Force transmission capacity of the lower limb during walking of amputees with bone-anchored prostheses compared with socket prostheses and persons with hip replacements.

Background: Restoring the ability to walk with a prosthesis is considered a fundamental rehabilitation goal after transfemoral amputation. An essential prerequisite for achieving this goal is adequate force transmission between the prosthesis and the body. Does bone anchorage of an artificial limb permit a more normal force transmission?

Methods: Data of 15 healthy subjects, nine amputees fitted with bone-anchored prostheses, nine amputees using socket prostheses, and 18 patients with a total hip replacement were included in this multicenter, observational study.

Comparison of conventional socket attachment and bone-anchored prosthesis for persons living with transfemoral amputation - mobility and quality of life.

Background: For patients with transfemoral amputation experiencing issues with their sockets, bone-anchored prosthesis systems are an alternative and sometimes the only way to be mobile and independent. The present cross-sectional study aimed to investigate the gait performance and quality of life of a group of patients treated with bone-anchored systems compared to those of participants treated with a conventional socket-suspended prosthesis.

Methods: A total of 17 participants with a socket-suspended and 20 with a bone-anchored prosthesis were included.

Twenty-four months of bacterial colonialization and infection rates in patients with transcutaneous osseointegrated prosthetic systems after lower limb amputation-A prospective analysis.

Background: Transcutaneous osseointegrated prosthesis systems (TOPS) are alternative rehabilitation methods to socket prosthetics, after limb amputation. TOPS compromise a two-step surgery: starting with the implantation of the stem which is then followed by the creation of the transcutaneous stoma through which the exoprosthesis can be connected. Immediately after surgery, this opening is permanently exposed to pathogens.

Elective transfemoral amputation and simultaneous implantation of a transcutaneous osseointegrated prosthesis stem as salvage treatment after knee joint arthrodesis with poor function: A case report.

Background: Surgical reconstruction of anterior cruciate ligament ruptures is a well-established procedure, and although it is for the vast majority of patients without severe complications, total knee joint arthroplasty, arthrodesis of the knee, and finally transfemoral amputation have to be considered in the worst-case scenario.

The Case: We report a case of a patient with a 13-year history of recurrent failure after anterior cruciate ligament reconstruction. She claimed she had severely impaired mobility secondary to a knee joint arthrodesis an Ilizarov circular frame 2 years ago and chronic immobilizing pain, making a permanent medication with opioids necessary.

Analysis of Stomal Bacterial Colonialization After Transcutaneous Osseointegrated Prosthetic Systems Surgery.

This cohort study evaluates bacterial colonization of the stoma after transcutaneous osseointegrated prosthetic systems surgery.

Comparison of functional outcome and patient satisfaction between patients with socket prosthesis and patients treated with transcutaneous osseointegrated prosthetic systems (TOPS) after transfemoral amputation.

Purpose: The aim of this retrospective analysis was to investigate and evaluate differences in functional outcome and satisfaction of patients treated with a TOPS and patients using socket prosthesis after transfemoral amputation.

Methods: This retrospective comprehensive analysis included patients from a single hospital, and was conducted between February 2017 and December 2018. Overall n = 139 patients with prosthesis were included and divided into two comparable groups (socket- and TOPS group).

Osseoperception in transcutaneous osseointegrated prosthetic systems (TOPS) after transfemoral amputation: a prospective study.

Background: Endo-exo prosthetics (EEP), which belongs to the transcutaneous osseointegrated prosthetic systems (TOPS), provides an alternative bone-anchored rehabilitation method for transfemoral amputees. It led to the question of whether transmitted forces from prosthetic feet are perceptible by osseoperception resulting in proprioceptive feedback of ground conditions.

Objectives: The following hypotheses emerged for our trial with the null hypothesis: EEP fitting after transfemoral amputation does not influence osseoperception.

Quality of life of persons with transfemoral amputation: Comparison of socket prostheses and osseointegrated prostheses.

