Revision of the humeral component in shoulder arthroplasty is frequently necessary during revision surgery. Newer devices have been developed that allow for easy extraction or conversion at the time of revision preserving bone stock and simplifying the procedure. However, early generation anatomic and reverse humeral stems were frequently cemented into place. Monoblock or fixed collar stems make accessing the canal from above challenging. The cortex of the Humerus is far thinner than the femur and stress shielding has commonly led to osteopenia. Many stem designs have fins that project into the tuberosities putting them at risk for fracture on extraction. Extraction starts with an extended
We treated surgically 16 shoulders with an isolated traumatic rupture of the subscapularis tendon over a six-year period. Nine patients had a total and seven a partial tear of the subscapularis tendon. Repair was undertaken through a small
Purpose: The purpose of this multicentric study was to report results obtained with the Aequalis system using the simple humeral or total prosthesis, at at least two years follow-up in patients with shoulder joint degeneration and non-repairable rotator cuff tears. Material and methods: Sixty-eight Aequalis arthroplasties were performed between 1992 and 1998. Outcome was assessed on the basis of the Constant score and radiological findings. Female gender predominated (78%) in this series with a mean age of 72 years. There were 62 simple humeral implantations and six total shoulder arthroplasties. The
Metal and ceramic humeral head bearing surfaces are available choices in anatomical shoulder arthroplasties. Wear studies have shown superior performance of ceramic heads, however comparison of clinical outcomes according to bearing surface in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) is limited. This study aimed to compare the rates of revision and reoperation following metal and ceramic humeral head TSA and HA using data from the National Joint Registry (NJR), which collects data from England, Wales, Northern Ireland, Isle of Man and the States of Guernsey. NJR shoulder arthroplasty records were linked to Hospital Episode Statistics and the National Mortality Register. TSA and HA performed for osteoarthritis (OA) in patients with an intact rotator cuff were included. Metal and ceramic humeral head prostheses were matched within separate TSA and HA groups using propensity scores based on 12 and 11 characteristics, respectively. The primary outcome was time to first revision and the secondary outcome was non-revision reoperation.Aims
Methods
Anatomic and accurate placement of components is a primary goal in all arthroplasty procedures. Unique to total shoulder arthroplasty, challenging glenoid exposure and osteoarthritic glenoid deformity offer significant challenges and impediments to this goal. Despite thorough pre-operative planning strategies and contemporary cannulated pin-based shoulder systems, it is often times still difficult to accurately aim the guide pin to the medial border of the scapula when the deformity is substantial or exposure is difficult. Even small errors in guide pin position can result in problems with final component version, inclination and glenoid vault perforation. In addition, a malpositioned glenoid component has been shown to have a negative impact on implant longevity and clinical performance. Image-based patient specific instrumentation has been available in the lower extremity for nearly a decade with reliable results. The application of similar technology in the shoulder has demonstrated reliable positioning of the guide pin to a pre-operative plan with subsequent accurate placement of the glenoid component. This surgical demonstration will feature one of the currently available CT-based patient specific glenoid guides using a standard
The aim of this study is to evaluate the change in incidence rate of shoulder arthroplasty, indications, and surgeon volume trends associated with these procedures between January 2003 and April 2021 in the province of Nova Scotia, Canada. A total of 1,545 patients between 2005 and 2021 were analyzed. Patients operated on between 2003 and 2004 were excluded due to a lack of electronic records. Overall, 84.1% of the surgeries (n = 1,299) were performed by two fellowship-trained upper limb surgeons, with the remainder performed by one of the 14 orthopaedic surgeons working in the province.Aims

Aim. Recent studies have indicated that the presence of P. acnes in the skin of the shoulder and around the acromion is higher than other body regions like the knee or the hip. The aim of this study was to estimate the presence of P. acnes in a real set of primary shoulder arthroplasty, after skin preparation with chlorhexidine and administration of empirical antibiotic therapy. Method. A prospective observational study involving 63 patients undergoing primary shoulder arthroplasty was designed. In all patients two skin biopsies with a 3 mm dermal punch and one subcutaneous tissue sample after surgical incision were obtained. Skin biopsies were obtained at the most anterior part of the surgical wound in case of superior approach and at the upper part in the

Reverse total shoulder arthroplasty (rTSA) can be used in complex cases when the glenoid requires reconstruction. In this study, a baseplate with composite bone autograft and a central trabecular titanium peg was implanted, and its migration was assessed for two years postoperatively using radiostereometric analysis (RSA). A total of 14 patients who underwent a rTSA with an autograft consented to participate. Of these, 11 had a primary rTSA using humeral head autograft and three had a revision rTSA with autograft harvested from the iliac crest. The mean age of the patients was 66 years (39 to 81). Tantalum beads were implanted in the scapula around the glenoid. RSA imaging (stereographic radiographs) was undertaken immediately postoperatively and at three, six, 12, and 24 months. Analysis was completed using model-based RSA software. Outcomes were collected preoperatively and at two years postoperatively, including the Oxford Shoulder Score, the American Shoulder and Elbow Score, and a visual analogue score for pain. A Constant score was also obtained for the assessment of strength and range of motion.Aims

Vascular compromise due to arterial injury is a rare but serious complication of a proximal humeral fracture. The aims of this study were to report its incidence in a large urban population, and to identify clinical and radiological factors which are associated with this complication. We also evaluated the results of the use of our protocol for the management of these injuries. A total of 3,497 adult patients with a proximal humeral fracture were managed between January 2015 and December 2022 in a single tertiary trauma centre. Their mean age was 66.7 years (18 to 103) and 2,510 (72%) were female. We compared the demographic data, clinical features, and configuration of those whose fracture was complicated by vascular compromise with those of the remaining patients. The incidence of vascular compromise was calculated from national population data, and predictive factors for its occurrence were investigated using univariate analysis.Aims

This study aimed to assess the impact of using the metal-augmented glenoid baseplate (AGB) on improving clinical and radiological outcomes, as well as reducing complications, in patients with superior glenoid wear undergoing reverse shoulder arthroplasty (RSA). From January 2016 to June 2021, out of 235 patients who underwent primary RSA, 24 received a superior-AGB after off-axis reaming (Group A). Subsequently, we conducted propensity score matching in a 1:3 ratio, considering sex, age, follow-up duration, and glenoid wear (superior-inclination and retroversion), and selected 72 well-balanced matched patients who received a standard glenoid baseplate (STB) after eccentric reaming (Group B). Superior-inclination, retroversion, and lateral humeral offset (LHO) were measured to assess preoperative glenoid wear and postoperative correction, as well as to identify any complications. Clinical outcomes were measured at each outpatient visit before and after surgery.Aims

