E.1.1.1 | Medical condition in easily understood language |
Sternocostoclavicular Hyperostosis is a chronic bone disorder of the anterior chest region, in which inflammation within the bone leads to pain and compromised shoulder function. |
Sternocostoclaviculaire hyperosteose is een chronische botaandoening van de borstkas, waarbij een ontsteking in het bot pijn en verminderde schouderfunctie veroorzaakt. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective to demonstrate that in SCCH patients with pain 3-monthly treatment with pamidronate will result in a significant decrease inmaximum pain score (measured by BPI) as compared to placebo.
|
Het primaire doel van het onderzoek is aan te tonen dat in SCCH patienten met pijn 3-maandelijkse behandeling met pamidronaat een significante verlaging in maximum pijnscore, gemeten met BPI, teweegbrengt in vergelijking met placebo. |
|
E.2.2 | Secondary objectives of the trial |
• To study the number of patients with mild pain (maximal pain 4 or lower) after 3-monthly treatment with pamidronate
• To study the number of patients with 50% reduction in maximal pain (VAS score in BPI)
• To study change in shoulder rating questionnaire (SRQ) and facets of Shoulder function assessment (SFA) score and range of motion
• To study improvement in general health as measured with Short Form Health Survey (Sf-36), work activity score, and physical activity International Physical Activity Questionnaire (IPAQ, short form, previous 7 days)
• To investigate partner burden
• To study a change in standard dose of analgesics
• Evaluation of confounding factors for outcome of treatment
• Significant alteration of inflammation and quantifiable decrease in Na18F-PET/CT tracer uptake of SCCH lesions
• Evaluation of a possible neuropathic component of the reported pain (pain detect)
• To evaluate cost-effectiveness of therapy in an economic evaluation |
• Onderzoeken hoeveel patienten resteren met milde pijn (maximale pijn op BPI van 4 of lager) na 3 maandelijkse behandeling met pamidronaat
• Onderzoeken hoeveel patienten 50% reductie van maximale pijn op BPI bereiken
• De verandering in shoulder rating questionnaire (SRQ) en facetten van de Shoulder function assessment (SFA) bestuderen, en range of motion
• De verbetering in algemene gezondheid bestuderen, gemeten met Short Form Health Survey, work activity score, and physical activity International Physical Activity Questionnaire
• Belasting voor de mantelzorger te evalueren
• De verandering in dosering van analgetica
• Evalueren van confounders voor de uitkomstmaten
• Het bestuderen van significante veranderingen wat betreft inflammatie en kwantificeerbare vermindering van tracer uptake op Na18F-PET/CT in SCCH lesies
• Evaluatie van een mogelijke neuropathische component van de pijn
• De kosten-effectiviteit analyseren met behulp van een economische analyse |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Adult patients (> 18 years of age) with an established diagnosis of SCCH based on clinical and radiologic features and increased radioactive tracer uptake on 99mTc scan with a reported maximum pain score of 6/10 or higher, and no treatment with bisphosphonates for the previous 6 months, and willing to participate. |
Volwassen patienten (18 jaar of ouder) met de diagnose SCCH op basis van de klinische en radiologische kenmerken en verhoogde tracer uptake op 99mTc scan, met een maximale pijnscore 6 of meer uit 10, en niet behandeld met bisfosfonaten in de voorafgaande 6 maanden. |
|
E.4 | Principal exclusion criteria |
Patients who are under 18 years of age will be excluded. Active pregnancy wish, pregnancy or nursing are exclusion criteria. Patients with generalized pain without SCCH related pain are excluded. Bisphosphonate use during previous 6 months before study entry, bisphosphonate allergy, estimated glomerular filtration rate < 30 ml/min, uncontrolled endocrine abnormalities, and active cancer treatment are exclusion criteria. Patients will not be included in the study in case of language barrier, severe co-morbidity, including poor mobility and other causes preventing attendance for control visits, as are mentally disabled patients. In case of poor dental hygiene or inadequate dental care, patients will only be enrolled after oral maxillary surgeon consultation. |
Patienten onder de 18 jaar worden geexcludeerd. Actieve zwangerschapswens, zwangerschap of borstvoeding zijn exclusiecriteria. Patiënten met gegeneraliseerde pijn zonder SCCH gerelateerde pijnklachten worden geexcludeerd. Andere exclusiecriteria: gebruik van bisfosfonaten in de 6 maanden voorafgaande aan start van de studie, allergie voor bisfosfonaten, geschatte klaring < 30 ml/min, niet-gecontroleerde endocriene ziekten, actieve kankerbehandeling, ernstige taalbarriere, ernstige co-morbiditeit inclusief slechte mobiliteit of mentale retardatie. In geval van slechte mondhygiëne inclusie is alleen toegestaan na akkoord van een kaakchirurg. |
