[Full Text]. Patients filled in . Indian J Orthop. The purpose of this study was to assist surgeons treating calcaneal fractures in choosing the most predictive fracture classification and clinical outcome tool. - Essex Lopresti: [QxMD MEDLINE Link]. Intra-articular fractures of the calcaneus. Classification (Carter-Rowe) Type I Type Ia - Fracture of the calcaneal tuberosities. J Orthop Trauma. Degan TJ, Morrey BF, Braun DP. - Complications of Treatment, Current Concepts Review. 2018 May-Jun. [QxMD MEDLINE Link]. Epub 2020 Oct 27. LINDSAY WR, DEWAR FP. Calcaneus injuries represent 2% of all fractures seen in adults. Rowe Classification: Types I-III do not involve the subtalar joint. Open calcaneal fractures: results of operative treatment. [QxMD MEDLINE Link]. 3) Vertical Park CH, Yoon DH. 52 (3):239-243. J Bone Joint Surg. Calcaneus fractures. At follow-up, only 12 of the 22 patients (55%) of the patients had very good or good clinical results; four had average results, and six had poor results. Conservative versus operative treatment. The calcaneus is the most commonly fractured tarsal bone and accounts for about 2% of all fractures. Norris correctly described a compression mechanism in calcaneus fractures in 1839, and in 1843, Malgaigne describedtwo types of calcaneal fractures; this description formed the first rudimentary classification system. [QxMD MEDLINE Link]. document.write (" 2 mm displacement, posterior facet displacement >2 to 3 mm, flattening of Bohler angle, or varus malalignment of the tuberosity, anterior process fracture with >25% involvement of calcaneocuboid joint, wait 10-14 days until swelling and blisters resolve and wrinkle sign present 10-14 days, no benefit to early surgery due to significant soft tissue swelling, displaced tuberosity fractures with posterior skin compromise should be addressed urgently, number of intra-articular fragments and the, surgical treatment decreases the risk of post-traumatic arthritis, age > 50 (similar outcomes with surgical and nonsurgical treatment), initial Bhler's angle <0 (these injuries do poorly regardless of treatment), lower Bhler angles suggest greater energy absorbed, open fractures (significant soft tissue injury and engery absorbed), bilateral calcaneal fractures (significant gait problems following bilateral injuries), factors associated with most likely need for a secondary subtalar fusion, male worker's compensation patient who participates in heavy labor work with an initial Bhler angle less than 0 degrees, standard short-leg cast for calcaneal stress fractures, standard short-leg cast applied with mild equinus, windowed over posterior heel to allow for frequent skin checks, requires close follow-up to determine if pull of gastrocnemius-soleus dispaces fracture, weekly cast changes are necessary due to high incidence of skin complications, high incidence of vascular insufficiency and diabetes in this population, ideal for poor soft tissue coverage or patients with peripheral vascular disease, Steinmann pin placed into the fracture site anteromedially-to-posterolateral to leverage fragments into place, additional K-wires and Steinmann pins are placed from posterior-to-anterior and lateral-to-medial to secure remaining bone fragments, calcaneal transfixin pin can be used to distract fracture, percutaneus tamps and elevators can be used to raise the articular surface, pins are cut flush with the skin and removed 8-10 weeks post-op, can be combined with distracting external fixator, pins placed in calcaneal tuberosity, cuboid, and distal tibia, restor calcaneal height, width, and alignment, can be combined with percutaneous cannulated screws, extensile lateral L-shaped incision is most popular, vertical portion inbetween posterio fibula and achilles tendon, horizontal portion in line with 5th metatarsal base, a more inferior incision protects the sural nerve, provides access to the calcaneocuboid and subtalar joints, full-thickness skin, soft tissue, and periosteal flaps are developed, lateral calcaneal branch of peroneal artery, superior flap contains the calcaneofibular ligaments and peroneal tendon sheath, sural nerve and peroneal tendons are retracted superiorly, fracture opened and medial wall reduced going medial to lateral, reduction confirmed indirectly via fluoroscopy, tuberosity reduction is done under direct visualization, manual traction, Schanz pins, and minidistractors, height and length of tuberosity is recreated, definitive fixation with plates and screws, restore Bhler's angle and calcaneal height, minimally invasive incision that minimizes soft tissue dissesction, reduces wound complications associated with extensile lateral