Objective To investigate the effectiveness of femoral troehanter reconstruction and artificial femoral head replacement in treatment of unstable intertrochanterie fractures in the elderly pa- tients. Methods Femoral trochanter reconstruction and artificial femoral head replacement was done on 106 patients with unstable intertrochanterie fractures. There were 45 males and 61 females, at age range of 80-105 years (average 88 years). Most of patients slipt in the room and got fractured. According to the Evans classification, there were 31 patients with type ⅢA fractures, 45 with type ⅢB and 30 with type IV. We used 4 kinds of methods to reconstruct the fracturad imertrochanters : (1) shape of" ∞ " ten- sion band fixation after intertrochanterie fracture reduction;(2) wire loop fixation of the lesser troehanter around proximal femur;(3)defect within the femoral ealear was filled with bone cement and remodeled; (4) for patients with relative intact base of femoral neck, the intertrochanterie fracture was transformed in- to femoral neck fracture and the femoral ealear was fixed with femoral prosthesis stem. Results All the operations continued successfully, with duration of the operation for 45-70 minutes (average 55 minutes). No artificial femoral head dislocation occurred during hospitalization. Of all, 79 patients were followed up for 6-48 months (average 16 months). No Late loosening, dislocation or infections occurred, with total excellence rate of 87.3%. Conclusions For elderly patient with unstable intertrochanterie fractures, reconstruction of femoral intertrochant and artificial femoral head replacement can restore the proximal femoral anatomy, maintain stability of the hip joint and help early functional exeereise, as can reduce ease fatality rate and improve the quality of life.

PurposeVon Hippel-Lindau (VHL) syndrome is a rare autosomal dominant diseases involved multiple organs. This paper aims to explore the clinical and imaging features of VHL syndrome for the improvement of early diagnosis and treatment of this disease.Materials and Methods The clinical and imaging data, as well as their history of 5 patients with VHL syndrome were retrospectively studied. Follow-up was performed and the related literature was also reviewed.Results Among the 5 patients, 4 were found with angioreticulomas. One out of four patients simultaneously suffered from multiple angioreticulomas in brainstem, and another one had multiple cervical cord angioreticulomas. The typical MRI showed multiple cystic and solid mass with mixed intense signals, and the enhanced MRI displayed obvious enhancement in the solid part of the mass. Three patients were diagnosed with renal clear cell carcinomas. The typical CT scan showed equidensity or slightly low density signals, and the enhanced CT scan noted heterogeneous enhancement. Besides, bilateral epididymis cystadenoma occurred in one case. The ultrasonography presented heterogeneous echo and rich blood vessels. The follow-ups had been conducted till January 2015. According to the Glasgow outcome scale, three patients were in good conditions, while the other two died from renal clear cell carcinomas.Conclusion Patients with VHL syndrome usually have an unsatisfactory prognosis and most may die from renal carcinoma. Genetic test and investigation of family history should be performed as early as possible on patients with highly suspected or confirmed VHL Early treatment, life-long follow-up and periodic imaging examinations may be helpful in the prognosis.
