| Abstract: | BackgroundThere has been heightened interest in the effect of osteoanabolic agents on acceleration of fracture healing.ObjectivesThe purpose of this study was to identify whether short-term daily teriparatide prescribed for osteoporosis treatment would improve postoperative outcomes including clinical scores, radiographic healing, and complication rates.MethodsBetween 2014 and 2017, we retrospectively assessed 112 patients who underwent closed reduction and internal fixation with proximal femoral nail (PFN) for unstable intertrochanteric fractures. In 60 of 112 patients, patients were treated with a PFN alone (group I). These patients were compared with 52 patients for whom the same device was used and a daily subcutaneous injection of teriparatide (1–34 PTH, Forsteo®) was prescribed postoperatively (group II). Teriparatide was administered by nurses during a hospital stay and then self-injection was monitored by follow-up visits to the outpatient clinic after discharge. Questionnaire surveys were conducted and patients completed a self-report Harris hip score (HHS) and visual analog scale (VAS) scores.ResultsTeriparatide therapy significantly increased HHS (p = 0.02) and decreased VAS pain scores (p = 0.008). The mean time to fracture healing post-operatively was 14.8 weeks (SD 7.1) and 12.1 weeks (SD 6.4) in group I and II, respectively (p = 0.002). The frequency of patients reporting postoperative complications was also markedly reduced in the teriparatide-treated groups (p = 0.028).ConclusionsShort-term daily teriparatide used for osteoporosis treatment improved radiographic fracture healing of a hip fracture and reduced complication rates. However, because of the limited power of the study, additional randomized placebo-controlled trials are needed to determine the potential benefit of PTH as an adjunct to enhance fracture healing and its efficacy in broader populations with varying comorbidities and fracture types. |
