Musculoskeletal injuries following seizures have a high morbidity and mortality. These injuries are often missed and the diagnosis is delayed due to a lack of clinical suspicion and appropriate investigations.We report a case of 72 years old male with simultaneous bilateral central acetabular fracture dislocation and bilateral posterior shoulder fracture dislocation secondary to an epileptic seizure. Present study high- lights the significance of clinical suspicion and clinico-radiological evaluation for diagnosis of a rare injury following episode of seizures. Simultaneous fracture dislocation of all four limbs treated with a holistic approach can lead to a good functional recovery. Surgical management with open reduction and internal fixation is preferred and replacement arthroplasty should be reserved for cases with implant failure and elderly patients.

OBJECTIVE
This study aimed to investigate the epidemiological characteristics and treatment options of proximal humerus fractures at a level one trauma center and to compare our data with the current literature.
METHODS
A retrospective review was conducted on all patients diagnosed and treated for proximal humerus fractures at Hamad General Hospital, a level one trauma center, between January 2018 and December 2019. Age, gender, mechanism of injury, fracture classification, mode of treatment, implant type, length of hospital stay, associated injuries and complications were analyzed.
RESULTS
A total of 190 patients with a mean age of 52.4 years were included; 56.8% were males. The incidence of proximal humerus fracture was 4.1/100,000 per year. Falling from a standing height was the most common cause of injury (50.5%). Additionally, Neer's two-part fracture was found to be the most common type (n = 132, 69%). Forty-one patients (21.3%) had other associated injuries. Most fractures were treated nonoperatively with an arm sling (n = 138, 72.6%).
CONCLUSION
In summary, the incidence of proximal humerus fractures during the two-year study period was found to be 4.1 per 100,000 persons per year. Our results showed a lower incidence of proximal humerus fractures with a predominance of males and younger patients in Qatar's population compared to females and older patients in the developed countries. Our results may contribute to the development of effective strategies for preventing and treating proximal humerus fractures, and can provide important data for further high-level clinical research.

INTRODUCTION
Proximal humerus fractures are common injuries of the elderly. Different treatment options, depending on fracture complexity and stability, have been recommended in the literature. Particularly for varus displaced fractures with a lack of medial support, and patients suffering from osteoporosis, structural allografts can be used to enhance the stability of the construct. An individually shaped allograft has been suggested in the literature and investigated in a clinical setting. However, biomechanical properties have yet to be evaluated.
MATERIALS AND METHODS
Twenty-four fresh-frozen humeri and 12 femoral heads were obtained, and an unstable three-part fracture of the humeral head was simulated. Fracture fixation was achieved by using a locking plate in both groups. In the test group, a mushroom-shaped allograft was tailored out of a femoral head to individually fit the void inside the humeral head. Specimens were fitted with a 3D motion analysis system and cyclically loaded with a stepwise increasing load magnitude in a varus-valgus bending test until failure or up to a maximum of 10,000 load cycles.
RESULTS
The mushroom group reached a significantly higher number of load cycles (8342; SD 1,902; CI 7133-9550) compared to the control group (3475; SD 1488; CI 2530-4420; p < 0.001). Additionally, the test group showed significantly higher stiffness values concerning all observational points (p < 0.001).
CONCLUSION
This mushroom-shaped allograft in combination with a locking plate significantly increased load to failure as well as stiffness of the construct when exposed to varus-valgus bending forces. Therefore, it might be a viable option for surgical treatment of unstable and varus displaced proximal humerus fractures to superiorly prevent loss of reduction and varus collapse.

OBJECTIVE
To report the clinical and radiological outcomes of arthroscopically assisted surgery for combination of glenoid and greater tuberosity fractures after traumatic shoulder dislocation.
METHODS
From December 2013 to December 2018, patients with concomitant fracture of the greater tuberosity and glenoid who underwent arthroscopically assisted surgery were retrospectively reviewed. Fifteen patients were included. Preoperative computed tomography (CT) scans with 3D reconstruction were performed to evaluate the fracture configuration and associated fractures. All patients underwent arthroscopically assisted surgery under general anesthesia with brachial plexus anesthesia in the lateral position. Under the arthroscopic approach, a comprehensive inspection of the joints was firstly conducted to examine the injury of bones and other tissues. With arthroscopy support, closed reduction and internal fixation of both fractures were performed with suture anchors, with or without additional cannulated screws. At the same time, other injuries were also repaired under the arthroscope. Patients were followed up (6 weeks,8 weeks,3 months,6 months,1 year after surgery) regularly for at least 1 year. At the follow-up, clinical outcomes (Constant score, ASES score, range of motion, and VAS score) and radiological outcomes were analyzed.
RESULTS
Of the 15 patients, there are seven cases of men, eight cases of women; aged 22-66 years, with an average age of 48 years; left shoulder for five cases, 10 cases of the right shoulder. The injury mechanisms were: a simple fall (n = 9), an epileptic seizure (n = 1), a high fall injury (n = 2), and a traffic accident (n = 3). Of the 15 cases of glenoid fracture, 11 cases were type Ia and four cases were type II according to the Ideberg Classification System. The mean size of the glenoid fracture fragment was 28.4% (range, 8.7%-47.2%). According to the Mutch classification system, the fractures of the greater tuberosity were divided into: five cases of avulsion, one case of compression, and nine cases of split. Average time of follow-up was 38.2 months (range, 12-70 months), and one case was lost to follow-up. With fractures healing well, almost all patients had a good joint function. At the final follow-up, mean anterior flexion was 157°; mean external rotation was 40°; mean internal rotation was T level; the mean Constant-Murley score was 94.6 points (range, 70-100 points); the mean ASES score was 94.6 points (range, 79-100 points); and the mean VAS score was 0.4 points (range, 0-2 points). No recurrent instability or re-dislocation occurred. No patient had revision surgery.
CONCLUSION
Arthroscopic management of glenoid and greater tuberosity bipolar fractures was useful and effective with minimal injury, and it achieved satisfactory clinical and radiological outcomes at a mean follow-up time of more than 3 years.

