Lipoma Arborescens in a 16-year old male: A case report

Lipoma arborescens is a benign intra-articular tumor characterized by joint effusions, pain and reduced range of motion. It is rare in adults and children. We present a case of Lipoma arborescens in a 16 year old male. The work up involved plain radiographs, MRI, incisional biopsy and laboratory analysis.

Plantar forefoot pain: ultrasound findings before and after treatment with custom-made foot orthoses

Purpose No prior studies investigated the role of ultrasound in the assessment of response of patients undergoing treatment of metatarsalgia with custom-made orthoses. Our aim was to describe ultrasound findings of patients with plantar forefoot pain treated with custom-made foot orthoses. Methods Twenty patients (15 females; mean age: 62.6 ± 11 years) affected by metatarsalgia in 27/40 feet underwent clinical evaluation before, three months and six months after treatment with custom-made full foot insole with a support proximal and an excavation below the painful metatarsals. Ultrasound was performed before and three months after the use of orthoses to examine the presence of intermetatarsal/submetatarsal bursitis, metatarsophalangeal joints effusion, anterior plantar fat pad oedema, flexor tendinitis/tenosynovitis, and Morton’s neuroma. Outcome measures were clinical response with Foot Function Index (FFI)/Visual Analogue Scale (VAS) and ultrasound features changes. Results Median VAS and FFI before treatment were 8[5–8.5] and 45.85[32.4–59.4], respectively. After 3 and 6 months of insoles use, both median VAS (2.5 [0–5] and 0 [0–2.75], respectively) and median FFI (7.9 [3.95–20] and 0 [0–3.95], respectively) showed a significant reduction in pain and disability (p < .001). Before treatment, ultrasound revealed 22 intermetatarsal bursitis, 16 submetatarsal bursitis, 10 joint effusions, 20 fat pad oedema, 3 flexor tendinitis/tenosynovitis and 3 Morton’s neuromas. After 3 months of treatment, a significant decrease of intermetatarsal bursitis (7, p < .001) was observed. No significant changes were observed in any other ultrasound parameters. Conclusion Ultrasound might be able to detect some imaging features associated with the response of forefoot pain to custom-made foot orthoses, especially intermetatarsal bursitis.

Influence of outpatient total knee arthroplasty compared to inpatient surgery on medical and economic outcomes

Firstly, this study compared the rate of readmission after a total knee arthroplasty between selected out- patients (no hospitalization, directly sent home after surgery) and inpatients (3 days hospitalization) at 6 weeks. Secondly, it examined the mobility and the complications in the two groups after the same period of time. The rate of readmission, complications and knee mobility of 32 outpatients (M-age : 61 years ± 10 ; 10 females), were compared against those of 32 birth- matched inpatients (M-age : 64 years ± 8.6 ; 10 females). No patient was re-admitted in either group. Post- surgical complications included one hematoma resorbed at 6 weeks in the outpatient group and three joint effusions in the inpatient group. There were no instances of deep venous thrombosis, failure of primary fixation, infection, or wound dehiscence. Knee mobility was identical between the two groups. This is the first study to compare inpatient and outpatient total knee arthroplasty in a Belgian setting. Our study suggests that day-care total knee arthroplasty in selected patients is possible without increasing the rate of re-admission and complications, and without affecting the mobility at 6 weeks. However, the Belgian financial incentives do not seem to currently promote this surgical approach. These results should be confirmed with a larger sample to define the adequate length of stay after a total knee arthroplasty.

Case Report of Osteopoikilosis: Sparse Cause of Bone Pain and Mimicker of Metastasis on Radiographs

Introduction: Osteopoikilosis (OPK) is an extremely rare benign condition with autosomal dominant inheritance characterized by sclerosing bony dysplasia with multiple benign enostoses. It is characterized by symmetrically distributed numerous, small, well-defined, homogenous circular or ovoid radiodensities clustered in epiphysis and metaphysis of long bones in periarticular region, and in some cases diffusely present throughout axial and appendicular skeleton. There is no age and sex predilection; age at the time of diagnosis ranges from 15 to 60 years. It is usually asymptomatic but rarely in 15–20% patients slight juxta-articular pain and joint effusions can be seen. These are incidental radiological findings in most of the cases, also sometimes confused as bony metastasis. There are no specific clinical features; histological features are similar to bony island and it may be associated with connective tissue disorders, synovial osteochondromatosis, and a rare bone condition melorheostosis. Case Report: We present a case of OPK in a 32-year-old male with bilateral hip and shoulder pain, based on the available literature and focus on clinical significance, due to its mimicking capability of other more severe conditions such as bone metastases and an extremely uncommon cause of bone pain. Conclusion: OPK is an uncommon hereditary condition involving juxta-articular region of long bones with intricate etiopathogenesis, often discovered incidentally on radiographs. It is characterized by multiple, symmetrical ovoid radiodensities, and in most instances confused with osteoblastic metastasis. This concludes that OPK is a condition that should be kept in mind to avoid misdiagnosis, in particular osteoblastic metastasis and undue distress to both the patients and doctors.
