Bilateral anterior shoulder dislocation with bilateral fractures of the greater tuberosity: A case report

Bilateral anterior dislocation of the shoulders with fractures of both greater tuberosities is very rare. A 76-year-old woman sustained a bilateral anterior dislocation of her shoulders with fractures of the greater tuberosity on both sides after a fall on stairs. Her arms were abducted and externally rotated. Radiological examination revealed the bilateral anterior dislocation and also the bilateral fractures of the greater tuberosity. Prompt closed reduction followed by a 3 weeks immobilization and subsequent rehabilitation allows a good outcome. Results at one-year follow-up were satisfactory with normal range of motion and no redislocations occurring. To our knowledge, this is the first reported case of bilateral anterior shoulder dislocation associated with fractures of both greater tuberosities in elderly woman.     

Knee Instability Before and After High Tibial Osteotomy

Knee joints were examined by three-point measurement (Edholm et al. 1976, 1977). the instability in arthrotic joints did not differ significantly from that in normal knees, but the varus/valgus deviation as measured by the three-point technique differed significantly from that in normal knees. After high tibial osteotomy for varus malalignment the instability increased significantly. An increase of more than 2° was associated with significantly poorer subjective results of operation. the findings indicate that shortening of the lateral stabilizing structures of the knee joint should be carried out in connection with high tibial osteotomy for varus malalignment. No upper limit of preoperative instability consistent with a good result of operation was established.

Knee Instability: An Orthoradiographic Study

An orthoradiographic method for preoperative assessment of mediolateral instability and varus/valgus deviation in gonarthrosis is presented. a special definition of the varus/valgus deviation is given. The examination technique has been tested on 15 young, healthy subjects with no clinical signs or symptoms in their knee joints. to test the accuracy of the method, seven of the subjects were re-examined at a later date.

Evaluation of the relationship between scapula morphology and anterior shoulder dislocation accompanying greater tuberosity fracture

IntroductıonIt is estimated that 5–30% of traumatic anterior shoulder dislocations are accompanied by greater tuberosity fracture (GTF), and the pathomechanism of these fractures is not yet clear. Our hypothesis is to examine the relationship between the scapula morphology and anterior shoulder dislocation (ASD) accompanying GTF.Materıals and methodsThe patients were divided into two groups according to the accompanying GTF. 40 patients with isolated traumatic ASD and 31 patients with accompanying GTF were included in the study. Critical shoulder angle (CSA), glenoid inclination (GI), acromial index (AI) and greater tuberosity angle (GTA) values were measured in two sessions by two independent observers in the standard antero-posterior radiographs of the patients in both groups.ResultsThe mean CSA was 40.82°±3.19° and 35.49°±2.19° in accompanying GTF group and the isolated ASD group, respectively. The mean CSA was significantly higher in accompanying GTF group than isolated ASD group(P<0.001). The GI was significantly higher in the isolated ASD than in accompanying GTF group (P = 0.001). The mean GI was 18.7°±6.85° and 10.45°±4.87° in accompanying GTF group and the isolated ASD, respectively. Cut-off value of CSA and GI was 38° (88.2% sensitivity,88.9% specificity) and 14.5° (70.6% sensitivity and 72.2% specificity), respectively. There was no significant difference regarding the mean GTA and AI values between GTF group and the isolated ASD group (P = 0.98, P = 0.63).ConclusıonsIncreased CSA and GI values are associated with traumatic anterior shoulder dislocation accompanied by greater tuberosity fracture.     

Anterior shoulder dislocation and concomitant fracture of the greater tuberosity

Background

Recurrence rates after primary traumatic shoulder dislocation are distinctly high. We hypothesized that concomitant isolated fractures of the greater tuberosity are associated with low rates of persistent instability but decreased range of motion.

Methods

Between 2007 and 2013, 66 consecutive shoulders in 64 patients were treated for primary shoulder dislocation combined with an isolated fracture of the greater tuberosity with either a nonsurgical (48 shoulders, 72.7%) or surgical (18 shoulders, 27.3%) treatment approach. In all, 55 cases (83.3%) were available for clinical follow-up examination after an average of 59.0?± 20.7 months (range: 25–96 months) and of these, 48 (72.7%) patients consented to radiological evaluation to determine healing and position of the greater tuberosity.