PURPOSE
Radiographic parameters which correlate with poor clinical outcome after proximal humeral fractures could be helpful indicators to answer the question which patients should be followed up closer. Moreover, during surgery, radiographic parameters correlating with unfavourable outcome should be avoided. The primary aim of the study was to compare radiographic measurements between the injured and the contralateral, uninjured shoulder. The secondary aim was to correlate these radiographic parameters with post-operative shoulder function.
METHODS
Fifty-eight patients (age: 55.6 ± 14.4 years, age at surgery) following angular stable plate fixation of a proximal humeral fracture (2-part fractures according to Neer: 24, 3-part: 25, 4-part: 9) were included in this retrospective cohort study. All patients were followed up at least six years (7.9 ± 1.4 after surgical intervention). During follow-up examination, the Constant score (CS) was assessed, and radiographs of both shoulders were taken. Radiographs were analyzed regarding lateral humeral offset, distance between tuberculum and head apex, head diameter, head height, perpendicular height, perpendicular center, vertical height, and angles between head and humeral shaft (CCD and HSA). These parameters were compared between the injured and uninjured shoulder. The cohort was divided in two groups: patients with a CS category of excellent/good and satisfying/worse. Both groups were tested regarding differences of demographic and radiographic parameters.
RESULTS
The distance between tuberculum and head apex (2.6 ± 3.4 mm vs. 4.3 ± 2.1 mm; p = 0.0017), the CCD (123.1 ± 12.9° vs. 130.1 ± 7.3°; p = 0.0005), and the HSA (33.1 ± 12.8° vs. 40.1 ± 7.3°; p = 0.0066) were significantly smaller on the treated shoulder compared to the uninjured side. Patients reached a Constant score of 80.2 ± 17.4 (95% CI 75.6-84.8) points. Regarding outcome categories of the Constant score, 46 patients had a good to excellent outcome, and 12 patients had a satisfying or bad outcome. The comparison of these groups revealed that patients with inferior outcome in the long-term follow-up were older, female, had a more complex fracture type (AO classification), smaller lateral humeral offset, smaller head diameter and height, lower perpendicular height, and lower CCD and HSA angles.
CONCLUSION
If the abovementioned parameters cannot be restored sufficiently during surgery, (reversed) shoulder arthroplasty might be a better solution to reach good post-operative outcome. Moreover, patients presenting these radiographic characteristics in the follow-up, older patients, and patients with a more complex fracture type should be followed up closer to possibly prevent poor shoulder function.

Functional outcomes before and after implant removal in patients with posttraumatic shoulder stiffness and healed proximal humerus fractures: does implant material (PEEK vs. titanium) have an impact? - a pilot study.
BACKGROUND
Posttraumatic shoulder stiffness remains a problem after proximal humerus fracture (PHF) despite good healing rates. The aim of this pilot study was to determine whether the implant material and overlying soft tissue have an effect on shoulder range of motion (ROM) before and after implant removal (IR).
METHODS
16 patients (mean age 55.2 ± 15.3 (SD) years; 62.5% female) were included who underwent operative treatment with locking plates of either carbon fiber reinforced Polyetheretherketone (PEEK) (PEEKPower® humeral fracture plate, Arthrex, Naples, Florida, USA, n = 8) or titanium alloy (Ti) (Philos®, DePuy Synthes, Johnson & Johnson Medical, Raynham, Massachusetts, USA, n = 8) for PHF. All patients presented with a limited ROM and persistent pain in everyday life after the fracture had healed, whereupon IR was indicated. ROM before and after IR were compared as well as the Constant Score (CS) and the CS compared to the contralateral shoulder (%CS) 1 year after IR.
RESULTS
In group PEEK, elevation was 116.3° ± 19.2° pre- and 129.4° ± 23.7° post-IR (p = 0.027). External rotation was 35.0° ± 7.6° pre- and 50.6° ± 21.8° post-IR (p = 0.041). External rotation with the humerus abducted 90° was 38.8° ± 18.1° pre- and 52.5° ± 25.5° post-IR (p = 0.024). In group Ti, elevation was 110.0° ± 34.6° pre- and 133.8° ± 31.1° post-IR (p = 0.011). External rotation with the humerus at rest was 33.8° ± 23.1° pre- and 48.8° ± 18.7° post-IR (p = 0.048). External rotation with the humerus abducted 90° was 40.0° ± 31.6° pre- and 52.5° ± 22.5° post-IR (p = 0.011). Comparison of the two implant materials showed no significant difference. The overall CS was 90.3 ± 8.8, the %CS was 91.8% ± 14.7%.
CONCLUSION
There was no significant difference in ROM, CS and %CS with respect to plate materials, although lower cell adhesion is reported for the hydrophobic PEEK. However, all patients showed improved functional outcomes after IR in this pilot study. In patients with shoulder stiffness following locked plating for PHF, implants should be removed and open arthrolysis should be performed, independently from the hardware material.

