Special Test : Flexor tendon Examination

Soft Tissue Palpation (Posterior)
Act on the hand at the wrist joint Act on the fingers (digits 2-5)Act on the thumb
21
Soft Tissue Palpation (Anterior)
Superficial muscles of the anterior compartmentMiddle muscle of the anterior compartmentDeep muscles of the anterior compartment
23
Finkelstein’s test: Test for de Quervain’s disease

Wrist ganglion• Etiology
– Herniation of joint capsule, synovial sheath of tendon
– Contain a clear, mucinous fluid
– Most often appears on the back of the wrist
• S/S
– Symptom: occasional pain with a lump
– Sign: feel soft, rubbery or hard of cystic structure
• management:
– Pressure to break down
– Aspiration with chemical cauterization
– Surgical exision

腕隧道症候群
腕隧道症候群腕隧道症候群

(4 )(4 )
•
有腕隧道症候群的人,也許會半夜或早上醒來想要甩一甩手或手腕
•
如何診斷是腕隧道症候群?
神經傳導速率〈nerve conduction velocity〉及肌電圖〈electromyolography〉檢查,可用來做進一步的診斷

Pathoanatomic components
• Pathoanatomic components
– loss of intrinsics
• leads to loss of baseline MCP flexion and loss of IP extension
– strong extrinsic EDC
• leads to unopposed extension of the MCP joint
• remember the EDC is not a significant extensor of the PIP
joint
– most of the MCP extension forces on the terminal insertion of
the central slip come from the interosseous muscles
– strong FDP and FDS
• leads to unopposed flexion of the PIP and DIP

Hand & finger Injuries: Soft tissue
•• ContusionsContusions
•• Mallet fingerMallet finger
•• Trigger fingerTrigger finger
• Boutonniere deformity
• Swan neck deformity
• Jersey finger
54
Mallet finger
• Sometimes called baseball finger
• Jamming and avulsing the extensor tendon
• Immediately splint in extension position for 6 – 8 weeks
55
Trigger finger
• Stenosing tenosynvitis over A1 pulley area
• A lump can be felt at the base of the flexor tendon sheath
57
Swan neck deformity
• Volar plate of the PIP joint tear
• Hyperextension of PIPJ
• Splinting at 20-30 degrees of flexion for 3 weeks
Thank you
