Bone Infection Treatment in Mumbai (Osteomyelitis)

Our Approach In Managing Bone Infections (Osteomyelitis)

Diagnose. Eradicate. Reconstruct.

At Shree Hospitals, we combine targeted microbiological assessment with advanced orthopaedic surgical techniques to manage bone infections (osteomyelitis) in Mumbai at every stage of severity.

Osteomyelitis is one of the most challenging conditions in orthopaedic surgery; it demands the right antibiotic, delivered to the right site, for the right duration, often combined with meticulous surgical removal of all infected and dead bone tissue. Half measures invariably lead to recurrence. Our approach is thorough, evidence-based, and uncompromising.

When a patient presents with a suspected bone infection, our team immediately secures bone and tissue samples for culture and sensitivity testing before initiating antibiotics  because identifying the causative organism and its antibiotic susceptibility profile is the single most important determinant of treatment success.

Empirical antibiotics are started simultaneously to prevent further bone destruction while culture results are awaited.

• Blood cultures, wound swabs, and deep bone biopsy for organism identification and sensitivity profiling
• MRI of the affected bone — the gold standard imaging for osteomyelitis, detecting medullary involvement and soft tissue extension earlier than X-ray or CT
• Labelled white cell scan (Tc-99m HMPAO WBC scan) for chronic cases where MRI findings are equivocal
• X-rays to assess bone destruction, periosteal reaction, sequestrum, and involucrum
• CT scan for cortical bone assessment and surgical planning in chronic cases
• Inflammatory markers — ESR, CRP, PCT — for disease severity assessment and treatment response monitoring

Osteomyelitis treatment may involve identifying the infection-causing organism, surgical removal of infected or damaged bone where necessary, and an appropriate course of antibiotics. Treatment depends on the infection, test results and the patient's clinical condition.

• Patient-specific treatment plans based on infection type (acute vs. chronic), causative organism, bone involved, and extent of bone destruction
• Combined medical-surgical approach for all but the most superficial infections
• Dead space management following debridement — preventing recurrence in the surgically created cavity
• Staged bone reconstruction after infection eradication — restoring skeletal continuity and limb function
• Long-term surveillance with serial inflammatory markers and imaging to confirm cure

Our orthopaedic infection service is available 24×7 because acute osteomyelitis presenting with sepsis requires the same urgency as any other surgical emergency.

1. Advanced Diagnosis & Infection Mapping

Accurate, organism-specific diagnosis is the absolute cornerstone of osteomyelitis management. Treating bone infection empirically without culture-guided antibiotic selection results in inadequate coverage, treatment failure, and the emergence of resistant organisms. Our diagnostic protocol is systematic and uncompromising.

Microbiological:

• Deep bone biopsy under image guidance or intraoperatively — the definitive method for organism identification; surface swabs are unreliable and should not be used alone
• Extended culture incubation (14 days) for slow-growing organisms including Mycobacterium tuberculosis and Brucella
• 16S rRNA PCR for culture-negative cases and detection of organisms not grown by conventional methods
• Antibiotic susceptibility testing — MIC (Minimum Inhibitory Concentration) determination to guide antibiotic selection and dosing

Imaging:

• Plain X-rays: periosteal reaction, osteolysis, sequestrum (dead bone fragment), and involucrum (new bone formation around dead bone) — changes visible only 10–21 days after infection onset
• MRI with contrast (gadolinium): earliest imaging modality to detect medullary oedema, cortical destruction, subperiosteal abscess, and soft tissue involvement — sensitivity 90–100%
• CT scan: defines cortical destruction, sequestrum morphology, and sinus tract anatomy — essential for preoperative surgical mapping in chronic osteomyelitis
• Labelled white cell scintigraphy (WBC scan): highly specific for active infection in the presence of metalwork or prior surgery where MRI is artefact-limited

Laboratory:

• CRP, ESR, and Procalcitonin (PCT) — baseline severity and treatment response markers; normalisation confirms infection eradication
• Full blood count with differential — leucocytosis in acute haematogenous, often normal in chronic cases
• Blood cultures × 2 sets before any antibiotic administration in febrile patients
• Serology for Brucella, Salmonella, and Mycobacterium in endemic populations

2. Medical Management — IV & Oral Antibiotic Therapy

Antibiotic therapy is an essential component of osteomyelitis treatment in virtually all cases, whether used as primary management in early acute disease or as adjunctive therapy following surgical debridement. The key principles are: culture-guided selection, adequate duration, and appropriate route of administration.

Acute Haematogenous Osteomyelitis (Children):

• Empirical IV antibiotic therapy initiated immediately after blood cultures and bone aspiration — targeting Staphylococcus aureus as the most common causative organism
• Step-down to oral antibiotics after 3–7 days of IV therapy, once the patient is afebrile and CRP is falling
• Total antibiotic duration: 3–4 weeks for uncomplicated cases

MRSA coverage (vancomycin / teicoplanin) added in cases with risk factors or non-response to initial therapy

Adult Haematogenous & Contiguous Osteomyelitis:

• Prolonged IV antibiotic therapy for 4–6 weeks, guided by organism and sensitivity
• Oral step-down using highly bioavailable agents (fluoroquinolones, co-trimoxazole, linezolid, rifampicin combinations) after initial IV phase for compliant patients

Rifampicin added to the regimen for staphylococcal infections in the presence of implants — the only antibiotic proven to penetrate biofilm effectively

Chronic Osteomyelitis:

• Antibiotics alone do not cure chronic osteomyelitis — surgical debridement is mandatory
• Antibiotic therapy is used as adjunctive treatment before, during, and after surgery
• Duration: typically 6 weeks post-operatively following complete debridement
• Antibiotic-impregnated PMMA beads or calcium sulphate pellets used locally to deliver high local antibiotic concentrations directly to the infected bone site
  

Monitoring:

• Weekly CRP and ESR during treatment — falling values confirm response; rising values indicate treatment failure or re-infection
• Liver function tests and renal function monitoring during prolonged antibiotic courses
• Infectious disease physician co-management for complex, multi-drug-resistant, or atypical organisms

3. Surgical Debridement & Dead Bone Removal

Surgery is the cornerstone of treatment for chronic osteomyelitis, acute osteomyelitis with abscess, and any case unresponsive to antibiotics alone. The objective is radical excision of all infected, devitalised, and avascular tissue leaving only healthy, bleeding bone at the margins.

