1 Functional Outcome Following First Metatarsalphalangeal Arthrodesis
27th Annual AOFAS Summer Meeting July 14, 2011 Functional Outcome Following First Metatarsalphalangeal Arthrodesis

3 Introduction First Metatarsophalangeal Joint (MTPJ) Arthrodesis offers reliable pain relief Many accepted techniques Stigma due to perceived functional limitation

4 Introduction Good functional outcomes described One technique
Single surgeon Homogeneous patient population

5 Our Study Review functional outcomes after first MTPJ arthrodesis
Multiple surgeons Different fixation techniques Heterogeneous population

6 Hypothesis Arthrodesis for the treatment of severe degeneration of the first MTPJ yields good functional outcomes regardless of fixation technique. Principles of arthrodesis upheld

7 Methods HSS Dept of Foot/Ankle Surgery patient database CPT code
Five different surgeons

8 Methods Pre/Postoperative FAOS, SF-12/36, activity/shoe wear specific questionnaire Brodsky et al FAI 2005 Radiographic evaluation

9 Methods Subgroup analysis Arthrodesis technique Previous surgery
Cross screws versus Plate/lag screw Previous surgery Concomitant procedure

10 Inclusion Failed conservative treatment Minimum 1-year follow-up

11 Exclusion Concomitant lesser metatarsal head resections
Age less than 18

12 Demographics 51 patients (55 feet) M:F Average f/u 32 months (16-73)
Mean age 58.9 (42-74) M:F 11:44 Average f/u 32 months (16-73) 67% Hallux Rigidus

13 Previous Procedures 22 patients

14 Fixation Technique Plate/lag screw Cross screw 32 Patients (34 Feet)
Isolated procedure

15 Concomitant Procedures

16 Results Preop Postop p-value SF score 69.9 (26.5-93) 79.5 (32.5-98.1)
0.0017 Sport* 58.2 (0-100) 77.6 (0-100) 0.0002 QOL* 38.2 (0-75) 75.2 ( ) <0.0001 Pain* 61.7 (25-100) 90.7 ( ) Symptoms* 61.6 ( ) 86.6 ( ) Activity* 75.3 (25-100) 95.8 ( ) VAS (Pain) 5.5 (2-9) 2.5 (0-10) *FAOS

17 Results 54% Denied shoe-wear limitations
89% Satisfied/highly satisfied

18 Functional Outcomes

19 Functional Outcomes

20 Radiographic Evaluation
82% Union rate Plate/screw Cross screw p Value Union 93% 62% 0.021 Satisfaction 85% 95% ROH 14% 4% screw younger than plate, equivalent outcome scores, of those not satisfied the majority c/o symptomatic plate/screw and c/o shoewear limitations.

21 Solitary Procedure Equivalent outcome scores Similar union rate
sol younger than mult, no difference in union rate, even b/w construct groups

22 Prior Procedure Equivalent outcome scores Union rate 90% vs 68%

23 Limitations Lack of standardization Concomitant procedures
Postoperative protocol Technique Concomitant procedures calc bone graft 75% plate/screw 57% cross screw

24 Discussion Good functional results Rarely limits daily activities
In-line athletics Concomitant/Previous procedures

25 Discussion Union rate Satisfaction rate Shoe wear limitations
Plate/screw vs Cross screw Satisfaction rate Shoe wear limitations Difference in union rates did not affect outcome scores. difference in satisfaction b/w plate and cross 85% vs 95%. most unsatisfied pts c/o shoe wear limitations. half had complication (prominent hardware)
