TC(1032).(05).Orthopedics Case No 110:- Osteomyelitis

1) Osteomyelitis Definition — সংজ্ঞা

Osteomyelitis হলো হাড় ও bone marrow-এর infection/inflammation, সাধারণত bacteria দিয়ে হয়; কখনও fungus দিয়েও হতে পারে। Infection রক্তের মাধ্যমে, কাছের infected wound/ulcer থেকে, অথবা open fracture/surgery/prosthesis-এর মাধ্যমে হাড়ে ঢুকতে পারে।

Type:

  • Acute osteomyelitis: কয়েক দিন–২ সপ্তাহের মধ্যে শুরু হয়; fever, pain, swelling বেশি থাকে।
  • Chronic osteomyelitis: মাস/বছর ধরে infection থাকে; necrotic bone, sinus tract, pus discharge হতে পারে।
  • Vertebral osteomyelitis: spine/vertebrae-তে infection; adult-দের back/neck pain দিয়ে আসতে পারে।
  • Diabetic foot osteomyelitis: diabetic foot ulcer থেকে bone infection; বাংলাদেশে খুব গুরুত্বপূর্ণ clinical scenario।

2) Causes — কারণগুলো

প্রধান organism

  • Staphylococcus aureus — সবচেয়ে common; MSSA বা MRSA দুইই হতে পারে।
  • Streptococcus species
  • Gram-negative bacteria: E. coli, Klebsiella, Pseudomonas ইত্যাদি।
  • Anaerobes: diabetic foot ulcer, pressure sore, foul-smelling wound-এ বেশি।
  • Special causes: TB, fungus, Brucella, Salmonella—বিশেষ risk factor থাকলে ভাবতে হয়।

Infection কীভাবে হাড়ে যায়

  • Bloodstream spread: pneumonia, UTI, skin infection, bacteremia থেকে রক্তের মাধ্যমে।
  • Direct inoculation: open fracture, puncture wound, surgery, orthopedic implant/pin/plate/screw।
  • Contiguous spread: diabetic foot ulcer, cellulitis, abscess, pressure sore থেকে পাশের হাড়ে ছড়ানো।

Risk factor

  • Diabetes mellitus, diabetic foot ulcer
  • Peripheral vascular disease, neuropathy
  • Chronic wound/pressure sore
  • Recent trauma/open fracture
  • Orthopedic hardware/prosthetic joint
  • IV drug use
  • Immunosuppression, kidney failure, smoking

3) Symptoms — লক্ষণগুলো

  • হাড়ে গভীর ব্যথা: affected limb/back/hip/foot-এ persistent, dull, deep pain।
  • Swelling, redness, warmth: infected জায়গা ফুলে যায়, লাল ও গরম লাগে।
  • Fever/chills/sweating: acute infection-এ বেশি।
  • Pus/discharge: wound, ulcer বা surgical site থেকে pus বের হতে পারে।
  • Movement কমে যাওয়া: joint কাছাকাছি হলে range of motion কমে।
  • Non-healing ulcer: diabetic foot বা pressure sore কয়েক সপ্তাহেও না শুকালে osteomyelitis সন্দেহ।
  • Sinus tract: chronic osteomyelitis-এ skin থেকে bone পর্যন্ত পথ তৈরি হয়ে pus drain হতে পারে।
  • Back/neck pain: vertebral osteomyelitis-এ fever বা raised ESR/CRP সহ নতুন/worsening back pain danger sign।

4) Clinical Diagnosis & Investigation — নির্দিষ্টভাবে

A) Clinically কী দেখে সন্দেহ করা হয়

  • History: diabetes, ulcer, trauma, surgery, implant, IV drug use, fever, bacteremia।
  • Examination:
    • Local tenderness over bone
    • Redness, warmth, swelling
    • Exposed bone
    • Persistent sinus tract
    • Necrotic tissue
    • Joint effusion / decreased ROM
    • Diabetic foot-এ probe-to-bone test: sterile blunt probe দিয়ে ulcer থেকে bone touch হলে osteomyelitis strongly suggestive।

B) Laboratory tests

  • CBC: WBC বাড়তে পারে, chronic হলে normal-ও হতে পারে।
  • ESR, CRP: diagnosis support করে এবং treatment response monitor করতে কাজে লাগে।
  • Blood culture × 2 sets: antibiotic শুরু করার আগে করা ভালো, বিশেষ করে fever/bacteremia থাকলে।
  • Bone biopsy + culture: definitive/gold-standard diagnosis; antibiotic sensitivity পাওয়া যায়।
  • Wound swab: superficial swab কম reliable; deep tissue/bone sample ভালো।
  • Diabetes workup: RBS/FBS/HbA1c, renal function, vascular assessment।

C) Imaging

  • X-ray: first-line; কিন্তু early disease-এ normal থাকতে পারে। Bone matrix 50–75% destroy না হলে lytic change ধরা নাও পড়তে পারে।
  • MRI with/without contrast: সবচেয়ে useful; early infection, abscess, marrow edema, extent বোঝে।
  • CT scan: sequestrum, cortical destruction, hardware থাকলে helpful; MRI contraindicated হলে।
  • Bone scan / leukocyte scan / PET/SPECT: MRI করা না গেলে বা diagnosis unclear হলে।
  • Diabetic foot osteomyelitis: initial test হিসেবে probe-to-bone + plain X-ray + ESR/CRP/PCT; doubt থাকলে MRI; culture ideally bone sample থেকে।

5) Complications — জটিলতা

  • Chronic osteomyelitis: infection পুরোপুরি clear না হলে বারবার flare-up হয়।
  • Sequestrum: infected dead bone তৈরি হয়; antibiotic সেখানে ভালোভাবে penetrate করে না।
  • Abscess / sinus tract: bone বা soft tissue-তে pus pocket; skin দিয়ে drainage হতে পারে।
  • Pathological fracture: infected bone দুর্বল হয়ে ভেঙে যেতে পারে।
  • Septic arthritis: joint-এর কাছে infection হলে joint infected হতে পারে।
  • Sepsis: infection রক্তে ছড়িয়ে জীবনঝুঁকি তৈরি করতে পারে।
  • Growth disturbance: শিশুদের growth plate আক্রান্ত হলে limb growth কমতে পারে।
  • Amputation: diabetic foot/necrosis/gangrene হলে toe/foot/limb amputation লাগতে পারে।
  • Permanent bone loss/osteonecrosis: untreated হলে bone death হতে পারে।

6) Treatment Management — overall plan

Non-pharmacological management

  • Hospital admission: fever, sepsis, diabetic foot, severe pain, spinal symptoms, neuro deficit, large ulcer/abscess থাকলে।
  • Culture আগে: stable patient হলে antibiotic শুরুর আগে blood culture ± bone biopsy culture।
  • Surgical debridement: dead bone, abscess, sinus tract, necrotic tissue, hardware infection থাকলে।
  • Drainage: abscess থাকলে drain করতে হয়।
  • Immobilization & off-loading: diabetic foot হলে pressure কমানো; splint/cast/boot।
  • Wound care: regular dressing, necrotic tissue removal, moisture balance।
  • Glycemic control: diabetes uncontrolled থাকলে cure কঠিন।
  • Vascular assessment/revascularization: PAD থাকলে vascular surgeon দরকার।
  • Follow-up: ESR/CRP trend, wound healing, pain, fever; routine follow-up MRI সবসময় লাগে না—poor response হলে লাগে।
