Prosthetic replacement of the humeral head for fracture remains an operative challenge to even the most experienced orthopaedic surgeon. Although most fractures of the proximal humerus are minimally displaced and treated conservatively, more complex fractures require operative intervention. In this respect, the four-part proximal humerus fracture and fracture-dislocation have been difficult to evaluate and manage. Results from conservative treatment have been consistently unsatisfactory while results from surgery have been more variable with some series reporting satisfactory results. Treatment options for four-part fractures and fracturedislocations of the proximal humerus fractures include non-operative management, open reduction internal fixation, and humeral head replacement. Because of the poor results with non-operative, resection arthroplasty, and internal fixation, Neer in 1951 introduced prosthetic arthroplasty with tuberosity reconstruction for these complex fractures. Many reports in the literature have documented the successful results of this procedure. In our series of 65 shoulders there were 82% satisfactory results, 97% pain relief, and 85% good functional results. Therefore, prosthetic replacement of acute displaced fractures is technically demanding but offers a predictive result of a pain-free shoulder and functional motion through aggressive rehabilitation. Our goals in this video are to provide stepwise, comprehensive information on the techniques and guidelines for humeral head replacement in the treatment of complex proximal humerus fractures. Careful preoperative planning, patient evaluation, imaging, meticulous operative techniques, and a closely supervised rehabilitation program are necessary to produce a successful functional shoulder after prosthetic reconstruction

Introduction and Aims: The purpose of this study was to evaluate the effect on movement under load of different techniques of reattachment of the humeral tuberosities following four-part proximal humeral fracture. Method: Biomechanical test sawbones were used. Four-part fracture was simulated and a cemented Neer3 prosthesis inserted. Three different techniques of reattachment of the tuberosities were used: 1) tuberosities attached to the shaft, and to each other through the lateral fins in the prosthesis with one cerclage suture through the anterior hole in the prosthesis; 2) as one without cerclage suture; 3) tuberosities attached to the prosthesis and to the shaft. All methods used a number five ethibond suture. Both tuberosities and the shaft had multiple markers attached. Two digital cameras formed an orthogonal photogrammetric system, allowing all segments to be tracked in a 3-D axis system. Humeri were incrementally loaded in abduction using an Instron machine, to a minimum 1200N, and sequential photographs taken. Photographic data was analysed to give 3-D linear and angular motions of all segments with respect to the anatomically relevant humeral axis, allowing intertuberosity and tuberosity-shaft displacement to be measured. Results: Techniques one and two were the most stable constructs with technique three, allowing greater separation of fragments and angular movement. True inter-tuberosity separation at the midpoint of the tuberosities was significantly greater using technique three (p< 0.05). The cerclage suture used in technique two added no further stability to the fixation. Conclusion: Our model suggests that the most effective and simplest technique of reattachment involves suturing the tuberosities to each other, as well as to the shaft of the humerus. The cerclage suture appears to add little to the fixation in abduction, although the literature would suggest it may have a role in resisting rotatory movements

