Educational articles on hand and upper limb conditions
Brachial plexus injuries in children can occur during birth (obstetric brachial plexus palsy) or from trauma later in life. The brachial plexus is a network of nerves that controls movement and sensation in the shoulder, arm, and hand.
Carpal tunnel syndrome is one of the most common nerve compression disorders. Many patients wonder when conservative treatment should transition to surgical intervention.
Approximately 1–2% of babies are born with congenital hand differences. As a fellowship-trained pediatric hand surgeon, I've treated hundreds of children with these conditions.
Scaphoid fractures are the most commonly fractured carpal bone, yet they're often missed on initial X-rays. This can lead to serious complications if left untreated.
Post-operative hand therapy is not just recommended — it's essential for optimal recovery. As a surgeon who has worked with hand therapists worldwide, I cannot overstate its importance.
Trigger finger (stenosing tenosynovitis) affects millions of people worldwide. While often dismissed as a minor nuisance, it can significantly impact quality of life.
Microsurgery has revolutionized hand surgery, enabling us to reattach severed digits, transfer tissue, and reconstruct complex injuries with remarkable precision.
Despite its name, tennis elbow (lateral epicondylitis) affects far more non-tennis players than athletes. It's one of the most common overuse injuries we treat.

Comprehensive arthroscopic and reconstructive shoulder care
Dr. Kannan Kumar completed a dedicated Clinical Fellowship in Shoulder and Elbow Surgery at the National University Hospital, Singapore — one of Asia's leading centres for shoulder surgery. This training, combined with his orthopaedic residency and subsequent surgical experience, gives him the expertise to manage the full spectrum of shoulder conditions, from common sports injuries to complex reconstructive procedures.
The shoulder is the most mobile joint in the body — and that mobility comes at the cost of stability. When the shoulder fails, it affects almost every aspect of daily life. Our approach combines accurate diagnosis, tailored conservative management, and — when needed — precise surgical intervention to restore function and relieve pain.
Keyhole surgery using a tiny camera and instruments to diagnose and treat shoulder problems — smaller incisions, less pain, faster recovery than open surgery.
For patients with recurrent shoulder dislocations, Bankart's repair reattaches the torn labrum to restore stability. Usually performed arthroscopically.
The rotator cuff is a group of four muscles and tendons that stabilise the shoulder. Tears — from injury or wear — cause pain and weakness that often requires surgical repair.
When the shoulder joint is severely damaged by arthritis or fracture, joint replacement restores pain-free movement and function.
Shoulder impingement is one of the most common causes of shoulder pain, especially with overhead activities. AC joint problems are common after falls and contact sports.
Adhesive capsulitis (frozen shoulder) causes progressive stiffness and pain. Most cases resolve with treatment; resistant cases benefit from arthroscopic capsular release.
Shoulder pain lasting more than 2–4 weeks, especially pain that wakes you at night or is present at rest
Difficulty lifting your arm, carrying objects, or reaching overhead — suggests rotator cuff involvement
Shoulder "giving way," slipping, or a history of dislocation — even if it went back in on its own
Progressively worsening stiffness making it hard to reach behind your back or above your head — classic frozen shoulder
Injury during cricket, badminton, swimming, or any throwing/overhead sport that hasn't settled with rest
Pain, deformity, or swelling after a fall or direct blow to the shoulder — fractures and separations need prompt assessment
Clinical examination combined with imaging — X-ray, ultrasound, or MRI — to precisely identify the cause of your pain before any treatment decision is made.
Physiotherapy, activity modification, anti-inflammatory medication, and corticosteroid injections resolve the majority of shoulder conditions without surgery.
When surgery is needed, we favour arthroscopic (keyhole) techniques wherever possible — less pain, smaller scars, faster return to daily life and sport.
