Fracture-dislocation of the neck of the talus in a ten-year-old child: a case report and review of the literature.

A ten-year-old female underwent open reduction and internal fixation of a Hawkins type III fracture of the talar neck. The fracture united within three months. However, avascular necrosis of the body of the talus occurred. Partial collapse of the talar body ensued despite protection from weight-bearing for eight months after surgery. This case illustrates that fracture-dislocation of the talus can occur in a child and has a guarded prognosis.

Comparison of measurements obtained by use of an electrogoniometer and a universal plastic goniometer for the assessment of joint motion in dogs.

OBJECTIVE: To compare measurements obtained by use of a universal plastic goniometer (UG) and an electrogoniometer (EG) and from radiographs and to compare joint motion in German Shepherd Dogs and Labrador Retrievers. ANIMALS: 12 healthy adult German Shepherd Dogs and data previously collected from 16 healthy adult Labrador Retrievers. PROCEDURES: German Shepherd Dogs were sedated. One investigator then measured motion of the carpal, cubital (elbow), shoulder, tarsal, stifle, and hip joints of the sedated dogs. Measurements were made in triplicate with a UG and an EG. Radiographs were taken of all joints in maximal flexion and extension. Values were compared between the UG and EG and with values previously determined for joints of 16 Labrador Retrievers. RESULTS: An EG had higher variability than a UG for all dogs. The EG variability appeared to result from the technique for the EG. German Shepherd Dogs had lower values in flexion and extension than did Labrador Retrievers for all joints, except the carpal joints. German Shepherd Dogs had less motion in the tarsal joints, compared with motion for the Labrador Retrievers, but had similar motion in all other joints. CONCLUSIONS AND CLINICAL RELEVANCE: A UG is reliable for obtaining measurements in German Shepherd Dogs. There was higher variability for the EG than for the UG, and an EG cannot be recommended for use.

[Injuries of the tibialis posterior tendon: diagnosis and therapy].

Complete traumatic rupture of the tibialis posterior tendon is absolutely rare. From the scarce case reports in the medical literature a extreme pronation-abduction or pronation-external rotation mechanism according to the Lauge-Hansen classification can be presumed, leading to a malleolar fracture because of forced pronation, external rotation and dorsiflexion of the foot. With primary suture the prognosis is favorable. Traumatic dislocations, mostly with luxatio pedis sub talo, are treated by atraumatic reduction and refixation of the retinaculum. Again, the prognosis is favorable. Incomplete traumatic rupture of the tibialis posterior tendon with development of posttraumatic pes plano valgus, according to case reports and our own experience result from severe pronation-external rotation-soft tissue injuries as well as with pronation-abduction or pronation-external rotation-type ankle fractures. In these cases no macroscopic rupture of the tendon is evident, however occult interstitial micro-ruptures can occur because of excessive stretching, which can be determined histologically. If conservative measures fail, a modified Evans osteotomy to lengthen the lateral foot column is indicated. Degenerative complete and incomplete ruptures of the tibialis posterior tendon are predominantly seen in women more than 42 years old. Staging of this entity can be achieved with clinical tests (muscular force, external rotation), ultrasound, weight-bearing x-rays, CT and MRT. According to the degree of decompensation of tendon function, treatment consists of augmentation, modified Evans procedure or triple arthrodesis of the hind-foot.

Isolated dorsal dislocation of the intermediate cunieform: a case report and review of the literature.

We present one very rare case of patient with an isolated dorsal dislocation of the middle cuneiform (closed injury) sustained after a fall. He was treated surgically through a dorsal approach and fixation with K-wires after manual reduction was unsuccessful. A cast was applied for a total of 6 weeks followed by active range-of-motion exercises. At the 18-month follow-up, he was asymptomatic.

A single surgeon's experience of treatment of Lisfranc joint injuries.