Introduction: The three or four-part fracture of the proximal humerus remains a challenging fracture in the case of elderly patient. In this continuing prospective study we compared the outcome after implantation of a shoulder hemiprosthesis of the anatomical generation and a reversed prosthesis. Material and methods: 34 shoulder prosthesis were implanted in patients older than 70 between june 1996 and june 2004. All patients were evaluated by a surgeon not involved in treatment concerning activities of daily living (DASH scoring), clinical outcome (Constant-Murley Score), radiological results, and a summary of complications. Group 1: anatomical prosthesis (Tornier): At an average follow-up of 16,5 (range 6–55) months, 13/17 patients with an average age of 78,6 years (70–95), were evaluated. Group 2: reversed prosthesis (Depuy): At an average follow-up of 12,6 (range 6–18) months, 13/17 patients with an average age of 77,1 years (70–84), were evaluated. In this group functional treatment was started immediately after surgery. Results: concerning age, follow up and dash scoring there were no difference between two groups. In reversed group : the outcome was better (Constant-Murley: 79,5 (57,8–100) vs 57,1 (21–85) p=0.005), the average active elevation was better by 30° (p< 0.001) and the average active abduction was better by 53° (p< 0.001). 7/13 cases of glenoid notching stage 2 or 3 were noted. In anatomical group : the average active external rotation was better by 10° (p=0.01). Tubercle fixations failed in 6/13 cases. Discussion: No comparative study has still been published between the two sort of implant in elderly patients. Our results of shoulder arthroplasty in acute injury to the proximal humerus with reversed prosthesis are in agreement with the preliminary results reported by Sirveau. At short follow up, reversed prosthesis allow to reach early mobilisation with best functional results. Rotation remains the key point : with a significant gain in active abduction and elevation the reversed prosthesis group do not reach a better dash scoring. Attachment fixation of the posterior rotator cuff must probably be discussed in reversed prosthesis in acute fracture

Abstract

Age is the most accurate surrogate for bone density and poor bone density is the reason for many fracture repairs to fail. Hemiarthroplasty has demonstrated consistently inconsistent results in terms for restoration of function. Most recently, with the evolution of reverse prostheses, prospective studies which are, in many cases, randomised and Level 2, have clearly shown reverse prostheses to be the most consistently reliable treatment in the patient noted above. It is with a high degree of certainty that we can inform such a patient that their function will be restored and their pain minimal with such treatment.

Management of 4-part fractures of the proximal humerus continues to challenge orthopaedic surgeons, shoulder surgeons, and trauma surgeons. Truly displaced 4-part fractures typically require surgery if the patient is medically able to undergo a surgical procedure. However, outcomes following surgery are not always as predictable as we would like. Results following hemiarthroplasty have led to more predictable pain relief than predictable functional recovery relying exclusively on the fate of tuberosity healing. Tuberosity healing failure leads to nearly universal catastrophic results with pain, dysfunction, and pseudoparalysis. Furthermore, conversion of failed hemiarthroplasty to reverse total shoulder arthroplasty leads to the highest incidence of complications and poorest outcomes of all groups of patients undergoing reverse total shoulder replacement. This is countered by the knowledge that if tuberosity healing occurs the outcome can be reliable with regard to pain relief and functional restoration.

Reverse total shoulder arthroplasty, on the other hand, has emerged as a preferred surgical option for many surgeons due to the issues following hemiarthroplasty. The increased prevalence of RTSA for the management of 4-part fractures has come without overwhelming evidence that outcomes are superior especially in light of the increased cost, life-time weight bearing restrictions, and uncertain long-term durability. Long-term follow-up of patients treated with RTSA for 4-part fracture has shown concerning degradation of function and outcomes and remains a valid concern about the long-term durability. We must remain diligent therefore in continuing to better understand which fractures should be treated non-operatively and those that may be amenable to anatomic hemiarthroplasty and finally those which may be better served by using a reverse total shoulder replacement.

Abstract. Reverse shoulder arthroplasty (RSA) is being increasingly used for complex, displaced fractures of the proximal humerus. The main goal of the current study was to evaluate the functional and radiographic results after primary RSA of three or four-part fractures of the proximal humerus in elderly patients. Between 2012 and 2020, 70 consecutive patients with a recent three- or four-part fracture of the proximal humerus were treated with an RSA. There were 41 women and 29 men, with a mean age of 76 years. The dominant arm was involved in 42 patients (60%). All surgeries were carried out within 21 days. Displaced three-part fracture sustained in 16 patients, 24 had fracture dislocation and 30 sustained a four-part fracture of the proximal humerus. Patients were followed up for a mean of 26 months. The mean postoperative OSS at the end of the follow-up period was 32.4. The mean DASH score was 44.3. Tuberosity non-union occurred in 18 patients (12.6%), malunion in 7 patients (4.9%), heterotopic ossification in 4 patients (2.8%) and scapular notching in one patient. Anatomical reconstruction was achieved in 25 patients (17.5%), the influence of greater tuberosity healing on shoulder function could not be demonstrated. Heterotopic ossification seems to affect OSS and QDASH, we found statistically significant relation between HO and clinical outcomes. Patients with heterotopic ossification had significantly lower postoperative scores on DASH and OSS (P = .0527). Despite expecting good functional outcome with low complication rate after RSA, the functional outcome was irrespective of healing of the tuberosities

