Management of periprosthetic proximal femoral fracture of megaprosthesis with limited residual bone stock: A case report.
Article in International journal of surgery case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Periprosthetic fractures involving femoral megaprostheses are complex and challenging to manage due to limited residual bone stock available for fixation. In Indonesia, data on such complications are scarce, and surgical strategies often require adaptation based on resource availability. Case presentation: A 42-year-old man with a history of distal femoral megaprosthesis implantation for a giant cell tumor presented with right hip pain after a low-energy fall. Imaging showed a Vancouver type B3 periprosthetic fracture. The remaining proximal femoral bone stock measured only 7.5 cm, significantly limiting options for internal fixation due to poor surface area and compromised load distribution. Surgical management involved internal fixation using a trochanteric claw plate and cable wires. Dual 8 cm autologous fibular strut grafts were harvested and positioned anteriorly and posteriorly around the fracture site. Postoperative recovery was uneventful. At four-month follow-up, the patient demonstrated excellent progress, with no signs of infection, good range of motion, and absence of pain. Discussion: This case illustrates the viability of using a trochanteric claw plate and fibular strut grafts to treat periprosthetic fractures around a stable femoral megaprosthesis. The fracture likely occurred due to bone fragility at the cement-bone interface. The combination of mechanical fixation and biological grafting enabled early mobilization while preserving the existing implant. Conclusion: In resource-limited settings, this technique offers a promising limb-salvage strategy with favorable short-term outcomes. Further studies are needed to validate long-term effectiveness.
