BIOMECHANICS OF THE KUNTSCHER INTRAMEDULLARY ROD

1982
ABSTRACT A kuntscher intramedullary rod has been instrumented with load and deflection cells to allow measurement of anterior-posterior bending, as well as compressive forces on the rod during insertion into cadaver femur specimens. Calibration of the devices has shown that high sensitivity (1.6 N/mv), linearity (± 2 %) and low crosstalk (> 8 ...

Retrieval and Analysis of Intramedullary Rods

Clinical Orthopaedics and Related Research, 1984
From 1980 to 1983, 16 AO intramedullary femoral rods were retrieved and analyzed clinically, radiographically, and metallurgically. Cracking and/or fracture was observed in four of the 16 specimens. All cracks occurred at the point of maximum stress at the end of the slot. In two cases a structurally weaker weld zone coincided with this location.

Hydroxylapatite and fluoroapatite coated intramedullary rods in canine femurs [PDF]

1993 IEEE Annual Northeast Bioengineering Conference, 2002
The effect of plasma sprayed synthetic calcium phosphate coatings, specifically hydroxylapatite (HA) and fluoroapatite (FA), on the degree of bone/implant attachment strength was investigated using a canine femoral intramedullary rod model. Titanium grit-blasted rods were implanted bilaterally, right side uncoated and the left side coated, in 12 ...

Removal of Intramedullary Rods After Femoral Shaft Fracture

Journal of Orthopaedic Trauma, 1992
We are reporting a retrospective review of the removal of 60 intramedullary rods in 58 patients. All fractures had healed at the time of rod extraction. The implant was removed from 34 asymptomatic patients (36 femurs). Twenty-four patients (24 femurs) had preoperative symptoms attributed to the femoral rod.

Anatomical Curvature of the Femoral Medullary Canal for Intramedullary Rodding

Journal of Biomechanics, 1987
The shape of most of the intramedullary and interlocking nails commonly used has been determined empirically as a segment of a circle. The radius of curvature of the Kuntscher nail, e.g., has a length of 3500 mm, the Aesculap-Kuntscher 3500 mm, the Grosse-Kempf 3000 mm, the AO 4000 mm, and the Klemm-Schellmann 3500 mm.

Curvature of the Femur and the Proximal Entry Point for an Intramedullary Rod

Clinical Orthopaedics and Related Research, 1987
The degree of anterior curvature of 14 human femurs and four currently marketed intramedullary rods was analyzed with the use of an interactive graphic computer program. The radius of curvature of the femurs ranged from 188.5 to 68.9 cm (average, 114.4 cm).

Femoral Shaft Nonunion Treated by a Fluted Intramedullary Rod

Clinical Orthopaedics and Related Research, 1985
Twenty-five consecutive nonunions or delayed unions of the femoral shaft were treated by a fluted intramedullary rod. Fourteen patients were men; 11 were women. Sixteen fractures represented failures of closed management. Five patients had failures of primary open reduction and internal fixation. Four patients had had one attempt at operative treatment

Closed Intramedullary Rodding of Pathologic Fractures with Supplemental Cement

Clinical Orthopaedics and Related Research, 1984
Internal fixation, supplemented with methylmethacrylate to fill bone defects, is the standard treatment for pathologic fractures. Unfortunately, internal fixation procedures often entail substantial blood loss and a not inconsequential risk of infection, problems with which the debilitated patient is poorly able to cope.

Treatment of Intertrochanteric and Subtrochanteric Fractures with Ender's Intramedullary Rods

Clinical Orthopaedics and Related Research, 1980
A series of 100 patients was treated with Ender's rods for intertrochanteric fractures, subtrochanteric fractures and intertrochanteric pathologic lesions. Healing occurred within 4 months in all 85 of the patients who could be followed, and fractures were prevented in all 4 of the patients with pathologic lesions.

Use of an Intramedullary Rod for the Treatment of Congenital Pseudarthrosis of the Tibia

The Journal of Bone and Joint Surgery-American Volume, 2005
The use of an intramedullary rod as described by Williams, combined with implantation of an autogenous bone graft, resulted in union of an established congenital pseudarthrosis of the tibia in nine of ten patients. One patient needed additional bone-grafting before union occurred.
