AB  - OBJECTIVE: The aim of this study is to assess deformation of the tip and 
      deflection from the axis of 22-gauge Quincke needles when they are used for 
      diagnostic lumbar puncture (LP). Thus, it can be determined whether 
      constructional alterations of needles are important for predicting clinical 
      problems after diagnostic LP. MATERIALS AND METHODS: The 22-gauge Quincke needles 
      used for diagnostic LP were evaluated. A specially designed protractor was used 
      for measurement and evaluation. Waist circumference was measured in each patient. 
      Patients were questioned about headaches occurring after LP. RESULTS: A total of 
      115 Quincke-type spinal needles used in 113 patients were evaluated. No 
      deflection was detected in 38 (33.1%) of the needles. Deflection between 0.1 degrees  and 
      5 degrees  occurred in 43 (37.3%) of the needles and deflection >/= 5.1 degrees  occurred in 34 
      patients (29.6%). Forty-seven (41.5%) patients experienced post lumbar puncture 
      headache (PLPH) and 13 (11.5%) patients experienced intracranial hypotension 
      (IH). No statistically significant correlation between the degree of deflection 
      and headache was found (P > 0.05). Epidural blood patch was performed for three 
      patients. Deformity in the form of bending like a hook occurred in seven needles 
      and IH occurred in six patients using these needles. Two of the needles used in 
      three patients requiring blood patch were found to be bent. CONCLUSION: 
      Deformation of needles may increase complications after LP. Needle deformation 
      may lead to IH. In case of deterioration in the structure of the needle, 
      termination of the puncture procedure and the use of a new needle could reduce 
      undesirable clinical consequences, especially IH.
