In recent years, use of anatomic stemless total shoulder arthroplasty (AsTSA) has increased. Despite evidence to suggest good mid-term results at 2-year follow-up there is a paucity of evidence for longer term follow-up. This study aimed to investigate outcomes at a minimum of 5 years post-operatively following primary AsTSA. This study is a retrospective case series of all patients who underwent a Mathys Affinis AsTSA from July 2010 (first case) to August 2018 (to allow minimum 5-year follow-up). Clinical outcomes included revision rate, range of motion and patient reported outcomes (Oxford Shoulder Score and Numerical Satisfaction Score). Radiological outcome was assessment of radiolucent lines for Lazarus grading. A total of 105 stemless TSAs were implanted. Five patients underwent revision (4.8%). Seventy-five AsTSA's were included in the final study for analysis of 5-year outcomes. Median follow-up time was 6.1 years. Median age was 69 years old and 81% were female. Oxford shoulder score showed a range of 18 to 48, with a median score of 47. Satisfied or very Satisfied was selected in 94.37%. Median range of motion assessments showed forward elevation 160°, abduction 150°, external rotation 40°, and mode internal rotation was to the lumbar spine. No
Introduction. We aim to assess whether radiographic characteristics of the greater tuberosity fragment can predict rotator cuff tears inpatients with anterior shoulder dislocations combined with an isolated fracture of the greater tuberosity. Methods. A retrospective single-centre case series of 61 consecutive patients that presented with anterior shoulder dislocations combined with an isolated fracture of the greater tuberosity between January 2018 and July 2022. Inclusion criteria: patients with atraumatic anterior shoulder dislocation associated with an isolated fracture of the greater tuberosity with a minimum follow-up of 3-months. Exclusion criteria: patients with other fractures of the proximal humerus or

Over the last decade stemless shoulder arthroplasty has become increasingly popular. However, stability of metaphyseal loading humeral components remains a concern. This study aimed to assess the stability of the Affinis stemless humeral component using Radiostereometric analysis (RSA). Patients underwent total shoulder arthroplasty via a standardised technique with a press-fit stemless humeral component and a cemented pegged
First-time anterior dislocation of the shoulder is associated with the development of recurrent instability. It is recognised that patients with recurrent instability often have osseous defects. Using 3D computerised tomography (3DCT) it is possible to quantify these defects. Whether these defects are present after the primary dislocation or occur progressively from multiple dislocations is unclear. We correlated the presence of Hill-Sachs lesions and anterior glenoid bone loss with evidence of recurrent dislocation and clinical outcomes. 78 patients were followed up for two years. All underwent a 3DCT within a week of injury. Standardised images of the humeral head and
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. to analyze the survivorship of the RSA with a minimum 10 years follow up. Patients and Methods. Between 1992 and 1999, 145 Delta (DePuy) RSAs have been implanted in 138 patients. It was a mulicentric study. Initial etiologies were gathered as following: group A (92 cases) Cuff tear arthropaties (CTA), osteoarthritis (OA) with at least 2 involved cuff tendons, and massive cuff tear with pseudoparalysis (MCT); group B (39 cases) -failed hemiarthroplasties (HA), failed total shoulder arthroplasties (TSA), and fracture sequelae; and group C (14 cases) rheumatoid arthritis, fractures, tumor, and instability. Survival curves were established with the Kaplan-Meier technique. Two end-points were retained: -implant revision, defined by
Introduction. Osteoarthritis of the glenohumeral joint leads to global degeneration of the shoulder and often results in humeral or
There is no consensus on the treatment of proximal humeral fractures. Hemiarthroplasty has been widely used in patients when non-surgical treatment is not possible. There is, despite extensive use, limited information about the long-term outcome. Our primary aim was to report ten-year patient-reported outcome after hemiarthroplasty for acute proximal humeral fractures. The secondary aims were to report the cumulative revision rate and risk factors for an inferior patient-reported outcome. We obtained data on 1,371 hemiarthroplasties for acute proximal humeral fractures from the Danish Shoulder Arthroplasty Registry between 2006 and 2010. Of these, 549 patients (40%) were alive and available for follow-up. The Western Ontario Osteoarthritis of the Shoulder (WOOS) questionnaire was sent to all patients at nine to 14 years after primary surgery. Revision rates were calculated using the Kaplan-Meier method. Risk factors for an inferior WOOS score were analyzed using the linear regression model.Aims
Methods
