Study Notes
Overview of Lower Limb Biomechanics
- Examination of lower extremity conditions and their management.
- Interconnection between CCHB421 (conditions) and CPPR421 (management).
Conditions of the Lower Limb
- Key condition elements include:
- Definition
- Clinical presentation
- Diagnostic criteria
- Orthopedic tests
- Differential diagnoses
- Pathogenesis
- Mechanism of injury
- Prognosis
- Compensatory mechanisms
- Related conditions
Treatment Approaches
- Treatment techniques encompass:
- Manipulation (spinal, sacroiliac, extremity)
- Dry needling (focus on muscles, tendons, bursae)
- Soft tissue therapy (massage, cross friction)
- Electrotherapy (ultrasound, IFC, TENS, shockwave)
- Strapping (rigid, Kinesio-taping)
- Bracing/orthotics
- Referral to specialists (orthopedic surgeons, physiotherapists)
Conditions of the Hip
- Common issues include:
- Osteoarthritis of the hip
- Femoral acetabular impingement syndrome
- Trochanteric bursitis
- Slipped femoral epiphysis
Conditions of the Thigh/Upper Leg
- Notable conditions consist of:
- Hamstring strain/muscle tear
- Hamstring tendonitis
- Ischiogluteal bursitis
- Quadriceps muscle strain
- Adductor muscle strain
- Iliotibial band syndrome
- Acute compartment syndrome
Knee Conditions
- Common knee issues include:
- Osteoarthritis of the knee
- Patella femoral pain syndrome
- Chondromalacia patella
- Medial and lateral meniscus injuries
- Ligament injuries (medial, lateral collateral ligaments, anterior and posterior cruciate ligaments)
- Osteochondritis dissecans
- Patella dislocation
- Plica syndrome
- Superior tibiofibular joint dysfunction
Conditions of the Lower Leg
- Significant conditions are:
- Medial tibial stress syndrome (shin splints)
- Compartment syndrome
- Calcaneal/Achilles tendonitis
- Calcaneal/Achilles tendon rupture
- Stress fractures
Ankle/Foot Conditions
- Key issues include:
- Sprained ankle
- Heel spurs
- Fat pad syndrome
- Plantar fasciitis
- Pes planus (flat foot)
- Pes cavus (high arch)
- Cuboid syndrome
- Medial tarsal tunnel syndrome
- Morton's neuroma
- Sesamoiditis
- Metatarsalgia
- Hallux valgus and hallux rigidus
- Tendonitis
Lower Limb Kinematic Chain
- Kinetic chains comprise a series of joints forming a complex motor unit.
- Each segment (foot, leg, thigh, pelvis) serves as a solid link; key joints include subtalar, ankle, knee, and hip.
- Open kinematic chain: free terminal movement (upper limb).
- Closed kinematic chain: fixed terminal movement (lower limb during weight bearing).
- Complex interaction among muscles and joints leads to compensatory mechanisms.
Importance of Anatomy in Treatment
- Understanding lower limb anatomy aids in:
- Grasping the conditions affecting the limb
- Preventing complications
- Addressing the root cause of issues
The Hip Joint
- Serves as a crucial link between trunk and lower limb, facilitating weight transfer and stability.
- Normal anatomy includes:
- Head of the femur articulating with acetabulum of the pelvis.
- Functions of the acetabular labrum:
- Enhances joint stability, increasing containment of the femoral head.
- Acts as a shock absorber and lubricant.
- Distributes pressure, enhancing load distribution and joint stability.
