Traumatic absence of the entire radial shaft in children has not been reported though there are a few reports of adult cases. We report a 5-year-old boy with traumatic absence of the entire right radial shaft. The Define's reconstruction procedure was chosen to localize the surgery only to the distal forearm and avoid further additional damage to the forearm muscles. The child's forearm was successfully reconstructed by the authors' modified Define's procedure, which was followed until his maturity. Hand function was well maintained...

Catastrophic failure of stemmed components in arthroplasty is an uncommon but a serious complication. Stem fractures and techniques for addressing these have been described following hip arthroplasty but much less so following total knee arthroplasty (TKA). We review three cases of catastrophic failure of the stem in rotating hinge revision TKA prostheses. We discuss the possible mechanism of failure and review the current literature addressing this topic. Metaphyseal support needs to be optimized in order to minimize load transfer to the stem and to the junction (and the risk of fracture) if a modular component is used...

Unsintered hydroxyapatite (u-HA) and poly-L-lactide (PLLA) composites (u-HA/PLLA) are osteoconductive and biodegradable. Screw (Super-Fixsorb MX30) and plate (Super-Fixsorb MX40 Mesh) systems made of u-HA/PLLA are typically used in small bones in maxillofacial surgeries. After the resection of bone tumors in larger bones, reconstructions with β-tricalcium phosphate (β-TCP) implants of strong compression resistance have been reported. After a resection, when the cavity is hemispheric- or concave-shaped, stabilization of the implanted β-TCP block is necessary...

Ju-Eun Kim, Dae-Jung Choi
Lumbar spine fusion has been widely accepted as a treatment for various spinal pathologies, including the degenerative spinal diseases. Transforaminal interbody fusion (TLIF) using minimally invasive surgery (MIS-TLIF) is well-known for reducing muscle damage. However, the need to use a tubular retractor during MIS-TLIF may contribute to some limitations of instrument handling, and a great deal of difficulty in confirming contralateral decompression and accurate endplate preparation. Several studies in spinal surgery have reported the use of the unilateral biportal endoscopic spinal surgery (technique for decompression or discectomy)...

Background: Leukocyte-poor platelet-rich plasma (LP-PRP) from peripheral blood is currently used as a concentrated source of growth factors to stimulate repair at sites of soft tissue injury. Fibroblasts are primary mediators of wound healing. Thus, we aimed to assess the positive effect of LP-PRP on human fibroblast proliferation in vitro . Methods: LP-PRP was prepared from 49 donors. The fibroblasts were seeded, and at 24 hours after seeding, 1 × 107 /10 µL LP-PRP was added once to each well...

Seungbum Koo, Sangho Chun, Kyoung Min Lee, Byung Chae Cho, Young-Jun Koo, Dong-Wan Kang, Moon Seok Park
Background: Although pedobarographic measurement is increasingly used for clinical and research purposes, relatively few published studies have investigated normative data. This study examined pedobarographic findings in young healthy adults with regard to sex-related differences and correlations among measurement indices. Methods: Twenty young healthy adults (mean age, 22.4 years; standard deviation, 1.2 years; and 10 males and 10 females) were included. Weight bearing anteroposterior (AP) and lateral foot radiographs were taken, and dynamic pedobarographic data during treadmill walking and maximum ankle dorsiflexion were obtained...

Background: Intervertebral disc herniations lead to subsequent compromise of the nerve root. The root can either have a mere contact with the disc material or be pushed aside or compressed. This was earlier graded by Pfirrmann and colleagues. We intend to revalidate this grading system by performing a reliability analysis among orthopaedic residents. Methods: Fifty axial cut magnetic resonance (MR) images of the affected lumbar disc level that belonged to different patients (age, 37...

Bogun Suh, Jaehyung Eoh, Jihoon Shin
Background: Longus colli calcific tendinitis (LCCT) exhibits characteristic clinical features; thus, misidentification can be avoided once it is learned. There is a lack of reports on this disease. In this study, we analyzed the imaging and clinical features of LCCT in 10 patients. Methods: We retrospectively reviewed the radiolographic findings, laboratory data and clinical features of 10 patients diagnosed with LCCT between January 2015 and June 2017. All patients were treated with medical treatment consisting of intravenous methylprednisolone 125 mg twice and oral nonsteroidal anti-inflammatory drug administration...

#13
Choong-Young Kim, Sang-Min Lee, Seong-An Lim, Yong-Soo Choi
Background: Weakness of cervical extensor muscles causes loss of cervical lordosis, which could also cause neck pain. The aim of this study was to investigate the impact of fat infiltration in cervical extensor muscles on cervical lordosis and neck pain. Methods: Fifty-six patients who suffered from neck pain were included in this study. Fat infiltration in cervical extensor muscles was measured at each level of C2-3 and C6-7 using axial magnetic resonance imaging...

#15
Dhong Won Lee, Cheol Hynn Yeom, Du Han Kim, Tae Min Kim, Jin Goo Kim
Background: The present study aimed to evaluate the prevalence of patellofemoral osteoarthritis (PFOA) and identify the factors that affect PFOA development after single-bundle anterior cruciate ligament (ACL) reconstruction with hamstring autograft. We hypothesized that detecting these factors could be helpful in establishment of a rehabilitation strategy to focus on the modifiable factors. Methods: Of the 324 patients who underwent primary ACL reconstruction between January 2010 and June 2013, 92 patients who were available for follow-up for a minimum of 36 months after the surgery and underwent second-look arthroscopy were enrolled...

Gerrard Gan, Yee Hong Teo, Ernest Beng Kee Kwek
Background: Periprosthetic fractures around a total knee replacement (TKR) can be complex and difficult to manage, requiring the surgical expertise of the trauma and arthroplasty surgeon. There are a number of treatment modalities available, each with their own merits and limitations. As data on tumor prosthesis revision in periprosthetic fractures is sparse, this study aims to evaluate the results of revision using a tumor prosthesis and compare them with those of fixation using a locking plate in periprosthetic fractures after TKR...

Ju-Kwon Park, Jong-Keun Seon, Kyu-Jin Cho, Nam-Hoon Lee, Eun-Kyoo Song
Background: Achieving neutral limb alignment during total knee arthroplasty (TKA) has been considered an important determinant in the long-term prosthesis survival. The purpose of this study was to evaluate the association between the immediate postoperative mechanical alignment of the lower limb and the rate of revision TKA by comparing an acceptable mechanical axis group (within ± 3° from neutral alignment) and an outlier group (> 3° deviation from neutral alignment). Methods: Between 2000 and 2006, clinical and radiographic data of 334 primary TKAs were retrospectively reviewed to determine the 10-year Kaplan-Meier survival rate...

Background: Bone mineral density (BMD) is the indicator of bone quality in at-risk individuals. Along with the fracture risk assessment tool (FRAX), a quick assessment of BMD from routine radiographs may be useful in the case of lacking X-ray absorptiometry data. This study aimed to investigate the correlation of cortical thickness index (CTI) and canal flare index (CFI) with BMD and FRAX and to evaluate their ability to predict femoral neck BMD (nBMD) and FRAX in the general elderly population...
