DR ALVIN
SHOULDER & UPPER LIMB SPECIALIST
SHOULDER REPLACEMENT
A shoulder replacement is also known as
'shoulder arthroplasty', and is an operation
that replaces the damaged joint with an implant
(also known as a 'prosthesis'). The types of
implants used can either replace part or all of
the shoulder joint.
A total shoulder replacement involves placing
an implant on both the socket side (glenoid)
and the ball side (head of the humerus).
Furthermore, the geometry of the implant used
can either be 'anatomic' which aims to closely
replicate the natural anatomy of the shoulder,
or 'reversed' which aims to compensate for
weak or damaged muscles around the shoulder.
Shoulder Rotator Cuff Repair
The rotator cuff is a collective term for the tendons which attach to the shoulder and control rotation and elevation of the arm. There are four rotator cuff tendons which attach muscles from the shoulder blade (scapula) to the upper arm bone (humerus). One or more of these tendons can tear from a sudden injury such as a fall, tackle in sport, or reaching out to grab something to prevent a fall. The tendons can also tear as a result of degeneration with age. Find out more about rotator cuff tears in this article.
VIEW MOREOrthopaedic Trauma
Dr Raymond Yu manages all general orthopaedic trauma including fractures and dislocations of the upper and lower limbs. Common traumatic injuries requiring orthopaedic specialist care include wrist fractures, scaphoid fractures, shoulder fractures, hip fractures and ankle fractures.
These injuries are unexpected and can be overwhelming for patients and their families. Dr Yu and his expert team will guide you through the rehabilitation and recovery.
Shoulder Dislocation
Shoulder instability refers to the ball of the humerus sliding off the edge of the glenoid rim. When it completely slides off, the shoulder is dislocated. When the shoulder has been dislocated once, it has a tendency to become unstable and can be easier to dislocate again.
If there are ongoing instability symptoms, or the risk of repeat dislocations is high, then surgery may be necessary to stabilise the shoulder joint.
View MoreHAND AND WRIST SURGERY
The hand is a complex and delicate mechanism
composed of many interlinked muscles, tendons,
nerves and bones. It is essential for so many
simple daily tasks and injury or disease of the
hand can be life changing.
Dr Raymond Yu treats both chronic and emergency
conditions of the hand and wrist. Chronic
conditions include nerve compression (Carpal
Tunnel Syndrome), trigger finger, Dupuytren's
contracture and arthritis. Emergency conditions
include fractures, tendon rupture and
lacerations.
My goals as a surgeon are to relieve your pain, restore your function, and return you back to doing what you love.