We evaluated the results of Cementless Surface Replacement Arthroplasty (CSRA) of the shoulder in 67 patients with advanced glenohumeral destruction who have an intact rotator cuff. Between november 2002 and december 2008, 70 CSRA (32 Copeland/ Biomet and 38 SMRR/ Lima) were implanted in 67 patients. A deltopectoral approach was used in 34 cases and an anterosuperior approach in 36 cases. Patients were assessed using Constant score, a patient satisfaction score and a detailed radiographic analysis. The mean follow up was 3.4 years (range 1 to 7.5 years). The mean Constant score improved preoperatively from 17.6 points (range 2–55) to an average postoperative score of 66.1 (range 13–91). The pain score improved from 1.13 points (range 0–6) to 12.3 points (range 3–15). The forward flexion and external rotation improved from 71° (range 20 to 140) and 0° (range −40 to +45) to 143° (range 60 to180) and 34.4° (range −20 to +60) respectively. Complications included: 1 subscapularis detachment, 5 secondary rotator cuff tear, 1sepsis, 3 patients with shoulder stiffness. No shift in implant position was observed. 11 humeral components developed radiolucencies at the prosthesis-bone interface. The radiographic analysis involved a system of dividing the prosthesis/bone interface into 5 zones. The best clinical results were significantly achieved in patients with necrosis compared with osteoarthritis (Constant Score, ant. elevation, ext. Rotation). Using regression analysis we found that changes in the head-shaft angle position of the implant (valgus/varus placement of the CSRA) significantly predicted the age and sex adjusted Constant score. When the inclination angle of the humeral head decreases, the adjusted Constant score increases. In the same model, we also found that the lateral offset of the humerus significantly predicted the adjusted Constant score. When the lateral offset of the humerus decreases, the adjusted Constant score increases. The medialization of the

The aim of this retrospective study was to review a series of patients with ipsilateral fractures of the neck of the scapula and of the clavicle. Between 1991 and 1996 a total of 79 general and orthopaedic surgeons treated 46 patients with a floating shoulder in The Netherlands. The records and radiographs of these patients were studied. Of the 35 patients available for follow-up, 31 had initially been treated conservatively and four by operation; three underwent secondary reconstructive surgery. The mean Constant score for the 28 patients treated conservatively was 76 and for the seven treated operatively it was 71 at a mean follow-up of 35 months. In six of the 28 patients treated conservatively the
Shoulder arthroplasty is the treatment of choice for a range of degenerative diseases. However, long term follow-up suggests almost half of patients graded their treatment as unsatisfactory. Component malalignment is thought the most likely cause. The anterior anatomical neck is used as a reference for the osteotomy. The objective of the study was to analyse the cartilage/metaphyseal interface to identify reference points that may recover version accurately. Twenty-four humeri were scanned using a Microscribe digitiser and surface laser scanner. Modelling software was used to analyse the Cartilage/metaphyseal interface. The retroversion angle was calculated for the normal geometry and for the standard osteotomy. An ideal osteotomy plane was then created for each specimen and the distance from the cartilage/metaphyseal interface determined, identifying points of least deviation. The reference points were used to simulate a new osteotomy for which retroversion was calculated. The novel osteotomy and traditional osteotomy were compared to the normal geometry. The mean retroversion for the normal geometry was 18.5±9.0 degrees. The mean retroversion for the traditional osteotomy technique was 29.5±10.7 degrees, significantly different from the original (p<0.001). The mean retroversion using the novel osteotomy was 18.9±8.9 degrees and similar to the normal geometry (p=0.528). The traditional osteotomy resulted in a mean increase in retroversion of 38%. The increase in version may result in eccentric loading at the
This clinical study analyzes the long-term outcomes and potential complications of the Grammont's reverse prosthesis in case of trauma in elderly population. Between January 1993 and May 2010, thirty-seven consecutive patients with 26 three- and four-part fractures and 11 fracture-dislocations, mean age 75 (58 to 92) were evaluated with a mean follow-up of 7.3 years. Eight complications occurred: 2 complex sympathetic dystrophies, 3 dislocations, 2 deep infections and one aseptic loosening of the base-plate leading to 3 re-operations and 2 prosthesis revisions. The mean Constant's score dropped from 55 at two year follow-up to 52 (20 to 84) at last revision because of an augmentation of the pain and a diminution of the strength which represented 67% of the mean score for the injured side. Mean modified Constant's score was 68. Only 58% were satisfied or very satisfied because of poor internal and external rotations avoiding nourishment with utensils, dressing and personal hygiene when the dominant side was involved. Two complete
