Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy occurring in upper limbs. The etiology, however, has not been fully understood yet. Median nerve could be compressed by either increase of carpal tunnel pressure (CTP) or direct impingement when it is forced toward to carpal ligament especially in wrist flexion leading to CTS development. Thus, the increase of carpal tunnel pressure is considered an important role in CTS development. It has been identified that forces applied to the palm would affect the CTP...

Vertebral pathological fracture and metastatic epidural spinal cord compression (MESCC) due to metastatic cancer inevitably cause pain, neurological deficit, impaired function, and decreased quality of life and are indications for surgery. In such cases, earlier surgical intervention has the potential to prevent permanent neurological deficit and disability and to maintain function and quality of life. Therefore, the aim of this study was to identify and evaluate risk factors for pathological fracture and MESCC in patients with spinal metastases...

Foraminal stenosis causing nerve root compression and radiculopathy is a relatively common pathology in the lumbar spine. The treatment of choice, when surgery is indicated, is foraminal decompression at the affected level, usually through a conventional midline open foraminotomy. Minimally invasive lateral foraminotomy with partial lateral facetectomy is a potentially effective surgical alternative when such a surgery is warranted. The evaluation of the efficacy and benefits of this approach for treatment of radiculopathy; an assessment of facet integrity; and, a detailed description of the procedure are also provided...

Victor E Staartjes, Marc L Schröder
BACKGROUND: The addition of fusion to decompression for stenosis with Grade I degenerative spondylolisthesis is a controversial topic, and the question remains if fusion provides any real benefit to the patient that warrants the increased healthcare utilization and perioperative morbidity. In addition, there is no consensus on indications for the use of fusion over decompression alone. METHODS: Patients received fusion or decompression according to a decision-making protocol based on their pattern of complaints, the location of the compression, as well as facet angles and effusion as proven predictors of postoperative instability...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...
