What Spinal Conditions and Problems Do Our Surgeons Treat?
Spinal surgery addresses diverse pathology affecting all spinal regions from cervical through sacral spine.
Degenerative Spinal Conditions
Lumbar Disc Herniation
Intervertebral discs develop tears in outer fibrous rings, allowing inner gel-like nucleus to extrude (herniate) into the spinal canal or neural foramina, compressing nerve roots. Lumbar disc herniations commonly affect L4-L5 or L5-S1 levels, causing sciatica, sharp shooting leg pain radiating down buttock and leg following specific nerve distribution (L5 nerve causes pain down the lateral leg to the big toe; S1 nerve causes pain down the posterior leg to the lateral foot), often with numbness, tingling, weakness, and sometimes severe back pain.
Lumbar Spinal Stenosis
Narrowing of the spinal canal (central stenosis) or neural foramina (foraminal stenosis) from degenerative changes, facet joint arthritis, ligamentum flavum hypertrophy (thickening), disc bulging, and bone spurs (osteophytes). Typically affects people over 60.
Degenerative Spondylolisthesis
One vertebra slips forward relative to the vertebra below (usually L4 slipping forward on L5) from degenerative facet joint arthritis and disc degeneration. Causes back pain and sometimes nerve compression (stenosis, radiculopathy).
Cervical Disc Herniation
Similar to lumbar disc herniation but in the neck, compressing cervical nerve roots causing neck pain with arm pain (cervical radiculopathy), numbness, tingling, weakness in specific arm distribution (C5 nerve, shoulder/biceps; C6, thumb and biceps; C7, middle finger and triceps; C8,pinky finger and grip strength).
Cervical Spondylotic Myelopathy
Degenerative cervical spine changes (disc bulging, bone spurs, ligament thickening) cause spinal cord compression (myelopathy, spinal cord dysfunction), causing hand clumsiness and weakness, gait instability and falls, bowel/bladder dysfunction in severe cases, and neck pain sometimes (but cervical myelopathy can be painless despite significant cord compression).
Thoracic Disc Herniation
Rare compared to cervical and lumbar disc herniation. Thoracic disc herniation can cause thoracic radiculopathy (chest wall pain) or thoracic myelopathy (spinal cord compression causing leg weakness, gait difficulty, bowel/bladder dysfunction). Surgical treatment is technically challenging, posterior approaches risk spinal cord injury, and anterior or lateral approaches are often used, requiring thoracic surgeon collaboration in some cases.
Spinal Deformity
Scoliosis
Lateral curvature of the spine with a rotational component. Multiple types exist:
- Idiopathic Scoliosis
- Congenital Scoliosis
- Neuromuscular Scoliosis
- Adult Degenerative Scoliosis:
Kyphosis
Excessive forward curvature (thoracic spine normally has mild kyphosis, 20-40 degrees; excessive kyphosis exceeds 50-60 degrees).
Spinal Trauma
Cervical Fractures and Dislocations
High-energy trauma (motor vehicle accidents, falls from height, diving accidents) causes cervical spine fractures ranging from stable compression fractures (treated with collar immobilisation) to highly unstable burst fractures, facet dislocations, or fracture-dislocations causing spinal cord injury.
Unstable cervical fractures require surgical stabilization, anterior plating, posterior instrumentation, or combined approaches depending on fracture pattern. Cervical spinal cord injuries are devastating, high cervical injuries (C1-C4) often cause quadriplegia and respiratory failure requiring mechanical ventilation; mid-lower cervical injuries (C5-C8) cause varying degrees of arm and leg paralysis depending on level.
Early surgery (within 24 hours of injury when possible) decompressing spinal cord and stabilizing fracture improves neurological recovery outcomes.
Thoracolumbar Fractures
Thoracolumbar junction (T12-L2) is common fracture site, transition from rigid thoracic spine (supported by ribcage) to mobile lumbar spine creates stress concentration. Fractures range from stable compression fractures (anterior vertebral body compresses, posterior elements intact, treated non-operatively with bracing) to unstable burst fractures (vertebral body shatters with bone fragments retropulsed into spinal canal, posterior elements disrupted) requiring surgery.