Introduction. Insufficient arthroscopic cuff tear reconstruction leading to massive osteoarthritis and irreparable rotator cuff tears might be salvaged by implantation of an inverted total shoulder prosthesis Delta in the elderly. However, despite the generally high success rate and satisfying clinical results of inverted total shoulder arthroplasty, this treatment option has potential complications. Therefore, the objective of this study was a prospective evaluation of the clinical and radiological outcome after a minimum of 2 years follow-up of patients undergoing inverted shoulder replacement with or without prior rotator cuff repair. Patients and Methods. Sixty-eight shoulders in 66 patients (36 women and 30 men) operated between February 2002 and June 2007 with a mean age of 66 years (ranging from 53 to 84 years) were first assessed preoperatively and then at minimum 2 years follow-up, using the Constant score for pain, Constant Shoulder Score, Oxford Shoulder Score, UCLA Shoulder rating scale, DASH Score, Rowe Score for Instability and Oxford Instability Score. 29 patients (Group A) had undergone previous shoulder arthroscopy for cuff tear reconstruction at a mean of 29 months (range 12 to 48 months) before surgery and 39 patients (Group B) underwent primary implantation of an inverted total shoulder prosthesis Delta. Any complications in both groups were assessed according to Goslings and Gouma. Results. We report statistically significant improvements of all obtained scores at a mean follow-up of 42 months (ranging from 24 to 96 months) in both groups. Significant outcome differences between 29 patients with previous shoulder arthroscopy for cuff tear reconstruction and 39 without previous shoulder arthroscopy were not observed. Eight complications occurred altogether, in terms of a nerve lesion once, loosening of the humeral stem three times, and loosening or fracture of the
Background. Acute anterior dislocation of the glenohumeral joint may be complicated by injury to neighboring structures. These injuries are best considered a spectrum of injury ranging from an isolated dislocation (unifocal injury), through injuries associated with either nerve or osteoligamentous injury (bifocal injury), to injuries where there is evidence of both nerve and osteoligamentous injury. The latter combination has previously been described as the “terrible triad,” although we prefer the term “trifocal,” recognizing that this is the more severe end of an injury spectrum and avoiding confusion with the terrible triad of the elbow. We evaluated the prevalence and risk factors for nerve and osteoligamentous injuries associated with an acute anterior glenohumeral dislocation in a large consecutive series of patients treated in our Unit. Materials and Methods. 3626 consecutive adults (mean age 48yrs) with primary traumatic anterior shoulder dislocation treated at our unit were included. All patients were interviewed and examined by an orthopaedic trauma surgeon and underwent radiological assessment within a week of injury. Where rotator cuff injury or radiologically-occult greater tuberosity fracture was suspected, urgent ultrasonography was used. Deficits in neurovascular function were assessed clinically, with electrophysiological testing reserved for equivocal cases. Results. Unifocal injuries occurred in 2228 (61.4%) of patients. There was a bimodal distribution in the prevalence of these injuries, with peaks in the 20–29 age cohort (34.4% patients) and after the age of 60 years (23.0% patients). Of the 1120 (30.9%) patients with bifocal dislocations, 920 (82.1%) patients had an associated osteotendinous injury and 200 (17.9%) patients had an associated nerve injury. Trifocal injuries occurred in 278 (7.7%) of cases. In bifocal and trifocal injuries, rotator cuff tears and fractures of the greater tuberosity or
Objective. To describe demographic data, clinical outcome and short-term survival after shoulder arthroplasty. Materials and Methods. The Danish Shoulder Arthroplasty Register was established in 2004. All 40 Danish hospitals and private clinics where shoulder arthroplasty are performed are participating. Since 2006 where the reporting to the register became mandatory the compliance of reporting has been 88.9%. Data are collected by an internet based clinical measuring system where the orthopaedic surgeon report data such as diagnosis, type of arthroplasty, and demographic data. The follow-up results are collected by sending a questionnaire to the patient 10–14 month after the operation. The questionnaire contains a Western Ontario Osteoarthritis of the Shoulder index (WOOS). Each question is answered on a visual analogue scale with a possible score ranging from 0–100. There are 19 questions and the total score is ranging from 0–1900. For simplicity of presentation the raw scores is converted to a percentage of a normal shoulder. Results. 2320 Shoulder arthroplasties were reported to the register between 2006 and 2008. There were 69.4% women. Median age was 70.6, range 16.3–96.3. 699 arthroplasties (30.0%) were due to osteoarthritis, 98 (4.2%) due to arthritis, 1182 (50.9%) due to a proximal humeral fracture, 179 (7.4%) due to rotator cuff arthropaty, 62 (2.7%) due to caput necrosis and 79 (3.4%) due to other pathology condition such as cancer and revision surgery. 1352 (58.3%) were stemmed hemi arthroplasty, 77 (3.3%) total shoulder arthroplasty, 596 (25.7%) resurfacing arthroplasty and 243 (10.5%) reverse shoulder arthroplasty. 1288 patients (55.5%) returned a complete questionnaire. Median WOOS for all arthroplasties was 58.2, range 0.0–100.0. Median WOOS for arthritis was 59.3, range 13.3–99.8, osteoarthritis 67.9, range 0.0–100.0, a proximal humeral fracture 54.2, range 0.0–100.0, rotator cuff arthropaty 65.6, range 0.0–98.3 and caput necrosis 48.9, range 3.9–95.2. 171 (7.4%) operations were revisions. The most common indications of revision were luxation (2.2%), infection (1.3%), loosening (0.7%) and
