UNASSIGNED: Tuberculous (TB) osteomyelitis of the foot is a rare entity, often leading to diagnostic challenges due to its atypical presentation and similarity to other foot pathologies.
UNASSIGNED: A 19-year-old male presented with persistent pain and discharge in the left foot for 9 months. Despite previous incision and drainage, the condition progressed. Clinical examination revealed a 1 × 1 cm swelling with indurated margins and a discharging sinus. Diagnostic imaging suggested osteomyelitis, confirmed as TB in nature through histopathological examination, revealing caseous necrosis and langerhans giant cells.
UNASSIGNED: This case illustrates the importance of considering TB osteomyelitis in differential diagnoses of chronic foot lesions and highlights the effectiveness of combined surgical and medical management.

Tuberculosis affecting the smaller bones of the foot is relatively infrequent. There is a paucity of data related to the tubercular involvement of cuboid and metatarsal bones. Diagnosis is challenging, especially in the absence of pulmonary involvement, a history of trauma, and contact with tuberculosis. We present a rare case of primary tuberculosis of the cuboid and fifth metatarsal without pulmonary involvement. The patient was started on anti-tubercular chemotherapy. A detailed literature search revealed that no such case with concomitant involvement of the cuboid and fifth metatarsal without pulmonary seeding has ever been reported.

UNASSIGNED: Isolated osteomyelitis of the cuboid is a rare entity with very few case reports worldwide. A variety of treatment methods are described for these lesions, both single-stage and two staged and ranges from simple curettage to bone grafting and arthrodesis.
UNASSIGNED: We present a series of two cases of chronic osteomyelitis in young adults due to puncture wound over the lateral foot. Both patients presented with purulent discharge from sinus over lateral foot. There was no involvement of adjoining bones in them. Culture yielded Staphylococcus aureus and Pseudomonas aeruginosa. Both patients were treated with adequate curetting, saucerization with cancellous bone grafting in one of the cases. Both wounds healed uneventfully with good ankle and hindfoot function.
UNASSIGNED: The cuboid is a rare site of chronic osteomyelitis due to punture wounds with foreign bodies, especially in rural population. With meticulous curettage and bone grafting, the infection can be eradicated reliably and usually with good residual function.

Cuboid dislocations are rare midfoot injuries that usually occur in the setting of high-energy trauma. Diagnosis can be challenging and optimal treatment remains unknown. This case report and review aims to summarize the recent literature on this topic.

Osteochondromas are common benign exostoses with <1% of pedal occurrences. Several cases of osteochondromas have been previously reported in the foot and ankle but none from the cuboid. In the present study, we report a case of osteochondroma originating from the cuboid in a 29-year-old male patient. The patient presented with an aching and shooting pain to his left foot that had progressed during the course of 3 years. Originally diagnosed as a fibroma, the patient had undergone cortisone injections that did not help with his symptoms. Radiographic and magnetic resonance imaging revealed an osteochondroma to the patient\'s left cuboid. Surgical removal of the tumor confirmed the diagnosis. The patient had an uneventful postoperative recovery and had no recurrence after 1.5 years of follow-up. In conclusion, although osteochondromas are rare in the foot and ankle and most are benign, they can result in many symptoms and can impair patients\' quality of life, such as occurred in our patient. Recommendations for surgical excision should be determined on a case-by-case basis.

BACKGROUND: Isolated cuboid dislocations are rare injuries Jacobson (1990). It is clinically significant and important in surgical education, as it is an injury and a source of lateral foot pain that can be misdiagnosed at the time of initial presentation and may be difficult to identify clinically or with imaging Drummond and Hastings (1969).
METHODS: We present a case report in a 33year old rugby player, who was injured during a match after a tackle. The patient had ongoing concerns that he was not recovering following initial discharge, as he was unable to weight bear since his initial presentation to the Emergency Department (E.D.), and he had ongoing lateral foot pain.
CONCLUSIONS: Important clinical findings include lateral foot pain, a palpable gap at the cuboid level and difficulty weight-bearing. Closed reduction is usually difficult as it can be blocked mechanically by the extensor digitorum brevis muscle or peroneus longus tendon Dobbs et al. (1969). Initial X-Rays may be inconclusive with this presentation. CT scanning is indicated if suspicion for pathology is high. Open reduction and internal fixation with Kirschner wires are usually necessary for isolated cuboid dislocations.
CONCLUSIONS: Our take home message from this case report is that cuboid dislocations are rare injuries and are important to be aware of in reviewing X-rays in the E.D. Particularly in patients with inversion and plantar flexion type injuries to their foot and ankle joint, with an inability to weight bear and lateral midfoot pain following their injury.

