- Arthroscopic Hip Joint Assessment can Impact the Indications for PAO Surgery. [Journal Article]Iowa Orthop J 2019; 39(1):149-157IO
- CONCLUSIONS: Patients in which the PAO was contraindicated, compared to those in which PAO was performed, were older and had significant more severe dysplasia. The main cause of intraoperative disqualification for PAO was advanced articular cartilage disease.Level of Evidence: IV.

To explore the effect of application of soft tissue loosening and acetabular reconstruction in hip replacement for patients with severe femoral head necrosis on joint function. Methods: From June 2012 to August 2016, 68 patients with severe femoral head necrosis (Ficat III, IV) underwent total hip replacement with soft tissue release and acetabular reconstruction at the Second Xiangya Hospital of Central South University. Total hip replacement is performed by the posterolateral approach. The acetabulum was rebuilt and the length of the affected limb was prolonged after clearing the scar tissue, proliferating the epiphysis, releasing the abductor muscle group and the adductor muscle group, dissecting the soft tissue around the acetabulum. One year after surgery, Harris score, X-ray positive lateral radiograph for the affected side and full-length X-ray examination for both lower extremities were performed to evaluate the curative effect. Results: The postoperative follow-up time ranged from 1.0 to 5.5 years. All patients' femoral heads returned to normal anatomical position and the affected limb length was restored to 1.5-3.5 cm; all patients did not damage the sciatic nerve. The Harris scores for 68 patients increased from 38.6±7.5 to 78.2±5.7 (P=0.029) in the first year after surgery. Conclusion: During hip replacement surgery for severe femoral head necrosis, soft tissue dissection and acetabular reconstruction can be used to ensure anatomical reconstruction for the acetabular fossa and to improve abductor function.
- Acetabular Lateral View: Effective Fluoroscopic Imaging to Evaluate Screw Penetration Intraoperatively. [Journal Article]Med Sci Monit 2019; 25:5953-5960MS
- CONCLUSIONS: Use of the lateral view of the acetabulum can be a complementary method to identify malpositioned screws, and it helps increase the accuracy rate of inserting screws in the treatment of posterior wall fracture.
- Ex vivo biomechanical comparison of 2.7 mm string-of-pearl plate versus screw/wire/Polymethylmethacrylate composite fixation and 2.7 mm veterinary acetabular plate for repair of simulated canine acetabular fractures. [Journal Article]BMC Vet Res 2019; 15(1):287BV
- CONCLUSIONS: Although the ease of application for the String-of-Pearls™ implant was subjectively better than other implants, no significant differences were found in fracture reduction scores. The String-of-Pearls™ constructs were stiffer than veterinary acetabular plates and exhibited greater failure and ultimate loads compared to veterinary acetabular plates and screw/wire/polymethylmethacrylate fixations. The String-of-Pearls™ implant appears to be a suitable fixation choice for simple canine acetabular fractures.
- Nerve injury with acetabulum fractures: Incidence and factors affecting recovery. [Journal Article]J Orthop Trauma 2019JO
- CONCLUSIONS: Posterior acetabulum fracture dislocations are associated with traumatic nerve injury, although 25% of nerve injuries were iatrogenic. Nerve injuries are more common in obese patients. Over one quarter of patients had no recorded nerve recovery.
- Acetabular Subchondral and Cortical Perforation During Labral Repair With Suture Anchors: Influence of Portal Location, Curved Versus Straight Drill Guides, and Drill Starting Point. [Journal Article]Arthroscopy 2019; 35(8):2349-2354A
- CONCLUSIONS: The use of the DALA portal and a drill starting point slightly off the acetabular rim was associated with the lowest rate of acetabular subchondral perforation and is recommended to reduce the risk of iatrogenic chondral injury.Iatrogenic chondral injury is a relatively common complication of hip arthroscopy. Increased awareness of factors associated with drill perforation during suture anchor placement can help surgeons mitigate this risk.
- Editorial Commentary: Is the Lateral Center-Edge Angle Sufficient for the Approximation of Acetabular Coverage? [Editorial]Arthroscopy 2019; 35(8):2346-2348A
- The lateral center-edge angle is a robust technique with proven clinical applicability for quantifying acetabular coverage. However, it measures only the lateral coverage of the femoral head without consideration of other important portions of the acetabulum such as the anterior or posterior wall. Three-dimensional acetabular coverage measurement techniques capable of quantifying the entire aceta…
The lateral center-edge angle is a robust technique with proven clinical applicability for quantifying acetabular coverage. However, it measures only the lateral coverage of the femoral head without consideration of other important portions of the acetabulum such as the anterior or posterior wall. Three-dimensional acetabular coverage measurement techniques capable of quantifying the entire acetabulum have become available, thus posing the question of whether we should still rely on the lateral center-edge angle for the assessment of acetabular coverage.
- Does Orientation of the Femoral Head Affect Acetabular Development? An Experimental Study in Lamb. [Journal Article]J Pediatr Orthop 2019; 39(8):416-421JP
- CONCLUSIONS: Decreasing the neck-shaft angle provokes an increase in acetabular volume, whereas changes in femoral version do not affect the acetabular growth. Extra-articular osteotomies that alter femoral orientation affect intra-articular gross morphology.
- Acetabular Version Increases During Adolescence Secondary to Reduced Anterior Femoral Head Coverage. [Journal Article]Clin Orthop Relat Res 2019CO
- CONCLUSIONS: With skeletal maturity, acetabular version increases, especially rostrally. This increase is associated with, and is likely a result of, a reduced anterior acetabular sector angle (that is, less coverage anteriorly, while the degree of coverage posteriorly remained the same). Thus, in patients were the normal developmental process is disturbed, a rim-trim might be an appropriate surgical solution, since the degree of posterior coverage is sufficient and no reorientation osteotomy would be necessary. However, further study on patients with retroversion (of various degrees) is necessary to characterize these observations further. The changes in version were not associated with any of the tested patient factors; however, further study with greater power is needed.
