Aim of the study: The evaluation of denervation efficiency in the treatment of the arthritis of the base of the thumb.

Material and method. Between 2001– 2004, 15 patients were surgically treated for arthritis of the basis of the thumb. There were all females of an average age of 53 years. In all patients the procedure was done ambulatory under local anesthesia. After completing a protocol form, regarding pain motion and power of the thumb, an incision was made at the level of the wrist crease extended from the level of FCR to the level of the 2nd extensor compartment. Through this incision the articular branches which conform the studies of Wilhem and Fusche supply the 1st CMC joint were divided.

A supplementary incision for the first intermetacarpal space was made. The patients were free to return to their activities the third postoperative day and they were reviewed after 3, 6, 12, 24 months by an independent doctor. Their data were also recorded conform the protocol

Results: Twelve patients out of 15 had excellent improvement of their strength. Pinch and grip power was doubled. Mobility of the thumb according to Kapanji scale was improved in all cases. Pain was reduced in 65% average. The patients were satisfied from the operation. There was one patient with poor improvement and two patients who never shown up at the follow-up. As the last were at the beginning of our learning curve we think that could have a less satisfactory result.

Discussion: The method is simple with minimal impact to the patient activity or life. It gives good results in 65% –75% and leaves further operative procedures possible. Although there not enough data yet for this procedure and our number of cases is small with short follow-up we believe that it is a nice procedure, it satisfies both the patient and the surgeon regarding the overall improvement of mobility and pain.

Purpose: End results analysis of surgical treatment of posttraumatic bone defects in the lower extremity by Ilizarov method and intramedullary nailing augmentation during consolidation.

Materials and method: Between 1990–2000,83 patients with posttraumatic bone defect (femur 26, tibia 57) with an average age of 38 years (11–65y.) were surgically treated. Open fracture was the cause of bone defect in 50 patients (60%). In the rest 33 (40%) patients, the bone defect was the result of a surgical removal of a nonviable bone due to osteomyelitis or infected non-union. The average length of bone defect was 8,5 cm. (4–20 cm.). In all cases corticotomy and application of Ilizarov device was necessary to initiate bone transport. In 26 patients the Ilizarov device was removed during consolidation and interlocking intramedullary nailing was performed. Selection criteria for changing method were: 1) delayed union at the docking site (13 pt.), 2) Intolerance of the Ilizarov device (6 pt.), 3) Angular deformity > 10 degrees (7 pt.). Radiological and clinical assessment was performed periodically. Functional recovery and bone healing were evaluated according to A.S.A.M.I criteria.

Results: Forty-eight patients (58%) presented delayed union at the docking site. In 35 patients compression- distraction was necessary to promote union. The rest 13 patients were healed using an interlocking intramedullary nailing. Three refractures needed reapplication of the Ilizarov device. Angular deformity of more than 10 degrees was found in 13 patients. Seven of them needed an osteotomy and intramedullary nailing. All bone defects were finally covered and solid bone formation resulted.

Conclusions: The Ilizarov method offers unique advantages in treatment of bone defects. The use of an interlocking intramedullary nail during consolidation, is a treatment option for delayed docking site union and prolonged treatment time.

Purpose: A clinical retrospective study of surgical treatment of chronic posttraumatic osteomyelitis by the Ilizarov method was conducted by analyzing the end results.The aim was to evaluate the efficacy of distraction osteogenesis in covering large bone defects and eradicate infection.

Materials and method: Between 1990–2000, twenty-one patients with chronic osteomyelitis were surgically treated. Inclusion criteria were: 1) active infection of more than six months and 2) bone defect (after the surgical debridement was completed) > 4cm.The average length of bone defect was 9,5 cm. (4–28cm.). In all cases corticotomy and application of the Ilizarov device was necessary to initiate bone transport.The protocol of the Association for the Study and Application of the Method of Ilizarov (A.S.A.M.I), was used to evaluate the results. All patients were examined clinically and radiographically in order to assess the proper alignment, the progress of bone healing and possible signs of infection.

Result: Thirteen patients (62%) presented delayed union at the docking site. In 4 patients compression –distraction was necessary to promote union. In 9 patients (43%) the Ilizarov device was removed and interlocked intramedullary nailing was performed after eradication of the infection was confirmed by clinical and laboratory data. Recurrence of infection occurred in one patient. Elimination of infection and solid bone formation was the end result for all patients. Two refractures at the docking site needed reapplication of an Ilizarov device. In one case angular deformity of more than 10 degrees needed correctional osteotomy.

Conclusions: The Ilizarov method addresses successfully infection, bone defect, deformity, and leg length discrepancy simultaneously. All these may coexist in difficult cases of chronic osteomyelitis. Complications associated specifically with bone transport in exceeded bone defects ,after radical resection of infected bone, include certainly delayed union or non-union at the docking site and prolonged treatment time.

Purpose: The retrospective evaluation of long-term results after reconstructive radial osteotomy for mal-united distal radius fractures.

Material-Method: Twenty-eight patients (21 male and 7 female, average aged 46 years) with 23 dorsal and 5 palmar angulated malunited distal radius fractures were operatively treated during 1994–2002 in our department. The main indications were pain and functional impairment. Dorsal or palmar approach was used in proportion to the site of angulation. The preoperative average radial inclination, radial length and volar or dorsal tilt were 13.5 degrees, 6.3 mm and 23.5 degrees respectively. An open wedge radial osteotomy followed by interposition of trapezoidal iliac crest bone graft and fixation with plate ands crews was performed in all patients four months at least after the initial surgery. An ulnar leveling procedure was considered necessary in 2 patients.

