One-stage surgical correction of Shepherd's crook deformity in fibrous dysplasia using fibular strut allograft augmentation: a retrospective case-series.

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
purposeShepherd's crook deformity is a characteristic complication of fibrous dysplasia (FD) of the femur, leading to coxa vara and mechanical instability. Two-stage surgical approaches involve initial valgus osteotomy followed by delayed intramedullary femoral stabilization, prolonged treatment, and increasing morbidity. This study evaluates a one-stage surgical correction that employs fibular strut allograft augmentation for both the femoral neck and shaft.
methodsA retrospective review was performed on 17 patients with Shepherd's crook deformity who underwent one-stage hip lag screw and side plate fixation with fibular strut allograft augmentation of the femoral neck and shaft between 2002 and 2022. Radiographic and clinical outcomes were assessed, including neck-shaft angle (NSA) restoration, fixation stability, graft incorporation, and functional improvement. The median follow-up of the patients was 96 months.
resultsThe mean preoperative NSA was 93° (SD: 13.5°), improving significantly to 130° (SD: 5°) at the latest follow-up (p < 0.001). Stable fixation was achieved in 16 of 17 patients, with one case of fixation failure. Fibular graft resorption was noted in six patients but did not compromise fixation. Clinically, postoperative pain, limping, and activity limitations improved substantially, though seven patients experienced persistent restrictions in outdoor activities. The average limb shortening was 3.5 cm before the operation and 0.9 cm at the end of the follow-up.
conclusionOne-stage correction of Shepherd's crook deformity using lag hip screw fixation and fibular strut allograft augmentation could be a viable alternative to staged procedures, though further studies are needed to confirm its efficacy and generalizability.
