Arthroscopic pinning of osteochondritis dissecans of the knee

Nine cases with osteochondritis dissecans were treated by arthroscopic pinning using K-wires. The average age of the patients was 18.5 years. These cases were followed up clinically and radiologically for an average period of 14 months. The results of this surgery were satisfactory with no significant complications and the patients were able to resume their normal activities within a reasonable period of time

use of calcium phosphate bone substitute in the treatment of unicameral bone cysts of the humerus

There are several modalities for treatment of unicameral bone cyst. One of these modalities is the use of calcium phosphate as a bone substitute to fill the cyst after curettage. Thirteen cases of simple bone cysts of the upper humerus were treated by this method. The patients were followed up for 1 to 4 years. The success rate was 92.3%. These results were compared with other studies using autogenous bone graft or intralesional injection of prednisolone

Posterior wall acetabular fractures clinical outcome of surgical treatment

Fifteen patients with postterior wall acetabular fractures were treated surgically. All the fractures resulted from high energy traum a, most with associated injuries. Forteen of these patients were followed up to at least 9 months, only one was lost for follow up. Clinical outcome was analyzedd according to Harris hip score and also radiografically. In 78.4% of the patients the surgical procedure was judged successful [Harris hip score 80 points or more]. Injury of the femoral head lead to bad clinical outcome though no significant statistical correlation was possible because we had this injury just once in our series and because this case had another complication as well [Avascular necrosis of the head of femur]. Quality of reduction was found to influence the clinical outcome with positive statistical correlation. Open reduction and internal fixation of displaced posterior wall acetabular fractures though surgically demanding procedure can give very good result when patients are managed properly through experienced and organized team with clear and stable system of management

Evaluation of transpedicular fixation in treating dorso-lumbar injuries

From April 1996 through July 1999, we encountered 27 patients with dorso-lumbar injuries of the spine and were treated by transpedicular rod fixation systems. 17 patients had burst fractures, and 10 patients had fracture-dislocations. Posterolateral fusion was done to all patients. 5 patients had complete paraplegia, 15 patients had various neurological deficits, and 7 patients were neurologically free before surgery. Indirect decompression was done for the patients who have canal compromise less than 50%. The average follow-up period was 18 months [range 6-30 months]. The average correction of the anterior wedge compression angle postoperatively was 11.5° with an average loss of 3.1° at follow-up. The average correction of the local kyphosis angle was 12.2° with an average loss 4.2° at follow-up
