Nerve palsy following total hip arthroplasty using trochanteric osteotomy and proximal femoral shortening in Crowe Type 4 developmental dysplasia of the hip: a prospective cohort study.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionTotal hip arthroplasty (THA) is a cornerstone intervention for Crowe Type 4 developmental dysplasia of the hip (DDH), a severe form characterized by complete hip dislocation and acetabular deficiency. This study aimed to evaluate the incidence of nerve injury in patients undergoing THA via trochanteric osteotomy and proximal femoral shortening, with a secondary focus on the impact of prosthesis type (cemented vs. cementless). MATERIAL AND
methodA prospective cohort study was conducted in Iran on 62 patients (81 hips) with Crowe Type 4 developmental dysplasia of the hip between 2020 and 2022. All procedures utilized a standardized direct lateral approach with trochanteric osteotomy and femoral shortening (3-4 cm). Nerve injury was assessed postoperatively via electromyography/nerve conduction velocity (EMG/NCV). Continuous variables were analyzed using independent t-tests, categorical variables with chi-square tests, and significance set at P < 0.05.
resultsIn this study, ultimately, 46 patients (62 hips) completed the study according to the protocol. Among the participants, 54 cases (87.1%) were female and 8 cases (12.9%) were male. The mean age and BMI of patients were 40.35 years and 25.19 Kg/m
conclusionTrochanteric osteotomy with proximal femoral shortening achieves substantial leg lengthening in Crowe Type 4 developmental dysplasia of the hip, with minimal nerve injury risk. Cementless prostheses demonstrated superior neurological safety, advocating for their preferential use.
