Objective To investigate the radiological and clinical features of osteoarthrosis in congenital insensitivity to pain with anhidrosis (CIPA).Methods The clinical and radiological features in 8 cases of CIPA diseases were retrospectively analyzed. There were five males and three females,age ranged from 11 to 18 years with a median age of (14±3) years. X-ray plain film findings in eight cases were analyzed for the location, extent and contour of the lesions, surrounding bony sclerosis, as well as joint and soft tissue changes. Results The main clinical presentations were insensitivity to pain, anhydrosis, fever, mental retardation and infection. In these eight cases, a total of 166 pieces of bone were involved, including the plantar and phalanges (n=115),phalanx (n=29).The radiological findings include dissolution of the entire bone or most of the bone (n=113), dissolution of a few small areas of the bone (n=40), dissolution of the bone with only residual punctate areas (n=7), the“pushpin sign”and“pencil tip sign”and“flat cut sign”of the finger osteolysis (n=6), sclerosis of peripheral bone (n=12), pathological fractures (n=2). Joint dislocation (n=3),joint deformity (n=3), and Charcot joint (n=3) were observed.Necrosis of soft tissue(n=4), complete absence of soft tissue in the finger or toe (n=4), dot-like calcification of the soft tissue(n=3) were also observed. Conclusion Osteoarthrosis in patients with CIPA had certain X-ray and clinical characteristic findings, which could facilitate its diagnosis.

[Objective] To evaluate the effect of fast rehabilitation nursing pathway in patients after artificial hip replacement.[Methods] 86 patients underwent artificial hip replacement were randomly divided into the control group and the experimental group with 43 cases in each group.The control group received routine care,while the experimental group was given fast rehabilitation nursing pathway.Anxiety and pain at 48h after operation were evaluated,and hip joint function(Harris score)was evaluated six months after operation.[Results] Compared with the control group,anxiety and pain score at 48h after operation decreased markedly,and Harris score six months after operation increased significantly.[Conclusions] Fast rehabilitation nursing pathway can reduce both the short-term and long-term efficacy of patients after artificial hip replacement.
