Predictors of the outcome of lumbar disc herniation following classical surgery

Abstract

Pain duration and age are predictive of estimated blood loss. Patient age is also predictive of the postoperative VAS back score.

Database analysis comparing incidence and complication rates between inpatient and outpatient laminotomies for lumbar disc herniation

“…In the outpatient cohort, the demographics with the highest incidence were male patients between 35–44 and 55–64 years old. These results coincide with the results of prior literature that have shown the incidence of LDH to be most common in middle-aged men with the incidence of inpatient spinal surgery to be higher in elderly patients [ 6 , 7 , 18 ]. These differences are likely attributed to the fact that patients receiving inpatient procedures have significantly more comorbidities, which aligns with the results shown in this study as well.…”

“…Lumbar disc herniation (LDH) is a common source of back and leg pain among adults, with an incidence ranging from 5 to 20 cases per 1000 adults annually [ [2] , [3] , [4] , [5] ]. The prevalence of herniated lumbar discs has a male-to-female ratio of 2:1 and is most common between patients 25 to 55 years of age [ 6 , 7 ]. Disc herniation is the displacement of the nucleus pulposus or annulus fibrosis through the intervertebral disc space [ 8 ].…”

“…Ninety-five percent of disc herniations occur at the L4–L5 or L5–S1 levels [ 11 ]. This displacement can cause nerve root compression, leading to radicular pain, numbness, and weakness in the areas supplied by the nerve root [ 6 , 9 , 10 ].…”

“…While most LDHs resolve spontaneously, one surgical intervention that has proven effective for refractory LDH is a laminotomy with discectomy [ 6 , 12 , 13 ]. The benefits of a laminotomy include short procedure times, minimal blood loss, and a low risk of epidural scarring and cord trauma [ 12 ].…”

Preoperative ODI and Intake of Analgesics Predict Outcome after Lumbar Microdiskectomy: Results from a Prospective Register

“…Many efforts have been made to define predictors for such outcomes. 2,3 LDH often results in radicular pain and numbness, and may even induce paresis. Typical clinical presentation of LDH includes initial lumbar back pain and resulting disability, which can lead to immobility and inability to work.…”
