TC(1024).(05).Orthopedics Case No 102:- Osteochondroma

Osteochondroma — বাংলায় সম্পূর্ণ Clinical Overview

Important: Osteochondroma হলো benign bone tumour। ওষুধ দিয়ে osteochondroma ছোট বা ভালো হয় না। ওষুধ দেওয়া হয় শুধু ব্যথা, inflammation, bursitis, nerve irritation অথবা surgery/post-operative pain control করার জন্য। Definitive management হলো observation অথবা surgical excision। AAOS অনুযায়ী অধিকাংশ osteochondroma childhood/adolescence-এ হয় এবং asymptomatic হলে শুধু monitoring যথেষ্ট হতে পারে।

1. Definition / সংজ্ঞা

Osteochondroma হলো হাড়ের বাইরের surface থেকে বের হওয়া cartilage-capped bony projection—মানে হাড়ের উপর অতিরিক্ত হাড়ের মতো growth, যার মাথায় cartilage cap থাকে। এটি সবচেয়ে common benign bone tumour। এটি সাধারণত long bone-এর metaphysis অংশে হয়, যেমন distal femur, proximal tibia, proximal humerus।

সহজ ভাষায়

হাড়ের পাশে “হাড়ের মতো শক্ত গুটি/বাড়তি অংশ” তৈরি হয়, যা সাধারণত cancer নয়।

2. Cause / Etiology — কারণগুলো

  • Growth plate abnormality:
    শিশু-কিশোর বয়সে bone growth plate থেকে cartilage ভুল দিকে বের হয়ে হাড়ের surface-এ growth তৈরি করে।
  • Solitary osteochondroma:
    বেশিরভাগ ক্ষেত্রে একটাই lesion থাকে। Updated review অনুযায়ী প্রায় 85% solitary, আর প্রায় 15% hereditary multiple exostoses/HME-এর সাথে থাকে।
  • Hereditary Multiple Exostoses / HME:
    অনেকগুলো osteochondroma থাকলে genetic কারণ থাকতে পারে। GeneReviews অনুযায়ী HME সাধারণত EXT1/EXT2 gene mutation এবং autosomal dominant inheritance-এর সাথে সম্পর্কিত।
  • Family history:
    বাবা/মা/ভাই-বোনের একই ধরনের multiple bony swelling থাকলে hereditary cause সন্দেহ করতে হবে।
  • Radiation exposure / previous trauma:
    Rare association থাকতে পারে, কিন্তু routine clinical cause হিসেবে প্রধান নয়।

3. Symptoms / Clinical Features — লক্ষণগুলো

A. Common symptoms

  • Hard, painless lump:
    হাঁটুর আশেপাশে, কাঁধে, হাতে বা পায়ে শক্ত গুটি দেখা যায়। সাধারণত ব্যথাহীন।
  • Slow growth:
    শিশুকালে lesion বড় হতে পারে, কিন্তু skeletal maturity/বয়ঃসন্ধির পর সাধারণত আর বাড়ে না। Adult age-এ নতুন করে বাড়তে থাকলে red flag।
  • Pain or tenderness:
    pain হতে পারে যদি tumour muscle/tendon/nerve/vessel-এ চাপ দেয়, fracture হয়, অথবা bursa তৈরি হয়।
  • Movement limitation:
    joint-এর কাছে lesion হলে হাঁটা, দৌড়ানো, knee bending, shoulder movement কমে যেতে পারে।
  • Cosmetic deformity:
    বাইরে থেকে abnormal swelling দেখা যায়, patient cosmetic concern নিয়ে আসে।

B. Neurovascular symptoms

  • Nerve compression:
    ঝিনঝিনি, অবশ ভাব, numbness, weakness, radiating pain।
  • Vessel compression:
    limb ঠান্ডা লাগা, swelling, pulse কমে যাওয়া, colour change—এগুলো urgent sign।

C. Multiple osteochondroma হলে

  • limb deformity
  • short stature
  • limb length discrepancy
  • forearm/ankle/knee deformity
  • repeated pain or functional disability

D. Red flag symptoms — জরুরি referral দরকার

  • adult age-এ lesion দ্রুত বড় হওয়া
  • rest pain/night pain
  • নতুন severe pain
  • neurological deficit
  • vascular symptoms
  • pelvis/scapula/spine lesion
  • cartilage cap adult-এ >2 cm হলে malignant transformation সন্দেহ করা হয়। Updated review-এ adult cap >2 cm এবং children-এ >3 cm concerning হিসেবে উল্লেখ আছে।

4. Clinical Diagnosis — clinically কীভাবে diagnosis করবেন

History

  • বয়স: সাধারণত childhood/adolescence
  • onset: কতদিন ধরে swelling
  • growth pattern: বাড়ছে কি না
  • pain: activity pain, night pain, rest pain
  • family history: multiple exostosis আছে কি না
  • neurological symptoms: numbness/weakness
  • vascular symptoms: cold limb, swelling, pulse problem
  • cosmetic/functional limitation

Physical examination

  • Inspection: location, size, deformity, skin change
  • Palpation: hard bony swelling, fixed to underlying bone
  • Movement: nearby joint ROM check
  • Neurovascular exam: sensation, motor power, distal pulse, capillary refill
  • Multiple lesion screening: both limbs, scapula, pelvis area clinically check
  • Limb length/deformity assessment

5. Investigations — specific test list

1. X-ray — first-line investigation

AP and lateral X-ray of affected bone/joint।
Typical finding:

  • sessile বা pedunculated bony projection
  • lesion-এর cortex এবং medullary cavity parent bone-এর সাথে continuous থাকে
    Radiograph দিয়েই অধিকাংশ diagnosis করা যায়।

