Aims. The outcomes following nonoperative management of minimally displaced greater tuberosity (GT) fractures, and the factors which influence patient experience, remain poorly defined. We assessed the early patient-derived outcomes following these injuries and examined the effect of a range of demographic- and injury-related variables on these outcomes. Methods. In total, 101 patients (53 female, 48 male) with a mean age of 50.9 years (19 to 76) with minimally displaced GT fractures were recruited to a prospective observational cohort study. During the first year after injury, patients underwent experiential assessment using the Disabilities of the Arm, Shoulder and Hand (DASH) score and assessment of associated injuries using MRI performed within two weeks of injury. The primary outcome was the one-year DASH score. Multivariate analysis was used to assess the effect of patient demographic factors, complications, and associated injuries, on outcome. Results. The mean DASH score improved from 42.3 (SD 9.6) at six weeks post-injury, to 19.5 (SD 14.3) at one-year follow-up (p < 0.001), but outcomes were mixed, with 30 patients having a DASH score > 30 at one year. MRI revealed a range of associated injuries, with a full-thickness rotator cuff tear present in 19 patients (19%). Overall, 11 patients (11%) developed complications requiring further operative intervention; 20 patients (21%) developed post-traumatic secondary shoulder stiffness. Multivariate analysis revealed a high-energy mechanism (p = 0.009), tobacco consumption (p = 0.033), use of mobility aids (p = 0.047), a full-thickness rotator cuff tear (p = 0.002), and the development of post-traumatic secondary shoulder stiffness (p = 0.035) were independent predictors of poorer outcome. Conclusion. The results of nonoperative management of minimally displaced GT fractures are heterogeneous. While many patients have satisfactory early outcomes, a substantial subgroup fare much worse. There is a high prevalence of rotator cuff injuries and post-traumatic shoulder stiffness, and their presence is associated with poorer patient experience. Furthermore, patients who have a high-energy injury, smoke, or use walking aids, have worse outcomes. Cite this article: Bone Joint J 2023;105-B(5):534–542

Purpose of study. The outcomes of conservatively managed minimally displaced isolated greater tuberosity fractures are sparsely reported and the aim of this study was to look at the outcome of these fractures. patients and methods. Twenty-seven patients who had sustained a greater tuberosity fracture were identified. They were all managed by a single surgeon. All patients had a regime of initial immobilisation for 3 weeks followed by physiotherapy and range of motion exercises. They were all x-rayed at 1 week and 3 weeks after injury to monitor for any displacement. Four fractures occurred with an anterior dislocation. In seven patients the fracture was not visible on x-ray but was diagnosed on Ultrasound or MRI. Twenty-three of 27 patients were available for follow-up. For this follow up, the patients were telephonically contacted and the Oxford Shoulder Score (OSS) was completed to assess their outcome. Results. There were 12 males and 11 females in the review. The average age was 44 yrs (6–71 yrs) and the average follow up was 26.2 months (6–43 months). The OSS for the 23 patients ranged from 22–48 (average 44, median 47, mode of 48). Fourteen patients had LASI as part of their management after they started to develop pain and impingement symptoms. The ones with LASI had a slightly lower median OSS (46) compared to those without (48) but the modal scores were the same (48). One patient needed surgery after the initial fracture displaced at 3 weeks while another patient needed an acromioplasty at 10 months for impingement. Three patients developed a frozen shoulder but subsequently settled and had excellent outcome scores. Summary. In this study, 30% (7) of the fractures were not visible on the x-rays but diagnosed on ultrasound or MRI. Nearly half the patients required subacromial steroid injections to improve recovery. In only one patient did the fracture displace and require fixation. Conclusion. Conservative management of minimally displaced greater tuberosity fractures yields good functional results though a high percentage of patients require subacromial steroid injections. Secondary displacement is rare, however close vigilance of fracture is advised with x-rays done at 1 and 3 weeks postoperatively. NO DISCLOSURES

