[Quality of life after complex tibial reconstruction]. / Lebenszufriedenheit nach komplexen Unterschenkelrekonstruktionen.

58 patients following Gustilo IIIB open tibial fractures, treated by serial debridements, osteosynthesis and microvascular free tissue transfer were investigated after an average of 6 years. Assessment of life satisfaction was done by means of a proven valid and reliable test instrument (FLZ-"Fragen zur Lebenszufriedenheit"). Further specific questions on treatment satisfaction, aesthetic result, occupation and income were added to this questionnaire. Significant discrepancies of the items recreational activities, income, occupation and partnership, productivity, mobility and pain were evaluated in comparison to available data of healthy west german population. The calculated global index of life satisfaction and health differed significantly from the established index of west german population. Although specific aspects like aesthetic result, donor site morbidity, pain and even function were critically judged, 91% of the patients were satisfied with the long term result of the treatment. None of the patients thought that an initial amputation probably might have been a better solution. The postrehabilitation employment rate was 64%. Limb salvage of Gustilo IIIB fractures by means of a multidisciplinary treatment protocol is able to afford useful and satisfying long time results. However, an impairment of quality of life, at least in specific items has to be considered.

[The monorail system--bone segment transport over unreamed interlocking nails]. / Das Monorail-System--Knochensegmenttransport über ungebohrte Verriegelungsnägel.

A treatment protocol is demonstrated, consisting of an osteotomy, either proximal or distal, of the bone defect with subsequent segmental transport via an anteromedially (tibia) or laterally (femur) mounted AO external fixation over an unreamed interlocking nail (monorail system). Twenty patients were treated by this method with indications as follows: 13 had a segmental bone defect of the tibia, 3 of the femur. Three patients showed post-traumatic and postinfectious leg-length discrepancies and one was treated for hypertrophic non-union of the femur. Defect distance varied between 5 and 18.5 cm and average time for transport was 19,42 days/ cm for the tibial shaft, 15,93 days/cm for the femur. Two patients developed deep infection, which required change of treatment, removing the monorail system and application of an Ilizarov apparatus. Despite complications using the monorail system, all patients healed and no amputations were required. The monorail system can be used as an alternative to the Ilizarov method under certain criteria of patient selection; these criteria are shown by an algorithm for segmental bone defects without infection, respecting the soft-tissue status with or without neurovascular compromise.

Segmental transport after unreamed intramedullary nailing. Preliminary report of a "Monorail" system.

The Ilizarov method of segmental bone transport has been shown to be an alternative to more conventional treatments of posttraumatic bony defects. After extensive clinical experience with the unreamed tibial nail in open fractures up to Grade IIIb, a new monorail fixation system for callus distraction and segmental bone transport was devised. This Monorail system is composed of an unreamed intramedullary (IM) nail and a unilateral AO distraction device. The new fixation method and the preliminary clinical experience are reported here. Four patients who previously sustained Grades II-IIIb open tibial fractures had an average bony defect of 9 cm. Two patients had previous bony infections. All patients had had serial debridements and myocutaneous flaps were required in three patients. An unreamed IM nail was inserted, and the transport device was applied. After an osteotomy, segmental transport was carried out until docking was achieved. The external fixator was removed after interlocking of the transported segment. The mean duration of external fixation was 17.9 days/cm and the mean period until roentgenographic consolidation of the distraction and nonunion site was 41.2 days/cm. There were two pin-tract infections but no IM infections. One nail broke after osseous consolidation of the regenerate at the distal interlocking site and required exchange. The goal of transport was achieved in all cases without angular or rotational deformity or length discrepancy. There were no neurovascular injuries.
