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 glenoid attrition (0.6%). Conclusion. To our knowledge there is no previous study with such a large population presenting demographic data and clinical outcome after shoulder arthroplasty. We found good results for the groups of patients diagnosed with osteoarthritis, arthritis and cuff arthropaty. There were poorer results in the groups of patient diagnosed with a proximal humeral fracture and especially caput necrosis

Aims. 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. Methods. 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. Results. Mean age at surgery was 67 years (24 to 90) and 445 (81%) patients were female. A complete questionnaire was returned by 364 (66%) patients at a mean follow-up of 10.6 years (8.8 to 13.8). Mean WOOS score was 64 (4.3 to 100.0). There was no correlation between WOOS scores and age, sex, arthroplasty brand, or year of surgery. The 14-year cumulative revision rate was 5.7% (confidence interval 4.1 to 7.2). Patients aged younger than 55 years and patients aged between 55 to 74 years had 5.6-times (2.0 to 9.3) and 4.3-times (1.9 to 16.7) higher risk of revision than patients aged older than 75 years, respectively. Conclusion. This is the largest long-term follow-up study of acute proximal humeral fractures treated with hemiarthroplasty. We found a low revision rate and an acceptable ten-year patient-reported outcome. The patient-reported outcome should be interpreted with caution as we have no information about the patients who died or did not return a complete WOOS score. The long-term outcome and revision rate suggest that hemiarthroplasty offers a valid alternative when non-surgical treatment is not possible. Cite this article: Bone Joint J 2021;103-B(6):1063–1069

We used an inverted shoulder arthroplasty in 43 consecutive patients with a mean age of 78 years (65 to 97) who had sustained a three- or four-part fracture of the upper humerus. All except two were reviewed with a mean follow-up of 22 months (6 to 58). The clinical outcome was satisfactory with a mean active anterior elevation of 97° (35° to 160°) and a mean active external rotation in abduction of 30° (0° to 80°). The mean Constant and the mean modified Constant scores were respectively 44 (16 to 69) and 66% (25% to 97%). Complications included three patients with reflex sympathetic dystrophy, five with neurological complications, most of which resolved, and one with an anterior dislocation. Radiography showed peri-prosthetic calcification in 36 patients (90%), displacement of the tuberosities in 19 (53%) and a scapular notch in ten (25%). Compared with conventional hemiarthroplasty, satisfactory mobility was obtained despite frequent migration of the tuberosities. However, long-term results are required before reverse shoulder arthroplasty can be recommended as a routine procedure in complex fractures of the upper humerus in the elderly

Objective. To compare regional body composition, bone mineral density (BMD), and clinical outcome in patients with two different shoulder arthroplasty designs. Materials and Methods. This cross-sectional study included 54 patients with a total of 63 shoulder arthroplasties. There were 18 men and 45 women with a mean age of 68.9 years SD ± 10.5. Mean follow-up time was 39.2 months SD ± 14.4. The patients were divided into three groups according to their history: 22 patients were diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty, 11 patients were diagnosed with osteoarthritis and treated with a stemmed hemi arthroplasty, and 30 patients were diagnosed with osteoarthritis and treated with a resurfacing arthroplasty. All patients underwent a one-day protocol: Regional Dual X-ray Absorptiometri (DXA) was used to measure BMD of the distal third of humerus and regional body composition of the upper arm. The clinical outcome was measured using Western Ontario Osteoarthritis of the Shoulder index (WOOS) and Constant-Murley score. Results. All three groups were comparable regarding demographic data. Mean BMD of the distal third of humerus was 1.029 g/cm2 SD ± 0.204, mean tissue mass of the upper arm was 2.6 kg SD ± 0.7 and mean muscle mass was 1.4 kg SD ± 0.6. BMD of the distal third of humerus, tissue mass and muscle mass were significantly higher in the group diagnosed with osteoarthritis and treated with a resurfacing arthroplasty compared to the group diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty, P = 0.03, P = 0.01 and P = 0.02 respectively. Median Constant score was 45.0, range 6–89, median WOOS 633, range 28–1824, and median strength 7.0 units, range 0–25. There were no significant differences between the three groups. Nevertheless, there was a trend towards a higher Constant-Murley score and muscle strength in the group of patients diagnosed with osteoarthritis and treated with a resurfacing arthroplasty compared to the group of patients diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty. Conclusion. After shoulder arthroplasty BMD of the distal third of humerus and body composition are apparently more dependent on diagnosis rather than arthroplasty design. However, a larger number of patients diagnosed with osteoarthritis and treated with a stemmed hemi arthroplasty are needed to support this

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 glenoid borders, fourteen stable inferior spurs, twenty-one inferior scapular notches including ten of them with medial proximal humeral bone loss or radio lucent lines between the bone and the cement were observed. Notches were more important in size when the follow-up was longer. 62% of the patients had worrying images.

