PURPOSE: There is an argument in the literature regarding the use of intramedullary nail or the external fixation followed by intramedullary nail in tibial fractures with severe damage of soft tissues, threatened compartment syndrome, open type IIIA fractures and in polytrauma patients. The purpose of this retrospective study was to evaluate the results of non-jointed external fixators as a definite treatment for these type of tibial shaft fractures.

MATERIAL AND METHOD: 86 patients (91 tibial shaft fractures) were treated at the authors’ institute with a non-jointed external fixator. The mean patient age was 35 years (range, 15–80). There were 70 male and 16 female patients. The average time of surgery from the accident was 10 hours. The indications for application an external fixator was: severe damage of the soft tissues in 11 fractures, an incipient compartment syndrome in 12 fractures, open type III Gustilo fractures in 57, and 11 tibia fractures in polytrauma patients. According to AO classification 46 fractures were type A, 32 type B and 13 type C.

RESULTS: The average follow up was 2.9 years (ranged, 1–5 years). The average operative time was 50 min. Complications included: 3 non-unions, 5 delayed unions, 1 malunions, 1 tibia shortening, 3 superficial infections of soft tissues in open fractures, 26 pin infections and 1 osteomyelitis in open fractures. In 2 patients fat embolism was diagnosed while pulmonary embolism was a complication in 2 patients. Deep venous thrombosis (DVT) developed in 5 patients. A re-operation was performed in 11 out of 91 fractures. Change of the method was necessary in 2 out of 91 fractures. The primary callus in 10 out of 91 fractures was due to the stiffness of the unilateral non-jointed external fixators and did not influence the final results. Mean time of fracture union for the open fractures that did not require change of the method nor bone graft was 25 weeks, while for the closed fractures was 18 weeks. The dynamization of the system and partial weight bearing was started at 6 weeks and all the patients had full weight bearing by the 12th week.

CONCLUSION: The unilateral external fixators were the definite treatment in 88 out of 91 fractures. The unilateral external fixators can be used as a definite treatment for tibial shaft fractures in the majority of the cases. Re-operation or change of the method is unusual and must be performed only when there is a delay in callus formation.

This study evaluates the results of our technique of proximal tibial osteotomy for treatment of osteoarthritis of the medial compartment of the knee.

One hundred and thirty eight knees were operated upon from 1981 to 1990. The degree of appropriate correction was measured in standing radiographs of the whole limb. Our technique consists of the creation of an osteotomy running obliquely just above the tibial tuberosity to the posterior tibial surface. No wedge is removed. Realignment is obtained by sliding the two osteotomy surfaces until the desirable correction is obtained. The osteotomy is fixed by a 90° blade-plate. By this technique precise correction can be achieved.

One hundred and seventeen knees were evaluated after a mean FU of 5, 5 years with 91% excellent or good result. In a second evaluation of 93 knees in a mean FU of 7.8 years, the good results dropped to 72%. In a third evaluation of 81 knees, after a mean FU of 11.8 years (range 9 to 16), only 54% of the knees maintained acceptable results.

The best results in the last evaluation were seen in 43 knees in which the postoperative alignment of femorotibial angle was 178° to 182°. Undercorrected or excessively overcorrected knees showed deterioration of the results in 4 to 9 years depending on the degree of mal-correction.

The results deteriorate with passage of time especially if precise correction is not achieved. Accurate preoperative radiographic measurements and precise operative technique is required to obtain exact correction of the axis in order to maintain the good results for a long period of time.
