Distal locked and unlocked nailing for perthrochanteric fractures--a prospective comparative randomized study.
Trial report in International orthopaedics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 2 of them syntheses 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
purposeIntramedullary nailing is widely used in the treatment of stable pertrochanteric fractures. However, it remains controversial whether the distal locking with intramedullary nailing is necessary.
methodIn this study, 70 patients over the age of 65 with pertrochanteric fractures (AO/OTA 31-A1 and A2) were enrolled and randomly divided into two groups for treatment by intramedullary nails either with or without distal locking. Intra-operative variables such as operation time, volume of blood loss, total fluoroscopy time, total length of incision, postoperative complications and clinical outcomes were recorded and compared between the two groups.
resultsA total of 29 patients in the locking group and 30 patients in the unlocking group completed one year of follow up. Operation time (39.2 ± 7.6 min), blood loss (158.6 ± 63.6 ml), fluoroscopy time (53.7 ± 3.9 s), and total length of incision (13.1 ± 2.1 cm) in the unlocking group were significantly decreased compared with the locking group (48.5 ± 9.0 min; 194.3 ± 61.6 ml; 57.8 ± 4.3 s; 10.9 ± 1.7 cm) (p < 0.05). No significant differences in postoperative complications and fracture union were identified between the two groups. Most patients in the locking group (80.0 %) and the unlocking group (77.1 %) recovered to their pre-injury activity levels.
conclusionThis study suggests that intramedullary nails without distal locking may be a reliable and acceptable option for treating stable pertrochanteric fractures (AO/OTA 31-A1 and A2) in elderly people. Distal unlocked nails showed subtle advantages in reducing blood loss, operation time, fluoroscopy exposure time, and size of the incision.
