Table 3 Studies on non-prosthesis induced risk factors for DTI

From: Exploring the role of transtibial prosthetic use in deep tissue injury development: a scoping review

Author and yearType of StudyObjectiveNon-prosthesis induced risk factorsStudy PopulationQualitative Results
Henrot et al. 2000 [39]Literature reviewOverview over surgical features of amputation in relation to postoperative stump painTissue MorphologyNA- Postoperative complications: Heterotopic ossification, aggressive bone edges, pistoning, ulceration
- Extrinsic pain: caused by improper fit or alignment
- Intrinsic pain: nervous or anatomical cause
Portnoy et al. 2007 [37]In silico studyDetermination of internal stress in muscle flap of TTAa; influence of bone sharpness, tissue thickness, mechanical propertiesTissue Morphology,Mechanical Properties- Use of data from Portnoy et al. 2007 [29]- Increase in pressure with reduced flap thickness
- Increase in pressure with increased muscle stiffness
- No clear relationship between bone radius and pressure
Portnoy et al. 2009 [30]Experimental studyDetermination of inter-subject variability in internal tissue loads in TTA with different geometrical features during static loadingTissue Morphology- 5 unilateral TTAs
- Traumatic cause
- 1 female, 4 male
- Mean age 48.6 yrs.
- Mean weight 67.8 kg
- High inter-subject variability
- Risk of DTI for patients with little fat padding
- More even pressure distribution with flat compared to sharp tibial ends
- Lower strains with longer residua
Portnoy et al. 2009 [36]In silico studyIdentify influence of risk factors on internal loadingonditions in TTATissue Morphology,Mechanical Properties- 1 unilateral TTA
- Traumatic cause
- Male
- Age 44 yrs.
- Weight 82 kg
- Thicker muscle flap and increased bone radius reduce DTI risk
- Osteophyte, sharp bevelment and muscle stiffening increase risk
- Surgical scars change overall stress distribution
Kosasih et al. 1998 [28]Experimental studyIdentify sensory changes in well healed TTAsSensory impairment- 9 unilateral TTAs
- Traumatic cause
- All male
- Mean age 55.4 yrs.
- Weight not specified
- No deep pressure sensory impairment in well healed TTA stumps
Mak et al. 2001 [40]Literature reviewOverview over current knowledge on biomechanics in TTAsSensory impairmentNA- Neuropathy leading to usually preventable soft tissue damage
Bader et al. 2019 [26]Literature reviewAnalysis of bioengineering tools for device related soft tissue damageSensory impairmentNA- Risk factors: neuromuscular impairments, diabetes
