Brief Summary
Calcific tendinitis of the shoulder is among the frequently encountered shoulder problems. Conservative treatment is often preferred for its management. Persistent pain, impingement symptoms due to large calcific deposits, and extension into the bone are indications for surgical intervention. Although many classification methods for calcific tendinitis have been defined in the literature, none of them is directly related to prognosis, treatment options, or surgical management. The aim of this study is to create a new, easy-to-apply, practical, and treatment-related classification system for calcific tendinitis based on the localization of the deposits on MRI. Furthermore, the aim is to compile the current patient cohort according to this new classification and examine the relationship between the treatment applied and the deposit localization in the proposed classification.

Outcome Measures
Primary Outcomes (1)
Change from Baseline in American Shoulder and Elbow Surgeons (ASES) Score at 12 Months
The ASES score is a standardized shoulder assessment form. It consists of a patient self-evaluation section (visual analog scale for pain and instability) and a daily function assessment section. The score ranges from 0 to 100, where 0 indicates the worst possible outcome and 100 indicates the best possible outcome.
From preoperative assessment (baseline) to 12 months post-operation
Secondary Outcomes (1)
Change from Baseline in Subjective Shoulder Value (SSV) at 12 Months
From preoperative assessment (baseline) to 12 months post-operation
Study Arms (5)
Intratendinous Articular (Ta)
Calcific deposit sits inside the tendon, closer to the articular side
Intratendinous Bursal (Tb)
Calcific deposit sits inside the tendon, closer to the bursal side
Complete Intratendinous (Tc)
The calcific deposit is entirely within the tendon and completely encompasses the tendon substance.
Extratendinous (E)
Calcific deposit located outside the tendon.
Intraosseous (I)
Calcific deposit extending into the bone.
Interventions
Non surgical conservative treatment consist of all the treatment modalities e.g. analgesic treatment (NSAIDs, paracetamol...), ice packaging, movement restriction, resting etc.
Debridement intervention can be described as a surgical intervention, which includes debridement of the calcification deposit.
After the surgical debridement of the deposit, sometimes there is a rotator cuff defect. Side to side repair group consist of the cases when the defect is repaired side to side primarily.
Anchor fixation group consist of the cases when the rotator cuff defect cannot be repaired side to side, and the surgeon managed the defect by fixating it to the bone with an anchor.
Eligibility Criteria
The study popuation consists of individuals who were followed for calcific tendinitis and received conservative or surgical treatment by the physicians of our clinic at American Hospital and Koç University Hospital since 2004.
You may qualify if:
- Patients who underwent surgical treatment for calcific tendinitis
- Presence of single or multiple calcific deposits within the rotator cuff tendons
You may not qualify if:
- History of prior ipsilateral shoulder surgery for indications other than calcific tendinitis
- Revision surgery for calcific tendinitis
- Incomplete clinical documentation or unavailable MRI data
