To show the role and effectiveness of semi-constrained total elbow arthroplasty in restoring elbow function in severe, irreversible post-traumatic osseous and chondral injuries. Eighteen patients, aged 19–80, 11 male and 7 female, suffering from serious, irreversible anatomical and functional lesions of the elbow joint due to previous severe untreated or inadequately treated fractures (T-type transcondylar, trochlear-condylar, open fxs with large bony defects, severe osteochondral, heterotopic ossification in ICU fracture patients). Postop follow up was 9–57 months. All patients were treated with modular, cemented, semi-constrained linked total elbow arthroplasty. A functional brace was used post-operatively, and motion was permitted on the 3rd post-op day. The patients were allowed a full range of motion at 1 week post-op and they were subjected to vigorous physiotherapy. Post-op results were evaluated by using Mayo, DASH, quick-DASH scores and measuring grip strength and range of motion. Our results ranged from satisfactory to excellent in 16 patiens, with good strength and wide motion arc (with up to 15o extension-flexion deficit). One old female patient suffered a severe cerebral stroke with a bad outcome. In another young male patient the motion arc reached only 40% of the normal (spasticity, ICU patient with brain injury). Semi-constrained linked total elbow arthroplasty proves to be an effective method of treatment in severe, irreversible, intraarticular post-traumatic elbow injuries with chondral destruction and grave functional deficit, provided the proper technique is employed and a vigorous rehabilitation program is followed.