Results

The mean range of motion of the affected shoulder was significantly decreased by 9° of elevation (p?=?0.016), 11° of abduction (p?=?0.048), 9° of external rotation in 0° of abduction (p?=?0.005), and 10° of external rotation in 90° of abduction (p?=?0.001), compared with the unaffected shoulder. The mean WOSI score was 373?± 486 points, the mean Constant and Murley score was 75.1?± 19.4 points, and the mean Rowe score was 83?± 20 points. Three cases (5.5%) of re-dislocation were reported among the cohort, all of them were due to a relevant trauma. Radiological evaluation revealed anatomically healed fragments in 31 shoulders (65%), dislocation of the fragment in ten shoulders (21%), impaction into the humeral head in four shoulders (8%), and absorption in three shoulders (6%).

Conclusion

A concomitant isolated fracture of the greater tuberosity leads to low recurrence rates along with a significant decrease in range of motion after primary traumatic anterior shoulder dislocation.

     

Coracoid pseudarthrosis caused by anterior shoulder dislocation with concomitant coracoid fracture

Fractures of the coracoid process are rare and represent only 2-5% of all fractures of the scapula. The most frequent cause of a coracoid fracture is direct trauma, but indirect trauma may also lead to a fracture of this kind. Avulsion injuries as part of an acromioclavicular dislocation are the most frequent forms of trauma. For the rare cases of an anterior shoulder dislocation with concomitant coracoid fracture, two different mechanism are discussed. One cause of the coracoid fracture could be direct impact of the dislocated head of the humerus on the coracoid process, another may be the occurrence of a sudden strong pull of the muscles inserting at the coracoid process during shoulder dislocation.In the majority of cases, conservative treatment with six weeks of immobilization is appropriate. If a pseudarthrosis occurs and there is persistent pain, we recommend the operative fixation of the distal coracoid fragment by insertion of cancellous bone graft taken from the iliac crest and stabilization with a cannulated AO titanium small fragment screw and PDS cord.     

High Tibial Osteotomy with Overcorrection of Varus Malalignment in Medial Gonarthrosis

Seventy-eight knee joints with varus malalignment were examined pre-operatively using three-point measurement. Operation was performed with or without 5° overcorrection of the varus deformity using random selection. the overcorrection group showed significantly better results than the normal-correction group.     

The high tibial osteotomy,open versus closed wedge,a comparison of methods in 108 patients

Introduction: One hundred and eight patients with varus gonarthrosis were treated with high tibial osteotomy (HTO) in 2001. Fifty one patients received an open wedge osteotomy by using the ‘Puddu’ plate and 57 patients received a Coventry-type closing wedge osteotomy. For both groups the follow-up examination period was 22.5 months (253–1009 days). Material and Methods: To evaluate the study, radiological and subjective criteria as well as the Lysholm and the Tegner Activity Score were used. Altogether 84 % of the patients were included in the follow-up examination study. Results: In both groups a significant improvement of both scores were achieved. Both methods obtained safe and reproducible results for the correction considering the different operation techniques. There were no differences in outcome between the two methods. Satisfactory results were also achieved for early arthrosis of the femoropatellar and the lateral compartment. Conclusion: Open and closed wedge HTOs obtain significant improvement in patients with medial osteoarthritis of the knee. Using the right technique is very important for good results. For stabilization of the medial ligament we recommend the open wedge osteotomy. The patient should be informed about the routine removal of the metal plate.     

Infraglenoid tubercle avulsion and greater tuberosity fracture resulting from traumatic glenohumeral anterior dislocation: a case report

Traumatic anterior shoulder dislocation can be associated with anteroinferior glenoid bone loss causing potential recurrent instability. We report on a 62-year-old man with a first-time traumatic anterior dislocation of the right shoulder, resulting in both an infraglenoid tubercle triceps avulsion fracture and a greater tuberosity fracture. After reduction, nonsurgical management was chosen. No inferior-oriented apprehension was noticed during follow-up, which might necessitate surgical treatment of the inferior glenoid rim. At latest follow-up, the patient had recovered his shoulder function. Avulsion fractures of the infraglenoid tubercle are uncommon lesions after an anterior shoulder dislocation and, without signs of instability, can be treated conservatively.