Aim: To evaluate the radiographs of proximal humeral fractures in an attempt to define a diagnostic sign as a predictor of four-part fracture. Diagnostic sign: The normal humeral head articular surface points towards the glenoid. We describe our ‘sunset’ sign as ‘articular surface of humeral head pointing away from the glenoid and tilted upwards, in the presence of a displaced greater tuberosity fracture’. We postulate that a patient with proximal humerus fracture showing this sign has four-part fracture until proved otherwise. Materials and Methods: Between 2002 and 2006, 80 consecutive patients underwent open reduction and internal fixation of their proximal humeral fractures in our Shoulder unit. We reviewed their preoperative radiographs and operative notes retrospectively. 79 patients were included in the study as one patient’s pre-operative radiograph was not available. The AP radiograph was evaluated independently by three observers who were blinded to the identity of the patients and their operative diagnosis. The presence of ‘sunset’ sign was recorded. There was 90% inter-observer agreement. In the remaining 10%, a consensus review was performed as to the presence of sign for evaluation purpose. The findings were then correlated with the operative findings to confirm whether they were four-part fractures or not. With 95% confidence interval we calculated the sensitivity, specificity, and positive and negative predictive values for our diagnostic sign. Results: 30 out of 79 patients displayed ‘sunset’sign in their preoperative radiograph. Of these 28 had confirmed four-part fractures operatively. The positive predictive value of ‘sunset’ sign in diagnosis the four-part fracture was 93%. The specificity and sensitivity were 95% and 78% respectively. The sensitivity was affected by 8 patients with four part fractures with displaced articular head fragment which had dropped either medially or posteriorly. Conclusion: Our results suggest that in patients with proximal humeral fractures, the presence of ‘sunset’sign in the anteroposterior radiograph is a reliable indicator of four-part fracture

Introduction. There is considerable uncertainty about the optimal treatment of displaced four-part fractures of the proximal humerus. Within the last decade locking plate technology has been considered a breakthrough in the treatment of these complex injuries. Methods. We systematically identified and reviewed clinical studies of the benefits and harms after osteosynthesis with locking plates in displaced four-part fractures. Results. We included fourteen studies with 374 four-part fractures. There were no randomised trials, one prospective observational comparative study, three retrospective observational comparative studies, and ten case series. Small studies with a high risk of bias precluded reliable estimates of functional outcome. Unexpected high rates of complications (range 16% to 64%) and re-operations (range 11% to 27%) were reported. Conclusion. The empirical foundation for the clinical value of locking plates in displaced four-part fractures of the proximal humerus is very sketchy. We emphasise the need for well conducted randomised trials and observational studies

Aim: To evaluate the radiographs of proximal humeral fractures in an attempt to define a diagnostic sign as a predictor of four-part fracture. Diagnostic sign The normal humeral head articular surface points towards the glenoid. We describe our ‘sunset’ sign as ‘articular surface of humeral head pointing away from the glenoid and tilted upwards, in the presence of a displaced greater tuberosity fracture’.

