Gastrocnemius Recession in the Setting of Metatarsalgia: The Baumann Procedure

Proximal Medial Gastrocnemius Recession for Recalcitrant Plantar Fasciitis

BACKGROUND

Recalcitrant plantar fasciitis (RPF) is characterized by its unresponsiveness to conservative treatments, and its surgical management remains controversial. Although there is some evidence to suggest that gastrocnemius recession can be an effective treatment for RPF, no large series of patients with mid- to long-term follow-up has been published. The objective of this study was to compare physical performance, as measured by the Foot and Ankle Ability Measure activities of daily living score (FAAM-ADL), and pain levels before and 1 year after undergoing proximal medial gastrocnemius recession (PMGR) as a treatment for RPF. Additionally, we aimed to assess this cohort of patients in the mid- to long-term follow-up.

METHODS

This retrospective cohort study included 167 patients who underwent PMGR to address RPF between 2009 and 2021. Patients were examined with the FAAM ADL, visual analog scale (VAS) and satisfaction scores at baseline, 1 year, and at the end of follow-up. Other variables recorded were weight, duration of symptoms until surgery, time between surgery to substantial clinical improvement, calf power and Silfverskiold test, and postoperative complications.

RESULTS

We observed that before surgery patients had an FAAM-ADL score of 22.5 (SD 11.1) and a VAS score of 8.6 (SD 9.3). One year after surgery, patients had an FAAM-ADL score of 89 (SD 17) and VAS of 1.33 (SD 2) (P < .01). We also observed that the FAAM-ADL score in the long-term follow-up (>12.5 years) group had a median of 86.4 (SD 22.6), the VAS score was 1.90 (SD 2.84), and the patient satisfaction score had a median of 1 (interquartile range 0-1). Regarding complications, we observed 1 lateral gastrocnemius recession and 1 sural nerve neuritis.

CONCLUSIONS

Our study provides substantial evidence supporting the use of PMGR as an effective treatment for RPF. The long-term follow-up and large sample size of our series contribute to the existing literature on this topic.

Continuous Wear of Night and Day Orthosis Is a Key Factor for Improvement of Fixed Equinus Deformity after the Transverse Vulpius Procedure

Background: Equinus foot deformity is secondary to either spasticity or contracture of the gastrocnemius–soleus complex. The plantar flexion is basically treated conservatively; several different surgical methods have been discussed. This paper focuses on the improvement of passive ankle dorsiflexion after a transverse Vulpius procedure in equinus foot deformity. Additionally, the influence of consequent postoperative wear of orthosis on the improvement of ankle range of motion was investigated. Methods: In total, 41 patients with neuromuscular impairment and 59 equinus feet deformities were surgically treated by using a transverse Vulpius procedure. A total of 19 female patients and 22 male patients with a mean age at surgery of 10.18 years (2 to 31) were included. Mean follow-up took place 12.26 ± 7.95 months after surgery. Passive ankle dorsiflexion was measured and subjective patients’ satisfaction was assessed. Results: Range of motion, measured as the maximum of passive ankle joint dorsiflexion, improved significantly from −8° ± 5.9° to 11.1° ± 6.7° directly after surgery to 16.2° ± 10.7° at follow-up. The improvement of passive ankle dorsiflexion was significantly associated with the continuous wearing of night and day orthosis (p = 0.0045). Patient subjective satisfaction was very high. Conclusion: A transverse Vulpius procedure for aponeurotic gastrocnemius and soleus muscle lengthening of equinus foot deformity resulted in a significant improvement of passive ankle dorsiflexion. Positive surgical results correlated to a continuous use of orthotic devices.

Ankle dorsiflexion after isolated medial versus complete proximal gastrocnemius recession: A cadaveric study

PURPOSE

Gastrocnemius recession has been described in the treatment of gastrocnemius contracture. The aims of this study were: (1) to assess the change in ankle dorsiflexion after isolated medial gastrocnemius recession performed according to L.S. Barouk's technique; (2) to compare ankle dorsiflexion after isolated medial head with complete proximal gastrocnemius recession.

METHODS

A cadaveric study was performed on 15 lower limb adult specimens. Isolated medial gastrocnemius head recession was initially performed, followed by an additional recession of the lateral gastrocnemius head. Ankle dorsiflexion torque was applied with 2 and 4 kg forces on second metatarsal head. Ankle dorsiflexion was measured with the knee both in extension and at 90° of flexion and values were recorded before surgery (T0), after medial head recession (T1) and after both heads recession (T2). Normality of data was assessed using the Shapiro-Wilk test, then measurements were compared in the three conditions with appropriate statistical tests.

RESULTS

After isolated medial gastrocnemius recession (Δ = T1-T0), ankle dorsiflexion assessed with the knee in extension significantly increased by 5° ± 3 (range, -2 to 10) with a 2-kg torque (p = 0.02) and by 4.5° ± 3 (range, -4 to 10) with a 4-kg torque (p = 0.04). No significant difference was observed with the knee flexed at 90° (p > 0.05 for all measurements). After both gastrocnemius heads recession (Δ = T2-T1), although a further increase in dorsiflexion was noticed, statistical significance was not reached neither with the knee in extension nor at 90° of flexion (p > 0.05 for all measurements).

CONCLUSION

In this study, isolated medial gastrocnemius head recession performed according to LS Barouk's technique was effective in improving ankle dorsiflexion, whereas the additional release of the lateral head did not produce any significant change.