Introduction. The use of reverse total shoulder arthroplasty (RSA) is becoming increasingly common in the treatment of rotator cuff arthropathy. In recent years indications for use have expanded to include elderly patients in whom either internal fixation is not possible due to fracture configuration, poor bone quality, or presence of a rotator cuff deficiency. There is however relatively little evidence to support its use in these circumstances. Objective. This study aims to assess the viability of RSA as a salvage procedure in the treatment of complex proximal humeral fractures or irreducible dislocations, quantified in terms of functional outcome, complication rates and patient reported satisfaction. Methods. All patients presenting between January 2011 and December 2013 with a complex 3- or 4-part humeral fracture or a delayed presentation with an irreducible non-acute dislocation, treated with salvage RSA were eligible for inclusion. All operations were performed in a single centre by one of two specialist upper limb surgeons. Standard
The open Latarjet procedure is a widely used treatment for recurrent anterior instability of the shoulder. Although satisfactory outcomes are reported, factors which influence a patient’s experience are poorly quantified. The aim of this study was to evaluate the effect of a range of demographic factors and measures of the severity of instability on patient-reported outcome measures in patients who underwent an open Latarjet procedure at a minimum follow-up of two years. A total of 350 patients with anterior instability of the shoulder who underwent an open Latarjet procedure between 2005 and 2018 were reviewed prospectively, with the collection of demographic and psychosocial data, preoperative CT, and complications during follow-up of two years. The primary outcome measure was the Western Ontario Shoulder Instability Index (WOSI), assessed preoperatively, at two years postoperatively, and at mid-term follow-up at a mean of 50.6 months (SD 24.8) postoperatively. The secondary outcome measure was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. The influence of the demographic details of the patients, measurements of the severity of instability, and the complications of surgery were assessed in a multivariate analysis.Aims

Background. Total Shoulder Arthroplasty (TSA) has been shown to improve the function and pain of patients with severe degeneration. Recently, TSA has been of interest for younger patients with higher post-operative expectations; however, they are treated using traditional surgical approaches and techniques, which, although amenable to the elderly population, may not achieve acceptable results with this new demographic. Specifically, to achieve sufficient visualization, traditional TSA uses the highly invasive
Introduction. The use of reverse total shoulder arthroplasty (RSA) is becoming increasingly common in the treatment of rotator cuff arthropathy. Standard RSA technique involves medialising the centre of rotation (COR) maximising the deltoid lever arm and compensating for rotator cuff deficiency. However reported complications include scapular notching, prosthetic loosening and loss of shoulder contour. As a result the use of Bony Increased Offset Reverse Shoulder Arthroplasty (BIO-RSA) has been gaining in popularity. The BIO-RSA is reported to avoid these complications by lateralising the COR using a modified base plate, longer central post and augmentation with cancellous bone graft harvested from the patients humeral head. Objectives. This study aims to compare the outcome in terms of analgesic effect, function and satisfaction, in patients treated with standard RSA and BIO-RSA. Methods. All cases were performed in a single centre by one of two upper limb consultant orthopaedic surgeons over a consecutive 2-year period. At time of listing for operation, the decision as to whether to undertake a bony-increased offset reverse total shoulder was made. Standard
Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford Shoulder Score (OSS), and EuroQol five-dimension three-level questionnaire (EQ-5D-3L) were recorded preoperatively and postoperatively.Aims

Purpose. While reverse shoulder arthroplasty (RSA) corrects vertical muscle imbalance, it cannot restore the horizontal imbalance seen in cuff-deficient shoulders with combined loss of active elevation and external rotation (CLEER). We report the medium-term results of the modified latissimus dorsi/teres major tendon transfer (L'Episcopo procedure) associated with RSA, performed via a single
This study reviews the use of intramedullary fibular allograft in treating nonunion of the humeral neck in 11 patients. Nine women and two men with a mean age of 76 years (63 to 89) were followed up for a mean of 61 months (14 to 72). The nonunion was exposed through a
Purpose of the study: Proximal fractures of the humerus account for 10% of fractures in persons aged over 65 years. There is no optimal treatment. The goal of surgery is to restore joint congruency, preserve vascular supply, and allow functional recovery. We describe the results obtained with a surgical technique designed to meet these goals. Material and methods: Fifteen 3-fragment fractures of the proximal humerus were treated with transosseous suture. Mean age of patients was 58 years. Eighty-six percent of the patients were female. Follow-up was 18 months on average. The patients were placed in a lounge chair position for the
Introduction: Surgical treatment of most displaced proximal humerus fractures is challenging due to osteoporosis, which makes stable fixation difficult. Locking plates are intended to provide superior mechanical stability. The NCB. ®. -PH (Non-Contact-Bridging for the Proximal Humerus) plate is a locking plate of the latest generation that allows both open and minimally invasive (MI) application. Methods: In a prospective multicenter study 131 patients were treated (n = 78 open, n = 53 MI). The open procedure was performed using a standard
Introduction:. The subscapularis muscle experiences significant strain as it accommodates common movements of the shoulder. Little is known about what happens with this obligatory strain once the subscapularis insertion is disrupted and repaired in the course of shoulder arthroplasty. Subscapularis failure is a serious known complication after shoulder arthroplasty. It is not known what the effect of increasing the thickness of the shoulder head will have on subscapularis strain. It is our hypothesis that the use of large or expanded humeral heads during shoulder replacement will cause increased tension in the repaired subscapularis. The primary purpose of this study was to identify the optimal manner to perform a passive range of motion (PROM) program without invoking a significant increase in strain in the repaired subscapularis. The secondary purpose was to determine the impact of varying the thickness of the humeral head on subscapularis strain using the same PROM protocol. Methods:. Eight fresh-frozen, forequarter cadaver (four female, four male) specimens were obtained following IRB approval. An extended
The aim of this study was to report the incidence of implant-related complications, further operations, and their influence on the outcome in a series of patients who underwent primary reverse total shoulder arthroplasty (RTSA). The prospectively collected clinical and radiological data of 797 patients who underwent 854 primary RTSAs between January 2005 and August 2018 were analyzed. The hypothesis was that the presence of complications would adversely affect the outcome. Further procedures were defined as all necessary operations, including reoperations without change of components, and partial or total revisions. The clinical outcome was evaluated using the absolute and relative Constant Scores (aCS, rCS), the Subjective Shoulder Value (SSV) scores, range of motion, and pain.Aims

Aims: The purpose of this study was to evaluate the efficacy of the inverted Delta 3 prosthesis in nonreconstructable massive rotator cuff tear. Methods: 31 inverted Delta 3 prostheses were performed between October 1999 and February 2002. The average age was 72.8 years old (65–84) and the average follow-up was 17.8 months (3–36). A
The purpose of this study was to look at the results of using the Copeland surface replacement in the treatment of arthritis of the shoulder.