Sequestrectomy:

• Surgical removal of the sequestrum — the fragment of dead, avascular bone that acts as a persistent nidus of infection and cannot be reached by antibiotics or the immune system
• The surrounding involucrum (reactive new bone) is preserved where possible as it provides structural support
• Aggressive curettage of all infected granulation tissue and fibrous tissue lining the bone cavity

Saucerisation / Debridement:

• For superficial cortical osteomyelitis — the infected cortex is opened and all infected bone and soft tissue is excised until viable, bleeding bone is encountered at all margins
• The resultant cavity is irrigated copiously with saline and antibiotic solution
  

Debridement with Implant Management:

• For infection around orthopaedic implants (post-fracture fixation, joint replacement): early acute infection (<3–4 weeks) — debridement, irrigation, and implant retention if fixation remains solid; late or chronic infection — implant removal mandatory followed by staged re-implantation after infection eradication
• DAIR (Debridement, Antibiotics, Implant Retention) procedure for early periprosthetic joint infection in stable implants

Wound Management Post-Debridement:

• Wound left open or temporarily closed with vacuum-assisted closure (VAC / NPWT) to manage the dead space, remove residual contamination, and prepare the wound bed for reconstruction.
• VAC therapy changed every 3–5 days; promotes granulation tissue formation and reduces bacterial load

4. Bone Reconstruction & Dead Space Management

Aggressive debridement of chronic osteomyelitis invariably creates a bone defect sometimes massive that must be managed to prevent recurrence and restore skeletal continuity. Dead space management and bone reconstruction are the most technically demanding aspects of osteomyelitis treatment.

Local Antibiotic Delivery:

• PMMA Antibiotic Beads — Polymethylmethacrylate cement beads impregnated with tobramycin or gentamicin placed in the debridement cavity. Delivers antibiotic concentrations 200× higher than IV therapy directly to the infection site, with minimal systemic toxicity. Removed at 4–6 weeks at the time of reconstruction.
• Calcium Sulphate / Hydroxyapatite Pellets — Biodegradable local antibiotic carriers that resorb over 4–8 weeks — no second surgery for removal; simultaneously act as an osteoconductive scaffold.

Masquelet Technique (Induced Membrane):

• A two-stage procedure for large bone defects (2–25 cm) following osteomyelitis debridement
• Stage 1: A PMMA cement spacer is placed in the bone defect, inducing the formation of a biologically active, vascularised membrane around it over 4–8 weeks
• Stage 2: The spacer is removed, and the membrane — now rich in growth factors and blood supply — is filled with cancellous bone graft; the membrane acts as a bioreactor, dramatically improving graft incorporation
• Reliable for defects up to 25 cm; avoids the complexity and prolonged treatment time of Ilizarov bone transport for medium-sized defects

Ilizarov Bone Transport:

• For very large bone defects (>6 cm) following debridement, where grafting alone is insufficient
• A corticotomy (bone cut) is made proximal or distal to the defect; the bone segment is transported slowly (1 mm/day) through the defect using an external fixator ring system until it docks with the opposite end
• Simultaneously, new bone (regenerate) forms at the corticotomy site — restoring bone length naturally
• Treatment duration: 1 month per centimetre of defect — demanding for both patient and surgeon, but capable of managing defects of any size
  

Vascularised Bone Graft & Flap Reconstruction:

• For defects with poor local vascularity or failed prior grafting — vascularised fibula free flap or iliac crest graft transferred on its vascular pedicle
• Plastic surgery collaboration for simultaneous soft tissue coverage in cases with extensive skin and muscle loss

5. Rehabilitation & Long-Term Monitoring

Osteomyelitis treatment does not end at surgery or antibiotic completion long-term monitoring is essential to confirm infection eradication and detect recurrence early.

Post-Operative Care (Weeks 1–6):

• Wound care, drain management, and VAC therapy changes as scheduled
• Non-weight-bearing or protected weight-bearing depending on bone integrity and reconstruction method
• Completion of IV-to-oral antibiotic course under infectious disease physician co-management
• Weekly inflammatory marker monitoring (CRP, ESR) until normalisation

Rehabilitation Phase (Weeks 6–16):

• Progressive weight-bearing under physiotherapy supervision as bone healing is confirmed on X-ray
• Range-of-motion exercises for adjacent joints to prevent stiffness from prolonged immobilisation
• Muscle strengthening programme for the affected limb
• Nutritional support — optimising protein, vitamin D, and calcium intake to support bone healing
  

Long-Term Surveillance:

• Clinical and radiographic review at 3, 6, and 12 months post-treatment
• CRP and ESR at each visit — persistently elevated or rising values warrant further investigation
• MRI or WBC scan if clinical recurrence is suspected
• Patient education — recognising early signs of recurrence: new swelling, warmth, wound opening, or fever in a previously treated site
• Monitoring for adjacent joint involvement — osteomyelitis in growing children can affect the physis (growth plate) and cause limb length discrepancy

Our orthopaedic infection team follows every osteomyelitis patient for a minimum of 2 years post-treatment because late recurrence, though uncommon, can occur and demands prompt re-intervention.
