RESUMO

Tibial plateau fractures are often complex injuries that result from high-energy trauma affecting the articular congruity of the knee. Managing tibial plateau fractures can be challenging because of severe depression of the subchondral cancellous bone and concomitant cartilage injury. Bone substitutes are commonly used to fill such defects as part of the surgical treatment of tibial plateau fractures. We describe three cases of tibial plateau fractures managed with a synthetic bone substitute (b.Bone™, GreenBone ORTHO S.p.A Faenza, Italy) with a highly interconnected and porous 3D structure to mimic the hierarchical architecture and morphology of natural human bone.

RESUMO

PURPOSE: Reamer-irrigator-aspirator (RIA) is an innovative device that its indications have recently been expanded to the management of long bone infections. METHODS: In this narrative review, we summarise the most important studies in the field and we present the current open questions pertaining to the use of RIA in the management of osteomyelitis of long bones. RESULTS: The relevant literature is sparse and low quality. Nevertheless, the use of RIA for infected cases has yielded promising outcomes in specialised centres. Technical aspects that merit special attention in osteomyelitis of long bones are its inapplicability in small diameter long bones, the inadequate debridement of wide metaphyseal areas and the potential bleeding sequelae. The use of RIA in open fracture management to reduce infection risk has not gained acceptance. The antibiotic impregnated nails and rods constitute a complimentary strategy for the management of infections. CONCLUSIONS: The use of RIA for the management of long bone infections is an innovative and promising strategy. High quality studies are needed to shed light in its efficacy compared to conventional methods of management of osteomyelitis of long bones.

RESUMO

PURPOSE: Paediatric trauma is the leading cause of mortality in children. Paediatric trauma resuscitation is the first and foremost step towards a successful treatment and subsequent recovery. Significant advances have taken place in the last years in relation to this field of trauma care. METHODS: In this narrative review, we attempt to summarise the recent development in the concepts of fluid resuscitation, massive transfusion, permissive resuscitation, management of coagulopathy and use of tranexamic acid, literature pertaining to implementation of transfusion protocols in the paediatric population and education related to the paediatric trauma resuscitation. RESULTS/CONCLUSIONS: The current evidence although emerging is still sparse and high-quality studies are needed to shed more light on most of the above domains of resuscitation.

RESUMO

Intramedullary infection in long bones represents a complex clinical challenge, with an increasing incidence due to the increasing use of intramedullary fixation. We report a prospective case series using an intramedullary reaming device, the Reamer-Irrigator-Aspirator (RIA) system, in association with antibiotic cement rods for the treatment of lower limb long bone infections. A total of 24 such patients, 16 men and eight women, with a mean age of 44.5 years (17 to 75), 14 with femoral and 10 with tibial infection, were treated in a staged manner over a period of 2.5 years in a single referral centre. Of these, 21 patients had had previous surgery, usually for fixation of a fracture (seven had sustained an open fracture originally and one had undergone fasciotomies). According to the Cierny-Mader classification system, 18 patients were classified as type 1A, four as 3A (discharging sinus tract), one as type 4A and one as type 1B. Staphylococcus species were isolated in 20 patients (83.3%). Local antibiotic delivery was used in the form of impregnated cement rods in 23 patients. These were removed at a mean of 2.6 months (1 to 5). Pathogen-specific antibiotics were administered systemically for a mean of six weeks (3 to 18). At a mean follow-up of 21 months (8 to 36), 23 patients (96%) had no evidence of recurrent infection. One underwent a planned trans-tibial amputation two weeks post-operatively due to peripheral vascular disease and chronic recalcitrant osteomyelitis of the tibia and foot. The combination of RIA reaming, the administration of systemic pathogen-specific antibiotics and local delivery using impregnated cement rods proved to be a safe and efficient form of treatment in these patients.

RESUMO

We systematically reviewed the published literature on the complications of closing wedge high tibial osteotomy for the treatment of unicompartmental osteoarthritis of the knee. Publications were identified using the Cochrane Library, MEDLINE, EMBASE and CINAHL databases up to February 2012. We assessed randomised (RCTs), controlled group clinical (CCTs) trials, case series in publications associated with closing wedge osteotomy of the tibia in patients with osteoarthritis of the knee and finally a Cochrane review. Many of these trials included comparative studies (opening wedge versus closing wedge) and there was heterogeneity in the studies that prevented pooling of the results.

