Forearm Fractures in Singapore

forearm fracture

Orthopaedic surgeons refer to fractures of the forearm as those fractures that occur in the middle section (shaft) of the forearm bones. Fractures that involve the upper end of the forearm are discussed under elbow fractures. Fractures that involve the lower end are discussed under wrist fractures. The forearm has a complex anatomy to serve […]

Physical Findings of Adhesive Capsulitis

The physical examination of patients with adhesive capsulitis reveals a global reduction in range of motion with a marked decrease in glenohumeral translation also present. Examination of the opposite shoulder (if normal) is performed to identify the patient’s expected normal range of motion for comparison. Evaluation for limitation of pure glenohumeral motion (best measured in […]

Evaluation-Physical Examination

The physical examination findings of the athlete depend on the degree of nerve dysfunction and the chronicity of the injury. Athletes presenting early in the process often have an examination that is nonfocal and nonspecific. Patients with chronic problems will demonstrate wasting or atrophy of the involved muscles.

If the nerve is injured or entrapped […]

Evaluation-Physical Examination

Inspect the arm for symmetry with regard to size, color, and skin temperature. Palpation of the cervical spine, the scalenes, and the clavicle can be used to look for structural causes of TOS. A Tinel sign may be elicited over the supraclavicular fossa. A careful neurovascular examination should include strength testing of the muscles and […]

Evaluation-Physical Examination

The athlete with a burner may come off the field shaking his or her arm and hand. If significant neck pain exists, or when neurological symptoms involve two or more extremities, cervical spine precautions should be taken with the athlete until the player is cleared from having a cervical spine injury.

A typical examination of […]

Palpation of the cuboid-metatarsal V joint

The base of the fifth metatarsal bone is gripped between the thumb and index of one hand. The cuboid bone (medial to the metatarsal and distal to the already identified calcaneocuboid joint line) is gripped between the thumb and index finger of the other hand. A translation movement discloses easily the joint line between cuboid […]

Palpation of the calcaneocuboid joint and ligaments

The examiner places the interphaJangeal joint of his thumb on the base of the fifth metacarpal bone and aims in the direction of the midpoint between the two malleoli. The tip of the palpating thumb now lies exactly on the lateral calcaneocuboid ligament. In neutral position the joint line can clearly be ascertained. The ligament […]

Palpation of the posterior talofibular ligament

Place the palpating finger deeply behind the lateral malleolus and search for the lateral and posterior aspects of the talus. A dorsiflexion movement in the ankle makes the taut ligament press against the finger.

Palpation of the anterior talofibular ligament

The index finger is laid on the anterior surface of the lateral malleolus. A combined plantar flexion-inversion movement of the ankle makes the lateral process of the talus more prominent. The ligament is felt as a thin, flat and horizontal structure, pressing against the palpating finger.

Palpation of the sinus tarsi

Starting from the anterior surface of the lateral malleolus and moving anteriorly and medially, the finger falls into a depression – the sinus tarsi. If the finger is left in place and the foot is inverted, the depression excavates and its borders can be better ascertained. Just anterior to the malleolus the lateral process of […]