Surgical treatment involves posterior instrumentation (pedicle screws and rods stabilizing fractured vertebra and adjacent levels), sometimes with anterior column reconstruction (removing fractured bone fragments, placing structural graft or cage supporting anterior column).
Spinal Cord Injury
Traumatic spinal cord injury causes complete (no motor or sensory function below injury level) or incomplete (partial function preserved) paralysis. Spinal cord injury is life-altering, affecting mobility, independence, bowel/bladder/sexual function, sensation, employment, relationships, and requiring lifelong adaptations.
Immediate spinal cord injury management includes high-dose methylprednisolone (controversial, benefits unclear, side effects significant, but sometimes administered within 8 hours of injury), urgent MRI assessing spinal cord compression, decompression surgery within 24 hours when cord compression exists (earlier decompression associated with better neurological recovery), and stabilization of unstable fractures.
Comprehensive spinal cord injury rehabilitation is prolonged complex process involving inpatient rehabilitation, physiotherapy and occupational therapy retraining function, bladder and bowel management, preventing complications (pressure ulcers, deep vein thrombosis, respiratory complications, autonomic dysreflexia), psychological support, and social reintegration.
Neurological recovery is variable. Complete injuries rarely recover significantly, though early incomplete injuries (ASIA B, C, D) often improve with time and rehabilitation. Maximum neurological recovery typically occurs within 18-24 months of injury, though some improvement continues beyond.
Spinal Infections
Discitis and Osteomyelitis
Bacterial infection of intervertebral disc (discitis) and/or adjacent vertebrae (osteomyelitis), usually from haematogenous spread (bacteria in bloodstream seeding spine), occasionally from direct inoculation (spinal surgery, spinal injections). Common organisms include Staphylococcus aureus (most common), Streptococcus species, and Gram-negative organisms.
Symptoms include severe back pain (often constant, unrelieved by position changes), fever, elevated inflammatory markers (CRP, ESR), sometimes neurological deficit if abscess forms compressing spinal cord or nerves.
Diagnosis involves MRI (showing disc and bone marrow oedema, enhancement with contrast), blood cultures (positive in 40-60% of cases), and sometimes CT-guided biopsy (obtaining tissue for culture and sensitivity).
Treatment is primarily medical, prolonged intravenous antibiotics (6-12 weeks typically based on organism and clinical response). Surgery is indicated for abscess causing spinal cord compression (urgent decompression), spinal instability or deformity, failure of medical treatment, or biopsy when organism isn’t identified by blood cultures.
Spinal Tuberculosis (Pott's Disease)
Tuberculosis affecting spine, common in South Africa given high TB prevalence. Typically affects vertebral bodies causing destruction, collapse, kyphotic deformity (gibbus), and sometimes neurological deficit from spinal cord compression by abscess or kyphotic deformity.
Treatment is primarily anti-tuberculous chemotherapy (6-12 months). Surgery is indicated for neurological deficit, significant kyphotic deformity, or instability, debridement, decompression, reconstruction with bone graft, and instrumented stabilization.
Epidural Abscess
Pus collection in epidural space (outside spinal cord dura) causing spinal cord compression, surgical emergency. Typical presentation: back pain, fever, then rapidly progressive weakness, sensory loss, bowel/bladder dysfunction over hours to days.
Requires urgent MRI diagnosis, immediate neurosurgical consultation, emergency surgery (laminectomy, abscess drainage, decompression), and prolonged IV antibiotics. Prognosis depends critically on pre-operative neurological status, patients with complete paralysis pre-operatively often remain paralysed despite surgery, those operated before severe neurological deficit often recover fully. This is why early diagnosis and urgent surgery matter profoundly.
