Aims: To evaluate the functional recovery of the complex tibial plateau fractures Schatzker type V and VI treated with hybrid ex. fix..

Methods: Twenty-eight patients with intra-articular fractures of the proximal tibia were treated with hybrid external fixation in a three years period (1998–2001).The mean age was 35 years (17–76). According to Schatzker classification, there were 11(39.3%) fractures type V and 17(60.7) type VI, whereas 5(17.8%) fractures were open. Complex injury was recorded in 15(53.5%) patients. Closed reduction and hybrid external fixation was achieved in 21 (75%) fractures. Additional limited internal fixation was performed in 9(32%) cases. Open reduction was necessary in 7(25%) patients. Mobilization of the injured articulation was started at the 3rd postoperative day.

Results: Mean follow up period was 18 months. All fractures but one united at an average of 13.5 weeks (range from 11 to 18 weeks). The results were assessed according to the criteria of Honkonen and Jarvinen. An overall 22(78%) excellent and good results was recorded at the final follow up. Complications included one axial deformity, one septic pseudarthrosis, one peronial palsy and five pin tract infections.

Conclusions: The use of hybrid external fixation in the comminuted tibial plateau fractures (Schatzker V,VI), insure good restraining and early union, avoid major soft tissue complications and allow early mobilization and functional recovery of the knee joint.

Aim: A comparison of two different techniques of acro-mioclavicular joint reduction in complete AC disruption.

Methods: During 1992–2001, 59 patients (50 male; 9 female; average 32.3y), underwent surgical reconstruction for complete (Allman-Tossy III) AC dislocation. Fixation of the joint was achieved in all patients by double-banded coracoclavicular stabilization, using heavy nonabsorbable sutures in a double-banded ligamentous substitution manner. In 35 patients (group I) a temporary acromioclavicular fixation was done (with K-W, removable at 6th postoperative week), whereas in the rest 24 patients (group II) an additional fixation of the acromioclavicular disruption, with nonabsorbable sutures, without using K-W was performed.

Results: Mean follow-up period was 6.4 years. Our results according to Constant-Murley score were excellent or very good in 25 patients (71.4%) of group I and 21 (87.5%) patients of group II. Loss of reduction (3), calcification (5) and superficial pin infection (2) were noted with greater frequency in patients of group I. Three of them reoperated because of K-W migration or breakage. Complications of group II included 1 superficial infection, 1 calcification with restriction of joint motion and 1 case with slight loss of reduction.

Conclusions: Reduction of the acromioclavicular joint in association with adequate retention of the coracoclavicular joint are the cornerstones for a good surgical result. Double banded coracoclavicular fixation and acromio-clavicular repair with heavy nonabsorbable sutures and no use of K-W, seems to be the best surgical technique provided adequate stabilization of acromioclavicular joint, preservation of clavicular rotation, no risk of implant migration and no need of material removal.

To investigate the potential of biological fixation of cementless total hip prosthesis in patients over 75 years old, with diagnosed osteoporosis.

Between 1994–2000, 30 patients (mean age 77.3 years) underwent total hip arthroplasty (THA). Twenty-two (22) patients, 10 male and 12 female, were found at the last follow-up, which ranged from 1, 5–7 years (mean follow-up, 3 years). THA was performed due to primary osteoarthritis (n=16), subcapital fracture (n=4), or dysplastic hip (n=2). Eight (8) smooth, tapered design (CLS) and 14 proximally porous coated prostheses were implanted. Smgh index was used for the evaluation of osteoporosis and modified Harris Hip Score was used for the clinical evaluation of each patient. Modified Wixon score was used for the evaluation of stability probability of the tapered stem. Engh score was calculated for the evaluation of osseointegration of the porous coated implants.

Pre and post-operative mean Singh index was grade 4. Mean modified Harris Hip Score at the last follow-up was 88.6. For the CLS-Spotomo stem a stable fixation probability was calculated at 74.8%, while possible instability was calculated at 48.17%. Porous coated stems provided +13.45 mean. Engh score, implying satisfactory fixation of the implant. Post-operative systematic complications are not reported, in contrast to 3 dislocations in the first post-operative period, which were treated by closed reduction.

In patients over 75 years old, with possible cardiopulmonary disease, cementless total bip arthroplasty offers a reliable treatment, regardless the presence of osteoporosis. Satisfactory osseointegration and absence of systematic complications is compromised by the high cost of titanium implants.
