ABSTRACT
BACKGROUND: Lateral column lengthening is used to correct abduction deformity at the midfoot and improve talar head coverage in patients with flatfoot deformity. It was our hypothesis that following a stepcut lengthening calcaneal osteotomy (SLCO), patients would have adequate correction of the deformity, a high union rate of the osteotomy, and improvement in clinical outcome scores. METHODS: We retrospectively reviewed 37 consecutive patients who underwent SLCO for the treatment of stage IIB flatfoot deformity with a minimum 2-year follow-up. Deformity correction was assessed using preoperative and postoperative weight-bearing radiographs. Healing of the osteotomy was assessed by computed tomography. Clinical outcomes included the FAOS and SF-36 questionnaires. The Wilcoxon signed-rank test was used to compare clinical outcome scores. An alpha level of .05 was deemed statistically significant. RESULTS: Healing of the osteotomy occurred at a mean of 7.7 weeks postoperatively. The talonavicular (TN) coverage angle improved from 34.0 to 8.8 (P < .001), the percentage of TN uncoverage improved from 40.9% to 17.7% (P < .001), and the TN incongruency angle improved from 68.1 to 8.7 (P < .001). In addition, there was an improvement in FAOS pain (P < .001), daily activities (P < .001), sport activities (P = .006), and quality of life scores (P < .001). Overall SF-36 scores also showed improvement postoperatively (P < .001). There was no incidence of delayed union, nonunion, or graft collapse. CONCLUSION: Following SLCO, patients demonstrated excellent healing, good correction of the deformity, and improvement in clinical outcomes scores. The SLCO is an alternative to the Evans osteotomy for lateral column lengthening. LEVEL OF EVIDENCE: Level IV, retrospective case review.

BACKGROUND: The purpose of this study was to evaluate the cost and benefit of routinely submitting hammertoe specimens for histopathological examination. We hypothesized that such examination rarely shows a new diagnosis and seldom alters postoperative care. MATERIALS AND METHODS: Three hundred and fourteen proximal interphalangeal (PIP) joint and 37 extensor tendon specimens from 187 consecutive hammertoe correction surgeries were submitted by 2 surgeons for histopathological examination between January 2009 and December 2011. Each patient's chart was reviewed to determine whether the histopathological examination revealed a diagnosis other than degenerative joint or degenerative tendon and whether subsequent patient management was altered. The total reimbursements for professional charges were calculated using the average reimbursement from common insurance providers for two Current Procedural Terminology (CPT) codes: 88304 (soft tissue examination) and 88311 (decalcification). RESULTS: Almost all of the specimens were diagnosed as degenerative: 97.5% (307/314) of the PIP specimens and all (37/37) of the tendon specimens. Seven PIP specimens (2.2%, 7/314) from 5 patients (2.7%, 5/187) and no tendon specimens had other diagnoses. These diagnoses were rheumatoid arthritis (5/314, 1.6%), osteomyelitis (1/314, 0.3%), and pigmented villonodular synovitis (PVNS) (1/314, 0.3%). Only the PVNS was a new diagnosis. A total of $56,750 was spent to determine 1 new diagnosis. CONCLUSION: The routine submission of hammertoe specimens for pathological evaluation was not cost-efficient. Our analysis showed that new diagnoses were rarely found and patient management was not affected.
