Awareness, potential factors, and post-amputation care of stump flexion contractures among transtibial amputees

Case Report: Total Knee Arthroplasty in Ipsilateral Below-Knee Amputee

Introduction

Total knee arthroplasty (TKA) has the highest annual incidence among all joint replacement surgeries. Below-knee amputation (BKA) is another common procedure to treat lower-limb-threatening pathologies. These two procedures are commonly performed individually, but an ipsilateral TKA performed on a BKA patient is rare. While ipsilateral amputation is not a contraindication for TKA, it presents orthopaedic surgeons with a unique case and necessitates thoughtful pre-operative planning regarding proper positioning, alignment determination, surgical technique, and rehabilitation for the best outcome.

Objectives

We present a case of a patient with a BKA who underwent ipsilateral TKA.

Case Report

This patient has a history of osteoarthritis (OA) of the right knee and diabetic neuropathy and underwent a right BKA after sustaining second-degree thermal burns to the bilateral forefeet. The patient was scheduled to undergo elective TKA prior to these injuries but was forced to postpone due to their severity. Following the BKA, the patient regained his ability to ambulate independently with prosthesis but continued to suffer from OA symptoms. The patient was then scheduled for surgery, and a TKA was performed.

Conclusion

The patient underwent a TKA and tolerated the surgery well without complications. Appropriate positioning was achieved using a popliteal post. Alignment and tibial cut were checked using fluoroscopy. All components were cemented into position, and the patella was resurfaced. The patient did well postoperatively and was using his prosthesis and ambulating independently at the final follow-up.

Botox in below knee amputation for the management of post-operative contracture: a systematic review

During the 1970s, scientists first used botulinum toxin to treat strabismus. While testing on monkeys, they noticed that the toxin could also reduce wrinkles in the glabella area. This led to its widespread use in both medical and cosmetic fields. The objective of the study was to evaluate the potential use of Botox in managing post-operative contracture after below-knee amputation. We conducted a systematic review In Pubmed, Cochrane Library, Embase, and Google Scholar using the MESH terms Botox, botulinum toxin, post-operative contracture, amputation, and below knee amputation. Our goal was to evaluate the potential use of Botox to manage post-operative contracture in patients who have undergone below-knee amputation. Our findings show evidence in the literature that Botox can effectively manage stump hyperhidrosis, phantom pain, and jumping stump, but no clinical trial has been found that discusses the use of Botox for post-operative contracture. Botox has been used in different ways to manage spasticity. Further studies and clinical trials are needed to support the use of Botox to manage this complication.

Factors associated with joint contractures in adults: a systematic review with narrative synthesis

PURPOSE

The primary objective of the review was to collate the available evidence on factors associated with joint contractures in adults.

METHODS

A systematic literature search was conducted on MEDLINE, CINAHL, AMED, and EMBASE. Studies that involved participants aged ≥18 and assessed joint contracture as a primary or secondary outcome were included. Two independent reviewers screened studies against the eligibility criteria, performed data extraction, and assessed the quality of evidence. A narrative synthesis by domain and sub-domain was undertaken. The protocol was registered on PROSPERO: CRD42019145079.

RESULTS

Forty-seven studies were included in the review. Identified factors were broadly classified into three major domains: sociodemographic factors, physical factors, and proxies for bed confinement. Sociodemographic factors were not associated with joint contractures. Functional ability, pain, muscle weakness, physical mobility, and bed confinement provided the most consistent evidence of association with joint contractures. The evidence regarding the relationship between spasticity and joint contractures remains unclear. Other factors might be important, but there was insufficient evidence to make inferences.

CONCLUSIONS

The review identified and collated evidence on factors associated with joint contractures, which can be utilised to develop effective prevention and management strategies. Implications for rehabilitationClinical interventions based on the timely identification of risks related to joint contractures in vulnerable adults have the potential to prevent or ameliorate their development or progression.Quality and consistency of care for vulnerable adults would be enhanced by developing effective joint contracture prevention and rehabilitation strategies based on the evidence presented in this review.As many vulnerable adults are located in the community or non-acute care settings, strategies should target these loci of care.Structured risk assessments that can support non-physiotherapy staff working in these loci of care to identify risks related to joint contractures would provide an important resource for risk management.

Self-Management in Persons with Limb Loss: A Systematic Review

BACKGROUND

Self-management is an integral component of managing long-term conditions and diseases. For a person with limb loss, this self-management process involves caring for the residual limb, the prosthesis, and the prosthetic socket-residual limb interface. Failure to properly self-manage can result in unwanted secondary complications such as skin breakdown, falls, or non-use of the prosthesis. However, there is little evidence on what self-management interventions are effective at preventing secondary complications. To understand the impact of self-management after the loss of a limb, it is necessary to determine what the current evidence base supports.

OBJECTIVES

The purpose of this study is to examine the available literature on self-management interventions and/or outcomes for persons with limb loss and describe how it may impact residual limb health or prosthesis use.

METHODOLOGY

A systematic review of multiple databases was carried out using a variety of search terms associated with self-management. The results were reviewed and selected based on the inclusion criteria: self-management interventions or direct outcomes related to self-management, which includes the skin integrity of the residual limb, problem-solving the fit of the prosthesis, and education in the prevention of secondary complications associated with prosthesis use. The Cincinnati Childrens' LEGEND (Let Evidence Guide Every New Decision) appraisal forms were used to analyze the articles and assign grades.

FINDINGS

Out of the 40 articles identified for possible inclusion in this study, 33 were excluded resulting in seven articles being selected for this review. Three out of the seven articles focused on silicone liner management while the other four articles focused on skin issues.

CONCLUSIONS

Self-management for a person with limb loss is a key component of preventing complications associated with loss of limb and prosthesis use. There is a lack of high-quality experimental studies exploring the most appropriate intervention for teaching self-management when compared to other conditions, specifically diabetes. Further research in the area of self-management is necessary to understand how to best prevent unwanted secondary complications.

Fitting transtibial and transfemoral prostheses in persons with a severe flexion contracture: problems and solutions - a systematic review

PURPOSE

In persons with a hip or knee flexion contracture ≥25°, fitting a prosthesis is said to be difficult. This systematic review aims to assess the evidence for fitting of a prosthesis in persons with a severe contracture (≥25°) after a lower limb amputation.

METHOD

PubMed, Embase, Scopus, CINAHL, and Orthotics & Prosthetics Virtual Library databases were searched from inception to December 2019, using database specific search terms related to amputation, prosthesis, and contracture. Reference lists of included studies were checked for relevant studies. Quality of the included studies was assessed using the critical appraisal checklist for case reports (Joanna Briggs Institute).

RESULTS

In total, 13 case studies provided evidence for fitting of a prosthesis in more than 63 persons with a transtibial amputation and three with a transfemoral amputation, all of whom had a hip or knee flexion contracture ≥25°. Some studies found a reduction in contractures after prosthesis use.

CONCLUSIONS

Several techniques for fitting a prosthesis in case of a flexion contracture ≥25° were found. Contracture reduction occurred in some cases and was possibly related to prosthesis use. Fitting a transtibial or transfemoral prosthesis in persons with a lower limb amputation with a severe flexion contracture is possible.IMPLICATIONS FOR REHABILITATIONThis study provides information on prosthesis prescriptions and adaptations for persons with a transfemoral and transtibial amputation with a flexion contracture ≥25°.The fitting of bent prostheses is not limited by prosthetic components and techniques.Parallel to the use of bent prostheses, it is also important to treat the contracture.
