About this study
Official title: Hand and Wrist Injuries in Professional Hockey Players in Sweden: A Nationwide Observational Cohort Study From the Swedish Hockey League
This study, titled Hand and Wrist Injuries in Professional Hockey Players in Sweden: A Nationwide Observational Cohort Study from the Swedish Hockey League (SHL-HITT), aims to deliver a comprehensive national overview of hand and wrist injuries among professional hockey players.
These injuries are relatively common-accounting for approximately 16% of all hockey-related injuries-and can range from minor issues to severe conditions that jeopardize player performance and careers due to prolonged absences or lasting impairment. Despite their significance, there is limited detailed knowledge regarding the specific patterns, mechanisms, and consequences of hand and wrist injuries at the elite level.

Utilizing data from a nationwide injury registry, this observational cohort study will cover three full SHL seasons: 2022/23, 2023/24, and 2024/25. The dataset is expected to include approximately 2,300 games, encompassing both regular season and playoff matches. The study will examine injury characteristics such as type (e.g., fractures, soft tissue damage), player position, in-game timing, and additional contextual factors. Statistical analyses will be conducted to identify trends, correlations, and potential risk profiles among different player groups or positions.
The findings are expected to support the development of enhanced protective equipment and targeted prevention strategies, ultimately contributing to reduced injury incidence and improved athlete health and career sustainability.
The study timeline includes preparation in late 2024, with data collection already ongoing and ethical approval obtained. The analysis will begin following the publication of the study protocol, and we aim for final publication of results in the second half of 2025.
Read the detailed description
This nationwide observational cohort study, titled Hand and Wrist Injuries in Professional Hockey Players in Sweden: A Nationwide Observational Cohort Study from the Swedish Hockey League (SHL-HITT), aims to systematically characterize the epidemiology and distribution of hand and wrist injuries among elite ice hockey players in the Swedish Hockey League (SHL). Given that upper extremity injuries constitute a significant proportion of hockey-related trauma, with approximately 16% involving the forearm, wrist, and hand, this study addresses a critical gap in the literature regarding the incidence, nature, and severity of these injuries in professional athletes. Utilizing registry data collected since the 2022/23 SHL season, including detailed player baseline characteristics, injury diagnoses classified by ICD codes, and contextual game data, the study will employ descriptive and inferential statistical analyses to elucidate patterns of fracture and soft tissue injuries. Particular emphasis will be placed on evaluating injury mechanisms relative to player position and game situations. Statistical methods will include Pearson correlation, chi-square tests, and parametric or non-parametric tests as appropriate, with significance set at p<0.05. Findings from this study are expected to contribute valuable insights for the development of evidence-based injury prevention strategies and tailored protective interventions aimed at reducing the burden of hand and wrist injuries, thereby potentially enhancing player safety and performance outcomes in professional ice hockey.

What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| SHL players with hand/wrist injuries from all games in 2022/23-2024/25 seasons | The study cohort will consist of all registered professional ice hockey players in the Swedish Hockey League (SHL) who have sustained a hand or wrist injury during official SHL games over the course of three full seasons: 2022/23, 2023/24, and 2024/25. This includes players from all 14 teams in the league. In total, the study is expected to cover approximately 2,300-2,350 games, including both regular season and playoff matches across the three seasons. All injuries recorded in the SHL's centralized medical injury registry, maintained by the Swedish Medical Association for Ice Hockey, will be included. This registry captures detailed information reported by team medical staff during each season. The cohort will include: All SHL players active during the 2022/23, 2023/24, and 2024/25 seasons. Players of all positions (forwards, defensemen, goalkeepers) and age groups. All injuries coded under relevant ICD classifications for trauma to the elbow, forearm, wrist, and han |
What is being measured
The primary outcome is the main question the study is designed to answer.
Distribution and frequency of hand and wrist injuries among professional ice hockey players in the Swedish Hockey League (SHL).
Anatomical location (e.g., wrist, hand, fingers, thumb)
Type of injury (e.g., fracture, dislocation, ligament injury, tendon rupture, contusion)
Laterality (left vs. right hand)
Measured: For the 2022/23 to the 2024/25 season.
Secondary outcomes (6)
Injury incidence by player position
forward, defenseman, goalie
Measured: For the 2022/23 to the 2024/25 season.
Time of injury occurrence
during game vs. practice; period of the game; season timing
Measured: For the 2022/23 to the 2024/25 season.
Time lost due to injury
number of games missed or duration of absence
Measured: For the 2022/23 to the 2024/25 season.
Severity of injury
The severity of the injuriy will be rated by the time to return to play in days.
Minimal (1-3 days) Mild (4-7 days) Moderate (8-28 days) Severe (>28 days)
Measured: For the 2022/23 to the 2024/25 season.
Recurrence of injury
Injuries in the same anatomical region during the study period
Measured: For the 2022/23 to the 2024/25 season.
Baseline characteristics of the cohort
Age, stick handedness
Measured: For the 2022/23 to the 2024/25 season.

Questions about this trial
What is this clinical trial studying?
An observational study of Register and Injuries, run by Dalarna County Council, Sweden at 1 site in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Distribution and frequency of hand and wrist injuries among professional ice hockey players in the Swedish Hockey League (SHL). (time frame: For the 2022/23 to the 2024/25 season.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07031869, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2026.
