The introduction of the Gamma nail (GN) as an intramedullar implant for pertrochanteric femoral fractures that allowed full weight bearing decreased the death rate from 17% (methods without full weight bearing) to 6%. The long Gamma nail (LGN) is a logical supplement of the standard version, designed to treat unstable per-, subtrochanteric and segmental fractures. This study evaluated 44 consecutive operations. Seventy percent of the patients had to be classified ASA III and IV, due to their high morbidity. The median age was 73.5 years. Multiple injuries occurred in 30.2%. All fractures were considered unstable. Surgery was usually performed within 24 h. The median duration of the surgical treatment was 120 min. In five cases technical problems were observed. Radiological controls showed a good positioning of the head screw. Early complications consisted of four local wound infections, three of them deep infections with a osteomyelitis. Deep venous thrombosis was observed in four cases, two of which included a pulmonary embolism (conservative treatment). The 30-day death toll was 2.3% (one patient). The median survival time (using Kaplan-Meier) in the study was 46 months, compared to 80 months in a matched population. This difference has to be linked to high premorbidity. The median duration of admission was 15 days. Mobilisation with full weight bearing was theoretically possible in all cases, but additional injuries or preoperatively impaired walking ability prevented full mobilisation in 15 cases. Functional assessment uncovered a decrease in Merle d,Aubigne score of 26.7% due to an impaired walking ability. Seventy-three percent of the patients regained their preoperative social status. In conclusion the long Gamma nail is a universal, less invasive implant with high early weight bearing. It thus allows early remobilization and reduces lethality in the treatment of complex, unstable coxal fractures.