Primary synovial chondromatosis, defined by Jaffe (1951), is a rare, benign arthropathy, of unknown aetiology, distinguished by the chondroid metaplasia of the synovial membrane of the joint, bursa or tendon sheath, which leads to the formation of loose bodies, usually intra-articular. It is characteristically monoarticular and the knee, hip and elbow are the joints most commonly affected. The shoulder is a rare localisation and the extra-articular involvement even rarer, with only few cases presented in the literature. The diagnosis is possibilited by the clinical examination and by the confirmation of the presence of multiple intra-articular loose bodies by roentgenographic studies and magnetic resonance (MR). The treatment is always surgical. Malignant degeneration of synovial chondromatosis into chondrosarcoma is described, although rare. We report an exceptionally rare case of synovial osteochondromatosis of the shoulder with combined intra and extra-articular involvement in a 28 years old female patient, former athlete. She presented with a five-year history of shoulder pain and slight limitation of motion. Radiographic examination and magnetic resonance imaging led us to the diagnosis of synovial chondromatosis of the shoulder. The patient underwent arthroscopic removal of the intra-articular loose bodies and partial synovectomy. The subscapularis recess was then identified through an anterior
Purpose of the study: The purpose of this study was to determine the feasibility and reproducibility of a new arthroscopic procedure combining a Bristow-Latarjet lock with Bankart reinsertion of the lambrum. Material and methods: Forty-seven consecutive patients with significant bone defects in the glenoid and a deficient capsule were treated arthroscopically: arthroscopic Bankart had failed in six. The procedure was performed exclusively arthroscopically using a special instrumentation: after its osteotomy and identification of the axiallary nerve, the coracoids was passed through the subcapular muscle with its tendon; the block was fixed on the scapular neck after 90° lateral rotation so as to prolong the natural concavity of the glenoid. Anchors and sutures were then used to refix the capsule and the labrum onto the glenoid border, leaving the block in an extra-articular position. Follow-up included a physical examination and standard x-rays at 45, 90 and 180 days; 31 patients had a postoperative scan. Three independent operators read the images. Results: The procedure was completed arthroscopically in 41 of 47 patients (8%); conversion to a
Our aim was to analyse radiological outcome of proximal humerus fractures treated with Philos plate and to assess its usefulness in treatment of malunion and non-union. Seventy-seven patients were treated with Philos plate (24 men and 53 women). Mean age was 61 years (15–88). There were 66 acute fractures, 6 nonunion, 4 mal-union and one periprosthetic fracture. Acute fractures included 29 two part, 30 three part and five 4 part fractures. Seven had associated dislocation. There were two head splitting fractures.
Background. In elderly patients with complex proximal humerus fractures and osteoporotic bone reconstruction is not always possible. Although hemiarthroplasty is an alternative, non-union or tuberosity migration can lead to inferior functional results. Implantation of a Reverse Total Shoulder Arthroplasty (RTSA) seems to be an interesting alternative. In the present study we retrospectively analyzed the short-term results of RTSA for complex proximal humerus fractures in the elderly. Methods. From 31.10.2005 to 20.07.2010 RTSA was performed in 29 patients (average age 80 years [67;90], 25 women, 4 man) with subcapital, three- or four-part fracture of the proximal humerus as a primary treatment. All procedures were performed using the Anatomical Inverse Shoulder (Zimmer) with fracture stem. A
In 42 elderly patients, 33 women and nine men with a mean age of 72 years, we treated displaced fractures of the proximal humerus (34 three-part, 8 four-part) using a blade plate and a standard
The axillary nerve injuries most commonly are observed after trauma such as contusion-stretch, gunshot wound, laceration and iatrogenic injuries. Two of the most commons causes seem to be the glenohumeral dislocation and the proximal humerus fractures. The axillary nerve may sustain a simple contusion, or its terminal elements may be avulsed from the deltoid muscle. Compressive neuropathy in the quadrilateral space also has been reported (quadrilateral space syndrome, Calhill and Palmer, 1983). The axillary nerve injuries incidence represents less than 1% of all nerve injuries. Aim: The purpose of this study was to analyze outcome in patients, who presented with injuries to the axillary nerve. Material and methods: We report a series of 15 cases of axillary nerve lesions, which were operated between 1995 and 2002. These injuries resulted from shoulder injury either with or without fracture and or dislocation. Patients were operated between 3 to 6 months after trauma and an anterior
Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes. In this prospective cohort study, radiostereometric analysis (RSA) radiographs were obtained in 24 patients at one day, six weeks, six months, one year, and two years postoperatively. Migration was calculated using model-based RSA. Clinical outcomes were evaluated using the visual analogue scale (VAS), the Oxford Shoulder Score (OSS), the Constant-Murley Score (CMS), and the Disabilities of the Arm, Shoulder and Hand (DASH) score.Aims

