Salvage of complicated diaphyseal femoral fractures by 1-stage open debridement and Ilizarov technique.

Infected femoral shaft fractures and femoral nonunions are difficult to manage. In the presence of associated segmental bony defects, limb length discrepancy, or complex deformities, Ilizarov techniques seem to be the ideal choice for management. We would like to describe small case series of 3 patients managed using Ilizarov techniques: the first patient with infected nonunion of a femoral shaft fracture over an interlocking nail, the second patient with infected femoral shaft plating, and the third with longstanding femoral shaft hypertrophic nonunion who had multiple surgeries and presented at the end with a broken intramedullary nail. The principal management in all cases was a single-stage aggressive debridement and fixation using circular Ilizarov external fixator or hybrid external fixator followed by either segmental bone transport for the first 2 patients or monofocal compression distraction for the third patient. The end result was clinical and radiological union in all patients with equalization of the limb length.

Functional outcomes of nonunion scaphoid fracture treated by pronator quadratus pedicled bone graft.

Between 1998 and 2007, a pronator quadratus pedicled bone graft was performed for 45 patients of ununited scaphoid fracture. One of them had bilateral ununited scaphoid fracture. There were 29 men and 16 women with a median age at operation of 24 (16-32) years. The affected side was the right side (dominant hand) in 32 patients whereas 13 patients had fracture of the nondominant left side. There had been 32 proximal pseudoarthrosis (through or proximal to the junction of the proximal and middle thirds of the bone) and 14 of the middle third of the scaphoid. The original fractures were caused by motor cycle accidents in 23 patients, falling on outstretched hand in 15 patients, and sport injuries in the remaining 7 patients. Surgery was indicated from 5 months to 6 years after injury (average 43 months) because of complaints of pain on heavy work. The fracture has been missed at the initial examination in 23 patients whereas cast immobilization was done for 6 weeks and 3 months in 15 and 7 cases, respectively, that had failed to result in union. There were no preoperative osteoarthritic changes, but in 25 cases, there were avascular necrosis of the proximal fragment of the scaphoid. Forty-three patients showed radiographic union after an average of 14 weeks (12-16 weeks). One patient had dislodgement of the graft and refused to do it again. The average range of movement of wrist improved after operation. Taken as a percentage of the normal range, dorsiflexion increased from 69% to 80%, palmar flexion from 66% to 76%, radial deviation from 45% to 70%, and ulnar deviation from 67% to 84%. Grip strength improved from 82% to 92% of normal. All the patients have been able to return to their former activities with no pain.

Ilizarov gradual correction of genu varum deformity in adults.

Valgus producing high tibial osteotomy (HTO) is an effective treatment option for medial compartment osteoarthrosis with varus deformity in young patients. The most common complications of conventional high tibial osteotomy techniques are related to accuracy of correction. Major angle correction of more than 15 degrees with an osteotomy proximal to the tibial tuberosity may cause significant change in patellofemoral mechanics and patellar height. Valgus HTO was performed in 11 lower limbs of 9 patients with gradual correction of the varus deformity using an Ilizarov external fixator, with the osteotomy at the distal border of the tibial tuberosity. The mean age of the patients was 38.5 years. The average correction was 17 degrees. They were followed up for an average of 25 months. The mean preoperative "Hospital for Special Surgery" (HSS) score was 68 and improved to a mean of 90 at follow-up. Nine limbs had excellent or good HSS scores. Disadvantages of this technique were mainly pin tract infection and poor patient acceptance and noncompliance.

Early surgical exploration of radial nerve injury associated with fracture shaft humerus.

