Arthroscopic screw fixation of large anterior glenoid fractures

Ten patients after traumatic shoulder dislocation with resulting instability due to an acute anterior glenoid fracture involving at least 21 percent of the glenoid length were treated by arthroscopic screw fixation of the fragment. The average fragment size measured 26.2% of the glenoid length. Pre- and postoperative radiographic evaluations were performed with three-dimensional CT scans. A cannulated titanium screw system was used for fragment fixation. All ten patients were followed up radiographically and, by evaluation of the Rowe score, clinically after a minimum of 2 years. At follow-up the Rowe score averaged 94 points. According to the rating scale, seven patients had an excellent result, two patients a good result, and one, fair result. In all patients CT scan confirmed that the fracture had healed in an anatomical position. One patient had one episode of traumatic redislocation with a positive apprehension test at follow up. In one case, removal of the screw was necessary due to mechanical impingement. We recommend this arthroscopic technique allowing for closed reduction and internal screw fixation of large anterior glenoid fractures, ensuring anatomical fracture healing and gleno-humeral joint stability.

Fixation of chondral fracture of the weight-bearing area of the lateral femoral condyle in an adolescent

Purely chondral fractures of the distal femur associated with patellar dislocation are uncommon, and treatment varies from fixation to debridement and marrow stimulation techniques. The unusual case reported here involves an adolescent who underwent fixation of a purely chondral fracture involving a large weight-bearing portion of the lateral femoral condyle. Chondral fracture healing was confirmed on follow-up magnetic resonance imaging and arthroscopic examination. This case suggests that fixation of purely chondral fractures can be successful in weight-bearing areas of the knee. Level of evidence V.

Arthroscopic treatment of a talar neck fracture: a case report

Talar neck fractures are severe injuries, and their complications can lead to significant functional disability. Open reduction and internal fixation still constitute the treatment of choice. We report a case of a patient with a Hawkins type III talar neck fracture who was treated successfully with the use of an entirely arthroscopic technique. Four arthroscopic portals were used to control fracture reduction and fixation, which was made by two cannulated screws. There were no complications, and the patient returned uneventfully to her previous daily activities. LEVEL OF EVIDENCE: Therapeutic study, Case report with no comparison group, Level IV.

Arthroscopic reduction and internal fixation (ARIF) of lateral tibial plateau fractures

Arthroscopic reduction and internal fixation of tibial plateau fractures has been well documented over the last 15 years. Better visualization, less traumatic surgery, reconstruction of accompanying injuries and early mobilization have encouraged arthroscopic surgeons to use this technique more widely. With experience, surgeons became more comfortable in using arthroscopy-assisted surgery not only in split fractures of the lateral tibial plateau (41-B1) but also in more complex tibial and femoral fractures. In this study, 31 patients with intra-articular fractures of the lateral tibial plateau were operated on between 1991 and 1996. The fractures were classified as follows: x12 AO-type B1, x7 B2, x10 B3, x2 C3. Diagnostic arthroscopy and repair of soft tissue injuries was followed by arthroscopic reduction in all patients and supplemented with internal fixation in 29 patients. Postoperatively, an aggressive physical therapy regimen was performed with immediate mobilization and early partial weight bearing. All patients were examined for follow-up after 15-32 months (mean 25.1). In all cases the fractures were stable and allowed full weight-bearing. At follow-up, 25 patients had anatomic reduction. Anatomical reduction cannot be restored in all cases of open reconstruction because of cartilage defects. Fracture reduction using arthroscopic techniques is a suitable alternative for joint fracture repair because additional soft tissue damage can be minimized.     

CT- and fluoroscopy-guided percutaneous screw fixation of a “carrot-stick” spinal fracture in an elderly man with ankylosing spondylitis

We present a case of percutaneous fixation of a “carrot-stick” spinal fracture in an elderly patient with ankylosing spondylitis (AS). A surgical stabilization was not possible in this 83-year-old man with comorbidities. Under local anesthesia, percutaneous screw fixation of a transdiscal shear fracture at the level T10-T11 was performed using computed tomography (CT) and fluoroscopy guidance. Two 4.0-mm Asnis III cannulated screws were placed to fix facet joints using transfacet pedicle pathway. The procedure time was 30 min. Using the visual analog scale (VAS), pain decreased from 10, preoperatively, to 1 after the procedure. Radiographic fusion was observed at a 3-month post-procedural CT scan. CT- and fluoroscopy-guided percutaneous screw fixation of spinal fractures could potentially be an alternative to surgery in elderly AS patients with poor performance status.

Pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture

A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported. The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair. There was a good functional result following minimally invasive pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture. There are no previous reports of similar pseudo-arthrosis repairs, and other authors report good results of delayed refixation of PCL avulsion fractures. Therefore, refixation and pseudo-arthrosis repair should be considered as a viable treatment.     

Arthroscopic treatment of a juvenile tillaux fracture

Tillaux fractures are relatively uncommon fractures of the anterolateral tibial epiphysis that are observed in adolescents during the 18-month period when the distal tibial physis has begun to fuse centrally. The case of a 16-year-old boy with a juvenile Tillaux fracture treated successfully by reduction and percutaneous fixation under arthroscopic control is presented. The procedure is technically feasible, allows accurate reconstruction of the weight bearing surface of the joint and secure internal fixation of the fracture. The authors describe the principles of the procedure and discuss its advantages compared to open surgery.
