RESUMO
CASE: We present a case of an anteroposterior compression (APC) type pelvic ring injury that occurred after chiropractic manipulation in a patient with a history of quadriplegia. Emergent surgical stabilization was undertaken, and he had an excellent outcome with no complications at 3.5-year follow-up. CONCLUSION: APC type pelvic ring injuries usually occur to high-energy mechanisms. We describe a case of a patient with quadriplegia and osteopenia that suffered a pelvic ring injury because of a unique mechanism. Practitioners performing pelvic manipulation should be aware of this type of injury in at-risk patients.

INTRODUCTION: Intertrochanteric femoral fractures are common orthopaedic injuries accounting for nearly 30% of all fracture-related hospitalizations. Because many factors predictive of failure are related to technical aspects of the surgery, the purpose of this study was to compare radiographic parameters after fixation, comparing fellowship-trained orthopaedic trauma surgeons with surgeons who did not complete an orthopaedic trauma fellowship. METHODS: We initiated a search for CPT code 27245 across our hospital network to identify 100 consecutive patients treated by five fellowship-trained orthopaedic traumatologists and 100 consecutive patients treated by community surgeons. Patients were then stratified based on their surgeon's subspecialty training (trauma vs community). Primary outcome variables were neck-shaft angle (NSA), a comparison of the repaired NSA with the uninjured side, tip-apex distance, and reduction quality. RESULTS: One hundred patients were included in each group. The mean age in the community group was 77 years compared with 79 years in the trauma group. The mean tip-apex distance for the trauma group was 10 mm compared with 21 mm for the community group ( P < 0.001). The mean postoperative NSA for the trauma group was 133° compared with 127° for the community group ( P < 0.001). The mean difference of the NSA of the repaired side compared with the uninjured side was 2.5° of valgus in the trauma group compared with 5° of varus for the community group ( P < 0.001). There were 93 good reductions in the trauma group compared with 19 in the community group ( P < 0.001). There were 0 poor reductions in the trauma group and 49 in the community group ( P < 0.001). DISCUSSION: Overall, we have shown that fellowship-trained orthopaedic trauma surgeons achieve better reductions when treating intertrochanteric femur fractures with intramedullary nails. Orthopaedic residency training should emphasize teaching proper techniques and acceptable parameters for reduction and implant placement when treating geriatric intertrochanteric femur fractures.

INTRODUCTION: Patellar and quadriceps tendon ruptures after total knee arthroplasty (TKA) have historically poor outcomes. To date, there is no consensus for optimal treatment. The purpose of this study is to directly compare clinical outcomes and survivorship between allograft versus synthetic mesh for reconstruction of native extensor mechanism (EM) rupture after TKA. METHODS: A multicenter, retrospective review identifying consecutive TKA patients operated between December 2009 to November 2019 was conducted. Patients aged ≥ 45 years old with native EM disruption treated with either allograft or synthetic mesh with minimum 2 year follow-up were included. Demographic information, injury mechanism, range of motion, surgical time, revision surgeries, and postoperative Knee Injury and Osteoarthritis Outcome Scores (KOOS Jr.) were collected. Student t-tests and Fisher exact tests were used to compare the demographic data between groups. The Kaplan-Meier survival curve method was used to determine the survivorship as treatment failure was defined as postoperative EM lag >30° or revision surgery. Survival curves were compared using the log-rank test. Univariate Cox proportional hazard regression identified risk factors associated with treatment failure. RESULTS: Twenty patients underwent EM reconstruction using allograft versus 35 with synthetic mesh. Both groups had similar demographics and an average follow-up time of 3.5 years (P = 0.98). Patients treated with allograft had significantly greater postoperative flexion than patients treated with mesh (99.4 ± 9.5 allograft versus 92.6 ± 13.6 synthetic mesh, P = 0.04). Otherwise, there was no difference in postoperative outcomes between the two groups in average KOOS Jr. (P = 0.29), extensor lag (P = 0.15), graft failure (P = 0.71), revision surgery rates (P = 0.81), surgical time (P = 0.42), or ambulatory status (P = 0.34) at the most recent follow-up. Survival curve comparison also yielded no difference at up to 5-year follow-up (P = 0.48). DISCUSSION AND CONCLUSION: Our findings suggest that reconstruction with allograft or synthetic mesh leads to similar clinical outcomes with good survivorship. Future studies, including larger randomized control trials, are required to determine the superior reconstruction method for this injury. LEVEL OF EVIDENCE: III.
