Carpal Collapse After Scaphoid Nonunion: A Novel Combined Approach to the 1,2 Intercompartmental Supraretinacular Artery Radial Flap.

Purpose: Scaphoid nonunion remains a major problem in hand surgery. The 1,2 intercompartmental supraretinacular artery flap (1,2 ICSRA), as first described by Zaidemberg et al, is widely used with reported union rates of approximately 80%. However, its use is limited in the case of associated carpal collapse as in dorsal intercalated segmental instability (DISI) and humpback deformity. In this study, we present a novel approach to this flap enabling the correction of associated carpal collapse. Methods: Between 2006 and 2015, 9 patients with scaphoid nonunion or delayed union with carpal collapse were treated with a vascularized bone flap based on the 1,2 ICSRA using a combined volar and dorsal approach. Immobilization in a short-arm cast was applied for 8 weeks. Union rates, correction of DISI and humpback deformity, as well as clinical end points were noted. In addition, scapholunate (SL) angles were measured using 2 accepted radiological techniques, employing either the scaphoid midline axis or its proximal radiological landmarks as a reference. Results: All cases united and a median time to bone consolidation of 4 months (range, 2-5 months) was observed. Preoperative DISI deformities (n = 4) were corrected in all patients. Humpback deformities (n = 5) were also corrected. Two patients had repeat surgery: one for K-wire removal after bony consolidation and the other for neuropathic pain. Conclusions: The 1,2 ICSRA bone flap is a reliable treatment for scaphoid nonunion associated with carpal collapse. This combined volar and dorsal approach permits the correction of DISI and humpback deformity without compromising the scaphoid vascular supply, which eliminates the need to use free bone flaps from other sites. In this series, we observed a 100% union rate. Two patients required reoperation for symptomatic hardware and dorsal wrist pain linked to superficial neuritis. Type of study/level of evidence: Therapeutic IV.

Third degree formic acid chemical burn in the treatment of a hand wart: a case report and review of the literature.

OBJECTIVE: Cutaneous warts are very common and a large variety of topical treatments and drugs can be employed to cure these skin injuries that can arise on any part of the body. But are these products really safe? METHOD: We performed a case description and PubMed literature review using key words "wart," "chemical burn," and "formic acid." All articles in English and French were selected. RESULTS: This is the first report of a chemical burn by formic acid in the treatment of warts. Numerous topical treatments for cutaneous warts are available with many new drugs appearing every year. However, only a few treatments have proven their effectiveness, such as salicylic acid or cryotherapy with liquid nitrogen that are commonly used. Moreover, most cutaneous warts will resolve spontaneously without any treatment and several products, including topical acids and cryotherapy devices, presented adverse effects such as chemical burns or frostbites so demonstrating that even frequently used treatments can be harmful. CONCLUSION: Topical treatments used for wart removal are not without risk even if some products are sold without prescription. For self-treatment products, we recommend enhanced warning by the pharmacist about the risks involved.

[Septic arthritis (non gonococcal) of the adult: practical aspects]. / Les arthrites septiques non gonococciques de l'adulte: aspects pratiques.

Septic arthritis is potentially a life-threatening disease and frequently afflicts the most fragile patients. It is crucial to rule-out this diagnosis in a patient presenting with monoarticular arthritis, and the gold-standard is aspiration of the joint. A primary site of infection such as endocarditis or spondylodiscitis must be excluded by appropriate examination and investigative studies. The usual infecting organisms causing septic arthritis are Staphylococcus and Streptococcus species, and in young adults Gonococcus must be considered. Antibiotics should be started promptly after obtaining joint fluid for bacteriologic studies. Efficient drainage and lavage of the joint should be performed without delay because articular cartilage can be damaged quickly. Arthroscopy is a well-accepted technique in treating septic arthritis, particularly when the knee is involved.
