Calcific Tendinitis in the Elbow Presented as Acute Tennis Elbow

Calcific Tendinopathy Atypically Located Outside the Rotator Cuff: A Systematic Review

BACKGROUND AND PURPOSE

Calcific tendinopathy is a common cause of painful shoulder easily identified with ultrasound or conventional radiography. Although the rotator cuff is by far the most common location of the disease and diagnostic or treatment strategies are well known in clinical practice, a lack of awareness characterizes the assessment of the other sites affected by this condition; consequently, the risk of underestimating the prevalence of atypical non-rotator cuff calcific tendinopathy is high. This may lead to expensive or invasive diagnostic exams and/or inappropriate treatment, whereas the condition is usually self-limited. The present study aims at analysing the frequency of calcific tendinitis in uncommon sites, in order to fill a gap in knowledge and awareness regarding non-rotator cuff calcific tendinopathy, thus avoiding improper clinical choices and helping to identify this condition.

METHODS

This systematic review was conducted following the PRISMA guidelines. We performed a search on Pubmed and Scopus databases concerning atypically sited extra-rotator cuff calcific tendinopathy published since 1950.

RESULTS

The research found a total of 267 articles and 793 non-rotator cuff cases of calcific tendinopathy registered. The spine (213 – 26.86%), foot and ankle (191 – 23.95%), and hip (175 – 22.06%) appeared to be the most common sites of calcific tendinopathy after the rotator cuff, whereas the longus colli C1-C2 (204 – 25.72%), Achilles (173 – 21.81%), and rectus femori (61 – 7.69%) were the most commonly affected tendons.

CONCLUSION

A better awareness of this condition in several different sites of the body than the rotator cuff could avoid unnecessary choices both in assessment and treatment.

Association of Clinical and Radiological Features in Various Repetitive Stress Injuries

Objectives 

To assess the clinical and radiological features of repetitive stress injuries (RSIs), specifically de Quervain’s (DQ) disease, tennis elbow (TE), and plantar fasciitis (PF).

Methods

This was an observational study conducted for eight months (March 2019 to September 2019) at the Orthopedic Department in collaboration with the Radiology Department. Clinically diagnosed RSI patients from both genders, aged between 30 and 50 years, were included in the study. Clinical features that were considered include pain, swelling, and site of injury. Radiological findings from ultrasound, X-ray, and magnetic resonance imaging (MRI) were identified in all participants of the study. Data were analyzed using SPSS Version 21 (IBM Corp., Armonk, NY, USA). Data were represented as frequency and percentages.

Results

There were a total of 82 patients (40 males,42 females) with repetitive stress injury (RSI), with a mean age of 42.63±8.53 years. Of the 82 patients, 34 (41.4%) had DQ disease, 28 (34.1%) had TE, and 20 (24.4%) had PF. Pain and swelling were observed in all patients. In TE, the most affected site was the right lateral epicondyle process. The common radiological findings were hypoechoic fascia, increased fluid within the first extensor tendon compartment, cortical erosion, sclerosis in soft tissues, and calcification in soft tissues. Cozen’s test was positive in most patients. In DQ, the most affected sites were left and right radial styloid processes. The common radiological findings were hypoechoic fascia, increased fluid within the first extensor, cortical erosion, and periosteal reaction. Finkelstein’s test was also positive in most patients. In PT, the most affected site was the left heal plantar surface. The common radiological findings were hypoechoic fascia, increased thickness of fascia (>4.5 mm), increased fluid within the first extensor tendon compartment, cortical erosion, sclerosis in soft tissues, calcaneal spur, periosteal reaction, and calcification in soft tissues. Cozen’s and Finkelstein’s tests were also positive in most patients.

Conclusions

History, physical examination, laboratory findings, and imaging modalities all are important tools for the differential diagnosis of RSI. Our study results showed that if some clinical findings fail to diagnose any RSI, then ultrasound, X-ray, and magnetic resonance imaging (MRI) are the best and useful options before treatment.
