Is Reconstruction of Unstable Midfoot Charcot Neuroarthropathy Cost Effective from a US Payer's Perspective?

BACKGROUND: Charcot neuroarthropathy is a morbid and expensive complication of diabetes that can lead to lower extremity amputation. Current treatment of unstable midfoot deformity includes lifetime limb bracing, primary transtibial amputation, or surgical reconstruction of the deformity. In the absence of a widely adopted treatment algorithm, the decision to pursue more costly attempts at reconstruction in the United States continues to be driven by surgeon preference. QUESTIONS/PURPOSES: To examine the cost effectiveness (defined by lifetime costs, quality-adjusted life-years [QALYs] and incremental cost-effectiveness ratio [ICER]) of surgical reconstruction and its alternatives (primary transtibial amputation and lifetime bracing) for adults with diabetes and unstable midfoot Charcot neuroarthropathy using previously published cost data. METHODS: A Markov model was used to compare Charcot reconstruction and its alternatives in three progressively worsening clinical scenarios: no foot ulcer, uncomplicated (or uninfected) ulcer, and infected ulcer. Our base case scenario was a 50-year-old adult with diabetes and unstable midfoot deformity. Patients were placed into health states based on their disease stage. Transitions between health states occurred annually using probabilities estimated from the evidence obtained after systematic review. The time horizon was 50 cycles. Data regarding costs were obtained from a systematic review. Costs were converted to 2019 USD using the Consumer Price Index. The primary outcomes included the long-term costs and QALYs, which were combined to form ICERs. Willingness-to-pay was set at USD 100,000/QALY. Multiple sensitivity analyses and probabilistic analyses were performed to measure model uncertainty. RESULTS: The most effective strategy for patients without foot ulcers was Charcot reconstruction, which resulted in an additional 1.63 QALYs gained and an ICER of USD 14,340 per QALY gained compared with lifetime bracing. Reconstruction was also the most effective strategy for patients with uninfected foot ulcers, resulting in an additional 1.04 QALYs gained, and an ICER of USD 26,220 per QALY gained compared with bracing. On the other hand, bracing was cost effective in all scenarios and was the only cost-effective strategy for patents with infected foot ulcers; it resulted in 6.32 QALYs gained and an ICER of USD 15,010 per QALY gained compared with transtibial amputation. As unstable midfoot Charcot neuroarthropathy progressed to deep infection, reconstruction lost its value (ICER USD 193,240 per QALY gained) compared with bracing. This was driven by the increasing costs associated with staged surgeries, combined with a higher frequency of complications and shorter patient life expectancies in the infected ulcer cohort. The findings in the no ulcer and uncomplicated ulcer cohorts were both unchanged after multiple sensitivity analyses; however, threshold effects were identified in the infected ulcer cohort during the sensitivity analysis. When the cost of surgery dropped below USD 40,000 or the frequency of postoperative complications dropped below 50%, surgical reconstruction became cost effective. CONCLUSIONS: Surgeons aiming to offer both clinically effective and cost-effective care would do well to discuss surgical reconstruction early with patients who have unstable midfoot Charcot neuroarthropathy, and they should favor lifetime bracing only after deep infection develops. Future clinical studies should focus on methods of minimizing surgical complications and/or reducing operative costs in patients with infected foot ulcers.

A high-profile thread with grit-blasted and acid-etched surface reduces loosening of medial column fusion bolt in instable Charcot foot.

