Septic sequelae of hip in children: long-term clinicoradiological outcome study

The presented retrospective study is a report of 18 patients (23 hips) with infantile post sepsis hip sequelae. There were two groups of patients. The observation group comprised of 6 patients (8 hips). The intervention group included 12 patients (15 hips) of which 12 hips had been surgically intervened for the sequelae and 3 contralateral hips which were again serially observed. The sequelae hips were classified by Choi's radiological types. The clinical evaluation was done by modified Moon's criteria. The average patient age at follow-up was 9.3 years. There were 3 type I (13%), 10 type II (43%), 2 type III (8%), and 8 Choi type IV (35%) at presentation. The Choi radiological type showed propensity to change over time/following intervention. At follow-up, there 3 type I (13%), 17 type II (74%), and 3 type IV (13%) hips. At follow-up, there were seven excellent, seven good, and four fair results. The observation group had mostly type I or II and intervention group IIIB or IV Choi types. Findings common to both groups: same Choi radiological type fared different clinically, multiple joint involvement contributed to deterioration of function and late changes in acetabulum or proximal femur lead to deterioration of clinical function. The sequelae of septic hips likely to be kept under supervised observation were Choi type I or II. In select types, intervention changed the natural history of septic sequelae significantly.
