OBJECTIVE: Surgical restoration of upper extremity function in tetraplegia is acknowledged as beneficial, yet in many countries it is underused or absent. This study describes a 10-year review of a project to implement a tetraplegia upper extremity surgery service in Hungary. The main aims were to increase awareness among patients, the medical community and the public about the benefits of this rehabilitation. The process of implementing a national tetraplegia hand surgery service is described, together with a retrospective outcome study of upper extremity function after surgical reconstruction in this service.
METHODS: A total of 141 tetraplegic patients were assessed. Of these, 57 (40%) underwent a total of 126 reconstructions, including 366 procedures, between 2002 and 2012. Clinical parameters and patient-perceived results demonstrated improved functions and abilities. Considerable media attention and scientific presentations facilitated making this service permanent. In 2009, surgical rehabilitation in tetraplegia became a recognized part of the rehabilitation protocol in Hungary.
RESULTS: These results suggest that the success of starting a national tetraplegia hand service relies on convincing postoperative outcomes, patient-to-patient contacts, and co- operation between rehabilitation specialists, therapists, health authorities and surgeons.
Discussion: The leadership of dedicated hand surgeons is necessary to provide and disseminate scientific support for the concept of tetraplegia hand surgery and to stimulate interdisciplinary communication and educational programmes.

INTRODUCTION
Spinal cord injury is, at present, incurable; thus, for tetraplegic patients, arm and hand usability remains the foremost resource other than the brain in pursuit of a self-determined life (1). Reconstructive surgery of the upper extremities using tendon transfer and joint stabilizations or, more recently, nerve transfer, has become an accepted part of rehabilitation of patients with cervical spinal cord injury (2, 3). Numerous case series have demonstrated that key functions, such as elbow extension and handgrip can be restored reliably in individuals affected by traumatic or non-traumatic tetraplegia (4–11). Consequently, the mobility, spontaneity and independence of tetraplegic individuals can be markedly and persistently increased (12–14). Snoek et al. (15) reported that 77% of 565 tetraplegic patients expected to experience important or very important improvements in their quality of life if their hand function was improved. However, in many countries tetraplegia upper extremity surgery is rarely performed. For example, in the USA less than 7% of patients eligible for surgical reconstruction actually undergo these procedures (16). Multiple barriers can hinder the awareness of such upper extremity interventions, including a shortage of hand surgeons with sufficient experience, lack of information about these procedures, scepticism within patient and non-surgical communities towards surgical rehabilitation, weak interdisciplinary relationships and insufficient financial and/or social support for tetraplegic patients (16–19).
The aim of this paper is to describe the implementation of a new specialized hand surgery service for patients with tetraplegia in Hungary starting in 2002 and its evolution until the present day.
MATERIAL AND METHODS
The process of establishing a national tetraplegia hand surgery service is described (Table I, Fig. 1), including a retrospective outcome study of upper extremity function after surgical reconstruction by this service (Tables II and III). The latter comprised strength measurements of elbow extension, key pinch and grip, measurement of opening of the hand and patient-perceived outcomes according to House (7).

Multiple milestones (numbers in red) were identified during this process: 1: Securing designated beds and rehabilitation resources at regional hospital (2003). 2: Creating governing guidelines, protocols and algorithms (2004). 3: Establishing a reliable referral pattern nationally (2005). 4: Securing official status as a national unit (2006). 5: Providing continuous medical education available to surgeons and therapists (2009–2015).
Initial phase
In an attempt to create a tetraplegia upper extremity surgery service in Hungary, the authors decided to launch a project in 2001, inspired by the 7th International Conference on Surgical Rehabilitation of the Tetraplegic Upper Extremity in Bologna, Italy. The aim was to increase awareness of this therapeutic option in patients, colleagues in rehabilitation medicine, neurosurgery and orthopaedic surgery, therapists, health administration and the public.
Our first patient, a 27-year-old tetraplegic woman, presented to us in February 2002. She was categorized as OCu5(Tr+) according to the International Classification of Hand Function in Tetraplegia (ICHFT, Table II). In April 2002, a standard procedure at that time was performed on her right (dominant) hand (i.e. brachioradialis to flexor pollicis longus and extensor carpi radialis longus to flexor digitorum profundus tendon transfer together with split distal flexor pollicis longus tenodesis of the thumb interphalangeal joint and Zancolli lasso plasty) (9, 20). Following this successful surgical reconstruction, a structured project plan (roughly as described in Fig. 1) was presented to the local hospital director and city authorities. The project was initiated with their support. A large number of tetraplegic patients were invited to undergo assessment, and suitable patients were offered reconstructive upper extremity surgery. Within one year, 14 tetraplegic patients classified as OCu3–5 received surgical reconstructions. All patients considered the surgical result beneficial and recommended other tetraplegic patients to undergo assessment for the same procedures.

