Basic Sciences Module

Best answer: B .

Explanation:
The structure shown is the exiting nerve root at the L3-4 disk, which is the right L3 root. It supplies motor innervation to the iliopsoas via its contribution to the femoral nerve and sensory innervation to the anteromedial thigh and medial aspect of the lower leg through its dermatome.

Hand Surgery Module

Best answer: D .

Explanation:
Wassel is the most common classification system for thumb polydactyly: I: bifid distal phalanx . II: duplicated distal phalanx . III: bifid proximal phalanx . IV: duplicated proximal phalanx . V: bifid metacarpal . VI: duplicated metacarpal . VII: triphalangism.

Foot & Ankle Module

Best answer: B .

Explanation:
The MRI demonstrates a stress fracture of the second metatarsal. Appropriate initial management includes a period of non-weight bearing, as well as assessment of risk factors for additional stress fractures such as poor nutrition and amenorrhea.

Orthopaedic Trauma Module

Correct Answer: C .

Explanation:
This is a Salter-Harris type II fracture of the distal tibia. The distal tibia is at moderate risk for growth arrest after physeal injury. The average incidence of growth disturbance is 15% for all physeal injuries in this area. The patient’s age and remaining growth also affect the likelihood of a growth arrest causing a significant deformity or leg length discrepancy.

Paediatric Orthopaedics Module

Explanation:

Best answer: B .
The patient’s clinical presentation is consistent with Charcot – Marie – Tooth (CMT) Disease, also known as Hereditary Sensory Motor Neuropathy. The Cavovarus foot is secondary to Peroneus Brevis and Tibialis Anterior weakness. Acetabular Dysplasia is known to occur in association with CMT.

Orthopaedic Oncology & Pathology Module

Best Answer : E .

Explanation:
The radiographs show a radiolucent lesion in the proximal femur. In a patient older than age 40 years, a new painful bone lesion most likely represents metastatic carcinoma or multiple myeloma even if the patient does not have a known history of cancer. The diagnosis must be firmly established and the patient should be staged prior to initiating treatment. Imaging studies should be completed prior to proceeding with a biopsy. This patient should undergo a bone scan to look for other lesions. A CT scan of the chest, abdomen, and pelvis should be performed to look for a primary tumour as well as other sites of metastases. (Lung or kidney would be the most common primary sites for a patient who presents with metastases of unknown origin.) Serum and urine protein electrophoresis should be obtained to look for multiple myeloma.

Spinal Surgery Module

Best answer: C .

Explanation:
The lateral radiograph shows translation and kyphosis at the level of injury. The facets of C4 do not superimpose on each to create a “double sail” sign. This patient has a unilateral facet dislocation. With unilateral facet dislocations, there is usually 3 mm to 4 mm of forward translation and 5° to 7° of angulation.
