Overuse Conditions
&
Fractures
Today’s Objectives
• To describe the distinguishing factors of
overuse conditions
• To discuss the common overuse conditions
• To describe the mechanism of common
overuse conditions
• To identify fracture classification schemes

Causes of Overuse
Conditions
• Intrinsic
1. Poor flexibility
2. Weakness (inadequate
conditioning or rehabilitation)
3. Alignment (structure)

Causes of Overuse
Conditions
• Extrinsic
1. Training errors
2. Equipment
3. Technique (skill mechanics)

Common Overuse
Conditions
• Tendinitis
• Bursitis
• Synovitis

5
Tendinitis
• Definition
• Review tendon structure
1. Strong, dense connective tissue
2. Callagenous tissue
• Fatigues w/repetitive loading
• Occurs at skeletal connection site

6
Tendinitis
• S/Sx
1. Insidious onset
2. Progression of condition
3. ?’s - changes in extrinsic factors
4. ?’s - activity that causes pain
5. Swelling, redness, warmth
6. Tenderness
7. Crepitus

Bursitis
• S/Sx
1. Insidious or acute onset
2. Vague Sx (local at onset)
3. Deep tenderness
4. ROM
5. Night pain

Bursitis
• Common sites
1. Lower
extremity activities
2. Upper
extremity activities

11
Capsular Synovitis
• Definition
• Synovial membrane
• Sx similar to bursitis,
but more diffuse
3/23/2016
12
Capsular Synovitis
• S/Sx
1. Insidious, subsequent joint injury
2. Pain throughout joint, even at rest
3. Redness, warmth, swelling
4. Guarding
5. NO specific area of tenderness
6. ROM limited

Fracture Classifications
• Factors: 1. Location relative to rest of bone
2. Shape, direction & magnitude
3. Duration of onset
• Lay terms/names

Fracture Classifications
Location
1. Diaphyseal (diaphysis)
2. Epiphyseal (epiphyseal line)
3. Articular fractures (articular cartilage)
