The treatment of requires attention to detail and adherence to well-researched treatment principles to avoid complications which necessitate additional surgeries and can compromise patient outcomes. In this example, a patient in their 50’s was on vacation in the Caribbean when they were involved in a motor vehicle accident, sustaining a fracture that was treated with standard antegrade femoral nailing.

The patient was told to remain nonweightbearing and presented to our office at 6 weeks postop. Unfortunately, there was a missed femoral neck fracture that was not stabilized with the original implant. Surprisingly, the patient was able to mobilize reasonably well with a walker and refused further surgery at this time. The patient was lost to follow-up but re-presented a year later with a chief complaint of limping and leg length discrepancy. At this point the femoral shaft had healed / remodeled and the femoral neck had collapsed / healed in further varus.

While osteotomy and re-fixation was certainly an option, the patient opted for conversion to to restore limb mechanics and to allow for immediate weight bearing. Six months after surgery, the patient has resumed all prior activities. Given the widening of the healed femur diameter with robust callus, the decision was made to not perform prophylactic plating of the femur. The primary learning point of this case is to always “protect ya neck” when performing antegrade femoral nailing and to always have a high index of suspicion for occult ipsilateral femoral neck fracture when treating femoral shaft fractures 👍

With ever-increasing volumes of being performed, we unfortunately are also seeing a rise in cases, which pose unique treatment challenges. In this case example, an elderly patient who previously underwent hip replacement with a cemented stem sustained a fall, resulting in a fracture below the stem. Careful scrutiny of the stem shows that the cement mantle has fractured and subsided, with radiolucent lines suggestive of loosening of the stem - all of which preclude the possibility of retaining the original stem.

Reconstruction of this injury started with direct reduction of the fracture distal to the stem followed by cerclage cabling and plating of the entire femur to mitigate against future fractures. The initial proximal fixation was done with the original implant in place and screws aimed around the stem. Once the femur was stable enough for manipulation, the hip was dislocated and the original stem extracted along with meticulous removal all original cement. The original liner was replaced with a larger dual mobility liner to mitigate against late instability.

Given the patient’s low demand and poor bone quality, the decision was made to revise the stem with a slightly shorter cemented Exeter stem with dual mobility bearing. Finally, addition fixation was added through the plate to complete the construct. Patient was allowed immediate full weight bearing with stable construct and good clinical function three months out. How would others have handled this injury? Would an original press-fit stem (+/- collar) have altered the injury characteristics? Always a great discussion 👍

For , we present a case of an elderly patient who sustained a posteromedial tibial plateau after a slip and fall while vacationing out of state. The fracture was fixed at a local hospital and the patient came to the office already six weeks after surgery. Assessment of the imaging studies show a malreduced fracture with residual posterior displacement and subluxation of the tibial plateau which leads to posteromedial femoral subluxation and settling of the lateral femoral condyle into the lateral tibial defect. The CT scan images show the residual fracture gaps, displacement, and edge-loading of the cartilage ➡️ guaranteed post-traumatic arthritis.

Given the patient’s age and activity level, the decision was made to ultimately perform instead of trying to re-fix the fracture. Unfortunately, because of , the patient’s narrow-network / high deductible HMO plan, and difficulty obtaining authorization, the patient could not be scheduled for several months. The patient’s P*P ordered PT and the patient noted increased pain after an aggressive manipulation session over a month prior to surgery. On the date of surgery, the patient was noted to have newly discovered subacute transcondylar femur fracture with significant flexion of the femoral condyles 🤦‍♂️

Needless to say, this changed the surgical plan significantly… After performing a standard knee replacement incision which allowed access to the proximal screws in the plate, the distal screws in the tibial shaft were removed percutaneously. Given the femur fracture, a distal femoral replacement component was used and a long cemented tibial stem was used to bypass the prior screw holes. The resected specimen shows the wear of the tibial plateau as well as the healed femur fracture with flexion deformity. Fortunately, the patient was able to bear full weight the same day of surgery, the first time standing / walking on her injured leg in over 4 months. Also fortunate to work at as a where we can provide care to all especially in situations where patients have been turned away from other institutions 🙌

For , we present a case of an elderly patient who fell at home and was seen in the ER with what were read as negative x-rays. The patient was experiencing worsening pain and was ultimately noted to have a subacute / impacted femoral neck fracture. Given the chronicity of the fracture and symptoms, the decision was made to proceed with which we now exclusively perform through a incision for improved cosmesis and wound healing.