This paper assesses the outcomes and complications of Lisfranc joint injuries treated at a regional trauma centre under the care of a single surgeon. We performed a retrospective study of all patients that underwent ORIF of a Lisfranc joint injury over a 5-year period. Case note review, radiology review, and questionnaire assessment were performed. We analysed for correlations between outcome and injury type, mechanism of injury, and presence of other ipsilateral limb injury and pure ligamentous injury. All injuries were classified according to a system described by Myerson et al. (Types A, B1, B2, C1, C2). Radiographs were also assessed for the presence of pure ligamentous injury. Outcome was measured using the American Orthopaedic Foot and Ankle society (AOFAS) midfoot score. Twenty-five injuries (24 patients) were identified and 16 injuries (15 patients) were available for follow. The mean duration of follow up was 42.6 months (11-69). The mean outcome score was 78.3 (38-100). The outcome scores for pure ligamentous injury (74.9) and for mixed bony and ligamentous injury (80.9) had no significant difference (p=0.61). High-energy trauma accounted for 50% of cases, and scored significantly less than low energy trauma (69.1 versus 87.4, p<0.05). There was an associated injury in the ipsilateral limb in 31% of cases and this group had a poorer outcome (63.0 versus 85.3, p<0.035). The most common injury type was B2 (38%). Type C2 injuries (divergent with total displacement) had a worse outcome than the mean outcome of all other categories (60.5 versus 84.4, p<0.01). Our mean outcome from ORIF of Lisfranc joint injuries is comparable to internationally quoted figures. Pure ligamentous injuries did no worse statistically than mixed bony and ligamentous injuries. Poorer outcome was associated with high-energy trauma, associated injury on the ipsilateral limb, and Type C2 injuries.

Mechanical behavior of the Lisfranc and dorsal cuneometatarsal ligaments: in vitro biomechanical study.

OBJECTIVES: To define the anatomy and mechanical properties of two ligaments stabilizing the medial tarsometatarsal joints: the Lisfranc ligament and the dorsal cuneometatarsal ligament. DESIGN: Cadaveric study in normal feet. SETTING: Biomechanics laboratory. PATIENTS OR PARTICIPANTS: Twelve fresh-frozen cadaveric feet were studied. INTERVENTION: The Lisfranc and dorsal cuneometatarsal ligaments were dissected, dimensions measured, and material properties determined with a servohydraulic MTS machine on bone-ligament-bone preparations. MAIN OUTCOME MEASUREMENTS: Stiffness, strain, stress, modulus, failure load, ligament length, width, thickness, and cross-sectional area were determined. RESULTS: Dorsal ligament stiffness was 66.3+/-18.3 newtons per millimeter and the Lisfranc ligament stiffness was 189.7+/-57.2 newtons per millimeter. The failure load of the dorsal ligament averaged 150.7+/-33.1 newtons and for the Lisfranc ligament, 368.8+/-126.8 newtons. CONCLUSIONS: The stiffness and load to failure of the dorsal cuneometatarsal ligament were much higher than anticipated, which indicates that it contributes significantly to stabilizing the second metatarsal to the first cuneiform.

Deltoid ligament strain after correction of acquired flatfoot deformity by triple arthrodesis.

Deltoid insufficiency represents a difficult surgical challenge. We have witnessed patients who have developed a valgus tibiotalar deformity following a properly positioned triple arthrodesis. To investigate whether the triple arthrodesis itself, by creating a rigid triple joint complex below the ankle, leads to increased strain of the deltoid complex, a flatfoot model was created in 8 fresh-frozen below-knee amputation specimens. Each specimen was loaded in three gait cycle (GC) positions: Heel strike (0% GC), midstance (10% GC), and heel rise (40% GC). The three components of the ground reaction force (GRF) and the tendon forces consistent with those respective positions were applied. To simulate a posterior tibial tendon insufficient state the posterior tibial tendon was not loaded. Strain at the tibiocalcaneal fibers of the superficial deltoid ligament complex was determined at each of the three foot positions. A triple arthrodesis was performed and the deltoid strains were again recorded for each position. A significant increase in the strain of the deltoid ligament was observed for only the heel rise position (p=0.007) in our cadaver model following triple arthrodesis. The results favor medializing the calcaneus following arthrodesis to protect the deltoid complex.

Calcaneocuboid joint instability: a novel operative technique for anatomic reconstruction.

