Review Case ReportsIntraoperative conjoined lumbosacral nerve roots associated with spondylolisthesis.
Lumbosacral nerve roots anomalies may produce low back pain. These anomalies are reported to be a cause for failed back surgery. ⋯ In this report, we describe our experience with a case of L5-S1 spondylolisthesis and associated congenital lumbosacral nerve root anomalies discovered during the surgical intervention, and the difficulties raised by such a discovery. Careful examination of coronal and axial views obtained through high-quality Magnetic Resonance Imaging may lead to a proper diagnosis of this condition leading to an adequate surgical planning, minimizing the intraoperatory complications.

Review Case ReportsSurgical treatment of high-grade dysplastic spondylolisthesis using intraoperative electrophysiological monitoring: report of two cases and review of the literature.
Treatment of high-grade dysplastic spondylolisthesis in adolescents remains challenging. Surgical treatment of spondylolisthesis has been recommended in adolescents with pain refractory to conservative treatment, slippage progression, or severe slippage on presentation. Controversy exists as to the optimal surgical approach for high-grade spondylolisthesis. ⋯ A postoperative radiogram showed reduction of the slippage, and computed tomogram showed bone union between L5 and S1 vertebral body. This report describes 2 cases of surgical treatment using intraoperative electrophysiological monitoring with transcranial electric motor evoked potentials and continuous spontaneous electromyography for patients with high-grade dysplastic spondylolisthesis in adolescence. We successfully perform the surgery without any neurological deficit using intraoperative electrophysiological monitoring.

Dislocated intra-articular femoral head fracture associated with fracture-dislocation of the hip and acetabulum: report of 12 cases and technical notes on surgical intervention.
This report describes case series of the femoral head fractures associated with fracture-dislocation of the hip joint to evaluate the mid- and long-term outcomes and to highlight the surgical technique of fixation of the femoral head from the posterior trochanteric flip osteotomy approach. Twelve patients (6 men and 6 women) with dislocated femoral head fractures (mean age at the time of injury, 56 years; range, 23-80) were followed up for mean period of 9.7 years (range, 5-20). All dislocations were reduced within less than 6 h after the injury. ⋯ The latter patient sustained Pipkin type IV and developed osteoarthritis 1 year after surgery and consequently required total hip arthroplasty. We conclude that small fragment of the femoral head less than 1 cm can be removed, while larger fragments should be fixed by bioabsorbable screws or pins in all types of femoral head fractures. In Pipkin type IV fractures, surgeons should always take anatomical reduction in the acetabulum into consideration during surgery.

Management of Vancouver type B2 and B3 femoral periprosthetic fractures using an uncemented extensively porous-coated long femoral stem prosthesis.
The purpose of this study was to evaluate the clinical results of femoral revision using an uncemented extensively porous-coated long femoral stems with or without onlay strut allografts in the treatment of Vancouver type B2 and B3 periprosthetic femoral fractures. ⋯ An uncemented extensively porous-coated long femoral stem together with or without onlay strut allografts provides a good fracture stability that promotes fracture healing and offers a successful solution for the management of Vancouver type B2 and B3 femoral periprosthetic fractures.

Correction of post-traumatic thoracolumbar kyphosis using pedicle subtraction osteotomy.
The aim of this study was to retrospectively analyze and evaluate the effect of treatment employing pedicle subtraction osteotomy for chronic, posttraumatic thoracolumbar kyphosis. This study included 19 patients, 11 males and 8 females, with chronic, posttraumatic thoracolumbar kyphosis. Pre-operative kyphosis ranged from 31° to 63°. ⋯ No significant loss of correction was observed (loss of 1.7°), and solid fusion was achieved in all 19 patients. A single-stage posterior pedicle subtraction osteotomy is a safe and effective procedure for correction of posttraumatic thoracolumbar kyphosis. Using this technique, it is possible to safely obtain no greater than 55° of correction at a single level.
