Background: Success rates for surgical management of chronic exertional compartment syndrome (CECS) are historically lower with release of the deep posterior compartment compared with isolated anterolateral releases. At our institution, when a deep posterior compartment release is performed, we routinely examine for a separate posterior tibial muscle osseofascial sheath and release it if present. Purpose: Within the context of this surgical approach, the aim of the current study was to compare long-term patient satisfaction and activity levels in patients who underwent 2-compartment fasciotomy versus a modified 4-compartment fasciotomy for CECS. Study Design: Cohort study; Level of evidence, 3. Methods: Patients treated with fasciotomy for lower extremity CECS from 2007 to 2017 were retrospectively identified. In all patients in whom a 4-compartment fasciotomy was indicated, the tibialis posterior muscle was examined for a separate osseofascial sheath, which was released when present. Patients completed a series of validated patient-reported outcome (PRO) surveys, including the Marx activity score, Tegner activity score, 12-Item Short Form Health Survey, and Likert score for patient satisfaction. Results: Of the 48 patients who were included in this study, 34 (71%) patients with a total of 52 operative limbs responded and completed PRO surveys. The mean follow-up for the entire cohort was 5.5 ± 2.6 years. Of the 34 patients, 23 (68%) underwent 2-compartment fasciotomy and 11 (32%) underwent 4-compartment fasciotomy. Among the patients in the 4-compartment fasciotomy group, 7 (64%) were found to have a fifth compartment. No significant difference was found in any of the validated PRO measures between patients who had a 2- versus 4-compartment fasciotomy or those who underwent 4-compartment fasciotomy with or without a present fifth compartment. At a mean 5.5-year follow-up, 74% of patients who underwent a 2-compartment release reported good or excellent outcomes compared with 82% of patients who underwent our modified 4-compartment release. Conclusion: The current study, which included the longest follow-up on CECS patients in the literature, demonstrated that the addition of a release of the posterior tibial muscle fascia led to no significant difference in PRO measures between patients who underwent a 2- versus 4-compartment fasciotomy, when historically the 2-compartment fasciotomy group has had higher success rates.
Case:
A 65-year-old man with scoliosis underwent posterior spinal fusion with instrumentation from T4 to pelvis and subsequently developed wound complications eventually diagnosed to be secondary to postoperative pyoderma gangrenosum (PPG). Once immunosuppressant medications were initiated, the wound gradually improved and went on to heal after a prolonged period of wound care.
Conclusion:
Postoperative PG is a challenging problem for the orthopaedic surgeon; a multidisciplinary approach is beneficial. Early recognition of the diagnosis is imperative to limit morbidity because debridements for a presumed infectious etiology are likely to exacerbate the disease through a process called pathergy.
