“…Techniques for treating complex proximal humeral fractures vary and include fixations using tension bands, percutaneous pins, bone suture, T-plates, intramedullary nails, double tubular plates, hemiarthroplasty, Polarus nails, blade plates. [3][4][5][6][7][8] 17 PHILOS (proximal humeral internal locking system) is a recently developed system of ORIF, featuring: anatomically contoured shape, non-parallel locking head screws, high rigidity, Locking and LCP combination holes. Thus, theoretically less chance of screw pullout/loosening, better purchase in the humeral head and less secondary loss of reduction.…”

Background: Fracture of proximal humerus is the second most common fracture of the upper extremity, following distal forearm fractures. Aim of the present study was to evaluate the efficacy of proximal humerus internal locking system (PHILOS) plate fixation for proximal humerus fractures.Methods: Functional outcomes of 12 men and 18 women aged 22 to 78 (mean, 58) years who underwent PHILOS plate fixation for proximal humeral fractures were reviewed. Indications for surgery were 2 part (n=9), 3 part (n=14) or 4-part (n=7) closed proximal humeral fractures with angulation of more than 45 degrees or displacement of more than 1 cm. Functional outcomes and shoulder range of movement were assessed based on the Constant scoring system.Results: All patients will be followed up at monthly intervals for 6 months. During this period patient, will be motivated for physiotherapy and gradual normal use of the affected limb. Fracture union will be assessed clinically and radiologically. In our study of fracture proximal humerus union in most of the cases (24) occurring between 10-14 weeks. Range of union time was 8 to 18 weeks. one case of avascular necrosis of head occur in our case. In out of 30 cases excellent result in 7 cases, Good in16 cases Satisfactory in 5 cases and Poor in 2 cases were obtained.Conclusions: The PHILOS plate fixation is effective treatment for proximal humeral fractures particularly in osteoporotic bones.

“…15 The mean scores for 4-part and 3-and 4-part fractures with shaft involvement were 60 and 73, respectively. 15 Complications included avascular necrosis and collapse of the humeral head that led to nail protrusion and subacromial impingement (n=1) and loosening of the proximal screws necessitating removal (n=3). In another study of 20 patients with proximal humeral fractures treated with the Polarus nail, 14 achieved bone union.…”

Purpose. To report the outcomes of Polarus nail fixation for displaced proximal humeral fractures. Methods. Medical records of 19 men and 27 women aged 26 to 84 (mean, 63) years who underwent fixation using a standard Polarus nail (n=34) or Polarus plus nail with shaft extension (n=12) for proximal humeral fractures of 2 and 3 parts (n=34) and 2-part with extension to the shaft (n=12) were reviewed. Fracture union, neck shaft angle, and hardware complications were evaluated using radiographs. Outcomes were assessed using the Constant score, the visual analogue scale for pain, and subjective satisfaction. The range of motion, grip strength, and ability to return to work were also recorded. Results. The mean follow-up was 20 (range, 15-28) months. The mean humeral neck shaft angle was 137.2º. 44 (96%) patients achieved fracture union after a mean of 14 (range, 11-16) 2014;22(2):195-8 radial nerve palsy (n=2), impingement symptoms caused by the prominent metal work (n=10), and missing of the proximal screws in the nail (n=4). Respectively in patients aged <60 (n=15) and ≥60 years (n=31), the mean Constant scores were 79 and 67 (p=0.04). The mean pain score improved from 93 to 15.5 at 12 months. 16 patients were very satisfied, 22 were satisfied, and 8 were not satisfied with the outcome. Of the latter, 3 were aged <60 years and 5 were aged ≥60 years. Conclusion. Polarus nail fixation for displaced proximal humeral fractures achieved good fracture union and satisfactory functional outcome, particularly in younger patients and those in active employment, but elderly dependent patients tended to have poor functional results. The rates of minor hardware problems and non-union in 3-part fractures were relatively high.

“…Nail fixation of the humerus is not new [7,9,11] but is experiencing a renaissance, partly due to the availability of fixed-angle implants and optimized targeting devices for nail locking [1,5,6,8,10]. The introduction of several proximal locking options at various angles to each other, which permit fixed-angle and nongliding nail locking, has increased the stability of screw fixation in the osteoporotic humeral head.…”

From December 2000 to spring 2004, 133 patients (average age: 74.9 years) with 137 unstable proximal humeral fractures were treated surgically. 97 patients with 99 operated shoulders were followed up for at least 7 months. The patients' average age at follow-up was 74.9 +/- 13.6 years (20-102 years). A Constant Score of 60.0 +/- 16.8 points was achieved and 84.8 +/- 19.4% and 84.0 +/- 15.5% on the age- and gender-related as well as side-related Constant Scores.
