“…During insertion of the M1 to M2 screw, the surgeon must check if there is no interposed tissue, avoiding the neurovascular bundle. 21 Verification of sagittal alignment of the M1 is performed clinically in the frontal view of the foot. M1 head must be at the same level or slightly lower than the fifth metatarsal head (Figure 7).…”

The modified Lapidus procedure (MLP), which consists of fusion between the first metatarsal (M1) and medial cuneiform, has been widely performed with satisfactory clinical outcomes, but it has a variable nonunion rate ranging between 4% and 10% and loss of correction in up to 5.8% of the cases. Excessive motion around the site of tarsometatarsal arthrodesis, specially at the intercuneiform joint, is probably the reason. The original Lapidus procedure (OLP), which includes fusion of the M1 to second metatarsal (M2), may be beneficial in preventing nonunion and recurrence. The objective of this study was to describe intraoperative technical tips in the OLP to improve M1 to M2 fusion, which may prevent complications. Since the Lapidus procedure continues to gain popularity, it is the authors opinion that the OLP requires special attention because it is a more technically demanding surgery compared to the MLP.

“…Some authors advocate for fixation placement in an intermetatasal fashion between the first and second metatarsals 11,12 . An understanding of the positional anatomy could guide fixation placement 13 . Iatrogenic injury to the D-PL artery has been reported in the literature in one case involving first metatarsocuneiform joint arthrodesis with resultant pseudoaneurysm formation 3 .…”

BACKGROUND: The deep plantar (D-PL) artery originates from the dorsalis pedis artery in the proximal first intermetatarsal space, an area where many procedures are performed to address deformity, traumatic injury and infection. The potential risk to injury of the D-PL artery is concerning. The D-PL artery provides vascular contribution to the base of the first metatarsal and forms the D-PL arterial arch with the lateral plantar artery. METHODS: In an effort to improve our understanding of the positional relationship of the D-PL artery to the first metatarsal, dissections were performed on 43 embalmed cadaver feet to measure the location of the D-PL artery with respect to the base of the first metatarsal. Images of the dissected specimens were digitally acquired and saved for measurement using in-house written software. The mean, standard deviation and 95% confidence intervals were calculated for all measurement parameters. RESULTS: We found that the origin of the D-PL artery was located at 11.5 ± 3.9 mm (95% CI: 4.5 - 24.7 mm) distal to the first metatarsal base and 18.6% ± 6.5% (95% CI: 8.1% to 43.4%) its length in reference to the proximal base. The average inter-rater reliability across all measurements was 0.945. CONCLUSIONS: Our study helps to clarify the anatomic location of the D-PL artery by providing parameters to aid the surgeon when performing procedures in the proximal first intermetatarsal space. Care must be taken when performing procedures in the region to avoid unintended vascular injury to the D-PL artery.
