Clinical assessment of tibial torsion differences. Do we always need a computed tomography?

Background: Tibial torsional malalignment presents a well-known complication of intramedullary nailing for tibial shaft fractures.

Purpose: Objective of this study was to investigate the ability to clinically assess tibial torsion differences. Computed Tomography (CT) was used here as the gold standard.

Midterm results after unicompartmental knee replacement with all-polyethylene tibial component: a single surgeon experience.

Purpose: The aim of this study was to determine the survival rate, the causes of failure, and the functional outcomes of an all-polyethylene tibial unicompartmental knee prosthesis.

Methods: One hundred (100) nonselected, consecutive patients indicated for unicompartmental knee replacement for isolated medial knee compartment osteoarthritis by a single surgeon at a single institution from 2000 to 2004 were included in this study. Data was collected retrospectively at final follow-up from the hospital electronic database, including progress notes, demographic information, Hospital for Special Surgery (HSS) Knee Score, details on the surgical procedure, reoperations/revisions, and mortality.

A cadaver study comparing intraoperative methods to analyze lower limb alignment.

Background: Conventional intraoperative determination of lower limb alignment is essential for orthopedic surgical treatment. Current methods include the cable, alignment rod, and axis board methods.

Question/purposes: Are there differences in accuracy and reliability? What are the individual differences in applicability and radiation exposure?

Methods: Twenty legs from 12 fresh-frozen cadavers were randomly selected.

Radiological outcome and intraoperative evaluation of a computer-navigation system for femoral nailing: a retrospective cohort study.

Aim: Intraoperative determinations of femoral antetorsion and leg length during fixation of femoral shaft fractures present a challenge. In femoral shaft fracture fixations, a computer-navigation system has shown promise in determining antetorsion and leg length discrepancies. This retrospective cohort study aimed to determine whether the use of computer navigation during femoral nailing procedures reduced postoperative femoral malrotation and leg length discrepancy, as well as the number of revision cases.

Intra-operative assessment of femoral antetorsion using ISO-C 3D: a cadaver study.

Aim: The aim of this study was to check the feasibility and accuracy of measuring antetorsion during surgery using a mobile image intensifier (IF) with computed tomography (CT) function (ISO-C 3D; Siemens, Erlangen, Germany) in comparison to a conventional multi-slice CT scanner (LightSpeed QX/I CT; GE Healthcare, VA, USA).

Materials And Methods: A total of 10 intact femora with intact soft tissue of five fresh frozen cadavers were used. After fixation on a surgical table, IF CT scans of the hip and knee were performed at both 190° and 120° of scanning rotation.

Computer-assisted navigation of a complex femoral shaft fracture: instruction in three steps--a technical note.

The procedure of computer-assisted navigation of femoral shaft fractures is well described. Nevertheless, its use is less common. An unclear disposal and longer operation times might be two reasons.
