Effect of Body Mass Index on Pedobarographic and Patient-Reported Outcome Measures in Adolescent Flexible Flat Feet

BACKGROUND

Although adolescent flexible flatfoot deformity (FFD) is common, little is known regarding the effect of weight on associated symptomatology. This study uses pedobarography and patient-reported outcome measures (PROs) to determine if overweight adolescents with FFD have more severe alterations in dynamic plantar pressures than normal body mass index percentiles (wnBMI) with FFD and if such alterations correlate with pain and activity.

METHODS

A retrospective review of patients aged 10 to 18 years with nonsyndromic symptomatic FFD was performed. Overweight (BMI percentile ≥ 85%) patients were compared with wnBMI patients with regard to dynamic plantar pressure measures and PRO scores. Pedobarographic data were subdivided into regions: medial/lateral hindfoot and midfoot, and first, second, and third to fifth metatarsals. Plantar pressure variables were normalized to account for differences in foot size, body weight, and walking speed. Contact area (CA%), maximum force by body weight (MF%), and contact time as a percentage of the rollover process (CT%) were calculated. Two foot-specific PROs were assessed, including the Foot and Ankle Outcome Score and the Oxford Ankle Foot Measure for Children.

RESULTS

Of the 48 adolescents studied, 27 (56%) were overweight and 21 (44%) were wnBMI. After normalization of the data, overweight patients had significantly greater medial midfoot MF%, whereas CT% was increased across the medial and lateral midfoot and hindfoot regions. Correlations showed positive trends: as BMI percentile increases, so will CA and MF in the medial midfoot, as well as CT in the medial and lateral midfoot and hindfoot. Significant differences were seen between groups, with the overweight group reporting lower sports and recreation subscores than the wnBMI group. No significant differences were seen in the pain and disability subscores.

CONCLUSIONS

Although overweight adolescents with FFD exhibit greater forces and more time spent during the rollover process in the medial midfoot than normal-weight patients, they did not report worse pain or disability associated with their flat foot deformity.

Transverse pinning of concomitant first and second metatarsal fractures using 1.5mm K-wires; case report and technical note

Introduction and importance

Here we represented a new technique of closed reduction and transverse pinning to address first metatarsal comminuted fractures in patients with a concomitant second metatarsal shaft fracture.

Case presentation

The first metatarsal comminuted fracture coincides with the second metatarsal simple fracture in this forefoot injury case. In a new technique, we used close reduction and percutaneous pinning (CRPP) in a transverse direction of pins to achieve a satisfactory outcome.

After performing traditional CRPP to fix the second metatarsal fracture, it served as physical support for the first metatarsal fixation. We drilled two 1.5mm pins through the first metatarsal bone at each proximal and distal side of the fracture site, transversely passed to the second metatarsal bone. Transverse pins came along from the first metatarsal medial side to the lateral. After six-week and 12-month follow-up, the patients had minimal pain with complete radiological and clinical fracture healing and no complication.

Clinical discussion

Here, internal fixation was unsuitable due to extensive soft-tissue injury and inadequate bone support. Despite the many advantages of external fixators, they have drawbacks that persuade us to perform our new technique: using K-wires for transverse pinning fixation of the first metatarsal fracture using an adjacent metatarsal as support. This minimally invasive approach is profitable because of its minimal soft tissue damage, affordable price, and convenient access.

Conclusion

The transfixation technique with K-wires is rarely used to treat metatarsal fractures. It may be helpful in similar cases of comminuted first metatarsal fracture with satisfactory outcomes.

•

We introduced an applicable method for fixing comminuted first metatarsal fracture.

•

Transverse pinning has appropriate clinical and radiological healing.

•

Transfixation technique with K-wires is rarely used to treat metatarsal fractures.

Central metatarsal fractures: a review and current concepts

Central metatarsal fractures (CMF) are common injuries. More frequently fractures are those of the fifth metatarsal, followed by CMF and therefore by the first metatarsal. Third metatarsal is injured most frequently than the others and up to 63% is associated with second or fourth metatarsal fractures and up to 28% with both. Anatomy and metatarsal kinematics merits attention due to its influence on function, injuries and treatment options. Diagnosis is based on the history of trauma and clinical examination, relating with instrumental exams. Fractures with less than 10° of angulation and 3-4 mm of translation in any plane are typically treated conservatively, while operative treatment is generally reserved for fractures out if these values. Intramedullary fixation with K-wires seem to be the most common and valid surgical treatment in simple fractures. Spiral fractures should be treated by interfragmentary screws, which positioning may result difficult due to the adjacent metatarsals. Therefore, an alternative approach is an osteosynthesis with a dorsal plate. Multiple metatarsal fractures often occur in the contiguous bones, so clinicians will also have to carefully inspect metatarsals and adjacent joints such as Lisfranc articulation. The clinical and functional outcomes are often influenced by the pattern of fractures and patient conditions and are reported in the literature up to 39% of poor results.

Turf Toe and Disorders of the Sesamoid Complex

A turf toe injury encompasses a wide spectrum of traumatic problems that occur to the first metatarsophalangeal joint. Most of these injuries are mild and respond well to nonoperative management. However, more severe injuries may require surgical management, including presence of diastasis or retraction of sesamoids, vertical instability, traumatic hallux valgus deformity, chondral injury, loose body, and failed conservative treatment.

