Is Venous Thromboembolism Prophylaxis Needed in Patients Undergoing Knee Arthroscopy? A Prospective Observational Study.

BACKGROUND: Although rare, deep vein thrombosis is a potentially life-threatening complication of knee arthroscopy. There are scanty literature analysing deep vein thrombosis after arthroscopy in Nepal. This study aimed to identify the prevalence of deep vein thrombosis in patients undergoing knee arthroscopy without chemoprophylaxis postoperatively at 2 weeks and 6 weeks, respectively. The study also aimed to estimate the risk of deep vein thrombosis in these patients by using Caprini Risk Assessment Model. METHODS: This prospective observational study was conducted at AKB center, B and B Hospital, Gwarko, Lalitpur, over a period of 16 months. All patients who underwent arthroscopy knee surgeries fulfilling the inclusion criteria were included in the study. The primary outcome measure was the prevalence of deep vein thrombosis as diagnosed by compression color-coded ultrasonography of the popliteal vein and calf vein at 2 weeks and 6 weeks postoperatively. The secondary outcome measure was the prevalence of deep vein thrombosis in the risk groups according to Caprini Risk Assessment Model. RESULTS: Out of 612 patients who underwent arthroscopic knee surgeries during the study period, 2 patients (0.33%) developed deep vein thrombosis at 6 weeks follow-up as diagnosed with ultrasonography of the popliteal and calf veins. The prevalence rate in high-risk group was 0.33% (1 in 307) and in very high-risk group was 5.88% (1 in 17). CONCLUSIONS: There was a low prevalence of deep vein thrombosis without chemoprophylaxis following knee arthroscopy in our study. There was higher prevalence of deep vein thrombosis in very high-risk group patients, so close monitoring of such patients during follow-up is recommended.

Implantless Supplementary Fixation of Anterior Cruciate Ligament in Tibia with "Make and Use" Anchor.

Supplementary fixation after anterior cruciate ligament reconstruction may be necessary in some situations. There are several methods described for supplementary fixation with their advantages and disadvantages. Anchor fixation is preferred by many because it does not require a second surgery for removal. However, anchors are costly. We described the "make and use" all-suture anchor, which can be made instantly whenever required. We modified "make and use" all-suture anchors for supplementary fixation after ACL reconstruction. This technical note aims to describe the method of supplementary fixation using the "make and use" all-suture anchor.

Morphometric Study of Sub Axial Cervical Spine Pedicles in Nepalese Population.

BACKGROUND: Mal-positioning of cervical screws risks neurovascular injury so, it is necessary to understand cervical pedicle morphology for pedicle screw fixation in the region. The risks of pedicle screw insertion in the cervical spine can be mitigated by a three-dimensional appreciation of pedicle anatomy. The study aims to determine the morphology of the sub axial cervical spine pedicles in Nepalese Population based on computerized tomography. METHODS: A cross-sectional study using computerized tomography scans of the spine was made among the randomly selected 87 patients who had visited National Trauma center, Kathmandu, Nepal with vertebral fracture other than cervical vertebrae. Patient was examined as per Advanced Trauma Life support protocol and neurological assessment. Measurement was done from the third cervical vertebra down to the seventh cervical vertebra in computer with standard software in the department of radiology from where all the computerized tomography scan reporting are done. RESULTS: The mean pedicle length ranged from 4.41 mm at C3 to 4.96 mm at C7 where mean pedicle height ranged from 4.64 at C3 to 5.12 at C7. Pedicle length, pedicle height and pedicle width were observed to be statistically significant with gender. The pedicle axial length of C3 and C7 vertebra were found significant with gender. All parameters were found to be greater in male compared to female. CONCLUSIONS: The study revealed that pedicle length, pedicle height, pedicle width, pedicle axial length increased from third to seventh cervical however, transverse angulation increased up to fifth vertebra and decreased to seventh vertebra.
