Radiographic, Surgeon and Owner Assessment of the BioMedtrix TATE<sup>®</sup>Elbow Arthroplasty

“…Radiological examination was performed by two independent observers (AN and NB) on two occasions 1 week apart. A protocol was followed to objectively measure component position, similar to that described by De Sousa and colleagues 17 and as illustrated in ►Fig. 5.…”

“…Discontentment with this system clinically has resulted in the development of several new total or partial arthroplasty systems [13][14][15] one of which is the TATE elbow system, a semi-constrained cementless bi-component resurfacing implant; 16 a recent retrospective study evaluating this system showed good clinical results in a majority of cases, but with a high complication rate. 17 Protocols for evaluation of component placement following arthroplasty have been shown in both human beings and dogs to be important in predicting the success of surgery as well as the risk of complications occurring. [18][19][20][21][22][23][24] Preliminary retrospective evaluation of TATE elbow component positioning has been performed by De Sousa and colleagues.…”

“…[18][19][20][21][22][23][24] Preliminary retrospective evaluation of TATE elbow component positioning has been performed by De Sousa and colleagues. 17 However, measurements were not standardized in this study, first due to radiographs that excluded the long axis of the humerus for measurement, and second, any effect of variable elbow flexion angle or positioning of the elbow on the measurement of component position was not evaluated. Any influence of elbow positioning on the measurement of TATE component position is important in developing a protocol for component position measurement that is accurate and repeatable, thus facilitating the objective correlation of component positioning with clinical outcome.…”

Objective The main purpose of this study was to evaluate the effect of varying elbow flexion angle and elbow orientation on the radiological measurement of component position for first (1G) and second-generation (2G) TATE elbow cartridges, and to test intra/inter-observer variability of measurements. Materials and Methods A cadaveric thoracic limb was implanted with a 1G then 2G cartridge, and mounted in lateral recumbency on an acrylic platform. The platform was tilted by set increments up to 10° in both planes, and radiographs were performed at each angle before repeating with the limb in caudocranial positioning. A deterministic trigonometric model was used to show how component angles should vary with changes in orientation, and these were compared with those measured by two observers. Humeral component angle (HCA), radioulnar component angle, varus/valgus cartridge alignment angle and the cartridge height:isthmus width ratio (CIR) were evaluated. Angles within 5° of the zero degrees inclination angle and ratios within 0.2 of the zero degrees inclination ratio were defined as acceptable. Results Observer component angles for both cartridges were accurate and precise for inclinations up to 10° except for HCA during adduction/abduction. The CIR values were within the acceptable limit for inclinations up to 7.5° in both planes. Clinical Significance Acceptable limits of limb inclination during positioning for TATE elbow replacement cartridge assessment were defined. All component measurements were sufficiently accurate and precise to be considered for evaluation of component position in clinical cases.

“…Currently, very few peer‐review publications relate to this system. Function was subjectively evaluated as acceptable in 76% of clinical cases, although perioperative complications, most of them major, occurred in 60% of cases . This high rate of complications justifies efforts to identify prognostic variables influenced by the surgeon, including operative technique.…”

Objective: To determine whether the surgeon can influence the accuracy of milling during the TATE elbow arthroplasty by applying force to the milling arm during the milling procedure. Study design: In vitro study on Sawbone specimens. Sample population: Thirty identical solid foam models of the canine right humerus, elbow joint, and antebrachium (size large). Methods: TATE elbow arthroplasty was performed on 30 elbows equally divided into 3 types of forces applied to the milling arm: (1) no force, (2) a maximally converging force, and (3) a maximally diverging force using the center of rotation post as a reference point. The resulting component-bone interface and post fit were quantified with digital photography. Results: The component-bone interface gap differed between techniques for most angles. The application of convergent or divergent milling forces frequently increased the component-bone interface gap. Post fit was also influenced by the milling technique, application of a convergent or divergent milling force affecting the fit of multiple posts. Interface gaps tended to be greater on the lateral aspect, an area that is not visible to the surgeon intraoperatively. Conclusion: In this bone model study, application of convergent or divergent forces during milling frequently resulted in greater component-bone interface gaps and poorer post fit than when a neutral position was maintained. Clinical significance: Surgeons may affect implant fit within the constraints of the current arthroplasty system if they do not maintain a neutral position during milling. Greater component-bone interface gaps and poorer post fit may affect component osseointegration and lead to aseptic implant loosening.