The series included 36 patients, predominantly male, mean age 30.3 years. The most common cause of injury was motor car accident in 20 patients. Postreduction radial nerve injury occurred in nine cases. Open fracture humerus with radial nerve injury in seven cases. The fractures were situated in the middle or distal third of the humeral shaft. Most were transverse fractures. Twelve patients had surgery on the day of injury and the other 24 at a mean of 8 days later (3-14). Narrow dynamic compression plate was generally used for fixation. Exploration of the radial nerve demonstrated compression at the lateral intermuscular septum in 19 cases, entrapment in the fracture site in nine cases, and loss of its continuity in eight cases. Neurolysis was required in 20 cases, epineurorrhaphy in nine cases, interfascicular nerve grafts in five, and first-intention tendon transfer in two. Results of nerve surgery were assessed with the MRC (Medical Research Council) at a mean follow-up of 8.2 years. Outcome was rated good to excellent in 28 patients, fair in 1, and poor (failure) in 3. First-intention tendon transfers were performed in 2 patients and 2 patients were lost to follow-up. Mean delay to recovery was 7 months after neurolysis and nerve repair and 15 months after nerve grafts. The fracture was united in all cases. The mean time of union was 5 months.

Management of traumatic tibial defects using free vascularized fibula or Ilizarov bone transport: a comparative study.

There are several options for the treatment of traumatic tibial defects. Among these options, free vascularized fibula and Ilizarov bone transport are well-known and effective techniques. The differences between both techniques and the indications for each of them are not well studied in the literature. Between September 1995 and December 2004, Ilizarov bone transport and free vascularized fibula were used to treat 25 traumatic bone. Patients were divided into two groups, Ilizarov group (12) and free fibula group (13). Preoperative data, operative data, duration of treatment, functional outcome, range of motion loss, number of secondary procedures, and type and rate of complications were compared in both groups. All the cases were ultimately united in both groups. Operative time and blood loss were significantly higher in the free fibula group. Although external fixation time was longer in the Ilizarov group, the overall duration of treatment was similar. Range of motion loss was less in the Ilizarov group, but the overall functional outcome was similar. There was no difference in complication rate, or number secondary procedures. Defect size was found to have the most significant effect on the results. Results were much better in the free fibula group when the defect length was 12 cm or more while the results were better in Ilizarov group when the defect length was less than 12 cm. We recommend using free vascularized fibula for traumatic tibial defects of 12 cm or more, whenever experience is available.

Oberlin's ulnar nerve transfer to the biceps motor nerve in obstetric brachial plexus palsy: indications, and good and bad results.

We present 7 children with obstetric brachial plexus palsy treated by transferring two motor fascicles out of the ulnar nerve to the biceps nerve. Three were male, and 4 were female. The left-side brachial plexus was affected in 4 patients, and the right side in 3 patients. All children had vaginal delivery; two of them presented with shoulder dystocia. The average birth weight was 4300 g (range, 3620-5500 g). Average age at time of operation was 16 months (range, 11-24 months). The indication for the operation was absent active elbow flexion with active shoulder abduction against gravity in 4 cases, and no biceps function and bad shoulder function in 3 cases. Oberlin's ulnar nerve transfer was done in 4 cases without brachial plexus exploration in those children with good shoulder function, and exploration of the brachial plexus was performed in the other 3 cases with bad shoulder function. The average follow-up was 19 months (range, 13-30 months). Five children had biceps muscle >or=M(3) with active elbow flexion against gravity, and 2 children had biceps muscle

Repeated upper limb salvage in a case of severe traumatic soft-tissue and brachial artery defect.

We present the case of a 9-year-old male patient who suffered a gunshot injury to the right arm. The patient arrived in shock, his right arm severely traumatized, with soft-tissue loss involving the anterior surface and both sides of the right arm. The humerus was exposed. There was brachial artery defect and damage to the lateral fibers of the median nerve. The mangled extremity severity score (MESS) was 8 points. The patient was treated with general resuscitation, blood transfusion, and debridement. A venous graft, 12 cm in length, to bridge the brachial artery defect, and tendon transfer, triceps to the biceps, was performed in one step. Postoperatively, there was a normal radial pulse, normal skin color, normal temperature, and normal movement of the fingers without pain. Unfortunately, the patient then sustained a second trauma to the right arm 3 weeks later, rupturing the graft. This time he lost 1,500 cc of blood. After another blood transfusion, we performed a second reverse saphenous vein graft. The patient stayed at the hospital for 3 weeks. At follow-up 12 months later, the limb has good function and, except for the presence of a scar and skin graft, is equal in appearance to the left side.