In this study, we describe a morphological classification for greater tuberosity fractures of the proximal humerus. We divided these fractures into three types: avulsion, split and depression. We retrospectively reviewed all shoulder radiographs showing isolated greater tuberosity fractures in a Level I trauma centre between July 2007 and July 2012. We identified 199 cases where records and radiographs were reviewed and included 79 men and 120 women with a mean age of 58 years (23 to 96). The morphological classification was applied to the first 139 cases by three reviewers on two occasions using the Kappa statistic and compared with the AO and Neer classifications. The inter- and intra-observer reliability of the morphological classification was 0.73 to 0.77 and 0.69 to 0.86, respectively. This was superior to the Neer (0.31 to 0.35/0.54 to 0.63) and AO (0.30 to 0.32/0.59 to 0.65) classifications. The distribution of avulsion, split and depression type fractures was 39%, 41%, and 20%, respectively. This classification of greater tuberosity fractures is more reliable than the Neer or AO classifications. These distinct fracture morphologies are likely to have implications in terms of pathophysiology and surgical technique. Cite this article: Bone Joint J 2014;96-B:646–51

Aims. The risk factors for recurrent instability (RI) following a primary traumatic anterior shoulder dislocation (PTASD) remain unclear. In this study, we aimed to determine the rate of RI in a large cohort of patients managed nonoperatively after PTASD and to develop a clinical prediction model. Methods. A total of 1,293 patients with PTASD managed nonoperatively were identified from a trauma database (mean age 23.3 years (15 to 35); 14.3% female). We assessed the prevalence of RI, and used multivariate regression modelling to evaluate which demographic- and injury-related factors were independently predictive for its occurrence. Results. The overall rate of RI at a mean follow-up of 34.4 months (SD 47.0) was 62.8% (n = 812), with 81.0% (n = 658) experiencing their first recurrence within two years of PTASD. The median time for recurrence was 9.8 months (IQR 3.9 to 19.4). Independent predictors increasing risk of RI included male sex (p < 0.001), younger age at PTASD (p < 0.001), participation in contact sport (p < 0.001), and the presence of a bony Bankart (BB) lesion (p = 0.028). Greater tuberosity fracture (GTF) was protective (p < 0.001). However, the discriminative ability of the resulting predictive model for two-year risk of RI was poor (area under the curve (AUC) 0.672). A subset analysis excluding identifiable radiological predictors of BB and GTF worsened the predictive ability (AUC 0.646). Conclusion. This study clarifies the prevalence and risk factors for RI following PTASD in a large, unselected patient cohort. Although these data permitted the development of a predictive tool for RI, its discriminative ability was poor. Predicting RI remains challenging, and as-yet-undetermined risk factors may be important in determining the risk. Cite this article: Bone Joint J 2024;106-B(10):1111–1117

A fracture of the tuberosity is associated with 16% of anterior glenohumeral dislocations. Manipulation of these injuries in the emergency department is safe with less than 1% risk of fracture propagation. However, there is a risk of associated neurological injury, recurrent instability and displacement of the greater tuberosity fragment. The risks and outcomes of these complications have not previously been reported. The purpose of this study was to establish the incidence and outcome of complications associated with this pattern of injury. We reviewed 339 consecutive glenohumeral dislocations with associated greater tuberosity fractures from a prospective trauma database. Documentation and radiographs were studied and the incidence of neurovascular compromise, greater tuberosity fragment migration and intervention and recurrent instability recorded. The mean age was 61 years (range, 18–96) with a female preponderance (140:199 male:female). At presentation 24% (n=78) patients had a nerve injury, with axillary nerve being most common (n=43, 55%). Of those patients with nerve injuries 15 (19%) did not resolve. Greater tuberosity displacement >5mm was observed in 36% (n=123) of patients with 40 undergoing acute surgery, the remainder did not due to comorbidities or patient choice. Persistent displacement after reduction accounted for 60 cases, later displacement within 6 weeks occurred in 63 patients. Recurrent instability occurred in 4 (1%) patients. Patient reported outcomes were poor with average EQ5D being 0.73, QDASH score of 16 and Oxford Shoulder Score of 41. Anterior glenohumeral dislocation with associated greater tuberosity fracture is common with poor long term patient reported outcomes. Our results demonstrate there is a high rate of neurological deficits at presentation with the majority resolving spontaneously. Recurrent instability is rare. Late tuberosity fragment displacement occurs in 18% of patients and regular follow-up for 6 weeks is recommended to detect this

