AI Article Synopsis

  • The study aimed to determine standard mobility levels for lower limb amputation based on different causes, age, and amputation types (above and below the knee).* -
  • It involved 11,995 prosthesis users categorized into four groups: cancer, congenital, trauma, and diabetes/dysvascular, with mobility assessed using a specific survey.* -
  • Findings revealed significant mobility differences among age groups for various etiologies, which can help improve prosthetic rehabilitation goal-setting and future clinical practices.*

Article Abstract

Objective: The aim of the study was to establish normative values of lower limb amputation mobility across primary etiologies based on age and amputation level.

Design: This study is a cross-sectional observational analysis of outcomes. A total of 11,995 lower limb prosthesis users were included in the analysis. Participants were grouped by etiology into four categories: cancer, congenital, trauma, and diabetes/dysvascular. Mobility was assessed by using the Prosthetic Limb Users Survey of Mobility.

Results: Mobility across seven age groups for the four etiologies was established for both above-the-knee amputation and below-the-knee amputation. Differences were found between age groups for individuals: above-the-knee amputation: cancer (χ 2 (6) = 40.97, P < 0.001), congenital (χ 2 (3) = 9.41, P = 0.024), trauma (χ 2 (6) = 18.89, P = 0.004), and dysvascular (χ 2 (5) = 39.73, P < 0.001; below-the-knee amputation: cancer (χ 2 (6) = 29.77, P < 0.001), trauma (χ 2 (6) = 28.22, P < 0.001), and dysvascular (χ 2 (6) = 144.66, P < 0.001).

Conclusions: The awareness of differences across amputation etiologies extending across the lifespan of ages can assist the goal-setting process as part of prosthetic rehabilitation. In addition, refined normative values provide the ability to benchmark new and innovative changes in clinical practice.

Background: Thromboelastography (TEG) and coagulation tests can be used to detect hypercoagulability to assess thrombus formation. This study explored the association between TEG and coagulation in evaluating disease severity in elderly patients with lower extremity arteriosclerotic occlusive disease (LEASO), aimed to provide surgical treatment guideline.

Methods: We retrospectively analyzed the clinical characteristics, laboratory biomarkers, TEG and coagulation parameters of 233 elderly LEASO patients treated between 2020 and 2023.

Objective: To perform a systematic review of the utility of exoskeleton robotic therapy on lower extremity recovery in Spinal Cord Injury (SCI) patients.

Methods: We used the Embase, Cochrane, and PubMed databases and searched from to December 2023 for studies on exoskeleton robotic assist devices used in working with SCI patients. Only articles published in English were evaluated, and the retrieved articles were screened via our inclusion/exclusion criteria.

Myotonia congenita, both in a dominant (Thomsen disease) and recessive form (Becker disease), is caused by molecular defects in that encodes the major skeletal muscle chloride channel, ClC-1. This channel is important for the normal repolarization of muscle action potentials and consequent relaxation of the muscle, and its dysfunction leads to impaired muscle relaxation after voluntary or evoked contraction and muscle stiffness. More than 300 pathogenic variants have been found in association with congenital myotonia, inherited as recessive or dominant traits (with complete or incomplete penetrance).

Background: Modern techniques in lower extremity amputation have made significant advances to improve prosthetic control and soft-tissue envelopes through various techniques, including medial thighplasties. These advances are necessary to enhance the fit and functionality of the prosthesis in transfemoral amputations.

Methods: We performed a retrospective review of all thighplasties performed at our institution in patients with ipsilateral transfemoral amputation from November 2017 to December 2021.

Limb Salvage via Surgical Soft-tissue Reconstruction With Ovine Forestomach Matrix Grafts: A Prospective Study.

Plast Reconstr Surg Glob Open

December 2024

From the Department of Surgery, Associates in Medicine and Surgery, Fort Myers, FL.

Background: Complex and chronic lower extremity defects present a surgical challenge and can progress to eventual amputation if closure is not achieved. In addition to morbidity and mortality, these defects have a significant impact on patient quality of life and represent a substantial cost burden to the healthcare system. Ovine forestomach matrix (OFM) grafts are an advanced tissue scaffold option to supplement the surgical reconstruction ladder and may augment limb preservation in cases of complex lower extremity defects.
