Fonseca Ulloa C, Schreynemackers S, Harz T, Lang F, Folsch C, Rickert M, et al.
Clin Biomech (Bristol) . 2023 Aug; 109:106079. PMID: 37651899
Background: Preparing the medullary space of the femur aims to create an ideal form-fitting of cementless implants to provide sufficient initial stability, which is crucial for osseous integration, ensuring good...

Jahnke A, Kother-Herrmann J, Fonseca Ulloa C, Harz T, Rickert M, Ishaque B
Arch Orthop Trauma Surg . 2023 Jul; 143(11):6589-6597. PMID: 37418006
Introduction: Self-monitoring is crucial to work progressively with a high-quality standard. A retrospective analysis is a valuable tool for studying the postoperative outcome of a prosthesis and for evaluating the...

Rifer A, Stolz D, Fonseca Ulloa C, Harz T, Rickert M, Jahnke A
J Orthop . 2023 Jun; 41:57-62. PMID: 37333764
Background: Currently, the influence of muscle traction on the postoperative stability of humeral prostheses is not adequately researched. This study analyzed the prosthesis' stability during muscle traction considering different bone...

Fonseca Ulloa C, Seeger A, Hagedorn F, Harz T, Folsch C, Ishaque B, et al.
Med Eng Phys . 2023 Feb; 111:103932. PMID: 36792236
Aseptic loosening is a frequent cause for revision of endoprosthesis. X-ray examinations like Radio-Stereometry-Analysis (RSA) are among the most widely used in vivo methods for its detection. Nevertheless, this method...

Jahnke A, Muller F, Fonseca Ulloa C, Rickert M, Werner B, Gohlke F
Clin Biomech (Bristol) . 2021 Feb; 82:105283. PMID: 33524845
Background: Revision reverse shoulder arthroplasty (RSA) poses considerable surgical challenges. We hypothesized that a newly developed press-fit stem, which is modeled on the medullary canal of the supracondylar region of...

Fonseca Ulloa C, Seeger A, Ishaque B, Ahmed G, Rickert M, Jahnke A
Med Eng Phys . 2020 Dec; 86:122-127. PMID: 33261725
The continuous improvement of minimally invasive hip endoprostheses surgery comes with a change in geometries of surgery instruments like the broach handles. Consequently, depending on the handles' curvature this results...

Jahnke A, Ghandourah S, Fonseca Ulloa C, Seeger J, Rickert M, Ishaque B, et al.
J Biomech Eng . 2020 Jul; 142(12). PMID: 32601705
Cementless straight stems show very good survival rates. However, the more distal force application of straight stems may lead to release-related proximal stress-shielding. Nevertheless, this technical brief had the objective...

Jahnke A, Schroeder S, Fonseca Ulloa C, Ahmed G, Ishaque B, Rickert M
J Orthop Res . 2018 May; 36(10):2745-2753. PMID: 29744927
Aseptic loosening is the main reason for revision of total hip arthroplasty, and relative micromotions between cementless acetabular cups and bone play an important role regarding their comparatively high loosening...

Jahnke A, Fonseca Ulloa C, Seeger J, Rickert M, Jahnke G, Ahmed G, et al.
Clin Biomech (Bristol) . 2018 Jan; 52:49-56. PMID: 29360049
Background: The resultant hip force causes a varus torque which must be compensated by a shear force couple depending on the stem alignment of the prosthesis. Since the prosthesis is...
