About this study

Official title: Evaluation of Clinical and Radiographic Results After Surgical Treatment With Implant-free Allograft for Anterior Shoulder Dislocation: Pilot Study

The purpose of this study is to evaluate the clinical and radiographic results after surgical treatment with implant-free allograft in the treatment of Anterior Shoulder Dislocation and to assess the safety of the surgery.

Read the detailed description

Patients will be informed about the study and potential risks. All patients giving written informed consent will undergo a screening visit to assess the eligibility criteria.

Patients who meet the eligibility requirements will perform a pre-treatment visit in order to assess their healthy state. Also, patients will undergo to the radiographic visit (RX and TX) as request by clinical practice.

All the patients will be treated with arthrotomy mini-open technique with bone allograft at the site of the shoulder lesion.

After surgery all the patients will be followed up to 24 months through clinical and radiographic visits.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from Baseline in DASH score at 24th months

    The Disabilities of the Arm, Shoulder and Hand (DASH) Score is a 30-item self-reported questionnaire in which the response options are presented as 5-point Likert scales. Scores range from 0 (no disability) to 100 (most severe disability). This score was designed be useful in patients with any musculoskeletal disorder of the upper limb.

    Measured: 24 months

Secondary outcomes (6)
  1. Change from baseline in DASH score

    The Disabilities of the Arm, Shoulder and Hand (DASH) Score is a 30-item self-reported questionnaire in which the response options are presented as 5-point Likert scales. Scores range from 0 (no disability) to 100 (most severe disability). This score was designed be useful in patients with any musculoskeletal disorder of the upper limb.

    Measured: Baseline, 1, 3, 6, and 12 months

  2. Change from Baseline in Constant score

    The Constant score contains both physician-completed and patient-reported portions. The four domains include pain (15 possible points), activities of daily living (20 possible points), mobility (40 possible points), and strength (25 possible points). Scores range from 0 points (most disability) to 100 points (least disability).

    Measured: Baseline, 1, 3, 6, 12 and 24 months

  3. Change from Baseline in Rowe score

    The Rowe score is a 3-item physician completed instrument. Its questions address the categories of shoulder stability, motion, and function. Scores range from 0 to 100 with a score of 90-100 points indicating an excellent evaluation, 75-89 points indicating a good evaluation, 51-74 points indicating a fair evaluation, and 0-50 points indicating a poor evaluation.

    Measured: Baseline, 1, 3, 6, 12 and 24 months

  4. Change from Baseline in EQ-5D-3L (EuroQoL) CurrentHealthAssessment:

    EQ-5D is a standardized instrument for measuring generic health status. The classification system defines health in five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each dimension with three levels ("no problems" [level 1], "some problems" [level 2], and "extreme problems" [level 3]), resulting in a total of 243 (3^5) health states. The 3L classification system defined the 243 health states by combining different levels from each dimension, with 11111 and 33333 representing full health and worst health, respectively.

    Measured: Baseline, 1, 3, 6, 12 and 24 months

  5. Evaluation of the grade of the Shoulder Osteoarthritis through Kellgren-Lawrence scoring

    The Kellgren and Lawrence system is a common method of classifying the severity of osteoarthritis (OA).

    The K-L system defines OA in 5 grades:

    grade 0 (none): definite absence of x-ray changes of osteoarthritis grade 1 (doubtful): doubtful joint space narrowing and possible osteophytic lipping grade 2 (minimal): definite osteophytes and possible joint space narrowing grade 3 (moderate): moderate multiple osteophytes, definite narrowing of joint space and some sclerosis and possible deformity of bone ends grade 4 (severe): large osteophytes, marked narrowing of joint space, severe sclerosis and definite deformity of bone ends.

    Measured: 24 months

  6. Evaluation of the Allograft integration

    Radiographic signs of allograft integration through the CT-dual energy instrument at 6 and 24 month post treatment

    Measured: 6 and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing allograft fixation in people with Anterior Shoulder Dislocation and Bone Defects, run by Istituto Ortopedico Rizzoli at 1 site in Italy.

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 1 inclusion and 2 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 22 May 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 Italy. 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?

Change from Baseline in DASH score at 24th months (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 May 2026.