Spinal Tumours
Metastatic Spinal Tumours
Most common spinal tumours (vastly more common than primary bone tumours). Cancers commonly metastasizing to spine include breast, prostate, lung, kidney, thyroid, multiple myeloma. Vertebral metastases cause pain, pathological fractures (fracture through weakened tumour-infiltrated bone), and spinal cord compression (oncological emergency).
Presentation: progressively worsening back pain (worse at night, unrelieved by rest), sometimes pathological fracture causing sudden severe pain, sometimes spinal cord compression causing weakness, sensory loss, bowel/bladder dysfunction (evolving over days to weeks).
Treatment depends on tumour type, extent of disease, overall prognosis, neurological status, and spinal stability. Options include radiation therapy (primary treatment for radiosensitive tumours, breast, prostate, myeloma), surgery (decompression, stabilization with instrumentation, sometimes tumour resection, indications include radioresistant tumours, unstable fractures, progressive neurological deficit despite radiation), vertebroplasty/kyphoplasty (cement augmentation stabilizing painful fractures), and systemic therapy (chemotherapy, hormonal therapy, targeted therapy depending on primary cancer).
Metastatic spinal cord compression is oncological emergency, requires urgent MRI, high-dose corticosteroids, urgent radiation or surgical decompression. Prognosis for neurological recovery depends on pre-treatment neurological status and how quickly treatment is initiated, patients with preserved ability to walk have good prognosis maintaining ambulation; patients who lose walking ability for over 48 hours before treatment rarely regain walking.
Primary Spinal Tumours
Rare compared to metastases. Include benign tumours (osteoid osteoma, osteoblastoma, aneurysmal bone cyst, giant cell tumour, haemangioma) and malignant tumours (osteosarcoma, chondrosarcoma, Ewing’s sarcoma, chordoma, particularly at sacrum).
Treatment varies by tumour type, benign tumours often require surgical excision, malignant tumours require wide resection (en bloc spondylectomy when possible, removing entire vertebra with tumour margins), often combined with chemotherapy and/or radiation.
Intradural Spinal Tumours
Tumours arising within spinal canal from nerve roots (schwannomas, neurofibromas) or spinal cord itself (astrocytomas, ependymomas). Cause progressive neurological deficit from spinal cord or nerve root compression.
Treatment is surgical, laminectomy, opening dura, microsurgical tumour resection. Nerve sheath tumours (schwannomas, neurofibromas) are usually completely resectable with excellent outcomes. Intramedullary tumours (within spinal cord substance) are more challenging, resection risks neurological injury, but modern microsurgical techniques and intraoperative monitoring enable safe resection in many cases.
Other Spinal Conditions
Cauda Equina Syndrome
Fluid-filled cyst (syrinx) within spinal cord causing progressive neurological dysfunction, dissociated sensory loss (loss of pain/temperature sensation whilst touch/position sense preserved), weakness, sometimes scoliosis. Associated with Chiari malformation (cerebellar tonsils descend into foramen magnum obstructing CSF flow), post-traumatic (after spinal cord injury), or idiopathic.
Treatment addresses underlying cause (Chiari decompression, syrinx drainage or shunting). Progressive syringomyelia untreated causes permanent spinal cord damage.
Spinal Arteriovenous Malformations (AVMs)
Abnormal tangle of blood vessels in or around spinal cord causing neurological dysfunction from venous congestion, haemorrhage, or steal phenomenon. Rare but serious, can cause progressive myelopathy or sudden paralysis from haemorrhage.
Diagnosis requires spinal angiography. Treatment options include endovascular embolization, microsurgical resection, or sometimes radiosurgery depending on AVM type and location.
Tethered Cord
Spinal cord abnormally attached to surrounding structures preventing normal ascent within spinal canal during growth. Causes progressive neurological dysfunction in children (back pain, leg weakness, bowel/bladder problems, foot deformity, scoliosis) or sometimes adults (adult tethered cord syndrome).
Treatment involves microsurgical release (detethering), opening dura, identifying and dividing tethering structures (tight filum terminale, scar tissue, lipoma, other causes), freeing spinal cord. Surgery halts progression and sometimes improves neurological function.