[Rheumatic forefoot deformities]

The frequency and extent of rheumatic forefoot deformities have been greatly reduced since the introduction of disease-modifying antirheumatic drugs (DMARD). The accompanying reduction in arthritic destruction of joints opens up new treatment options whereby priority is given to joint preservation. This is true for the first middle foot ray as well as for the small toe rays. Whereas resection arthroplasty of the metatarsophalangeal joints II-V was previously considered the gold standard treatment, joint-preserving operative procedures (e.g. metatarsal osteotomy and periarticular soft tissue interventions) are now being increasingly more propagated. Resection arthroplasty of the first midfoot ray has major biomechanical disadvantages so that it is not surprising that reconstructive procedures are given priority. In patients with severe arthritic destruction of the first metatarsophalangeal joint, arthrodesis has substantial biomechanical advantages compared to resection arthroplasty. Nevertheless, it has not yet been confirmed that fusion leads to superior clinical results.

Lower-limb amputations in patients with diabetes mellitus

It is estimated that approximately 23.6 million people in the United States have diabetes mellitus. With adequate control of this disease and appropriate foot care and basic surveillance, many patients can lead active and healthy lifestyles. However, some patients experience complications associated with poorly controlled glucose levels, including lower-extremity ulcerations and infections. When conservative measures have failed in treating these conditions, a lower-extremity amputation is an option for patients seeking to gain maximal functional recovery. A complete preoperative workup includes assessment of healing potential and preoperative ambulatory status, control or optimization of comorbidities when possible, and determination of amputation level using modern diagnostic modalities. Once the decision to proceed with an amputation has been made, it is important to choose an appropriate level of amputation and practice sound surgical technique. This article describes the preoperative evaluation and operative techniques involved in performing amputations on diabetic patients and reviews the current literature on the most common lower-extremity amputations performed in the care of infections in the feet of patients with diabetes mellitus.

Hallux IP arthritis after MP arthrodesis managed with interpositional arthroplasty of MP joint and IP fusion: case report

Salvage of foot with extensive giant cell tumour with transfer of vascularised fibular bone graft

Though giant cell tumor is not uncommon in young adults, simultaneous involvement of multiple mid-foot bones is very uncommon and very difficult to treat. For reconstruction of large segmental bony defects following tumour excision, free vascularized bone graft is an excellent surgical option. We report a case with extensive involvement of all the tarsal bones and metatarsal bases in a young adult. After excision his foot was reconstructed with vascularised bone flap. We were able to save his foot after a wide local excision and reconstruction with free fibula graft. Graft united early and showed excellent remodelling because of good vascularity. We feel that this method deserves consideration as a last attempt to salvage functional foot in disease like this.

Metatarsal fractures

Metatarsal fractures can present with a variety of situations. Ranging from the relatively benign, isolated central metatarsal fracture to the crush injury leading to extensive damage of the soft tissue and osseous components, these fractures can cause a significant inconvenience to the patient. With the exception of fifth metatarsal base fractures, little standardization is available for the treatment of metatarsal fractures. Controversy still exists regarding the proper treatment of various patient populations for junctional fifth metatarsal fractures. This article discusses the fractures of the first, central, and fifth metatarsals, as well as the treatment for the same.

Osteo-fasciocutaneous parascapular flap transfer for reconstruction of the first ray of the foot

BACKGROUND

Severe bone and soft tissue defects of the first metatarsal bone after trauma, tumor resection or osteomyelitis are challenging to treat. Partial amputation of the foot may be the consequence. However, due to its significance for gait, salvage of the first ray should be considered, whenever possible. One option for bone and soft tissue reconstruction, therefore, might be an osteo-fasciocutaneous parascapular flap transfer.

METHODS

Five patients with bone and soft tissue defects of the first ray of the foot but intact MTP joint were treated with osteo- fasciocutaneous parascapular flap transfer, two after tumor resection, and three after severe bone and soft tissue trauma. Patients were followed for 12-36 months clinically and radiologically.

RESULTS

All flaps survived. One revision was necessary because of venous thrombosis, which was treated successfully by thrombectomy and patch plastic. All osteosyntheses united and the scapular bone transplant adapted nicely to the new loading conditions. All patients were content with the result and would agree to have the operation again. Two patients were able to stand tiptoe and go jogging, one patient still had limitations of ADLs due to the concomitant injuries.

CONCLUSION

The osteo- fasciocutaneous flap proved to be very versatile and safe for foot reconstruction due to its favorable vascular anatomy. In all patients (partial), amputation of the foot could be avoided.

Hallux metatarsophalangeal joint fusion for the rheumatoid forefoot

Forefoot problems in patients who have rheumatoid arthritis are common. The progressive joint destruction causes a redistribution of weight about the forefoot, with a diminished weightbearing capacity of the first metatarsophalangeal (MTP) joint. Changes around the first MTP joint include synovitis, joint instability with subluxation, and arthritic change. Hallux MTP fusion in patients who have rheumatoid arthritis acts to permanently restore alignment and restore the medial column support of the foot, while at the same time enabling the first MTP to resume its original weightbearing role. Rheumatoid hallux MTP fusion and its rationale are reviewed.
