The unstable slipped capital femoral epiphysis: does the rate of osteonecrosis really depend on the timing of surgery and surgical technique?

The aim of this study was to investigate whether the timing of surgery and surgical technique affect the rate of osteonecrosis in unstable slipped capital femoral epiphysis (SCFE). This is a retrospective review of all unstable slips that were treated at our institution over 8.5 years with a minimum follow-up period of 12 months. Patients with stable slips were excluded from this analysis. Demographic data, time to surgery, and surgical technique were analyzed. Twenty-three unstable slips were included for study after excluding 40 stable slips. There were 17 males and six females, with an average age of 11.9 years; 13 patients had right SCFEs. The average time from diagnosis to surgery was 57.7 h. Nine (39.1%) surgeries were performed within 24 h of admission, whereas 14 (60.9%) surgeries were performed after 24 h. Minimum follow-up was 23 months. Two patients developed osteonecrosis: one underwent surgery within 24 h of admission and the other after 24 h. Both underwent in-situ screw fixation. In the group that did not develop osteonecrosis, 76.2% underwent in-situ screw fixation and 23.8% underwent manipulative reduction. The rate of developing osteonecrosis following screw fixation in unstable SCFE was unrelated to whether surgery was performed before or after 24 h of admission (P = 1.0), or whether in-situ screw fixation or manipulative reduction pre-fixation was performed (P = 0.605). The results of this small series challenge the practice of stabilizing unstable SCFEs e...

This study aims to examine the effectiveness of the postural treatment of the Mézières method on elite rhythmic gymnastics athletes with low back pain. DESIGN: Double-blind, randomized, controlled trial. SETTING: The sports hall of "Puente Tocinos," Murcia, Spain. PARTICIPANTS: Ninety gymnastics athletes were randomized into 2 parallel groups (intervention: n = 39; control: n = 51), of whom 98.9% were women (women = 89; man = 1). INTERVENTION: The Mézières method postural therapy was implemented. It lasted about 60 minutes in repeated sessions of 2 to 3 meetings per wee...

CONCLUSIONS: Delayed activation of the VM registered in females determines an increase in anterior shear force, which is an important risk factor for incurring an ACL injury. This testing protocol becomes adequate for the screening of high-risk athletes and for targeting interventions to specific imbalances that may increase injury risk.

Authors: Fyock M, Cortes N, Hulse A, Martin J Abstract Clinical Scenario: Patellofemoral pain (PFP) is a common knee injury in recreational adult runners, possibly caused by faulty mechanics. One possible approach to reduce this pain is to retrain the runner's gait. Current research suggests that no definitive gold standard treatment for PFP exists. Gait retraining utilizing visual feedback may reduce PFP in both the short and long term. Clinical Question: In adult runners diagnosed with PFP, does gait retraining with real-time visual feedback lead to a decrease in pain? Summary of Key Findings: A literature search...

We carry out eight configurations, mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, and octavacancies by using the density-functional-theory calculations (DFT). We calculate formation and dissociation energies to analyze the stability by finding the magic numbers. Magic numbers are the number of vacancy belonging to stable configurations. We find that di-, tetra-,...

Authors: Gabella G Abstract All the cells of rat detrusor muscle fall into one of five ultrastructural types: muscle cells, fibroblasts, axons and glia, and vascular cells (endothelial cells and pericytes). The tissue is ~79% cellular and 21% non-cellular. Muscle cells occupy 72%, nerves ~4% (1/3 axons, 2/3 glia), and fibroblast>3% of space. Muscle cells (up to 6 µm across and ~600 µm long, packed to almost 100,000 per mm2) have surface-to-volume ratio of 2.4 µm2/µm3 ~93% of cell volume is contractile apparatus, 3.1% mitochondria and 2.5% nucleus. Cell profiles are irregular but section...
