Slipped Capital Femoral Epiphysis in an Adult with Panhypopituitarism: A Case Report.

CASE: Our patient was a 31-year-old woman with previously undiagnosed panhypopituitarism who presented with bilateral slipped capital femoral epiphysis (SCFE). Together with endocrinology, her treatment plan involved medical management of her panhypopituitarism and surgical correction with femoral neck osteotomy. Hormone deficiencies were corrected 6 weeks after replacement therapy began, and the patient was cleared for surgery. By 5 months after osteotomy, examination revealed delayed union and prominent screws bilaterally. Hardware exchange and repeat internal fixation were then performed. At 8 weeks after revision, she presented with avascular necrosis, and the decision was made to proceed with total hip arthroplasty. A 5-year follow-up period was documented. CONCLUSION: This case presented a rare look at SCFE in an adult patient with panhypopituitarism. Other systemic illnesses that can contribute to SCFE or other orthopaedic issues include, but are not limited to, multiple endocrine neoplasia syndromes, vitamin D deficiency, renal osteodystrophy, Kallmann syndrome, Klinefelter syndrome, and pathologies affecting the thyroid and pituitary gland.

Early Results of Supporting Free Flap Coverage of Mangled Lower Extremities with Long Saphenous Arteriovenous Loop Grafts.

BACKGROUND: The ability to salvage the mangled lower extremity is both technically challenging and time consuming. It requires the collaborative efforts among multiple surgical specialties in addition to comprehensive post-traumatic wound follow-up. Our institution has integrated a dynamic effort among these specialists in the planning and facilitating a successful limb salvage program with creation of a mangled extremity algorithm. An integral part in this process is the vascular inflow to prepare coverage for large tissue defects lacking adequate recipient targets. Utilization of long saphenous arteriovenous (AV) loop has been cited with minimal data available using larger inflow vessels in the acute trauma setting. We performed a retrospective review and describe our early experience using our protocol with AV loop creation with free flap reconstruction to salvage traumatic leg injuries. Using the data, we sought to develop a mangled extremity protocol for trauma centers to guide mangled limb salvage. METHODS: Since June 2016, 398 patients were admitted to our level II trauma facility with isolated traumatic wounds to the lower extremities. Thirty-one limbs were deemed mangled in which 21 received primary amputations due to multiple factors. Ten patients admitted from the trauma service with isolated mangled lower extremities injuries were identified for review. All 10 patients sustained severe crush injuries with large soft tissue defects and decreased perfusion for healing but deemed salvageable by multispecialty assessment. Mangled extremity severity scores were tabulated. Patients age ranged from 21-44 years, with 8 men and 2 women. Repeated debridements until successful sterilization of the wounds were accomplished. Ten long saphenous vein AV loops were anastomosed to the at or above knee popliteal vessels for free flap reconstruction. All patients were followed post-AV loop creation for vascular complications and wound assessments. RESULTS: All 10 patients had sterilization of the wounds with repair of the fracture site before vascular reconstruction. Mean debridement to surgical site sterilization was 4.3 washouts (range 2-7). Successful AV loop creation with long saphenous vein was completed in 100% of patients without vascular complications nor steal events. Free flap tissue transfers directly connected to the loop were completed using 6 rectus abdominis, 3 latissimus dorsi, and 1 anterior thigh graft within 10 days of its creation. Patency rates of the AV loop was 100% with 10 successful flap transfers and 90% amputation free survival. One flap did not survive due to recurrent bacterial infection of the hardware. The 9 patients with successful procedures reached preoperative ambulatory status within 3 months after their final surgery. At 24 months follow-up, 90% amputation free survival is still maintained. CONCLUSIONS: Although a small patient cohort, utilization of long saphenous vein AV loop is successful as a bridge to free flap transfer for isolated mangled lower extremities. Development and incorporation of our mangled extremity protocol to guide limb salvage has proven successful in our early experience. Long-term data need to be complied to assess patency of the free flap transfer and quality of life outcomes.

Multimodal Pain Management of Femoral Neck Fractures Treated With Hemiarthroplasty.

The purpose of this study was to evaluate a multimodal pain management program incorporating periarticular injections of liposomal bupivacaine after hemiarthroplasty treatment of femoral neck fractures. This retrospective study selected patients treated with periarticular injections of liposomal bupivacaine within the multimodal pain management program (LBUP) (n = 100) and a control group of patients treated without local infiltration (n = 78). Similar pain control was achieved between both groups from day 1 to day 4 postsurgery (min p = .392). Length of stay was significantly lower for LBUP patients (4.8 days vs. 5.7 days, p = .013), and LBUP patients were significantly more likely to be ambulatory at discharge (82% vs. 69%, p = .013). LBUP patients were also less likely to need the intensive care unit (4% vs. 14%, p = .027). The percentage of patients with at least one opioid-related adverse event was lower in the LBUP group (3% vs. 8%, p = .156) as was the 90-day mortality rate (2% vs. 8%, p = .069), but the differences were not statistically significant.

Current Practices for Multimodal Pain Management Using Liposomal Bupivacaine in Extracapsular and Intracapsular Hip Fracture Surgery: Expert Panel Opinion.

