Metopic synostosis is thought to have an incidence of about 1 in 15,000 births. Traditionally, this makes it the third most frequent single-suture craniosynostosis, after scaphocephaly (1 in 4200-8500) and plagiocephaly (1 in 11,000). Our units have, independently from each other, noted a marked increase in the number of metopic synostosis over the recent years. This is a pan-European, retrospective epidemiological study on the number of cases with metopic synostosis born between January 1, 1997, and January 1, 2006. This number was compared to the prevalence of scaphocephaly, the most frequently seen craniosynostosis. In the 7 units, a total of 3240 craniosynostosis were seen from 1997 until 2006. Forty-one percent (n = 1344) of those were sagittal synostosis, and 23% (n = 756) were metopic synostosis. There was a significant increase of the absolute number as well as of the percentage of metopic synostosis over these years (regression analysis, P = 0.017, R2 = 0.578) as opposed to a nonsignificant increase in the percentage of sagittal synostosis (P > 0.05, R2 = 0.368). The most remarkable increase occurred around 2000-2001, with the average of metopics being 20.1% from 1997 to 2000 and 25.5% from 2001 to 2005 (independent t-test, P = 0.002). The sagittal synostosis showed a smaller and nonsignificant increase in the same years: from 39.9% in 1997-2000 leading up to 42.5% in 2001-2005 (independent t-test, P > 0.05). The number of metopic synostosis has significantly increased over the reviewed period in all of our units, both in absolute numbers as in comparison to the total number of craniosynostosis.

Flexor hallucis longus tendon transfer using a single-incision technique results in decreased flexion power at the IP joint as demonstrated by decreased distal phalangeal pulp pressure; however, this appears to be a laboratory finding as patient function remains high.

Critical review of the available evidence indicates that a relationship exists between sufficient vitamin D status and stress fractures, although genetic and environmental factors are involved as well. Patients at high risk for stress fracture should be educated on protective training techniques and the potential benefits of supplementation with combined calcium and vitamin D, particularly if increased exercise is planned during winter or spring months, when vitamin D stores are at their lowest. The amount of vitamin D intake required is highly variable depending on many factors including sun exposure, and therefore many recommendations have been made for daily vitamin D intake requirements. While the Institute of Medicine guidelines suggest that 600 to 800 IU of vitamin D are required for adequate bone health in most adults, we recommend that most patients receive 800 to 1,000 IU and perhaps as high as 2,000 IU of vitamin D3 as outlined by the previously mentioned review article since vitamin D is a safe treatment with a high therapeutic index. Also, at least 1,000 mg of calcium per day is required for optimal bone health and 1,200 mg may be needed in certain populations. Orthopaedists should consider prescribing vitamin D and calcium prophylactically in high-risk patients. In patients in whom deficiency is a concern, serum 25(OH)D level is the appropriate screening test, with therapeutic goals for bone health being at least 50 nmol/L (20 ng/mL) and may be as high as 90 to 100 nmol/L (36 to 40 ng/mL).

Level III, comparative series.

Background Implanon ® insertion appears to be an easy procedure, but in a small minority of cases difficulties have been encountered with removal if the rod is impalpable.Methods Patients were referred to the contraceptive and sexual health service with non-palpable Implanon. Following a clinical assessment and examination of the arm where the implant had been inserted, an ultrasound examination was carried out to identify and locate the implant. These implants were subsequently removed, some under general anaesthesia and others under local anaesthesia.Results Twenty-seven patients were referred to the unit with impalpable Implanon rods. In four cases the rods were palpable and were removed in the clinic setting without the need for further intervention. Positive identification of the implants was achieved in 21 of the remaining 23 cases using ultrasound. No implant was detected in two cases and etonogestrel was not demonstrated serologically in either woman, suggesting non-insertion. All 21 Implanon rods identified by ultrasound were successfully removed. In just over 52% of women a previous attempt at removal had been undertaken prior to referral. Conclusions It is possible to identify and locate impalpableImplanon rods with the aid of ultrasound, facilitating their subsequent safe removal. Although previous reports have identified the position of 'lost' implants using ultrasound, this is the first case series to discuss measuring the skin/implant depth. This parameter, together with the precise position of the implant (in muscle or fat), aids removal. All health professionals inserting and removing contraceptive implants should have been appropriately trained. Key message pointsG Non-palpable Implanon ® rods are not radio-opaque but can be identified and located by ultrasound scanning carried out by a skilled ultrasonographer.G Ultrasound detection facilitates safe and uneventful removal of the contraceptive implant.G Early referral of women with non-palpable Implanon rods to centres of expertise should be made to avoid unnecessary patient distress. Clinicians should not attempt removal themselves.G Care should be taken at insertion to ensure subdermal placement of the Implanon rod.

This retrospective review identified location in the second webspace as a possible prognostic indicator of poor outcome, but the more important finding may be that outcomes of neuroma excision do not appear to be as successful at long-term followup as previously reported.
