Risk of Thromboembolism in Shoulder Arthroplasty: Effect of Implant Type and Traumatic Indication

Ronald A. Navarro MD, Maria C. S. Inacio MS, Mary F. Burke MPH, John G. Costouros MD, Edward H. Yian MD

Prior research about symptomatic venous thromboembolism (VTE) after shoulder arthroplasty has not determined whether procedure type (hemiarthroplasty, total shoulder arthroplasty, or reverse shoulder arthroplasty) or surgical indication (traumatic or elective) represent risk factors for VTE after shoulder replacement.

Surgical Technique: Simple Technique for Removing a Locking Recon Plate With Damaged Screw Heads

Nirmal Raj Gopinathan (MS)Ortho, Mandeep Singh Dhillon (MS)Ortho, Rajesh Kumar (MS)Ortho

The introduction of locking plates in the treatment of periarticular fractures was a major breakthrough in orthopaedic evolution. Removal of these implants is extremely difficult as a result of cold welding and stripping of screw heads.

The Natural Course of Serratus Palsy at 2 to 31 Years

Veera Pikkarainen MD, Jyrki Kettunen PT, PhD, Martti Vastamäki MD, PhD

The natural course of isolated serratus palsy is obscure. Residual winging, muscle weakness, and fatigability reportedly occur in half of the patients. Because we believed isolated serratus palsy might have a better natural course than earlier thought, we evaluated our long-term records.

Lateralized Reverse Shoulder Arthroplasty Maintains Rotational Function of the Remaining Rotator Cuff

Stefan Greiner MD, Christan Schmidt, Christian König Dr Ing, Carsten Perka MD, Sebastian Herrmann MD

Humeral rotation often remains compromised after nonlateralized reverse shoulder arthroplasty (RSA). Reduced rotational moment arms and muscle slackening have been identified as possible reasons for this impairment. Although several clinical studies suggest lateralized RSA may increase rotation, it is unclear whether this is attributable to preservation of rotational moment arms and muscle pretension of the remaining rotator cuff.

3-D CT is the Most Reliable Imaging Modality When Quantifying Glenoid Bone Loss

Julie Y. Bishop MD, Grant L. Jones MD, Michael A. Rerko MD, Chris Donaldson MD

Posttraumatic anterior shoulder instability is associated with anterior glenoid bone loss, contributing to recurrence. Accurate preoperative quantification of bone loss is paramount to avoid failure of a soft tissue stabilization procedure as bone reconstruction is recommended for glenoid defects greater than 20% to 27%.

Immediate Postoperative Radiographs After Shoulder Arthroplasty Are Often Poor Quality and Do Not Alter Care

Surena Namdari MD, MSc, Jason E. Hsu MD, Matthew Barron BS, G. Russell Huffman MD, MPH, David Glaser MD

It is technically difficult to obtain high-quality, postoperative shoulder radiographs immediately after surgery. Further, poor-quality radiographs may be unlikely to change clinical practice or improve patient outcomes. We therefore questioned the value of routine postoperative radiographs after shoulder arthroplasty.

Does Humeral Lengthening With a Monolateral Frame Improve Function?

Abhijit Y. Pawar MD, Thomas H. McCoy MD, Austin T. Fragomen MD, S. Robert Rozbruch MD

Humeral lengthening by distraction osteogenesis historically has relied on bulky circular external fixators. Advances in fixator technology have allowed for the use of monolateral frames. However, it is unclear whether and to what degree function is improved after humeral lengthening.

Motion and Pain Relief Remain 23 Years After Manipulation Under Anesthesia for Frozen Shoulder

Heidi Vastamäki MD, Martti Vastamäki MD, PhD

Manipulation under anesthesia (MUA) as treatment for idiopathic frozen shoulder increases motion, provides pain relief, and restores function, but it is unclear whether the improvements persist long term.

To What Degree do Shoulder Outcome Instruments Reflect Patients’ Psychologic Distress?

Young Hak Roh MD, Jung Ho Noh MD, Joo Han Oh MD, Goo Hyun Baek MD, Hyun Sik Gong MD

Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores.

Rotator Cuff Integrity Correlates With Clinical and Functional Results at a Minimum 16 Years After Open Repair

Martti Vastamäki MD, PhD, Martina Lohman MD, PhD, Niclas Borgmästars MD

Recurrent or persistent defects in the rotator cuff after its repair are common. Short- and medium-term surveys have revealed, after open repair, patients with an intact rotator cuff have increased function and ROM. However, no long-term studies have verified cuff integrity on MR arthrography or correlated it with clinical and functional outcomes.