The patient was doing well post-op but unfortunately fell several weeks later and presented with a with loosening and subsidence of the femoral stem. Revision surgery was performed by going back through the original bikini incision, removing the loose stem, and cabling the femur below the level of the lesser trochanter. A monobloc diaphyseal-engaging stem was used where trialing could be performed off the reamer. Excellent exposure without additional releases was achieved through the original bikini incision for cabling and straight stem preparation / insertion. The final stem had excellent fill of the femoral canal and the patient was allowed full weight bearing immediately. We have found that the soft-tissue friendliness of the bikini incision allows even for revision work without much difficulty. While not extensile in the traditional sense, we have found it to be much more soft-tissue friendly to create a second accessory lateral incision for any work needed in the shaft rather than extending a vertical incision into a lateral thigh incision. Always curious to hear how other colleagues would tackle this problem 👍

In recognition of a , we present a recent uncommonly seen case that presented to Memorial Healthcare System . This patient was involved in a high-speed car accident over 30 years ago with severe bilateral pelvic fractures and right acetabulum (hip socket fracture). At the time, the patient was deemed too young for , and as such, in addition to fixation of the pelvic ring and acetabular fractures, a procedure was performed as a salvage operation by the phenomenal Orthopaedic Trauma Service at Hospital for Special Surgery back in the 1990’s.

The patient did well for many years but recently developed worsening pain in the hip, lower back, and opposite hip and knee in part because of the leg shortening necessary to obtain an adequate compression of the hip joint for fusion. A lengthy discussion was had about the potential complexities and risks associated with taking down a hip fusion and converting to hip replacement. A pre-operative CT scan revealed large cystic areas and osteopenia in the pelvis with anticipated difficulties to achieve solid implant placement.

The decision was made to perform an procedure using the inferior limb of the patient’s prior iliofemoral incision. After removing the trochanteric osteotomy screws percutaneously, the femoral neck / head screws were removed prior to neck osteotomy. The socket was recreated with reamers and a metal-cutting burr was necessary to remove several obstructing screws, but it became evident with the cavitary pelvic defects, traditional component placement would not be feasible. As such, a cemented cup construct was utilized and excellent cement interdigitation and fill was achieved into the cystic areas and around remaining screws. The stem was a standard primary stem and leg lengths were able to be equalized.

Immediately after surgery, the patient noted improved sitting posture, walking balance, improved leg length symmetry, and was able to return to work by six weeks. Always curious how other colleagues would have approached this challenging problem - posterior approach? Cage or cup-cage construct? Feedback and insights welcome!

“Life is like a box of chocolates…” When it comes to evaluating a patient for a revision of a prior surgery, it’s absolutely true that “you never know what you’re going to get”, as Forrest Gump famously says. In this example, a patient in their late 40’s came to the office with increasing pain / instability in her knee that was done over 10 years ago (knee replacement in one’s 30’s already raises questions and 🚩). The patient also has a history of connective tissue disorder with generalized joint laxity. On exam, there was gross collateral and flexion instability. X-rays show appropriate implant placement without obvious loosening but with asymmetric joint space suggestive of ligament imbalance.

At the time of revision surgery, intraoperative stress views confirmed the laxity of the collateral ligaments. Upon opening the knee, it was evident that the PS post had broken off the liner and along with the inherent laxity of the knee, the additional motion led to significant wear and destruction of the posteromedial portion of the liner. In addition, there was significant osteolysis behind the distal femoral condyles while the posterior condyles, metaphysis, and proximal tibia were spared with good bone quality given the patient’s young age.

Reconstruction was performed using a rotating platform revision tibia with pressfit stem as well as a standard revision femur with distal augments and cemented stem along with rotating platform constrained liner to provide joint stability. Rationale being that if the patient experiences further laxity in the years to come, revision to a hinge would allow retention of the tibial component and relatively straightforward femoral revision without worrying about cones / sleeves that weren’t felt to be necessary given the patient’s young age and good bone stock. Fortunately, the patient was discharged home the day following surgery and noticed dramatic improvement in her function and stability immediately after surgery. Always interested to hear how colleagues might have treated this problem differently!
