Randomized Controlled Trial
Multiplanar reconstruction computed tomography for diagnosis of scaphoid waist fracture union: a prospective cohort analysis of accuracy and precision.
To examine reliability and validity concerning union of scaphoid fractures determined by multiplanar reconstruction computed tomography randomized at 6, 12, and 24 weeks after injury. ⋯ Our results suggest that multiplanar reconstruction computed tomography is a reliable and accurate method for diagnosing union or nonunion of scaphoid fractures. However, inter-observer agreement was lower with respect to partial union.

Glomus coccygeum is a network of glomus bodies located around pericoccygeal soft tissue. The question of whether it accounts for coccydynia has been debated. We report on a patient whose preoperative symptoms suggested the impression of glomus tumor of the coccyx; pain was relieved after removal of the lesion without coccygectomy. ⋯ The pathology report confirmed a glomus tumor, which was an identical finding to the conventional one of the subungual region. Ten months after surgery, she had no pain on the coccygeal region and no difficulty with sitting on a chair and in performing activities of daily living. Findings reported here suggest that although most glomus bodies are normal anatomical variants, development of a glomus tumor could occur in the coccygeal region and could be a cause of coccydynia.

Comparative Study Controlled Clinical Trial
Lumbar nerve root injections: a prospective cohort outcomes study comparing age- and gender-matched patients who returned an outcomes-based postal questionnaire with patients who did not return the postal questionnaire.
The purpose of this study is to investigate if relying on postal questionnaires returned by patients provides an accurate representation of reported outcomes from patients receiving imaging-guided lumbar nerve root injections (NRIs). ⋯ Patients returning postal questionnaires reported less favorable outcomes compared to those who did not return their questionnaires.

To determine if a statistical association exists between abnormalities in one ankle tendon group (i.e., peroneal, medial flexor, or Achilles) and those in another. ⋯ There is an association between quantitative and qualitative abnormalities of one group of tendons when compared with the others with respect to the ACH, medial flexor, and peroneal tendons of the ankle, which is perhaps explained by a retinacular and fascial complex that anatomically connects the three groups.
