Paronychia is skin around nail plate
Eponychia is skin covering base of nail plate
1. Due to foreign material between nail plate and paronychium
2. By hang nail traumatising paronychium
Acute
- typically polymicrobial
- aerobes and anaerobes
Massive tear
1. > 5cm
- retracted to humerus / glenoid margin
2. At least 2 complete tendons
- lose SS / IS or SS / SC
Intra-articular proximal ulna fracture
Articulates with trochlea
- may have a central bare area
Triceps insertion
- via broad aponeurosis which blends with anconeus and CEO
Undisplaced fracture
- need to ensure triceps mechanism is intact
Osteochondritis Dissecans
- separation of avascular fragment of bone & cartilage
M : F = 2:1
Mean age 18 years
- can present as young as 9
4:1000
Round or "D" shaped rather than crescenteric meniscus
- occupies > 70% of tibial surface
- 90% occur on lateral side
Uncommon
- 1:100
- usually presents in children & adolescents
The perpendicular distance from the centre of the femoral head to the long axis of the femur
Harris 1992
- aim for supra-physiologic offset
- avoid making offset less than original at all costs & makes longer if possible
Soft tissue balancing equals restoring femoral offset
1. Abductor lurch / Trendelenburg gait
Migration of the femoral head past the medial wall of the acetabulum / ilioischial line
Centre edge angle > 40o
Primary
Otto's Disease
- bilateral in one third
- middle aged females
- pain & decreased ROM early
- coxa vara & OA common
- ? causally related to osteomalacia
Extraskeletal bone formation in periarticular tissues
- HA crystals within osteoid matrix
Different to calcification
- osteoid matrix laid down
1. Myositis Ossificans
- post traumatic
Any act or failure to act that
- results in or potentially results in harm / death / physical / emotional / sexual abuse
- by a parent or caretaker who is responsible for the child
Neglect
Physical (punch / kick / bite / burn / shake)
Sexual
Emotional
