Clinical Effectiveness of Home-Based Telerehabilitation Program for Geriatric Hip Fracture Following Total Hip Replacement.

OBJECTIVE: To compare the effectiveness of a six-month home-based telerehabilitation based on the Internet-based rehabilitation management system coupled with conventional outpatient care in elderly patients with hip fractures following total hip replacement (THR). METHODS: Elderly patients (aged over 65 years) with first hip fractures who underwent THR between March 2018 and September 2018 in Tianjin Hospital were enrolled in this study. Patients were divided into two groups: telerehabilitation group (n = 43) and telephone group (n = 42). A Internet-based telerehabilitation management system was established and applied on patients in the telerehabilitation group. For patients in the telephone group, the rehabilitation intervention was administered through conventional outpatient care (telephone along with outpatient follow-up). Data from the Harris hip scale (HHS), functional independence measure (FIM), self-rating anxiety scale (SAS), and postoperative complications at 1, 3, and 6 months after surgery were collected and compared between the two groups. RESULTS: A total of 85 elderly patients completed the 6-month follow-up assessment. Results showed that the HHS score was significantly higher in the telerehabilitation group than in the telephone group at 1 month (66.35 ± 4.63 vs 63.48 ± 4.49), 3 months (76.33 ± 4.52 vs 71.81 ± 3.84), and 6 months (84.23 ± 3.13 vs 77.29 ± 4.95) after surgery (P < 0.001). The FIM score was significantly higher in the telerehabilitation group than in the telephone group at 1 month (89.00 ± 5.63 vs 73.35 ± 8.70), 3 months (100.16 ± 4.56 vs 92.81 ± 5.17), and 6 months (111.70 ± 3.13 vs 98.64 ± 5.12) after surgery (P < 0.001). The SAS score was significantly lower in the telerehabilitation group than in the telephone group at 1 month (42.40 ± 3.07 vs 46.21 ± 3.53), 3 months (36.77 ± 2.26 vs 40.24 ± 1.66), and 6 months (29.26 ± 1.63 vs 33.81 ± 2.62) after surgery (P < 0.001). The overall complication rate was significantly lower in the telerehabilitation group than in the telephone group (14% vs 40.5%) (P < 0.05). CONCLUSION: Internet-based rehabilitation management system can not only promote the physical rehabilitation of patients, but also play a positive role in psychological rehabilitation and the prevention of complications, which provides new ideas and methods for clinical rehabilitation.

Preoperative Plan with 3D Printing in Internal and External Fixation for Complex Tibial Plateau Fractures.

OBJECTIVE: To compare short-term treatment effects of internal and external fixation in the treatment of complicated tibial plateau fractures by preoperative planning with 3D printing. METHODS: Sixty-nine patients with tibial plateau fractures were examined. 3D printing was used to establish the model in all patients before the operation. Thirty-four patients were treated with an external fixator (9-Schatzker Type V, 25-Schatzker Type VI) and 35 patients were treated with internal fixation (12-Schatzker Type V, 23-Schatzker Type VI). The time span of the study was 2 years after the operation. All patients were followed up in the clinic of the attending physician who recorded patient follow-up information at the same time. Finally, the Rasmussen functional score, radiographic parameters, complication rates, hospital days and operative parameters of the two groups were analyzed. RESULTS: The short-term (within 2 years) Rasmussen score in the external fixation group was close to that of the internal fixation group; the differences were not significant (P > 0.05). The fractures were reduced adequately using both forms of surgical treatment. There is no significant difference between internal and external fixation in terms of radiographic parameters after 2 years (Mann-Whitney U-tests, P > 0.05). Thrombosis was detected in 7 cases (2 external fixation, 5 internal fixation). Superficial infection was detected in 3 cases (1 external fixation, 2 internal fixation). Deep infection was detected in 3 cases (0 external fixation, 3 internal fixation). Knee stiffness was detected in 4 cases (2 external fixation, 2 internal fixation); 1 (2.7%) case of screw pullout occurred in the internal fixation group. The external fixation group had shorter operation times (172.94 ± 50.00 min vs 253.86 ± 64.59 min), less bleeding volume (395.88 ± 121.10 mL vs 864.29 ± 238.12 mL), and fewer days (17.03 ± 5.03 days vs 30.17 ± 8.64 days) of hospitalization compared to the internal fixation (t-test, P = 0.00); subgroup analysis of all patients with complex tibial plateau fractures revealed that for patients with tibial plateau fracture type VI, the functional score of external fixation (26.79 ± 2.04) is better than that (25.54 ± 1.69) of internal fixation (t- test, P = 0.026) and the overall infection rate of external fixation is lower than that of internal fixation (χ2 - test, P = 0.047). CONCLUSION: Using 3D printed models in combination with external fixation has more advantages for short-term treatment of complex tibial plateau fractures. In particular, relatively better functional recovery and lower rates of infection can be achieved for Schatzker type VI fractures. The external fixation treatment was preferred in cases of Schatzker VI tibial plateau fractures.