Scapular notching is of concern in reverse shoulder arthroplasty and has been suggested as a cause of glenoid loosening. Our purpose was to analyze in a large series the characteristics and the consequences of the notch and then to enlighten the causes in order to seek some solutions to avoid it. 430 consecutive patients (457 shoulders) were treated by a reverse prosthesis for various etiologies between 1991 and 2003 and analyzed for this retrospective multicenter study. Adequate evaluation of the notch was available in 337 shoulders with a follow-up of 47 months (range, 24–120 months). The notch has been diagnosed in 62% cases at the last follow-up. Intermediate reviews show that the notch is already visible within the first postoperative year in 82% of these cases. Frequency and grade extension of the notch increase significantly with follow-up (p<
0.0001) but notch, when present, is not always evolutive. At this point of follow-up, scapular notch is not correlated with clinical outcome. There is a correlation with humeral radiolucent lines, particularly in metaphyseal zones (p=0.005) and with glenoid radiolucent lines around the fixation screws (p=0.006). Significant preoperative factors are: cuff tear arthropathy (p=0.0004), muscular fatty infiltration of infraspinatus (p=0.01), narrowing of acromio-humeral distance (p<
0.0001) and superior erosion of the glenoid (p=0.006). It was more frequent with superolateral approach than with
Introduction. Persistent problems and relatively high complication rates with reverse total shoulder arthroplasty (RTSA) are reported (1, 2). It is assumed that some of these complications are affected by improper intraoperative soft tissue tension. Achieving proper intraoperative soft tissue tension is an obvious surgical goal. However, intraoperative soft tissue tension measurements and methods for RTSA have not been reported. One way to quantify soft tissue tension is to measure intraoperative joint forces using an instrumented prosthesis. Hence, we have developed an instrumented RTSA to measure shoulder joint forces intraoperatively. The goal of this study was to measure intraoperative shoulder joint forces during RTSA. Materials and Methods. The instrumented shoulder prosthesis measures the contact force vector between the glenosphere and humeral tray. This force sensor is a custom instrumented trial implant that can be used with an existing RTSA system (EQUINOXE, Exactech Inc, Gainesville, FL) just as a standard trial implant is used. Four uniaxial foil strain gauges (QFLG-02-11-3LJB, Tokyo Sokki Kenkyujo Co., Ltd., JP) are instrumented inside the sensor. Using a calibration matrix, the three force components were calculated from four strain gauge outputs (3). Sixteen patients who underwent RTSA took part in this IRB approved study. All patients were greater than 50 years of age and willing to review and sign the study informed consent form. After obtaining informed consent for surgery, a standard
The use and variety of stemless humeral components in anatomical total shoulder arthroplasty (TSA) have proliferated since their advent in 2004. Early outcomes are reassuring but independent mid-term results are scarce. This independent study reports a consecutive series of 143 Eclipse stemless shoulder prostheses with a minimum five-year (5 to 10) follow-up. Outcomes of 143 procedures undertaken for all indications in 131 patients were reviewed, with subset analysis of those for osteoarthritis (OA) (n = 99). The primary outcome was the Oxford Shoulder Score (OSS) at a minimum of five years. Secondary outcomes were ranges of motion and radiological analysis of humeral radiolucency, rotator cuff failure, and glenoid loosening.Aims

Purpose: To audit the improvement in function gained in patients with cuff tear arthropathy (CTA) using the reversed geometry delta 3 prosthesis and to balance this against operative and postoperative complications encountered. Method: 20 consecutive patients with CTA were assessed using the ASES and Constant scores pre and postoperatively. Results: All patients reported a marked improvement in post-operative pain relief. Average elevation increased from 49° to 102°. Function improved significantly. On the downside this is a technically difficult procedure in a group of patients whose average age was 81 (73–91) but whose biological age was higher. Technical difficulties arise from access to the glenoid, in particular to the inferior margin of the glenoid through a deltoid splitting approach. For this reason the surgical approach was changed to an extended
Introduction: Various surgical techniques existed for the treatment of three and four part proximal humeral fractures with variable outcomes. The aim of this study is to present a technique using small materials, to preserve all the biologic principles of fracture fixation, in the treatment of these challenging injuries. Material: We perform a study taking as inclusion criteria: 3 and 4 parts proximal, closed, humeral fractures, treated surgically by open reduction and a modular biological internal fixation. Surgical technique: Through a standard
The Copeland Shoulder Arthroplasty is a cementless, pegged humeral head surface replacement. The design is based on the principle of minimal bone resection and has been in clinical use since 1986. The only published series to date, that of Levy and Copeland, reported results for 103 patients which were comparable to those obtained with stemmed implants. We report the outcome at our institution using the same prosthesis with a hydroxyapatite coating. 81 shoulders (74 patients) underwent resurfacing hemiarthroplasty through an anterior
Background: Avascular necrosis is a well recognised complication of displaced proximal humeral fractures irrespective of conservative and operative treatment. The reported rate of AVN with open reduction and internal fixation varies from 22 to 40%. The aim of our study was to look at the functional outcome and the incidence of AVN with operative treatment using locking plate with a minimum 3 year follow up. Materials and methods: We retrospectively reviewed a consecutive series of 50 patients with displaced proximal humerus fractures treated with ORIF from 2002 to 2004. All patients were operated by the two senior authors employing anterior
The benefit of open stabilization for recurrent shoulder instability is well known, however there have been recent reports of postoperative dysfunction of the subscapularis tendon following open shoulder surgery (Habermeyer et al, Scheibel et al). We present our findings in patients who have undergone an open anterior stabilization using a subscapularis split approach. We reviewed 48 patients (49 shoulders), who were treated by the senior author (SB) from 2003–2005. They all underwent an open anterior stabilization of shoulder through a
A 18-year-old woman patient suffering from JCA was operated on non-dominant left shoulder joint destruction. The dysplasia of the affected side was clearly recognisable on the X-ray befor the operation as compared to the other side. The smallest of the prothesis typs (De Puy Global, Biomet Modular) couldn’t be implanted. So we have used an other method. We have achived good results for years by using Tuto-plast‚ Dura mater (Tutogen Medical GmbH) in operating interposition elbow arthtroplasty of RA patients. This was the basic idea in this case to apply shouldes joint interposition arthroplasty. There have been previous publications on other interposition tecniques. Operations technique:. Traditionally we approached the shoulder in
Patients using a neutral rotation brace post proximal humerus fracture fixation have improved functional outcome and external rotation of the shoulder compared to patients using a standard polysling. Patients who have proximal humerus fracture fixation with extramedullary plates and screws have a risk of reduced range of movement especially external rotation. Gerber et al showed that the average external rotation after fixation of proximal humeral fractures was 39 degrees in their patient cohort compared to a normal range of 80–100 degrees. This can lead to reduced function and poor patient related outcomes. Geiger et al showed that in a cohort of 28 patients, poor functional outcome was noted in 39.3% with an average Constant-Murley Score of 57.9. Current practice is to utilise a polysling holding the shoulder in internal rotation post-shoulder fixation. Patients usually wear the sling for up to 6 weeks. We believe that this increases the risk of adhesion formation with the shoulder in internal rotation in the shoulder joint. Therefore this can cause loss of external rotation in the shoulder joint. We believe that holding the shoulder in a neutral alignment, with a neutral rotation brace post-fixation, will enable an increased rate of external rotation post-operatively thus improving external rotation and functional outcome. There is currently no literature comparing the different slings used post-operatively and we believe that this study would be the first of its kind. It would have a substantial change in the way clinicians manage proximal humeral fractures and will potentially reduce the numbers of re-operations to divide adhesions or perform capsular releases. Secondary benefits include a potential earlier return to full function and work and improved patient satisfaction. Study proposal: Prospective Randomised Controlled Trial of the neutral rotation brace compared to the standard, currently used, polysling post proximal humerus fracture fixation. No blinding of either participants or clinicians. Three surgeons utilising similar fixation techniques via the
Background: The Bankart repair remains a safe and effective method for repairing instability in shoulder injuries. We report the results of a large series of patients treated using this technique. Materials and Methods: We retrospectively reviewed 136 consecutively treated patients with either anterior, antero-inferior or multidirectional shoulder instability over a 7-year period from 1999–2006 with a minimum of 2-year follow-up. All patients underwent open bankart repair through a
Aim: To evaluate the results of internal fixation of displaced proximal humeral fractures with a locking plate system. Material and Methods: Between 2002 and 2003, 126 patients presented to our shoulder unit with proximal humeral fractures. Of these, 22 healthy active patients with displaced two to four-part fractures underwent open reduction and internal fixation with a locking compression plate system (Philos, Stratec UK Ltd). Their average age was sixty-two years. They were evaluated clinically and radiologically at 4, 12, 26 weeks or until union. Objective assessment was measured by the Constant scoring system, subjective assessment by the Oxford shoulder questionnaire. Surgical Technique: Through an anterior
Purpose of the study: The reversed total shoulder prosthesis is one of the treatments currently proposed for excentered glenoid osteoarthritic degeneration with massive rotator cuff tears. In light of the mediocre or at best highly variable results obtained with osteosynthesis or humeral arthroplasty for four-fragment fractures of the proximal humerus, indications for the reversed total shoulder prosthesis have been widened to include this category of traumatology patients. The purpose of this prospective study was to report outcome with the reversed prosthesis used for complex fracture of the proximal humerus in subjects aged over 70 years. Material and methods: Ten patients, mean age 76 years, underwent surgery performed by the same surgeon to insert a Delta (DePuy) reversed prosthesis for four-fragment complex displaced fracture of the proximal humerus. The
Introduction: The reverse shoulder arthroplasty (RSA) is becoming increasingly common and the indications expanded. The objective of this study is to report the indications and results of RSA in a large multicenter study. Methodology: A retrospective, multicenter study was conducted including all RSA implanted between 1992 and 2002 in five centers in France. Of 457 patients involved in this study, 243 patients (53%) had cuff pathology: 149 had cuff tear arthropathy, 48 had massive cuff tears, and 45 had failed cuff surgery. Ninety-nine (22%) had revision of previous prostheses. Sixty (13%) had fracture-related problems. Twenty-six (6%) had osteoarthritis and two percent each had rheumatoid arthritis, tumors or other conditions. Three hundred and eighty-nine (85%) shoulders were available for review with greater than 2 years follow-up. The average age at review was 75.6 years (range, 22–92). The average follow-up was 43.5 months (range, 24–142). Results: Significant improvement was noted in Constant scores for pain (3.5 to 12.1), activity (5.8 to 15.1), mobility (12.1 to 24.5), and strength (1.3 to 6.1) (p<
.0001). Active elevation improved, but active internal and external rotation did not. The results were dependent on the indication. Cuff tear arthropathy had the best results while revision procedures had the worst. Young age, preoperative stiffness, teres minor deficiency, tuberosity non-union and preoperative complaints of pain rather than loss of function tended to be associated with inferior results. The
Purpose: This paper will present the types and rates of complications of an initial consecutive series of 100 reverse total shoulder arthroplasties (TSA).

