In adults with an acquired unilateral upper extremity amputation, how do cumulative healthcare costs, healthcare service utilization, and functional outcomes over the first five years compare between patients fitted with a prosthesis and those without a prosthesis?

Prosthesis Fitting in Unilateral Upper-Limb Amputation: Healthcare Costs, Utilization, and Functional Outcomes

Adults with acquired unilateral upper-limb amputation who are fitted with a prosthesis demonstrate significantly better functional outcomes and reduced disability compared to those without prostheses, though specific data on cumulative 5-year healthcare costs and service utilization for this population remains limited in the available evidence.

Functional Outcomes: Clear Advantage with Prosthesis Use

The evidence strongly supports prosthesis fitting based on functional outcomes:

Prosthesis users consistently demonstrate superior function across multiple domains. Non-users report significantly worse disability scores, with QuickDASH scores approximately 9.4 points higher (indicating worse function) compared to body-powered prosthesis users 1. This translates to meaningful clinical differences in daily life—non-users have 1.84 times higher odds of requiring help with activities of daily living compared to body-powered prosthesis users 1.

Activity Performance and Participation

• Prosthesis receipt is associated with improved ability to participate in social roles and activities (baseline score: 41.5 improving to 46.7 at follow-up, p<0.001) 2
• Pain interference significantly decreases with prosthesis use (baseline: 58.5 improving to 54.9, p<0.001) 2
• Patients not using prostheses experience more difficulty performing one-handed tasks with the residual limb compared to body-powered prosthesis users 1
• Among prosthesis users, 17 of 18 patients achieved sufficient proficiency to return to work, with 15 maintaining daily functional use of at least 8 hours 3

Prosthesis Type Matters

The functional hierarchy is clear:

• Body-powered and myoelectric prostheses provide superior functional outcomes compared to cosmetic devices 1
• Cosmetic device users report more task difficulty than body-powered or myoelectric users 1
• Functional prostheses providing proprioceptive feedback improve pain, function, and embodiment through cortical reorganization 4

Healthcare Costs: Limited Direct Evidence

The available evidence does not provide specific 5-year cumulative cost comparisons between prosthesis users and non-users in upper-limb amputation. However, relevant cost considerations include:

• One study examining both upper and lower extremity amputations found per-patient direct healthcare costs of approximately $59,847, with overall per-patient costs reaching $89,808 5
• Psychosocial factors (PTSD, anxiety) increase prosthetic management costs 6
• The cost data available does not differentiate between prosthesis users versus non-users or provide longitudinal 5-year tracking specific to unilateral upper-limb amputation

Important Cost Context

While direct cost comparison data is lacking, the functional benefits of prosthesis use likely translate to reduced indirect costs through:

• Decreased need for assistance with ADLs (reducing caregiver burden)
• Higher rates of return to work
• Reduced pain interference requiring fewer pain management interventions

Healthcare Service Utilization: Evidence Gap

No studies in the provided evidence directly compare healthcare service utilization patterns over 5 years between prosthesis users and non-users in unilateral upper-limb amputation. This represents a significant knowledge gap in the literature.

Clinical Recommendations Based on Available Evidence

Prosthesis Fitting Should Be Standard Practice

All patients with upper-limb amputation should be fitted with an appropriate prosthesis 6. The AAOS guidelines explicitly state "there is no question that ambulatory potential is improved with a prosthesis after amputation" (though this refers to lower extremity, the principle applies) 6.

Timing and Training Are Critical

• Early prosthetic fitting (within 30 days) combined with comprehensive training yields optimal outcomes 3
• Patients achieving prosthetic proficiency show high rates of sustained daily use (8+ hours) 3
• Approximately 80.8% of upper-limb amputees wear prostheses when properly fitted 7

Multidisciplinary Approach Required

Beyond prosthetic fitting, patients require:

• Evaluation for psychosocial risk factors (PTSD, anxiety, low self-efficacy) as these significantly impact outcomes and costs 6
• Physical and occupational therapy 6
• Behavioral health interventions 6
• Long-term follow-up to assess device adequacy 6

Critical Caveats

The major limitation is that available guidelines focus primarily on lower extremity trauma 6, while the question specifically addresses upper-limb amputation. The functional outcome studies for upper-limb amputation 1, 7, 8, 3, 2 consistently support prosthesis use, but comprehensive 5-year cost and utilization data comparing users versus non-users is not available in the current evidence base.

The most recent and relevant functional outcome data 2 (2026) demonstrates clear benefits of prosthesis receipt, but this study does not address the specific cost and utilization questions posed. In the absence of definitive cost-utilization data, the clinical decision should prioritize the well-established functional benefits and quality of life improvements associated with prosthesis use.
