Semilunate and perilunate dislocation is an injury that mostly occurs when the subject is exposed to a high-energy trauma. Considered severe, it compromises the stability and function of the wrist. ...The case presented is that of a 50-year-old male patient who after having a motorcycle accident arrived at the ER with neurovascular affectation, swelling, deformity and a considerable decrease of the wrist joint movement. He was also referring severe pain. A Henry (Volar) intervention was done with the help of external fixation of the lunate, followed by K-wire fixation, once a prior closed reduction was unsuccessfully attempted. The scaphoid was connected to the semilunate, and then the latter with the capitate. Ligament reconstruction followed, and stability was clinically confirmed with an X-ray. Although improvement of symptomatology was observed during the follow-up analysis, motion of the wrist remained limited. Even with the best treatment, in terms of functionality, this type of injury presents a poor prognosis.
There are different types of infection caused by Mycobacterium tuberculosis, the pulmonary variety is the most common of them; infection of the bone secondary to joint replacement, is usually caused ...by a previous lung infection that has been disseminated. However primary bone infection is very rare and little reported, which makes information on the matter very scarce. A female patient is presented with a history of congenital hip dysplasia, who underwent multiple surgical interventions, including total hip arthroplasty (THA), afterwards she presented a fistula and persistent serous exudate; a biopsy was performed where acid-fast bacilli were detected. The delay in the diagnosis of osteoarticular tuberculosis (OATB) can lead to negative consequences, affecting the quality of life of the patient. Conventional diagnostic methods may be insufficient for the diagnosis of OATB.
The tibiofibular syndesmosis provides stability to the ankle mortise. The ankle syndesmosis is compromised in all Weber C type injuries. The radiographic method described by Merle DAubigné considers ...the bony relationships as a measure of syndesmotic widening. We sought to investigate whether the patients with a C type ankle fracture treated with ORIF and placement of a transyndesmal screw have an increment of the tibiofibular space and decrease of the tibiofibular overlap after the transyndesmal screw is removed. Our sample included 52 patients with Weber C ankle fractures treated by ORIF and transyndesmal screw at a level II trauma center. We measured the tibiofibular clear space and tibiofibular overlap in each phase of the treatment. The transyndesmal screw was removed at day 55.56 (± 21.83). We found an increase of the tibiofibular overlap of 0.20 mm (± 2.29, p = 0.532); and 0.21 mm (± 0.97, p = 0.146) in the tibiofibular clear space. The changes of 2.38% in the tibiofibular overlap and 5.29% in the tibiofibular clear space between the postoperative and post-removal periods were not statistically significant. After removal of the syndesmal screw, there is a slight radiographic broadening of the syndesmosis; however, it is small and statistically not significant.
A 16-year-old female patient showed up at the orthopaedics unit complaining of intolerable pain on her left hip. While being questioned and her clinical history written down, she shared that as part ...of her daily exercise routine, she ran 10 miles (16 km) daily at a speed of 9.5–10.5 mph (15–17 km/hour). MRI was consequently ordered, confirming the presence of a stress fracture. Therefore, immediate suspension of physical activity was indicated, followed by the prescription of crutches as well as restricted weight bearing. Gradually, she recovered complete functionality and approximately a month after she had entirely healed. While on a skiing trip, again she abruptly developed an acute pain on her right hip. Another MRI was ordered; its result confirmed a new stress fracture. Her previous treatment has proved so successful, a conservative approach was once again prescribed for her, showing optimum results 6 months later.
•The poor blood supply of the astragalus increases the risk of avascular necrosis.•The astragalus is composed mainly of cartilage, which reduces the risk of fracture.•It is important to keep this ...fracture in mind in injuries that could compromise the astragalus.•The physician needs to know the differential diagnoses to get the right diagnosis nd to administer the correct treatment.