Glenohumeral dislocation is complicated with a greater tuberosity fracture in 16% of cases. Debate regarding the safety of closed reduction in the emergency department exists, with concerns over fracture propagation during the reduction manoeuvre. The study aim was to report the results of closed reduction, identify complications and define outcome for these injuries. 188 consecutive glenohumeral dislocations with a tuberosity fracture were identified from a prospective database from 2014–2017. 182 had an attempted closed reduction under appropriate sedation using standard techniques, five were manipulated in theatre due to contra-indications to sedation. Clinical, radiographic and patient reported outcomes, in the form of the QuickDASH and Oxford Shoulder Score (OSS), were collected. A closed reduction in the emergency department was successful in 162 (86%) patients. Two iatrogenic fractures of the proximal humerus occurred, one in the emergency department and one in theatre, representing a 1% risk. 35 (19%) of patients presented with a nerve lesion due to dislocation. Surgery was performed in 19 (10%) cases for persistent or early displacement (< 2 weeks) of the greater tuberosity fragment. Surgery resulted in QuickDASH and OSS scores comparable to those patients in whom the tuberosity healed spontaneously in an anatomical position (p=0.13). 18 patients developed adhesive capsulitis (10%). Glenohumeral dislocation with greater tuberosity fracture can be safely treated by closed reduction within the emergency department with a low risk of humeral neck fracture. Persistent or early displacement of the tuberosity fragment will occur in 10% of cases and is an indication for surgery

Abstract. Introduction. There is little literature exploring clinical outcomes of secondarily displaced proximal humerus fractures. The aim of this study was to assess the rate of secondary displacement in undisplaced proximal humeral fractures (PHF) and their clinical outcomes. Methods. This was a retrospective cohort study of undisplaced PHFs at Royal Derby Hospital, UK, between January 2018-December 2019. Radiographs were reviewed for displacement and classified according to Neer's classification. Displacement was defined as translation of fracture fragments by greater than 1cm or 20° of angulation. Patients with pathological, periprosthetic, bilateral, fracture dislocations and head-split fractures were excluded along with those without adequate radiological follow-up. Results. In total, 681 patients were treated with PHFs within the study period and out of those 155 were excluded as above. There were 385 undisplaced PHFs with mean age 70 years (range, 21–97years) and female to male ratio of 3.3:1. There were 88 isolated greater tuberosity fractures, 182 comminuted PHFs and 115 surgical neck fractures. Secondary displacement occurred in 33 patients (8.6%). Mean time to displacement was 14.8 days (range, 5–45days) with surgical intervention required in only 5 patients. In those managed nonoperatively, three had malunion and one had nonunion. No significant differences were noted in ROM between undisplaced and secondarily displaced PHFs. Conclusion. Undisplaced fractures are the most common type of PHF. Rate of secondary displacement is low at 8.6% and can occur up to 7 weeks after injury. Displacement can lead to surgery, but those managed conservatively maintain their ROM at final follow up

Introduction. Surgical fixation of greater tuberosity fractures in the shoulder is the choice of treatment even if the fragment is minimally displaced. This helps to reduce the incidence of impingement secondary to a malunited tuberosity fragment especially in younger patients. We evaluated the functional outcome of our patients treated with open reduction and internal fixation of these fractures using cancellous screws. Materials and Methods. 19 patients with a mean age of 57.1 years (range 27–84) with 19 isolated greater tuberosity fractures treated with cancellous screws were included. These patients were evaluated after an average follow up period of nearly four years (range 66–444 weeks) using the DASH score and the Constant and Murley score. They were also clinically assessed to check for signs of impingement. Results. The median age in our study was 59. The mean Constant and Murley score was 75 (range 35–98) and the mean DASH score was 15.7 (0.8–45.0) which is a good result. Most patients had trouble in performing overhead activities (as per the DASH scoresheet) inspite of surgery. Impingement signs were also positive in nearly half of our patients (9 patients). Conclusions. Greater tuberosity fracture fixation using cancellous screws is a simple procedure associated with good results. However comparision needs to be made with the outcomes following fixation using suture anchors which is also a popular technique

