SINEFIX-2022 Pilotphase

30. September 2026 aktualisiert von: BAAT Medical Products B.V.

Klinische Untersuchung vor Markteinführung Inovedis SINEFIX

Shoulder pain is one of the most commonly reported musculoskeletal complaints, which negatively affects upper limb use, night rest, daily life activities, work, sports performance and autonomy. Rotator cuff disease represents the most common cause of shoulder pain and it is responsible for up to 70% of all shoulder related visits to clinicians. Its incidence furthermore is expected to grow as the population ages. A wide range of conditions are included under the umbrella term of rotator cuff disease, including rotator cuff tendinopathy, subacromial bursal pathology, and partial-thickness or full-thickness rotator cuff tears (RCTs). The latter ones, i.e. rotator cuff tears, form the indications for which the test devices, the SINEFIX implant and instruments, are intended.

Despite the high prevalence of this condition, the pathophysiology and healing potential are not well understood, making the condition challenging to predictably treat in some patient populations. RCTs may occur in young people as a consequence of trauma (e.g. acute shoulder dislocation), however RCTs typically present in middle-aged or elderly people and cannot always be attributed to precipitating events or trauma. Instead, they can be attributed to degenerative processes, and are therefore referred to as degenerative RCTs.

For RCTs, treatment options include both surgical and non-surgical (conservative) procedures.

In this context, the SINEFIX implant and instruments were developed to treat adult patients with rotator cuff lesions of size up to 2 cm through arthroscopic reconstruction.

Sekundäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Surgery time
Zeitfenster: Immediately post procedure

The total procedure duration will be recorded as the surgery time

Immediately post procedure
Usability and workflow assessment
Zeitfenster: Immediately post procedure

Usability and workflow assessment will be evaluated after each intervention through a practitioner's questionnaire covering different aspects of the implant and instruments

Immediately post procedure
Functional and clinical outcome after rotator cuff repair
Zeitfenster: At 6 months, 1 and 2 years follow-up

Functional and clinical outcome after rotator cuff repair will be assessed using the total Constant Murley score, which ranges from 0 (worst outcome) to 100 (best outcome)

At 6 months, 1 and 2 years follow-up
Functional and clinical outcome after rotator cuff repair as compared with baseline
Zeitfenster: At 6 months, 1 and 2 years follow-up

Functional and clinical outcome after rotator cuff repair will be assessed using the change of the total Constant Murley score (range 0-100) as compared to baseline

At 6 months, 1 and 2 years follow-up
Shoulder function after rotator cuff repair (subjective evaluation)
Zeitfenster: At 10 weeks, 6, 12, and 24 months

Shoulder function after rotator cuff repair (subjective evaluation) will be assessed through the Subjective Shoulder Value (SSV) which ranges from 0% to 100% (best outcome)

At 10 weeks, 6, 12, and 24 months
Shoulder function after rotator cuff repair (physical examination-active external rotation)
Zeitfenster: At 10 weeks, 6, 12, and 24 months

Shoulder function after rotator cuff repair (physical examination) will be assessed through a physical examination with assessment of range of motion for active external rotation (range 0°-90°)