BACKGROUND: Intramedullary fusion bolts (FB) were introduced to stabilize the medial column of the instable Charcot foot (ICF), but complications as bolt loosening or breakage are frequent. We compared the use of a standard FB and a high-profile threaded FB with a grit-blasted surface. We hypothesized that implant related complications occurred less often and osseous consolidation of fusion sites was more distinctive using the latter type of FB. METHODS: Consecutive patients suffering from an ICF were stabilized with a high-profile threaded and surface-modified FB (HTFB) (n=20) or with a standard FB (n=20) which was placed into the first ray. Additional bolts and dorsal low-profile plates were applied in every patient. In a retrospective assessment osseous consolidation of the fusion sites was analyzed at 3 month and quantified by CT scan. At 3 and 12 month longitudinal foot arch collapse and rate of bolt loosening were assessed. RESULTS: Compared to the control group, the HTFB group reached significant higher consolidation after 3 month. No dislocation and a single bolt breakage was observed in the HTFB group after the fourth month, while the control group included 3 patients with bolt dislocation at 3±1 month and 5 patients with bolt breakage at 6±1.8 month. Compared to preoperative values, the improvement of Meary's angle after one-year was significant higher in the HTFB group (23.4°±14) than in controls (11.7°±13). CONCLUSIONS: Modification of bolt design improves the stability of the medial column: A higher rate of osseous consolidation of the medial column leads to lower rate of bolt dislocation/breakage and finally to permanently erected longitudinal foot arch. Initially disappointing results following medial column stabilization with fusion bolts can be rejected by modifications of bolt design and its technical application.

Radiologic Evaluation of Lower Leg, Ankle, and Foot Fracture Fixation Hardware.

Radiologists should be familiar with basic principles of fracture fixation and the normal imaging appearances of implant constructs and their complications. The surgeon's selection of external fixation, intramedullary nail fixation, open reduction and internal fixation, or some combination depends on patient factors, fracture configuration, injury to the soft tissue envelope, and surgeon experience. Complications including loss of fixation with resultant malalignment, nonunion, infection, and posttraumatic osteoarthritis present additional challenges for the surgeon as well as the radiologist. This article reviews the rationale behind fracture fixation in fractures of the lower leg, ankle, and foot. Examples of postoperative complications are also reviewed.

Lateral column lengthening versus subtalar arthroereisis for paediatric flatfeet: a systematic review.

PURPOSE: This systematic review aimed to compare radiographic correction, clinical outcomes, complications, and re-operations between lateral column lengthening (LCL) and arthroereisis (AR) for treating symptomatic flatfoot in children. METHODS: We conducted a comprehensive search on MEDLINE, EMBASE, and Cochrane Library databases. Literature search, data extraction, and quality assessment were conducted by two independent reviewers. The outcomes analyzed included radiographic parameters, clinical scores, satisfaction, complications, and re-operations. RESULTS: Twenty-one and 13 studies were included in the LCL and AR groups, respectively. The change in anteroposterior talo-first metatarsal angle was greater in the LCL (9.5° to 21.7°) than in the AR group (10.6° to 12.8°). The change in calcaneal pitch was greater in the LCL (2.1° to 26.53°) than in the AR group (- 1.3° to 3.23°). Improvements in the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were greater in the LCL (27.7 to 39.1) than in the AR group (17 to 22). The percentage of satisfaction was similar between the LCL (68% to 89%) and AR (78.5% to 96.4%) groups. The complication rate was higher in the LCL (0% to 86.9%) than in the AR group (3.5% to 45%). The most common complications were calcaneocuboid subluxation and persistent pain in the LCL and AR groups, respectively. The re-operation rate was similar between the LCL (0% to 27.3%) and AR (0% to 36.4%) groups. CONCLUSIONS: The LCL group has achieved more radiographic corrections and more improvements in the AOFAS score than the AR group. Complications were more common in the LCL group than in the AR group, and the re-operation rates were similar between the two groups.

Treatment of complex foot deformities with hexapod external fixator in growing children and young adult patients.