Aims. Isolated greater tuberosity fractures make up 17–21% of proximal humeral fractures, 30% are associated with shoulder dislocation. Conservative management of minimally displaced fractures (<5 mm) is recommended. There are few guides to which and how many fractures displace over time. Methods. A retrospective analysis of isolated greater tuberosity fractures presenting to a shoulder fracture clinic over 1 year was performed. Patients were identified from shoulder fracture clinic lists and a bluespier database. Radiological fracture displacement was measured from the edge of the defect in the humeral head to the closest edge of the greater tuberosity. All measurements were performed by three oberservers on two occasions. Data was analysed to study the relationship between initial displacement and fracture stability and between concurrent dislocation and fracture stability. Inter-observer analysis was performed. Results. 64 (m:32; f:32; mean age 53) patients were identified. 37 were displaced 0–5 mm at presentation, 18 were displaced 5–10 mm, 9 were displaced >10 mm. Of those displaced less than 5 mm on presentation, 22% (n8) further displaced to greater than 5 mm and 5% (n2) to >10 mm at follow-up. Of those displaced 5–10 mm on presentation, 17% (n3) displaced to >10 mm. 42% (n27) of fractures were associated with dislocation; they had greater displacement at presentation. In the 0–5 mm displacement group that displaced >5 mm, 88% (n7) had concurrent dislocation. Inter-observer analysis of the x-ray measurement showed moderate agreement (0.684). Conclusion. Isolated greater tuberosity fractures displaced less than 5 mm at presentation and that are not associated with dislocation are stable. Concurrent dislocation is associated with both greater fracture displacement at presentation and ongoing fracture instability

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

We conducted a prospective evaluation of patients with anterior dislocation of the shoulder associated with a fracture of the greater tuberosity. Thirty-four anterior dislocations of the shoulder with greater tuberosity fractures were reviewed with a minimum follow-up of one year from the time of injury. Eight required open reduction. The final outcome with regard to pain, range of movements, and function was assessed in 34 patients. In open reduction, there were five good results, one fair, one poor and one patient died. In the non-operative group, results were good in 11 patients, fair in eight, poor in one, not assessed in five and one patient died. Two patients have died in this series, one in the open reduction group. Associated injuries are: axillary nerve damage (three), brachial plexus injury (one), loose fragment under the acromion (one) and stiffness of the shoulder (three). Anterior dislocations of the shoulder with fracture of the greater tuberosity do not always lead to good results. Close observation after reduction is important to check for later displacement of the fractures

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. The AP radiograph was evaluated independently by three observers who were blinded to the operative diagnosis. 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

Proximal humerus fracture treatment remains controversial. If the conservative treatment is widely accepted for Neer I and Neer II fractures, the attitude is not very clear concerning Neer III and Neer IV fractures. Several methods are proposed in the literature varying from suturing, pinning or plating the proximal humerus. Hemiarthroplasty are even considered. In our study we present our results of an internal fixation procedure for 3 part or 4 part fractures of the upper part of the humerus. Material and Methods: Antegrade nailing with self stabilizing screws, by T2 nail, is used in 13 patients treated between January 2004 and December 2005. Average age is 81 years old. The medial insertion technique is used because of the greater tuberosity fracture. Clinical and radiological data were available for the 13 patients with a mean follow up of 19 months. Functional outcome is assessed using the Visual Analog Scale (VAS) and the Constant Score. Results: At last follow up, most of the patients are satisfied with their operation with a mean VAS of 2.46 and a mean Constant Score of 64.7. Mean antepulsion was 148° while mean abduction was 136°. No infection was reported. There are 4 cases of greater tuberosity necrosis without influence on the rotator cuff muscles. One case of head necrosis is signaled. Discussion: Complex fractures of the proximal humerus remain a challenge for the orthopedic surgeons. To date, there is non agreement on the most appropriate osteosynthesis method and the results of shoulder arthroplasty or proximal plating remain controversial. The T2 nail appears to be a simple and reproducible method of achieving reduction, stability and early mobilization. It is an attractive alternative to shoulder prosthesis or proximal plating in trauma victims with complex displaced fractures

