Successful retrieval of a broken pituitary rongeur tip from the lumbar intervertebral disc space using a magnetic probe: illustrative case.

Background: Unexpected events such as instrument breakage during a routine lumbar microdiscectomy can pose a risk for nerve root injury, durotomy, infection, and anterior displacement into the retroperitoneal space. Removal of broken instruments requires planning, patience, and sometimes subsequent surgical procedures. Here, the authors explore the effectiveness of a magnetic probe for the retrieval of broken metallic (magnetic) pieces.

[Results to 4-year follow-up of the treatment of the cervical stenosis by corpectomy, titanium mesh cage and anterior plate fixation].

Background: Cervical spondylotic myelopathy is caused by cervical stenosis. Several techniques have been described for the treatment of multilevel disease, such as the anterior corpectomy with titanium mesh cage and anterior cervical plate placement, which has the advantage of performing a wider decompression and using the same bone as graft. However, it has caused controversy since the collapse of the mesh cage continues being a major limitation of this procedure.

Arthroscopic retrieval of a broken guidewire fragment from the hip joint after cannulated screw fixation of slipped capital femoral epiphysis.

The use of cannulated screws for internal fixation of slipped capital femoral epiphysis (SCFE) is recognized as the standard method of treatment and has fewer complications compared with previous methods such as pins or tri-flanged nails. Some complications related to guidewires have been reported in the treatment SCFE. The most dangerous complication is inadvertent advance of the guidewire into the pelvic cavity.

Adjacent segment disease in a patient with klippel-feil syndrome and radiculopathy: surgical treatment with two-level disc replacement.

Klippel-Feil syndrome (KFS) is a complex congenital condition characterized by improper segmentation of cervical motion segments that could contribute to undesirable adjacent segment degeneration. KFS patients have a strong tendency to present with disease in the adjacent segments. When this condition is present, anterior decompression followed by total disc replacement can be performed safely and can lead to good clinical results.

[Bone grafts in orthopedic surgery].

In orthopedic surgery the demand for the use of bone grafts increases daily because of the increasing quantity and complexity of surgical procedures. At present, the gold standard is the autologous bone graft but the failure rate, morbidity of the donor site and limited availability have stimulated a proliferation for finding materials that work as bone graft substitutes. In order to have good success, we must know the different properties of these choices and the environment where the graft is going to be used.
