Study: High Rate of Serious Complications, Mortality in Elective THA in Patients Aged ≥90 Years
Elective total hip arthroplasty (THA) in patients aged ≥90 years is associated with significantly increased risk of postoperative complications and mortality, according to a retrospective study published online in The Journal of Arthroplasty. The National Surgical Quality Improvement Program database was queried, and 74,361 THA patients aged ≥65 were included. There were 1,119 patients (1.5 percent) aged ≥90 years. In this subgroup, the rates of major life-threatening complications, minor complications, and death were 1.3 percent, 2.8 percent, and 0.2 percent, respectively. Age was a significant risk factor for complications and mortality.

Study: Shoulder Kinematics after LDT for Pseudoparalytic Massive Irreparable RC Tear
A study published online in the Journal of Shoulder and Elbow Surgery reported that thoracohumeral (TH) motion improved after latissimus dorsi transfer (LDT) in a pseudoparalytic massive irreparable posterosuperior rotator cuff (RC) tear. However, glenohumeral (GH) motion was impaired compared to the asymptomatic shoulder Thirteen patients were followed for at least one year. Maximal active elevation of the shoulder (MEAS) for TH motion was comparable between the LDT and asymptomatic shoulder postoperatively, but GH motion was significantly lower in the LDT shoulder for all motions.

| Randomized Study Investigates Foot Interventions for Reducing Patellofemoral Pain
A randomized study published online in BMC Musculoskeletal Disorders found that foot interventions (i.e., talonavicular joint mobilization [TJM] and foot core strengthening [FCS]) reduced pain and improved function in patients with patellofemoral pain syndrome. Forty-eight patients were randomized to 12 sessions of either TJM, FCS, or a blended intervention. TJM reduced pain more than FCS at four weeks postintervention. The blended intervention improved lower extremity function and valgus knee better than TJM and led to greater improvements in muscle activity than either treatment alone. TJM and the blended intervention were more effective at improving foot posture than FCS.

| Study: Blade-stopping Mechanism in Circular Table Saws Does Not Prevent All Traumatic Hand Injuries
An in vitro study published in the Journal of Hand Surgery reported that a modern blade-stopping technology for circular table saws (used in woodworking) did not prevent all traumatic hand injuries in scenarios of fast approach speed. Twenty-seven hand specimens were used to assess three injury scenarios: moving forward, moving backward, and being dropped from above the saw blade. Each scenario was tested at a slow and fast speed. The brake cartridge engaged in all slow-speed scenarios. At the fast speed, the brake engaged in 89 percent of forward moving trials, 11 percent of backwards trials, and 89 percent of above-the-blade trials.

| Study Compares Posterior Spinal Fusion Techniques for Correction of Adolescent Idiopathic Scoliosis with Thoracic Deformity
A retrospective study published online in the European Spine Journal found similar correction of the coronal plane between four techniques for performing posterior spinal fusion for adolescent idiopathic scoliosis with thoracic deformity (in situ bending [ISB], rod derotation [RD], cantilever [C], posteromedial translation [PMT]). In total, 562 patients with two years of follow-up were evaluated. Though coronal correction rates were significantly different between treatment groups, implant density, convex side compression, and use of derotation connectors were associated with correction rate, while surgical technique was not. Greater thoracic kyphosis restoration was associated with reduction technique and preoperative thoracic kyphosis.

Interviews with International Orthopaedic Association Presidents
The February issue of AAOS Now featured interviews with several presidents of international orthopaedic associations, including Hee Joong Kim, MD, president of the Korean Orthopaedic Association; Andrés Silberman, MD, president of the Argentina Orthopaedic and Trauma Association; and Kalin Mihov, MD, PhD, president of the Bulgarian Association of Arthroscopy and Sports Traumatology. In interviews with AAOS Now Editorial Board members, the presidents talked about orthopaedics in their home country, differences between their healthcare systems and that of the United States, and more.
