Study summary

60 patients involved were divided into two matched groups; Group A: 30 patients were treated with conventional fenestration laminectomy and discectomy and Group B: 30 patients were treated with microdiscectomy. The age of the patients involved in this study ranged from 19 years old to 46 years old

Read the detailed description

60 patients involved were divided into two matched groups; Group A: 30 patients were treated with conventional fenestration laminectomy and discectomy and Group B: 30 patients were treated with microdiscectomy. The age of the patients involved in this study ranged from 19 years old to 46 years old. All the patient was suffering from symptomatic lumbar disc herniation L4-5. Each patient was assessed clinically and MRI was done for all the patients to prove clinically, the symptomatic lumbar disc herniation which was present in all patients.

What researchers measure

Primary outcomes

  1. Visual analogue score

    Visual analogue score of back pain and leg pain which represent a score from 0-10 so if patient has no pain so gives 0 and if has severe pain gives 10

    Time frame: Visua analogue score was assessed preoperatively and postoperatively to see how much change in pain can occurred after open discectomy and after Microdiscectomy for 1 year

  2. Oswestry disability index

    Oswestry disability index in a measurement of functional ability of patients regarding pain and daily activities

    Time frame: Oswestry disability index was assessed preoperatively and postoperatively to assess how much changes can occur after open discectomy and Microdiscectomy for 1 year after surgery
