This is the largest review to date of THA in patients aged 30 or less. The results show significant functional improvement measured by Harris Hip Score. The revision rate of 5% at 8.4 years is comparable to the general THA population. This contrasts high revision rates reported in older reviews of the literature, suggesting adoption of improved techniques and implants in the more recent literature.

We performed a systematic review to assess whether joint replacement in this very 
young patient group provides significant functional improvement and whether these procedures are associated with good implant survivorship. The studies included presented the results of 
450 THA procedures. All patients showed an improvement in functional score and symptom relief. Uncemented stems showed good integration with no signs of loosening. Cemented implants showed high rates of loosening. This study shows that THA in the very young patient can provide good functional improvement and relief of symptoms and that the more modern uncemented implant designs used with hard-on-hard bearings can be associated with improved implant survival. Long-term studies are necessary to confirm the superiority and improved survivorship of these newer 
implants.

Injury to the superior gluteal artery as a result of pelvic fracture is well recognized. Superior gluteal artery bleed leading to gluteal compartment syndrome without fracture of the pelvis has been reported but is extremely rare. Similarly, acute compartment syndrome of the thigh is rare. As far as is known, no previous case has been reported where a combination of pelvic fracture and superior gluteal artery bleed has led to acute gluteal and thigh compartment syndrome. We report on such a patient who developed these complications and highlight the importance of early detection, which may be difficult in an unconscious or comatose patient.