Increasing awareness and building networks
These initial results were presented in 2003 at 2 national meetings and 1 international congress. A website was created to promote contact between operated patients and potential candidates. It was maintained by a tetraplegic patient who had himself benefitted from reconstruction. Examinations and operations were initially coordinated by the hand surgeon. Information for potential candidates and the public was provided by the hand surgeon, satisfied patients, the hospital’s communication department and multiple media reports. A network of interested neuro-rehabilitation experts, physiotherapists and ergotherapists was established in 2004. Initially the network included 2 rehabilitation doctors, 2 hand surgeons, 2 ergotherapists, 2 physiotherapists, 1 anaesthesiologist with subspecialty in pain medicine, and 1 medical engineer working in 2 separate units and with the National Rehabilitation Centre in Budapest as the main referral unit. Acceptance of surgical rehabilitation of the paralysed upper extremity increased due to the marked objective and subjective functional gains of the operated individuals. The first author was invited to be consultant at the Hungarian National Rehabilitation Centre in 2006, and hand surgery became a recognized part of the treatment protocol in tetraplegia. The first European Tetraplegia Hand Surgery Course was given in Budapest, Hungary in March 2009.
Results of functional surgery
Both objective measurements and patient-reported outcomes according to House demonstrated substantial functional gains after surgery.
Objective outcomes
Overall, 141 tetraplegic patients were examined. Of these, 57 patients (10 females, 47 males) were treated with 126 surgical reconstructions, including 366 procedures, on 80 upper extremities (i.e. 23 bilaterally) between 2002 and 2012. Mean age at injury was 29.2 years (age range 17–56 years). The mean interval between injury and operation was 5.4 years (standard deviation 5.9) (range 1–27 years), but outcomes were not related to the delay from injury to time of surgical reconstruction. All patients sustained traumatic spinal cord injuries from level C4 to C7 and were classified as OCu1–9 and with (n = 50 arms) or without (n = 30 arms) functioning triceps according to the ICHFT (Table II). Surgical treatment included restoration of elbow extension (n = 50), active key pinch and grasp (n = 76). Elbow extension, key pinch and grip strengths were markedly improved (Table III).

The complication rate was less than 4%, and included haematoma (n = 2), wound infection (n = 2) and elbow extension deficit of 30° (n = 1).
Patient perceived outcomes
The majority of patients reported improvements in important daily activities after surgery. No patient was worse after surgery. Seventy-four percent of patients reported improvements in 1 or several of the following items: washing, brushing teeth, using utensils, dressing upper extremity, writing, wheelchair propulsion, handling small objects and opening doors. No or limited changes were reported for: dressing lower extremity, transfer to and from the car, couch, toilet and bed, and several activities that required either good shoulder muscle strength or fine motor control.
DISCUSSION
Although reconstructive upper extremity surgery in tetraplegia has been reported as highly beneficial, it is profoundly underused or not accessible even in highly developed countries (16). Starting a new national service seems a logical step, but may face numerous obstructions before being realized.
In accordance with the literature, typical barriers included scepticism regarding surgical rehabilitation from the patients, physiatrists and therapists, due to weak interdisciplinary exchange and lack of information provision to patients (17. 18). Other potential factors that may affect the start of such a service are insufficient social support for patients, questionable motivation, negative attitudes, incomplete insurance coverage or inability to accommodate tetraplegic patients (19). The crucial point was to gain the rehabilitation experts’ trust and support. Failing this initially, another option was to directly approach patients and to offer assessment as well as inform them about surgery and, in selected cases, carry out successful operations. The support of an experienced tetraplegia hand surgeon was necessary to avoid unsuccessful cases and to follow the basic rule of nil nocere (“do no harm”). Our results compared favourably with other case series (6).
Patients played a key role in the decision-making process, including the assessment of risks and benefits of upper extremity surgery. We judged it important to perform a large number of successful operations in a relatively short period of time (14 patients within the first year), create a website for patients, arrange meetings between the operated and non-operated patients, present the results at conferences, arrange lectures for doctors interested in tetraplegia rehabilitation, publish scientific articles in the field of tetraplegia hand surgery and rehabilitation and invite media. It is commonly commented that this type of medical service requires a high level of resources because of the labour-intensive and long-term care and rehabilitation needed postoperatively. While most of the caregivers agreed that this medically and socially vulnerable patient population should have access to the best treatment and care available, the infrastructural platform was a topic for disagreement and debate. In our opinion, the implementation of this type of highly specialized care should be directed and controlled by national health authorities. In retrospect, we probably would have avoided some of the above-mentioned obstacles by instituting an executive working group of experts and patients at an early stage. This would have taken into account the interests of all involved parties, governed by an independent authority and with a clear timetable to identify the “if?”, “what?” and “when?” issues. Thereafter, a strong patient perspective, together with the professional aspects, should identify the “how?” and “where?”. To avoid narrow-minded and prestige-related arguments, the patient perspective should, again, have a powerful role in the final decision. Once the decision is made, all positive forces should be aimed at making this service as successful as possible from as many aspects as possible, such as quality, patient security, accessibility, teaching and development, including continuous education. Regular site visits and outcome controls by health authorities may help to maintain the predefined standards. Since the spinal cord injured patients represent a population with special needs and care throughout life, it is recommended to establish the tetraplegia hand surgery service within, or in close proximity to, a comprehensive spinal unit.
The aim of starting a tetraplegia upper extremity surgery service in Hungary could finally be realized despite initial difficulties. Other countries may face the same problems. The collaboration of rehabilitation medicine doctors, surgeons and therapists is instrumental for success. Failing this would make the service difficult to maintain over time, especially considering the need for expeditious actions; for example, when nerve transfer surgery is indicated and should be undertaken within a relatively short time window of approximately one year after injury (2, 21–22). Reconstructive surgery should probably be started with patients from ICHFT groups 4–5, as their very low functional level can be dramatically enhanced by time-proven procedures with predictable results. However, with time, the level of sophistication of surgical expertise will expand and allow for more advanced, but yet much-needed, surgical reconstruction, such as nerve transfer combined with tendon transfers.
This review of a model process demonstrates that the implementation of a national tetraplegia hand surgery requires a target-orientated perspective and optimism, endurance, communication and time, but may be highly rewarding for both patients and caregivers and serve as a guideline for similar projects in other countries.
