Complications of Intramedullary Rods in Osteogenesis Imperfecta

Journal of Pediatric Orthopaedics, 1988
Twenty-nine patients with osteogenesis imperfecta underwent 108 intramedullary roddings with 42 Bailey-Dubow rods and 66 nonelongating rods. The average age at insertion of the first rod was 5 years; average follow-up was 3.1 years (range 1-9 years). The overall complication rate was 60%-69% for Bailey-Dubow rods and 55% for nonelongating rods.

Heterotopic Ossification After Femoral Intramedullary Rodding

Journal of Orthopaedic Trauma, 1993
Heterotopic ossification (HO) after femoral intramedullary rodding is a significant complication of the procedure. One hundred eighteen cases of femoral roddings performed on 113 patients were available for review. The data were computerized and evaluated using univariate analysis and multivariate regression analysis.

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 ...

Total Wrist Fusion Using an Intramedullary Rod Technique With Proximal Row Carpectomy.

Techniques in Hand & Upper Extremity Surgery, 2015
Intramedullary pin fixation is a common total wrist fusion technique, particularly for patients with rheumatoid arthritis. However, appropriate alignment of the proximal carpal row on the carpus can be challenging.

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.

Use of a Flexible Intramedullary Rod and its Influence on Patient Satisfaction and Femoral Size in Total Knee Arthroplasty.

Journal of long-term effects of medical implants, 2015
Improper femoral component size remains a source of multiple postoperative complications following total knee arthroplasty (TKA). However, the use of a flexible intramedullary (IM) rod may help optimize femoral component size and therefore improve ...

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.