OBJECTIVE: Although infrequent, a fracture of the cuboid can lead to significant disruption of the integrity of the midfoot and its function. The purpose of this study was to classify the pattern of fractures of the cuboid, relate them to the mechanism of injury and suggest methods of managing them.
METHODS: We performed a retrospective review of patients with radiologically reported cuboid fractures. Fractures were grouped according to commonly occurring patterns of injury. A total of 192 fractures in 188 patients were included. They were classified into five patterns of injury.
RESULTS: Type 1 fractures (93 fractures, 48.4%) are simple avulsion injuries involving the capsule of the calcaneo-cuboid joint. Type 2 fractures (25 fractures, 13%) are isolated extra-articular injuries involving the body of the cuboid. Type 3 injuries (13 factures, 6.8%) are intra-articular fractures solely within the body of the cuboid. Type 4 fractures (35 fractures, 18.2%) are associated with disruption of the midfoot and tarsometatarsal injuries. Type 5 fractures (26 fractures, 13.5%) occur in conjunction with disruption of the mid-tarsal joint and either crushing of the lateral column alone or of both medial and lateral columns. Fractures with significant articular disruption or with loss of length of the lateral column underwent fixation. This involved either internal fixation to restore the anatomy of the cuboid and/or restoration of the length of the columns with bridging constructs using internal or external fixation.
CONCLUSIONS: A classification system for fractures of the cuboid is proposed in relation to the mechanism of injury. The treatment of these fractures is described. Cite this article: Bone Joint J 2016;98-B:1003-8.

BACKGROUND: Brodie\'s abscess of cuboid bone is one of the rarest diagnosis in children which most often is hematogenous in origin. Although Streptococcus pyogenes has been uncommonly implicated as causative organism in other bones, it is not yet reported in the cuboid.
METHODS: We report the case of 14-year-old boy who presented with a lytic lesion in the cuboid bone. It was preceded by a penetrating injury with a small iron nail. He was treated with simple curettage without the addition of bone graft. Frank pus present in the cavity in the cuboid bone grew S. pyogenes on bacterial culture. Symptoms resolved after 6 weeks of antibiotics, however, complete radiological healing was obtained after 9 months.
CONCLUSIONS: Although very rare, S. pyogenes associated Brodie\'s abscess should strongly be suspected in a posttraumatic lytic lesion in the cuboid bone and bone grafting is not always required for bone healing even in presence of large pus-filled cavity.

We describe a rare case of a nonosseous coalition of the lateral cuneocuboid joint with peroneal spasm that we successfully treated with resection. A 60-year-old female had been experiencing constant pain in her right foot, particularly when walking and going up and down stairs. The pain had been present for approximately 1 year after she had experienced a minor injury. Her right ankle showed plantar flexion restrictions (right 20° and left 40°) and was held in an antalgic valgus position. Sudden passive plantar flexion produced pain behind the lateral malleolus of the right ankle. Tenderness was detected in the right peroneus brevis tendon and the right sinus tarsi. On plain radiographs, the oblique view showed an irregularity in the articular surface of the lateral cuneocuboid joint in both feet. On computed tomography images, there was no osseous continuation in the lateral cuneocuboid joint, indicative of a nonosseous bridge between the lateral cuneiform and the cuboid. The nonosseous coalition between the lateral cuneiform and the cuboid was resected and the trabecular surfaces and cortical margins covered with a thin film of bone wax. The patient\'s recovery was unremarkable, and 1 year after surgery, she was able to walk without pain and was able to perform her usual activities and job.

We describe a rare case of intraosseous Schwannoma in the foot involving the tarsal navicular, cuboid, all 3 cuneiforms, and the second and third metatarsal bases in a 50-year-old female. Radiographs revealed a large, well-defined osteolytic lesion with endosteal scalloping and trabeculated contours at the margins. Intralesional excision, allograft bone implantation, and Kirschner wire fixation were performed. The histologic and immunohistochemical studies confirmed the diagnosis of Schwannoma. The distinctive radiographic features might have been the result of tumor spreading within the nutrient canals of the bones and direct compression of bone as the tumor enlarged. At the 18-month follow-up point, the patient had recovered well without recurrence. Intralesional excision produced a good functional outcome; however, extensive fusion surgery is recommended.
