Objective To investigate the efficacy of double-plating fixation via U-shaped incision in the treatment of type C3.3 distal femoral fractures. Methods From July 2006 to February 2009, 11 cases of type C3.3 distal femoral fractures were treated, including 5 open fractures and 6 closed fractures. Among them, there were 7 males and 4 females with an averageage of 43 years (range, 27-55 years). The locations were left side in 6 cases and right side in 5 cases. Fracture was caused by traffic accident in 8 cases and fall ing from height in 3 cases. The time from injury to hospital ization was 30 minutes to 7 days. After bone traction for 3 to 8 days, the operations were performed by double-plating fixation via U-shaped incision, and autograft of il iac bone or allogeneic bone grafting. Results The average time of operation was 128 minutes (range, 105-150 minutes). The average blood loss during operation was 344 mL (range, 290-380 mL). Shallow local skin flap necrosis occurred in 2 cases, and incision healed by first intention in others patients. All patients were followed up 22 months on average (range, 12-36 months). The bone union was achieved within 3-6 months (4.4 months on average). No implant loosening or refracture was found. According to Merchan et al criteria for knee joint function evaluation, the results were excellent in 4 cases, good in 5 cases, fair in 1 case, and poor in 1 case at last follow-up; the excellent and good rate was 81.8%. Conclusion The double-plating fixation via U-shaped incision has the advantages of better exposure, great convenience to manipulation, anatomical reduction, and rigid fixation. It provides an effective treatment for type C3.3 distal femoral fracture. However, its operation indications and operating instructions should be strictly followed.
Objective To explore the effectiveness and advantages of using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair compared with traditional arthroscopic suture shuttle. Methods The clinical data of 41 patients with Bankart lesion, who met the selection criteria and were admitted between August 2019 and October 2021, was retrospectively analyzed. Under arthroscopy, the inferior capsulolabral complex was stitched with Fastpass Scorpion suture passer in 27 patients (FS group) and with arthroscopic suture shuttle in 14 patients (ASS group). There was no significant difference between the two groups (P>0.05) in gender, age, injured side, frequency of shoulder dislocation, time from first dislocation to operation, and preoperative Rowe score of shoulder. Taking successful suture and pull-tightening as the criteria for completion of repair, the number of patients that were repaired at 5∶00 to 6∶00 (<6:00) and 6∶00 to 7∶00 positions of the glenoid in the two groups was compared. The operation time, and the difference of Rowe shoulder score betwee pre- and post-operation, the occurrence of shoulder joint dislocation, the results of apprehension test, and the constituent ratio of recovery to the pre-injury movement level between the two groups at 1 year after operation. Results Both groups completed the repair at 5∶00 to 6∶00 (<6∶00), and the constituent ratio of patients completed at 6∶00 to 7∶00 was significantly greater in the FS group than in the ASS group (P<0.05). The operation time was significantly shorter in the FS group than in the ASS group (P<0.05). All incisions in the two groups healed by first intention. All patients were followed up 12-36 months (mean, 19.1 months). No anchor displacement or neurovascular injury occurred during follow-up. Rowe score of shoulder in the two groups significantly improved at 1 year after operation than preoperative scores (P<0.05), and there was no significant difference in the difference of Rowe shoulder score between pre- and post-operation between the two groups (P>0.05). At 1 year after operation, no re-dislocation occurred, and there was no significant difference in the apprehension test and the constituent ratio of recovery to the pre-injury movement level between the two groups (P>0.05). Conclusion Compared with the arthroscopic suture shuttle, using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair is more convenient, saves operation time, and has good effectiveness.
