TC(1066).(05).Orthopedics Case No 144:- Claw hand

Claw hand — সংজ্ঞা

Claw hand হলো হাতের এমন deformity যেখানে সাধারণত MCP joint hyperextension এবং PIP/DIP joint flexion হয়। সবচেয়ে classic হলো ulnar claw hand—এখানে ring finger ও little finger বেশি clawing করে, কারণ ulnar nerve palsy হলে interossei ও medial two lumbricals দুর্বল/প্যারালাইজড হয়। Cubital tunnel syndrome/ulnar nerve compression-এ ring ও little finger numbness-tingling, hand weakness, intrinsic muscle wasting এবং untreated থাকলে clawing হতে পারে।

Important clinical idea: Claw hand নিজে disease নয়; এটি একটি clinical sign/deformity। তাই treatment হলো কারণ শনাক্ত করে cause-specific management + splint + physiotherapy/hand therapy ± surgery।


১. Definition — বাংলায় core meaning

  • Claw hand = আঙুলের claw-like posture।
  • Ulnar claw = ৪র্থ ও ৫ম আঙুলে বেশি deformity।
  • Total claw hand = সব আঙুল clawing; সাধারণত combined median + ulnar nerve palsy, Volkmann ischemic contracture বা severe neuropathy-তে হতে পারে।
  • Pathophysiology:
    • Interossei ও lumbricals normally MCP flexion + IP extension করে।
    • Ulnar nerve palsy হলে এই intrinsic muscle action হারায়।
    • Extensor digitorum MCP hyperextend করে, flexor digitorum PIP/DIP flex করে → claw posture।

২. Cause — কারণগুলো বাংলায় point আকারে

A. Ulnar nerve compression / entrapment — সবচেয়ে common

  • Cubital tunnel syndrome — elbow level
    • কনুই দীর্ঘক্ষণ ভাঁজ করে রাখা।
    • কনুই টেবিলে/আর্মরেস্টে চাপ দিয়ে রাখা।
    • repeated elbow flexion-extension।
    • elbow fracture/dislocation, arthritis, bone spur, ganglion/cyst।
    • Cubital tunnel হলো ulnar nerve entrapment-এর common site; numbness/tingling সাধারণত little finger ও ring finger-এ হয়।
  • Guyon canal syndrome — wrist level
    • cyclist handlebar palsy।
    • wrist ganglion।
    • hook of hamate fracture।
    • hypothenar hammer syndrome।
    • wrist trauma।

B. Trauma / injury

  • কনুই বা কবজিতে cut injury/laceration।
  • Medial epicondyle fracture।
  • Forearm fracture।
  • Penetrating injury।
  • Iatrogenic injury after surgery/injection.

C. Leprosy / Hansen disease

  • Mycobacterium leprae peripheral nerve, বিশেষ করে ulnar nerve, median nerve, posterior tibial nerve involve করতে পারে।
  • Skin patch + sensory loss + thickened nerve থাকলে leprosy strongly suspect করতে হবে।
  • WHO leprosy guideline অনুযায়ী leprosy treatment-এ rifampicin, dapsone, clofazimine MDT regimen ব্যবহৃত হয়; PB leprosy ৬ মাস, MB leprosy ১২ মাস।

D. Metabolic / systemic neuropathy

  • Diabetes mellitus।
  • Vitamin B12 deficiency।
  • Hypothyroidism।
  • Chronic kidney disease/uremia।
  • Alcoholic neuropathy।
  • Vasculitis, rheumatoid arthritis।

E. Neurological causes / mimics

  • C8–T1 radiculopathy।
  • Lower trunk brachial plexopathy।
  • Motor neuron disease।
  • Syringomyelia।
  • Stroke/upper motor neuron lesion সাধারণ claw hand করে না, তবে hand posture abnormal হতে পারে।

F. Contracture-related clawing

  • Volkmann ischemic contracture।
  • Burns scar contracture।
  • Dupuytren contracture — true nerve palsy নয়; differential হিসেবে মনে রাখতে হবে।

৩. Symptoms — উপসর্গগুলো বাংলায় details point আকারে

A. Sensory symptoms

  • Little finger ও ring finger-এর ulnar half-এ numbness।
  • Tingling/pins and needles।

৪. Clinically diagnosis — specific clinical diagnosis

A. History নিতে হবে

  • Onset: acute trauma নাকি gradual compression?
  • Numbness কোন আঙুলে?
  • Elbow flexion করলে বাড়ে কি না?
  • Cycling/keyboard/hand tool use?
  • Diabetes, thyroid disease, CKD, B12 deficiency?
  • Skin patch/ulcer/nerve thickening — leprosy clue।
  • Previous fracture/surgery/injection?

B. Inspection

  • Ring ও little finger clawing আছে কি না।
  • Interossei wasting।
  • Hypothenar wasting।
  • First dorsal interosseous wasting।
  • Skin patch, ulcer, burn scar, trophic change।

C. Motor examination

  • Finger abduction/adduction: dorsal/palmar interossei।
  • Froment test: adductor pollicis weakness।
  • Jeanne sign: thumb MCP hyperextension with Froment।
  • Card test: fingers দিয়ে paper/card ধরে রাখতে পারে কি না।
  • Grip strength ও pinch strength।
  • Flexor carpi ulnaris ও FDP medial half test করলে high vs low ulnar lesion clue পাওয়া যায়।

D. Sensory examination

  • Little finger + ulnar half ring finger।
  • Dorsal ulnar hand sensation:
    • Dorsal ulnar sensation affected হলে lesion wrist-এর proximal হতে পারে।
    • Dorsal ulnar sensation spared কিন্তু palmar ulnar symptoms থাকলে Guyon canal lesion ভাবা যায়।
  • Two-point discrimination।
  • Monofilament test — especially leprosy/diabetic neuropathy।

