• ABSTRACT
    • Background Proximal humerus fractures comprise nearly 4%-5% of all fracture types and nearly 25% of fracture humerus. These fractures are commonly seen in the elderly population (people aged 60 years or more). The best way to treat elderly people who have three- or four-part fractures of the proximal humerus is debatable, with many in favour of prosthetic humeral head replacements. This study aimed to assess the functional outcome of proximal humerus fractures managed with a proximal humerus locking plate and to investigate the incidence of complications in these patients. Methodology This retrospective study included 32 cases of proximal humerus fractures managed surgically at a tertiary care teaching hospital in Rajasthan between July 2016 to July 2022 with a proximal humerus internal locking system (PHILOS) plate. NEER scoring system was used to categorise the fractures. Functional assessment was done using Constant Murley's shoulder score. Constant Murley shoulder score was graded as failure (0-69 points), unsatisfactory (70-79), satisfactory (80-89), and excellent (90-100). Subjects having metastatic and pathological fractures; associated fractures in the ipsilateral limb; having major nerve injury and cases of open fracture were excluded from this study. Results The mean age was 54.5±6.4 years. Of the total 32 cases of proximal humerus fractures, 12 cases of two-part fractures received an excellent grade, compared to seven cases of three-part fractures. Three two-part fracture cases and two three-part fracture cases all received satisfactory grades. Excellent results (score > 89) were noticed in 62.5% (n = 20) of the instances, satisfactory results (scoring 80-89) in 21.87% (n=7), poor results (score 70-79) in 9.38% (n=3), and failure results (score 70) in 6.25% (n=2). In 65.6% of cases, follow-up showed no complications. Shoulder stiffness and malunion (9.38%) were the most frequent consequences, followed by avascular necrosis (6.25%). Conclusions Based on the findings of this retrospective study, it can be opined that PHILOS plaiting appears to be a secure option for proximal humerus fracture cases. It offers solid fixation, prompt mobilisation, and excellent functional outcomes as observed in this study. Additionally, very few post-operative complication rates again support our conclusion.
