Superior bone fixation of conical compared with hemispherical trapezial cup design: an experimental radiostereometry study

Abstract Purpose The most used cup designs for trapeziometacarpal (TMC) arthroplasty are of hemispherical and conical geometrical shape. Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). Methods Twenty saddle‐shaped pig forefoot bones were prepared with in...

520			\|a Abstract Purpose The most used cup designs for trapeziometacarpal (TMC) arthroplasty are of hemispherical and conical geometrical shape. Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). Methods Twenty saddle‐shaped pig forefoot bones were prepared with insertion of bone markers and reaming. Hemispherical Type T cups (Beznoska, Kladno, Czech Republic) (N = 10) and conical Moovis cups (Stryker, Pusignan, France) (N = 10) of 9‐mm diameter were inserted press‐fit. The bones were fixed in cement blocks for stability, and the cups were loaded in a motorized test stand. First, a low‐pressure cyclic load test (0—150N) with 130 compression cycles was performed. Next, a push‐in test of progressive loads with 50N increments (range: 150–900N) was applied until a visual change in cup position appeared. Cup migration was evaluated with RSA after every new load application. Cup failure was defined as total translation < 0.5 mm between two load applications. Results Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046). The Hazard ratio for failure was 0.52 (95% CI 0.12; 2.17) (p = 0.37), indicating that the risk of failure was two‐fold higher in the Type T group. Conclusion We conclude that conical TMC cups have superior fixation as compared to hemispherical cups above a loading level of 450 N, which correspond to a 3.8 kg tip‐pinch. In a clinical perspective, based on the fixation strength of both cup types, it seems safe to allow light‐load activities of daily living such as buttoning a shirt and using a key shortly after surgery and until sufficient osseointegration is achieved.

Results Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046). The Hazard ratio for failure was 0.52 (95% CI 0.12; 2.17) (p = 0.37), indicating that the risk of failure was two‐fold higher in the Type T group. Conclusion We conclude that conical TMC cups have superior fixation as compared to hemispherical cups above a loading level of 450 N, which correspond to a 3.8 kg tip‐pinch. In a clinical perspective, based on the fixation strength of both cup types, it seems safe to allow light‐load activities of daily living such as buttoning a shirt and using a key shortly after surgery and until sufficient osseointegration is achieved.

Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). Methods Twenty saddle‐shaped pig forefoot bones were prepared with insertion of bone markers and reaming. Hemispherical Type T cups (Beznoska, Kladno, Czech Republic) (N = 10) and conical Moovis cups (Stryker, Pusignan, France) (N = 10) of 9‐mm diameter were inserted press‐fit. The bones were fixed in cement blocks for stability, and the cups were loaded in a motorized test stand. First, a low‐pressure cyclic load test (0—150N) with 130 compression cycles was performed. Next, a push‐in test of progressive loads with 50N increments (range: 150–900N) was applied until a visual change in cup position appeared. Cup migration was evaluated with RSA after every new load application. Cup failure was defined as total translation < 0.5 mm between two load applications. Results Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046).

abstract	Abstract Purpose The most used cup designs for trapeziometacarpal (TMC) arthroplasty are of hemispherical and conical geometrical shape. Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). Methods Twenty saddle‐shaped pig forefoot bones were prepared with insertion of bone markers and reaming. Hemispherical Type T cups (Beznoska, Kladno, Czech Republic) (N = 10) and conical Moovis cups (Stryker, Pusignan, France) (N = 10) of 9‐mm diameter were inserted press‐fit. The bones were fixed in cement blocks for stability, and the cups were loaded in a motorized test stand. First, a low‐pressure cyclic load test (0—150N) with 130 compression cycles was performed. Next, a push‐in test of progressive loads with 50N increments (range: 150–900N) was applied until a visual change in cup position appeared. Cup migration was evaluated with RSA after every new load application. Cup failure was defined as total translation < 0.5 mm between two load applications. Results Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046). The Hazard ratio for failure was 0.52 (95% CI 0.12; 2.17) (p = 0.37), indicating that the risk of failure was two‐fold higher in the Type T group. Conclusion We conclude that conical TMC cups have superior fixation as compared to hemispherical cups above a loading level of 450 N, which correspond to a 3.8 kg tip‐pinch. In a clinical perspective, based on the fixation strength of both cup types, it seems safe to allow light‐load activities of daily living such as buttoning a shirt and using a key shortly after surgery and until sufficient osseointegration is achieved.

Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). Methods Twenty saddle‐shaped pig forefoot bones were prepared with insertion of bone markers and reaming. Hemispherical Type T cups (Beznoska, Kladno, Czech Republic) (N = 10) and conical Moovis cups (Stryker, Pusignan, France) (N = 10) of 9‐mm diameter were inserted press‐fit. The bones were fixed in cement blocks for stability, and the cups were loaded in a motorized test stand. First, a low‐pressure cyclic load test (0—150N) with 130 compression cycles was performed. Next, a push‐in test of progressive loads with 50N increments (range: 150–900N) was applied until a visual change in cup position appeared. Cup migration was evaluated with RSA after every new load application. Cup failure was defined as total translation < 0.5 mm between two load applications. Results Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046). The Hazard ratio for failure was 0.52 (95% CI 0.12; 2.17) (p = 0.37), indicating that the risk of failure was two‐fold higher in the Type T group. Conclusion We conclude that conical TMC cups have superior fixation as compared to hemispherical cups above a loading level of 450 N, which correspond to a 3.8 kg tip‐pinch. In a clinical perspective, based on the fixation strength of both cup types, it seems safe to allow light‐load activities of daily living such as buttoning a shirt and using a key shortly after surgery and until sufficient osseointegration is achieved.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Trapeziometacarpal
