Unstable pelvic fractures associated with femoral shaft fractures: a retrospective analysis.

Background: Both pelvic fractures and femoral shaft fractures are caused by high-energy injuries. When unstable pelvic fractures and femoral shaft fractures occur concomitantly, the optimal treatment method is controversial. The aim of this study was to establish a reasonable principle for treating such complicated injuries.

Modified technique of percutaneous posterior columnar screw insertion and neutralization plate for complex acetabular fractures.

Background: To overcome the complexity of acetabular fractures, several techniques, such as extensive surgical exposure, transtrochanteric osteotomy, and columnar screw fixation, were reported. However, all these techniques have their disadvantages and limitations. We report the surgical results of a modified technique with posterior columnar screw insertion and neutralization plate in a single Kocher-Langenbeck approach for complex acetabular fractures.

The use of fluorescence-labeled mesenchymal stem cells in poly(lactide-co-glycolide)/hydroxyapatite/collagen hybrid graft as a bone substitute for posterolateral spinal fusion.

Background: Posterolateral spinal fusion is used to treat patients with degenerative spinal disorders. In this study, we investigated the effectiveness of a mesenchymal stem cell (MSC)/hydroxyapatite/type I collagen hybrid graft for posterolateral spinal fusion in a rabbit model.

Methods: In vitro study, the hybrid graft was cultured in complete or osteogenic medium for 7 days and 14 days and examined by scanning electron microscopy.

Short- to medium-term outcomes of radial head replacement arthroplasty in posttraumatic unstable elbows: 20 to 70 months follow-up.

Background: The radial head is considered the main stabilizer of the elbow when the medial collateral ligament and lateral ulnar collateral ligament have been compromised. Radial head replacement (RHR) is indicated for patients with irreparable or non-united radial head fractures associated with elbow stiffness or instability. The present study aimed to analyze the clinical results after treatment with titanium radial head prostheses, repair of torn soft tissue constraints, and early mobilization of the elbow.

Reconstruction intramedullary nailing for ipsilateral femoral neck and shaft fractures: main factors determining prognosis.

Background: Ipsilateral femoral neck and shaft fractures are rare, and currently available treatment methods each have their own benefits and limitations. Although reconstruction intramedullary nails have been considered to be effective alternative, clinical outcomes vary significantly in reports.

Methods: Thirty-seven consecutive adult patients with 37 combined fractures were treated with reconstruction intramedullary nails.

Use of fluorescence labeled mesenchymal stem cells in pluronic F127 and porous hydroxyapatite as a bone substitute for posterolateral spinal fusion.

Posterolateral spinal fusion is used to treat patients with degenerative spinal disorders. We investigated the effectiveness of a mesenchymal stem cell (MSC)/Pluronic F127/Interpore hybrid graft for spinal fusion in rabbits. Spinal fusion was examined using radiography, manual palpation, computed tomography (CT), torsional loading tests, and histological analysis.

Osteoblastic differentiation of rabbit mesenchymal stem cells loaded in A carrier system of Pluronic F127 and Interpore.

Background: Ideally, bone tissue engineering products should have the ability of osteoconduction and osteoinduction. According to the tissue engineering principle, mesenchymal stem cells (MSCs) combined with an appropriate scaffold can be used as a bone substitute for bone defects. Here we used Interpore as a scaffold loaded with MSCs mixed in hydrogel (Pluronic F127).

Arthroscopic evaluation of soft tissue injuries in tibial plateau fractures: retrospective analysis of 98 cases.

Purpose: This investigation arthroscopically assesses the frequency of soft tissue injury in tibial plateau fracture according to the severity of fracture patterns. We hypothesized that use of arthroscopy to evaluate soft tissue injury in tibial plateau fractures would reveal a greater number of associated injuries than have previously been reported.

Methods: From March 1996 to December 2003, 98 patients with closed tibial plateau fractures were treated with arthroscopically assisted reduction and osteosynthesis, with precise diagnosis and management of associated soft tissue injuries.

Closed femoral nailing in lateral decubitus position without a fracture table: a preliminary report of fifteen patients.

Background: The use of a fracture table is standard for closed intramedullary nailing of femoral fractures. Instead of a fracture table, some clinicians have successfully performed this operation in the supine position via manual traction. Here, we present our experience performing this operation in the lateral decubitus position without a fracture table.