The crossing of the clinical and radiological data showed a degradation of the mean Constant's score (41) for pain and strength in cases of notches with troubling proximal humeral images. In spite of only one case of aseptic loosening at 12 year follow-up, results are disappointing and complications and revisions rates important. The functional result is never equal to the pre-broken state. New developments in design, bearing surfaces and surgical technique and a more long term results will refine the role of the reverse concept for fracture.

Objectives. The PROximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial has recently demonstrated that surgery is non-superior to non-operative treatment in the management of displaced proximal humeral fractures. The objective of this study was to assess current surgical practice in the context of the PROFHER trial in terms of patient demographics, injury characteristics and the nature of the surgical treatment. Methods. A total of ten consecutive patients undergoing surgery for the treatment of a proximal humeral fracture from each of 11 United Kingdom hospitals were retrospectively identified over a 15 month period between January 2014 and March 2015. Data gathered for the 110 patients included patient demographics, injury characteristics, mode of surgical fixation, the grade of operating surgeon and the cost of the surgical implants. Results. A majority of the patients were female (66%, 73 of 110). The mean patient age was 62 years (range 18 to 89). A majority of patients met the inclusion criteria for the PROFHER trial (75%, 83 of 110). Plate fixation was the most common mode of surgery (68%, 75 patients), followed by intramedullary fixation (12%, 13 patients), reverse shoulder arthroplasty (10%, 11 patients) and hemiarthroplasty (7%, eight patients). The consultant was either the primary operating surgeon or supervising the operating surgeon in a large majority of cases (91%, 100 patients). Implant costs for plate fixation were significantly less than both hemiarthroplasty (p < 0.05) and reverse shoulder arthroplasty (p < 0.0001). Implant costs for intramedullary fixation were significantly less than plate fixation (p < 0.01), hemiarthroplasty (p < 0.0001) and reverse shoulder arthroplasty (p < 0.0001). Conclusions. Our study has shown that the majority of a representative sample of patients currently undergoing surgical treatment for a proximal humeral fracture in these United Kingdom centres met the inclusion criteria for the PROFHER trial and that a proportion of these patients may, therefore, have been effectively managed non-operatively.

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 glenoid. Tantalum beads were inserted into the humerus at the time of operation. RSA of the relaxed shoulder was completed at weeks 1, 6, 13, 26, 52 and 104 post-operatively. Stressed RSA with 12 newtons of abduction force was completed from week 13 onwards. ABRSA 5.0 software (Downing Imaging Limited, Aberdeen) was used to calculate humeral component migration and induced movement. 15 patients were recruited. Precision was: 0.041, 0.034, 0.086 and 0.101 mm for Superior, Medial, Posterior and Total Point Motion (TPM) respectively. The mean TPM over 2 years was 0.24 (0.30) mm, (Mean (Standard deviation)). The mean rate of migration per 3 month time period decreased from 0.45 (0.31) to 0.02 (0.01) mm over 2 years. Mean inducible movement TPM peaked at 26 weeks at 0.1 (0.08) mm, which reduced to 0.07 (0.06) mm by 104 weeks when only 3 patients had measurable inducible motion. There was no clear trend in direction of induced movement. There were no adverse events or revisions required. We conclude migration of the humeral component was low with little inducible movement in the majority of patients implying initial and 2 year stability of the stemless humeral component

Aims

Proximal humeral fractures (PHFs) are common. There is increasing evidence that most of these fractures should be treated conservatively. However, recent studies have shown an increase in use of operative treatment. The aim of this study was to identify the trends in the incidence and methods of treatment of PHFs in Finland.

Methods

The study included all Finnish inhabitants aged ≥ 16 years between 1997 and 2019. All records, including diagnostic codes for PHFs and all surgical procedure codes for these fractures, were identified from two national registers. Data exclusion criteria were implemented in order to identify only acute PHFs, and the operations performed to treat them.


