Aim: To study the postoperative results of an alternative method of pin placement for acute pelvic ring stabilization with an external fixation.

Introduction: External fixation for stabilization of pelvic ring fractures is the only and a safe method for emergency treatment. According to literature pins of the fixator should be placed urgently on the superior iliac rim and as soon as general condition of the patient permits, revision is required in order to manage in a finitive way the injury.

Material-Method: Inclusion criteria were high energy trauma, severe pelvic instability, heamodynamic instability, acute management of a pelvic fracture and minimum follow up of 2 years. Patients with a simultaneus major head, chest or abdominal injury were excluded from the study. Between 2000–01, 19 patients (15 male and 4 female with a mean age of 28 years old) underwent acute pelvic stabilization with an external fixation. In 12 patients, mechanism of injury was road accident and in 7 patients a fall from a height. Fracture type according to Tyle classification was 2 type A, 12 type B and 5 type C. In 6 patients the pins were placed in an oblique plane to the superior iliac rim (Group I) and in 13 patients there were placed in the sagital plane, just below the superior anterior iliac spine (Group II). The mean time for external fixation application was 15 min for group I and 22 min for group II.

Results: 14 patients were heamodynamically stabilized in the early postoperative period and 5 patients were transmitted to Intensive Care Unit. In 17 patients a rigid fixation of the pelvis was achieved and remained as a definite method of treatment and in 2 patients of Group I, replacement of the external fixator and an adjacent stabilization of posterior elements was required. No patient required adjacent posterior element stabilization as the primary reduction and stabilization was satisfactory. Mean time of stabilization was 7 weeks for type A, 10 weeks for type B and 11 weeks for type C fractures. 13 patients were totally recovered and returned to their previous occupation and 6 patients have minor problems that are attributed to the pelvic ring fracture.

Conclusions: External fixator’s placement for pelvic ring stabilization should be performed in a way that it will be a finitive method for osteosynthesis of the pelvis. We suggest pin placement in the sagital plane, below the superior anterior iliac spine instead of placement at the superior iliac rim.

We report our experience on complications of intra-medullary nailing on 150 femoral shaft fractures.

Material concerns 147 patients (103 men and 44 women) that were operated in a 7 years period. Mean age was 37 years old (15–77). Thirty patients were older than 65 years. Indications for femoral intramedullary nailing were 120 acute fractures (7 pathological), 9 non-unions, 2 malunions and 19 fractures with delayed union previously operated by another method. Twenty two were polytrauma patients. Twenty one fractures were open (grade a and b). Various types of reamed long antegrade nails were used in 117 cases and a long g-nail in 33 cases.

Main complications were: shortening 10, heterotopic ossification 6, knee stiffness 8, fat embolism 2, deep venous thrombosis 4, pulmonary embolism 2, superficial wound infection 8, deep infection 1, lengthening 4, rotational deformity 10, nonunion 0, missed distal screw targeting 10, drill breakage 7, malposition of the nail 7, additional intraoperative fracture occurrence 7. In 60 cases the insertion of the guide was performed by a small incision at the fracture site. Mean union time was approximately 4 weeks shorter when a closed reduction was performed.

Technical complications in the majority of cases affected fractures that were operated after midnight. Elderly patients (> 65 years old), were most probably to be subjected a complication while less complications occurred in younger patients. A well prepared operating room and prevention of surgeons fatigue is needed to reduce complications.

Purpose: The results of infected total knee arthroplasty management are studied, in order to evaluate the effectiveness of our treatment protocol, which is based on clinical manifestations of the infection.

Material: 22 infected total knee arthoplasty were studied (9 of them had been send from other hospitals).

Method: According to the clinical manifestations of the infection, patients were treated with one of the following methods: In the first group, 7 patients with primary postoperative infection (within the first 3 weeks after the operation) and with no MRSA pathogen, were treated with surgical debridement, keeping off the wound drainage for a long period and with antibiotic administration for 6–12 weeks. In the second group, 10 patients with late onset of infection or primary infection with MRSA pathogen or acute hematogenic infection with loose implant, were treated with wide surgical debridment, removal of all the materials and revision surgery after a 2–3 months period of antibiotic administration. In the third group, 3 patients with acute hematogenic infection but stable implants 2 to 6 years postoperatively, were treated with meticulous surgical debridement, exchange of polyethylene and administration of antibiotics for a long period. In the fourth group, 2 very old patients with bad general condition, were treated only with antibiotics.

Results: In the first group there is full eradication of the infection and there is no indication of recurrence (F.U 2–6 years). In the second group 8 patients had their infection fully eradicated and 2 patients recurrended 6 and 8 months postoperatively. One underwent arthrodesis and the other is still receiving antibiotics under pathologist directions. In both patients there was a great amount of bone absorption and soft tissue necrosis around the implant. For patients of the third group complete eradication was achieved. Finally, for the 2 patients of the forth group, periods of exacerbation and remission of the infection exist, with good and poor quality of life, respectively.

Conclusions: The treatment protocol that we apply was based on the clinical manifestations of the infection and was successful in most cases. Bone absorption, tissue necrosis and microorganism resistance are bad prognostic factors.
