METHODS: Thirty patients with a mean age of 43 years (range, 26-63) who suffered from instability of levels L4-L5 (n = 23), L5-S1 (n = 3), or both (n = 2) underwent surgery. Spondylodesis was achieved with two BAK cylinders. After 6 months, all patients completed a ...
transforaminal lumbar interbody fusionRetrospective cohort study.#The aim of this study was to compare outcomes in patients undergoing 1-level transforaminal lumbar interbody fusion (TLIF) at L4-S1.#TLIF is frequently performed at L4-S1 to treat degenerative lumbar pathologies. However, the native ...
Recent interest in laparoscopic spine surgery using threaded cages has resulted in questions regarding the ability to safely access the L4-L5 disc using this approach. The laparoscopic transperitoneal approach to L5-S1 is below the bifurcation of the great vessels, thus requiring minimal mobilization ...
Inadequate local curvature correction during posterior L4/5 fusion may lead to long-term loss of adjacent segment height, which is an independent risk factor for the development of ASD after fusion. Key words Lumbar fusion surgery; Adjacent segment...

Most frequent location of disc prolapse is L4-5, followed by L5-S1 and L3-4. The herniated discs tend to exert pressure on a specific nerve root. 3. Symptoms and signs Typically, patients with prolapsed intervertebral discs reveal both leg and back pain, with leg pain being their chief ...

This allows vascular invasion of the fusion mass from all sides, maximizes the interface between bone graft and bone, and ensures the development of the fusion mass at the biomechanically most appropriate site in a manner resembling external callus formation in fracture healing....
