The patient was undergoing spinal anesthesia in preparation to give birth to her child.A 27g bd whitacre needle was used for this procedure.It is reported that bony resistance was encountered during the needle insertion and after 2-3 attempts it was decided to change the spinal needle.As the needle was withdrawn from the patient it was noticed that approximately 2 cm of the tip of the needle was missing.Another attempt was made with a different needle and spinal anesthesia was performed successfully.After the patient delivered her baby, a portable x-ray of the patient's lumbar spine was done revealing the broken spinal needle at the level of the patient sl3 vertebrae.A ct scan of the patient's lumbar spine was done the next day which showed the retained needle fragment in the patient's paravertebral muscle, behind the lateral to the spinous process of the l3 vertebrae.The patient then had a consultation with a spinal surgeon who reassured her that the retained fragment will not cause any harm and that they would discuss its removal in a follow up appointment.
