Anterior inferior iliac spine avulsion fracture: a series of 5 cases.

AbstractAvulsion fractures of the pelvic apophyses rarely occur in adolescent athletes in the course of sudden strong contraction of muscle attached to growth cartilage. This injury may usually be misdiagnosed for tendon or muscle strain. Patients history, physical examination, and radiologic studies are important for diagnosis. The literature includes only a few case reports but no case series as yet. The aim of this study was to present the results of 5 cases of anterior inferior iliac spine (AIIS) avulsion fractures treated conservatively.The study included 5 patients (4 male, 1 female, mean age 13.6 years) who underwent conservative treatment for AIIS avulsion fractures and had an adequate follow-up. All patients were admitted to the emergency department and misdiagnosed as muscle strain. Three of them were football player, 1 skier, and 1 fighter.Each patient was treated with immobilization and nonsteroidal anti-inflammatory drugs. At follow-up, all patients showed relief from their pain and mechanical symptoms and regained full range of motion and returned to their previous levels of activity.Diagnosis requires careful attention to the physical examination and imaging. In this series, all pelvic avulsion fractures (100%) were managed successfully with a conservative approach. Good results and return to previous levels of activity can be achieved with conservative treatment.

Closed reduction and intramedullary pinning in the treatment of adult radial neck fractures: a case report

Closed reduction and intramedullary pinning (CIMP) in pediatric radial neck fractureswas first reported by Metaizeau in 1980 andsatisfactory results have been published several times. The current literature did not encounter any publication related to the implementation of Metaizeau method to adult patients. We applied Metaizeau technique to an adult radial neck fracture and we have achieved satisfactory results. As this case report is single case of this method applied to an adult, we decided to present this case.

Unusual Localization of a Primary Hydatid Cyst: Scaphoid Bone

AbstractBecause hydatidosis of the bone (echinococcus infection) is a rare parasitic infection, its diagnosis and treatment poses great difficulties. Radiologic imaging findings are generally helpful to make the diagnosis. But occurrence of disease in atypical places and lack of specific radiological findings may complicate differential diagnosis. Nevertheless, familiarity with imaging findings in patients living at endemic areas provides advantages for diagnosis and treatment.We present a cyst hydatic case in scaphoid bone which has been reported in the literature only once previously.

Isolated posterior malleolus fracture: a rare injury mechanism

Sprain of the ankle is undoubtedly a common injury during athletic activity, and the sprain can be also associated with fracture of the ankle. Isolated posterior malleolus fracture is a very rare condition, which is usually missed. Here, we are presenting a 37 years old female patient, who suffered injury secondary pressing on brake pedal during collision in a traffic accident. Clinical evaluation is based on Ottawa Ankle Rules and a fracture is diagnosed; patient is started on daily activities at postoperative Week 8. This study aims to emphasize that Ottawa Ankle Rules are usually efficient for evaluating fractures of ankle, but clinicians should always make a detailed physical examination.

Learning Curve for Surgical Treatment of Acetabular Fractures: A Retrospective Clinical Study of a Practical and Theoretical Training Course

Background Surgical treatment of acetabular fracture and the anatomic reconstruction of the hip joint are difficult to achieve due to the complex pelvic anatomy, and surgical training requires a prolonged and steep learning curve. The aim of this study was to evaluate the effects of an applied training course, including cadaveric dissection, for the surgical treatment of acetabular fractures. Material/Methods This retrospective study included 35 patients who underwent surgical treatment for acetabulum fractures between 2012–2016. Patients were divided into three groups during two training courses, for the first two years and second two years. The surgical treatment was performed through single or combined standard approaches, according to the fracture pattern. The radiological outcome was evaluated using Matta’s criteria to grade postoperative reduction and final radiological outcome and the restoration of the hip joint center (HJC). The clinical outcome was evaluated using the modified the Merle d’Aubigné-Postel (DAP) hip score. Results Both post-course groups had statistically better functional and radiological outcomes compared with the pre-course group. Depending on the learning curve, the mean duration of surgery decreased from 153 minutes to 82.3 minutes. Although there was no statistical difference between groups in the vertical shift of the HJC, there was a statistically significant in the amount of horizontal shift of the HJC in the second two years of training, compared with the other groups. Conclusions Functional and radiological outcome of surgical treatment of acetabular fracture may be improved with increased training, depending on the learning curve.

The Optimal Placement of Sutures in All-inside Repair of Meniscocapsular Separation.

Background: The aim of this study was to show the effects on the meniscus of repair applied from the femoral, the femoral-tibial and the tibial surfaces. Methods: In the treatment of meniscocapsular separation, although the accepted gold standard technique in the past was the inside-out suture technique, the current treatment method is all-inside repair methods. The all-inside techniques include the hook method and applications with a meniscus suture device. The hook method is difficult with a steep learning curve. In meniscus repair applied with the all-inside meniscus devices, the application of the suture can change the anatomic structure and position of the meniscus. Results: The suturing method applied from the tibial section of the meniscus does not disrupt the anatomic position of the meniscus in meniscocapsular separation. Thus, the optimum conditions are provided for restoration of the functions of the meniscus. Conclusion: The optimal repair in meniscocapsular separations can be considered to be that made with sutures from the tibial section of the meniscus. This technique may be helpful in obtaining better clinical results.

