Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

PURPOSE: To evaluate the effect of shortening scarf osteotomy on pain relief and range of motion (ROM) of the first metatarsophalangeal joint in hallux rigidus patients. MATERIALS AND METHODS: Twenty-three cases of 19 patients who had been treated with shortening scarf osteotomy for the hallux rigidus between January 2007 and December 2013 were reviewed. The mean follow-up period was 21.4 months, and the mean age was 59.2 years. The first metatarsal bone was shortened until the ROM of the first metatarsophalangeal joint was greater than 80° or 40° of dorsiflexion. The length shortened by scarf osteotomy was measured. The authors also measured and compared the joint interval difference of the standing foot using an anteroposterior radiography. Moreover, the difference of ROM of the first metatarsophalangeal joint between the preoperative and final follow-up periods was also compared. The clinical results were evaluated and compared using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and visual analogue scale (VAS) score. RESULTS: The mean shortening length was about 6.5 mm (range, 4∼9 mm). The joint space has been increased to 1.8 mm, and the ROM of the first metatarsophalangeal joint has also been increased to 18.4° after the operation. In three cases, the postoperative ROM has been decreased to less 10°. The AOFAS score has been improved from 41.7 (range, 32∼55) to 86.2 (range, 65∼95), and the VAS score was also decreased from 3.7 (range, 3∼5) to 1.3 (range, 0∼3). Two cases have shown no decrease in pain even after the operation. CONCLUSION: Shortening scarf osteotomy was found to decrease joint pain by decompressing the pressure of the first metatarsophalangeal joint. This osteotomy also helped improve the ROM of the first metatarsophalangeal joint. Shortening scarf osteotomy can be considered one of the effective methods for joint preservation.

PURPOSE: This study was performed retrospectively to evaluate clinical outcomes of distal metatarsal osteotomy using bio-compression screw as the joint preservation method for advanced hallux rigidus. MATERIALS AND METHODS: Eleven cases were followed up for more than 1 year after distal metatarsal dorsal wedge osteotomy for advanced hallux rigidus. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and patient's satisfaction score. The range of motion, and the period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were evaluated. As the radiographic evaluation, the interval of 1st MTP (metatarsophalangeal) joint space and the period to union were measured. RESULTS: The AOFAS hallux score had improved significantly from preoperative average 50.7 points to 87.6 points at the last follow-up (p=0.005). The subjective satisfaction score was average 90.6 points. There were no case of subsequent fusion or additional operation, and no complication associated with bio-compression screw. The period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were average of 24.8 weeks, 20.4 weeks, 16.8 weeks, 18.5 weeks respectively. Dorsiflexion of 1st MTP joint had improved significantly from preoperative average 17.5degrees to 44degrees (p<0.001). All cases achieved union of osteotomy site, and the period to union was average 10.4 weeks. The interval of 1st MTP joint space had improved significantly from preoperative average 1.2 mm to 3.5 mm (p=0.014). CONCLUSION: Distal metatarsal osteotomy using bio-compression screw seems to be one of effective treatment methods for advanced hallux rigidus, because of restoration of the first MTP joint motion, and reliable pain relief, and needlessness of hardware removal.

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

As the aging of the foot progresses, the stiffness of the soft tissues, the reduction of the range of motion, the decrease of the muscle strength, and the flattening of foot are manifested. These changes increase the risk of foot pain, the problem of weight distribution and transmission, and the risk of falls, resulting in secondary complications and lowering quality of life. The most common deformities and diseases of the elderly foot are hallux valgus, hammertoes, hallux rigidus, Achilles tendinitis, plantar fasciitis, metatarsalgia, hyperkeratosis, and other deformities of the feet caused by chronic conditions. Systemic diseases that promote these foot problems include diabetes, peripheral nerve damage, repetitive ankle ligament injuries, deformities due to fractures, and obesity. Understanding the mechanisms of aging and the processing of biomechanics in the elderly will enable them to reach a healthy life through appropriate rehabilitation, exercise and educations during aging. In addition, it is necessary to promote the healthy life in elderly by customized exercise, training, and shoes.
