Rupture of the plantaris muscle may occur at the myotendinous junction with or without an associated hematoma or partial tear of the medial head of the gastrocnemius muscle. A strain of the more proximal plantaris muscle may also occur as an isolated injury or in conjunction with injury to the ACL.

Magnetic resonance imaging (MRI) was performed on the wrists of 103 asymptomatic volunteers. The images were evaluated independently by two musculoskeletal radiologists and one orthopaedic surgeon. Wrist ganglia were identified in 53 out of the 103 wrists. The average long and short axes measurements were 8 mm (range 3-22) and 3 mm (range 2-10), respectively. Seventy per cent of the ganglia originated from the palmar capsule in the region of the interval between the radioscaphocapitate ligament and the long radiolunate ligament. Fourteen per cent of the ganglia were dorsal and originated from the dorsal, distal fibres of the scapholunate ligament. Two ganglia had surrounding soft tissue oedema and one had an associated intraosseous component. Unlike previous surgical and pathological series, our study showed that palmar wrist ganglia are more common than dorsal wrist ganglia. The vast majority of these asymptomatic ganglia occur without associated ligamentous disruption, soft tissue oedema or intraosseous communication.

Impingement of the rotator cuff on the posterior superior glenoid labrum is a cause of posterior shoulder pain in athletes who throw. MR arthrography may allow detection of abnormalities associated with this clinical entity.

Uterine arteriovenous malformations (AVM) are rare and can be classified as either congenital or acquired. Acquired AVMs may result from trauma, uterine instrumentation, infection or gestational trophoblastic disease. The majority of acquired AVMs are encountered in women of reproductive age with a history of at least one pregnancy. Traditional therapies of AVMs include medical management of symptomatic bleeding, blood transfusions, uterine artery embolization (UAE) or hysterectomy. In this retrospective case series, we report our experience with AVM and UAE in five symptomatic women of reproductive age who wished to preserve fertility. Patients were 18-32 years old, and had 1-3 previous pregnancies prior to initial presentation. All patients were followed until their deliveries. All five patients delivered live births. Three of the five patients required two embolization procedures and one of these women required a subsequent hysterectomy. Two deliveries were at term and had normal weight babies and normal placenta. One woman had cerclage placed and developed chorioamnionitis at 34 weeks but had a normal placenta. Two pregnancies were induced <37 weeks for pre-eclampsia/b intrauterine growth restriction ± abnormal umbilical artery dopplers. The low birthweight were both <2000 g. Both placentas showed accelerated maturity and infarcts. All estimated blood losses were recorded as <500 cc. In conclusion, UAE may not be as effective at managing AVM as previously thought and should be questioned as an initial therapy in symptomatic women of reproductive age desiring fertility preservation.

This preliminary study examines correlations between age-at-death and changes in the trabecular architecture of the human os pubis, utilizing continuous, quantitative data from plain film radiography, computed tomography (CT), and micro-CT scans of 65 male innominates. Radiography provides nondestructive options for assessment, digital preservation, and presentation of human skeletal remains; important for forensic and culturally sensitive archaeological materials, which must remain unmodified for opposing experts, future researchers, or repatriation and reburial. Radiographic techniques permit analysis of remains that cannot be disarticulated (e.g., religious proscription, mummies), and trabecular measures provide data where traditional surface indicators are obscured or damaged. Potentially, robust predictive models derived herein achieve R-values of 0.522, 0.447, and 0.731, respectively. Further testing of these methods may validate these techniques as further lines of evidence in age estimation, with the potential to improve on the accuracy of traditional qualitative techniques by providing quantitative, continuous variables in predicting skeletal age-at-death.