The presence of ‘sunset’ sign was recorded. A consensus review was performed for evaluation purpose. The findings were then correlated with the operative findings. With 95% confidence interval we calculated the sensitivity, specificity, and positive and negative predictive values for our diagnostic sign. Results: Thirty patients displayed ‘sunset’sign in their radiograph. Of these 28 had confirmed four-part fractures operatively. The positive predictive value of ‘sunset’ sign in diagnosis of four-part fracture was 93%. The specificity and sensitivity were 95% and 78% respectively. The sensitivity was affected by 8 patients with four part fractures with displaced articular head fragment which had dropped either medially or posteriorly. There were substantial interobserver and intraobserver agreement as measured by kappa coefficient (0.62 and 0.70). Conclusion: Our results suggest that in patients with proximal humeral fractures, the presence of ‘sunset’sign in the anteroposterior radiograph is a reliable indicator of four-part fracture

Objectives. The objective of this study was to perform a meta-analysis of all randomised controlled trials (RCTs) comparing surgical and non-surgical management of fractures of the proximal humerus, and to determine whether further analyses based on complexity of fracture, or the type of surgical intervention, produced disparate findings on patient outcomes. Methods. A systematic review of the literature was performed identifying all RCTs that compared surgical and non-surgical management of fractures of the proximal humerus. Meta-analysis of clinical outcomes was performed where possible. Subgroup analysis based on the type of fracture, and a sensitivity analysis based on the type of surgical intervention, were also performed. Results. Seven studies including 528 patients were included. The overall meta-analysis found that there was no difference in clinical outcomes. However, subgroup and sensitivity analyses found improved patient outcomes for more complex fractures managed surgically. Four-part fractures that underwent surgery had improved long-term health utility scores (mean difference, MD 95% CI 0.04 to 0.28; p = 0.007). They were also less likely to result in osteoarthritis, osteonecrosis and non/malunion (OR 7.38, 95% CI 1.97 to 27.60; p = 0.003). Another significant subgroup finding was that secondary surgery was more common for patients that underwent internal fixation compared with conservative management within the studies with predominantly three-part fractures (OR 0.15, 95% CI 0.04 to 0.63; p = 0.009). Conclusion. This meta-analysis has demonstrated that differences in the type of fracture and surgical treatment result in outcomes that are distinct from those generated from analysis of all types of fracture and surgical treatments grouped together. This has important implications for clinical decision making and should highlight the need for future trials to adopt more specific inclusion criteria. Cite this article: S. Sabharwal, N. K.

Two-part surgical neck fractures, two-part greater tuberosity fractures and three- and four-part fractures of the proximal humerus represent a frequently encountered clinical problem. Many types of conservative treatments have been proposed, with a poor functional outcome, however; when the fracture fragments are displaced, surgery is required. Because the open reduction and the internal fixation disrupts soft tissue and increases the risk of avascular necrosis of the humeral head, closed or minimally open reduction and percutaneous pin fixation should represent an advantage. We report on 31 patients affected by fractures of the proximal humerus (n=6, two-part surgical neck fractures; n=5, with two-part greater tuberosity fractures; n=10, three-part fractures; and n=11, four- part fractures) treated with minimally open reduction and percutaneous fixation. The average age was 57 years. Most of the four-part fractures were of the valgus type with no significant lateral displacement of the articular segment. A small skin incision was performed laterally at the shoulder and a rounded-tipped instrument was introduced to obtain the fracture reduction; this latter was stabilised by percutaneous pins and cannulate screws. A satisfactory reduction was achieved in most cases. The average follow-up was 24 months (range 18–47). Only one patient, with four-part fractures associated with lateral displacement of the humeral head, showed avascular necrosis and received a prosthetic implant. Minimally open reduction and percutaneous fixation is a non-invasive technique with a low risk of avascular necrosis and infection. This surgical technique allows a stable reduction with minimal soft tissue disruption and facilitates postoperative mobilisation

