ABSTRACT
OBJECTIVE:
To evaluate the effect of fracture and subsequent repair on future bone growth of the humerus after Salter-Harris type IV fracture of the lateral part of the humeral condyle (LPHC). STUDYDESIGN:
Prospective study. ANIMALS Dogs (n=11).METHODS:
Dogs that had LPHC fracture and an open distal humeral physis repaired (1992-2006) were re-examined and radiographed at >or=12 months of age and humeral length was measured.RESULT:
Measurements from 11 dogs showed a significant (P=.02) increase in length of the humeral diaphysis of the affected leg compared with that of the intact limb (median, 1.2%; range, 1.3-3.4%). Condylar deformity secondary to growth disturbance was not observed.CONCLUSION:
Shortening or growth deformity was not observed after fracture and repair even if a transcondylar screw was placed through the distal humeral growth plate. A mild overgrowth of the humeral diaphysis was observed, although likely considered clinically unimportant. CLINICAL RELEVANCE Fracture of the LPHC and subsequent repair in dogs >3 months of age do not impair growth of the humeral diaphysis. A transcondylar humeral screw placed through the humeral physis will not result in shortening of the humeral diaphysis. Implant removal to allow for further growth is therefore not indicated.
