Summary
Mini open discectomy for lumbar disc herniation offers satisfying outcomes, with nearly two-thirds of patients maintaining good results after 15 years. This reliable surgical technique is effective when indications are met, avoiding complications from excessive instrumentation.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Lumbar disc herniation is a common condition requiring surgical intervention.
- Mini open discectomy is a frequently used procedure with generally positive short-term outcomes.
Purpose of the Study:
- To evaluate the long-term efficacy and outcomes of mini open discectomy for lumbar disc herniation.
- To assess the durability of results beyond one year post-surgery.
Main Methods:
- Retrospective review of 552 patients undergoing mini open discectomy between 1993 and 2013.
- Long-term follow-up using a modified Stauffer and Coventry classification and Oswestry Disability Index.
Main Results:
- Good to very good outcomes were observed in 87.3% at one year, decreasing to 63.7% at an average of 14.7 years.
- The Oswestry Disability Index improved by 35 points. Re-operation rates for recurrence or fusion were 10.68% over the follow-up period.
- Post-operative recurrences occurred in 9.2% of cases, with adjacent level herniation in 5.2%.
Conclusions:
- Mini open discectomy remains a reliable surgical option for lumbar disc herniation when indications are carefully selected.
- The procedure demonstrates sustained satisfactory outcomes at approximately 15-year follow-up, with fewer complications than extensive instrumentation.
- Further randomized controlled trials are recommended to validate these long-term findings.

02:24Predicting Reaction Outcomes
10.8K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

01:13Outcomes of Glycolysis
107.1K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:11Guidelines for Writing Outcome
3.8K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

01:14Directional Terms
16.2K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...