Optimal surgical management of proximal humeral fractures remains controversial. We report our experience and the study on our surgical technique for proximal humeral fractures and fracture-dislocations using locking plates in conjunction with calcium sulphate augmentation and tuberosity repair using high strength sutures. We used the extended deltoid-splitting approach for fracture patterns involving displacement of both lesser and greater tuberosities and for fracture-dislocations. We retrospectively analysed 22 proximal humeral fractures in 21 patients. 10 were male and 11 female with an average age of 64.6 years (Range 37 to 77). Average follow-up was 24 months. Fractures were classified according to Neer and Hertel systems. Pre-operative radiographs and CT scans in three and four-part fractures were done to assess the displacement and medial calcar length for predicting the humeral head vascularity. According to the Neer classification, there were 5 two-part, 6 three-part, 5 four-part fractures and 6 fracture-dislocations (2 anterior and 4 posterior). Results were assessed clinically with DASH scores, modified Constant & Murley scores and serial post-operative radiographs. The mean DASH score was 16.18 and modified Constant & Murley score was 64.04 at the last follow-up. 18 out of 22 cases achieved good clinical outcome. All the fractures united with no evidence of infection, failure of fixation, malunion, tuberosity failure, avascular necrosis or adverse reaction to calcium sulphate bone substitute. There was no evidence of axillary nerve injury. The CaSO4 bone substitute was replaced by normal appearing trabecular bone texture at an average of 6 months in all patients

Fractures of proximal humerus account for nearly 5% of all fractures. Majority of these fractures are minimally displaced and can be treated non-operatively with good functional results. However, treatment of unstable, displaced and comminuted fractures remains a challenge and optimal treatment continues to be controversial. This study was undertaken to evaluate the results of proximal humeral internal locking system (PHILOS) plating done for treatment of displaced three- and four-part fractures of the proximal humerus. Between November 2003 and February 2008, a total of 36 patients with displaced three- and four-part fractures of the proximal humerus had an open reduction and internal fixation using a PHILOS plate. Data was collected retrospectively and clinical and radiological outcomes were assessed. The mean follow up was 18 months. 35 (97.2%) united clinically and radiologically, with a mean neck/shaft angle of 127.1 degrees. One patient (2.8%) had revision procedure for implant failure, with a longer PHILOS plate and bone graft. The mean time to union was 9 weeks (7 to 20). The mean Constant score at final review was 72.1 (36 to 96). A total of 16 patients (44.4%) had excellent outcome, 16 (44.4%) had satisfactory outcome, but in four (11.2%) the outcome was poor. The PHILOS plate provides good fracture stability early-on allowing early mobilisation without compromising fracture union. It requires minimal soft tissue dissection, does not need contouring and angular screw fixation gives good stability. We stress the importance of minimal soft tissue dissection to preserve the vascularity of the head, indirect methods of reduction and early mobilization

The management of three or four-part fractures of proximal Humerus remains difficult. Controversy still persists concerning the preferred treatment of these fractures. The aim of our study was to review the functional outcome and factors influencing the outcome after shoulder hemi arthroplasty in acute fractures of proximal humerus. Material and Methods: Retrospective review of a consecutive series of 23 patients with three/four-part proximal humerus fractures, treated with shoulder hemi-arthroplasty between 1999 – 2002. Nineteen patients (one bilateral) were available for study. The mean follow-up period was 12 months. All fractures, 16 cases were Neer’s four-part fractures, while one case was fracture with posterior dislocation. Post operative pain, range of motion and function evaluated using Visual analogue score, Pain scale and UCLA functional score. The average age was 64 years (range 50–85). Results: At follow-up pain relief was satisfactory in 15 of 20 cases. Patient’s satisfaction was 75%. Functional evaluation was good/fair in 14 cases. One patient developed chronic inferior subluxation post-operatively. We have found that age (75 years +) at the time of surgery, securing of tuberosities t the implant and compliance with the post-operative rehabilitation program are significant factors affecting the outcome. Conclusion: We recommend careful patient selection, proper positioning of patient during surgery, use of x-ray screening of the implant prior to cementing and meticulous surgical technique to achieve optimal results