Purpose: Reverse shoulder arthroplasty (RSA) is becoming increasingly common for a variety of indications. The most common postoperative complication is instability. The objectives of this study are to describe causes of RSA instability and preventive and treatment recommendations. Method: All members of the American Shoulder and Elbow Society were asked for cases of RSA instability. We retrospectively reviewed 52 cases in 52 patients, performed by 13 surgeons. The mean age was 67.5 years (range, 36–83). The mean follow-up was 32.7 months (range, 3–43). Results: The etiology included: cuff tear arthropathy (14 patients); revision arthroplasty (13 patients); fracture sequelae (6 patients); and other (6 patients). Twenty-four patients had previous shoulder surgery. All patients had a
Introduction and Aims: Isolated rupture of the subscapularis tendon is an uncommon condition that has generally been treated by early surgical repair. However, very little information is available regarding functional outcome following surgery. The purpose of this study was to evaluate patient reported outcome following surgical repair with a minimum follow-up of 12 months. Method: Thirteen consecutive patients underwent arthroscopy followed by open surgical repair of an isolated traumatic rupture of the subscapularis tendon. A
Introduction: The treatment of Complex Proximal Humeral Fractures and Fractures associated with Dislocation is not still resolved. Internal Fixation sometimes is not possible due to comminuted and osteoporotic bone which is commonly found in this kind of Fractures. The use of Hemiarthroplasty in this situation, not always achieves a good functional outcome, usually related to a Non Union or Malunion of the Tuberosities. We began using Reversed Shoulder Arthroplasty in this Fractures due to good results this implant had had in Glenohumeral Arthritis associated a Rotator Cuff Deficiency. Material and Methods: From January 2004 to December 2008 we have treated 50 patients with Complex Proximal Humeral Fractures with a Reversed Shoulder Arthroplasty,38 were women and 12 were men with a mean age of 76 (38–84). The mean follow-up time was 20 months (10–36). We have used a Lima Reversed Arthroplasty in all the cases. The dominant arm were involved in 65 % of the patients. The
Humeral shaft fractures are among the most frequent fractures encountered in Orthopaedic Traumatology. Their treatment can be either conservative or operative depending on the location (proximal, middle or distal third), type (spiral, oblique, or transverse), radial nerve involvement, concomitant presence of thoracic injuries that preclude general anesthesia, as well as surgeon’s experience. Non union or delayed union complicates some of the conservatively and very few of the operatively treated fractures. We report of our experience with the management of humeral shaft non unions in 28 patients treated at our institution from 1990 to 2000. Six were male and twelve female aging from 21 to 68 years (mean 45 years).The interval between initial injury and operation varied from 6 months to 3 years (average 10 months).Regarding the location of non union,20 cases were located in the middle, 6 cases in the upper and 2 cases in the distal third. Operative technique: under general anesthesia using anterolateral approach for middle and distal third and
Purpose: The glenoid labrum is a significant passive stabiliser of the shoulder joint. However, its microstructural form remains largely unappreciated, particularly in the context of function. An understanding of the labral structure leads to mechanical hypotheses, and therefore functional role in stability and load distribution, will aid an educated approach to surgical timing and repair. Method: Fresh frozen cadaveric shoulders were grossly harvested via an extended
Aims: The revision of hemi or total arthroplasty represents a difficult challenge for a shoulder surgeon. The purpose of this study was to report the results of a retrospective series of 30 reverse prosthesis. Materials and Methods: 17 patients were female, 13 were male; the mean age was 68 (45–84). 14 patients had at least 2 surgeries before the arthroplasty. Of the failed arthroplasties, 26 were hemiarthroplasties and 4 were total shoulder arthroplasties. The indication for the revision of hemiarthroplasty were: 10 migration of the tuberosities, 7 secondary rotator cuff tears, 5 were stiff, 2 glenoiditis,, one humeral loosening and one sepsis. The indication for the revision of total arthroplasty were 3 loosenning of the glenoïd component and 2 secondary rotator cuff tear with a superior ascension of the humeral head. The rotator cuff was always irreparable. We used mainly a
The aim of this study was to assess the medium-term results of the Copeland cementless surface replacement of the shoulder for rheumatoid arthritis. Between 1986 and 1998, 75 patients with rheumatoid arthritis had a cementless surface replacement. They were 58 females and 17 males with a mean age 60 years (range: 24 to 88 years). The mean follow-up was 6 years (range: 2 to 14 years). The functional outcome was assessed using the Constant score and a patient satisfaction scale. The mean Constant score was 53.4 points for total shoulder replacements (76 age/ sex adjusted) and 47.9 points for hemiarthroplasty (71 age/ sex adjusted). Forward elevation improved from 50 degrees to 104 degrees for total shoulder replacements and from 47 degrees to 101 degrees for hemiarthroplasty. Seventytwo patients (96%) considered the shoulder to be better or much better. 3 patients (4%) felt the shoulder was the same. The
Introduction: Tumors of the axilla impose a surgical difficulty because they are usually large at presentation and in close proximity to the major neurovascular bundle of the upper extremity. Attempted tumor resection via the base of the axilla is difficult because of limited exposure of the axillary content and neurovascular bundle. The authors have used a safe and reliable exposure for these situations. Methods: Between 1980 and 1997, 35 patients underwent extensile exposure of an axillary tumor. Diagnoses included 19 primary and 16 metastatic tumors of the axilla. The axillary cavity was fully exposed via the
Purpose: Nonunion of the surgical neck of the humerus can occur after orthopaedic or poorly-adapted surgery after displaced subtuberosity or cephalotuberosity fracture. The purpose of this study was to report functional and radiographic outcome after treatment with shoulder prosthesis. Material and methods: Twenty-two patients who had a non-constrained shoulder prosthesis were included in this retrospective multicentric study. Mean age was 70 years and mean follow-up was 45 months (range 2 – 9 years). The initial fracture had two fragments in six patients and was a three-fragment fracture involving the head and the tubercle in thirteen and a four-fragment fracture in three. Orthopaedic treatment was given in ten cases and surgical osteosynthesis was used in twelve. Time from fracture to implant insertion was 20 months. The
Reverse total shoulder arthroplasty (RTSA) using trabecular metal (TM)-backed glenoid implants has been introduced with the aim to increase implant survival. Only short-term reports on the outcomes of TM-RTSA have been published to date. We aim to present the seven-year survival of TM-backed glenoid implants along with minimum five-year clinical and radiological outcomes. All consecutive elective RTSAs performed at a single centre between November 2008 and October 2014 were reviewed. Patients who had primary TM-RTSA for rotator cuff arthropathy and osteoarthritis with deficient cuff were included. A total of 190 shoulders in 168 patients (41 male, 127 female) were identified for inclusion at a mean of 7.27 years (SD 1.4) from surgery. The primary outcome was survival of the implant with all-cause revision and aseptic glenoid loosening as endpoints. Secondary outcomes were clinical, radiological, and patient-related outcomes with a five-year minimum follow-up.Aims
Methods
To report early (two-year) postoperative findings from a randomized controlled trial (RCT) investigating disease-specific quality of life (QOL), clinical, patient-reported, and radiological outcomes in patients undergoing a total shoulder arthroplasty (TSA) with a second-generation uncemented trabecular metal (TM) glenoid versus a cemented polyethylene glenoid (POLY) component. Five fellowship-trained surgeons from three centres participated. Patients aged between 18 and 79 years with a primary diagnosis of glenohumeral osteoarthritis were screened for eligibility. Patients were randomized intraoperatively to either a TM or POLY glenoid component. Study intervals were: baseline, six weeks, six-, 12-, and 24 months postoperatively. The primary outcome was the Western Ontario Osteoarthritis Shoulder QOL score. Radiological images were reviewed for metal debris. Mixed effects repeated measures analysis of variance for within and between group comparisons were performed.Aims

