The osteochondroma is a common benign bone tumor, which is only rarely observed in a subungal location, especially in the fingers. We present a case of multiple subungal osteochondromas, which occurred in the distal phalanges causing nail deformities and pain.

Congenital onychodysplasia of the index fingers (COIF, Iso and Kikuchi syndrome) is a congenital disorder characterized by various forms of nail dysplasias mainly-involving the index fingers. Its etiopathogenesis is still unknown, but ischemia of the palmar digital arteries has been suggested to play a role in this disorder. Although not specific to it, a Y-shaped bifurcation of the distal affected phalanx is a characteristic finding of this syndrome. In this review, we report a case of COIF who presented with bilateral micronychia with a Y-shaped bifurcation of the distal phalanx.

PURPOSE: A lot of surgical techniques were tried to correct extension lag of distal interphalangeal joint. Spiral oblique retinacular ligament reconstruction is the one of correction techniques. METHODS: From January 2004 to January 2005, a total of 13 extension lag of distal interphalangeal joint corrections were performed using spiral oblique retinacular ligament reconstruction for 11 patients. After dorsal incision exposing from base of distal phalanx to proximal phalanx, the new ligament(half of lateral band or graft tendon) lies distally at the dorsum of the distal phalanx and passes volarly and proximally along the side of the middle phalanx and anterior and obliquely across the front of the proximal interphalangeal joint to the opposite side of the digit at the proximal phalanx. RESULTS: 5 of 6 mallet finger deformities and 7 swan neck deformities were corrected, which were both extension lag of distal interphalangeal joint and hyperextension of proximal interphalangeal joint. CONCLUSION: As a result, spiral oblique retinacular ligament reconstruction is an effective and recommendable method for correction of mallet finger deformity and swan neck deformity.

Extraskeletal chondromas are benign soft tissue tumor of hyaline cartilage. These tumors are rare and the pathogenesis is unclear. They are usually involves the hand or feet. We report the case of extraskeletal chondroma arising from subungual region of the finger with nail deformity and review of the literature.

Infantile digital fibromatosis(IDF) is a rare, benign fibrous tumor, first described in 1965 by Reye. IDF may occur single or multiple lesions exclusively on the fingers or toes, rare occurrence outside the digit have been reported. This tumor grow slowly and may adhere to the deeper tissue, and may lead to deformity of the digit, but do not distant metastasis or dissemination. There is a marked tendency for recurrence after surgical excision. Up to now, only 6 cases have been reported in the literature showing spontaneous regression. We experienced a case of infantile digital fibromatosis located on hypothenar area at birth. Also that spontaneous regressed at 13 months of age. We reported a case of IDF showing spontaneous regression with brief review of related literature.

After operation for fracture in the phalangeal bones, rehabilitation is initiated in order to minimize joint stiffness if in the case, complete bony union is confirmed by hand surgeons. The described case demonstrates that bony mallet deformity can occur during physical therapy following by surgical pinning of a proximal phalangeal fracture. This mallet finger deformity occurred due to vigorous rehabilitation for correction of postoperative joint stiffness. So, when hand surgeons treat patients with proximal phalangeal fracture, it is important to minimize joint space involvement and close follow-ups accompanying imaging studies during rehabilitation period.

Six thumb reconstructions and one index reconstruction were performed by use of the wrap-around technique. All successful digital reconstructions were reviewed at an average of 37 months after surgery. There were complications related to the digits in three patients ; these included pin site infection (1), malrotation (1), and nail deformity (1). But we considered that function and cosmesis were excellent with a 100% viability rate. All patients regained protective sensation and sttained two-point discrimination (average 10mm). The wrap-around technique represents an esthetically and functionally excellent procedure of digit reconstruction for amputation at the level of metacarpo-phalangeal joint or distal to it.

The hook-nail deformity after finger tip amputation is very common problem. This usually occurs after loss of part of the distal pulp, phalanx, and nail bed. This deformity for some patients is a trivial lesion and may be ignored, but it may be of great cosmetic significance or disabling with regard to certain occupations to the others. To correct the deformity, it is necessary to release volarly displaced nailbed, return it to its normal position, and provide adequate support to maintain correction by a carefully planned "antenna" procedure. Deformed nail is removed, tethered pulp is freed from distal phalanx, and then full thickness of the nail bed is elevated and splinted with multiple small Kirschner wires in a straight position like antennae. The coverage of defect created is done by cross finger flap. The knowledge of anatomy and physiology of nail and sorrunding structures is important to obtain good results and reduce secondary deformities. Two cases of antenna procedures for the hook nail deformily is reported with good results.
