Background: We presents the axial and via perforator vascularised flaps for covering lower limb posttraumatic, septic and diabetic necrosis.

Methods and patients: During the past 4 years we operated 23 patients, 20 males and 3 females with posttraumatic or septic lower limb necrosis: two of the external maleolar area, 6 of the dorsal foot, three of the Achilles tendon area, 2 anterior lower tibia, 4 of the calcaneal area. Osteomyelitis was present in 6 cases (tibia, metatarsals, calcaneus)

All traumatic cases happened almost 2 weeks before operation except three which caused between 2 and 6 months earlier. In the 2 diabetic cases the lesion appeared between 3 and 5 month ago.

We have performed: 9 sural flaps, 5 perforator-posterior tibial artery flap, 1 medial plantar, 4 based on distal perforators of the peroneal artery, 1 Saphenous, 2 muscular flaps.

All patients were between 17 and 81 years all and the follow up between 8 month and 2 years. Everywhere before the flap we performed surgical debridement.

As supplementary combined reconstructive technique we performed: 1. Mega papineau technique, 2. Bone filling, 3. Distraction osteogennesis, with spatial Taylor frame.

Results: We covered successfully the defects, with satisfactory aesthetical results, while the functional ability was not compromised.

Results: The above flaps have been proved effective for covering the lower limb defects.

These flaps are better tolerated by the patient than the traditional techniques and safer, less demanding and faster to perform than the free tissue transfers.

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.

Aim: To evaluate the results of management of Char-cot foot and ankle deformities by the use of the Ilizarov apparatus.

Material-Method: This is a retrospective study of 11 cases (9 patients) aged from 39 to 60 years old (mean 44 years), all suffering from Charcot foot neuroarthropathy. All cases showed established midfoot breakdown. In four cases hindfoot deformity coexisted. Three feet were ulcerated. In six cases the Iizarov frame was applied using complex hinges and closed compression fusions were performed, utilizing the bent wire technique. In five cases the correction of the deformities was performed acutely with the use of percutaneous cannulated screws. In the later cases the Ilizarov frame neutralized the former osteosynthesis method. The Ilizarov device remained attached for 8 weeks, regardless the presence of other osteosynthesis hardware. The Maryland Foot score (MFS) was utilized for objective assessment by the physician and the SF-36 questionaire for subjective assessment by the patient.

Results: A statistically significant improvement in MFS and SF-36 score was recorded. In all cases the aim for a stable and painless extremity was achieved. All patients returned to their previous activities and kept using normal shoe wear.

Conclusions: A lot of references are found in the literature describing failure in the treatment of Charcot foot deformity with the use of internal fixation. This is justified by the poor bone quality and decreased bone density of the diabetic and alcoholic patients. The use of tensioned wires in multiple levels provides adequate fixation in cases where a frame is used solely and safe neutralization where a frame is combined with internal fixation.

There are a few reports in the literature that compare the results of medial and lateral meniscectomy, especially in older patients.

Eighty three patients that underwent partial menis-cectomy were studied (45 men, 38 women), all older than 45 years. Forty eight cases considered medial and 35 cases lateral meniscectomy, mainly of the posterior horn. According to Outbridge and French Arthroscopic system criteria, there was not significant difference for the osteoarthritic changes that were found arthroscopically. 48% of the patients had no arthritic damage. Radiological evaluation of the results was done with Fairbank classification and International Knee Documentation Committee criteria, pre and postoperatively. Preoperatively, 50% of the patients had no pathologic radiological findings and postoperatively, both groups had similar radiological results. Tapper – Hoover criteria and Lysholm II Score were used for the evaluation of clinical results. 83% of medial and 78% of lateral meniscus tear’s repair had satisfactory clinical results and no statistical significance was documented in our series, despite reports from the literature of poorer clinical results for lateral meniscectomy. In both groups, clinical results were not influenced by the severity of cartilage lesions or by the age of patients, but by the amount of meniscus removal and the delay of arthroscopy, greater than 2 months.

A significant number of hallux valgus is associated with valgus deviation of 2nd, 3rd and 4th toes. We recommend correction of the valgus deformity of all four rays simultaneously., because recurrence of the hallux valgus is very frequent if only the first ray is realigned.

From 1978 to 1990 a series of 236 feet were operated upon for hallux valgus deformity using a distal osteotomy of the first rnetatarsal. These cases were followed up for a mean of 6, 1 years and showed that the recurrence rate was as high as 28%. Our observation was that, in the majority’ of cases, recurrence of the deformity occurred in those feet in which hallux valgus was combined with valgus deformity of the lesser toes due to varus deviation of the corresponded metatarsals. From 1990 to 1998, another series of 386 feet were operated for hallux valgus. In more than one third of them (142 feet in 96 patients) hallux valgus was associated by valgus deformity of the 2nd, 3rd, and 4th toes. These cases were operated using a distal osteotomy of the first rnetatarsal combined with osteotomies of lesser metatarsals aiming not only to face metatarsalgia, but to correct valgus deformity of the lesser toes simultaneously. These patients were followed up for a mean of 4.8 years.

The results were excellent in 73 feet, good in 47, fair in 17 and poor in 5. The recurrence rate dropped to 7%.

If hallux valgus is combined with valgus deformity of the lesser toes, correction of only the first ray creates a gap between first and second toe. Consequently there is no blocking effect toward valgus deviation of the great toe due to the gap remaining between the first and second toe.

The above combined procedure seems to give better results with low recurrence rate in comparison with the results of single correction of the first ray.

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.

In this paper the results of correction of bone deformities using the llizarov methods, are presented.

Fifty-nine patients, 42 with malunion and 17 with mal-nonunion of tibia or femur were operated upon using the llizarov circular fixator. Another 28 cases were corrected using a unilateral device. There were: a) 30 angular deformities, 18 of which were combined with shortening, b) 21 angular deformities associated with translation and c) 36 complex, deformities including angulation, translation, shortening and malrotation.

Two rings above and two below the apex of the deformity were always required. Different types of hinges were used between them, depending on the type of the deformity. The corticotomy was performed at the apex of the deformity for the majority of the cases. In 18 patients with hypovascular and eburnated bone, or bone covered with soft tissue of poor quality, the corticotomy was done more proximal or more distal to the apex of the deformity. In complex deformities the correction sequence was: 1) correction of angulation and shortening simultaneously, 2) correction of rotation, 3) and finally correction of translation. The true plane of the deformity and the plane of placement of the hinges were determined by a computerized formula that we developed.

The deformities were corrected in all cases in which the hinges were placed at the correct position but in 5 cases we had to re-orient the hinges in order to achieve the correction. The corticotomy or pseudarthrosis consolidated in all cases. Residual leg length discrepancy remained in three patients, not exceeding 135 cm. Great care was taken to prevent complications during operation as well as during the post operative period. However, there were numerous obstacles, problems and true complications. All these were managed aggressively as soon as they appeared. The final results were very satisfactory.

We conclude that the revolutionary llizarov methods can solve bone deformity problems that cannot be faced by the traditional methods. It is critically important to place the hinges at the correct position in order to achieve the desired correction. Our computer program definitely helps to this purpose. The surgeon must always be vigilant in order to prevent complications and to deal with them immediately.
