Osteochondral Autograft Transplantation for Capitellar Osteochondritis Dissecans.

Authors:
Dan A Zlotolow

JBJS Essent Surg Tech 2021 Apr-Jun;11(2). Epub 2021 May 12.

Shriners Hospitals for Children, Philadelphia, Pennsylvania.

Background: The goal of the osteochondral autograft transplantation (OAT) procedure is to replace both the bone and cartilage that have been compromised by osteonecrosis of the capitellum, a condition known as osteochondritis dissecans (OCD). In children, the vascularity of the capitellum is limited compared with that in adults because the physis acts as a physical barrier to vascular ingrowth from the metaphysis to the epiphysis. The necrotic subchondral bone cannot keep up with the weight-bearing demands of certain high-level athletes such as gymnasts, accumulating microfractures and eventually crumbling. Read More

Scaphoid Nonunion Volar Plating with Pure Nonvascularized Cancellous Autograft.

JBJS Essent Surg Tech 2021 Apr-Jun;11(2). Epub 2021 May 27.

Department of Orthopaedic Surgery, University of Arizona College of Medicine-Phoenix, Phoenix, Arizona.

Background: Surgical treatment of scaphoid nonunion has evolved over the years to include a variety of procedures and techniques involving a number of vascularized and nonvascularized bone grafting options and fixation strategies. Volar plating of scaphoid nonunions with use of pure cancellous nonvascularized autograft is a safe and effective treatment method with good functional outcomes and union rates.

Description: Volar plating of the scaphoid nonunion is performed via a volar approach, with debridement and reduction of the nonunion site. Read More

The humeral head: A review of the blood supply and possible link to osteonecrosis following rotator cuff repair.

J Anat 2021 Jun 23. Epub 2021 Jun 23.

Department of Anatomy and Cellular Biology, College of Medicine and Health Sciences, Khalifa University, Abu Dhabi, United Arab Emirates.

Trauma, corticosteroid therapy and metabolic diseases are well established aetiologies of humeral head osteonecrosis; however, there is increasing evidence that arthroscopic rotator cuff surgery may be another possible cause. One of the reasons is that there may be inadvertent damage to the arterial blood supply to the humeral head during surgical intervention. The blood supply to the humeral head displays large amounts of variation with regard to origin, course and distribution. Read More

Pyrocarbon Humeral Head in a Shoulder Hemiarthroplasty: Preliminary Results at 3 Years Follow-Up and Review of the Current Literature.

Case Rep Orthop 2021 14;2021:6633690. Epub 2021 Apr 14.

Department of Orthopedics, Centro Hospitalar e Universitário do Porto, Portugal.

Shoulder hemiarthroplasty is a viable option in young patients with an intact rotator cuff in order to preserve the native glenoid. To avoid the dreaded and expected wear of the glenoid in very active shoulders, implants with humeral head coated with a high resistant and elastic material-pyrolytic carbon-are now an option. The authors present the first pyrocarbon coated hemishoulder arthroplasty performed at our Orthopedic Department in a patient with osteonecrosis of the humeral head. Read More

Complications Associated with Posterior Cruciate Ligament Reconstruction and Avoiding Them.

J Knee Surg 2021 May 5;34(6):587-591. Epub 2021 Feb 5.

Division of Sports Medicine and Shoulder Surgery, Hospital for Special Surgery, New York City, New York.

Posterior cruciate ligament (PCL) injuries often occur as part of a multiligament injury pattern and can present a significant challenge to the treating surgeon. When PCL reconstruction is indicated, complications can arise in the intraoperative and postoperative period that lead to poor outcomes. These complications include neurovascular injury, fracture, compartment syndrome, persistent posterior laxity, motion loss, residual knee pain, osteonecrosis, and heterotopic ossification. Read More

R Lancigu L Rony

Morphologie 2021 Jun 21;105(349):148-154. Epub 2021 Jan 21.

Département de chirurgie osseuse, CHU Angers, 4, rue Larrey, 49933 Angers cedex 9, France; GEROM - Groupe Etudes Remodelage Osseux et bioMatériaux, IRIS-IBS institut de biologie en santé, université d'Angers, 49933 Angers, France.

Aseptic osteonecrosis of the humeral head is a multifactorial entity in which the final common pathway results in disrupted blood supply, increased intraosseous pressure, and bone death. It follows a pathologic and radiographic pattern of progression similar to that seen at the hip. Much of the information regarding the disease has been extrapolated from findings in the femoral head.

Shoulder Osteonecrosis: Pathogenesis, Causes, Clinical Evaluation, Imaging, and Classification.

Orthop Surg 2020 Oct 4;12(5):1340-1349. Epub 2020 Oct 4.

Clinique St. Michel, Groupe ELSAN, Toulon, France .

The humeral head is the second most common site for nontraumatic osteonecrosis after the femoral head, yet it has attracted relatively little attention. Osteonecrosis is associated with many conditions, such as traumatism, corticosteroid use, sickle cell disease, alcoholism, dysbarism (or caisson disease), and Gaucher's disease. The diagnosis is clinical and radiographic with MRI, with radiographs being the basis for staging. Read More

J Am Acad Orthop Surg 2020 Oct;28(19):781-789

From the University of Texas Southwestern Medical Center (Dr. Khazzam), Dallas, TX, the University of Washington Medical Center (Dr. Gee), Seattle, WA, the Kaiser Permanente in Los Angeles (Dr. Pearl), and the University of Southern California (Dr. Pearl), Los Angeles, Los Angeles, CA.

The Management of Glenohumeral Joint Osteoarthritis Evidence-Based Clinical Practice Guideline is based on a systematic review of published studies for the treatment of glenohumeral joint osteoarthritis. The purpose of this clinical practice guideline is to address the management of patients with glenohumeral joint osteoarthritis. It is not intended to address the management of glenohumeral joint arthritis from etiologies other than osteoarthritis (ie, rheumatoid arthritis, inflammatory arthritis, posttraumatic arthritis, osteonecrosis, rotator cuff tear arthroplasty, capsulorrhaphy arthroplasty, and postinfections arthroplasty) This guideline contains 13 recommendations to assist all qualified and appropriately trained healthcare professionals involved in the management of glenohumeral joint osteoarthritis.

Dysbaric osteonecrosis in technical divers: The new 'at-risk' group?

Diving Hyperb Med 2020 Sep;50(3):295-299

Department of Anaesthesiology, Faculty of Medicine and Health Sciences, The University of Auckland, Auckland, New Zealand.

Introduction: Dysbaric osteonecrosis (DON) in people working under increased atmospheric pressure is well documented. It is generally less common in military and commercial divers than in caisson workers, except in some high-risk groups, such as in many indigenous diving industries where workers have little or no understanding of decompression principles. With the increasing popularity within the recreational diving community of deep air and mixed-gas decompression diving ('technical diving'), it is likely that diving physicians may see an increase in the prevalence of DON in this group in the future.

Humeral head necrosis associated to shaft non-union with massive bone loss: a case report.

Acta Biomed 2020 09 7;91(3):e2020076. Epub 2020 Sep 7.

Politecnico di Milano.

Humeral non-union is a rare complication in shaft fractures, as well as humeral head necrosis is a possible complication in fracture involving the proximal third especially in four-part fractures. The presence of head osteonecrosis and diaphyseal non-union in the same arm represents a formidable challenge for an orthopaedic surgeon. We could not find any similar report in the literature dealing with this issue thus far. Read More
