[The shoulder prosthesis in the past 7 years: increasingly used, with good results]. / De schouderprothese in de afgelopen 7 jaar.

The shoulder prosthesis is increasingly used as a solution for various shoulder problems. On the basis of a few cases, an overview is given of the various situations in which a shoulder prosthesis can be used, with a small risk of complications, a high risk of pain reduction and a long survival. In addition, a shoulder prosthesis improves the quality of life and is cost-effective. It is important, however, to set the correct indication with an eye for various psychosocial factors. The individual end result depends on patient-related factors such as pathology, general condition, activity and expectations. But the type of prosthesis and surgical expertise and experience also play a role.

Translation and evaluation of psychometric properties of the Dutch version of the Single Assessment and Numeric Evaluation Method (SANEM) in shoulder patients.

BACKGROUND: The Single Assessment Numeric Evaluation Method (SANEM) is a holistic patient-reported outcome measure (PROM) that includes all aspects involving the shoulder. It is simple and easy to administer. It consists of only one question, namely how would you rate your shoulder today as a percentage of normal (0 to 100% with 100% being normal)? The purpose of this study was to translate the SANEM in Dutch and to assess its construct validity, reliability, and responsiveness. METHODS: The SANEM was translated into Dutch using forward and backward translation. Hypothesis testing was used to determine construct validity and responsiveness, 75% needed to be confirmed. Previous validated PROMs were used as comparator instrument for testing construct validity. Test-retest reliability (2-week interval), Standard Error of Measurement, and Smallest Detectable Change were calculated as reliability analyses. One year after baseline, we evaluated the responsiveness. RESULTS: One hundred seven patients (55% women) with a mean age of 54 years were included. Of the hypotheses formed in advance to assess construct validity, 67% was confirmed, meaning there was no adequate construct validity and the SANEM cannot replace all other PROMs. With an intraclass correlation coefficient of 0.95, excellent test-retest reliability was found. Of the hypotheses formed in advance to evaluate the responsiveness, 75% was confirmed, indicating the SANEM has good responsiveness. CONCLUSION: Although the SANEM cannot replace all other PROMs, it is a reliable instrument to assess if a patients' shoulder, regarding the whole shoulder, changes over time or stays unchanged. LEVEL OF EVIDENCE: Level II.

Spontaneous scapular spine fracture related to rotator cuff pathology: a report of two cases.

Spontaneous fractures of the scapula are rare, especially those involving the scapular spine. There are only a few case reports addressing this topic. Two cases are presented of spontaneous scapular spine fractures in patients with cuff-tear arthropathy. Treatment was conservative, resulting in a stiff shoulder in both patients. The combination of oral steroids and cuff-tear arthropathy seems to have caused a spontaneous scapular spine fracture in these patients. Considering the risk of operative intervention in the elderly patient conservative treatment seems a reasonable alternative.