incision, allows direct visualization of the posterior facet, anterolateral fragment, and lateral wall, same incision can be utilized for secondary subtalar arthrodesis or peroneal tendon debridement, patient placed in lateral decubitus position, incision made in line with the tip of the fibula and the base of the 4th metatarsal, extensor digitorum brevis retracted cephalad to expose sinus tarsi and posterior facet, Schanz pin inserted percutaneously in posteroinferior tuberosity going from lateral to medial, provides distraction and aids with reduction, fibrous debris and fat removed from sinus tarsi, small elevator or lamina spreader placed under posterior facet fragment to aid in reduction, K-wires inserted for provisional fixation aimed towards the sustentaculum, two screw are placed lateral-to-medial to engage sustentaculum and support facet, one large fully threaded screw from posterior-to-anterior to support axial length of calcaneus, low-profile plate is applied underneath a well developed soft tissue envelope with screws engaging anterolateral and tuberosity fragments, nonweight bearing for 6-8 weeks post-op with ankle range-of-motion exercises beginning 2 weeks post-op, manipulate the heel to increase the calcaneal varus deformity, manipulate the heel to correct the varus deformity with a valgus reduction, stabilize the reduction with percutaneous K-wires or open fixation as described above, arthroscopic-assisted reduction and internal fixation, improved visualization of articular surface and carilage lesions, increased swelling from fluid extravasation, can be combined with sinus tarsi approach, patient positioned in lateral decubitus position, fluoroscopy unit positioned posterior and oblique to patient, anterolateral and posterolateral portals are used to visualize posterior facet, loose bodies and cartilage fragments are removed with a shaver, Freer elevator is introduced into one of the portal sites and used to elevate the posterior facet, Schanz pin to control tuberosity fragment, cannulated screws from the posterior aspect of the calcaneal tuberosity to the anterior aspect of the calcaneus, lateral-to-medial screws placed in sustentaculum, buttress screw from the posterior aspect of the calcaneal tuberosity to the subchondral bone of the posterior facet, posterior approach for calcaneal tuberosity fractures, fracture fragment is mobilized and debrided, plantar flexion of foot aids with reduction, presence of gastrocnemius tightness may preclude reduction, Strayer procedure may be performed to aid in reduction, figure-of-8 tension-band wire passed around ends of K-wires or cannulated screws, Krackow sutures passing through bone tunnels, restricted weight bearing for 6 weeks followed by progression of weight bearing an additional 6 weeks, performed in highly comminuted Sanders IV intraarticular fractures, high rate of secondary fusion after ORIF with these injuries, avoids added treatment costs and decreases time off from work, can be performed through an extensile lateral or sinus tarsi approach, fracture reduction is perfromed in a similar fashion as ORIF, articular cartilage of the subtalar joint denuded to bleeding subchondral bone, cannulated compression screws are placed from the posterio calcaneal tuberosity to the talar dome, lateral fixation plate applied to hold reduction, increased risk in smokers, diabetics, and open injuries, may consider nonoperative treatment in these patients, tongue type fractures at high risk (>20%) for posterior skin necrosis, should be splinted in 30 degrees of planarflexion to relieve soft tissue tension, keep all hardware away from the corner of the incision, delayed wound healing is the most common complication, can be addressed with ankle bracing (gauntlet type), NSAIDs, injections, and physical therapy, may require bone block subtalar arthrodesis to address loss of calcaneal height, important when there are symptoms of anterior ankle impingement, Lateral impingement with peroneal irritation, at risk with placement of lateral to medial screws, especially at level of sustentaculum tali (constant fragment), loss of height, widening, and lateral impingement, distraction bone block subtalar arthrodesis, incongruous subtalar joint/post-traumatic DJD, results from posterior talar collapse into the posterior calcaneus, Lateral exostosis with no subtalar arthritis, Lateral exostosis with subtalar arthritis, Lateral exostosis, subtalar arthritis, and varus malunion, increased due to mechanism (fall from height), smoking, and early surgery, lateral soft tissue trauma increases the rate of complication, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries.
