Introduction: shoulder hemiarthroplasty is being relegated as a treatment for non-osteosynthetic proximal humerus fractures. Our objective is to analyze the functional results of patients treated with hemiarthroplasty for this reason in our hospital., Material and Methods: cross-sectional descriptive study that includes patients operated between February 2016 and November 2021; 24 patients, with an average follow-up of 44.6 months. Active joint balance, the Constant-Murley test, the DASH questionnaire and current pain (VAS) were collected. The radiographic parameters analyzed were the number of fracture fragments and the consolidation of the tuberosities., Results: a mean of 71.65 ± 13.75 was obtained in the Constant-Murley and 18.14% ± 13.92 in the DASH. For shoulder flexion, the mean was 108.75° ± 41.26; 104.5° ± 43.68 for abduction and 33° ± 14.73 for external rotation. About internal rotation, 60% of the patients reached the scapular plane. Average VAS was 1.25 ± 1.74. Consolidated tuberosities in 90.5%. There were no significant differences comparing the Constant-Murley test, DASH or rotations between both, over and under 65 years old group of patients. Those over 65 years of age obtained a mean flexion of 125.91° ± 26.82 whereas those under 87.78° ± 26.82 (p = 0.038). The mean abduction in those over 65 was 125.45 ± 28.94 vs 78.89 ± 46.29 in the young group (p = 0.012)., Conclusion: hemiarthroplasty provides quality of life with acceptable functionality and good pain control, therefore it should continue to be an alternative to consider in selected patients.

Introduction: The quality of reduction in proximal humerus fractures is valuable with radiographic criteria (Neck-shaft angle [NSA]; medial offset [MO]; distance head tuberosity [DHT] and subacromial space [SS]) that predict functionality. These criteria set for other implants are not described for the intramedullary nail., Material and Methods: Observational cohort study, retrospective, with patients 18 years, with osteosynthesis with intramedullary nail (2014 to 2017), evaluating demographic characteristics, severity of injury (Neer classification), progressive radiographic measurements and complications., Results: 84 cases with an average age of 65 ± 2 years and an average follow-up of 13.9 months were analyzed. By Neer rating 40.4% were grade II, 29.7% grade III and 29.7% grade IV. Consolidation in varus increases to 10.7% at the end of follow-up, with Neer III and IV patients. The 140° deformity is prevalent for Neer II (n = 15/34). 30.9% have a change of neck-shaft angle of 10°. Overall 86.9% has HTD changes 5 mm. Cases Neer III/IV 32% has alteration of SS 5 mm. The most common complication is avascular necrosis (AVN) with 44% of cases., Conclusions: Radiographic measurements have changes in long-term follow-up. Alterations in NSA ( 10o) and SS ( 5 mm) occur in higher proportion of Neer III/IV patients, according to the severity of the fracture, favoring vicious consolidations in varus or valgus and increased presence of AVN.

Introduction: The treatment of 3and 4 part proximal humeral fractures in elderly patients is still controversial. The frequent co-existence of poor quality bone and rotator cuff abnormalities in patients with multiple clinical conditions and with difficulties for physical rehabilitation leads to disappointing clinical results, even when the radiological images are acceptable., Objective: To evaluate the clinical, radiological, and functional results in patients over 65 years old with complex proximal humerus fractures treated with reverse shoulder arthroplasty., Material and Methods: A prospective review was carried out on 30 patients (26 women and 4 men) with proximal humeral fractures treated with reverse shoulder arthroplasty in our department. The mean age was 74.9 years (SD=6.3), and the mean follow-up was 34.5 months (SD=19.3)., Results: Clinical and functional results were acceptable, with a mean forward flexion of 124° and a mean external rotation of 13°. The mean abbreviated Constant abbreviated score was 49.1 (SD=14.1), 27 (SD=6.3) in the UCLA scale, and 32.2 (SD=19.2) in the QuickDASH questionnaire. The large majority (80%) of the patients are pain free, and they do not need medication to do daily activities. The complication rate was 13.3%., Conclusions: We consider that reverse shoulder arthroplasty is a valid option to treat 3and 4 part proximal humeral fractures in elderly patients. The surgical goals should include the anatomical reconstruction of the tuberosities, avoiding enlargement of the operated arm greater than 2cm., (Copyright © 2016 SECOT.

