Acromion clavicular joint reconstruction with LArS ligament in acute dislocation
Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependent upon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicular separation with several static and dynamic operative procedures with or without primary ligament replacement. Methods: 47 patients with acute Rockwood type III, IV, and V injuries were treated surgically with LARS reconstruction. The success of technique was evaluated by radiographic outcomes for each patient at every follow-up visit (one,three, 12 months), while to assess pain reduction and clinical evaluation Visual Analogue scale score (VAS) and Constant-Murl…
Atractyligenin chemistry. Part 4: Synthesis of the 15β-ol epimer of atractyligenin
The oxidation with PCC of atractyligenin 3, the aglicone of the toxic glycoside 1 isolated from Atractylis gummifera L., led to the 15-oxo-derivative 6, together with a small amount of 2,15-dioxoderivative 5, with a selective oxidation of the allylic 15-OH group of the molecule. Further reduction with NaBH4 and KOH hydrolysis gave stereoselectively the 15β-ol epimer of atractiligenin 9.
Fractional order hereditariness of knee human ligament and tendon
Anterior Cruciate Ligament (ACL) is one of the four major ligaments in the knee, playing a critical role in stabilizing the joint. ACL is highly susceptible to injury, overall during sport activities, often precipitating catastrophic long-term joint outcomes. The ideal replacement graft for a torn ACL would restore native anatomy and function to the knee. Most commonly used autograft and allograft, including patellar tendon (P) and hamstring tendon (H) graft, or bioengineered synthetic grafts, may substantially alter the biomechanics of the knee, permitting a return to only moderate physical activities [1]. Main issues are the sub-optimal graft properties [2] and a still incomplete biomecha…
