Slippage after reduction of atlantoaxial rotatory fixation (AARF) is usually treated with repeated cervical traction and brace immobilization. To date, no data have been published on the management of muscle spasm during treatment. Here, we describe the case of a 7-year-old girl with AARF for 1 month who visited our hospital for treatment. During physical examination, spasm of the sternocleidomastoid muscle was noted. The patient was treated with manipulative reduction, and slippage after reduction was managed with botulinum spasticity block of the sternocleidomastoid and splenius capitis muscles, and repeated manipulation. Cervical orthosis immobilization with a rehabilitation program of isometric contract-relax exercise for the neck was conducted for 3 months. The subject had full recovery from AARF at 1-year follow-up. This report demonstrates that, in selected cases of slippage after reduction from AARF, conservative management with manipulation under anesthesia is a good method, and the muscle components may play a crucial role in AARF.

Introduction Degenerative spondylolisthesis (DS) is a degenerative condition characterized by subluxation of one vertebral body anterior to the adjacent inferior vertebral body with an intact pars. Conservative treatment approaches, such as steroid injections and physical therapy, may work well at first, but in resistant situations, surgery is frequently necessary. Posterolateral lumbar fusion (PLF) has been widely used, but transforaminal lumbar interbody fusion (TLIF) offers theoretical advantages such as improved alignment and enhanced fusion rates.

This study investigates lignin's influence on the hygroscopic behavior of poplar wood. Delignification was achieved using an acidic NaClO solution, and digital image correlation (DIC) was employed to measure strain distribution during shrinking and swelling across relative humidity (RH) ranging of 0 % to 97 %. Results showed that lignin removal increased equilibrium moisture content (EMC) by up to 3.

A novel 3D-printed clamping interface was designed to address challenges associated with the tensile testing of soft biological tissues, particularly specimen slippage and failure at the grips. To improve specimen adherence, four contact patterns, based on retrograde teeth, serrated, atraumatic wavy teeth, and flower patterns, were added to the interface surface. A smooth transition was considered to diminish the likelihood of transverse cutting of specimens.

TNK2 is a ubiquitously expressed nonreceptor-type tyrosine kinase. TNK2 participates in tumorigenesis, and TNK2 activation has been found in various cancers; therefore, TNK2 is a promising target for cancer chemotherapy. While the TNK2 inhibitor XMD16-5 is highly selective, it inhibits cytokinesis at higher concentrations by targeting Aurora B kinase, a key enzyme for cell division.
