Lumbar microdiscectomy recovery data

Operation studied

Microdiscectomy — removal of a herniated or bulging disc at a single lumbar level, often combined with a hemilaminectomy to decompress the affected nerve root. One midline or para-midline incision, closed with Dermabond.

Reported at

0-2 wk (Phase 1, wound healing/protection), 2-6 wk (Phase 2, initial strength), 6-8 wk (Phase 3, advanced strength), 8-12 wk (return to running/sport)

What it reports

• The protocol restricts lifting to under 15 lb for the first 2 weeks after surgery.
• The protocol limits sitting, including in the car, to no more than 30 minutes at a time during weeks 0-2, with standing and walking breaks, and tells patients to avoid bending, twisting, pushing, and pulling in that window.
• The protocol allows driving once the patient is off narcotic pain medication and can tolerate sitting for more than 15 minutes at a time, which it places at 1-2 weeks.
• The protocol prescribes a walking program starting at 10 minutes, 1-2 times a day, gradually increasing to 20 minutes at a time during weeks 0-2.
• From 2 to 6 weeks, the protocol allows walking as cardio up to 30 minutes at a time.
• The protocol starts a recumbent stationary bike at 2 weeks, an upright stationary bike without resistance at 4 weeks, and adds resistance on the upright bike at 6 weeks.
• The protocol allows aquatic physical therapy starting at 2 weeks, once the incision has healed with no scabs, avoiding rotation and using walking and multi-directional arm movements in the water.
• From 2 to 6 weeks, the protocol begins lifting at 15 lb and progresses it until there are no lifting restrictions at week 6, while keeping the lumbar spine neutral and avoiding bending and twisting below the knees.
• The protocol typically releases patients to full activity without restrictions at 6 to 8 weeks, once they are independent in their home exercise program.
• The protocol allows swimming, elliptical, and outdoor cycling at 6 weeks, and skiing, yoga, or Pilates at 8 weeks.
• The protocol places running, soccer, golf, and basketball, along with plyometrics and return to sport, at 8 to 12 weeks, criteria dependent on progress through the program.
• The Silverlon wound dressing can be removed after 5 days; the incision can get wet but should not be submerged, and no lotions, balms, ointments, or oils should be applied to it.

Operation studied

open or minimally invasive lumbar discectomy surgery with a posterior midline or paracentral approach, for degenerative pathology

Measures

leg pain NRS (0-10, higher = worse) · back pain NRS (0-10, higher = worse) · Oswestry Disability Index (ODI, modified) (0-100, higher = worse)

Reported at

preop, 3 mo, 12 mo, 24 mo

Follow-up

24 months

What it reports

• Among 517 patients tracked for leg pain, three recovery patterns emerged. 18.4% recovered to almost no leg pain: average leg pain fell from 7.5 out of 10 before surgery to 0.8 by 3 months, 0.2 by 12 months, and 0.0 by 24 months.
• 55.4% of the leg-pain cohort improved but landed low and plateaued: average leg pain fell from 7.5 out of 10 before surgery to 2.3 by 3 months, and stayed at 2.3 through 12 and 24 months.
• 26.3% of the leg-pain cohort improved little: average leg pain fell from 8.1 out of 10 before surgery to 6.1 by 3 months, 6.4 by 12 months, and 6.4 by 24 months.
• At 12 months, in the leg-pain 'excellent' group all patients (100%) reached the minimal important pain reduction and 90.6-91.8% counted as a clinical success (50% improvement or an ODI score of 22 or below); in the 'good' group 88.0% reached the minimal important reduction and 62.5-64.8% counted as a clinical success; in the 'poor' group 35.2% reached the minimal important reduction and 18.2-22.4% counted as a clinical success.
• For back pain, among 469 patients, three groups emerged: 13.0% recovered to almost no back pain (falling from 6.2 to 0.8 by 3 months, 0.3 by 12 months, 0.1 by 24 months, all out of 10); 56.4% improved and plateaued (falling from 6.5 to 2.6 by 3 months, 2.4 by 12 months, 2.4 by 24 months); 30.6% improved little (falling from 7.6 to 5.5 by 3 months, then rising slightly to 6.4 by 12 months and 6.2 by 24 months).
• For disability, measured with the Oswestry Disability Index (0-100, higher is worse), among 502 patients: 59.7% had an 'excellent' recovery, falling from 46.3 before surgery to 16.5 by 3 months, 10.3 by 12 months, 9.6 by 24 months; 35.6% had a 'fair' recovery, falling from 55.1 to 39.9 by 3 months, 38.3 by 12 months, 37.8 by 24 months; 4.7% had a 'poor' recovery, starting at 68.4 and staying between about 63 and 67 through 24 months.
• The paper describes a disconnect between pain and disability recovery: 95.3% of patients showed good-to-excellent disability recovery, but 26.3-30.6% of patients still reported persistent leg or back pain after surgery.

