CCD angle & hip fractures - Predictor of fracture symmetry?
Article in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
backgroundHip fracture caused by fall is a common injury of the elderly. The risk of sustaining a contralateral hip fracture has been reported to be 5-10%. Aging society heightens the need of efficient prevention tools. To be able to cope with this demand, understanding of biomechanics of hip fractures are mandatory. Previous studies suggest that geometry of the proximal femur could play an important role for fracture probability and fracture type. Thus, analysis of hip geometry could play an important role in the prediction and prevention of bilateral hip fractures. Aim of this study was to elucidate the influence of caput collum diaphyseal angle on the fracture type of proximal femur. MATERIAL AND
methodsIn a retrospective analysis, data of patients with an acute hip fracture who underwent surgical treatment within five years were included. Data was separated into two groups: (I) intra capsular femur fracture (femoral neck fractures) and (II) extra capsular femur fracture (inter- and subtrochanteric femur fractures). Occurrence of a bilateral fracture, age, gender, weight, height and caput collum diaphyseal angle (standardized measurement of the opposite joint on preoperative digital x-rays) of each group were further analyzed.
resultsData of 448 patients were included ((I): 250 vs. (II): 198 patients). Group (I) showed a significant higher mean caput collum diaphyseal angle of 133.9 ± 7.0° (mean ± standard deviation) compared to group (II) with 127.6 ± 6.1° (F (1, 451) = 106.5, p = 0.00). In group (I) 0 patients had a caput collum diaphyseal angle <120° (varus), 214 patients (86%) 120°-140° and 35 patients (14%) angle>140° (valgus). In contrast, in group (II) 21 patients (10%) had a caput collum diaphyseal angle <120° (varus), 175 patients (86%) 120°-140° and 7 patients (4%) >140° (valgus). 52 patients had a bilateral hip fracture. 36 patients (69%) sustained a bilateral hip fracture of the same fracture type.
conclusionPatients with an intra capsular proximal femur fracture showed a significantly higher caput collum diaphyseal angle compared to patients with an extra capsular proximal femur fracture. Moreover, intra capsular femur fractures are correlated with an indifferent (120-140°) or valgus (>140°) femoral neck configuration. Extra capsular femur fractures correlate with an indifferent (120-140°) or varian femoral neck configuration (<120°). The results support the assumption that the caput collum diaphyseal angle has an influence on fracture type of the proximal femur. This could possibly be a predictor for the fracture type of the contralateral hip (second fracture). Based on this, present data may benefit prosthetists in developing new and more efficient hip protectors. LEVEL OF EVIDENCE: Level III. Retrospective comparative study.
