Incomplete development of the nail of the hallux in the newborn
Dermatology Online Journal

Original article:Between March and October 2008, the nails of 541 (252 females, 289 males) consecutively born neonates with an average age of 3.2 days were examined in the Neonatology Unit. Of these newborns with nail disorders, 36 were re-examined after a period that ranged from seven days to six months. The most frequent nail alteration was the incomplete development of the hallux nail, which was triangular – sometimes trapezoidal – shaped. This alteration, which had been previously reported in the literature as congenital hypertrophy of the lateral folds of the hallux, spontaneously regressed within one to three months in the infants re-examined. There was no associated inflammation or onychocryptosis at any time. The apparent hypertrophy of the nail folds seemed to be secondary to the lack of pressure of the nail lamina.
A rare multisystem disorder: Goltz syndrome – Case report and brief overview

Arpita Jain MD, Ram Chander MD, Taru Garg MD, Nikita MD, Gurucharan S Shetty MD
Original article:Focal dermal hypoplasia, also known popularly as Goltz syndrome, is a multisystem disorder characterized by linear or reticulate atrophic macules with fat herniation that is associated with various cutaneous and extracutaneous anomalies. We present a patient with Goltz syndrome who exhibited a classic presentation associated with exophthalmos major and malrotation of the gut. A brief overview of the syndrome is also presented in an attempt to incorporate all associated anomalies reported so far.

Original article:PURPOSE. To investigate anatomic variations of neurovascular structures in the ankle and the safety margin for arthroscopic portals.
METHODS. 11 left and 12 right ankles from 8 female and 15 male fresh cadavers of Chinese ethnicity aged 53 to 88 (mean, 68) years were used. The ankle was standardised in a plantigrade position, zero-degree inversion, and neutral rotation. Four ankle portals, namely anteromedial (AM), anterolateral (AL), posteromedial (PM) and posterolateral (PL), were identified using 23-gauge needles. Skin and subcutaneous fat were dissected from the underlying fascia to visualise neurovascular structures. Distances were measured from: (1) the AM portal to the saphenous vein and nerve and its branches, (2) the AL portal to branches of the superficial peroneal nerves, of which the lateral one was labelled as the intermediate dorsal cutaneous branch and the medial one as the medial dorsal cutaneous branch, (3) the PM portal to the posterior tibial neurovascular bundles, and (4) the PL portal to the sural nerve.
RESULTS. The distances from (1) the AM portal to branches of the great saphenous vein and nerve, and (2) the AL portal to the intermediate dorsal cutaneous branch of the superficial peroneal nerve were short and may be an anatomic hazard. Variations were significant among the cadavers in terms of distances of the portals to the neurovascular structures.
CONCLUSION. In Chinese cadavers, variations of neurovascular structures are significant. Care must be taken to avoid inadvertent injury during ankle arthroscopy.
Use of autologous fibrin sealants to treat ganglion cysts: a report of two cases

Original article:Two patients underwent arthroscopy-guided injections of autologous fibrin sealants to treat ganglion cysts causing suprascapular nerve palsies. After at least 2 years of follow-up, both patients had no suprascapular nerve symptoms and their external rotation strength had returned to normal. Magnetic resonance imaging revealed no evidence of ganglion cyst recurrence.
Noninvasive Quantitative Assessment of Bone Healing After Distraction Osteogenesis
HSS Journal
Oladapo M. Babatunde, Austin T. Fragomen and S. Robert Rozbruch
Original article:One of the greatest challenges of limb lengthening and deformity correction is deciding when the bone has healed enough to remove the external fixator. Standard radiography is the most common imaging method used to assess bone healing after distraction osteogenesis because it is widely available, cheap, and relatively safe. However, other imaging technologies and methods are being investigated that will help quantify bone healing after distraction osteogenesis, providing an objective method for deciding when it is appropriate to remove an external fixator. This review will examine the latest techniques used to assess bone healing after distraction osteogenesis including dual-energy X-ray absorptiometry scans, ultrasound, quantitative computed tomography, and digital radiography (X-ray). Recommendations for clinical practice will be outlined.
