Study: Role of Acetabular Retroversion in Femoroacetabular Osteoplasty

A study published online in The Journal of Arthroplasty assessed outcomes in femoroacetabular osteoplasty (FAO) patients with or without acetabular retroversion. From 2007 to 2015, 51 patients (29 male) with acetabular retroversion underwent FAO; two-year clinical and radiological outcomes were compared to that of 550 patients without acetabular retroversion who underwent FAO by the same surgeon. Mean patient age was 27.4 years in the retroversion group and 34.5 years in the control group, and patients were followed for a mean of 4.8 years and 4.1 years, respectively. At final follow-up, the retroversion group had significantly lower mean modified Harris Hip Score (75.4) and 36-Item Short Form Health Survey (76.5) compared to the control group (83.4 and 85.6, respectively). Retroversion patients had a higher failure rate compared to the control group (13.7 percent versus 2.5 percent).

Study Compares Variables Associated with Screws in Patella Fracture

A study published online in BMC Musculoskeletal Disorders compared outcomes associated with various screw types at different locations with and without the anterior wire in patella fractures. Three types of screws were evaluated—partial thread, full thread, and headless compression screws—as well as two screw depths—5 mm and 10 mm away from the anterior surface of the patella. The researchers recommended using the anterior wire along with the full thread screw to maintain the reduction of the transverse patellar fracture. Full thread screws at a 5 mm placement could reduce surgical trauma during the open anterior wiring, according to the findings.

Study: Surgical Versus Nonsurgical Treatment for Clavicle Fracture

Operative treatment may provide better outcomes for displaced midshaft clavicle fracture (MCF) patients compared to nonoperative treatment, according to a meta-analysis published online in The American Journal of Sports Medicine. Researchers queried PubMed, Web of Science, Cochrane library, and grey literature for relevant randomized, controlled trials (RCTs). The primary outcome was nonunion rate, and other outcomes included time to union and return to activities; Constant score; and Disabilities of the Arm, Shoulder and Hand (DASH) index. Final analysis included 14 RCTs comprising 1,546 patients. The risk ratio for nonunion was significantly lower among operative patients, and time to union was 5.1 weeks shorter with surgery. The surgical group had a higher complication rate (31.3 percent) than the nonsurgical group (20.5 percent). Short-term follow-up of shoulder function was favorable for the surgical group, while midterm follow-up showed no statistical differences for the Constant score or DASH index. At long-term follow-up, the operative cohort had better outcomes in terms of the Constant score (mean difference, 5.3 points) and DASH index (mean difference, 4.3 points).

Study: Deep Drainage in Scoliosis Patients May Not Improve Spinal Fusion Outcomes

Posterior spinal fusion (PSF) with drainage may not be advantageous over PSF without drainage in adolescent idiopathic scoliosis (AIS) patients, according to an RCT published in the March 15 issue of Spine. A total of 100 AIS patients were randomized to undergo PSF with (n = 48) or without (n = 52) a deep drain. Patients were followed for a mean of 20 months. During postoperative days one to three, fever was comparable in both groups but increased in the no drain group on day six. Length of stay was six days in both cohorts. There were no instances of deep infection. Complications included one case of pneumonia in the no drain group, wound dehiscence in two cases in the no drain group and in one case in the drain group, and two cases of superficial wound infection in the no drain group.

Study Evaluates Relationship Between MicroRNAs and Fracture

A study published online in the Journal of Bone and Mineral Research assessed the serum levels of 32 preselected microRNAs (miRNAs) with reported function in bone and their association with osteoporotic fracture. Researchers measured serum levels of the miRNAs in 99 premenopausal and 583 postmenopausal women; one and 122 women, respectively, had prevalent fragility fractures in each group. Several miRNAs were associated with prevalent or incident fragility fractures, bone turnover markers, bone mineral density, and microarchitecture, but the association was not significant after adjusting for age.

AAOS and the Musculoskeletal Tumor Society Introduce Musculoskeletal Tumor Registry Pilot

AAOS, in collaboration with the Musculoskeletal Tumor Society, announced the launch of a Musculoskeletal Tumor (MsT) Registry feasibility pilot to begin capturing data on orthopaedic oncology bone tumor procedures in a structured and scalable way. Six major U.S. academic centers were selected to participate in the year-long program. The MsT Registry pilot is the third in a series of registries developed as part of the AAOS Registry program.