BACKGROUND: Liposomal bupivacaine (LB) has demonstrated efficacy across a range of surgical settings, including shoulder, knee, and hip surgery. However, data are limited on the use of LB as part of a multimodal pain management approach in hip fracture surgery. METHODS: On April 1, 2017, 4 orthopaedic surgeons and 3 anesthesiologists convened to discuss current practices and develop a consensus statement related to local infiltration analgesia with LB for hip fracture surgical procedures within the context of a multimodal opioid-sparing pain management approach. Separate workshops addressed intracapsular and extracapsular hip fracture surgery. RESULTS: Multimodal strategies before, during, and after hip fracture surgery are paramount to optimizing pain control and minimizing opioid requirements. LB infiltration should occur intraoperatively near the time of closing the incision. For both intracapsular and extracapsular procedures, oral or intravenous acetaminophen, a nonsteroidal anti-inflammatory drug (NSAID) of choice, and tramadol should be given preoperatively. Presurgical fascia iliaca block with bupivacaine HCl may help bridge the period before LB takes effect. After both procedures, patients should receive 1 dose of intravenous acetaminophen, an NSAID, and opioid rescue medication as needed, starting with tramadol. Postoperative NSAIDs may help minimize opioid use. Patient and provider education are integral to managing patient expectations and alleviating concerns about pain and opioid use. Standardized, validated, and appropriately timed pain assessments are also necessary to optimize postsurgical pain management. CONCLUSIONS: These consensus recommendations regarding multimodal pain management protocols incorporating local infiltration analgesia with LB for extracapsular and intracapsular hip fracture procedures serve as a basis for additional research. LEVEL OF EVIDENCE: Level V.

Infiltration Techniques for Local Infiltration Analgesia With Liposomal Bupivacaine in Extracapsular and Intracapsular Hip Fracture Surgery: Expert Panel Opinion.

BACKGROUND: Liposomal bupivacaine (LB) has demonstrated efficacy in improving pain scores and reducing opioid consumption across a variety of surgical settings, including orthopaedic surgery. However, meticulous infiltration techniques combined with a multimodal approach are important to optimizing outcomes. METHODS: A panel of 4 orthopaedic surgeons and 3 anesthesiologists convened on April 1, 2017, to discuss current practices and develop a consensus statement regarding local infiltration analgesia with LB for extracapsular and intracapsular hip fracture surgery, including LB infiltration techniques. RESULTS: Optimizing surgical outcomes with LB in hip fracture surgery requires an understanding of the neuroanatomy of the surgical site and the pharmacology of the drug. Meticulous infiltration technique is critical to achieve optimal results with LB given its viscosity and reduced diffusion compared with bupivacaine HCl. For extracapsular procedures, a total injection volume of 120 mL is recommended, whereas intracapsular procedures typically require a lower volume (∼80 mL). In both cases, infiltration is best achieved using a 22-gauge needle and applying a tracking and/or fanning technique. To ensure optimal placement, LB should be infiltrated using multiple, small-volume (1- to 5-mL) injections spaced at 1.0-cm intervals. CONCLUSIONS: These consensus recommendations regarding LB infiltration techniques can serve as a resource for designing clinical studies to evaluate outcomes using periarticular infiltration of LB in extracapsular and intracapsular hip fracture surgery as part of a multimodal pain management approach.

Local infiltration of liposome bupivacaine in orthopedic trauma patients: case-based reviews.

Orthopedic trauma surgery is often associated with considerable postoperative pain, which can result in a cascade of direct and indirect clinical consequences. Patients undergoing orthopedic trauma surgery are at risk for the development of chronic postsurgical pain, which may persist for 2 years or longer. Effective approaches to reducing postoperative pain in orthopedic trauma surgery patients include the use of minimally invasive procedures and multimodal analgesia. Infiltration of the surgical site with EXPAREL® (bupivacaine liposome injectable suspension), an extended-release local anesthetic, represents an advance in the multimodal management of postoperative pain. As part of a multimodal regimen, EXPAREL® has been shown to provide effective, safe, and efficient analgesia across a range of surgical procedures. Two cases that illustrate the use of EXPAREL® in orthopedic trauma are described. The first case involves repair of a subtrochanteric nonunion in a 63-year-old woman with a history of bisphosphonate use and prior treatment with a cephalomedullary nail. The second case involves a young woman undergoing outpatient surgery for repair of a fractured clavicle. Both patients experienced good control of postsurgical pain, supporting the clinical utility of EXPAREL® in orthopedic trauma surgery.

Distal biceps tendon insertion: an anatomic study.

Knowledge of the exact location of the distal biceps brachii insertion is crucial when performing tendon reconstruction or repair. To quantitatively describe the morphology of the distal biceps brachii insertion, 20 cadaveric arms were examined. Linear and angular measurements, including the footprint dimensions and shape, radial tuberosity dimensions and irregularities, and the rotational position of the tuberosity and footprint, were obtained. The axial and transverse dimensions of the radial tuberosity and distal biceps tendon footprint measured 24.2 x 12 mm and 18.7 x 3.7 mm, respectively. The insertion footprint is on the posterior/ulnar aspect of the radial tuberosity centered at approximately 30 degrees anterior to the lateral/coronal plane with the forearm fully supinated. This explains why any preoperative limitation in supination may make an anatomic repair difficult through a single anterior incision. To our knowledge, this is the first study to quantitatively describe the angular location of the radial tuberosity and the relationship of the distal biceps tendon on the tuberosity.
