PurposeShort-term outcomes following cemented and cementless hemiarthroplasties (HAs) are reported to be comparable, however, long-term outcomes of cementless HA—especially among Asian patients—is limited. We aimed to assess long-term outcomes in elderly East-Asian patients with intracapsular proximal femoral fractures treated with cementless HA.Materials and MethodsWe enrolled 135 patients treated with cementless HA who met our inclusion criteria. We documented bone/implant-related complications (e.g., incidences of revision hip surgery, femoral stem subsidence, dislocation, intraoperative and postoperative periprosthetic fractures, contralateral hip fractures). We included those patients who are still alive 10 years after the index surgery in the final functional analysis of the existence of pain, ambulatory status, and residential status.ResultsThe mean age at injury was 78.3 years (range: 60–85 years). At the 10-year follow-up, 26 of the original patients (19.3%) had survived. During follow-up, revision hip surgery was conducted in two patients (1.5%). We recorded the incidence of intraoperative fractures, postoperative periprosthetic fractures, and contralateral fractures in two (1.5%), eight (5.9%), and six patients (4.4%), respectively. Among the 10-year survivors, six patients (23.1% of the survivors) complained of groin pain, but generally reported the pain to be tolerable.ConclusionAmong elderly East-Asian patients, the incidence of revision surgery after cementless HA may be lower than that in their European counterparts, whereas the incidence of periprosthetic fractures can still be considerably higher. For patients undergoing cementless HA, prevention of such secondary fractures is of critical importance.

Study design Single-center, retrospective case-control study. Objectives This study aimed to determine the risk factors for progression of neurological symptoms after anterior fusion for cervical spine trauma with no or incomplete spinal cord injury. Setting Community-based hospital with an acute care center in Japan. Methods We retrospectively reviewed 54 consecutive unstable subaxial cervical spine fracture/dislocation cases that had undergone surgical treatment. A total of 20 patients with no or incomplete spinal cord injury who underwent anterior fusion were identified. Injury characteristics, bony spinal canal diameter (SCD) at the injured level on computed tomography (CT), diagnosis delay of more than 24 h, and other surgery-related parameters were documented as potential risk factors. Results The study population included 16 male and 4 female patients. The median age was 71.5 (range: 20-88) years. Two cases of SCI progression were identified (AIS E to C5-8 C and AIS D to C5-8 C). Both cases occurred in men who were older than the average age of all the patients. Only delayed diagnosis was significantly associated with the progression of SCI (p = 0.02). SCDs on CT demonstrated a tendency to be smaller than those of cases without progression, but this was not statistically significant (progression: median, 8.1 [7.2-8.9] mm; no progression: median, 10.1 [4.2-12.6] mm; p = 0.21). Conclusion Our results suggested that a delay in diagnosis was associated with neurological progression after ACF. Furthermore, imposing ligamentous flavum might become a compression factor if the diagnosis is delayed.
