Mismatch of short straight proximal femur nails with anterior bow of femur in Indian population- A radiological and functional analysis.
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 3 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
introductionIntra-medullary devices are the most common mode of fixation of inter-trochanteric fractures. Short proximal femur nails (PFN) used for fixing these fractures, unlike the long nails, are non-anatomic and are usually straight with no curvature in antero-posterior plane. As a result, there is always a chance of the nail tip impinging against the anterior cortex of femur. MATERIALS AND
methodsA total of 80 patients with trochanteric fractures (AO 31A2 and 31A3), operated with short PFN, were followed up retrospectively and prospectively from 2019 to 2021, for a period of 6 months. All fractures were fixed with PFNs, with nails ranging from 170 to 250 mm. Radiological analysis was done on hip lateral X-rays (taken at 6 months) using Angle at Distant Axis (ADA) and Nail Tip Position (NTP). Functional outcome analysis was done using Harris Hip Score. Patients were graded into 2 groups according to ADA (ADA>4° and ADA<4°). Incidence of anterior thigh pain was noted in patients on follow up and was statistically evaluated with nail size, nail diameter, ADA and NTP.
resultsMean ADA was 4.19° ± 1.45; mean NTP grade was 1.98 ± 1.11. Mean nail size was 201.87 mm with a mean nail diameter of 9.76 mm. Twenty patients complained of anterior thigh pain on follow-up. Twenty-five patients had NTP grade 3 or above of which 16 complained of anterior thigh pain (p < 0.001). Fifty-five patients had nail diameter of 10 mm or above of which 14 had anterior thigh pain (p < 0.01). Fifty-three patients had a nail length of 200 mm or above of which 16 patients complained of thigh pain on follow up (p < 0.01).
conclusionThere is a mismatch of short PFNs with anterior bow of femur. Use of shorter nails with narrow diameters will avoid this mismatch to an extent.
