Systematic review of total hip arthroplasty in patients under 30 years old.

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.

Acute Gluteal and Thigh Compartment Syndrome following Pelvic Fracture and Superior Gluteal Artery Bleed : A Case Report and Review of the Literature.

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.