Although few published papers assess the results of revision total shoulder replacement for painful hemi-arthroplasty with a functional rotator cuff, surgical outcome is accepted as being poor. Our experience suggests that results are poor if a well-fixed humeral stem is revised to correct version, and if a non-functional rotator cuff is not alternatively managed. We identified fifteen patients with painful hemi-arthroplasty and a suspected functional rotator cuff that underwent revision total shoulder replacement at Wrightington hospital over a ten year period. The aetiology comprised osteoarthritis (seven), inflammatory arthritis (five), trauma (two) and avascular necrosis (one). The average time interval to revision surgery was 44.5 months. Humeral head size was up-sized in two and down-sized in seven cases at revision surgery. Three cases underwent iliac crest autografting for glenoid deficiency. Four cases underwent humeral stem revision for incorrect version. The average surgical time for primary total shoulder replacement at Wrightington hospital is 80 minutes while the average time for these revision total shoulder replacements was 105 minutes. Four patients had an unsatisfactory outcome according to Neer’s criteria due to an intra-operative greater tuberosity fracture (one), an intra-operative humeral shaft fracture (one) and a non-functional rotator cuff (two), one of which was revised to an extended head prosthesis with good outcome. Surgical time for revision and primary total shoulder replacement did not differ significantly if humeral stem revision or glenoid augmentation was not indicated. Oversized humeral head components may cause pain due to overstuffing the joint and soft tissues. Revision total shoulder replacement for hemi-arthroplasty with incorrect prosthetic version cannot guarantee an improved outcome. Significant glenoid deficiencies can be effectively managed by iliac crest bone grafting at revision total shoulder replacement. Rotator cuff deficient patients should be managed with alternative prostheses

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

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 glenoid were the most frequent osteotendinous injuries. The axillary nerve was most frequently injured neurological structure. We were unable to elicit any significant statistical differences between bifocal and trifocal injuries with regards to patient demographics. However, when compared with unifocal injuries, bifocal or trifocal injuries were more likely to occur in older, female patients resulting from low energy falls (p<0.05). Conclusions. We present the largest series reporting the epidemiology of injury patterns related to traumatic anterior shoulder dislocation. Increased understanding and awareness of these injuries among clinicians will improve diagnosis and facilitate appropriate treatment

Aim: Traumatic shoulder dislocation in patients older than 50 years is an unusual injury with specific anatomic lesions and different treatment considerations than these encountered in younger patients. We present our experience in treating such kind of injuries. Patients-methods: Between January December 2002 9 patients-4 males, 5 females – with ages ranging between 50–72 years (mean age 64 y.), have been treated in our department suffering from first traumatic shoulder dislocation. Rehabilitation program and overall recovery progress was observed in an outpatient basis while postoperative outcome was evaluated using ASES and UCLA rating scores. Results: In 4 patients rotator cuff tear was found and reconstructed by suturing the lesion. One (1) of these patients, who had a coexisted bony Bankart lesion, presented 1 ½ month postoperative with recurrence of dislocation. Bony Bankart lesion prevented reduction in 2 patients and was reconstructed using open stabilization in one and arthroscopic to the other. HAGL lesion was detected in another patient and treated with open reduction and shoulder stabilization. Finally 2 patients with shoulder dislocation and coexisted greater tuberosity fracture were treated with closed reduction. Conclusions: Ttraumatic shoulder dislocation in patients older than 50 years consists a distinct entity which if inadequately treated leaves the shoulder with severe functional impairment. Recurrent shoulder dislocation is an unusual complication in such patients but on the other hand rotator cuff tears and glenoid bony lesions are frequently encountered necessitating treatment. Postoperative patients should be examined in small intervals with a high degree of suspicion for the above mentioned coexisted lesions

To identify any shoulder joint pathology on MRI of young patients (< 35 yrs) with a single simple antero- inferior dislocation of the shoulder at minimum 5-year follow-up. Patients aged 16–35 years with a single antero-inferior shoulder dislocation with a minimum 5-year (range5–9 yrs) follow-up were identified. A history of recurrent dislocation or surgery excluded patients from study. Ethical approval was obtained and identified patients were asked to volunteer for clinical review and have an MRI scan. Shoulders were clinically examined, noting specifically any signs/symptoms of rotator cuff pathology or instability. All shoulders were imaged with a 1.5 Tesla open MRI scan to assess any pathology. In a 5-year period (1994–1998), 349 patients sustained an antero-inferior dislocation. 251 were in patients aged 35 years or less. 136 of these were excluded either due to recurrent dislocations. 62 patients were lost to follow-up of 53 eligible patients 7 could attend for study. Only one patient had a positive anterior apprehension sign but he did not have any symptoms of instability in his daily activities or sport. The only abnormality demonstrated on MRI was of a united greater tuberosity fracture in one shoulder. The glenolabral and bicipitolabral complexes were normal in all shoulders imaged. Bankart lesions, both bony and labral, are known to be associated with recurrent anterior shoulder dislocations.This study has shown no shoulder joint pathology on MRI at minimum 5-year follow-up in young patients who have sustained a single antero-inferior shoulder dislocation, confirming that labral pathology seems to be important in recurrent dislocations. Further study to image more patients is underway. These results indicate that acute imaging of dislocated shoulders may be useful to help predict young patients who are unlikely to re-dislocate and thus unlikely to require surgery

