Cryopreserved Umbilical Cord Allograft for Root Coverage of Gingival Recession Defects: A Case Series.

Cryopreserved Umbilical Cord Allograft for Root Coverage of Gingival Recession Defects: A Case Series. Int J Periodontics Restorative Dent. 2019 May/Jun;39(3):391-397 Authors: Ross B, Ross SB Abstract Gingival recession is a component of periodontal disease that leads to exposure of the root surface, root hypersensitivity, and esthetic concerns. Treatment of these cases is typically performed with autologous grafts harvested from the palate. However, this is associated with a second surgical site that increases surgical time and patient morbidity. A potential alternative is the use of cryopreserved umbilical-cord allografts, which are known to contain anti-inflammatory properties and have been used clinically by numerous medical specialties. In this observational series, three patients with gingival recession (average gingival margin [GM]: 3.16 ± 1.13 mm) showing Miller Class I to III gingival recession were treated with cryopreserved umbilical-cord allografts. Ten days after the root coverage procedure, all patients reported no pain or discomfort, and only normal, mild swelling was observed. After 3 months, the gingival tissue was completely healed and matched the color and texture of the patient's surrounding tissue. At 1 year after surgery, patients exhibited 100% root coverage at 33 of 38 treated sites (average GM: 0.18 ± 0.51 mm), as well as an increase in band of attached gingiva. The encouraging safety and effectiveness of this report...

Allograft reconstruction of chronic peroneal tendon tears is a safe and effective option to help restore patient function and limit pain. Both the author’s experience, along with cadaveric and clinical studies, have shown that this technique can restore function and stability. The authors provide step-by-step instruction of their preferred allograft reconstruction technique for chronic peroneal attritional injuries, while limiting the comorbidities that may be seen with autograft reconstruction. Level of Evidence: Level IV—review article, expert opinion, operative technique.

More than a dozen surgical techniques have been described for management of avascular necrosis or traumatic loss of large portions of the talus. The smaller the area of necrosis, the better the outcomes. Procedures to induce revascularization (core decompression/drilling, vascularized bone grafts) have been reported with variable success. Patients with avascular necrosis of large portions of the talus present unique treatment difficulties. These techniques largely focus on pantalar or tibiotalar-calcaneal arthrodesis with large bone blocks. These surgeries eliminate motion, lead to high levels of patient dissatisfaction, a...

Authors: Shi Y, Chen L, Xu Y, Zhang X, Ju X, Hu X, Ao Y, Wang J Abstract Acetabular labral tears are common in patients presenting with hip or groin pain. When the labrum is irreparable, labral reconstruction procedures are warranted. A circumferentially intact labrum is essential for joint health, whereas labral deficiency may predispose hip joints to osteoarthritis (OA). We aimed to determine whether labral reconstruction provides a benefit in terms of reduced OA development compared with labral resection. We performed labral reconstructions, labral resections, and sham operations in a porcine model. We assessed ...

Conclusion. Preoperative uNTx was greater in patients with successful ACDF fusion compared with patients with pseudarthrosis at 6 months and 1 year. A negative correlation was found between preoperative uNTx and motion on dynamic imaging. These results suggest that uNTx could serve to identify patients at risk for pseudarthrosis after ACDF.

DiscussionWhen used for clavicular reconstruction, the induced membrane technique is effective and associated with a low complication rate. The induced membrane technique therefore deserves to be viewed as an alternative to other methods.Level of evidenceIV, retrospective observational study.

Hey forum, weigh-in on this: 83 y/o F with new L5 compression fracture from 2 months back (30% superior endplate compression) with fracture lines that extend into the bilateral pedicles, L>R. I want to fix this thing, but she also has history of L4-S1 posterior fusion with bone graft (fusion done in 1975) going right over the pedicle shadow. Hard to make out any definable anatomy needed on left, but I do see my landmarks on right. Does anyone have experience trying to fix fractures in... Compression fx/vertebroplasty question

We present a case of an 18-year-old with a 2-year history of buttock pain who failed extensive treatment for a perceived hamstring strain. Upon evaluation, he was diagnosed with an ischial tuberosity nonunion avulsion fracture. The patient underwent bone grafting via an ultrasound guided leukocyte rich platelet-rich plasma injection followed by the use of a bone stimulator to enhance the bone healing. At 3 months, he was asymptomatic and had radiographic evidence of excellent bone healing. He remained asymptomatic at 1 year and had resumed full activities. This case report is the first in the literature to describe the tre...

Abstract A 47-year-old male with a remote renal transplant due to pediatric glomerulonephritis on oral anticoagulation for symptomatic deep venous thrombosis and pulmonary emboli presented with sudden hip and groin pain. The patient was found to have a spinal epidural hematoma, underwent reversal of anticoagulation, and subsequently developed worsening renal function. Imaging revealed occlusive iliocaval venous thrombosis with extension to the renal allograft. Given risk of epidural hematoma expansion, the patient was deemed high risk for thrombolysis. The AngioVac system was used for single session thrombus remov...

Abstract Adult flatfoot is a common pathology characterized by multiplanar deformity involving hindfoot, midfoot, and forefoot. Various surgical techniques have been described for the treatment but may not adequately correct the fixed forefoot varus component. Residual forefoot supination can be addressed by a plantar flexing opening wedge osteotomy of the medial cuneiform, also known as a Cotton osteotomy. Thus, the aims of this study were to compare clinical, radiological, and functional outcome after Cotton osteotomy, in patients treated with bone allograft or metallic implant. Consequently, 36 patients treated...