BACKGROUND: Treatment of complex foot deformities in growing children and young adult patients is challenging. The traditional approach consists of extensive soft tissues releases, osteotomies and/or arthrodesis. More recently, distraction osteogenesis has been proposed as an alternative strategy. The aim of this study was to describe our treatment strategy and report clinical outcomes of the patients affected from complex foot deformities treated by distraction osteogenesis and hexapod external fixator. MATERIALS AND METHODS: We retrospectively reviewed 10 consecutive patients with complex foot and ankle deformities treated from 2014 to 2016 at our unit. A TrueLok external fixator system was used in all patients. Final outcome was classified as good, fair and poor according to the criteria indicated by Paley and Ferreira. The results were also evaluated by the pre-operative and post operative American Orthopedic Foot and Ankle Score (AOFAS) and The Manchester-Oxford Foot Questionnaire (MOXFQ). RESULTS: A plantigrade foot was obtained in eight patients at the end of treatment, while in two patients a recurrence of the deformity was noted. Result was classified as good in 6 patients, fair in 2 patients, and poor in 2 patients. The AOFAS score improved from 33.9±21.2 pre-operatively to 67.25±15.1 post-operatively (p=0.005). A statistically significant improvement was observed for the MOXFQ score as well (from 60.6±23.3 to 33.0±25.2, p=0.020). CONCLUSIONS: Our study shows that the TrueLok hexapod external fixator is a safe and effective tool in treatment of complex rigid foot deformities. Nevertheless, deformity recurrence can be observed in some cases and treatment remains challenging. Distraction osteogenesis should be reserved as a salvage solution for particularly complex cases and should be performed at dedicated specialized centers.

Surgical Management of Stage 2 Adult and Pediatric Acquired Flatfoot Without Tendon Transfer or Arthrodesis: A Retrospective Study.

Posterior tibial tendon dysfunction (PTTD) is a common pathology of the foot and ankle. Numerous techniques are available to reconstruct the flatfoot. Fusions and tendon transfers are popular methods; however, a wide range of complications have been associated with these procedures. The objective of the present study was to demonstrate the outcomes of reconstructive surgery for flatfoot correction without tendon transfer or arthrodesis. We performed a retrospective study of 43 patients and 56 feet who had undergone flatfoot reconstructive surgery from November 2011 to June 2016, with a mean follow-up period of 60 weeks (range 12 to 60 months). Each patient demonstrated a stage 2 flatfoot deformity classified using the Johnson and Strom classification. Depending on the patient's deformity, the procedures consisted of different variations of gastrocnemius recession, medial displacement calcaneal osteotomy, Evans osteotomy, and Cotton osteotomy. Six different preoperative and postoperative angles were radiographically measured on each foot studied. In all cases, the differences in the preoperative versus postoperative measurements were statistically significant (p < .003). We believe the foot and ankle surgeon can correct flatfoot deformity with the use of extraarticular procedures and create a plantigrade functional foot without fusion or tendon transfer.

Comparison of postoperative pain control methods after bony surgery in the foot and ankle.

BACKGROUND: We performed a prospective study to evaluate and compare the effectiveness of postoperative pain control methods after bone surgery in the foot and ankle. METHODS: Among the patients who underwent foot and ankle surgery from June 2014 to September 2015 with an ultrasound-guided nerve block, 84 patients who fully completed a postoperative pain survey were enrolled. An opioid patch (fentanyl patch, 25mg) was applied in group A (30 patients). Diluted anesthetic (0.2% ropivacaine, 30ml) was injected into the sciatic nerve once, about 12h after the preoperative nerve block, in group B (27 patients). Periodic intramuscular injection of an analgesic (ketorolac [Tarasyn], 30mg) was performed in group C (27 patients). The visual analogue scale (VAS) pain scores at 6, 12, 18, 24, and 48h after surgery were checked, and the complications of all methods were monitored. RESULTS: The mean VAS pain score was lower in group B, with a statistically significant difference (P<.05) between groups A, B, and C at 12 and 18h after surgery. Four patients in group A experienced nausea and vomiting; however, no other patients complained of any complications or adverse effects. CONCLUSION: The ultrasound-guided injection of a diluted anesthetic into the sciatic nerve seemed to be the most useful method for controlling pain in the acute phase after bone surgery in the foot and ankle. The injection of the diluted anesthetic once on the evening of the day of surgery resulted in less postoperative pain in the patients. LEVEL OF EVIDENCE: II.

