Lower spinal nerves are commonly injured by slipped discs:
The disc herniates, and its centre - nucleus pulposus crushes the spinal nerves on the affected side This affects supply to stablising muscles such as gluteus medius and minimis To perform the test, ask the patient to raise one leg. A positive test presents as the raised leg sags down, demonstrating weakness in the abductor muscles on the other side "Sound goes down" |

|
Sciatic nerve:
Describe the surface anatomy of the origin of the sciatic nerve and a safe area for administering a gluteal injection? |
The sciatic nerve enters the gluteal region between the PSIS and the ischial tuberosity, and leaves between the ischial tuberosity and the greater trochanter of the femur.
Injections are best given by placing your index finger on the ASIS and middle finger on the iliac tuberosity, and injecting between the two. If administered incorrectly, the patient will report tingling/pain and you may observe 'drop foot'. |
|

|
Semitendinosus is the most superficial, medial hamstring.
Semimembranosus lies deep and medial Biceps lies more lateral (long head from ischial tuberosity, short head from lateral femur) Blood supply to all is Profunda Femoris. The oblique popliteal ligament is from semimembranosus and gives support to the back of the knee. |

|
What is the 'unhappy triad'?
|
ACL tear caused by a force exerted lateral to medial on an already weight bearing and extended knee
This in turn also ruptures the medial collateral as this is outside the joint and is already stretched in extension. The medial collateral inserts onto the medial meniscus, so this also ruptures. |
|
What are the two most important bursae in the knee?
|
The supra- and infrapatellar.
|
|
Where is the ankle joint more stable and why?
|
In dorsiflexion, due to the shape of the articular surface of the Talus - wider at the front - it is less stable in plantarflexion.

|
What two factors are said to influence poor communication in health care consultations, which study represents these findings, and what is the result?
|
Message and relationship:
Message - insufficient info, complexity, poor understanding and lack of organisation of info given. Leads to poor understanding, recall and satisfaction, ultimately to non-adherence Relationship - insufficient interest, lack of empathy and involvement in decision making, failure to acknowledge ICE. Leads to low satisfaction, credibility, poor recall and non-adherence |
