Scapular foramina - a systematic review with meta-analysis based on 3316 scapulae.

PURPOSE: In the present study, we want to systematize the previous studies on the scapular foramina (SF) and nutrient foramina (NF) with emphasis on the clinical relevance of this topic. Although seemingly not important, radiologists, clinicians and surgeons should be aware of the presence and characteristics of the SF and NF and look out for possible mistakes that may cause harm to the patients during either the diagnostic process or surgery. METHODS: A comprehensive search was conducted in multiple databases, including PubMed, Scopus, Web of Science, Embase, Cochrane Library and Google Scholar. The whole process was divided into three stages. In the first stage, the following search terms were used: ((scapular foramina) or (scapular foramen) or (scapular nutrient foramina) or (scapular nutrient foramen) or (scapula foramen) or (scapula foramina) or (scapula nutrient foramina)). RESULTS: The results of the present meta-analysis were based on a total of 3316 studied scapulae. A pooled prevalence of scapulae in which at least one SF was found was set to be 11.29%. The most common localization of the SF was found to be the infraspinous fossa, in which the SF occurred with the prevalence of 52.31%. Subsequently, a pooled prevalence of scapulae in which at least one NF occurs was established at 74.23%. CONCLUSION: The presented data contribute to a comprehensive understanding of the prevalence, distribution, and characteristics of suprascapular and nutrient foramina in scapulae, considering different topographical areas, genders, and sides.

Validation of the Polish version of the Hand Function Scoring system.

BACKGROUND: The Hand Function Scoring (HFS) system was created to assess the results of rehabilitation treatment after hand injuries. A perceived hand function improvement in patients who underwent carpal tunnel syndrome surgery prompted us to use the Watts HFS questionnaire in our study. OBJECTIVES: The study aimed to: 1) translate and validate the new questionnaire into Polish; 2) analyze the usefulness of the scale in the preand post-operative assessment of patients with carpal tunnel syndrome; and 3) compare the results with other questionnaires recognized as the gold standard in carpal tunnel treatment evaluation. MATERIAL AND METHODS: Patients with electromyographically confirmed carpal tunnel syndrome (n = 317) were enrolled in the study. Participants completed the HFS, Boston Carpal Tunnel Questionnaire (BCTQ), Michigan Hand Outcomes Questionnaire (MHQ), and the Quality-of-Life Scale (QoLS) on their first visit to our clinic. Two weeks later, 84 patients completed the same questionnaires again, and 6-12 months after the operation, we received 90 additional responses. RESULTS: The analysis showed that the HFS questionnaire met the validation criteria and had a strong correlation with the BCTQ questionnaire for the Symptoms Severity Scale (SSS) (Rho = 0.70, p < 0.001) and the Functional Status Scale (FSS) (Rho = 0.89, p < 0.001). CONCLUSIONS: The HFS questionnaire was successfully employed in the subjective assessment of carpal tunnel symptom syndrome severity and the analysis of treatment results, and would complement the clinical assessment of patients during treatment. The questionnaire could also be used in future scientific research.