Background: Until recently, no study had compared the quality of life of persons with transfemoral amputation treated with osseointegration to socket prosthesis users.

Objectives: Comparison of quality of life in two types of prostheses users: a cohort of patients with osseointegration and patients equipped with a socket prosthesis who were group-matched for age, body mass index and mobility grade.

Study Design: A cross-sectional study that compared METHODS:: The quality of life of 39 participants (22 in the osseointegration group and 17 in the socket prosthesis group) was measured using the Questionnaire for Persons with Transfemoral Amputation (Q-TFA) and European Questionnaire 5-dimension 3-level (EQ-5D-3L) surveys.

Management, outcome, and novel classification system of periprosthetic fractures in patients with transcutaneous osseointegrated prosthetic systems (TOPS)-a retrospective cohort analysis.

Introduction: Transcutaneous osseointegrated prosthetic systems (TOPS) are anchored prosthetic systems for major limb loss. Sometimes TOPS patients suffer from periprosthetic fractures. The aim of this study was to analyze the management and outcomes of periprosthetic fractures in patients with TOPS and to introduce a novel classification system for this entity.

Preoperative femoral abduction angle correlates with initial postoperative lateral hip pain after transcutaneous osseointegrated prosthetic system (TOPS) in transfemoral amputees.

Purpose: To analyse whether a preoperative femoral abduction angle (FAA) correlates with postoperative initial lateral hip pain (LHP) in above-knee amputees (AKA) treated with transcutaneous osseointegrated prosthetic system (TOPS).

Methods: Pre- and postoperative long-leg radiographs of eighteen unilateral AKA (mean age 51.55y ± 12.

[Transcutaneous osseointegrated prosthetic systems after major amputation of the lower extremity : A retrospective 3-year analysis].

Introduction: Transcutaneous osseointegrated prosthetic systems (TOPS) are an established optional procedure for the prosthetic treatment of amputations. Under the term endo-exo-prosthesis (EEP), the endosteal adapted exo-prosthesis (Dr. Grundei®) is currently used as the only standard prosthesis for clinical application in Germany.

[Transcutaneous Osseointegrated Prosthetic Systems (TOPS) for Transfemoral Amputees - A Six-Year Retrospective Analysis of the Latest Prosthetic Design in Germany].

Purpose: A retrospective analysis of clinical outcomes and complication rates of patients treated with the latest implant design of the so-called Endo-Exo-Femoral Prosthesis (EEFP) was performed. The aim is to gain specific information on long-term complications of this treatment-method.

Methods: In January 2019, data of all transfemoral amputees who were treated with TOPS at an acute clinic in Schleswig-Holstein from 2010 to 2016 were retrospectively analysed.

Three-year follow-up of changes of cortical bone thickness after implantation of Endo-Exo-Prosthesis (EEP) for transfemoral amputees.

Introduction: Transcutaneous Osseointegrated Prosthetic Systems (TOPS) offer a good alternative for patients who cannot be satisfactorily rehabilitated by conventional suspension sockets. The Endo-Exo-Prothesis (EEP, ESKA Orthopaedic Handels GmbH®, Deutschland) is the most implanted TOPS in Germany. Previous studies have shown that cortical thickness increases after implantation of TOPS.

This is a retrospective review of medical case for a patient who had a previous above-the-knee amputation secondary to a failed previous arthroplasty surgery. Our planned surgery was a stage 1 implantation of an Endo-Exo-Prosthesis, and it was performed under general anaesthesia.

[Transcutaneous osseointegration after limb amputation : A review over 27 years].

Intramedullary, bone-anchored (osseointegrated), transcutaneous docking of artificial limbs has been in clinical use for more than 25 years. This system of prosthetic limb attachment is a valuable treatment option in the rehabilitation of patients after limb amputation. Only a few centers are systematically investigating this topic worldwide so that current knowledge on this special treatment option is still limited; however, mainstream medical opinion still regards percutaneous skeletal prosthetic docking with some skepticism.
