At Zollikerberg Hospital, the motto is: precise surgery on one of the most fascinating and at the same time most complex parts of the body - the hand. Hand surgery here means not only modern technology, but above all very precise craftsmanship. This is what Dr Andreas Schierz, Head Physician and Clinic Director of Surgery, and his team stand for. They treat complaints such as carpal tunnel syndrome, rapid fingers, ganglions, hand injuries or fractures with empathy and expertise and use occupational therapy to restore the mobility of your fingers. In this interview, you can find out what is particularly important in these sensitive interventions.
The hand is one of the most complex organs in the body. What fascinates you personally about hand surgery?
It fulfils me when I can enable people with injuries or illnesses to regain good hand function. A patient who leaves my follow-up consultation satisfied gives me great pleasure.
Which illnesses or injuries do you treat most frequently - and how do they differ depending on the age group?
We often treat surgically uncomplicated illnesses or injuries. I operate on carpal tunnel syndrome very frequently. This is a constriction in one of the main nerves to the hand, which can lead to numbness in certain fingers and thus to functional limitations in the hand. This can occur in all age groups, although younger people tend to be less affected. Surgery can provide rapid relief. Bone fractures in the hand are also common. However, not all fractures require surgery; special splint treatment is often sufficient. We do not treat complex injuries or illnesses that require an artificial finger joint, for example.
Many patients are unsettled when hand surgery becomes necessary. How do you allay their fears about surgery?
I always try to explain to patients what they can expect and try not to use any technical terms so that laypeople can understand everything. I also describe the course of the operation - from preparation to discharge for most outpatient procedures. This builds trust and helps to alleviate anxiety.
What role do "minimally invasive techniques" and modern imaging play in hand surgery today?
The term "minimally invasive technique" is often only understood to mean that the skin incision is as small as possible. The scar is often the only thing you can see from the outside after an operation. However, it is also important to work as gently as possible on the inside. It helps to have a steady hand as a surgeon.
Imaging already plays an important role in diagnostics, e.g. using X-rays, MRI or ultrasound. In the case of bone fractures, computer tomography is often used to better understand the fracture pattern or to recognise the fracture in the first place. However, imaging is not necessary in all cases - the clinical examination is often sufficient for a clear diagnosis.
In addition to the operation itself, the follow-up treatment is crucial. How do you work together with physiotherapy and occupational therapy?
Depending on the procedure, ergo- or physiotherapeutic follow-up treatment can be decisive for success - be it through targeted splint treatment or movement therapy. We work closely with our therapy centre. For patients who live further away, however, we also find solutions in their region of residence. At the same time, not every diagnosis or operation requires such therapy.
Are there any typical misunderstandings or myths about hand surgery that you are often confronted with?
Many complaints can be treated with minor procedures under local anaesthetic - e.g. a "snapping finger" or, depending on the location, a ganglion (protrusion of the joint capsule) on the finger joints. A general anaesthetic is therefore not always necessary.
What are your hopes for the further development of hand surgery at Zollikerberg Hospital over the next few years?
I have been treating patients with hand complaints or injuries for over 20 years now. Dr L. Aloji, also a trauma surgeon with a great passion for hand surgery, has joined our management team to ensure that we can continue to offer hand surgery at Zollikerberg Hospital in the future, for example during absences. Together we are committed to all patients with hand problems.

Gout: recognising, preventing and treating the causes
Gout is a metabolic disorder caused by too much uric acid in the blood. Uric acid is formed from purines, which are found in many foods and in all body cells. As a rule, purines are broken down into uric acid, 80 per cent of which is excreted via the kidneys and 20 per cent via the intestines. If less uric acid is released from the body, it is deposited in the form of crystals in joints and causes inflammation.

Glaucoma - the underestimated risk to your eyesight
Glaucoma, also known as glaucoma, is one of the most common causes of irreversible vision loss worldwide. Despite its prevalence, this eye disease goes unnoticed by many sufferers for a long time, as it develops gradually and without early symptoms. This is precisely why early diagnosis and treatment is crucial in order to preserve vision and prevent blindness. In this article, we explain what exactly glaucoma is, what the risk factors are, how the diagnosis is made and what modern forms of treatment are available. We also provide valuable tips on how you can help prevent it yourself.
