Abstract:
OBJECTIVE:To investigate the clinical effects of dual mobility total hip prosthesis in treating femoral neck fracture patients with hemiplegia.
METHODS:A retrospective analysis was performed on 18 patients with femoral neck fracture combined with hemiplegia who underwent dual mobility total hip prosthesis replacement from March 2014 to December 2016. The follow up data of these patients was complete. There were 5 males and 13 females, aged 65 to 70 years old with an average of (66.50±1.38) years. The left side was involved in 12 cases, while the right side in 6 cases. There were 4 cases with Garden Ⅲ type and 14 cases with type Ⅳ. Limb muscle strength of hemiplegia were in grade Ⅳ. The posterior-lateral approach of hip joint was used in surgery for all patients. The implant position, dislocation and loosening of the prosthesis were evaluated by X-ray examination. Harris hip score and the Merle D'aubigne score were used to assess the hip function in the follow up.
RESULTS:The operation duration was for 70-90 (81.56±7.48) min and the blood loss during the operation was for 160-200 (170.32± 12.56) ml. No blood was transfused during the operation. Postoperative incisions were healed at the first stage. The follow-up time was for 28-60(36.0±3.5) months. Harris hip score increased from 16.94±0.73 preoperatively to 96.19±1.27 at the final follow-up(<0.05). Merle D 'Aubigne score increased from 3.96±0.06 preoperatively to 16.81±0.63 at the final follow-up(< 0.05). No fracture or nerve or vascular injury were found during the operation. The postoperative X-ray showed that the prosthesis was in good position. No complications such as joint dislocation, dislocation of prosthesis, loosening of prosthesis, fracture around the prosthesis, pain in the front of thethigh, fracture of the self tapping screw in the ilium, and delayed infection occurred in the patients after operation.
CONCLUSION:Dual mobility total hip prosthesis has the advantages of both good initial stability and low dislocation rate of the prosthesis, and the clinical application of total hip replacement in hemiplegic femoral neck fracture is satisfactory.
