Motion of the metatarsophalangeal joints is essential for the normal gait. Therefore it is important to recover the motion of normal joint in the treatment of stiffness of the metatarsophalangeal joints. However, there have been no report about the treatment of stiffness of the four lateral lesser metatarsophalangeal joints yet. We report an experience that good clinical and radiographic results were obtained after resection arthroplasty for the post-traumatic stiffness of the four lateral lesser metatarsophalangeal joints.

A case of hair strangulation on right toe of two months old female patient is reported together with a brief review of references in this paper. This hair strangulation was on the proximal interphanlangeal joint of the right third toe. The distal portion of the hair strangulation was discolored as black, swollon, cold and no evidence of circulation. Amputationon the metatarsophalangeal joint was done.

Dislocations of the toes are comparatively rare. The majority of the these injuries occur in the great toe at the metatarsophalangeal joint. Dislocations of the interphalangeal joint of the great toes are extremely unusual, especially interphalangeal dislocation of the grcat toe with interposition of a sesamoid bone is extremely rare. Authors wishes to report two cases of interphalangeal dislocation of the great toe with interposition of the interphalangeal sesamoid.

The Akin osteotomy is a complimentary procedure in hallux valgus surgery. Surgical techniques may vary depending on the operators or fixation devices. Suture fixation, for which a removal procedure is not necessary, can often be recommended. However, there is a risk of failure due to the thin cortex of the phalanx. We describe a new technique using Ethibond suture fixation in Akin osteotomy, which can lower the risk of phalangeal cortical failure and articular cartilage irritation. First, the Akin osteotomy was performed on the proximal phalanx 5 to 6 mm distal to the first metatarsophalangeal joint. Then bone holes were drilled from dorsum to plantar parallel to osteotomy with the Kirschner wire. The final procedure involved passing the Ethibond sutures connected to a straight needle through the holes and tying it. This fixation method offers an effective and easy technique for performance of Akin osteotomy.

Dislocation of the metatarsophalangeal joint is rare due to the stability of the ligaments and soft tissue surrounding the joint. The authors have experienced lateral dislocation of the first metatarsophalangeal joint, which required surgery, accompanied by complete injuries of medial collateral ligament and capsule, contributing to medial stability, differing from posterior dislocation with intersesamoid complex rupture, with a review of the relevant literature and previous reported cases.

Capsuloligamentous injury at the first metatarsophalangeal (MTP) joint is a common traumatic injury during physical activity, particularly on artificial turf. Mechanism of injury include excessive flexion, extension, or valgus stress. We report a non-operatively treated capsuloligamentous injury at the first MTP joint, which did not occur traumatically but developed by a stress-related mechanism in a collegiate rower.

An unstable second metatarsophalangeal joint may produce pain in the forefoot. Plication of stretched lateral ligament and capsule and transfer of the extensor digitorum brevis under the transverse intermetatarsal ligament performed as the primary procedure to stabilize this painful joint. But the pain was not subsided and the proximal phalanx was resubluxated. So, we osteotomized the second metatarsal to restore a normal alignment of the second toe. Then the symptom was subsided. We report a case of painful instability of the metatarsophalangeal joint of the second toe.

The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FMJC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.

Avascular necrosis of the first metatarsal head is uncommon. It is most often seen following a distal metatarsal osteotomy for hallux valgus. Although many cases may be subclinical, it is a powerful cause of failure of bunion surgery. Avascular necrosis of the first metatarsal head results in a series of events that begins with phases of avascularity; revascularization, with or without collapse; and reossification. Collapse may result in degenerative change of the metatarsophalangeal joint. We have recently experienced a case of avascular necrosis of the first metatarsal head.

Synovial chondromatosis is an uncommon non-neoplastic condition of the joints, forming multiple cartilaginous nodules in the synovium. The lesion usually tends to involve large joints, and the occurrence in the small joint of foot is very rare. We would like to report a case of synovial chondromatosis which was confused with Freiberg infarction in the 1st metatarsophalangeal joint of the foot.
