Functional and radiological outcome of proximal femoral locking compression plates in the treatment of unstable trochanteric fractures

Background Split-depression fractures to the lateral tibial plateau (AO41B3) often feature severe joint surface destructions. Precontoured locking compression plates (LCPs) are designed for optimum support of the reduced joint surface and have especially been emphasized in reduced bone quality. A lack of evidence still inhibits their broad utilization in elderly patients. Thus, aim of the present study was to investigate the implant-specific radiological outcomes of AO41B3-fractures in young versus elderly patients. Methods The hospital’s database was screened for isolated AO41B3-factures, open reduction and internal fixation (ORIF), and radiological follow-up ≥12 months. CT-scans, radiographs, and patients’ records were analyzed. Patients were attributed as young (18–49) or elderly (≥50 years). Additional subgrouping was carried out into precontoured LCP and conventional implants. The Rasmussen Radiological Score (RRS) after 12 months was set as primary outcome parameter. The RRS postoperatively and the medial proximal tibial angle (MPTA) postoperatively and after 12 months were secondary outcome parameters. Results Fifty nine consecutive patients were included (26 young, 38.2 ± 7.8 years; 33 elderly, 61.3 ± 9.4 years). There were no significant differences regarding mean size and depression depth of the lateral joint surface fragments. Prior to implant-specific subgrouping, the radiological outcome measures revealed no significant differences between young (RRS = 7.7 ± 1.7; MPTA = 90.3 ± 2.3°) and elderly (RRS = 7.2 ± 1.7; MPTA = 90.5 ± 3.3°). After implant-specific subgrouping, the radiological outcome revealed significantly impaired results in young patients with conventional implants (RRS(C) = 6.9 ± 1.6, RRS(LCP) = 8.5 ± 1.5, P = .015; MPTA(C) = 91.5 ± 1.9°, MPTA(LCP) = 89.1 ± 2.1°, P = .01). The effect was even more pronounced in elderly patients, with highly significant deterioration of the radiological outcome measures for conventional implants compared to precontoured LCP (RRS(C) = 5.7 ± 1.6, RRS(LCP) = 8.2 ± .8, P < .001; MPTA(C) = 92.6 ± 4.2°, MPTA(LCP) = 89.2 ± 1.4°, P = .002). Conclusion Utilizing precontoured LCP in the treatment of AO41B3-fractures is associated with improved radiological outcomes. This effect is significant in young but even more pronounced in elderly patients. Consequently, precontoured LCP should closely be considered in any AO41B3-fracture, but especially in elderly patients.

Objectives: To determine the clinical and radiological outcome of proximal femur shaft fractures in school going children treated with locking compression plates (LCP). Methods: This descriptive study was conducted in Orthopaedic Division Lady Ready Reading Hospital Peshawar from 25th June 2018 to 25th September 2020. Children of either gender and age 6 to 12 years old with subtrochanteric and proximal one third femur factures fulfilling the inclusion criteria were enrolled in this study. Open reduction and internal fixation with 4.5 mm narrow locking compression plates (LCP) were done in all. Post operative clinical outcome was evaluated by using Flynn scoring system and graded as excellent, satisfactory and poo results. Radiological assessment of fracture union was done through anteroposterior (AP) and lateral X-ray radiographs. Results: A total of 60 children with mean age 9.01±1.61 SD (range 6 to 12 years) were included in our study. Oblique fractures were present in 23(38.3%) children, spiral in 20(33.3%), transverse in 11(18.3%) and comminuted in 6 (10%) children. The radiological union time was 13.3±1.2 weeks (range 9.4 to 18 weeks). Majority (88.3%, n=53) of children had excellent clinical outcome according to Flynn’s scoring system while satisfactory outcome was noted in 7(11.6%) children. No cases of delayed union, mal union, nonunion and implant failure was reported. Conclusion: The results of our study indicated that proximal femoral shaft fractures in school going children treated with locking compression plates had excellent clinical and radiological outcome. We therefore recommend locking compression plate as the implant of choice to fix proximal femoral shaft fractures in school going children. doi: https://doi.org/10.12669/pjms.37.5.3938 How to cite this:Shah FA, Ali MA, Naeemullah.
