Abstract Lengthening of the humerus has been accomplished with distraction osteogenesis using a variety of external fixators, including traditional monolateral, Ilizarov-type, and multiaxial correction frames. Recently, highly reliable and accurate motorized intramedullary nails have become available. The aim of this study is to systematic review and met analysis the results of humeral lengthening which included the studies published between 1990 and 2022 Regarding the type of included studies, there were nine studies included. Six studies were retrospective and three studies were intervention, with total number of 173 humeri in 144 patients. Publication bias was minimal for those 8 studies included and most studies were underpowered. Major finding in the study: The age of patients across the studies ranges between 6.5 and 24 years. The male gender was common and ranging from 33% to 78%. There are no statically significant differences between the studies included regarding age and sex. The mean length achieved was 7.7 cm among the included 8 studies ranging from 5.1 cm to 9 cm. The pooled analysis of the included studies showed significant association between length pre and post humeral lengthening. There is no statically significant difference between the studies included regarding length achieved. There is no statically significant difference between the studies included regarding pre and post-operative range of movement which means that lengthening of humerus does not affect the range of movement. There is no statically significant difference between the studies included regarding pre and post-operative functional score of shoulder which means that lengthening of humerus does not affect the functional score of shoulder. |