Introduction: Fracture of the proximal humerus are challenging for diagnosis and treatment. The vast majority of these fracture associated with osteoporosis in elderly. Decision making for the treatment must include all arguments of fracture type, physical demands and rehabilitation cooperation of patients. This is particularly crucial in proximal humerus fracture. Results of surgery including hemiarthroplasty are difficult to predict and many times type of surgical treatment can be determined intra-operative or at least after closed manipulation attempt. Material and methods: Between September 1998 to September 2000, 68 patients underwent surgery for proximal humerus fracture. Patients who underwent hemiarthroplasty were not included in this study. Diagnosis of the fracture was based on Neer classification system and was aided by CT scan. Type of surgery was made finally after closed manipulation attempt under anesthesia. Patients were consented for closed manipulation, open reduction and internal fixation or hemiarthroplasty. Data was collected retrospectively from outpatients notes. 32 males and 36 females, age 40–88 (mean: 62), underwent closed manipulation and pinning (30), ORIF included pinning and PDS suture (32) and ORIF included PDS suture only (6). Fracture type distributed as follows: 2 parts surgical neck – 9, 2 parts GT – 6, 3 parts – 29, fracture dislocations – 6, 4 parts – 12, impacted valgus fracture 6. Four threaded pins were inserted retrograde and trimmed under the skin. Two antegrade pins were left out of the skin and banded to prevent migration to the axilla. Patients were immobilized in shoulder immobilizer for 6 weeks when pins were removed in outpatient clinic. Control X-ray was taken at 2, 4, 6, 12 weeks. If fracture was noted to be unstable, X-ray was taken every week up to 4 weeks. In case of any deterioration after 12 weeks X-ray was taken to detect signs of AVN. Rehabilitation program commenced after clinical union with passive and assisted active for 4 weeks followed by active mobilization. Follow-up ranged from 10–34 months (mean: 22) and range of motion with X-ray description were documented. Results: All fractures but one were united, fracture position was noted in 31 patients as normal in 46 (68%), head-shaft in extension in 8 (11.7%), varus head – 7 (10%), valgus head – 1 (1.4%), prominent GT – 4 (6%), prominent LT – 3 (4.4%), complete displacement – 2 (2.8%), dislocated – 1 (1.4%). Mean range of motion for all groups was: Elevation – 144 (60–180), External Rotation – 54.6 (−10–80), Internal Rotation – L1 (Throchanter – T8). Statistical analysis for fracture groups showed best results for impacted valgus and greater tuberosity fracture after open reduction and worst results were noted for 4 parts fractures and fracture dislocation. Although the study was not randomized there was no significant difference between the group of closed pinning and open surgery. Complications: Six patients had revision surgery during the early follow up due to fixation failure. In one case repinning was performed, in 2 cases closed pinning transformed to open surgery and suture of GT, in one case osteotomy and re-insertion of LT was needed, one case complete lost of fixation ended in hemiarthroplasty and one case of fracture dislocation failed to closed and open surgery and need bone block (Laterget) to prevent re-dislocation. AVN was noted in 5 cases – 2 partial and 3 complete (3% and 4.4%, respectively). Pin tract infection occurred in the 6 of prominent antegrade pins and resolved after early removal of these pins without the retrograde pins. G-H arthrosis was noted in one case after 2 years. Conclusions: Surgical treatment of proximal humerus fracture and attempt to preserve the humeral head is alternative to conservative treatment or hemiarthroplasty from the other hand. High surgical are demanded and fixation cannot be guaranteed due to minimal bone stock for fixation. Partial loss of fixation still leave better position and reasonable functional results. Further attention is needed to the lesser tuberosity which could be seen better under fluoroscopy under anesthesia