A case history of a 13-year-old female national top-level gymnast, suffering from calcaneocuboid joint instability, is presented. The procedure was done as an anatomic repair by capsular reefing, which was augmented using a local periosteal flap. Initially, the athlete twisted her ankle. Clinical investigation revealed no sign of a lateral ankle ligament injury, but following this initial examination, recurrent giving-way of the foot occurred. She additionally felt significant but diffuse pain on the lateral side of the foot during loading in training and competition. For 2 months she was unable to run and conservative treatment failed. Diagnosis of a calcaneocuboid instability was established 4 months after the initial lesion by clinical and x-ray stress examination of the calcaneocuboid joint. Open surgery was successfully performed. Early functional posttreatment was done and the patient returned to full high-level gymnastics ability 16 weeks after surgery. Two years later, a similar injury occurred to the opposite calcaneocuboid joint and the same operative procedure again led to full sports ability.

The treatment of tarsometatarsal injuries.

In order to analyze the value of operative treatment for tarsometatarsal injuries, 31 consecutive fracture-dislocation injuries from 1975 to 1988, and 11 cases of undislocated injuries were reviewed. Forty patients (41 injuries) could be contacted. The average follow up was 5 years. Twenty-two of the dislocated injuries were treated with open reduction and fixation, usually K-wires. All injuries were classified radiologically. By means of a questionnaire, it was found that 7 had excellent results, 13 good, and 21 poor. No case where anatomical reduction was not achieved could be classified as excellent, and half (5 of 10) received full disability pension. When anatomical reduction was achieved, half had good or excellent results and only 5 of 20 received a disability pension. Initially undislocated injuries had a better prognosis, with 8 of 11 having excellent or good results, and none receiving pension. These injuries should be treated aggressively with open reduction and fixation when there is any displacement. Despite this treatment, one-half of patients with dislocated injuries as well as one-fourth of those with initially undislocated injuries will still suffer from pain and permanent disability probably due to soft tissue damage and instability.

Pigmented villonodular synovitis of the foot and ankle: a review of six cases.

Pigmented villonodular synovitis is a rare but well recognized proliferative lesion of synovial tissue. It has been most commonly described in the knee and hip, with most series reporting <5% occurrence in the foot and ankle. Six patients with pigmented villonodular synovitis of the foot and ankle that was treated between 1978 and 1997 were reviewed. Four of the patients had not been previously diagnosed, and two patients presented with recurrent disease. All six were women. Two patients' disease presented isolated to the ankle joint. The other four involved more than one joint: subtalar joint and midfoot in two, and the metatarsal region in two. The histology of the primary and recurrent lesions did not differ. The recurrent lesions were more diffuse and locally destructive. Five were found on magnetic resonance imaging to be a low-to-medium signal intensity mass on T1- and T2-weighted images. Surgical management ranged from simple excision to synovectomy to Lisfranc amputation. Average follow-up was 13 months (range, 3 weeks to 51 months). One of the lesions recurred 4 years later.

Outcome after open reduction and internal fixation of Lisfranc joint injuries.

BACKGROUND: Open reduction and internal fixation has been recommended as the treatment for most unstable injuries of the Lisfranc (tarsometatarsal) joint. It has been thought that purely ligamentous injuries have a poor outcome despite such surgical management. METHODS: We performed a retrospective study of patients who underwent open reduction and screw fixation of a Lisfranc injury in a seven-year period. Among ninety-two adults treated for that injury, forty-eight patients with forty-eight injuries were followed for an average of fifty-two months (range, thirteen to 114 months). Fifteen injuries were purely ligamentous, and thirty-three were combined ligamentous and osseous. Patient outcome was assessed with use of the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and the long-form Musculoskeletal Function Assessment (MFA) score. RESULTS: The average AOFAS midfoot score was 77 points (on a scale of 0 to 100 points, with 100 points indicating an excellent outcome), with patients losing points for mild pain, decreased recreational function, and orthotic requirements. The average MFA score was 19 points (on a scale of 0 to 100 points, with 0 points indicating an excellent outcome), with patients losing points because of problems with "leisure activities" and difficulties with "life changes and feelings due to the injury." Twelve patients (25 percent) had posttraumatic osteoarthritis of the tarsometatarsal joints, and six of them required arthrodesis. The major determinant of a good result was anatomical reduction (p = 0.05). The subgroup of patients with purely ligamentous injury showed a trend toward poorer outcomes despite anatomical reduction and screw fixation. CONCLUSIONS: Our results support the concept that stable anatomical reduction of fracture-dislocations of the Lisfranc joint leads to the best long-term outcomes as patients so treated have less arthritis as well as better AOFAS midfoot scores.
