Isolated Fracture Dislocation of Medial Humeral Condyle Without Elbow Dislocation: Mechanism of an Unreported Injury.

Dislocations of elbow are often associated with fractures in proximal radius and/or ulna. In adults, fracture dislocations involving humeral condyle are exceptional and have been reported only in association with lateral humeral Condyle. Medial condyle Fracture dislocations have not been reported in adults. We present a curious case of isolated fracture dislocation of medial humeral condyle in an adult in a setting of supracondylar-intercondylar fracture of distal humerus in which elbow joint remains in position, while medial condylar fracture fragment gets dislodged from olecranon notch. A possible mechanism of injury is explained.

Radiological protocol in spinal trauma: literature review and Spinal Cord Society position statement.

PURPOSE: The Spinal Cord Society constituted a panel tasked with reviewing the literature on the radiological evaluation of spinal trauma with or without spinal cord injury and recommend a protocol. This position statement provides recommendations for the use of each modality, i.e., radiographs (X-rays), computed tomography (CT), magnetic resonance imaging (MRI), as well as vascular imaging, and makes suggestions on identifying or clearing spinal injury in trauma patients. METHODS: PubMed was searched for the corresponding keywords from January 1, 1980, to August 1, 2017. A MEDLINE search was subsequently undertaken after applying MeSH filters. Appropriate cross-references were retrieved. Out of the 545 articles retrieved, 105 relevant papers that address the present topic were studied and the extracted content was circulated for further discussions. A draft position statement was compiled and circulated among the panel members via e-mail. The draft was modified by incorporating relevant suggestions to reach a consensus. RESULTS AND CONCLUSION: For imaging cervical and thoracolumbar spine trauma patients, CT without contrast is generally considered to be the initial line of imaging and radiographs are required if CT is unavailable or unaffordable. CT screening in polytrauma cases is best done with a multidetector CT by utilizing the reformatted images obtained when scanning the chest, abdomen, and pelvis (CT-CAP). MRI is indicated in cases with neurological involvement and advanced cervical degenerative changes and to determine the extent of soft tissue injury, i.e., disco-ligamentous injuries as well as epidural space compromise. MRI is also usually performed when X-rays and CT are unable to correlate with patient symptomatology. These slides can be retrieved under Electronic Supplementary Material.

Clinical Correlation between Muscle Damage and Oswestry Disability Index Score after Open Lumbar Surgery: Does Open Surgery Reduces Functional Ability?

STUDY DESIGN: Single-surgeon, single-center prospective study with prospective data collection. PURPOSE: To clinically evaluate muscle damage after open lumbar surgery and its relationship to functional activity and to validatethe improvement in function as indicated by improved Oswestry Disability Index (ODI) score despite muscle damage. OVERVIEW OF LITERATURE: Few studies have analyzed the functional loss and recovery pattern of muscles after open lumbar surgery. METHODS: The study included 30 patients who underwent open lumbar spine fusion surgery at our institution between August 2013 and May 2015. Preoperatively and at 6 months postoperatively, the patients were subjected to functional, biochemical, electrophysiological, and radiological assessments as outpatients, and the results were compared. RESULTS: Mean preoperative and 6-month postoperative values were as follows: creatine phosphokinase levels, 133.07±17.57 and 139±17.7 U/L (p <0.001); Visual Analog Scale scores for backache, 6.73±0.88 and 3.27±0.96 (p <0.001); and ODI scores, 41.6±5.51 and 22.4±4.48 (p <0.001), respectively. Preoperatively, electrophysiological studies showed that 20% of the patients had a polyphasic configuration whereas at 6 months postoperatively, all patients had polyphasic configuration (p <0.001). The mean cross-sectional area of the multifidus observed using magnetic resonance imaging (MRI) decreased from 742.67±76.62 mm2 preoperatively to 598.27±66.38 mm2 6 months postoperatively (p <0.001), with all the patients exhibiting grade 2 atrophy. CONCLUSIONS: Open lumbar fusion surgery resulted in significant damage to the lumbar paraspinal muscles, as indicated by a reduction in the cross-sectional area of the multifidus by MRI and denervation of the multifidus demonstrated using electromyography. Nevertheless, the patients reported reduced back pain and improved quality of life, which may have been due to increased stability of the previously unstable lumbar spinal segment after the surgery.
