Apatite calcific periarthritis of the radial collateral ligament of the thumb: a case report and review of the literature.

Calcification of the lateral collateral ligament of the metacarpophalangeal thumb is a rare pathology. It's may be due to a deposit of hydroxyapatite crystals. We report the case of a 36-year-old man with chronic pain of MCPP. X-ray and Ultrasound finds a calcium deposit of LCL.

Spontaneous and simultaneous complete bilateral rupture of the quadriceps tendon in a patient receiving hemodialysis: A case report and literature review.

The spontaneous and simultaneous rupture of both quadriceps tendons is uncommon and has rarely been reported in the literature. The current case involves a 43-year-old man with end-stage renal disease requiring hemodialysis for the past 20 years. The patient experienced bilateral knee pain and swelling and was unable to bear weight. Physical examination revealed bilateral quadriceps tendon defect above the patella and loss of active extension. Although plain radiographs of both knees showed no fracture or widening of the joint space, an inferiorly positioned patella was observed. Ultrasonography of the knees revealed a quadriceps tendon defect at the upper edge of each patella, while MR imaging revealed a tear in each quadriceps tendon from the superior poles of the patella. The patient then underwent surgical correction wherein the tendons were repaired using sutures passed through drill holes in the patella. The knees were immobilized with splints for 4 wk before starting physiotherapy. The patient subsequently regained full functional activity within 1 year.

Pseudarthrosis of the Calcaneus: Advantages of Regenerative Medicine in the Management of a Rare Entity, A Case Report and Review of Literature.

BACKGROUND: The follow-up of calcaneal fractures has shown that they are difficult to manage and lead to multiple complications such as malunion and subtalar osteoarthritis. Pseudarthrosis of the calcaneus is an extremely rare complication, which was described in the literature through case reports.In the existing literature, only seven studies, including thirteen patients have reported the nonunion. However, to the best of our knowledge, no study elucidates the role of new techniques of regenerative medicine such as Bone Marrow Concentrates (BMC) or Platelet Rich Plasma (PRP) in the management. METHODS: We report a case of a patient with a pseudarthrosis after a calcaneal fracture treated with BMC injection in the non-union site, without the need for surgical approach. RESULTS: Four months after treatment, the patient was ambulant without support and was completely pain-free. Moreover, after one year the radiological follow up by CT scan showed a satisfactory filling of the non union. CONCLUSION: In one case, we try to highlight the advantage of our therapeutic alternatives, which are having a good union while avoiding the complications of surgical approaches and without sacrificing the subtalar joint when it is possible.

Scurvy: When it is a Forgotten Illness the Surgery Makes the Diagnosis.

BACKGROUND: Unlike most of animal species, human beings lack the enzymatic process for the conversion of glucose to ascorbic acid (vitaminC), and therefore getting the vitamin from food sources is essential. The association of the various signs caused by a deficiency of vitamin C is called scurvy or Barlow's disease, an easily treatable disease but can be fatal. It is rare in the developed countries and even economically underdeveloped societies in which the basic diet is already rich in ascorbate. METHODS: We describe here the case of a 4-year-old girl with cerebral palsy, in whom diagnosis concerns were oriented for osteomyelitis, based upon clinical presentation, ultrasonic and magnetic resonance imaging, led to a surgery revealing subperiosteal hematomas that argues in favor of scurvy. RESULTS: After vitamin C therapy, the symptoms are gone and the general condition of the patient improved despite persistent radiological signs. CONCLUSION: Recent studies of sporadic cases report a high incidence of scurvy in children with autism or psychomotor retardation and the fact that musculoskeletal manifestations are more common. The mosaics of the symptoms of scurvy are varied and include dermatological, dental, bone and systemic manifestations, making it a forgotten and misdiagnosed illness. A heightened awareness is needed to avoid an unnecessary surgery, unnecessary tests and procedures and to be able to start treatment for a potentially fatal but easily curable disease.