Osteoid osteoma of the hand and foot in children successfully treated with radiofrequency neurotomy probes.

Osteoid osteoma is a common benign tumor that is typically found in young adults and children, usually in the long bones of the lower extremity. Radiofrequency ablation (RFA) under computed tomography guidance is the standard of care for symptomatic osteoid osteomas. However, patients with osteoid osteoma of the hand or foot are often treated with open surgery because of the risk of injury to vascular and neural structures from RFA. This risk is more pronounced in pediatric patients because of the small lesion size and proximity of lesions to important neurovascular structures. Here, we present 2 pediatric patients, one with an osteoid osteoma in the hand and the other with an osteoid osteoma in the foot. In both patients, a 22-gauge, 2.5-mm active tip ablation probe was used. The smaller ablation volume achieved with this probe protected neighboring neurovascular structures while effectively ablating the osteoid osteoma nidus. Based on our success in these cases, we recommend the application of this method for cases in which neurovascular proximity to the osteoid osteoma lesion makes ablation challenging.

Primary Tumor and Tumor-Like Lesions of Bones of the Foot: Single-Center Experience of 166 Cases.

Primary bone tumors of the foot are rare lesions. The purpose of the present study was to evaluate the clinical manifestations, treatment modalities, and recurrences of various primary bone tumors of the foot from a specialized center for orthopedic oncology. Among 3681 musculoskeletal tumor cases, which were diagnosed and surgically treated in our hospital from 1983 to 2013, 166 primary tumor and tumor-like bone lesions of the foot (4.5%) were retrospectively reviewed regarding age, gender, localization, biopsy-revealed diagnosis, applied treatment modalities, follow-up period, and recurrence, if any. Of the 166 primary bone tumors of the foot, 155 (93.4%) were benign and 11 (6.6%) were malignant. The most common primary benign bone tumor was a unicameral bone cyst (57 of 155; 36.8%), and the most common malignant tumor was chondrosarcoma (7 of 11; 63.6%). The hindfoot was the most common location for both primary benign (104 of 155; 67.1%) and malignant (6 of 11; 54.5%) bone tumors of the foot. The results of our study have confirmed that the radiologic findings can be confusing owing to the structural and histopathologic features of the bones of the foot; thus, histopathologic diagnosis should be considered for foot involvement. Because the characteristics of the compartments in the foot allow for the rapid spread of malignant lesions, aggressive surgical management and wider resection are recommended to prevent recurrence and further spread.

Lisfranc Injury Imaging and Surgical Management.

The Lisfranc joint is composed of the cuneiform bones and the cuboid and metatarsal bases, united by a synovial capsule and ligamentous complex. Familiarity with the anatomy is essential for image planning and for understanding injury patterns. The more important structures are the Lisfranc ligament and the plantar ligaments that can be visualized with MR, although careful attention to technique and orientation of scan planes is required for accuracy. A combination of conventional radiographs, computed tomography, and MR allow precise diagnosis of Lisfranc fractures, fracture dislocation, and subtle Lisfranc injuries to guide clinical management and surgical planning.

Does Open Reduction and Internal Fixation versus Primary Arthrodesis Improve Patient Outcomes for Lisfranc Trauma? A Systematic Review and Meta-analysis.

