45 year old lady slips and falls on the ground. She is unable to get up and walk. The X Ray reveals a fracture of the femur at the lesser trochanter.
Two types Extracapsular Intracapsular Extra capsular Trochanteric Subtrochanteric
Trochanteric (Evan’s classification) Stable # configuration – Type A & B Unstable # configuration – Type C & D Type C – lateral cortex is intact Type D – lateral cortex is violated Type E – Reverse obliquity Fractures parallel to neck axis &traverse lat. cortex
Subtrochanteric Three types- Simple, Wedge, Complex All unstable due to relatively small contact area
Intra capsular Classification (Low energy) Fracture site- subcapitus, transcervical, basicervical Inclination of the # - Pauwel’s classification Type I – 30 degree Type II – 50 Type III – 70
Relation of # fragment Garden classification Type I – incomplete & impacted Type II – Complete & undisplaced Type III – Complete & partially displaced (intact post.retinacular ligament) Type IV – completely displaced (disruption of reti.vessels)
Classification (High Enegy) Type I - undisplaced neck # Type II – simple displaced neck # Type III – Comminuted displaced neck # Type IV – FON + # of acetabulum or shaft of the femur Type V – Neck # that occur or recognized during antegrade nailing of shaft
Safe place Reassure the person Have the victim lie flat and rest. Ask for help CPR If there is a wound remove the clothes If there is bleeding apply direct pressure to the wound to stop the bleeding. Cover the wounded area with a clean cloth or dressing. Continue to apply pressure as long as the wound bleeds. Add new dressings over existing ones.
Immobilize the injured area. A splint is a good way to immobilize the affected area, reduce pain and prevent shock. Effective splints can be made. The general rule is to splint a joint above and below the fracture. Or, lightly tape or tie an injured leg to the uninjured one, putting padding between the legs, if possible.
Check the pulse in the limb with the splint. If you cannot find it, the splint is too tight and must be loosened at once. Check for swelling, numbness, tingling or a blue tinge to the skin. Any of these signs indicate the splint is too tight and must be loosened right away to prevent permanent injury Keep her fasting Inform relatives Move to hospital
Prevention Pre-hospital care Hospital care Rehabilitation “Manage the patient, Not the fracture”
A = Airway B = Breathing C = Circulation D = Disability of CNS E = Exposure of the patient F = Foley catheter
At risk in all unconscious patients.
Blood loss is greater than the NOF fracture and trochanteric fracture. Large volume of blood can accumulate in the thigh. Skin: cold, pale,sweating Pulse: rate, volume, rhythm Blood Pressure JVP Adequate fluid resuscitation.
Head injury Examination: Level of consciousness External wounds Pupils- dilated, unequal CT scan of the brain
Damage to cervical spine Suspected in all unconscious and head injured patients. In line bimanual immobilization Semi rigid collar X-ray cervical spine
Generalized bone diseases 1. Paget’s disease of bone 2. Primary hyperparathyroidism 3. Osteomalacia 4. Osteoporosis

1. General Examination 2.Examination of the Hip Joint 3. Special Examination of systems 4. Radiographical Examination
Patient is in pain Unable to stand Limb is shortened and lies in external rotation Skin wounds or obvious deformity
Ecchymosis of the proximal thigh- occasional
Inspection Skin changes- Redness, swelling Shape Position Scars Wasting of gluteal and thigh muscles Palpation Temperature, tenderness over the joint Skin, soft tissue, muscles, bone Movements Voluntary, involuntary, crepitus Flexion- measured with knee bent. Opposite thigh must remain in neutral position. Flex the knee as the hip flexes. Abduction- measured from a line that forms an angle of 90 degrees with a line joining the ASISs. Adduction Rotation in flexion Rotation in extension Extension- attempt to extend the hip with the patient lying in the lateral or prone position
Look for, Shortening in External rotation of the involved extremity Palpation below the ingunum elicits pain Inability to move
1. Circulatory system 2. Neurological Examination 3. Musculoskeletal System
Inspection Palpation Percussion Auscultation
Examination of Associated Injuries Wrist # Head injury Most frequently associated injuries are due to patient’s osteoporosis in other areas of the body. They are sustained at the same time as the trochanteric fracture

X-ray Hip To evaluate the reduction
Management of fracture can be considered as, Operative treatment Non operative treatment Indications for Non operative Treatment An elderly person whose medical condition carries an excessively high risk of mortality from anaesthesia and surgery Non ambulatory patient who has minimal discomfort following fracture
Skeletal traction is the most common method used to control and reduce pain In subtrochanteric fracture most common method to reduce the fracture is by skeletal traction with a transcondylar Steinmann pin 90 degree flexion is used to relax the iliopsoas: correct the flexion and external rotational deformities period of traction ranges from 12 to 16 weeks should be monitored with regular radiological imaging Early removal of skeletal traction may be followed by bracing with a hip spica cast when early callus is seen in x-ray films. Maintenance exercise must be administered regularly to maintain the mobility of joints and muscle strength
