open reduction

Great toe dislocation

Epidemiology

 

Uncommon

- dancers

- athletes

 

Aetiology

 

Hyperdorsiflexion of the MTPJ

 

Pathology

 

MT head dislocates plantar

- may buttonhole through capsule

- can prevent closed reduction

 

Blocks to Reduction

 

1.  Sesamoids

2.  Conjoint tendon

3.  Intersesamoid Ligament

 

Management 6 - 18 months

Two groups of dislocated hips

 

1.  Late presenters

2.  Failures of splint in those < age 6/12

 

Options

 

1.  Adductor tenotomy + closed reduction

- most surgeons will attempt this initially

- risk of AVN wilth forceful reduction / excessive abduction

 

2.  Open Reduction

- for failure of closed reduction

Definition

 

Fracture / plastic malformation of proximal ulna with dislocation of radial head

 

Xray

 

Radio-capitellar line disrupted

 

Management

Deformity

 

Varus / extension / external rotation

 

Options

 

Intertrochanteric

Base of Neck

Subcapital

 

Osteotomy

 

Valgus / flexion / internal rotation

 

Intertrochanteric / Southwick 

 

Technique

- biplanar

- valgising / flexion / internal rotation 

Background

Definition

 

Displacement of proximal femoral epiphysis in the immature hip

- due to imbalance of mechanical and endocrine factors 

 

Epidemiology

 

Age Peak Incidence : M 12-14; F 11-13; Slight downward trend due to earlier maturation of children

L hip > R

10 / 100 000

 

Bilateral SUFE

 

No endocrine abnormality

- 20% at time of of diagnosis

- another 20% during diagnosis

- up to 60% with long term follow up

Lateral condyle fractures

Epidemiology

 

Average age 6 years

 

20% distal humeral fracture

- second most common elbow fracture after supracondylar

 

Mechanism

 

Pull Off 

- more common 

- fracture begins posterolateral metaphysis

- LCL, ECRL & ECRB attached to fragment

 

Push off

- varus force to extended EJ

 

Classification

 

Management > 18 months

Dislocated Hip

 

Issue

 

Hip has been out for some time

- degree of acetabular dysplasia evident

- less time for remodelling

- increased instability if not addressed

 

Management

 

Open reduction + FDRO / Pelvic Osteotomy 

- usually perform pelvic osteotomy to correct acetabular dysplasia

- reserve FDRO for > 3 years / or if difficult reducing hip