Introduction. Reverse shoulder replacement is a surgical option for cuff tear arthropathy. However scapular notching is a concern. Newer designs of glenospheres are available to reduce scapular notching. Eccentric glenosphere with a lowered centre of rotation have been shown to improve range of adduction in vitro. We hypothesize that the eccentric glenosphere improve clinical outcomes and reduce scapular notching. Method. This is an ongoing randomized controlled double blind prospective clinical trial. Patients 70 years or older at North Shore hospital who have a diagnosis of cuff tear arthropathy and require surgery were consented for this study. Patients were allocated a concentric or eccentric 36 mm glenosphere intraoperatively, using a computer generated randomization contained in a sealed envelope. The surgical technique and post operative rehabilitation were standardized. Patients were followed up by a research nurse and postoperative radiographs were also taken at regular intervals. Clinical assessment include a visual analogue pain score, subjective shoulder rating, American Shoulder and Elbow Society Score, and Oxford shoulder score. Complications were checked for and radiographs were assessed for scapular notching. Results. There were 23 patients in the concentric and 24 patients in the eccentric glenosphere group. Average age and duration of follow up were comparable. There was no statistical significant difference but there was a trend towards better functional outcome and better range of motion in the eccentric glenosphere group. There was no scapular notching in the eccentric and three cases of scapular notching in the concentric glenosphere group. Conclusions. Reverse shoulder replacement significantly improve pain, function and range of motion in patients with cuff tear arthropathy. Eccentric glenosphere prevents scapular notching in the SMR reverse prosthesis

Aims

It is imperative to understand the risks of operating on urgent cases during the COVID-19 (SARS-Cov-2 virus) pandemic for clinical decision-making and medical resource planning. The primary aim was to determine the mortality risk and associated variables when operating on urgent cases during the COVID-19 pandemic. The secondary objective was to assess differences in the outcome of patients treated between sites treating COVID-19 and a separate surgical site.

Methods

The primary outcome measure was 30-day mortality. Secondary measures included complications of surgery, COVID-19 infection, and length of stay. Multiple variables were assessed for their contribution to the 30-day mortality. In total, 433 patients were included with a mean age of 65 years; 45% were male, and 90% were Caucasian.

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 glenoid and alter rotator cuff balance. The novel osteotomy resulted in more accurate recovery of head geometry and may improve clinical outcome

Introduction. Massive rotator cuff tears in the patient who is too young for a reverse shoulder replacement are a challenging situation. A technique using a ‘Grammont osteotomy’ of the acromion has been developed to allow a comprehensive approach, the so called “Full Monty”. Aim. To document the functional outcome of patients undergoing an acromial osteotomy for the repair of massive tears of the supraspinatus. Methods. Ten patients undergoing this procedure where entered in to the study. The mean age of the patients was 57 years (+/−16) and all bar one were male. Each patient had a pre-operative American Shoulder Elbow Score (ASES), Oxford Shoulder score (OSS), and range of movement documented. These outcome measures were repeated at a minimum of two years, as well as a patient satisfaction questionnaire. Results. The mean ASES preoperatively was 7(+/− 6) and 23(+/−3) post-operatively (p< 0.001). The mean pre-operative OSS was 22(+/−5) and 43(+/−4) post-operatively (p<0.001). 80% of patients deemed their treatment to be “successful” and 90% would recommend the procedure to a friend in the same plight. The mean post-operative forward flexion achieved was 153° (+/−58) and the mean abduction was 142° (+/−37). All patients could sustain a 1kg weight at arms length at 90° of abduction. One patient suffered a superficial wound infection and one patient had a non-union at the osteotomy site. Conclusion. These results suggest that this technique is a good surgical option for a patient with a “massive” rotator cuff tear that is not amenable to standard surgical techniques

Aims

The aims of this study were to investigate the mortality following a proximal humeral fracture. Data from a large population-based fracture register were used to quantify 30-day, 90-day, and one-year mortality rates after a proximal humeral fracture. Associations between the risk of mortality and the type of fracture and its treatment were assessed, and mortality rates were compared between patients who sustained a fracture and the general population.

Methods

All patients with a proximal humeral fracture recorded in the Swedish Fracture Register between 2011 and 2017 were included in the study. Those who died during follow-up were identified via linkage with the Swedish Tax Agency population register. Age- and sex-adjusted controls were retrieved from Statistics Sweden and standardized mortality ratios (SMRs) were calculated.

