“…The date range was 1950 to September 2020, with 1950 selected as the lower search limit since advances in HD prosthesis design occurred in this decade. 5 Boolean searching techniques were used and search keywords were ("hip disarticulation" OR "hemipelvectomy") AND ("amputee") AND ("prosthesis" OR "artificial limb" OR "socket" OR "design"). Studies were included if they evaluated HD or HP prostheses (retrospectively or prospectively) and were written in English.…”

“…In the 1950s, advances were made in HD prosthesis design by a Canadian rehabilitation engineer named Colin McLaurin. 5 He placed the hip joint anterior to the acetabulum, which positioned the center of gravity of the body posterior to the mechanical hip joint and anterior to the mechanical knee joint while standing (weight-bearing) and prevented the prosthesis from collapsing at the hip and knee. 5,6 Nevertheless, this prosthesis needed to be approximately 1 cm shorter than the intact leg to allow the prosthetic toe to clear the floor during swing phase.…”

To overcome the toe clearance limitation, a hip flexion bias system was developed in 1980 by Haslem.…”

Background: Although the global population of people with a hip disarticulation (HD) or hemipelvectomy (HP) amputation is small, the degree of disability is high, affecting function and independence. A comprehensive literature review is needed to examine the evidence for prostheses in these amputation levels. Method: A scoping literature review was conducted to examine related research documents from 1950 to September 2020, found using Scopus, Web of Science, PubMed, and Google Scholar databases. Studies evaluated (retrospectively or prospectively) HD or HP prostheses and were written in English. Study design and protocol, research instrument, sample size, and outcome measures were reviewed.Results: In the past 70 years, 53 articles that evaluated HD or HP prostheses were published. Most research was conducted in the United States (24 articles) and Japan (nine articles). In 42 articles, authors prospectively evaluated the effects of prostheses in these amputation levels. On average, prospective studies had four (SD 5 5) participants. Since 1950, only five prospective studies evaluated HD or HP prostheses with 10 or more participants. Moreover, sufficient information was often unavailable for research replication. Conclusion: More evidence is needed regarding the effects of HD or HP prosthetic components (i.e. hip, knee, ankle, socket type, and suspension system) on gait, patient satisfaction, prosthetic use, interface pressure, and energy expenditure. Articles mostly have small sample sizes that reduce confidence in the reliability of their findings and limit generalizability. Future investigations are needed with vigorous methodology and larger sample sizes to provide strong statistical conclusions.

“…Comfort, prosthetic control, weight, energy expenditure, balance, and stability are main concerns for people with such limb losses. [1][2][3] Moreover, hip-level amputee gait is more asymmetrical than in people with a lower amputation level, and the energy consumption could be up to 2 times more than in able-bodied individuals. [4][5][6][7] HD and HP prosthesis users experiencing asymmetrical gait leading to increased loads and stride times on the healthy limb are often due to a lack of muscular power and prosthetic component alignment.…”

People with a limb loss at the level of the hip or pelvis have the most difficulty returning to walking compared with those with a lower amputation. This is because their prosthesis must replace the hip, knee, and ankle joints. An adjustable hip-disarticulation/hemipelvectomy prosthesis simulator that allows able-bodied individuals to wear and assess a prosthesis can help researchers and manufacturers when designing new prosthetic components (ie, hip joints). SolidWorks computer-aided design software was used to design and simulate an adapter that can connect prosthetic components to an off-the-shelf hip abduction orthosis. The adapter was made of 1020 stainless steel and aluminium 6061-T3 with a yield strength of 276 MPa. To confirm that this adapter is strong and safe for ambulation, mechanical testing was performed using an INSTRON machine. The maximum loads generated in any activity were chosen according to the International Organization for Standardization 15032:2000 standard for hip disarticulation external prostheses. The designed adapter allowed frontal, lateral, or distal mounting of different prosthetic hip joints. Mechanical testing confirmed that the new adapter can withstand forces and moments experienced during ambulation. The hip disarticulation/hemipelvectomy prosthesis simulator is easy to use and adjustable based on each person’s height and pelvic width. Furthermore, this simulator would assist rehabilitation practitioners in experiencing the use of hip-level prostheses and give them a better understanding of people using such technologies. The next step in this project is to evaluate able-bodied participant gait while using this hip simulator prosthesis with different hip joints.

The Canadian type hip disarticulation prosthesis has been a significant improvement over the 'tilting table' design. In spite of its general use very little information on the patient/prosthesis performance exists. This paper describes an investigation carried out on three male patients. External load actions on the prosthetic and contralateral sides were measured simultaneously and synchronously with the configuration of the limb segments during level walking. Loading patterns at the ankle, knee and hip levels are presented and their significance discussed.
