Acta Med Okayama 2021 Apr;75(2):177-185

Department of Musculoskeletal Traumatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences.

This retrospective study sought to elucidate the incidence rates of roof impaction (RI) and marginal impaction (MI) and radiological and clinical outcomes of open reduction and internal fixation (ORIF) for RI and MI in geriatric acetabular fractures. The cases of 68 patients aged ≥ 65 years (mean 71 years) treated with ORIF were analyzed. MI was present in 12 fractures (67%) and an RI of the weight-bearing surface was present in 24 (46%) of the potential fracture types. Read More

Femoral Intercondylar Notch: Gross Anatomy and Histology of the Connective Tissue Lining of its Roof: A Pilot Study.

Surg Radiol Anat 2021 Apr 28. Epub 2021 Apr 28.

Department of FMT, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, India, 110029.

Purpose: We have consistently observed a connective tissue lining over the intercondylar notch's roof (CTLINR) during arthroscopic surgeries of the knee joint. As there is a strong association of the intercondylar fossa with the anterior cruciate ligament (ACL), we believe that this tissue must be having some role in the functioning of the ACL. The purpose of this pilot study was to investigate the anatomic characteristics of the CTLINR. Read More

Interbundle Impingement Pressure in Individualized and Nonindividualized Double-Bundle Anterior Cruciate Ligament Reconstruction: A Cadaveric Study.

Orthop J Sports Med 2021 Feb 2;9(2):2325967120958487. Epub 2021 Feb 2.

Department of Sports Medicine, Xiangya Hospital, Central South University, Changsha, China.

Background: Graft impingement is one of the main concerns in double-bundle anterior cruciate ligament reconstruction (DB-ACLR). Impingement between the anteromedial (AM) and posterolateral (PL) bundles has been postulated to cause graft deterioration or rerupture, but this has not been thoroughly investigated, and the interbundle impingement pressure (IIP) has not been well researched.

Purpose: To determine the IIP between the AM and PL bundles in the native anterior cruciate ligament (ACL) and in DB-ACLR with individualized and nonindividualized double-tunnel placement. Read More

Management of the posterior wall fracture in associated both column fractures of the acetabulum.

Eur J Orthop Surg Traumatol 2021 Jan 1. Epub 2021 Jan 1.

Department of Orthopaedic Surgery, Stanford University, 450 Broadway Street, Pavilion C, 4th Floor, Redwood City, CA, 94063-6342, USA.

Purpose: The primary aim of this study was to compare clinical outcomes in patients with associated both column (ABC) acetabular fractures with fracture of the posterior wall (PW), in which the PW underwent reduction and fragment-specific fixation versus those that were treated with column fixation alone. Secondary aims were to assess PW fracture incidence and morphology, as well as to compare radiographic outcomes including fracture healing and interval displacement of the PW in those that did and did not undergo fragment-specific fixation of the PW.

Methods: This was a retrospective series of ABC acetabular fractures treated at a single Level I trauma center. Read More

Orbitocranial Fibrous Dysplasia: Immediate Reconstruction with Titanium 3-dimensional Printing.

Plast Reconstr Surg Glob Open 2020 Sep 21;8(9):e3114. Epub 2020 Sep 21.

Advanced Materials Analysis Research Unit, Department of Metallurgical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok, Thailand.

We present the case of an 18-year-old man who was referred to our department with a suspected tumor in the right orbital region, which caused exophthalmos due to its pressure effect. Preoperative CT imaging revealed an expansile ground-glass appearance of bone mass, with sclerotic bone on the right frontal bone (right superior orbital wall). There was no orbital mass and no enlargement of the extraocular muscles and tendons; the retrobulbar fat and optic nerve appeared unremarkable. Read More

Outcome of Different Surgical Approaches in the Treatment of Class II Furcation Defects in Mandibular Molars: A Randomized Clinical Trial.

Int J Periodontics Restorative Dent 2020 Sep/Oct;40(5):693-701

The aim of this study was to investigate which factors play a major role in the healing of Class II mandibular furcation defects treated with different surgical techniques. Twenty-five systemically healthy subjects with periodontitis stage III grade B and Class II buccal mandibular furcation involvement received one of the following open flap debridement approaches: Group 1 (n = 10), no further treatment; Group 2 (n = 10), piezoelectric contouring of the furcation roof; Group 3 (n = 9), piezoelectric contouring of the furcation roof and bone grafting; Group 4 (n = 10), piezoelectric contouring of the furcation roof and bone grafting with coronally positioned flap. Clinical and radiologic variables-bleeding on probing, probing depth (PPD), vertical and horizontal bone level (CAL and PH), gingival recession, root trunk length, radicular separation, and furcation perimeter (FP)-were evaluated at baseline and 180 days and 1 year after surgery.

Outcomes of Total Hip Arthroplasty After Acetabular Open Reduction and Internal Fixation in the Elderly-Acute vs Delayed Total Hip Arthroplasty.

J Arthroplasty 2021 02 18;36(2):605-611. Epub 2020 Aug 18.

Division of Orthopaedic Surgery, The Ottawa Hospital, Ottawa, Ontario, Canada.

Background: Optimum management for the elderly acetabular fracture remains undefined. Open reduction and internal fixation (ORIF) in this population does not allow early weight-bearing and has an increased risk of failure. This study aimed to define outcomes of total hip arthroplasty (THA) in the setting of an acetabular fracture and compared delayed THA after acetabular ORIF (ORIF delayed THA) and acute fixation and THA (ORIF acute THA).

Is Surgical Site Infection (SSI) after skin surgery affected by home municipal versus non-municipal water supply?

J Plast Reconstr Aesthet Surg 2020 Nov 26;73(11):2049-2055. Epub 2020 Aug 26.

Auckland Regional Plastic & Reconstructive Surgery Unit, Private Bag 93311, Otahuhu, Auckland 1640, New Zealand; University of Auckland School of Medicine, Auckland, New Zealand. Electronic address:

Purpose: SSI represent one of the most common sources of morbidity and escalated healthcare costs in skin cancer management. It has been shown that exposing wounds to treated water does not increase SSIs, however a large proportion of Australasian patients reside in rural areas dependant on roof or bore collected water for their primary water supply, and no data exist regarding the association between tank water supply and SSI following skin surgery.

Methodology: A nine-month retrospective analysis of patients undergoing skin cancer surgery at the Auckland Regional Plastic Surgery Unit was performed. Read More

Blumensaat Line as a Prediction of Native Anterior Cruciate Ligament Length.

Orthop J Sports Med 2020 Aug 6;8(8):2325967120943185. Epub 2020 Aug 6.

Northwestern Medical Group, Lake Forest, Illinois, USA.

Background: Graft-tunnel mismatch (GTM) is a condition in which the anterior cruciate ligament (ACL) graft is either too long or too short. GTM is particularly problematic when bone-patellar tendon-bone grafts are used because of a potential compromise in fixation of the bone plug on the tibia.

Hypothesis: The Blumensaat line (BL), a radiographic landmark representing the roof of the intercondylar fossa, will accurately approximate the native ACL (nACL) length and may aid in the prevention of GTM. Read More
