2	Technique and Results of Anterior THA
3	Anterior Approach for THR: Technique of Robert Judet Hueter approach (short Smith-Pete) Performed on orthopaedic table
4	Advantages of Anterior THA Supine position Small incision No muscle detachment from bone “Hip deltoid” preserved Improved control of component position and leg length
5	Advantages of Anterior THA No routine postoperative dislocation precautions Applicable to all patients Facilitates bilateral hip replacement

43	November 1996 – April 2005 A consecutive, unselected series of 657 primary THA in 590 patients (67 bilateral) 129 hybrid 528 uncemented
44	"Acetabular components" Acetabular components all uncemented
45	Femoral Stems Cemented: Heritage 40 Versys 1 MS-30 88 Total: 129 Uncemented: Alloclassic 375 Corail 128 Accolade 23 Taperlock 2 Total: 528
46	Age Median 66 years Range 29 - 91
47	"Max BMI 57" Max BMI 57
48	Most Recent 100 Hips Average blood loss: 345 cc Range 150 - 800 cc Average op time: 1.2 hr Range 0.8 – 1.9 hrs
49	"Incision length" Incision length averages 10 cm
50	Post-op Length Discrepancy from Low AP Pelvis Average 3mm Range (-11 to 10) Standard deviation: 4
51	Post-op Acetabular Abduction from Low AP Pelvis Average 41° Standard deviation: 4 Minimum 33° Maximum 49°
52	Post-op Acetabular Anteversion from Low AP Pelvis Average 23° Standard deviation: 5 Minimum 9° Maximum 38°
53	Complications Infection: 1 Femoral nerve palsy: 1 (recovered)
54	Fracture Complications Greater trochanteric fx: 3 Intra-op femoral shaft fx: 2 Intra-op acetabular fx: 1 Ankle fx: 3 Calcar fx: 4
55	Anterior dislocations: 2 • Posterior dislocation: 1 • No recurrent dislocations
56	Revisions Stems: 5 Heritage loosening 1 Versys loosening Cups: 1 HG poly wear 4 Sulzer recall
57	First walked without assistive device Median 8 days Range 0 – 105 days
58	Stopped using assistive device Median 15 days Range 0 – never stopped
59	It is my impression that early pain relief and recovery rate are greatly facilitated.
60	What factors will drive trends in MIS THA? Clinical studies Practicing surgeon preferences Patient preferences
