3 ANALYSIS OF THE COMPLICATIONS FOLLOWING OPEN REDUCTION AND INTERNAL FIXATION OF DIAPHYSEAL FRACTURES OF THE HUMERUS

4 Introduction

5 Introduction Fractures of the humeral shaft are relatively common injuries. They represent about 3 % of all fractures. Mechanism of Injury  Direct trauma is the most common especially RTA.  Indirect trauma such as fall on an outstretched hand.  Pathological fractures. Introduction

6 Classification AO classification A = Simple fracture B = Wedge fracture C = Complex fracture Introduction

7 Classification According to the line of fracture Introduction Segmental WedgeSpiral Transverse Oblique

8 Treatment Treatment Non operative treatment: Has a long and well-established history of success with union rate up to 95% Includes: 1. hanging cast: 2. coaptation splint: U shaped slab Introduction

9 Treatment: Non operative treatment: 3. Functional bracing 4. Body Bandage Introduction

10 Treatment Non operative treatment: 5. Abduction humeral splint 6. Skeletal traction Introduction

11 Treatment 1. Fractures with unacceptable alignment 2. Open fractures 3. Segmental fracture 4. Floating elbow 5. Associated vascular injury 6. Pathological fracture 7. Humeral fractures in polytraumatized patients Indications for operative management B. Operative treatment: Introduction

12 Treatment Methods of surgical fixation: 1. Compression plate fixation Advantages: anatomical reduction rigid fixation high union rate avoid shoulder complications Disadvantages: extensive soft tissue exposure radial nerve injury long operative time infection 2. External fixator: B. Operative treatment : Introduction

13 Treatment  3. Intramedullary fixation  Flexible intramedullary nailing  Rigid intramedullary rod fixation B. Operative treatment: Introduction

14 Complications of humeral shaft fracture 1. Neural complications: Radial nerve injury : 8- 11% Introduction

15 Complications of humeral shaft fracture 2. Malunion: >20° of anterior angualtion >30° of varus angulation >3 cm shortening 3. Nonunion: > 6 months 4. Joint stiffness. Introduction

16 AIM OF THE WORK

17 AIM OF THE WORK The aim of the work is to analyse the complications through 1 year following open reduction and internal fixation of diaphyseal fractures of the humerus.

18 PATIENTS

19 Patients The study included 70 patients presented to El-Hadara University Hospital Age: age 21 – 30 2531-4013 41- 50 16>5016 Ranged from 20 to 78 years old with a mean age of 40 years.

20 Gender: There were 43 males and 27 females Patients The right side was affected in 34 patients and the left side was affected in 36 patients Side affected:

22 Methods Methods

23 A full workup including history taking, clinical examination and radiological evaluation as well as laboratory investigations were done Methods

24 Surgical technique:  Anesthesia: Methods The operation was performed under general anaesthesia. All of our patients received intravenous antibiotics prior to the skin incision.

25 Surgical technique: 35 patients were operated through anterolateral approach in supine position with arm on arm board Methods

26 Surgical techniques: 35 patients were operated through posterior approach in lateral position Methods

27

28 Methods of assessment : No pain Full range of motion of shoulder and elbow Good radiological alignment Excellent Activity pain Loss of between 20ºand 40º of shoulder range of motion in a single direction and elbow range of flexion and extension Malunion with an angle more than 10º Fair  Results were assessed according to Stewart and Hundley’s scoring system Methods Constant pain more than 40º Loss of shoulder range of motion in a single direction and elbow range of flexion and extension Non-union or iatrogenic radial nerve palsy Poor Occasional pain Less than 20º loss of shoulder range of motion in a single direction and elbow range of flexion and extension Malunion with an angle less than 10º Good

45 Conclusion

46 1.The use of dynamic compression plate in treatment of midshaft fracture humerus gives excellent results with a low rate of complications. 2.The use of anterolateral approach as surgical approach in (ORIF) of midshaft fracture humerus gives excellent functional outcome and doesn't affect extensor mechanism of elbow. Conclusion

47 3.The anterolateral approach is a safe surgical exposure with low rate of iatrogenic radial nerve injury. In fractures with proximal extension the approach can be extended upward. 4.The use of posterior approach as surgical approach in ORIF of midshaft fracture humerus is indicated in lower third or midshaft fractures of the humerus with distal extensions. But it affects extensor mechanism of the elbow giving some extension deficits. Conclusion
