Three-Dimensional Digital Surgical Planning and Rapid Prototyped Surgical Guides in Bernese Periacetabular Osteotomy.

Case Rep Orthop 2020 15;2020:8897066. Epub 2020 Jun 15.

Faculdade de Medicina da Universidade Federal de Juiz de Fora, Programa de Pós-Graduação em Saúde Coletiva, Av. Eugênio do Nascimento, s/n, Dom Bosco, Juiz de Fora, MG, Brazil.

Bernese periacetabular osteotomy (PAO) developed by Ganz is currently the treatment of choice for skeletally mature symptomatic patients with developmental dysplasia of the hip (DDH) without osteoarthritis. However, the steep learning curve and considerable number of severe complications lead surgeons to seek for alternatives to promote greater reproducibility and safety of this procedure. This is a report of a DDH case surgically treated with the aid of a digital three-dimensional (3D) planning and rapidly prototyped sterile ABS plastic osteotomy guide, developed in Brazil. Read More

Impact of Jiggling Exercise as Conservative Treatment for Hip Osteoarthritis: A Report of Two Cases.

Case Rep Orthop 2020 4;2020:2804193. Epub 2020 May 4.

Department of Orthopaedic Surgery, Kitasato University School of Medicine, 1-15-1 Kitasato, Minami-ku, Sagamihara, Kanagawa 252-0374, Japan.

Total hip arthroplasty has been recognized as a feasible treatment for hip osteoarthritis, especially in advanced and terminal stages, but whether it is the best treatment for patients who are younger, have comorbidities, and/or are likely to have low compliance to medical treatment is unknown. Jiggling exercise, which involves the continuous shaking of the foot and leg in small steps, has been reported to be the easiest and a less invasive exercise for patients with hip osteoarthritis. We herein report two patients who performed jiggling exercise as conservative treatment and had successful outcomes. Read More

Successful Treatment of a Massive Desmoplastic Fibroma of the Ilium without Surgery: A Case Report with Long-Term Follow-Up.

Case Rep Orthop 2020 20;2020:5380598. Epub 2020 Mar 20.

Department of Orthopedic Surgery, Chiba Cancer Center, 666-2 Nitonacho, Chuo-ku, Chiba 260-8717, Japan.

Desmoplastic fibroma of the bone (DFB) is a notably rare, lytic, locally aggressive but nonmetastatic, primary benign bone tumor in patients less than 30 years old. As the recommended primary treatment for DFB, wide resection is preferred to curettage from the perspective of recurrence but wide resection of DFB in the pelvis such as in the acetabulum could result in greater functional loss, suggesting the need for conservative treatments. However, there is no report on long-term follow-up following conservative treatment for DFB. Read More

Single-Stage Arthroscopic Anterior and Posterior Cruciate Ligament Repairs and Open Medial Collateral Ligament Repair for Acute Knee Dislocation.

Case Rep Orthop 2020 24;2020:7348201. Epub 2020 Feb 24.

Department of Sports Orthopedic Surgery, Kanto Rosai Hospital, 1-1 Kizukisumiyoshicho, Nakahara-ku, Kawasaki City, Kanagawa Prefecture, Japan.

Till date, there are no clear guidelines regarding the treatment of multiple ligament knee injuries. Ligament repair is advantageous as it preserves proprioception and does not involve grafting. Many studies have reported the use of open repair and reconstruction for multiple ligament knee injuries; however, reports on arthroscopic-combined single-stage anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) repairs are scarce.

Department of Orthopedics, Cedars Sinai Medical Center, Los Angeles, CA, USA.

Glomus tumors are rare benign tumors which commonly affect the hand but are seldom seen extradigitally. Less commonly seen is the glomangioma, a variant of benign glomus tumor, and even rarer is the glomangiosarcoma, a malignant variant. Determining malignancy can be difficult and an intermediate diagnosis, glomus tumor of uncertain malignant potential, has been proposed. Read More