In elderly patients, this approach was associated with high complication rates typical problems included decubiti, urinary tract infection, joint contractures, pneumonia, and thromboembolic complications, resulting in a high mortality rate. In addition, fracture healing was generally accompanied by varus deformity and shortening because of the inability of traction to effectively counteract the deforming muscular forces
Surgical stabilization is the standard of care Internal fixation of fractured end is widely performed. Intramedullary nail fixation is the preferred treatment Two methods Open Method Closed Method
possible in fractures with minimal comminution but it demands an extensive dissection weight-bearing may not be possible until the fracture heals disadvantage of the open technique is extensive soft tissue dissection temporarily fixed with reduction forceps or Kirschner wire (K-wire) fixation; then fixed with lag screws plate is fixed proximally to the femoral head and neck for maximal stability
closed reduction and internal fixation Closed reduction is usually performed with the use of a fracture traction table with a transcondylar Steinmann pin fixation can be carried out with percutaneous implant insertion most common implant used is the intramedullary locked nail does not disturb the fracture hematoma minimum soft tissue dissection need to use fluoroscopy and the difficulty in performing distal locking are potential disadvantages
This device is indicated only for very proximal fractures. The sliding of the screw allows medialization of the distal fragment, which reduces bending moment on fracture and implant
Hence this was pathological fracture we have to find the cause and treat for that. metastatic tumours are the most common types of tumour deposits in this region So other metastatic sites should also be investigated before definitive fixation of the fracture is performed. In the case of primary, investigate for secondaries and follow chemotherapy / Radiation therapy
Pre operative measures a)Assessment of the patient Cormobid factors Surgical fitness Risk for anesthesia b)Pre operative templating - for proximal comminution the use of a fixed angle device with the proper blade and compression screw length
When an intramedullary device is chosen, templating for length, canal diameter is necessary for proper planning. c)Measurements Normal side femur length
Surgery main techniques: external fixation open reduction and internal fixation a)Extra medullary implants b)Intra medullary implants
Extra medullary devices 1.)Sliding compression screw plate 2.)Dynamic hip screw(DHS) e.g:-DCS Indications:- Fractures with stable configurations Unstable fractures with an intact lateral cortex
Intra medulary devices 1)Intra medullary hip screw(IMHS) Cephalomedullary nails Reconstruction nails(centromedullary) Indications:- Shorter nail-If fracture line doesn’t extend more than 1 to 2cm distal to lesser trochanter Longer nail-unstable fractures
External fixation- Rarely used but is indicated in severe open fractures. For most patients, external fixation is temporary, and conversion to internal fixation can be made if and when the soft tissues have healed sufficiently.
Post operative period. 1.)Following intramedullary nailing if the bone quality and cortical contact is adequate, 50% partial weight bearing can be allowed immediately. With less stability, patients can perform touchdown weight bearing. Following OR and plate fixation, minimal protected weight bearing can begin immediately but is advanced slowly beginning approximately 4 weeks after surgery, with full weight bearing anticipated at 8-12 weeks. Elderly patients may have difficulty with compliance with weight bearing restrictions.
2.) Check for proper union 3.) Prevent infections 4.) Wound care 5.) Nutrition- high protein diet
Acute complications 1. Damage to nerves and blood vessels 2. Haemorrhage 3. Other soft tissue damage Long term complications 1. Failure of fixation -screws may cut out of the bone if reduction is poor or if the fixation device is incorrectly positioned. Reduction and fixation may have to be re-done.
2. Malunion - only complication that is frequent -may occur through bending or breakage of a nail plate or simply through compression of the soft cancellous bone with metal. -causes union with a slightly reduced neck-shaft angle- coxa vara
- If neglected, I. May unite with marked lateral rotation of the shaft. II. May develop severe coxa vera associated with shortenig. Treatment 1. In most cases, can be accepted without treatment. 2. In severe deformities, -the bone is divided in the trochanteric region and the fragments are secured in the correct position by a compressive screw plate or other appropriate device(as in a fresh fracture.
complications due to treatments 1. casts - pressure ulcers -thermal burns -thrombophlebitis 2. Internal fixation - infections - neurological and vascular injury -thromboembolic events -avascular necrosis -posttraumatic arthritis
Close follow-up is required following fixation 50% PWB can be allowed immediately Wound is checked for proper healing 7-14 days post operatively DKA
Patient should have monthly clinical evaluations and radiographs to monitor healing. Quadriceps rehab to be started within 02 weeks post operatively Most patients will have significant disability for 4-6 months DKA
