Drew Slimmon Peter Brukner Background Case study Lucia is a female, 16 years of age, who plays Sports ankle injuries present commonly in the general netball with the state under 17s netball practice setting. The majority of these injuries are inversion team. She presents with an ankle injury and plantar flexion injuries that result in damage to the sustained at training the previous night.

2 She lateral ligament complex. is on crutches and is nonweight bearing. Objective Examination raises the possibility of a The aim of this article is to review the assessment and fracture, but X-ray is negative. You diagnose management of Sports ankle injuries in the general practice a severe lateral ligament sprain and manage setting. Lucia with ice, a compression bandage and Discussion a backslab initially. She then progresses Assessment of an ankle injury begins with a detailed history through a 6 week rehabilitation program and to determine the severity, mechanism and velocity of the you recommend she wear an ankle brace for injury, what happened immediately after and whether at least 6 months.

3 There is a past history of inadequately rehabilitated ankle injury. Examination involves assessment of weight bearing, inspection, palpation, movement, and application of special examination tests. Plain X-rays may be helpful to exclude a fracture. If the diagnosis is uncertain, consider second The majority of ankle injuries are inversion and plantar line investigations including bone scan, computerised flexion injuries that result in damage to the lateral tomography or magnetic resonance imaging, and referral to a ligament complex (Figure 1).

4 The main ligaments of Sports physician. Manage all lateral ligament complex ankle concern are the anterior talofibular ligament (ATFL), sprains with ice, compression, elevation where possible and the calcaneofibular ligament (CFL), and the anterior analgesia. Severe ligament sprains or rupture benefit from tibiofibular ligament (also called the anterior inferior a brief period of immobilisation. After initial management, tibiofibular ligament or AITFL). The AITFL is the anterior the athlete should complete a 6 week guided rehabilitation component of the syndesmosis complex (Figure 2).

5 A. program. Athletes with moderate to severe lateral ankle thorough history including past history and examination ligament sprains should wear a semirigid or rigid ankle orthosis for at least 6 months following injury. will determine the need for investigations and guide appropriate management. Keywords: ankle ; athletic injuries ; soft tissue injuries History Injury details Severe ligament sprains or ruptures occur with high velocity injuries , such as landing on a player's foot while jumping or running.

6 Simply rolling the ankle on an uneven surface while walking is unlikely to cause a ligament rupture or fracture in the setting of normal bone density and ligament integrity, ie. there is no history of prior ligament damage. Dorsiflexion and eversion injuries can cause damage to the syndesmosis (Figure 2). A syndesmosis injury takes significantly longer to recover than a lateral ligament injury and, if unstable, warrants immediate surgical referral. 18 Australian Family Physician Vol. 39, No. 1/2, January/February 2010.

7 Post injury details Lateral talar tilt test After a ruptured ligament or fracture, athletes are unlikely to be able This is performed by applying an inversion force to the ankle joint at to continue training or playing sport, and may be unable to weight the heel, then assessing the degree of talar tilt. A talar tilt of greater bear (particularly with a fracture). Swelling within minutes or hours than 15 degrees reflects rupture of the ATFL and CFL (Figure 4).3,4. is the result of the bleeding that occurs with a ligament rupture or fracture/dislocation; swelling from synovitis takes longer to develop.

8 Reports of a cracking noise or the feeling that the ankle bent Posterior tibiofibular double cannot differentiate between a fracture, ligament rupture or ligament Anterior tibiofibular ligament ligamentous Posterior Anterior talofibular ligament Past history talofibular ligament Bifurcate ligament The past history provides the practitioner with an understanding of the state of the ankle before the current injury. Inadequate rehabilitation and a subsequently chronically unstable ankle would be expected to take significantly longer to completely rehabilitate.

9 It is important Calcaneofibular ligament Long plantar ligament to clarify the extent of any previous injury and any investigations or treatment. If a rehabilitation program was instituted, the clinician Figure 1. Lateral ankle ligaments should seek details of the type and duration of the program. Appropriate Reproduced from Brukner P, Kahn K.

10 Asking about previous or current use of a semirigid brace or tape may offer insight into the adequacy of past rehabilitation efforts as this is an important component of rehabilitation. Interosseous Examination membrane Examination of the injured ankle includes: Weight bearing if the patient cannot weight bear on the affected Syndesmosis leg for more than four steps unaided, ankle X-rays should be tear ordered (Figure 3)2. Inspection discoloration hematoma and significant swelling are suggestive of ligament rupture or fracture Anterior Palpation pain on palpation of the posterior aspect of the tibiofibular ligament medial and lateral malleolus (both sites are void of ligamentous attachments), the base of the fifth metatarsal and the proximal fibula are suggestive of fracture (Figure 3).