Purpose: We report the satisfactory results obtained in a retrospecive multicentric series of 80 shoulder prostheses implanted for aseptic osetonecrosis of the head of the humerus. Material and methods: Seventy-four patients (43 men, 31 women, men age 59 years) with aseptic osteonecrosis of the head of the humerus treated with a shoulder prosthesis were reviewed at least two years after surgery. The mean weighted score before surgery was 37%. Twenty-six total prostheses and 54 humeral prostheses were implanted via the
To devise an operative approach to the management of acute posterior fracture-dislocation of the shoulder which restores or retains normal proximal humeral anatomy and allows the early restoration of a complete, stable range of motion. Since 1996 we have treated four male patients (five shoulders) aged between 19 and 54 years at the time of first dislocation with autogenous iliac grafting of the anterior humeral head defect for acute and acuteon-chronic posterior dislocation of the shoulder. Two patients had epilepsy: one of these patients had bilateral dislocations. Two patients had motorbike RTAs. The
Primary synovial chondromatosis (PSC) is a rare benign disorder characterised by development of foci of cartilage in the synovial membrane of the joint, bursa or tendon sheath that was first described by Reichel in 1900. The disorder has traditionally been considered as a metaplastic condition, but was recently assoicated with structural chromosomal abnormalities, suggesting a neoplastic origin. The aim of the present study was to evaluate the clinical, arthroscopic and histopathological aspects of PSC involving both the glenohumeral joint and tendon sheath of the biceps. An 18-year-old, right-hand dominant boy presented with right shoulder pain. There was no history of trauma. Pain began in his shoulder about 1 year prior to his clinical visit. Physical examination revealed an active range of motion of the affected side measuring 90 ° of abduction and 150° of forward flexion; internal rotation to the greater trochanter of the hip and external rotation were slightly limited. Plain radiographs revealed multiple calcific nodules in the right glenohumeral joint, the subcoracoid recess, and anterior to the humeral head. There appeared to be mild degenerative changes in the gleno-humeral joint. Magnetic resonance imaging was performed to assess the location of the loose bodies and evaluate intra-articular degenerative changes. It demonstrated multiple loose bodies within the glenohumeral joint, the proximal tendon sheath of the biceps, and also in the subscapularis bursa. There was irregularity involving the anterior aspect of the humeral head consistent with erosive changes. The patient underwent arthroscopic surgery to remove the loose bodies, arthroscopic partial synovectomy and decompression of the biceps tendon sheath, with removal of multiple loose bodies. For partial synovectomy a motorized suction-cutting device alternated between anterior and posterior portals. The biceps tendon was identified through an anterior
The purpose of this study was to compare clinical results, long-term survival, and complication rates of stemless shoulder prosthesis with stemmed anatomical shoulder prostheses for treatment of osteoarthritis and to analyze radiological bone changes around the implants during follow-up. A total of 161 patients treated with either a stemmed or a stemless shoulder arthroplasty for primary osteoarthritis of the shoulder were evaluated with a mean follow-up of 118 months (102 to 158). The Constant score (CS), the Disabilities of the Arm, Shoulder and Hand (DASH) score, and active range of motion (ROM) were recorded. Radiological analysis for bone adaptations was performed by plain radiographs. A Kaplan-Meier survivorship analysis was calculated and complications were noted.Aims
Methods
The purpose of this study was to report bone adaptive changes after anatomical total shoulder arthroplasty (TSA) using a standard-length hydroxyapatite (HA)-coated humeral component, and to report on a computer-based analysis of radiographs to determine changes in peri-implant bone density objectively. A total of 44 TSAs, performed between 2011 and 2014 using a cementless standard-length humeral component proximally coated with HA, were included. There were 23 males and 21 females with a mean age of 65 years (17 to 65). All shoulders had good quality radiographs at six weeks and five years postoperatively. Three observers graded bone adaptive changes. All radiographs were uploaded into a commercially available photographic software program. The grey value density of humeral radiological areas was corrected to the grey value density of the humeral component and compared over time.Aims