BACKGROUND: Although Lisfranc injuries are uncommon, representing approximately 0.2% of all fractures, they are complex and can result in persistent pain, degenerative arthritis, and loss of function. Both open reduction and internal fixation (ORIF) and primary fusion have been proposed as treatment options for these injuries, but debate remains as to which approach is better. QUESTIONS/PURPOSES: We asked whether ORIF or primary fusion led to (1) fewer reoperations for hardware removal; (2) less frequent revision surgery; (3) higher patient outcome scores; and (4) more frequent anatomic reduction. METHODS: A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Three trials met the criteria for inclusion within the meta-analysis. Qualifying articles for the meta-analysis had data extracted independently by two authors (NS, AF). The quality of each study was assessed using the Center for Evidence Based Medicine's evaluation strategy; data were extracted from articles rated as good and fair: two and one article, respectively. RESULTS: The risk ratio for hardware removal was 0.23 (95% confidence interval [CI], 0.11-0.45; p < 0.001) indicating more hardware removal for ORIF than fusion. For other revision surgery, the risk ratio for ORIF was 0.36 (95% CI, 0.08-1.59; p = 0.18) favoring neither. Similarly, neither was favored using patient-reported outcomes; the standard mean difference was calculated to be 0.50 (95% CI, -2.13 to 3.12; p = 0.71). When considering the risk of nonanatomic alignment, neither was favored (risk ratio, 1.48; 95% CI, 0.34-6.38; p = 0.60). CONCLUSIONS: The surgeon should consider the increased risk of hardware removal along with its associated morbidity and discuss this with the patient preoperatively when considering ORIF of Lisfranc injuries. Because no new trials have been performed since 2012, further randomized controlled trials will be needed improve our understanding of these interventions.

Reconstruction of midfoot bone and soft tissue loss with chimeric partial scapula and latissimus dorsi muscle flap and short perforator-based skin flap following gunshot injuries: Report of two cases.

INTRODUCTION: In this report we present two cases of gunshot injury related midfoot defects, reconstructed with a chimeric partial scapula and latissimus dorsi muscle flap and short perforator-based skin flap. The first case, a 14 years old male, had 10 × 8 cm medial plantar and 6 × 4 cm dorsal foot defects and the second case, a 55 years old female, had only 8 × 6 cm dorsal foot defect. In both cases the defects were associated with fractures, one with lateral cuneiform and cuboid with 90% bone loss and the other with navicular bone, respectively. After 6 months, the patients could walk well without support, and radiographs confirmed bony union. A chimeric partial scapula and latissimus dorsi muscle flap and short perforator-based skin flap may be used for the reconstruction of combined bony and soft tissue defects of the midfoot and to promote bone healing. © 2016 Wiley Periodicals, Inc.

Medial and Lateral Plantar Artery Angiosome Rotational Flaps for Transmetatarsal and Lisfranc Amputation in Patients With Compromised Plantar Tissue.

Traditional incision techniques for midfoot amputation might not provide immediate soft tissue coverage of the underlying metatarsal and tarsal bones in the presence of a large plantar soft tissue defect. Patients undergoing transmetatarsal and Lisfranc amputation frequently have compromised plantar tissue in association with neuropathic ulcers, forefoot gangrene, and infection, necessitating wide resection as a part of the amputation procedure. Open amputation will routinely be performed under these circumstances, although secondary healing could be compromised owing to residual bone exposure. Alternatively, the surgeon might elect to perform a more proximal lower extremity amputation, which will allow better soft tissue coverage but compromises function of the lower extremity. A third option for this challenging situation is to modify the plantar flap incision design to incorporate a medial or lateral plantar artery angiosome-based rotational flap, which will provide immediate coverage of the forefoot and midfoot soft tissue defects without excessive shortening of the bone structure. A plantar medial soft tissue defect is treated with the lateral plantar artery angiosome flap, and a plantar lateral defect is treated with the medial plantar artery angiosome flap. Medial and lateral flaps can be combined to cover a central plantar wound defect. Incorporating large rotational flaps requires knowledge of the applicable angiosome anatomy and specific modifications to incision planning and dissection techniques to ensure adequate soft tissue coverage and preservation of the blood supply to the flap. A series of 4 cases with an average follow-up duration of 5.75 years is presented to demonstrate our patient selection criteria, flap design principles, dissection pearls, and surgical staging protocol.

Intercuneiform and Lisfranc Fracture-Dislocation Due to Seizure: A Case Report.

