  • Effectiveness of three-needle and two-cable structure in treatment of inferior patellar pole avulsion fractures

    Objective To investigate the effectiveness of three-needle and two-cable structure in the treatment of inferior patellar pole avulsion fractures. Methods A clinical data of 62 patients with inferior patellar pole avulsion fractures who were admitted between January 2023 and December 2023 and met the selection criteria was retrospectively analyzed. Among them, the fractures were fixed with three-needle and two-cable structure in 32 patients (observation group) and traditional steel wire tension band in 30 cases (control group). There was no significant difference in the baseline data of age, gender, side of the affected limb, cause of injury, and disease duration between the two groups (P>0.05). The operation time, fracture healing and healing time, patellar height (Insall-Salvati index), occurrence of complications, knee range of motion, and Böstman score at last follow-up were compared between the two groups. Results The operation time of the observation group was significantly shorter than that of the control group (P<0.05). Patients in both groups were followed up 6-12 months (mean, 10.4 months). X-ray films re-examination showed that all fractures healed, and the fracture healing time was significantly shorter in observation group than in control group (P<0.05); no significant difference was found in Insall-Salvati index between the two groups (P>0.05). During follow-up, the complications occurred in 2 cases (6.25%) of observation group and in 9 cases (30.00%) of control group, and the difference in the incidences between the two groups was significant (P<0.05). At last follow-up, the range of motion and Böstman score of the knee joint in observation group were significantly superior to control group (P<0.05). Conclusion Compared with the traditional steel wire tension band fixation, the three-needle and two-cable structure fixation of the inferior patellar pole avulsion fractures is firm, which allows the knee joint to move early after operation and is conducive to the recovery of knee joint function.

    Objective To investigate the effectiveness of one-stage closed reduction and elastic compression fixation with double Kirschner wires for Wehbe-Schneider types ⅠB and ⅡB bony mallet fingers. Methods Between May 2017 and June 2020, 21 patients with Wehbe-Schneider type ⅠB and ⅡB bony mallet fingers were treated with one-stage closed reduction and elastic compression fixation using double Kirschner wires. There were 15 males and 6 females with an average age of 39.2 years (range, 19-62 years). The causes of injury were sports injury in 9 cases, puncture injury in 7 cases, and sprain in 5 cases. The time from injury to admission was 5-72 hours (mean, 21.0 hours). There were 2 cases of index finger injury, 8 cases of middle finger injury, 9 cases of ring finger injury, and 2 cases of little finger injury. The angle of active dorsiflexion loss of distal interphalangeal joint (DIPJ) was (40.04±4.02)°. According to the Wehbe-Schneider classification standard, there were 10 cases of typeⅠB and 11 cases of type ⅡB. The Kirschner wire was removed at 6 weeks after operation when X-ray film reexamination showed bony union of the avulsion fracture, and the functional exercise of the affected finger was started. Results The operation time was 35-55 minutes (mean, 43.9 minutes). The length of hospital stay was 2-5 days (mean, 3.4 days). No postoperative complications occurred. All patients were followed up 6-12 months (mean, 8.8 months). X-ray films reexamination showed that all avulsion fractures achieved bony union after 4-6 weeks (mean, 5.3 weeks). Kirschner wire was removed at 6 weeks after operation. After Kirschner removal, the visual analogue scale (VAS) score of pain during active flexion of the DIPJ was 1-3 (mean, 1.6); the VAS score of pain was 2-5 (mean, 3.1) when the DIPJ was passively flexed to the maximum range of motion. The angle of active dorsiflexion loss of affected finger was (2.14±2.54)°, showing significant difference when compared with preoperative angle (t=52.186, P<0.001). There was no significant difference in the active flexion angle between the affected finger (79.52±6.31)° and the corresponding healthy finger (81.90±5.36)° (t=1.319, P=0.195). At 6 months after operation, according to Crawford functional evaluation criteria, the effectiveness was rated as excellent in 11 cases, good in 9, and fair in 1, with an excellent and good rate of 95.24%. Conclusion For Wehbe-Schneider typesⅠB and ⅡB bony mallet fingers, one-stage closed reduction and elastic compression fixation with double Kirschner wires can effectively correct the deformity and has the advantages of simple surgery, no incision, and no influence on the appearance of the affected finger.

    Objective To analyze the effectiveness of three internal fixation methods, namely hollow screw combined with Kirschner wire tension band, hollow screw combined with anchor nail, and modified 1/3 tubular steel plate, in the treatment of avulsion fracture of tibial tubercle (AFTT) in adolescents. Methods Between January 2018 and September 2023, 19 adolescent AFTT patients who met the selection criteria were admitted. According to different internal fixation methods, patients were divided into group A (8 cases, hollow screw combined with Kirschner wire tension band), group B (6 cases, hollow screw combined with anchor nail), and group C (5 cases, modified 1/3 tubular steel plate). There was no significant difference in the baseline data of age, gender, side, cause of injury, Ogden classification, and time from injury to operation among the three groups (P>0.05). The range of motion (ROM), weight-bearing time, normal activity time of knee joint, and the hospital for special surgery (HSS) score at last follow-up were recorded and compared among the three groups. Recorded whether the fracture was displaced, whether the fracture line was blurred at 1 month after operation, whether there was epiphyseal dysplasia, and whether there was incision infection and other complications. Results There was no significant difference in hospital stay between the groups (P>0.05). All patients were followed up 10-24 months, with an average of 14.3 months; there was no significant difference between the groups (P>0.05). All the incisions healed well without soft tissue irritation or fracture nonunion, and no limb shortening deformity or epiphyseal dysplasia was found during follow-up. At 1 month after operation, the knee joint ROM and hospitalization expenses in group A were better than those in groups B and C, the fracture healing time, knee joint weight-bearing time, and normal activity time of knee joint were better than those in group C, and the hospitalization expenses in group C were better than those in group B, with significant differences (P<0.05); there was no significant difference in the other indicators between the groups (P>0.05). In group A, the fracture line was blurred 1 month postoperatively, the fracture ends were in close contact, and there was no fracture displacement; in groups B and C, the fracture line was clear in 2 cases, and 1 case in group C had slight fracture displacement; except for 1 case in group B, there was no fracture split in the other two groups. There was no significant difference in the incidences of blur of fracture line, fracture displacement, and intraoperative bone split between the groups at 1 month after operation (P>0.05). At last follow-up, the HSS scores of knee joints in the three groups were excellent and good, and there was no significant difference between the groups (P>0.05).ConclusionHollow screw combined with Kirschner wire tension band technique is effective in treating adolescent AFTT, which has the advantages of stabilizing fracture, accelerating fracture healing and rehabilitation, early feasible knee joint functional exercise, and reducing hospitalization expenses.