Materials and methods: From 1993 to 2001 in 20 patients with rheumatoid arthritis 24 total shoulder arthroplasties were performed. Concerning 19 Biomet total shoulder arthroplasties of which one glenoid component and one humeral component were cemented for optimal fixation. Five Aequalis total shoulder arthroplasties were performed, one with an uncemented glenoid component. The pre-operative diagnosis was rheumatoid arthritis in the whole Biomet-group. In the Aequalis-group there were four patients with rheumatoid arthritis and one patient with juvenile chronic arthritis. The mean age was 48 (19–76) years. The mean pre-operative range of motion was flexion 80 (40–150), external rotation 23 (–20 – 65) and abduction 55 (0–110) degrees. Pre-operative shoulder X-rays were staged according to Larssen. In the Biomet-group this resulted in eight times Larssen 3, nine times Larssen 4 and two times Larssen 5; in the Aequalis-group five times Larssen 4. All 24 operations were performed by a
Purpose: Fractures of the upper humerus are frequent in elderly persons. While 80% are generally treated orthopaedically, about 20% are complex complicating treatment. Osteosythesis has given disappointing results due to the poor bone quality. Simple humeral arthroplsaty with simple tuberosity fixation could be a solution. Material and method: Between 1993 and 1998, 50 patients, 39 women and 11 men, mean age 74.5 years (51–90) were treated for cephalotuberosity fractures with cemented humeral arthroplasty. The dominant side was involved in 80% of the cases; there were 39 fractures with four fragments in the Neer classification with seven associated with anterior dislocation, eleven with three fragments including two associated with anterior dislocation. Three patients had a neurological complication: elongation of the brachial plexus in one and irritation of the ulnar nerve in two. Mean delay to surgery was 2.4 days. Thirty-seven patients were operated via the superolateral approach, 13 via the
Existing literature indicates that inferiorly inclined glenoid baseplates following reverse total shoulder arthroplasty (RSA) produce better outcomes compared to superiorly inclined baseplates. We aim to compare clinical outcomes for RSAs with superiorly and neutrally/inferiorly inclined lateralized glenospheres. We retrospectively reviewed 154 consecutive patients undergoing RSA between July 2015 and July 2017 by one single-fellowship trained surgeon (AJ). Two raters (KAM and MVS) independently measured glenoid inclination in preoperative and minimum two year follow-up radiographs (anteroposterior/Grashey) using the RSA angle. Inclination was then compared to patient-reported outcomes, range of motion (ROM), and independently assessed degree of scapular notching and staging of heterotopic ossification at two year follow-up.Aims

The Mathys Affinis Short is the most frequently used stemless total shoulder prosthesis in the UK. The purpose of this prospective cohort study is to report the survivorship, clinical, and radiological outcomes of the first independent series of the Affinis Short prosthesis. From January 2011 to January 2019, a total of 141 Affinis Short prostheses were implanted in 127 patients by a single surgeon. Mean age at time of surgery was 68 (44 to 89). Minimum one year and maximum eight year follow-up (mean 3.7 years) was analyzed using the Oxford Shoulder Score (OSS) at latest follow-up. Kaplan-Meier survivorship analysis was performed with implant revision as the endpoint. Most recently performed radiographs were reviewed for component radiolucent lines (RLLs) and proximal humeral migration.Aims