E. Provocative tests

  • Tinel sign at cubital tunnel।
  • Elbow flexion test।
  • Pressure provocation test।
  • Tinel at Guyon canal।
  • Neck exam: Spurling test if C8–T1 radiculopathy suspected।

৫. Investigations — specifically কী কী করবেন

First-line

  • Nerve conduction study + EMG
    • Site localize করবে: elbow, wrist, plexus, root।
    • Severity: demyelination vs axonal loss।
    • Prognosis ও surgery decision-এ helpful।
    • Cubital tunnel diagnosis-এ clinical exam-এর সাথে nerve conduction study/ultrasound ব্যবহার করা যায়।
  • High-resolution ultrasound of ulnar nerve
    • Nerve enlargement, compression, subluxation, ganglion/cyst দেখা যায়।
    • Dynamic elbow flexion-extension evaluation করা যায়।

Cause-specific tests

  • X-ray elbow/wrist
    • Fracture, old malunion, arthritis, bone spur, hook of hamate fracture।
  • MRI elbow/wrist/cervical spine
    • Mass, ganglion, anomalous muscle, cervical radiculopathy, brachial plexus lesion সন্দেহ হলে।

  • Tendon injury/contracture।
  • Motor neuron disease।

৭. Complications — রোগের জটিলতা বাংলায়

  • Permanent nerve damage: দীর্ঘদিন nerve compression থাকলে axonal loss হয়ে recovery কমে যায়।
  • Intrinsic muscle wasting: interossei/hypothenar wasting permanent হতে পারে।
  • Fixed claw deformity: প্রথমে flexible থাকে, পরে joint contracture হয়ে fixed deformity হয়।
  • Loss of hand function: লেখা, খাওয়া, কাপড় পরা, কাজ করা কষ্টকর।
  • Neuropathic pain: burning pain, sleep disturbance।
  • Trophic ulcer: sensory loss থাকলে injury বুঝতে পারে না।
  • Secondary infection: ulcer/cut থেকে cellulitis/osteomyelitis।
  • Disability & stigma: leprosy-associated claw hand হলে social stigma ও functional disability হয়।
  • Post-surgical stiffness/scar pain: surgery হলে rehab না করলে stiffness হতে পারে।

৮. Treatment / management — guideline-based approach

A. General management

  • Cause identify করুন: compression, trauma, leprosy, diabetes, B12 deficiency।
  • Aggravating posture avoid:
    • দীর্ঘক্ষণ elbow flexion নয়।
    • elbow pressure নয়।
    • cycling হলে padded glove/handlebar modification।

  • Renal/hepatic profile দেখে dose adjust।

Progressive weakness / wasting / fixed claw

  • Early referral: orthopedic hand surgeon / plastic hand surgeon / neurology।
  • NCS/EMG।
  • Surgical decompression/nerve repair if indicated।
  • Anti-claw splint + structured hand therapy।
  • Late fixed deformity: tendon transfer consideration।

  • Acute neuritis: prednisolone specialist-supervised।
  • Ulcer care, protective footwear/hand care, disability prevention।

১১. Prevention — কীভাবে প্রতিরোধ করবেন

  • কনুই দীর্ঘসময় ভাঁজ করে রাখবেন না।
  • ফোন/ড্রাইভিং/কম্পিউটার কাজে elbow flexion posture কমাবেন।
  • কনুই টেবিলে চেপে রাখবেন না।
  • ঘুমের সময় elbow বেশি fold হলে night splint ব্যবহার।
  • Cyclist হলে padded gloves, handlebar position change।
  • Diabetes control: HbA1c target individualized।
  • Vitamin B12 deficiency screen/treat, especially metformin/PPI long-term user।
  • Leprosy early detection:
    • numb patch, nerve thickening, recurrent painless injury হলে দ্রুত পরীক্ষা।
    • household contacts screen।
  • Sensory loss থাকলে:
    • গরম জিনিস ধরার আগে test করুন।
    • protective gloves ব্যবহার।
    • ulcer হলে early wound care।
  • Hand therapy নিয়মিত করুন; splint compliance maintain করুন।
  • Trauma হলে nerve injury miss না করতে early specialist assessment।

Overview / Summary

  • Claw hand হলো intrinsic hand muscle paralysis/weakness-এর deformity, commonly ulnar nerve palsy থেকে হয়।
  • Common cause: cubital tunnel syndrome, Guyon canal compression, trauma, leprosy, diabetes/B12 deficiency।
  • Diagnosis mainly clinical + NCS/EMG; ultrasound/MRI/X-ray cause অনুযায়ী।
  • Drug দিয়ে deformity cure হয় না; drug mainly pain, neuropathic pain, inflammation, leprosy/neuritis বা deficiency treat করে।
  • Definitive management: cause treatment + splint + physiotherapy ± surgical decompression/repair/tendon transfer।

Actionable Plan / Steps

  1. Confirm deformity type: ulnar claw vs total claw vs contracture।
  2. Localize lesion: elbow, wrist, cervical root, plexus—clinical exam + NCS/EMG।
  3. Screen cause: HbA1c, B12, TSH, renal/LFT; leprosy signs থাকলে slit-skin smear/biopsy as indicated।
  4. Start conservative care: activity modification, night elbow splint, anti-claw splint, hand therapy।
  5. Symptomatic drug: paracetamol/short NSAID, neuropathic pain agent if needed, B12 only if deficient/suspected neuropathy।
  6. Leprosy হলে: WHO MDT + neuritis থাকলে steroid under specialist supervision।
  7. Urgent referral: progressive weakness, muscle wasting, severe EMG axonal loss, trauma/laceration, fixed claw, ulcer/infection।
