Trauma and acute injuries to the hand and wrist

Anatomy in brief: What can be affected by injuries

27 bones, numerous small joints, strong ligaments, fine tendon gliding systems and sensitive nerve tracts come together in the hand. This density explains why even seemingly small injuries can noticeably affect function.

• Bones: Metacarpal and finger bones, radius (radius) and ulna (ulna), carpal bones.
• Joints & Cartilage: From the wrist to the base, middle and end joints of the fingers.
• Ligaments & Capsule: Stabilize every joint (e.g. ulnar collateral ligaments on the thumb).
• Tendons & Muscles: Bend and straighten the fingers; slide in tendon sheaths.
• Nerves & vessels: Provide the hand and fingers with feeling, strength and blood circulation.

Depending on the mechanism (fall, twist, cut, crush), typical structures are particularly at risk. Precise diagnostics are therefore crucial to avoid loss of function.

Frequent acute injuries to the hand and wrist

The spectrum ranges from harmless sprains to complex injuries. Below is an orientation with references to our detailed pages.

• Sprains (distortions): Overstretching of the capsule and ligaments, often after twisting or supporting.
• Capsular ligament injuries: Partial or complete tears of stabilizing ligaments, e.g. B. at the base of the finger or thumb.
• Dislocations and subluxations: Dislocations of joints, sometimes with accompanying injuries to ligaments/cartilage.
• Ski thumb (UCL rupture): tear of the ulnar collateral ligament at the base of the thumb - classic after a fall with the thumb spread apart.
• Crush injuries: effects of blunt force; Risk of swelling, compartment syndrome or nail bed injuries.
• Cut injuries: Knives, glass or tools can injure skin, tendons, nerves and vessels.

Broken bones, nerve or circulatory disorders can also occur traumatically. These are explained in the higher-level areas such as bones, nerves or blood circulation.

First aid: What you can do immediately

A prudent approach helps with acute hand injuries. The goal: relieve pain, limit swelling and prevent further damage.

In the case of amputation injuries, wrap parts cleanly in a cloth, put them in a bag and store it in the cold (ice-water mixture), do not freeze directly. Seek emergency medical attention quickly.

Warning signs: When should you seek medical advice immediately?

• Significant misalignment, visible dislocation or bony instability.
• Numbness, tingling, signs of paralysis or pale/bluish fingers.
• Severe, persistent pain or increasing swelling despite rest.
• Open injuries, deep cuts, pulsating bleeding.
• Suspect of tendon or nerve injury (finger cannot be actively bent/stretched).
• Compartment syndrome is suspected (massive pain, feeling of tension, sensory loss).
• Children, elderly people or patients on blood thinners with a fall/trauma.

Diagnostics in our practice

Targeted diagnostics are the basis for the right therapy. In Hamburg-Winterhude (Dorotheenstraße 48, 22301 Hamburg) we offer structured examinations and modern imaging.

• History: mechanism of accident, time, previous illnesses, medication (e.g. anticoagulants), tetanus protection.
• Clinical examination: inspection, palpation, stability and functional tests, testing of tendon function, sensitivity and blood circulation.
• Sonography: Dynamic assessment of ligaments, tendons and soft tissues, follow-up checks without radiation exposure.
• X-ray: standard when a fracture or dislocation is suspected.
• MRI/CT: For unclear soft tissue problems or complex fractures as indicated.
• Documentation and progress planning: Determination of protection, rails, control intervals and, if necessary, further steps.

Therapy principles: conservative first – individually tailored

Many acute hand injuries can be successfully treated with conservative measures. The aim is to restore stability and function while minimizing risks.

• Immobilization/Splint: Individually adapted splints or functional bandages depending on the injury and healing phase.
• Inflammation and pain management: cooling, elevation, if necessary anti-inflammatory medication after medical examination.
• Wound management: Aseptic care, checking for signs of infection, tetanus booster as recommended.
• Early function: Careful mobilization as soon as possible in a stable manner to avoid stiffness.
• Hand therapy/occupational therapy: Targeted training for mobility, strength, coordination and sensitivity.
• Work and sport adaptation: Temporary adjustment of loads, ergonomic aids, gradual increase in load.

Regenerative procedures such as autologous blood preparations (e.g. PRP) are selectively discussed in hand orthopedics. Use only after careful indication review, information and within the framework of the current state of evidence. Not intended for acute emergencies.

When is an operation useful or necessary?

Surgical procedures are a clear option for certain findings. The decision is made based on clinical and imaging findings as well as your personal requirements in everyday life and at work.

• Unstable or displaced fractures, dislocation fractures.
• Complete ligament ruptures with instability (e.g. ski thumb with Stener lesion).
• Severing of tendons, nerves or vessels.
• Open injuries with soft tissue damage, risk of infection or foreign bodies.
• Persistent instability or blockage despite adequate conservative therapy.
• Vascular compromise or compartment syndrome (emergency).

Even with surgical measures, structured follow-up treatment is the key to a good functional result.

Follow-up treatment and rehabilitation

The hand heals best with controlled movement. After the acute phase and stabilization, hand therapy guides you back to everyday life and sport.

• Swelling management: elevation, lymphatic drainage as indicated, elastic compression.
• Movement splints and exercise programs: Dosed mobilization to avoid adhesions and stiffness.
• Scar care: Instructions for scar mobilization after wound closure.
• Strength building: Progressive and functional, tailored to work and leisure time.
• Return-to-Work/Return-to-Sport: Individual step-by-step plans taking pain, stability and resilience into account.
• Regular checks: Adaptation of the therapy goals to the healing process and findings.

Prevention: How to prevent hand injuries

• Sports: technical training, warm-up, hand protection (e.g. gloves), safety techniques for skiing/board sports.
• Workplace: Ergonomics, safe tool guidance, protective gloves, breaks during repetitive tasks.
• Everyday life: Watch out for tripping hazards, use non-slip shoes, ladders and knives correctly.
• Training: specifically train grip strength and coordination, balance training for forearm and hand muscles.

Special situations: children, elderly and underlying diseases

Age, bone density and comorbidities influence diagnosis and therapy. In children, growth plates must be taken into account. Older people are more likely to have bony injuries and benefit from fall prevention. Diabetes, smoking or blood thinners can influence wound healing and the risk of bleeding - this is taken into account in individual planning.

Subpages at a glance: Acute hand injuries

You can find more in-depth information on our detailed pages on the most important acute injuries:

• Sprains (distortions): symptoms, PECH rule, stabilization, follow-up.
• Capsular Ligament Injuries: Diagnostic Tests, Conservative and Surgical Strategies.
• Dislocations and subluxations: reduction, splints, aftercare.
• Ski thumb (UCL rupture): Diagnosis including Stener sign, treatment options.
