Long-term effect of interval elbow arthroplasty in the treatment of traumatic elbow stiffness complicated with elbow arthritis in middle-aged and young people
Objective To investigate the clinical effect of interval elbow arthroplasty in the treatment of traumatic elbow ankylosis complicated with elbow arthritis.Methods The clinical data of 11 patients with traumatic elbow ankylosis treated in our hospital from March 2013 to June 2021 were analyzed retrospectively,including 7 males and 4 females,aged from 18 to 47,with an average of(37.46±8.80)years.The causes of trauma included distal humeral fracture(n=4),old elbow dislocation(n=2),intercondylar fracture(n=2),olecranon fracture(n=2)and radial head fracture(n=1),ranging from 6 months to 20 years.The elbow joint activity(range of motion,ROM),visual analogue score of elbow pain(visual analogue scale,VAS),Mayo elbow function score(Mayo elbow-performance score,MEPS)and Barthel index rating scale were compared before and after the last follow-up.Results All the 11 patients completed the operation successfully and were followed up for an average of 88.27(43-130)months.At the last follow-up,the ROM of elbow joint increased from(45.46±17.40)° to(105.55±15.59)°;VAS pain score decreased from(7.45±1.21)to(2.55±1.13);MEPS score increased from(41.36±8.39)to(79.09±5.39);Barthel index increased from(78.64±5.05)to(92.27±4.67),and the differences were statistically significant(P<0.05).No complications such as neurovascular injury,joint instability and recurrent stiffness occurred during the follow-up period.Conclusions Interval elbow arthroplasty can effectively improve the function of the elbow joint and relieve pain in the treatment of traumatic elbow stiffness with elbow arthritis in young and middle-aged patients,and the long-term effect is satisfactory.It can be used as an alternative treatment for traumatic elbow stiffness with elbow arthritis for patients without the willingness of elbow replacement.