The fracture of the astragalus is an unusual bone fracture (Ladero and Concejero, 2004) and is even more unusual in pediatric patients. The astragalus is a bone surrounded by cartilage and other structures making it difficult to appreciate on an X-ray which can lead to misdiagnosis (Ladero and Concejero, 2004; Inal and Inal, 2014) and could lead to not applying the right treatment and risk avascular necrosis or other sequelae.
3-year-old male with foot pain and edema+++, unable to walk or stand up since a fall 2 days before, had a doubtful diagnosis after an x-ray showed no apparent bone injury. A CT scan confirmed astragulus fracture; it was then treated adequately, thus avoiding complications that could have occurred had the fracture not been diagnosed and treated correctly.
The limb was immobilized with a suropodalic cast for 5 weeks. No surgery was performed because of the patient's age and because the fracture was not displaced (Hawkins type 1) (Jasqui-Remba and Rodriguez-Corlay, 2016; Urrutia et al., 1999).
There is a risk of misdiagnosis in these cases since the astragulus fracture might not show up in an X-ray, as in the case presented. A CT scan can detect the fracture and thus help consolidate the bone correctly. The correct differential diagnosis also reduces the risk of avascular necrosis, which increases due to poor blood supply to the astragalus.
Abstract The fields of emergency medicine and resuscitation are indebted to the Baron Dominique-Jean Larrey (1766–1842) for significant advances in patient care. Larrey was a great surgeon who served ...in the French army during Napoleon's rule. He developed one of the first ambulance services, utilized positive pressure ventilation, and introduced hypothermia as a form of therapy. He dedicated his professional life to improving the care of wounded soldiers on the battlefield. Larrey coined the term “Triage” to allocate resources to those most in need of emergent care. Today, many of his techniques still prevail in modern medicine.
In this case report, we present an acute rupture in the muscular tendinous junction of a posterior tibialis muscle in a bimalleolar closed ankle fracture after a high-energy trauma in a 30-year-old ...patient with no significant medical history. Fracture was confirmed by simple X-rays, and was treated with an open reduction in which both of the fractures were treated with osteosynthesis material and reparation of the syndesmosis. If left untreated, this uncommon finding can result in a bad postsurgical outcome; we believe this injury is more common but under-reported in the literature. The surgeon should be aware and look specifically for this type of lesion during the procedure. Finding and treating this injury requires special postoperative care, non-weight-bearing instructions and balanced physiotherapy.
•Catastrophic wear is a rare outcome following Total Hip Arthroplasty.•The main cause of catastrophic wear was secondary to regular usage.•Sudden pain in patients with prosthesis, should lead to an ...immediate image study.•Patients with catastrophic wear usually have good long-term outcome after a revision THA.
Catastrophic wear is a rare outcome following Total Hip Arthroplasty (THA), documented to happen in less than 0.5% of THA. We present 5 cases of revision THA performed successfully on 5 patients presenting Catastrophic wear, following Total Hip Arthroplasty (THA). Specifically, Catastrophic wear cases were selected, emphasizing differential diagnosis, and a revision THA was performed in all of them and resulted in a good long-term outcome.
The purpose of this case series is to contribute to the literature in evaluating both the causes of implant failure as well as the outcomes after their revisions.
We evaluated 5 patients that presented Catastrophic rupture of acetabular implants in a 3-week period in our prosthesis center.
The 5 patients were females, the mean age was 56 years (44–65), the mean post-surgery time was 20 years (17–23), 4/5 of the coupling wear was ceramic–polyethylene and only one case was metal–polyethylene; 4/5 had bilateral total hip replacement. In the 5 cases a revision THA was performed, all with a successful outcome.
Catastrophic failure is an unusual entity; however, when a patient with a prosthesis presents with sudden pain, an immediate image study is indicated, with careful attention to the differential diagnosis, so as to accurately advice receiving a revision THA. The main causes of implant failure are implant duration, volumetric wear and subsequent rupture. Patients with Catastrophic wear and implant rupture, treated with a revision THA, usually have a good long-term outcome.