Objective: To evaluate the clinical results and analyse the complications of total reverse shoulder replacement performed in our centre over an 8 year period., Material and Method: A retrospective study was conducted on 50 patients (52 shoulders), with a mean age of 70.15 years (range 51 to 84 years) between December 2004 and December 2012, who received a total reverse shoulder replacement, all performed by the same surgeon. The results have been evaluated according to clinical data, radiography study, a satisfaction scale, and the Constant scale, with a minimum follow-up of 16 months. Five of the cases (9.62%) had been intervened due to fractures of the proximal end of the humerus, 6 cases (11.53%) as surgical consequence of a prosthesis revision, 10 cases (19.23%) due to fracture sequelae, and 30 cases (59.62%) were patients with arthropathy due to a massive fracture of the rotator cuff., Results: After a mean follow up of 35.78 months (range, 16-82), satisfactory clinical results were obtained in 80% of cases, with a mean preoperative Constant of 27.7 points, and reaching 67.1 points 12 months after the operation. On the visual analogue scale, 8.25 points were obtained before the surgery, which decreased to 2.25 points 12 months later. The complications rate was 15.38%, which were due to an intra-operative fracture (1.92%), deep infection (3.84%), instability (3.84%), and early mechanical loosening (3.84%). Scapular notching was observed in the radiographic study in 9 (17.3%) cases., Discussion and Conclusions: After the results obtained, it could be said that total reverse shoulder replacement achieved encouraging results in the short term for the treatment of glenohumeral arthrosis and massive tears of the rotary cuff. On analysing our series, it can be seen that the complications rate is much higher when it is used to treat fracture sequelae in which there is a loss of proximal humerus bone stock., (Copyright © 2014 SECOT.

Objective: An analysis was made on relationship between Notching and functional and radiographic parameters after treatment of acute proximal humeral fractures with reverse total shoulder arthroplasty., Methods: A retrospective evaluation was performed on 37 patients with acute proximal humeral fracture treated by reversed shoulder arthroplasty. The mean follow-up was 24 months. Range of motion, intraoperative and postoperative complications were recorded. Nerot's classification was used to evaluate Notching. Patient satisfaction was evaluated with the Constant Score (CS). Statistical analysis was performed to evaluate the relationship between Notching and glenosphere position, or functional outcomes., Results: Mean range of elevation, abduction, external and internal rotation were 106.22°, 104.46°, 46.08° and 40.27°, respectively. Mean CS was 63. Notching was present at 12 months in 29% of patients. Statistical analysis showed significance differences between age and CS, age and notching development, and tilt with notching. No statistical significance differences were found between elevation, abduction, internal and external rotation and CS either with scapular or glenosphere-neck angle., Conclusion: Reverse shoulder arthroplasty is a valuable option for acute humeral fractures in patients with osteoporosis and cuff-tear arthropathy. It leads to early pain relief and shoulder motion. Nevertheless, it is not exempt from complications, and long-term studies are needed to determine the importance of notching., (Copyright © 2014 SECOT. Published by Elsevier Espana.

The posterior instability of the shoulder only represents 4% of the shoulder instabilities. For the diagnosis, the antero-posterior, transtoracic and axilar radiographic projections are recommended. The inverted Hill-Sachs lesion is a fracture caused by compression of the antero-medial part of the humeral head during the posterior dislocation. Its treatment results, at least, controverted. Choosing the treatment of these lesions one of the main factors is the size of the defect in the humeral head. When it is smaller than 20%, the simple reduction usually is enough. Between 20-40%, we can opt for a transposition of the subescapular insertion to the bony defect (technique of MacLaughlin) or the anatomical reconstruction of the head by means of the fixation of an allograft. The transposition of the subescapular´s tendon carries a reduction of the internal rotation by medializing its insertion, for this reason, we opted for the anatomical reconstruction with allograft of femoral head that reestablishes the muscular balance. The shoulder artroplasty is elective when bony defects are bigger (>40-50 % of the articulation surface). We present the case of a 32 year-old patient, with the antecedent of convulsive crisis. Clinically he suffered intense pain with functional impotence and elastic limitation for the external rotation in left shoulder. The radiographic studies evidenced an instable posterior fracture-dislocation with inverted Hill-Sachs lesion associated that involved the 30% of the articular surface. The patient was surgically treated, opting for a reconstructive technique for humeral head. After six months, the range of motion is almost symmetrical with regard to the healthy shoulder, without any clinic of instability.