Why Choose Botshilu for Spinal Surgery
Spinal surgery requires exceptional surgical skill, meticulous technique, a comprehensive understanding of spinal anatomy and biomechanics, and commitment to patient safety, given surgery’s inherent risks.
Botshilu’s Spinal Surgery services offer:
Experienced Spinal Surgeons:
Our spinal surgeons have completed comprehensive training, medical school, orthopaedic surgery or neurosurgery residency (5-6 years), additional fellowship training in spinal surgery, registration with HPCSA as specialists, years of experience performing diverse spinal procedures, and ongoing professional development, maintaining current knowledge of evolving techniques and technologies. When surgery involves the spine, the structure protecting the spinal cord, whose injury causes permanent paralysis, the surgeon’s experience and expertise matter profoundly.
Modern Surgical Techniques:
Spinal surgery has evolved dramatically. We utilise contemporary approaches including minimally invasive techniques when appropriate (smaller incisions, less muscle disruption, faster recovery for suitable cases, microdiscectomy for herniated discs, minimally invasive decompression for stenosis, percutaneous pedicle screw fixation for some fractures and fusions), traditional open surgery when necessary (complex deformity, revision surgery, extensive decompressions, tumour resections require open approaches providing superior visualisation and access), image guidance and navigation (fluoroscopy, sometimes CT-based navigation improving screw placement accuracy, reducing radiation exposure, enhancing safety), and intraoperative neuromonitoring (monitoring spinal cord and nerve root function throughout surgery, immediate feedback if neurological structures are compromised, dramatically improving safety particularly for complex deformity correction, tumour surgery, or procedures near spinal cord).
We select techniques based on individual patient anatomy, pathology, and surgical goals, not using minimally invasive approaches inappropriately when open surgery provides better outcomes, nor using unnecessarily extensive approaches when minimally invasive techniques are adequate.
Comprehensive Surgical Capabilities:
We perform the full range of spinal procedures including discectomy (removing herniated disc fragments compressing nerves), laminectomy and decompression (removing bone and ligament creating space for compressed spinal cord or nerve roots), spinal fusion (joining vertebrae with bone graft and instrumentation, screws, rods, creating solid bone bridge eliminating painful motion or stabilising unstable segments), vertebroplasty and kyphoplasty (injecting cement into fractured vertebrae, stabilising osteoporotic compression fractures, reducing pain), spinal fracture fixation (stabilising traumatic fractures with instrumentation), deformity correction (correcting scoliosis, kyphosis using instrumented fusion), spinal tumour resection (removing tumours involving spine, primary bone tumours, metastatic disease), and cervical, thoracic, and lumbar procedures (operating on all spinal regions).
Modern Spinal Instrumentation:
Contemporary spinal surgery uses sophisticated instrumentation enabling stable fixation and fusion including pedicle screw systems (titanium screws inserted through pedicles, bony pillars connecting vertebral body to posterior elements, providing extremely secure fixation), rods connecting screws (creating rigid construct stabilising multiple levels), interbody cages (titanium or PEEK cages filled with bone graft inserted between vertebral bodies, restoring disc height, supporting fusion, providing immediate structural support), bone graft (autograft from patient’s iliac crest, gold standard for fusion but requires separate incision and causes donor site pain, or allograft from bone bank, or bone graft substitutes), and minimally invasive instrumentation (percutaneous screws, expandable cages, specialised retractors enabling major reconstructions through small incisions).
Quality implants matter, modern instrumentation is stronger, lower profile (reducing soft tissue irritation), biocompatible, and designed based on biomechanical principles, optimising fusion success and construct stability.