Results: All patients were available in the last follow up evaluation (mean 3.7 years). The functional result according to Mayo wrist score was rated as very good in 15 patients, good in 7 and poor in 6. The average improvement in radial inclination was 14 degrees, in radial length 6.5 mm and in volar or dorsal tilt 21 degrees. The complication rate was 22.7%, including 2 material failures, 1 extensor pollicis longus rupture, 1 nonunion and 3 recurrences of the deformity.

Conclusion: Surgical reconstruction for malunion is technically demanding and may not completely restore the anatomy. Patient satisfaction, however, in terms of increased function, decreased pain and decreased deformity is sufficient high to warrant reconstructive treatment.

Aim: End result study of closed intramedullary nailing of humerus fractures.

Materials & methods: Between 1995–2003, 42 patients with fracture of the humeral shaft, were selected to be treated by I.N. The average age was 48 years old (17years–82years) The Selection criteria were: α) loss of closed reduction (24 patients), b) pathological fractures (5 patients), c) non-union following external fixation (2 patients) and d) delay of union (7 patients). The intramedullary nail was inserted through a proximal entry point via a transdeltoid incision. In 25 cases the entry point was below the greater tuberosity to avoid rotator cuff injury and in 18 cases the entry point was intraarticular. All nails were locked either proximal (41) or distally (1). Open technique was required for 21 cases. Passive full range of motion of elbow and shoulder joint was encouraged after the second postoperative day. Active assisted exercises were initiated the second postoperative week. Bone healing was confirmed by clinical and radiological findings. Shoulder mobility was evaluated by the Constant-Murley scoring system.

Results: The average follow-up time was 21 months (9 months–8 years).All fractures were finally healed. The average healing time was 13 weeks (8weeks–13weeks). Patients with extraarticular entry point of the nail had full passive shoulder motion between the 2th and the 4th postoperative week, whereas patients with intraarticular nail application presented delayed passive shoulder motion with final limitation of the normal range of motion. Seven patients had painful shoulder motion 3 months postoperatively. There were 4 patients with neurapraxia of the radial nerve installed posttraumatic, who had full recovery 3 months later. There was one proximal migrated nail, which required revision. None of the patients required nail removal.

Conclusions: Intramedullary nailing of humeral shaft fractures seems to be a reliable method of treatment. Shoulder mobilization after anterograde insertion of the nail can be easily restored with proper choice of entry point and proper physiotherapy program. The advantages of this method include: shorter operative time, less blood loss, small incision with minimal soft tissue damage. Extraarticular nail insertion should be the entry point of choice as there is no trauma to the rotator cuff.

Aims: To evaluate the effectiveness of the Ilizarov method in treating septic nonunions of lower extremities. Method: Between 1990–2001, 74 patients (59 males and 15 females), with infected nonunion of the tibia and femur were treated using the Ilizarov device (the monofocal or bifocal com-pressiondistraction technique). The average age was 36 years (range 17–68 years) and the patients were evaluated using a modiþed Paley classiþcation for septic nonunions. The mean preoperative bone defect was 9 cm (range 3–18 cm) and it was present in 39 of 74 patients. The mean lengthening index was 36 days/cm (range 27–42 days/cm), the mean external þxation time was 6,3 months (range 3–24 months) and the mean follow up period after frame removal was 4 years (range 1–11 years). Results: Bone union was achieved in all 74 patients (100%) with no infection recurrence. The bone results were excellent in 52 patients (70%), good in 11 (15%), fair in 6 (8%) and poor in 5 (7%), whereas the functional results were excellent in 27 patients (36,5%), good in 35 (47%), fair in 7 (9,5%) and poor in 5 (7%). In four patients bone grafting at the docking site was needed. Late complications included: 9 axial deformities (12,2%), 2 re-fractures (2,7%) and 28 patients (37,8%) with joint stiffness. Conclusions: The Ilizarov technique in the treatment of septic nonunion has a high rate of success considering bone union, bone loss restoration and eradication of infection Sports Ð varia

Aim of the study

End results analysis of operative treatment in transcaphoid perilunate dislocations.

Material and method

From 1/1/91 to 1/1/01 twenty transcaphoid perilunate dislocations were operative treated. Ligamentous lesions were repaired through a dorsal approach, either by directly suturing the ligaments (10cases), or by using mini Mitek anchors (8 cases). Simple approximation and stabilization with K-wires was performed in 2cases. Scaphoid fractures were treated by open reduction and internal osteosynthesis with Herbert screw (12 cases), cortical AO 2.0 screw (2cases) or K-wires (6 cases). The wrist remained immobilized in a slight flexed position with short arm plaster for 8 weeks. Physiotherapy was necessary for all patients to regain full range of motion. Clinical and radiological evaluation was possible for all patients. The end results were estimated according to Cooney’s evaluation system. Kinematics of the injured wrists was also tested by cineradiography in order to estimate the dynamic behaviour of the wrist. The Average follow-up time was 52 months (range 11–76).

Results

Twelve patients had excellent result, 4 good, 1 fair, and 3 poor. Fourteen out of 16 cases returned to their previous work. Additional operations were required in two patients: 1) four corner arthrodesis because of aseptic necrosis of the proximal pole of the scaphoid with arthritic changes, 2) Scaphoid reoperation because of non-union by Matti-Russe procedure. The later was found in cineradiography to present a painless rotational instability.

Conclusions

Transcaphoid perilunate dislocation has a very good response to early operative treatment. Dorsal ligament repair with mite mini anchors seems to be a reliable easy made method. Scaphoid fracture stabilization requires a stable compressive fixation. Herbert screw is ideal and can be safely placed from proximal to distal via the dorsal incision. Cineradiography is the best way to evaluate normal wrist kinematics.
