These fractures are often associated to chest trauma, other skeletal fractures or polytrauma. A “floating hip” injury is rare but a surgical challenging. Each case needs to be planned and addressed. We present a case of floating hip injury in a male patient, treated successfully with ORIF, followed by an uneventful postoperative period.

Nonvascularised autologous bone grafts have been used to fill the necrotic area and prevent the collapse of the femoral head. Harvesting and use of autologous femoral neck bone graft, minimizing the donor site complications and favoring the bone regeneration after core decompression. Methods: 17 patients in early stage of the femoral head osteonecrosis were operated, 12 males and 5 females with mean age of 45.3 years old. Were treated with core decompression and autograft harvested from the femoral neck. All the patients were evaluated with an MRI preoperatively, and at the follow up with X-rays of the hip and functional clinical scores. Results: We didn't observe any complications both at the donor site and the hip at any stage of the follow up. All the patients returned to previous everyday activities, free of pain. There was a significant improvement regarding the functional scores. Conclusion: We present the surgical technique of using femoral neck bone autograft for the treatment of the femoral head osteonecrosis. The technique is simply and sufficient in most early and midterm cases adding an advantage to the minimal invasing and join preserving technique of core decompression.

$Research paper thumbnail of Double lag-screw compression for optimal fixation of intertrochanteric fractures with large fragment gap: A technical note$

Anatomic fracture reduction and proper implant positioning are vital to attaining a favorable long-term surgical outcome. Appropriate intraoperative fracture compression augments stability and invigorates healing. The amount of compression permitted by cephalomedullary nails cannot always adequately reduce large fragment gaps. This paper presents a novel technical trick of double compression of the fracture site, in order to achieve the essential extra compression and reduction when required, thus decreasing the risk of postoperative implant cutout. The technique was used in 14 out of 277 peritrochanteric fractures treated with cephalomedullary nailing in our trauma center for 12 months, with satisfactory outcomes regarding both fracture site union and postoperative functional capacity.

Our patients were enrolled in three different groups, one comparing short-metaphyseal arthroplasties group and two high functional control groups. The first control group of resurfacing arthroplasties and a second of big femoral head arthroplasties. Each patient experienced a clinical examination and evaluated with Harris Hip Score, WOMAC, Sf-36, UCLA activity score, antero-posterior and lateral hip radiographies and were followed as outpatients for two years. At the last follow up all the patients perform a gait and static balance analysis. Statistical analysis have not revealed a significant difference between the three comparative groups regarding their demographic data nor a significant difference at the preoperative and the postoperative scores of each group. The radiographic evaluation revealed no differences and no complications. No one presented with cup or femoral loosening and no heterotopic ossification was observed. Also the comparing data of the three groups at the final 2 years postoperative control did not reveal any significant difference regarding their clinical scores and gait analysis results. The overall outcome of all three groups was similar and all the patients satisfied. We arrive at the conclusion that high functional resurfacing and big femoral head arthroplasties, present similar gait characteristics and functional outcome to the bone and soft preserving short-metaphyseal hip arthroplasties.

The new cephalomedullary nail InterTAN permits intraoperative linear compression and prevents the excessive neck sliding, control shortening and varus collapse of the neck, minimizing the risk of malunion or nonunion of the fracture. The aim of this study is to determine the clinical and functional outcomes of unstable peritrochanteric fractures treatment with the use of the InterTAN. Methods and Results: 126 consecutive unstable peritrochanteric fractures treated with an antegrade trochanteric nail InterTAN introduced to the study. The patients studied clinically and radiologically with the Harris Hip Score, Visual Analog Scale score and standard two view x-rays. Have been calculated intraoperatively and postoperatively at every follow up meeting the Tip Apex

Materials and methods We prospectively studied 158 TKA patients from 2014 to 2018. The patients were randomly assigned into three groups. Group A (46 patients) was administered intravenous and intra-articular TXA and RIV postoperatively; group B (58 patients) was administered TXA as in group A and LMWH postoperatively; and group C (54 patients) was administered saline as in group A and RIV postoperatively. We evaluated blood loss, transfusion requirements and hemorrhagic complications. Results Hct and Hb values significantly decreased in group C compared to groups A and B, without any difference between groups A and B. Suction drain blood volume output was significantly higher in group C compared to group A and B, without any difference between group A and B. Hemorrhagic complications were more common in group C. No patient experienced clinical findings of VTE. Conclusion Combined intravenous and intra-articular administration of TXA is safe and effective in TKA, with fewer hemorrhagic complications compared to placebo. Thromboprophylaxis with RIV and LMWH is similar.

The majority of hip surgeons allow patients to return to low-impact activities, but significant caution is advised to taking part in high-impact activities. The purpose of this study is to compare and evaluate the post-operative return to daily living habits and sport activities following short-metaphyseal hip and high functional total hip arthroplasties (resurfacing and big femoral head arthroplasties). Material and methods In a study design, 48 patients (55 hips) were enrolled in three different comparative groups, one with the short-metaphyseal arthroplasties, a second with high functional resurfacing arthroplasties and a third of big femoral head arthroplasties. Each patient experienced a clinical examination and evaluated with Harris Hip Score, WOMAC, Sf-36, UCLA activity score, satisfaction VAS, anteroposterior and lateral X-rays of the hip and were followed in an outpatient setting for 2 years. Results Statistical analysis revealed no notable differences between the three groups regarding their demographic data however significant differences have been found between preoperative and postoperative clinical scores of each group. Also, we fail to reveal any significant differences when comparing data of all three groups at the final 2 years postoperative control regarding their clinical scores. The overall outcome of all three groups was similar, all the patients were satisfied and returned to previous level of sport activities. Conclusion Short metaphyseal hip arthroplasties in young patients intending to return to previous and even high impact sport activities, similar to high functional resurfacing, big femoral head arthroplasties. Short stems with hard on hard bearing surfaces might become an alternative to standard stems and hip resurfacing.

To eliminate donor site morbidity and limited availability of autografts, porous tantalum was used. Eighteen patients who underwent subtalar joint distraction arthrodesis by means of trabecular metal augment were reviewed retrospectively. The results were evaluated clinically, with the American Orthopaedic Foot & Ankle Society (AOFAS) score and the visual analog scale (VAS) for pain, and were assessed radiologically. The mean follow-up period was 18 months. Computed tomography showed sound fusion. There was a marked increase in AOFAS scores and a decrease in VAS scores. Arthrodesis was achieved in all cases with no major postoperative complications. Radiographically, there was a marked increase in all measured parameters (talocalcaneal angle, talocalcaneal height, talar declination angle), and the intraoperatively achieved correction was maintained at the last follow-up visit. Our data suggest that porous tantalum may be used as a structural graft option for subtalar arthrodesis. Level IV, retrospective case series.
