Triggering of the finger at the A1 pulley is one of the most frequent pathologies encountered in hand surgery and a common cause of hand pain. Open release of the A1 pulley is currently still regarded as the golden-standard procedure. Nevertheless, there is an increasing interest in minimally invasive percutaneous techniques for the treatment of this condition. Current techniques range from percutaneous needle techniques without imaging, to the use of hook knives, with ultrasound guidance. Because of concerns about possible complications or incomplete releases, hand surgeons remain wary. The objective of this study was to introduce a new ultrasound-guided percutaneous surgical technique for trigger finger release, using a second-generation minimally invasive surgical knife. In this series of 78 releases, complete resolution of the symptoms was found in 98.7% of the cases. One recurrence of triggering was observed. There were no tendon injuries, infections, or neurovascular lesions recorded. This paper contains technical pearls and possible pitfalls to ensure the surgeon of a complete release and to avoid complications. A video of the technique was also included as Supplemental Digital Content (http://links.lww.com/BTH/A143). We can conclude that the procedure can be considered as safe and highly effective for the treatment of triggering at the A1 pulley.
Here, we report a case of idiopathic epidural lipomatosis presented with a clinical picture of lumbar canal stenosis with neurogenic claudication which resolved completely only by weight loss. A 53-year-old obese male with a body mass index of 36 without significant past medical history presented to the outpatient clinic with neurogenic claudication and bilateral sciatic radiculopathy. Initially, magnetic resonance imaging (MRI) showed epidural lipomatosis at the level of L5 vertebral body and L5–S1 intervertebral disc. A conservative treatment was decided with dietary regime program. After 6 months of follow-up, his bilateral sciatic radiculopathy disappeared, and updated MRI showed complete disappearance of epidural lipomatosis. Based on the Grand Round case and relevant literature, we present a case of an unusual epidural lipomatosis with mixed clinical picture of degenerative lumbar disease. This case report set out the importance of Borré classification for differentiating the mixed clinical complaint of degenerative discopathy and epidural lipomatosis.
Study Design A prospective study of healthy volunteers Objectives The influence of the sagittal alignment of the spine and its influence on the extension reserve have been reported in the literature. However, specific analysis of the intrinsic coxofemoral and extrinsic pelvic component in subjects without any spinal or hip pathologies remains poorly reported. The aim of this study was to categorize the hip extension capacity, or extension reserve (ER), in relation to spinal sagittal alignment whilst standing, in a young healthy population. We hypothesized that the global extension reserve (GER) of the hip joint was influenced by the sagittal spinopelvic alignment. Methods We evaluated the ER of 120 healthy Caucasian volunteers (56 females (46.7%), 74 males (53.3%); mean age 25.6 years), using low dose radiographs from an EOS® X-ray imaging system in 2 functional positions; neutral standing position and in a forward lunge position. The GER is defined as the sum of the intrinsic (hip) extension reserve (IER) and the extrinsic (pelvic) extension reserve (EER). Cases were grouped into 4 sagittal alignment subtypes according to the Roussouly classification, and analyzed. Results Global extension reserve values were not significantly different between the 4 Roussouly subtypes ( P = .094), nor between patients with a sacral slope (SS) <35° (types 1/2) and ≥ 35° (type 3/4) ( P = .837). Statistically significant differences were seen between IER in each subtype ( P = .015), and EER ( P = .006). No difference in ER was seen between subtypes regarding pelvic incidence (PI). Conclusion An inverse relationship was found between IER and EER among Roussouly subtypes. The range of motion of the pelvis and the hip joint was higher in patients with a greater sacral slope.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