OBJECTIVE
In complicated Neer three- and four-part proximal humerus fracture (PHF), greater tuberosity (GT) fragments are often comminuted, and the currently widely used locking plate may not fix GT fragments effectively. A further understanding of morphological characteristics of the GT fragments may help explore new fixation devices. This study aimed to determine the fracture line morphology of the GT fragment of Neer three- or four-part PHF and analyze the location relationship between the locking plate and the GT fragment.
METHODS
Seventy-one three-dimensional computed tomography scans of Neer three- and four-part PHF were retrospectively reviewed between January 2014 and June 2019. Fracture fragments were reconstructed and virtually reduced in the Mimics software, and fracture lines of GT fragments were depicted on a humerus template in the 3-matic software and then were superimposed altogether. The common sites of the GT fracture were identified, and the location relationship between the locking plate and GT fragments was analyzed in a computer-simulated scenario.
RESULTS
The fracture line morphology of GT fragments was similar between Neer three- and four-part PHF. The overall morphology of GT fragments was in a fan shape, which could be summarized as anterior, superior, posterior, and middle lines. Of these, we identified 51 split and 29 avulsion type GT fragments based on the Mutch classification, and they could occur simultaneously in a PHF. The overall morphology of split type fragments was in a fan shape, and avulsion type fragments showed a quite distinguishable distribution pattern. A GT fragment could be classified as anterior-split, posterior-split, complete-split, anterior -avulsion, and posterior-avulsion type based on its morphology and location. The median percentage of fragment area covered by the plate was 32.3% in all of the fragments, and it was 69.4%, 23.0%, 37.2%, 21.8%, 0.0% in anterior-split, posterior-split, complete-split, anterior-avulsion, and posterior-avulsion type GT fragments. We defined the posterior-split, anterior-avulsion, and posterior-avulsion type GT fragments as the risky GT fragments, and they occurred in 43 (60.6%) Neer three- and four-part PHFs.
CONCLUSION
The fracture line morphology of GT fragments of Neer three- and four-part PHF was in a fan shape. GT fragments could be classified based on their location and morphology. The extent of GT fragment coverage provided by the locking plate differed in various fragment types, and we identified the anterior-avulsion, posterior-avulsion, and posterior-split type fragments as the risky GT fragments with a high incidence rate in Neer three- and four-part PHFs.

BACKGROUND
The surgical treatment of displaced proximal humeral fractures is commonly affected by implant-related complications. We evaluated the functional and radiographic results of transosseous suture fixation in a series of displaced proximal humeral fractures (PHF).
METHODS
Sixty-four patients were retrospectively classified by age, sex, and the Neer fracture classification. Two-part greater tuberosity (2pGT) displaced fractures and 3-part (varus and valgus) and 4-part valgus impacted fractures were managed with fragment reduction and transosseous suture fixation. Patients with minimum follow-up of 24 months and assessed with the Constant-Murley score (CMS) were included. Radiological and medical complications, as well as reinterventions were also recorded.
RESULTS
Forty-six patients with a mean follow-up of 58 (24-132) and a mean age of 58 years old were analyzed. Patients with 2pGT (n = 10) fractures had a CMS of 76 points (59-89); patients with 3-part fractures (n = 22) had a score of 67 points (13-91); and those with 4-part fractures (n = 14) had a score of 64 (24-76) points. The overall complication rate was 6 out of 46, and 4 patients required reintervention for different reasons. Patients presenting with 3-part varus fractures had significantly lower functional outcomes scores (p = 0.007). Humeral head osteonecrosis was present in 9 patients and significantly affected the functional outcomes (p < 0.05). However, only three out of nine patients with osteonecrosis required subsequent surgery at the indicated follow-up.
CONCLUSIONS
The fracture reduction and transosseous fixation technique represents a safe technique with low complication and reintervention rates. The presence of humeral head necrosis did not lead to subsequent surgical intervention because no hardware had protruded.