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 glenoid or humeral replacement or removal, or conversion to HA; - a poor clinical outcome defined by an absolute Constant score of less than 30. Results. At the time of review, 47 patients had died with their prosthesis in place and 30 were lost to follow-up. There were 12 revisions, 6 for infections, 3 for glenoid loosening, 1 for dislocation, 1 for glenoid dissociation (by unscrewing), and 1 for humeral loosening. The survival curve to prosthetic removal showed an overall survivorship of 92% at 10 years. Segmentation according to etiology showed a 97% survivorship for group A and 88% for group B This difference was not significant. No patients of group C had a minimum follow up of ten years because there were died or lost to follow up. The survival curve to a Constant score of less than 30 showed an overall survivorship of 90% at 10 years. Segmentation according to etiology showed a significant difference at 10 years in favor of group A (92%) compared to group B (86%) with a break of the curve after 9 years for group B. Discussion. Our results show that the overall survivorship of the reverse shoulder prosthesis to removal is good even 10 years after implantation, in particular if it had been implanted for CTA, OA, or MCT. However, functional results did deteriorate progressively after 9 years in particular if it had been implanted for revision (HA or TSA). Therefore, extreme caution must be observed in relation to the indications for reverse shoulder arthroplasty, especially in younger patients

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 glenoid component four times. Conclusion. We did not detect any statistically significant impact of previous insufficient shoulder arthroscopy for cuff tear reconstruction on the outcome and survival rate after the implantation of the inverted total shoulder prosthesis Delta. We conclude that reverse total shoulder arthroplasty with the Delta prosthesis is significantly beneficial in terms of less shoulder pain, higher stability and gain of range of motion without this beneficial effect being significantly weakened by previous insufficient shoulder arthroscopy for cuff tear reconstruction. We believe that previous arthroscopic cuff tear reconstruction should therefore be included in the treatment algorithm

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 glenoid significantly and negatively predicted the Constant score. Conclusion. CSRA of the shoulder outcomes have been comparable with those of stemmed arthroplasties. Radiolucent lines occur with follow up and most of the time located in the S1 area. Glenoid wear and humeral head lateralization negatively impact the clinical score. Cementless Shoulder resurfacing is a viable alternative to conventional shoulder arthroplasty

Gunshot injuries to the shoulder are rare and difficult to manage. We present a case series of seven patients who sustained a severe shoulder injury to the non-dominant side as a result of a self-inflicted gunshot wound. We describe the injury as ‘suicide shoulder’ caused by upward and outward movement of the gun barrel as the trigger is pulled. All patients were male, with a mean age of 32 years (21 to 48). All were treated at the time of injury with initial repeated debridement, and within four weeks either by hemiarthroplasty (four patients) or arthrodesis (three patients). The hemiarthroplasty failed in one patient after 20 years due to infection and an arthrodesis was attempted, which also failed due to infection. Overall follow-up was for a mean of 26 months (12 to 44). All four hemiarthroplasty implants were removed with no feasible reconstruction ultimately possible, resulting in a poor functional outcome and no return to work. In contrast, all three primary arthrodeses eventually united, with two patients requiring revision plating and grafting. These patients returned to work with a good functional outcome. We recommend arthrodesis rather than replacement as the treatment of choice for this challenging injury.

Secure fixation of displaced proximal fractures of the humerus is a challenging problem. A total of 32 patients with acutely displaced three- or four-part proximal fractures of the humerus were treated by open reduction and internal fixation using the proximal humeral internal locking system (PHILOS) plate. There were 23 women and nine men with a mean age of 59.9 years (18 to 87). Data were collected prospectively and the outcomes were assessed using the Constant score. The mean follow-up was for 11 months (3 to 24). In 31 patients (97%) the fracture united clinically and radiologically at a mean of 10 weeks (8 to 24). The mean Constant score at final review was 66.5 (30 to 92). There was no significant difference in outcome when comparing patients aged more than 60 years (18 patients) with those aged less than 60 years (14 patients) (t-test, p = 0.8443). There was one case each of nonunion, malunion and a broken screw in the elderly population.

This plate provides an alternative method of fixation for fractures of the proximal humerus. It provides a stable fixation in young patients with good-quality bone sufficient to permit early mobilisation. Failure of the screws to maintain fixation in the elderly remains a problem.