Measures

Roland Disability Questionnaire for Sciatica (0-23, higher = worse) · Leg pain, visual analogue scale (VAS) (0-100 mm, higher = worse) · Back pain, visual analogue scale (VAS) (0-100 mm, higher = worse) · Global perceived recovery (7-point Likert) (1-7 (dichotomised to satisfactory/unsatisfactory), higher = worse) · SF-36 Bodily Pain subscale (0-100, higher = better) · SF-36 Physical Functioning subscale (0-100, higher = better)

Reported at

Follow-up

2 years (104 weeks)

What it reports

• This trial randomly assigned 283 people who had had sciatica (leg pain from a herniated disc) for 6 to 12 weeks to either early surgery (141 people) or prolonged conservative care with surgery only if needed later (142 people).
• In the end, 125 of the 141 people assigned to early surgery (89%) actually had microdiscectomy; 16 of 141 (11%) recovered on their own before their scheduled surgery happened. Median time from randomisation to surgery was 1.9 weeks.
• In the conservative-care group, 62 of 142 people (44%) eventually needed surgery — 55 of them within the first year, a median of 14.6 weeks after randomisation, and 7 more in the second year.
• Leg pain (VAS, 0-100, higher is worse) in the early-surgery group fell from 67.2 at the start to 10.2 by 8 weeks, 8.4 by 26 weeks, 11.0 by 52 weeks (1 year), and 11.0 by 104 weeks (2 years).
• Leg pain in the conservative-care group fell more slowly at first: from 64.4 at the start to 27.9 by 8 weeks and 14.5 by 26 weeks, then caught up to the surgery group at 11.0 by 52 weeks and 9.0 by 104 weeks.
• Back pain (VAS, 0-100) in the early-surgery group went from 33.8 at the start to 14.4 at 8 weeks, 15.5 at 26 weeks, 14.2 at 52 weeks, and 15.9 at 104 weeks; back pain fell less sharply than leg pain and did not keep improving after 8 weeks.
• Back pain in the conservative-care group went from 30.8 at the start to 25.7 at 8 weeks, 17.8 at 26 weeks, 16.5 at 52 weeks, and 17.3 at 104 weeks.
• Disability (Roland Sciatica scale, 0-23, higher is worse) in the early-surgery group fell from 16.5 at the start to 6.1 at 8 weeks, 4.0 at 26 weeks, 3.3 at 52 weeks, and 3.1 at 104 weeks.
• Disability in the conservative-care group fell from 16.3 at the start to 9.2 at 8 weeks, 4.8 at 26 weeks, 3.7 at 52 weeks, and 2.6 at 104 weeks.
• By 8 weeks, 81.2% of the early-surgery group rated their recovery as satisfactory or nearly complete, versus 36.5% of the conservative group. The gap narrowed over time: 77.4% vs 70.8% at 26 weeks, 85.7% vs 82.5% at 52 weeks, and 81.3% vs 78.9% at 104 weeks.
• By the end of year one, 95% of people in both groups had reported a satisfactory recovery at some point, though the early-surgery group got there faster (their pace of recovery in year one was about twice as fast, hazard ratio 1.97, 95% CI 1.72 to 2.22).
• At two years, 20% of all patients (56 of 281 with data) still rated their outcome unsatisfactory, with no significant difference between the two groups (81.3% vs 78.9% satisfactory, P=0.66) — early surgery sped up relief but did not lower the overall chance of a poor long-term outcome.
• 6% of people who had surgery in either group needed a second operation for recurrent sciatica within two years — 7 people in the early-surgery group and 4 in the conservative group.
• Surgical complications occurred in 1.6% of all operated patients: two dural tears (a small tear in the membrane around the nerves) and one wound haematoma (a pocket of blood at the incision), none needing further treatment. No one developed a new neurological deficit from surgery or from conservative care.
• SF-36 bodily pain score (0-100, higher is better) in the early-surgery group rose from 21.9 at the start to 62.8 at 8 weeks, 76.1 at 26 weeks, 81.2 at 52 weeks, and 78.4 at 104 weeks; the conservative group rose from 23.9 to 54.4, 72.8, 78.5, and 80.7 at the same timepoints.