Post-Operative Care:
Successful surgery requires excellent post-operative care including initial recovery in hospital (typically 1-5 days depending on procedure complexity, simple microdiscectomy might be same-day discharge; multi-level fusion requires several days hospitalisation), pain management (multimodal analgesia using combinations of medications minimising opioid requirements whilst providing adequate pain relief), early mobilisation (getting patients up and walking soon after surgery, reduces complications, improves outcomes), wound care (monitoring for infection, managing drains if placed), physiotherapy (teaching safe movement, back protection strategies, progressive mobilisation and strengthening), bracing when indicated (some procedures require post-operative bracing, rigid braces for unstable fractures or fusions, soft braces for comfort and reminder about movement precautions), and close monitoring for complications (neurological changes, infection, haematoma, cerebrospinal fluid leak).
Comprehensive Rehabilitation:
Surgery is only the beginning, rehabilitation maximises outcomes including physiotherapy (progressive strengthening, flexibility, functional training, return to activities), occupational therapy when needed (adapting activities, ergonomic advice, return to work planning), pain management (addressing post-operative pain, managing pre-existing chronic pain, reducing opioid dependence), smoking cessation support (absolutely critical for fusion patients, smoking dramatically increases fusion failure rates), weight management (reducing spinal load, improving overall health), and gradual return to normal activities (clear guidance about activity progression, when to resume driving, work, exercise, heavy lifting).
Full recovery takes months, the early phase focuses on wound healing and pain control,the intermediate phase on building strength and endurance, late phase on returning to full activities. Patients must commit to rehabilitation for optimal outcomes.
Spinal Trauma Care:
Traumatic spinal injuries, fractures, dislocations, and spinal cord injuries require urgent expert care. We provide comprehensive spinal trauma services including emergency assessment and stabilisation (high-dose steroids for acute spinal cord injury if within therapeutic window, spinal immobilisation, imaging), urgent surgical intervention when indicated (unstable fractures requiring fixation, fractures with spinal cord compression requiring decompression, fracture-dislocations), and coordinated rehabilitation (spinal cord injury rehabilitation is complex, prolonged process requiring multidisciplinary expertise).
Spinal trauma outcomes depend critically on timing; spinal cord decompression within 24 hours of injury improves neurological recovery, unstable fractures need urgent stabilisation, preventing further spinal cord injury. We provide 24/7 availability for spinal trauma, ensuring urgent cases receive immediate attention.

FAQ
Frequently Asked Questions
Common Concerns and Honest Answers
Paralysis from elective spinal surgery is rare, occurring in well under 1% of routine decompressions and fusions. Risk is higher in complex deformity correction, revision surgery, or surgery for spinal cord compression (where neurological function is already compromised). Modern techniques, meticulous surgical technique, intraoperative neuromonitoring, improved instrumentation, have dramatically reduced neurological injury risk. However, risk can never be zero, proximity to spinal cord and nerves makes spinal surgery inherently carry some neurological risk. Your surgeon discusses specific risk for your procedure.
For mechanical back pain without neurological involvement, conservative management is often appropriate, many people live with chronic back pain managed through physiotherapy, medications, activity modification, and pain management techniques. Surgery for mechanical back pain (without clear structural problem causing nerve compression or instability) has unpredictable outcomes.
However, when severe pain profoundly limits quality of life despite maximum conservative treatment, when neurological function is deteriorating (progressive weakness, cauda equina syndrome), or when structural problems exist (unstable spondylolisthesis, severe stenosis with claudication), surgery offers benefits that often outweigh risks. This is individual decision requiring careful discussion about risks, benefits, and realistic expectations.
Varies enormously by surgery and occupation:
- Microdiscectomy: 2-6 weeks for desk job, 6-12 weeks for physical labour
- Decompression: 4-8 weeks for sedentary work, 12+ weeks for physical work
- Single-level fusion: 6-12 weeks for office work, 3-6 months for labour
- Multi-level fusion or deformity: 3-6 months for any work, 6-12 months for heavy labour
- Spinal cord injury: Months to years, often unable to return to previous occupation
Your surgeon provides estimates based on your specific procedure and work demands.
Depends on procedure and surgeon preference. Simple decompressions rarely need bracing. Some surgeons prescribe soft braces after fusion for comfort and reminder about movement precautions, evidence supporting bracing is limited but many patients find braces reassuring. Traumatic injuries or highly unstable situations might require rigid bracing (TLSO, cervical collar) for 6-12 weeks ensuring stability during healing.