RESUMO

A systematic review of the literature was conducted to investigate data regarding femoral head fractures, particularly focusing on their management, complications and clinical results. Twenty-nine eligible articles, meeting prespecified inclusion criteria, reported on 453 femoral head fractures in 450 patients (mean age of 38.9 years with a mean follow-up of 55.6 months). 84.3% of patients had been victims of an automobile accident. The most widespread classification scheme used was that of Pipkin (65.4% of cases) whereas clinical results were evaluated mainly according to Thompson-Epstein criteria (63.3% of cases). Fracture-dislocations, in their majority, were managed with emergent closed reduction, followed by definite treatment (closed or open), aiming at anatomic restoration of both fracture and joint incongruity. Regarding Pipkin 1 subtype, fractured fragment excision seems to give better results compared to ORIF (p=0.07), while for the more challenging Pipkin 2 fractures the principles of anatomic reduction and stable fixation should be applied. Wound infection was encountered with a rate of 3.2% of surgical cases and sciatic nerve palsy complicated 3.95% of fracture-dislocations. Major late complications included avascular necrosis (11.9%), post-traumatic arthritis (20%) and heterotopic ossification (16.8%). Neither the trochanteric-flip nor the anterior approach seems to put in more danger the femoral head blood supply compared to the posterior one, with the former giving promising long-term functional results and lower incidence of major complication rates.

RESUMO

We reviewed the outcome of 28 patients who had been treated using the Aequalis fracture prosthesis for an acute fracture of the proximal humerus at a mean follow-up of 39.3 months (24 to 63). The mean age of the patients at the time of the fracture was 66.3 years (38 to 80). The mean Constant score was 68.2 (37 to 84) for the operated shoulder, which represented 89.5% of the mean score for the uninjured side (p < 0.001). The quality of the reconstruction as shown on the immediate post-operative radiographs was categorised into three types, anatomical, acceptable, and unacceptable, depending on the position of the tuberosities relative to the prosthetic head and the humeral shaft. Anatomical reconstruction was associated with a higher mean Constant score as well as higher mean values of anterior forward elevation, abduction and external rotation than the other types, but the differences were not statistically significant (p > 0.231). A total of 18 patients had active anterior elevation > or =150 degrees. Their mean active abduction and external rotation were 163.6 degrees and 31.3 degrees, respectively. In seven of the 28 patients, the mean active anterior elevation, abduction and external rotation were 130.7 degrees, 129.2 degrees and 22.8 degrees, respectively. In all, 12 patients were very satisfied with the results, 12 were satisfied, two were dissatisfied and two were disappointed; 26 reported no or only mild pain while only two had moderate pain. In five patients proximal migration of the humeral head was shown on the anteroposterior radiographs of the shoulder. No evidence of loosening was found in any prosthesis.

RESUMO

We performed a comprehensive systematic review of the literature to examine the role of hemiarthroplasty in the early management of fractures of the proximal humerus. In all, 16 studies dealing with 810 hemiarthroplasties in 808 patients with a mean age of 67.7 years (22 to 91) and a mean follow-up of 3.7 years (0.66 to 14) met the inclusion criteria. Most of the fractures were four-part fractures or fracture-dislocations. Several types of prosthesis were used. Early passive movement on the day after surgery and active movement after union of the tuberosities at about six weeks was described in most cases. The mean active anterior elevation was to 105.7 degrees (10 degrees to 180 degrees) and the mean abduction to 92.4 degrees (15 degrees to 170 degrees). The incidence of superficial and deep infection was 1.55% and 0.64%, respectively. Complications related to the fixation and healing of the tuberosities were observed in 86 of 771 cases (11.15%). The estimated incidence of heterotopic ossification was 8.8% and that of proximal migration of the humeral head 6.8%. The mean Constant score was 56.63 (11 to 98). At the final follow-up, no pain or only mild pain was experienced by most patients, but marked limitation of function persisted.

RESUMO

Vertebral haemangiomas are usually asymptomatic and discovered fortuitously during imaging. A small proportion may develop variable degrees of pain and neurological deficit. We prospectively studied six patients who underwent eight surgical procedures on 11 vertebral bodies. There were 11 balloon kyphoplasties, six lumbar and five thoracic. The mean follow-up was 22.3 months (12 to 36). The indications for operation were pain in four patients, severe back pain with Frankel grade C paraplegia from cord compression caused by soft-tissue extension from a thoracic vertebral haemangioma in one patient, and acute bleeding causing Frankel grade B paraplegia from an asymptomatic vascular haemangioma in one patient. In four patients the exhibited aggressive vascular features, and two showed lipomatous, non-aggressive, characteristics. One patient who underwent a unilateral balloon kyphoplasty developed a recurrence of symptoms from the non-treated side of the vertebral body which was managed by a further similar procedure. Balloon kyphoplasty was carried out successfully and safely in all patients; four became asymptomatic and two showed considerable improvement. Neurological recovery occurred in all cases but bleeding was greater than normal. To avoid recurrence, complete obliteration of the lesion with bone cement is indicated. For acute bleeding balloon kyphoplasty should be combined with emergency decompressive laminectomy. For intraspinal extension with serious neurological deficit, a combination of balloon kyphoplasty with intralesional alcohol injection is effective.