Cuneiform dislocation associated with Lisfranc injury is a very rare injury. Dislocation over the midfoot due to a seizure has not been previously reported in published studies. A 35-year-old female presented with an intercuneiform dislocation and Lisfranc fracture-dislocation after a generalized seizure. Immediate close reduction of the dorsally dislocated cuneiforms was performed, followed by definitive treatment to restore the foot arches. A proposed underlying pathophysiology of dislocation due to seizure in terms of the biomechanics is discussed. The purpose of our report was to present the unusual etiology of this form of cuneiform dislocation and Lisfranc joint complex injury.

Staphylococcus lugdunensis: A Rare Pathogen for Osteomyelitis of the Foot.

Staphylococcus lugdunensis is an aggressive gram-positive bacteria that can lead to devastating infections in humans. S. lugdunensis has been associated with rare cases of osteomyelitis of the vertebra, prosthetic implants, and endocarditis. Reports of this organism associated with osteomyelitis of the foot or ankle have been infrequent. We present a unique case of acute osteomyelitis of a foot caused by S. lugdunensis after a patient stepped on a thorn. Our case is unique, because the radiographic changes were noted within 4 days, despite normal plain films and magnetic resonance images on the day of admission. This finding suggests the aggressiveness and virulence of S. lugdunensis. In addition, we report the first case of foot osteomyelitis as a result of isolated S. lugdunensis that involved 2 distinct specimens with 2 different antibiotic sensitivity reports.

Ostectomy and Medial Plantar Artery Flap Reconstruction for Charcot Foot Ulceration Involving the Midfoot.

Charcot foot is a serious complication of diabetes, characterized by deformity and overlying ulceration. The condition most commonly affects the midfoot. However, little information is available on the use of a medial plantar artery flap to treat diabetic midfoot ulceration. The purpose of the present study was to evaluate the versatility of ostectomy and medial plantar flap reconstruction for midfoot plantar ulceration associated with rocker-bottom deformity secondary to Charcot foot. Four patients underwent ostectomy and medial plantar flap reconstruction. Before flap reconstruction, the devitalized soft tissues and bone were radically resected. After the infection had been controlled, the ulcerated portion was minimally excised, and the bony prominence underlying the ulcer was removed. A medial plantar artery flap was applied to the ulcer. The donor site was covered with a split-thickness skin graft or artificial dermis. In all patients, the ulcers healed and independent ambulation was achieved. However, 1 patient experienced ulcer recurrence, and subsequent infection necessitated a major amputation. Limb salvage is challenging in the setting of deformity and intractable plantar ulceration. The advantages of medial plantar artery flap reconstruction are that tissues with a rich blood supply are used to cover the exposed bone, and the flap can withstand the pressure and shear stress of the patient's body weight. However, a dominant artery in the foot is sacrificed. Therefore, the patency of the dorsalis pedis artery must be confirmed in every patient. The results of the present study have demonstrated that a medial plantar artery can be an effective alternative for diabetic patients with a plantar ulcer secondary to Charcot foot.

[Hindfoot fusion for Charcot osteoarthropathy with a curved retrograde nail]. / Rückfußarthrodese beim Charcot-Fuß mit retrogradem Nagel.

BACKGROUND: Charcot osteoarthropathy of the hindfoot with considerable dislocation and instability represents a therapeutic dilemma. The treatment goal is a plantigrade, stable foot that is free of infection and ulceration with the ability to ambulate in special footwear. MATERIALS AND METHODS: Over a period of 6 years, we performed 23 hindfoot fusions in 21 patients with manifest Charcot arthropathy with the help of a curved retrograde nail (HAN). All patients suffered from insulin-dependent diabetes mellitus with polyneuropathy; 12 patients had additional peripheral vasculopathy. An average of 3.5 previous surgeries had been performed prior to hindfoot fusion. RESULTS: Complete tibiotalocalcaneal fusion was obtained in 16 of 21 patients (76 %). Of these 21 patients, 18 (86 %) were followed clinically and radiologically for an average of 2 years. Overall, 16 patients (89 %) reported a substantial subjective improvement compared to the preoperative state. Hardware failure occurred in 7 cases (30 %) that could be brought to consolidation with exchange of the locking bolts or the complete nail. In 5 cases (22 %), a postoperative hematoma had to be removed and in 8 cases (35 %) wound edge necrosis was treated with local wound care. In 2 cases (9 %), a secondary or reactivated osteitis occurred that finally required below knee amputation. CONCLUSION: Tibiotalocalcaneal fusion with a curved retrograde intramedullary nail (HAN) is an effective treatment option in highly unstable and deforming Charcot osteoarthropathy of the hindfoot. It is an alternative to external or other internal fixation methods and helps to avoid below knee amputation in more than 90 % of cases.

