Foot shape and radiographs of free-ranging Nubian giraffe in Uganda

Foot health in zoo giraffe has been a topic of recent research, although little is known about the foot health of free-ranging giraffe. This study describes the foot shape and radiographic pathological changes in 27 young adult Nubian giraffe (Giraffa camelopardalis camelopardalis) from a translocation in Uganda (August 2017). Giraffe feet were observed to have a concave sole, the hoof wall was longest by the toe tip, and the weight-bearing surface of the foot was primarily along the periphery of the foot including hoof wall, parts of the heel, and the edge of the sole. Radiographs showed that pedal osteitis and sesamoid bone cysts were relatively uncommon (3/24 giraffe with osteitis, 1/24 giraffe with sesamoid cysts), and that no giraffe in the study had P3 joint osteoarthritis, P3 rotation, or P3 fractures. Radiographs consistently demonstrated a positive palmar/plantar angle with the sole of the hoof thicker at the heel than by the toe tip, with the non weight-bearing palmar/plantar angle measuring 1.6°- 4.3°. This is the first systematic review of foot shape and radiographs in free-ranging giraffe and demonstrates a low prevalence of foot pathologies. This study suggests qualitative differences in foot shape, foot health, radiographic anatomy, and foot pathologies when comparing free-ranging and zoo giraffe. Further research is needed to identify why these differences occur and whether husbandry modifications could help improve zoo giraffe foot health and prevent associated lameness.

Two rare cases of cystic angiomatosis and a literature review

Cystic angiomatosis is a rare disease characterized by disseminated multifocal hemangiomatous and/or lymphangiomatous cystic lesions of the skeleton with possible visceral organ involvement. Only a few dozens of such patients worldwide have been described in the literature. This article presents two case reports of the patients admitted to the D. Rogachev NRMCPHOI with suspected Langerhans cell histiocytosis. The patient’s parents gave their consent to the use of their child’s data, including photographs, for research purposes and in publications. During the investigation, multiple cysts of the skull bones, spine, pelvic bones and limbs, as well as of the spleen were found in both patients. A biopsy of the bone cysts of the skull revealed no data in favor of histiocytosis or other neoplasms. Cystic angiomatosis was diagnosed in both cases. This is a rare disease that should be kept in mind in the differential diagnosis in patients with cystic lesions of the bones and visceral organs.

Rare right acetabulum aneurysmal bone cyst treated with curettage and local adjuvants in a 4-year-old girl

Aneurysmal bone cysts are locally aggressive benign bone tumours with a high risk of recurrence. We describe a case in a 4-year-old girl, involving the right acetabulum. A direct posterior approach was used and the lesion ablated with curettage and local adjuvants with bone grafting. The cyst resolved swiftly with an uncomplicated recovery.

Greater wing of sphenoid, the home for aneurysmal bone cysts: a case report

Background Finding an aneurysmal bone cyst in the skull is rare and for a neurosurgeon to come across such lesions in the sphenoid bone with orbital extension is even rarer. Case presentation We report a case of a 16-year female who presented with a three-month history of headache, proptosis, and deterioration of vision. Pre-operative imaging studies which included NCCT head and MRI brain, suggested the lesion to be an aneurysmal bone cyst of the greater wing of the sphenoid, with extension into the orbit. Intraoperative findings did corroborate with the preoperative imaging findings and were again confirmed later from the histopathology report. Conclusion Aneurysmal bone cysts of sphenoid bone with orbital extension, though rare, can be excised completely, without hampering the cosmesis. Being benign, patients can have a prolonged recurrence-free period if the lesion is completely excised.

Successful treatment of a symptomatic unicameral calcaneus bone cyst by cement injection using a double needle technique under CT guidance: a case report

Simple bone cysts (SBCs) are benign cavitary lesions which most commonly affect adolescent males in the first two decades of life. They are mainly asymptomatic, but can manifest with pain or pathological fractures. A 16-year old girl presented with an 8-day history of pain and swelling over the right calcaneal region. On local examination, tenderness was the only noteworthy sign and all routine laboratory tests conducted revealed normal results. Despite numerous proposed methods for the management of calcaneus SBCs, the optimal approach towards these lesions remains controversial. Here, a novel method utilizing a minimally invasive technique is proposed to successfully manage these lesions. In an outpatient setting, under conscious sedation, two interosseous needles were simultaneously inserted into the cyst under the guidance of CT fluoroscopy. Without aspiration, a radiopaque bone cement mixture was injected into the cyst from one needle until the cessation of serosanguineous fluid efflux from the second needle. Over a one-year follow-up period, the patient recovered without any complications. Bone cement injection using a double needle technique under CT fluoroscopy guidance is a feasible and safe method to treat symptomatic unicameral calcaneal bone cysts.

Recent Trends in the Management of Aneurysmal Bone Cyst

Background Aneurysmal bone cysts (ABCs), were first described by Drs. Jaffe and Lichenstein in 1942 when they described pelvic and spine lesions that when exposing the lesion and opening in to its thin wall, the surgeon was immediately confronted by a large hole containing much fluid blood. Aim of the Work To describe the efficacy of new line treatment modalities of (Aneurysmal Bone Cysts) compared to conventional lines of management regarding the: • Long term outcomes and healing rate. • Recurrence rates. • Complications after therapy. Patients and Methods Criteria for considering studies for this review: • Types of the studies: published observational analytical studies (case-control_ case-series _ RCT or cohort studies) which studied the efficiency of new lines in the management of aneurysmal bone cyst. • Types of participants: participants were children and young age (below the age of 50 yrs) with a diagnosis of aneurysmal bone cyst. • Types of interventions: drugs like (Bisphosphonate or denosumab) were administered for a time determined by the case improvement, or minimally invasive techniques like (cryosurgery or curopsy) was done. Results Through the results of our study that compared between these recent modalities according to healing, recurrence, and complications rate; we are able to say that recent strategies have a high rate of healing ranges from 78.57% with bisphosphonate to 100% with doxycycline and cryotherapy. Conclusion There are recent evolving trends in the management of ABC other than the classic ways of management, they are less invasive, have less recurrence rate reaches to 0 % like with bisphosphonate, less complications rate as well reaches to 0 % like with doxycycline and bisphosphonate, high healing rate reaches to 100 % like with doxycycline and taking in consideration how to handle cases of ABC that classic way of management can’t handle like spinal ABC.