The aim of this study was to explore why some calcar screws are malpositioned when a proximal humeral fracture is treated by internal fixation with a locking plate, and to identify risk factors for this phenomenon. Some suggestions can be made of ways to avoid this error. We retrospectively identified all proximal humeral fractures treated in our institution between October 2016 and October 2018 using the hospital information system. The patients’ medical and radiological data were collected, and we divided potential risk factors into two groups: preoperative factors and intraoperative factors. Preoperative factors included age, sex, height, weight, body mass index, proximal humeral bone mineral density, type of fracture, the condition of the medial hinge, and medial metaphyseal head extension. Intraoperative factors included the grade of surgeon, neck-shaft angle after reduction, humeral head height, restoration of medial support, and quality of reduction. Adjusted binary logistic regression and multivariate logistic regression models were used to identify pre- and intraoperative risk factors. Area under the curve (AUC) analysis was used to evaluate the discriminative ability of the multivariable model.Aims

The purpose of this study was to determine whether there were long-term differences in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years. This was a prospective cohort study comparing 67 patients with acute complex proximal humeral fracture and 64 patients with irreparable rotator cuff deficiency who underwent primary RSA. In the fracture group, there were 52 (77.6%) females and 15 (22.4%) males, with a mean age of 73.5 years (51 to 85), while in the arthropathy group, there were 43 (67.1%) females and 21 (32.9%) males, with a mean age of 70.6 years (50 to 84). Patients were assessed by the Constant score, University of California Los Angeles shoulder score (UCLA), short version of the Disability of the Arm Shoulder and Hand score (QuickDASH), and visual analogue scales (VAS) for pain and satisfaction. Radiological evaluation was also performed.Aims

Heterotopic ossification (HO) is a potentially devastating complication of the surgical treatment of a proximal humeral fracture. The literature on the rate and risk factors for the development of HO under these circumstances is lacking. The aim of this study was to determine the incidence and risk factors for the development of HO in these patients. A retrospective analysis of 170 patients who underwent operative treatment for a proximal humeral fracture between 2005 and 2016, in a single institution, was undertaken. The mean follow-up was 18.2 months (1.5 to 140). The presence of HO was identified on follow-up radiographs.Aims

Reverse shoulder arthroplasty (RSA) reliably improves shoulder pain and function for a variety of indications. However, the safety and efficacy of RSA in elderly patients is largely unknown. The purpose of this study was to report the mortality, morbidity, complications, reoperations, and outcomes of primary RSA in patients aged > 80 years. Between 2004 and 2013, 242 consecutive primary RSAs were performed in patients aged > 80 years (mean 83.3 years (Aims
Patients and Methods
A number of methods have been described to remove a well-fixed humeral implant as part of revision shoulder arthroplasty. These include the use of cortical windows and humeral osteotomies. The router bit extraction technique uses a high-speed router bit to disrupt the bone-implant interface. The implant is then struck in a retrograde fashion with a square-tip impactor and mallet. The purpose of this study was to determine the characteristics and frequency of the different techniques needed for the removal of a well-fixed humeral stem in revision shoulder arthroplasty. Between 2010 and 2018, 288 revision shoulder arthroplasty procedures requiring removal of a well-fixed humeral component were carried out at a tertiary referral centre by a single surgeon. The patient demographics, indications for surgery, and method of extraction were collected.Aims

Nerve transfer has become a common and often effective reconstructive strategy for proximal and complex peripheral nerve injuries of the upper limb. This case-based discussion explores the principles and potential benefits of nerve transfer surgery and offers in-depth discussion of several established and valuable techniques including: motor transfer for elbow flexion after musculocutaneous nerve injury, deltoid reanimation for axillary nerve palsy, intrinsic re-innervation following proximal ulnar nerve repair, and critical sensory recovery despite non-reconstructable median nerve lesions.Abstract
Shoulder arthroplasty using short humeral components is becoming increasingly popular. Some such components have been associated with relatively high rates of adverse radiological findings. The aim of this retrospective review was to evaluate the radiological humeral bone changes and mechanical failure rates with implantation of a short cementless humeral component in anatomical (TSA) and reverse shoulder arthroplasty (RSA). A total of 100 shoulder arthroplasties (35 TSA and 65 RSA) were evaluated at a mean of 3.8 years (3 to 8.3). The mean age at the time of surgery was 68 years (31 to 90). The mean body mass index was 32.7 kg/m2 (17.3 to 66.4).Aims

The aim of this study was to evaluate the clinical and radiological outcomes of locking plate fixation, with and without an associated fibular strut allograft, for the treatment of displaced proximal humeral fractures in elderly osteoporotic patients. We undertook a retrospective comparison of two methods of fixation, using a locking plate without an associated fibular strut allograft (LP group) and with a fibular allograft (FA group) for the treatment of these fractures. The outcome was assessed for 52 patients in the LP group and 45 in the FA group, with a mean age of 74.3 years (52 to 89), at a mean follow-up of 14.2 months (12 to 19). The clinical results were evaluated using a visual analogue scale (VAS) score for pain, the Constant score, the American Shoulder and Elbow Surgeons (ASES) score, and the range of movement. Radiological results were evaluated using the neck-shaft angle (NSA) and humeral head height (HHH).Aims

The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years. We retrospectively studied the records of 79 patients (19 men, 60 women; 84 shoulders) aged 70.4 years (21 to 87) treated for aseptic loosening of the glenosphere following RSA. Clinical evaluation included pre- and post-treatment active anterior elevation (AAE), external rotation, and Constant score.Aims
Patients and Methods
The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair. All patients with a history of rotator cuff repair who underwent RSA between 2000 and 2015 with a minimum follow-up of two years were eligible for inclusion as the study group. Outcomes, including the American Shoulder and Elbow Surgeons (ASES) scores, were compared with a matched control group of patients who underwent RSA without having previously undergone rotator cuff repair.Aims

Controversy about the use of an anatomical total shoulder arthroplasty
(aTSA) in young arthritic patients relates to which is the ideal
form of fixation for the glenoid component: cemented or cementless.
This study aimed to evaluate implant survival of aTSA when used
in patients aged < 60 years with primary glenohumeral osteoarthritis (OA),
and to compare the survival of cemented all-polyethylene and cementless
metal-backed glenoid components. A total of 69 consecutive aTSAs were performed in 67 patients
aged < 60 years with primary glenohumeral OA. Their mean age
at the time of surgery was 54 years (35 to 60). Of these aTSAs,
46 were undertaken using a cemented polyethylene component and 23
were undertaken using a cementless metal-backed component. The age, gender,
preoperative function, mobility, premorbid glenoid erosion, and
length of follow-up were comparable in the two groups. The patients