Dislocation of a revision total knee arthroplasty: Rare but serious complication

Dislocation of revision total knee arthroplasty is a very rare, serious and difficult complication. Incidence of significant instability and dislocation following primary TKA ranged from 1% to 2% in the past ten years. This incidence has been lowered to 0.15% to 0.5% with the development of modern surgical techniques and posterior stabilized implants. It is very few reports have been published but it is not usually described in textbooks. A 72-year-old man underwent primary total knee arthroplasty for osteoarthritis on the left side at a private hospital 5 years ago. He had aseptic loosening and the revision was performed. He was referred with a painful locked left knee without any history of trauma (5 months post revision surgery). On clinical examination the left knee was deformity and painful and locked in 40 degree flexion (A). His radiographs taken. Radiographs showed the left knee in flexion and a posterior dislocation of the knee (B). A lower extremity CT angiography showed intact vascular structures. The patient was taken to the operation theatre for exploration and if necessary, revision. We attempted closed reduction of the dislocated knee but this was unsuccessful. Paramedian arthrotomy was performed via the previous longitudinal incision, and the knee was exposed. The mobile components were removed and replaced with a large-size tibial insert (C). The patient was doing well on his 3-month and 1-year followup, ambulating with no assistive devices with good range of motion and no further instability and complications (D).

A rare case of extensive diffuse nonpigmented villonodular synovitis as a cause of total knee arthroplasty failure.

INTRODUCTION Nonpigmented villonodular synovitis (non-PVNS) is a benign proliferative disease involving the synovium. It is a rare condition that is little recognized. Non-PVNS has been reported as a cause of total knee replacement failure. PRESENTATION OF CASE We report a case of extensive diffuse non-PVNS in a patient with tibial component loosening after total knee replacement and review the related literature. DISCUSSION It is reported that pigmented villonodular synovitis (PVNS) occurs less frequently than non-PVNS after knee replacement. However, there are many more case reports of PVNS than non-PVNS after knee arthroplasty in the English-language literature. CONCLUSION Previously, there were no reported cases of extensive diffuse non-PVNS after total knee arthroplasty (TKA). This case study highlights an unusual case of non-PVNS as a cause of TKA failure. We propose that non-PVNS should be considered as a differential diagnosis in patients after TKA who present with recurrent pain and effusion/hemarthrosis of the knee, and that it is one of the causes of implant loosening after TKA.

Can Achilles tendon be used as a new distal landmark for coronal tibial component alignment in total knee replacement surgery? An observational MRI study

Background In total knee arthroplasty, it is better to use more than one reference point for correct alignment of the components. By measuring the distances of Achilles tendon (AT) and other conventional landmarks from the mechanical axis in magnetic resonance imaging (MRI) of the ankle, we aimed to demonstrate that, as a novel landmark which can help for correct alignment in the coronal plane, AT is a better option than other landmarks. Materials and methods This retrospective study was done on 53 ankle MRIs that met the criteria for inclusion to the study among 158 ankle MRIs. After identification of the mechanical axis, the distances of distal landmarks, which were extensor hallucis longus tendon (EHLT), tibialis anterior tendon (TAT), dorsalis pedis artery (DPA), AT, extensor digitorum longus tendon (EDLT), and malleoli, were measured from the mechanical axis and were statistically evaluated. Results In proximal measurements, the distances of the landmarks to the mechanical axis (on average) were AT, 2.64±1.62 mm lateral; EHLT, 3.89±2.45 mm medial; DPA, 4.69±2.39 mm medial; TAT, 8.24±3.60 mm medial; and EDLT, 14.2±4.14 mm lateral (P<0.001). In distal measurements, the distances of the landmarks to the mechanical axis (on average) were AT, 1.99±1.24 mm medial; EHLT, 4.27±2.49 mm medial; DPA, 4.79±2.10 mm medial; TAT, 12.9±4.07 mm medial; and EDLT, 12.18±4.17 mm lateral (P<0.001). Conclusion In this study, the mechanical axis line, which is the center of talus, passes through the AT. Our MRI investigations showed that the AT, EHLT, DPA, and malleolar center (3–5 mm medial) may help in correct alignment.

Is there a relationship between fracture healing and mean platelet volume

Objectives Platelet volume has been defined to be a marker that shows thrombocyte activation and function and it is measured as mean platelet volume (MPV). MPV shows the mean volume of circulating thrombocytes and it is one of the routine parameters in complete blood count. Increased thrombocyte volume is associated with thrombocyte activation. Patients and methods This study included 76 patients who were operated on due to fractures of long tubular bones. Patients who had union without any additional interventions were defined as group I, and patients who needed additional interventions due to nonunion or inadequate union were defined as group II. The control group included healthy volunteers who did not have a fracture. Hematologic test values of the patients that were obtained at admission to emergency ward were recorded. Results The groups were not statistically different in terms of age, sex, and the affected extremity. There were significant differences between group I and group II in terms of mean erythrocyte sedimentation rate, C-reactive protein, and MPV values (P<0.001), but there were no significant differences between group I and the control group. There was also no statistically significant difference among groups in terms of hematologic and biochemical variables. Conclusion In our study, fractures in patients who had lower MPV values than controls during the inflammation process healed without any problem, but fractures in patients with high MPV values more frequently needed additional surgical interventions.
