries are a traumatic event though rather rare. The pathogenesis is not entirely clear. The most common cause for injury is an unexpected load on the biceps when the elbow is in an extended position. Although several studies have provided insight into the pathogenetic processes of the lesion, the literature suggests to treat all injuries surgically (whether partial or total) if there is high functional demand. METHODS: Between January 2006 and March 2016 were studied 20 patients surgically treated for a disconnected distal bicep, 15 with a total lesion and 5 with a partial lesion. The patients were divided into 2 groups. Surgical access with single incision was performed on 13 patients while a double surgical access was performed on 7 patients. The clinical and functional results were studied using an Ewald System Score (ESS). RESULTS: In both groups, the most rapid improvement was achieved for the parameters of pain and deformity with excellent results, while those of function and movement were normalized as gradual and progressive over next 2 months. CONCLUSION: The clinical and functional outcomes during the follow-up examination after surgery showed excellent results in patients treated with both types of surgical procedures.

New perspectives for articular cartilage repair treatment through tissue engineering: A contemporary review.

In this paper review we describe benefits and disadvantages of the established methods of cartilage regeneration that seem to have a better long-term effectiveness. We illustrated the anatomical aspect of the knee joint cartilage, the current state of cartilage tissue engineering, through mesenchymal stem cells and biomaterials, and in conclusion we provide a short overview on the rehabilitation after articular cartilage repair procedures. Adult articular cartilage has low capacity to repair itself, and thus even minor injuries may lead to progressive damage and osteoarthritic joint degeneration, resulting in significant pain and disability. Numerous efforts have been made to develop tissue-engineered grafts or patches to repair focal chondral and osteochondral defects, and to date several researchers aim to implement clinical application of cell-based therapies for cartilage repair. A literature review was conducted on PubMed, Scopus and Google Scholar using appropriate keywords, examining the current literature on the well-known tissue engineering methods for the treatment of knee osteoarthritis.

Advantages of exercise in rehabilitation, treatment and prevention of altered morphological features in knee osteoarthritis. A narrative review.

Knee osteoarthritis (OA) represents one of the most common causes of disability in the world. It leads to social, psychological and economic costs with financial consequences, also because a further increase is expected. Different knee OA treatments are usually considered in relation to the stage of the disease, such as surgical management and pharmacologic and non-pharmacologic treatments. Treatment should begin with the safest and least invasive one, before proceeding to more invasive, expensive ones. Non-pharmacologic, behavioral treatments of knee OA are recommended not only in rehabilitation but also in prevention because many risk factors, such as excess weight, obesity and joint tissue inflammation, can be monitored and thus prevented. In the present review, we analyze data from the most recent literature in relation to the effects of physical exercise on prevention, therapy and rehabilitation in knee OA. All data suggest that physical exercise is an effective, economical and accessible tool to everyone, in the treatment and prevention of knee OA. The literature search was conducted on PubMed, Scopus and Google Scholar using appropriate keywords in relation to knee osteoarthritis.
