Skin Graft Remains a Clinically Good Treatment Strategy for Chronic Diabetic Wounds of the Foot and Ankle / 대한족부족관절학회지

Purpose@#The purpose of this study was to evaluate the surgical outcome of split-thickness skin graft (STSG) for chronic diabetic wounds of the foot and ankle. @*Materials and Methods@#The medical records of 20 patients who underwent surgery for chronic diabetic wounds of the foot and ankle between October 2013 and May 2018 were reviewed. Surgical management consisted of consecutive debridement, followed by negativepressure wound therapy and STSG. We used an acellular dermal matrix between the wound and the overlying STSG in some patients with wide or uneven wounds. Patient satisfaction, comorbidities, wound size and location, length of hospital stay, wound healing time, and complications were investigated. @*Results@#Of 20 patients, 17 (85.0%) were satisfied with the surgical outcome. Eight patients had diabetic wounds associated with peripheral vascular disease (PVD), 7 patients had diabetic wounds without PVD, and 5 patients had acute infection superimposed with necrotizing abscesses. The mean size of the wound was 49.6 cm 2 . The mean length of hospital stay was 33.3 days. The mean time to wound healing was 7.9 weeks. The mean follow-up period was 25.9 months. Complications included delayed wound healing (4 cases) and recurrence of the diabetic wounds (2 cases), which were resolved by meticulous wound dressing. @*Conclusion@#STSG remains a good treatment strategy for chronic diabetic wounds of the foot and ankle.

Use of Ultrasonography for Foot and Ankle Sports Injuries / 대한정형외과학회잡지

Sports injuries of the foot and ankle are commonly encountered in clinical practice. Ultrasound is very useful for the diagnosis of such injuries, because it is more economical, readily accessible, and can perform a dynamic study compared to magnetic resonance imaging. This review focused on the sonographic features of common foot and ankle sports injuries.

Origin of Satellite Ganglion Cysts with Effusion in the Flexor Hallucis Longus Tendon Sheath around the Hallux

BACKGROUND: To describe the clinical and magnetic resonance imaging findings of ganglion cysts with effusion in the flexor hallucis longus tendon sheath around the hallux to evaluate their origin. METHODS: Patients with recurrent or painful ganglion cysts around the hallux with effusion in the flexor hallucis longus tendon sheath who underwent surgical treatment at St. Vincent's Hospital from February 2007 to August 2016 were investigated. Surgical indication was a painful or recurrent mass caused by the cystic lesions. Those without effusion of the flexor hallucis longus tendon sheath were excluded. We assessed the clinical and magnetic resonance imaging findings. RESULTS: Magnetic resonance imaging findings in all patients showed several ganglion cysts around the hallux and large fluid accumulations within the flexor hallucis longus tendon sheath. Regarding the location, six ganglion cysts were on the dorsomedial aspect, one on the plantar medial aspect, seven on the plantar lateral aspect, and one in the toe pulp. Ten patients showed joint effusions in both the metatarsophalangeal and interphalangeal joints, two in the metatarsophalangeal joints, and three in the interphalangeal joints. There were communication stalks with a tail shape or abutment between ganglion cysts with surrounding joint effusions. Intraoperatively, connections between ganglion cysts, the synovial cyst of the flexor hallucis longus tendon sheath, and surrounding joints were seen. CONCLUSIONS: Synovial fluid accumulation in the metatarsophalangeal or interphalangeal joint supplies the synovial cyst of the flexor hallucis longus tendon sheath and subsequently ganglion cysts in the hallux. In clinical practice, the surgeon should carefully check surrounding joints with tendon sheaths to prevent recurrence of the ganglion cysts around the hallux.

