Subaxial Cervical Lateral Mass Screw and Rod Fixation: Surgical Experience and Outcome Analysis.
Observational study in Annals of African medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSubaxial cervical spine injuries (C3-C7) are common and often require stabilization due to their proximity to vital neurovascular structures. Posterior cervical spine surgery now commonly uses a lateral mass screw and rod fixation because of its biomechanical stability and versatility. This study aims to evaluate the long-term outcome and complications of this technique in tackling subaxial cervical spine pathologies. MATERIALS AND
methodsA 3-year prospective observational study conducted at our hospital on 50 adult patients with subaxial cervical spine instability was carried out. The parameters recorded included preoperative, intraoperative, and postoperative information, and results obtained regarding fusion and hardware placement were assessed at 3 and 6 months post surgery. The Frankel grading system was used for neurologic assessment; the radiologic outcomes were fusion rates and placement of the hardware.
resultsThe mean age of the patients was 47 years (68% of males), and a majority of cases (56%) were from trauma. At 6 months, 62% of the patients showed improvement in neurological condition - 20% in fully recovered (Grade E) condition. The overall fusion and success rates of hardware position were 88% and 96%, respectively. The complications included 4% with superficial infection and 6% transient radiculopathy, which were rare. Misplacement of screws occurred in 2%, and all caused minor neurological deficiencies.
conclusionOur study has supported lateral mass screw and rod fixation as an effective and reliable technique of stabilization of the subaxial cervical spine with substantial neurological recovery and a very low complication rate.
