RESUMEN
Objective:To investigate the clinical efficacy of arthroscopic limited incision of the articular capsule to repair the glenoid labrum in the treatment of borderline developmental dysplasia of the hip (BDDH) complicated with labral tear.Methods:A retrospective study was conducted to analyze the data of 18 patients with BDDH complicated with labral tear who had been admitted to Department of Orthopaedics, The Second Hospital Affiliated to Suzhou University from January 2016 to December 2019 (observation group). There were 12 males and 6 females with an age of (41.8 ± 8.5) years. Simultaneously, another 18 patients were selected as the control group whose hip development was normal but age and gender were matched with those in the observation group. There were 9 males and 9 females with an age of (43.5 ± 10.3) years. Both groups were treated by arthroscopic limited incision of the articular capsule to repair the glenoid labrum. The 2 groups were compared in terms of modified Harris hip score (MHHS), Hip Outcome Score Activities of Daily Living Subscale (HOS-ADL), and visual analogue scale (VAS).Results:There was no significant difference in the demographic data like age, gender ratio, body mass index, severity of labral tear or time from injury to operation between the 2 groups, indicating comparability between groups ( P>0.05). The observation and control groups were followed up for (38 ± 7) and (43 ± 6) months, respectively. For the observation and control groups, respectively, MHHS was (97.1 ± 3.3) points and (95.4 ± 4.2) points, HOS-ADL (92.6 ± 2.8) points and (91.4 ± 4.1) points, and VAS (0.6 ± 0.5) points and (1.0 ± 0.8) points, all showing no significant difference between groups ( P>0.05). Conclusion:In the treatment of BDDH patients complicated with labral tear, simple arthroscopic limited incision of the articular capsule to repair the glenoid labrum can lead to the same good medium-term efficacy as it can in those with normal hip development.
RESUMEN
BACKGROUND:There were stil lacking related clinical researches in the aspects of whether the total blood loss and hidden blood loss were connected with pathogenesis, whether the total blood loss and hidden blood loss were different among the patients who conducted total hip arthroplasty under different pathogenesis, and whether the preoperative intervention should be conducted for a particular cause? OBJECTIVE:To compare and analyze the hidden blood loss of patients with hip osteoarthritis and femoral neck fracture after total hip replacement. METHODS:The clinical data of 150 patients who received the unilateral total hip arthroplasty treatment from June 2013 to January 2015 were colected and analyzed, including 54 patients with hip osteoarthritis (30 male cases and 24 female cases ), 96 patients with femoral neck fracture (41 male cases and 55 female cases). The pre-and post-operative blood routine and intro-and post-operative blood loss and transfusion were recorded, and hidden blood loss during pen-operation period was evaluated. RESULTS AND CONCLUSION:Total blood loss was (1 616±216) mL, hidden blood loss was (699±102) mL, and hidden blood loss accounted for 43.3% of the total blood loss. The total blood loss was (1 742±254) mL in the hip osteoarthritis group, hidden blood loss was (758±127) mL, hidden blood loss accounted for 44.6% of the total blood loss; The average total blood loss was (1 470±189) mL in the femoral neck fracture group, hidden blood loss was (625±98) mL, hidden blood loss accounts for 42.1% of the total blood loss. The total blood loss and hidden blood loss in hip osteoarthritis group were significantly higher than those in the femoral neck fracture group (P< 0.05). However, there was no significant difference on the hidden blood loss accounts for the proportion of the total blood loss between two groups (P=0.419 3). These results suggest that the total blood loss and hidden blood loss are different for the patients who underwent total hip arthroplasty in the premise of both pathogenesis. Therefore, before the total hip arthroplasty, we should fuly take into account the primary cause of patients and estimate the total blood loss and hidden blood loss, so as to take appropriate preventive measures in time to ensure the safety of the replacement process.