Yes, spinal instrumentation (screws, rods, cages) will trigger metal detectors. Carry letter from surgeon documenting hardware. Most airport security staff are familiar with spinal implants, brief explanation usually suffices. Alternatively, request manual screening.
Yes. Modern spinal implants (titanium, some stainless steel alloys) are MRI-compatible. Hardware causes artifact (image distortion around metal) but doesn't heat up or move in MRI scanner. Some very old implants might not be MRI-safe, if you have very old hardware, verify MRI safety.
Unrealistic expectation. Surgery relieves specific symptoms related to nerve compression, leg pain from disc herniation, claudication from stenosis, arm pain from cervical radiculopathy. Surgery is very effective for radicular pain (85-90% relief typically).
However, surgery is less effective for axial back pain (pain in back itself without leg pain), doesn't reverse pre-existing nerve damage (long-standing weakness or numbness might persist despite decompression), and doesn't prevent all future back pain (aging spine continues degenerating, adjacent segments might develop problems years later). Some residual discomfort, stiffness, activity-related pain is common even after successful surgery.
Goal is significant improvement, reduced pain enabling functional activities, return to work and valued activities, reduced medication dependence. Complete elimination of all back discomfort is unrealistic.
"Should I get a second opinion?" Absolutely appropriate for elective spinal surgery, surgery is significant decision with risks and substantial recovery. Second opinions provide additional perspective, confirm diagnosis and surgical plan, or present alternative approaches. Ethical surgeons support second opinions and shouldn't pressure you.
However, if multiple surgeons recommend similar surgery and you're seeking opinion telling you surgery isn't needed, recognize that you might be in denial about need for surgery rather than receiving bad advice.
Depends on condition:
- Disc herniation: 80-90% improve with conservative treatment within 3-6 months. Surgery is elective for persistent pain, not mandatory for most.
- Stenosis: Progressive condition. Symptoms gradually worsen over years. Surgery is elective for quality of life.
- Cauda equina syndrome: Emergency. Permanent bowel/bladder dysfunction and paralysis likely without urgent surgery.
- Progressive myelopathy: Progressive spinal cord damage without surgery. Irreversible neurological deterioration.
- Unstable fractures: Risk of spinal cord injury, progressive deformity without surgery.
- Deformity: Progressive worsening, respiratory compromise in severe scoliosis without surgery.
Your surgeon explains natural history, what happens without surgery, enabling informed decision-making.
Failed back surgery syndrome" describes patients with persistent or recurrent pain after spinal surgery. Occurs in 10-40% depending on definitions and patient population. Causes include wrong diagnosis, technical failures, complications, adjacent segment disease, psychological factors, unrealistic expectations, or unknown factors.
However, focusing only on failures ignores 60-90% of patients who improve significantly. Surgical outcomes depend on appropriate patient selection (operating on right conditions in right patients), realistic expectations (surgery improves specific problems, doesn't cure all back pain), optimal surgical technique, and patient factors (smoking, obesity, psychological factors, compensation issues all affect outcomes).
Your surgeon discusses realistic expectations preventing disappointment despite technically successful surgery.
Once bone graft solidifies (6-12 months), fusion is permanent, vertebrae are fused solid, won't come apart. However, hardware can fail (screws loosen, rods break) if fusion doesn't solidify (pseudarthrosis), requiring revision. Adjacent segments can degenerate causing recurrent symptoms years later. But solid fusion itself is permanent.
Fusion eliminates motion at fused levels. Single-level lumbar fusion removes approximately 5-10 degrees of motion, most people don't notice loss given remaining motion at other levels. Multi-level fusion (3+ levels) causes noticeable loss of flexibility, more difficulty bending to tie shoes, twisting to look behind whilst driving.
However, most daily activities don't require extreme spinal flexibility, most patients adapt well to fused spine, trading mobility for pain relief and stability.
