Abstract:

BACKGROUND: At present, tension band system is widely used in the treatment of patellar fracture. However, for elderly patients due to osteoporosis and fracture comminution, the stability of patella with traditional tension band fixation is weak, and it is easy to have some problems, such as loss of fracture reduction, and fracture displacement.

OBJECTIVE: To explore the feasibility of double tension band in the treatment of osteoporotic patella fractures in the elderly.

METHODS: Fifteen elderly patients with fresh osteoporotic patellar fracture treated in the Department of

Orthopedic Trauma of the Second Affiliated Hospital of Dalian Medical University from January 2016 to May 2018, including 6 males and 9 females, aged 60-74, were treated with double tension band internal fixation and were not fixed after operation. The time of fracture healing, the occurrence of complications, the range of motion of knee joint and the clinical curative effect score of Bostman patellar fracture were recorded. The study was approved by the Ethics Committee of the Second Affiliated Hospital of Dalian Medical University.

RESULTS AND CONCLUSION: (1) All 15 cases of patellar fracture healed, and the healing time was 2.0-3.0 months. (2) During the follow-up of 12-18 months, all 15 patients had no wound infection, knee joint stiffness, pain and discomfort, fracture re-displacement, loosening and prolapse of internal fixator. (3) At the last follow-up, the range of motion of the knee joint of 15 patients was (127.5±5.8)°, and the range of flexion was reduced by (8.7±6.5)° compared with the healthy side. The functional score of Bostman patellar fracture was excellent in 13 cases and good in 2 cases, with an excellent and good rate of 100%. (4) The results show that the treatment of senile osteoporotic patellar fracture with double tension band fixation can meet the requirements of functional rehabilitation immediately after operation; the fracture fixation is stable and the functional recovery of knee joint is satisfactory.
