Complications of Nail Surgery: A Review of the Literature

DERMATOLOGIC SURGERY, Issue 3 2001
Meena Moossavi MD
Background. The realm of nail unit surgery encompasses the dermatologist as well as the hand surgeon. Nail surgery complications may include allergy to anesthetic, infection, hematoma, nail deformity, and persistent pain and swelling. Objective. To review the pertinent literature regarding nail unit surgery complications. Methods. A Medline literature search was performed for relevant publications. Results. Nail unit surgery complications appear to be relatively infrequent. The majority of postoperative nail deformity complications result from nail matrix damage. Conclusion. Complications may be reduced to a minimum by preventive measures, such as careful patient selection, sterile technique, and gentle treatment of the nail matrix. [source]

Risks of allogeneic hand transplantation

MICROSURGERY, Issue 2 2004
Steffen Baumeister M.D.
A patient undergoing allogeneic hand transplantation needs lifelong immunosuppression with the risk of serious side effects, including life-threatening disease. The question remains: does the eventual improvement in function justify the risk? To answer this question, we try to assess the risks based on a large body of cumulative data derived from more 200,000 kidney transplants using the Collaborative Transplantation Study (CTS). Only selective data which apply to a patient population aged between 15,40 years were used (n = 58,310). Data are compared to the literature references and show superiority with respect to patient numbers, statistics, actuality, and methodology. The CTS data show that the incidence of de novo malignancies is lower than previously reported. The risk of developing any form of cancer is approximately 3%, of developing a skin cancer 1.1%, and of developing a lymphoma 0.58% within 5 years after transplantation. The risk of suffering from a cataract is 11% after 5 years, which is also lower than previously reported. Although the incidence of side effects (particularly malignant disease) is likely to be lower than previously thought, the risk-benefit question must be answered by each hand surgeon for each individual patient. © 2004 Wiley-Liss, Inc.

The contribution of the palmaris longus muscle to the strength of thumb abduction

CLINICAL ANATOMY, Issue 4 2010
Hope Gangata
Abstract The palmaris longus muscle (PLM) is described as a weak flexor of the wrist and a tensor of the palmar aponeurosis, but not a thumb abductor. The PLM is believed to aid thumb abduction through its insertion onto the thenar eminence. Two groups, both right hand dominant, were selected from 1,200 sampled participants. The first group comprised of 38 subjects with unilateral presence of the PLM and was used to determine the strength of thumb abduction. The second group comprised of 30 subjects, with bilateral presence of the PLM, and it was used to calculate the effects of hand dominance. A significant number of subjects with bilateral absence of the PLM were observed and undocumented. Using a dynamometer in subjects with unilateral presence of the PLM, the force of thumb abduction was significantly greater on the hand with a PLM than the one without it (P = 0.014), irrespective of hand dominance. In the second sample with bilateral PLM, thumb abduction on the dominant hand was 10% stronger than on the nondominant hand and was similar to the universally accepted average of 10% increase in grip strength of the dominant hand. Thus, 10% was deducted from all the dominant hands, and the force of thumb abduction remained greater on the hand with PLM than the hand without it (P = 0.049). The results of this study demonstrated the PLM to be involved in thumb abduction, and the authors therefore recommend that this action of the muscle be universally accepted by anatomists and hand surgeons.

Communications between the palmar digital branches of the median and ulnar nerves: A study in human fetuses and a review of the literature,

CLINICAL ANATOMY, Issue 2 2010
Nadire Unver Dogan
Abstract In this study, median nerves (MNs) and ulnar nerves (UNs) were dissected in 200 palmar sides of hands (left and right) of 100 (50 male, 50 female) spontaneously aborted fetuses with no detectable malformations. The fetuses, whose gestational ages ranged from 13 to 40 weeks, were dissected under an operating microscope. The MN divided first into a lateral ramus and a medial ramus and then formed a common digital nerve. The first common digital nerve trifurcated in all of the studied cases. The branching patterns were classified into two types (Type 1 and Type 2) based on the relationship with the flexor retinaculum (behind/distal of it). A communication branch between the UNs and MNs in the palmar surface of the hand was found in 59 hands (29.5%). The proper palmar digital nerves were numbered from p1 to p10, starting from the radial half of the thumb to the ulnar half of the little finger, and these nerves exhibited six types of variations. The present data obtained from human fetuses will aid in elucidating the developmental anatomy of the nervous system and provide hand surgeons with a more complete anatomical picture to help them to avoid iatrogenic injuries.