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 deltopectoral approach, indirect reduction, secure suture repair of the tuberosities and fixation with locking plate. The minimum follow up was 3 years. There were 9 two-part, 19 three-part and 22 four-part fractures. Their average age was 63 years. All patients were assessed objectively with Constant score and subjectively with Oxford questionnaire by an independent observer. Fracture healing and complications were recorded. Results: 47 patients were available for follow-up. All fractures united. The average Constant score was 84. Their mean Oxford score was 16. There was no infection or metal work failure. One patient fractured below the plate after a fall but went onto uneventful union. 4 of 47 patients (8.5%) developed avascular necrosis. Three were four-part fracture and one was two-part fracture. Three patients underwent hemiarthroplasty of shoulder with good functional recovery. One patient declined further operative intervention due to low level of symptoms. Conclusion: Indirect reduction and secure fixation of the tuberosities onto the humeral head with a locking plate is a reliable technique of treating displaced proximal humeral fractures. Our experience of avascular necrosis in only 8.5% of these fractures is much lower than any reported series after open surgery

Percutaneous fixation is a well recognised technique in the treatment of three-part and four-part fractures of the proximal humerus. Minimal fixation of these fractures do show good functional outcome and may further reduce the incidence of avascular complications. We report a preliminary series of 11 patients who underwent percutaneous minimal fixation of such complex humeral fractures using a new technique. 11 consecutive patients (7 with three-part fractures and 4 with four-part fractures) treated by percutaneous limited fixation in our Hospital were involved in this retrospective study. There were 7 fractures with valgus displacement. Percutaneous technique was employed using small incisions and the fracture was reduced under image guidance. The three-part and the four-part fractures were essentially converted into two part fractures, i.e. only the greater and the lesser tuberosities were re-attached to head with AO cancellous screws after realignment of the fragments. The shaft of the humerus was not fixed to the head in any of the cases. All of these cases had a minimum follow-up of at least 6 months. The results were evaluated using the Constant -Murley Shoulder score. 1 out of 11 cases had to be converted to hemi-arthroplasty due to secondary redisplacement of the fracture. The remaining 10 cases showed good bony union although the greater tuberosity in 2 cases showed a residual superior displacement of 3mm and a residual valgus displacement in 2 out of 7 cases. There were no complications of avascular necrosis in any of the cases. Clinically, compared to the uninjured side the average constant score was 93.7% (range- 68.7% – 100%). 7 patients were very satisfied and 4 were satisfied with the operation. Percutaneous minimal fixation achieves good to very good functional outcome comparable to the conventional methods and theoretically reduces the incidence of infection, avascular necrosis and neurological complications

Objectives and Material: The authors have evaluated 78 patients with fractures of the proximal humerus that have been interned in the Orthopedics’ Service at Hospital de Santa Maria since the 1st January of 1995 until the 31st December of 1999 with the objective of evaluating different factors influencing the final results and concluding to the best therapeutic conduct in the different cases. Method: The following parameters have been evaluated: sex, age, accident type (low/high energy), associated injuries, fracture’s classification, type of treatment and results achieved. The Constant score have been used for the functional evaluation. Due to reduced number of patients in each class a non-parametric test has been used – Qui-square test (X2). SPSS program has been used to run the calculations. Results: It has been verified that sixty four percent of the cases happened due to low energy accidents and the three-part fractures prevailed (46%), followed by four-part fractures (34%). The fracture of the proximal humerus occurred isolated and prevailed in women above 60 years old. Patients’ age was not a factor of bad prognostic. The number of bad results depended on the fracture’s type. Open reduction and internal fixation has been the most frequently used technique in all fracture types and the one with the best results. Open reduction and Kirschner pinning should be used only in very specific cases and with limited functional objectives. Humeral head reconstruction has not been a valid option to four-part fractures treatment, allowing concluding that, in many cases of very fragmented fractures, the option for the humeral head substitution by prosthesis should be better than trying its reconstruction