Subtalar Arthroscopy and Posterior Endoscopy / 대한정형외과학회잡지

The application of arthroscopy is becoming increasingly widespread due to the development of surgical instruments and techniques. Subtalar pathology can cause chronic pain in the hindfoot, but it is often misdiagnosed as a lesion of the adjacent ankle joint, which can lead to delayed diagnosis and treatment. Subtalar arthroscopy and posterior endoscopy are good methods to confirm and treat the posterior pathology of the subtalar joint and posterior ankle joint.

Diagnosis and Treatment of Tarsal Tunnel Syndrome / 대한정형외과학회잡지

Tarsal tunnel syndrome is an entrapment neuropathy of the tibial nerve and its branches within the tarsal tunnel, which usually occurs as a result of a space-occupying lesion, trauma or foot deformity. The typical symptoms are pain and paresthesia of the foot at the dermatome of involved nerve branches, and the diagnosis can be made through careful history taking and physical examination. Treatments include conservative management and surgery. Although the reported results of surgical treatment vary, surgical decompression can yield satisfactory outcomes in cases of tarsal tunnel syndrome with a space-occupying lesion.

Gait Analysis of Symptomatic Flatfoot in Children: An Observational Study

BACKGROUND: Flatfoot deformity is a lever arm disease that incurs kinetic inefficiency during gait. The purpose of this study was to measure the degree of kinetic inefficiency by comparing the gait analysis data of a flatfoot group with a normal control group. METHODS: The patient group consisted of 26 children (21 males and 5 females) with symptomatic flatfoot. They were examined with gait analysis between May 2005 and February 2014. Exclusion criteria were patients with secondary flatfoot caused by neuromuscular disorders, tarsal coalition, vertical talus, or others. Patients' mean age was 9.5 years (range, 7 to 13 years). The gait analysis data of the study group and the normal control group were compared. RESULTS: The mean vertical ground reaction force (GRF) in the push-off phase was 0.99 for the patient group and 1.15 for the control group (p < 0.05). The mean ankle moment in the sagittal plane during the push-off phase was 0.89 for the patient group and 1.27 for the control group (p < 0.05). The mean ankle power in the sagittal plane during the push-off phase was 1.38 for the patient group and 2.52 for the control group (p < 0.05). The aforementioned results show that patients with pes planovalgus had a reduction of moment, power, and GRF in the push-off phase during gait. CONCLUSIONS: Symptomatic flatfeet had a moment inefficiency of 30% and power inefficiency of 45% during gait compared to feet with preserved medial longitudinal arches.

Treatment of Massive Defect in Achilles Tendon with Tendon Allograft: A Case Report / 대한족부족관절학회지

Deep infection of Achilles tendon is one of the serious complications that occur after open repair of the tendon. It sometimes leads to a very large tendon defect during the course of treatment. We report on a case of massive defect in Achilles tendon, which was successfully treated with Achilles tendon allograft and flexor hallucis longus tendon transfer.

Operative Treatment of Hallux Valgus / 대한족부족관절학회지

Hallux valgus, or a 'bunion', is a deformity characterized by lateral deviation of the big toe. Surgery is indicated when conservative treatments have failed to result in improvement of symptoms. Operative techniques include simple bunionectomy, distal soft tissue procedure, phalangeal osteotomy, metatarsal osteotomy (distal, shaft, or proximal), arthrodesis (metatarsophalangeal or tarsometatarsal), or resection arthroplasty. Good results are expected when the selection of operative technique is based on the correct treatment principle.

Operative Treatment of Acquired Adult Flatfoot / 대한족부족관절학회지

Acquired adult flatfoot deformity is characterized by flattening of the medial longitudinal arch and dysfunction of the posteromedial soft tissues, including the posterior tibial tendon. When the non-operative treatment fails to result in improvement of symptoms, surgery should be considered. Operative techniques include flexor digitorum longus tendon transfer, calcaneal medial slide osteotomy, lateral column lengthening, and arthrodesis of the hindfoot. The principle of correcting the deformity while avoiding overcorrection and excessive stiffness is important in achievement of good outcomes in these patients.