What it does not report

Return to work rate or timing as an outcome. The paper only reports baseline sick-leave status (76% of the surgery group and 82% of the conservative group had taken sick leave before enrolling, average about 5.3 weeks each) and a general note that patients were advised to resume work from six weeks onward — it does not report what fraction of either group had actually returned to work by any given week. · Driving, sleep, or sport/return-to-activity outcomes — none of these are reported. · Week-by-week pain values between the reported checkpoints. The methods list assessments at 2, 4, 12, 38, and 78 weeks in addition to the headline 8/26/52/104-week timepoints, but the results tables in the fetched text only give numeric leg pain, back pain, disability, and SF-36 scores at baseline, 8, 26, 52, and 104 weeks — values at 2, 4, 12, 38, and 78 weeks are not printed as numbers in the text reviewed.

Operation studied

lumbar microdiskectomy for degenerative disc herniation (excludes spinal stenosis, percutaneous diskectomy, artificial disk/arthroplasty, laminectomy, fusion, and cauda equina symptoms)

Reported at

not reported as discrete timepoints; pooled averages are reported, with a meta-regression against duration of follow-up across studies

Follow-up

varies by pooled study; not stated as a single value in the abstract

What it reports

• This review pooled 31 studies on return to work after lumbar microdiscectomy, screened from 2285 records; most of the studies had a low risk of bias.
• Pooling 21 of those studies, on average 78 out of 100 people had returned to work after surgery (95% CI 71%-83%).
• Pooling 13 of those studies, the average time to return to work was 4.79 weeks (95% CI 3.88-5.70 weeks).
• People followed for longer after surgery were slightly more likely to have returned to work by the time they were checked, but the effect was small (meta-regression coefficient 0.02, 95% CI 0.01-0.03, p=0.006).
• How long someone had symptoms before surgery did not significantly change whether they returned to work.
• The review's conclusion: about 70% to 80% of people return to work within the first month and a half after surgery, and returning after that point is uncommon.

Operation studied

lumbar microdiscectomy — relieving pressure on the affected lumbar nerve root by removing part of the intervertebral disc and ligamentum flavum, using a surgical microscope — followed by physiotherapy (median start 14 wk postop, IQR 8–26 wk)

Measures

VAS leg pain (0-100mm, higher = worse) · VAS back pain (0-100mm, higher = worse) · Roland Disability Questionnaire (RDQ) (0-24, higher = worse)

Reported at

preop (baseline VAS/RDQ only); return-to-work status tracked continuously to 52 wk postop

Follow-up

52 weeks

What it reports

• 178 of 257 patients (69.3%) had fully returned to their original job, with no changes to tasks or hours, by 52 weeks after surgery.
• Among those who fully returned, the median time to full return to work was 16.0 weeks (IQR 14.0-16.0 weeks).
• There was an 85% probability of having returned to work within the first 26 weeks after surgery.
• Separately from full return, 23 patients (9.0%) had moved to a less physically demanding role, 30 patients (11.7%) stayed in their original role but with modified tasks, 17 patients (6.6%) took a different job with similar physical demands, and 9 patients (3.4%) had a work status that could not be classified — the paper does not give a median time for these partial/modified returns.
• Before surgery, leg pain (VAS, 0-100mm) was a median of 75.0 (IQR 55.4-87.1).
• Before surgery, back pain (VAS, 0-100mm) was a median of 49.8 (IQR 20.0-74.0).
• Before surgery, disability (Roland Disability Questionnaire, 0-24) was a median of 17.0 (IQR 14.0-20.0).
• People with a higher education level returned to work faster: adjusted hazard ratio 2.01 (95% CI 1.37-2.95, p<0.001), after adjusting for age, sex and leg pain.
• Self-employed people returned to work faster: adjusted hazard ratio 1.73 (95% CI 1.08-2.78, p=0.01).
• People without predominantly physical jobs returned to work faster: adjusted hazard ratio 1.49 (95% CI 1.49-2.81, p=0.01) — the paper prints the lower confidence bound as equal to the hazard ratio itself; copied as printed.
• People with a high preoperative disability score (RDQ) returned to work more slowly: adjusted hazard ratio 0.50 (95% CI 0.35-0.71, p<0.001).

What it does not report

Pain (VAS) or disability (RDQ) scores at any postoperative timepoint — only preoperative baseline values are reported. · Surgical complication rates — not reported; the paper only notes postoperative imaging was not routine. · Driving, sleep, or return to sport — not mentioned anywhere in the paper. · A median or range specifically for time to partial/modified return to work (only full-return timing is given a median).
