Rehabilitation of atrophic mandible with implants. Strategy and case report of fracture complication

Rehabilitation through implant-supported prosthesis on atrophic jaws presents great deal of difficulty. Mandible fractures related to implants is not a common complication, however when it occurs, it represents serious damage. The aim of this paper was to report a clinical case of a 63-year-old patient with mandibular fracture after implant installation, treated through a buccal access and load-shearing plate system to stabilize the fractured bone and reduce the discomfort. The use of load shearing plate presented good results in this case, stabilizing the bone fracture, and helping with the repairing process, enabling subsequent rehabilitation of the patient, with a 3-year follow-up.

Double reverse traction repositor versus traction table for the treatment of intertrochanteric femur fracture: A comparative Study

Background The aim of this study was to compare the clinical results between double reverse traction repositor and traction table used for the treatment of unstable intertrochanteric femur fracture. Methods This retrospective study included 95 patients with AO/OTA 31- A2 and A3 proximal femur fracture, who underwent double reverse traction repositor or traction table facilitated Asian proximal femoral nail antirotation (PFNA-II) nailing. The demographics, duration of operation, blood loss, part loading time after surgery, the period of union of fracture, complication were assessed. Clinical and radiological outcomes were evaluated. Results There were no significant differences in respect to demographics and fracture characteristics. Duration of patient positioning and total operative time were significant longer in traction table group than that in double reverse traction repositor group(p<0.001). No differences were found intraoperative blood loss, part loading time after surgery, fracture healing time and Harris Hip Score between two groups. Conclusion When treating unstable intertrochanteric fractures, double reverse traction repositor is superior to tract table in respect to operative time and duration of patient position, despite an additional ipsilateral anterior superior iliac spine (ASIS)incision and drilling of ASIS and femur condyle.

Pathological Fracture of Femoral Neck Associated to Femoral Head Osteonecrosis: Case Report

Introduction: The osteonecrosis of femoral head is a progressive and devastating condition for the prognosis of the coxofemoral joint, with an increase in its prevalence and an etiology of multifactorial nature, and with compromise specially in young or middle age (20 to 40 years of age) patients [1-3]. The fractures associated to femoral head osteonecrosis are very rare, being the subchondral portion the site with a higher compromise, and the junction between the necrotic bone and the bone under remodeling process another site of potential fracture [4-7]. The management of this condition can vary from a conservative management to a surgical management with total hip arthroplasty, depending on patient’s clinic and the extension of his necrotic lesion. Discussion: This patient presents a sub-capital fracture of his femoral neck, associated to osteonecrosis of the femoral head. This patient was managed with decompression of the osteonecrosis nucleus plus bone graft and osteosynthesis with cannulate screws, in order to decrease bone hypertension and avoid femoral collapse. Conclusion: Although femoral neck fractures, as a complication from femoral head osteonecrosis are rare, in our patient such association can be found due to the worsening of his painful clinical features and the absence of a previous traumatic event, which allows discarding femoral osteonecrosis as a fracture complication.

Frequency of Prosthetic Complications Related to Implant-Borne Prosthesis in a Sleep Disorder Unit

Sleep bruxism and higher clench index have been associated with obstructive sleep apnea (OSA). However, there is no study that reports on the prosthetic complications in patients with OSA. Records of patients who had performed a sleep study to diagnose OSA were examined for the occurrence of prosthetic complications in implant-borne reconstructions. The primary outcome was the frequency of prosthetic complications. The secondary outcomes were anthropometric data, type of complication, type of prosthesis, type of retention, number of supporting implants, number of prosthetic units, and the presence of obstructive sleep apnea. Of the 172 patients, 67 had an implant-supported prosthesis, and all were included in the study. The mean age was 61 ± 10 years, and 36 were female. Thirty complications in 22 prostheses were identified in 16 patients. The complications were porcelain fracture (14 events), screw/implant fracture (8 events), screw loosening (3 events), and decementation (5 events). The follow-up time was 117 ± 90 months after placement of the prosthesis. The average time for complications to occur was 73 ± 65 months after the placement of the prosthesis. According to the apnea-hypopnea index (AHI), 49 patients had OSA. Thirteen of the 16 patients having a prosthetic complication also had OSA. The highest AHI and thus the severity of OSA was identified in patients with a fracture complication related to an implant, a screw, or a porcelain. The frequency of prosthetic complications has been higher in patients with obstructive sleep apnea.

Pulsative hematoma: A penile fracture complication

Background. Fracture of the penis is a direct blunt trauma of the erect or semi-erect penis. It can be treated by conservative or surgical means. Retrospective analyses of conservative penile fracture treatment reveal frequent immediate and later complications. Case report. We presented a 41- year-old patient with pulsative hematoma caused by an unusual fracture of the penis. Fracture had appeared 40 days before the admittance during a sexual intercourse. The patient was treated surgically. Conclusion. Pulsative hematoma (pulsative diverticulum) is a very rare, early complication of a conservatively treated penile fracture. Surgical treatment has an advantage over surgical one, which was confirmed by our case report.
