Why does outer joint motion predominate in bipolar hip prosthesis? Experimental and clinical studies.

Acta Orthop Scand 2004 Dec;75(6):701-7

Department of Orthopedics, Chonnam National University Hospital, Gwangju, Korea.

Background: Theoretically, the motion of a bipolar hip prosthesis is most likely to occur at the inner joint if the frictional coefficients are equal at both surfaces. However, many studies have suggested that most motion occurs at the outer joint.

Material And Methods: We performed an analysis of motion in a cadaveric bone model and in 50 patients during fluoroscopic examination, to determine how the motion is distributed between the two joints and what factors contribute to this distribution. Read More

Parathyroid hormone--a drug for orthopedic surgery?

Acta Orthop Scand 2004 Dec;75(6):654-62

Department of Orthopedics, University Hospital Eppendorf, Hamburg, Germany.

Whereas continuous exposure to PTH results in bone resorption, administration at intermittent doses results in bone formation by increasing osteoblast number and activity. The anabolic action of PTH has also been demonstrated in clinical trials, in which PTH increased the bone mass and reduced fracture rate in patients with osteoporosis. In animal models of fracture healing and fixation of orthopedic implants, PTH increases the bone density in a dose-dependent manner, leading to faster repair and better fixation. Read More

Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence.

Authors:
Jacob Engellau

Acta Orthop Scand Suppl 2004 Dec;75(314):2 p preceding table of contents-52, backcover

Department of Oncology, Lund University Hospital, Lund University, Sweden.

In adult soft tissue sarcoma (STS) of the extremities and trunk wall, improved prognostic factors are needed to identify patients at high-risk for metastasis. Various factors are included in the many prognostic systems currently in use and the prognostic value of immunohistochemical (IHC) expression of biological markers is unclear. The tissue-preserving, high throughput tissue microarray (TMA) technique for analysis of immunohistochemical expression of biological markers was validated for Ki-67, and was found to yield results comparable to conventional staining methods.

Lumbar spinal fusion. Outcome in relation to surgical methods, choice of implant and postoperative rehabilitation.

Acta Orthop Scand Suppl 2004 Oct;75(313):2-43

Faculty of Health Sciences, University of Aarhus, Spine Section, Orthopaedic Department, Orthopaedic Research Laboratory, Institute of Experimental Clinical Reaserch, Aarhus University Hospital, Denmark.

Unlabelled: Chronic low back pain (CLBP) has become one of the most common causes of disability in adults under 45 years of age and is consequently one of the most common reasons for early retirement in industrialised societies. Accordingly, CLBP represents an expensive drain on society's resources and is a very challenging area for which a consensus for rational therapy is yet to be established. The spinal fusion procedure was introduced as a treatment option for CLBP more than 70 years ago. Read More

Selective botulinum toxin injection in the treatment of recurrent deformity following surgical correction of club foot: a preliminary report of 3 children.

Acta Orthop Scand 2004 Oct;75(5):630-3

West Middlesex University Hospital, Isleworth, Middlesex TW7 6AF, UK.

Management of a child with club foot deformity that recurs after an apparently successful posteromedial soft tissue release remains a challenge. Revision surgery is often attempted, but this carries a high risk of significant scarring or neurovascular complications. We have treated 3 children (3 feet) with relapsed club foot and fixed deformities, using Botulinum toxin A (BTX-A) injection into muscle groups clinically thought to be responsible for recurrent deformity, followed by moulded plaster casts.

Bone grafting the scaphoid nonunion: a systematic review of 147 publications including 5,246 cases of scaphoid nonunion.

Acta Orthop Scand 2004 Oct;75(5):618-29

Hand Section, Aarhus Amtssygehus, University Hospital of Aarhus, Denmark.

In order to elucidate the history of scaphoid nonunion and to evaluate whether or not the problem has been solved, we have reviewed the literature from 1928 to 2003 for union rates, postoperative immobilization periods and complications of the different scaphoid bone grafting procedures. The outcomes of 5 246 scaphoid nonunions were evaluated in three treatment groups. In the first group involving nonvascularized bone grafting without internal fixation, we found a union rate of 80% (95% CI: 78-82) after an average immobilization period of 15 weeks. Read More

Posttraumatic instability of the elbow joint can be osseous or ligamentous. Ligamentous instability can be in valgus or in posterolateral rotatory direction. Rupture of both the lateral and medial collateral ligament of the elbow can be seen as an isolated injury, or it can be part of a more complex injury such as a dislocation. Read More

Combined radiology and cytology in the diagnosis of bone lesions: a retrospective study of 370 cases.

Acta Orthop Scand 2004 Aug;75(4):492-9

Department of Radiology, Karolinska Hospital, SE-171 76 Stockholm, Sweden.

Background: Some of the risks with open biopsy can be avoided by fine-needle aspiration biopsy. The diagnostic contribution of radiologic findings has not been systematically studied.

Patients And Methods: We retrospectively analyzed the validity of combined radiology and fine-needle aspiration cytology for the diagnosis of bone lesions in a consecutive series of 370 patients. Read More

Role of MMP-9 and its tissue inhibitor TIMP-1 in human osteosarcoma: findings in 42 patients followed for 1-16 years.

Acta Orthop Scand 2004 Aug;75(4):487-91

Laboratory of Oncologic Research, Rizzoli Orthopaedic Institute, Bologna, Italy.

Background: The activity of matrix metalloproteinases (MMPs) in degrading extracellular matrix is controlled by activation of proenzymes and inhibition of MMP tissue inhibitors (TIMPs).

Patients And Methods: To assess the proteolytic cascade imbalance in malignancy progression, tissue expression and serum levels of MMP-2, MMP-9 and of their inhibitors TIMP-2 and TIMP-1 respectively were evaluated in 42 selected patients with high-grade osteosarcoma (OS). MMP-2, MMP-9, TIMP-2 and TIMP-1 were studied in biopsies by immunohistochemistry and in serum by ELISA test. Read More

Secondary intramedullary nailing after distraction osteogenesis: 30 patients followed for 2-12 years.

Acta Orthop Scand 2004 Aug;75(4):481-6

Department of Orthopaedic Surgery, Patras University Medical Center, Rio-Patras, Greece.

Background: There is no consensus about replacement of an external fixator by reamed intramedullary nailing in fracture cases.

Patients And Methods: We evaluated the outcome in 30 patients (33 segments) of secondary intramedullary nailing during the consolidation phase after callus distraction using an external device. The main reasons for nailing were docking site nonunion (17 patients), angular deformity or fracture of the lengthened area (8 patients) or intolerance of the external device (5 patients), in 11 patients combined with a delayed distracted callus maturation.

Early intramedullary nailing of lower extremity fracture and respiratory function in polytraumatized patients with a chest injury: a retrospective study of 61 patients.

Acta Orthop Scand 2004 Aug;75(4):477-80

Department of Orthopedics and Traumatology, Helsinki University Central Hospital, Finland.

Background: The optimal treatment of diaphyseal fractures of the lower extremities in patients who also have serious chest injuries is not known.

Patients And Methods: We retrospectively evaluated the effect of an early intramedullary nailing (IMN) of femur or tibia fractures on respiratory function in 61 consecutive polytraumatized patients with unilateral or bilateral pulmonary contusion (thoracic AIS=3) admitted to our trauma intensive care unit between January 2000 and June 2001. 27 patients had a diaphyseal fracture of at least one long bone of the lower extremity, which was treated with IMN within 24 hours of admission.
