MSK 3 Flashcards
Temporomandibular Joint: Normal range of motion test
3 finger insert test
1
- __________ are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes.)
- Sign of ___________

Bouchard’s nodes=PIP
Osteoarthritis

2
- _________ are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes)
- Sign of ___________

- Heberden’s nodes=DIP
- Osteoarthritis

1
- It results from hyperflexion of the extensor digitorum tendon
- Injury of the extensor digitorum tendon of the fingers at the distal interphalangeal joint
- Usually occurs when a ball, while being caught, hits an outstretched finger and jams it
- Inability to extend finger

Mallet Finger
Hyperflexion at DIP (extensor digitorum tendon)

2
- Presents with flexion of the PIP and hyperextension of the DIP.
- PIP=flexion
- DIP=hyperextension
- May affect one or more fingers, including the thumb.
- Active flexion results in being “stuck” until person passively extends finger
- PIP joint will not straightened under its own power (actively) but can be straightened by the other hand (passively). In addition the end joint of the finger (DIP joint) over straightens and will not bend (flex) fully.
- Keyword: “POP”
- Generally caused by a forceful blow to the top (dorsal) side of a bent (flexed) middle joint of a finger or a deep cut.
- May also be caused by Rheumatoid arthritis

Boutonniere (“button hole”) deformity/Trigger finger

3
- Develops with hyperextension of the proximal interphalangeal (PIP) joint and flexion of the distal interphalangeal (DIP) joint.
- PIP=hyperextension
- DIP=flexion
- May affect one or more fingers but not the thumb.
- Occurs in about 50 per cent of rheumatoid arthritis (RA) cases

Swan-neck deformity

“Squeeze-Test” (MTP/MCP)
- Indicates Rheumatoid arthritis
- Positive squeeze test – where squeezing the hand across the knuckle joints is unduly painful

Signs of Rheumatoid arthritis

- grating, crackling or popping sounds and sensations experienced in the joints or a crackling sensation
- Indication of lost cartilage (sound is bone on bone)
- crepitus
- __________ and _________ will likely display crepitus
- Also common in trauma and is a common sign of ________

Identify
- condition in which the knees angle in and touch each other when the legs are straightened

Genu Valgum “knock knees”
Identify
- condition in which the knees of an affected individual are wide apart, while the ankles and feet are together when he/she stands up.
- lower leg is angled inward (medially) in relation to the thigh’s axis, giving the limb overall the appearance of an archer’s bow. Usually medial angulation of both lower limb bones (femur and tibia) is involved.

Genu Varum “Bow Legged”
- In most children under 2 years old, bowing of the legs is simply a normal variation in leg appearance. In children with physiologic genu varum, the bowing begins to slowly improve at approximately 18 months of age and continues as the child grows. By ages 3 to 4, the bowing has corrected and the legs typically have a normal appearance.