Development of a Radiographic Union Score for Determining Osteotomy Union Rates in Long Bones of the Foot.

Determining the status of bone healing after osteotomy can be challenging and has implications ranging from clinical decision-making to standardization of research outcomes without the use of computed tomography. To date, no method has been validated for determining osseous healing of an osteotomy site of the long bones of the foot. The purpose of the present study was to develop a radiographic union scoring system that would enhance the diagnostic healing assessment. We adapted existing orthopedic scales that had been validated for healing in the leg for application in the long bones of the foot. One hundred cases were evaluated by 6 blinded assessors to test the inter- and intrarater reliability of the subjective healing assessment compared with the proposed scoring system. The radiographs were classified by postoperative period: ≤4, 5 to 12, and >12 weeks. The proposed scale had a high interrater reliability but was burdensome. Using a priori item reduction protocols, the scale was limited to the 5 items with the best internal consistency, which significantly reduced the burden. The result was excellent interrater reliability (α = 0.87) among all assessors compared with acceptable reliability (α = 0.66) for the subjective osteotomy healing assessment. The intrarater reliability during the subsequent retest phase demonstrated similar relationships, with low agreement (r = 0.38) for subjective healing. Each of the items included in the final scoring scale had moderate to good agreement across all assessors (r = 0.51 to 0.63). The reliability of this system appeared superior to the subjective assessment of osseous healing alone, even in the absence of clinical correlates after an osteotomy in the foot.

[A Clinical Comparison of Continuous Sciatic Nerve Block and Epidural Anesthesia for Postoperative Pain Control in Patients with Fracture of the Foot].

BACKGROUND: Epidural analgesia provides good pain relief for patients with fracture of the foot Ultrasound-guided peripheral nerve block offers safety and efficacy without affecting the leg. METHODS: We compared the continuous sciatic nerve block with the continuous epidural anesthesia regarding postoperative pain after the open reduction and internal fixation (ORIF) of the ankle fracture or calcaneal bone fracture. RESULTS: Fifteen patients were included in the epidural group (group E), and 17 patients in the sciatic nerve block group (group S). The postoperative pain scores were significantly lower in group S 3 hours and 12 hours after the procedure, and tended to be lower in other periods. Perioperative periods were uneventful in both groups. CONCLUSIONS: Continuous sciatic nerve block developed good postoperative analgesia in ORIF of ankle fracture or calcaneal bone fracture compared with continuous epidural anesthesia.

[Reconstructions after inveterated fractures and dislocations of the foot]. / Rekonstruktionsmaßnahmen nach veralteten Frakturen und Luxationen des Fußes.

Inveterated fractures or dislocations of the foot which are defined as being more than 6-12 weeks old can be secondarily reconstructed anatomically in only very rare cases. All other cases need reorientation of all axes of the foot requiring single or combined joint fusion. In cases of significant posttraumatic bone necrosis the dead bone has to be radically resected and substituted by an autogenous bone graft from the iliac crest. Old cases of dislocation, for example after subtalar dislocation without anatomical reduction, need reorientation of the foot axes by performing arthrodesis. Subluxation of the medial Lisfranc joint after an unrecognized rupture of Lisfranc ligament can be controlled later by anatomical repair of this ligament by using half of the extensor digitorum longus tendon and thus avoiding arthrodesis.