2. MRI — কখন করবেন

MRI দরকার যদি:

  • pain থাকে
  • adult age-এ lesion বাড়ে
  • malignant transformation সন্দেহ
  • cartilage cap thickness measure করতে হয়
  • spine/pelvis/scapula lesion
  • neurovascular compression suspect
  • surgery planning দরকার

3. CT scan

CT useful:

  • pelvis, spine, scapula, rib lesion
  • complex anatomy
  • surgical planning
  • cortical/medullary continuity better define করতে

4. Ultrasound

  • superficial cartilage cap assess
  • bursa/bursitis detect
  • vascular relation screening

5. Biopsy

Routine osteochondroma-তে biopsy লাগে না।
Biopsy করা হয় যদি imaging-এ malignant transformation/chondrosarcoma সন্দেহ থাকে। Biopsy preferably orthopaedic oncology setup-এ করা উচিত।

6. Genetic testing

Multiple lesions + family history থাকলে EXT1/EXT2 genetic testing consider করা যায়।

7. Blood tests

CBC, ESR, CRP osteochondroma diagnose করে না। এগুলো infection, inflammatory disease, malignancy differential exclude করতে সহায়ক হতে পারে।

6. Differential Diagnosis

  • Enchondroma
  • Osteosarcoma
  • Chondrosarcoma
  • Parosteal osteosarcoma
  • Myositis ossificans
  • Bony spur / exostosis
  • Bone cyst / fibrous dysplasia
  • Bursitis or soft-tissue swelling overlying bone

7. Complications — রোগের জটিলতা

  • Fracture:
    pedunculated osteochondroma-র stalk ভেঙে ব্যথা হতে পারে।
  • Bursitis:
    lesion-এর উপর friction হলে fluid sac/bursa তৈরি হয়ে ব্যথা ও swelling হয়।
  • Nerve compression:
    peroneal nerve বা অন্য nerve চাপ খেলে numbness, tingling, weakness হতে পারে।
  • Vascular compression:
    artery/vein চাপ খেলে limb swelling, coldness, pseudoaneurysm, thrombosis হতে পারে।
  • Skeletal deformity:
    multiple hereditary exostoses-এ limb deformity, short stature, limb length discrepancy হতে পারে।
  • Joint movement restriction:
    joint-এর কাছে হলে movement কমে যায়।
  • Malignant transformation:
    সবচেয়ে feared complication হলো secondary chondrosarcoma। Solitary osteochondroma-তে risk প্রায় 1% বলা হয়; HME-তে risk বেশি, বিভিন্ন review-এ প্রায় 2–10% পর্যন্ত উল্লেখ আছে।

8. Management / Treatment

A. Asymptomatic osteochondroma

  • reassurance
  • periodic clinical follow-up
  • X-ray follow-up if lesion growing/symptomatic
  • patient education: red flag symptoms জানানো

B. Symptomatic but benign lesion

  • activity modification
  • local protection/padding
  • analgesic/NSAID short course
  • physiotherapy if joint stiffness
  • avoid aggressive massage/pressure over lump

C. Surgical treatment — definitive

Indications for excision

  • persistent pain
  • neurovascular compression
  • restricted joint movement
  • recurrent bursitis
  • fracture of stalk
  • deformity/cosmetic concern
  • adult age-এ growth
  • cartilage cap thickening
  • malignant transformation suspicion

Procedure

  • complete excision of bony stalk/base
  • cartilage cap ও perichondrium complete remove করা
  • incomplete excision হলে recurrence হতে পারে
    Updated review অনুযায়ী complete resection হলে recurrence usually low, <2% reported.

11. Prevention — কীভাবে prevent করবেন

Osteochondroma পুরোপুরি prevent করার proven method নেই, কারণ এটি developmental/genetic lesion।

Practical prevention of complications

  • lesion বাড়ছে কি না follow-up করা
  • adult age-এ growth হলে দ্রুত orthopaedic surgeon দেখানো
  • painful lesion ignore না করা
  • nerve/vascular symptoms হলে urgent referral
  • repeated trauma/pressure এড়িয়ে চলা
  • multiple lesions থাকলে family screening/genetic counselling
  • child patient হলে growth completion পর্যন্ত monitoring
  • unnecessary massage, forceful manipulation, local steroid injection avoid
  • নিজে নিজে NSAID/antibiotic দীর্ঘদিন খাওয়া যাবে না

12. Overview / Summary

Osteochondroma হলো benign cartilage-capped bony tumour। বেশিরভাগ ক্ষেত্রে painless hard swelling হিসেবে আসে এবং X-ray দিয়ে diagnosis করা যায়। Pain, rapid growth after maturity, neurovascular symptoms, cartilage cap thickening—এসব malignant transformation বা complication-এর red flag। Asymptomatic lesion observe করা যায়; symptomatic, deforming, compressive বা suspicious lesion হলে complete surgical excision treatment of choice।

13. Actionable Plan / Steps

  1. Affected area X-ray AP/Lateral করুন।
  2. Pain/growth/neurological sign থাকলে MRI করুন।
  3. Multiple lesions/family history থাকলে HME evaluation + genetic counselling consider করুন।
  4. Mild pain হলে paracetamol; inflammatory pain হলে short NSAID + gastric protection if needed।
  5. Adult age-এ rapid growth/night pain/cartilage cap >2 cm হলে orthopaedic oncology referral।
  6. Surgery হলে antibiotic prophylaxis hospital protocol অনুযায়ী; outpatient antibiotic নয়।
