The coronavirus disease of 2019 pandemic has disrupted health care, with its far-reaching effects seeping into chronic disease evaluation and treatment. Our tertiary wound care center was specially designed to deliver the highest quality care to wounded patients. Before the pandemic, we were able to ensure rapid treatment by means of validated protocols delivered by a colocalized multidisciplinary team within the hospital setting. The pandemic has disrupted our model’s framework, and we have worked to adapt our workflow without sacrificing quality of care. Using the modified Donabedian model of quality assessment, we present an analysis of prepandemic and intrapandemic characteristics of our center. In this way, we hope other providers can use this framework for identifying evolving problems within their practice so that quality care can continue to be delivered to all patients.
Background: Tarsal tunnel syndrome (TTS) can be divided into proximal TTS and distal TTS (DTTS). Research on methods to differentiate these two syndromes is sparse. A simple test and treatment is described as an adjunct to assist with diagnosing and providing treatment for DTTS.
Methods: The suggested test and treatment is an injection of lidocaine mixed with dexamethasone administered into the abductor hallucis muscle at the site of entrapment of the distal branches of the tibial nerve. This treatment was studied with a retrospective medical record review in 44 patients with clinical suspicion of DTTS.
Results: The lidocaine injection test and treatment (LITT) was positive in 84% of patients. Of patients available for follow-up evaluation (35), 11% of those with a positive LITT test (four) had complete lasting symptom relief. One-quarter of patients with initial complete symptom relief at LITT administration (four of 16) maintained this level of symptom relief at follow-up. Thirty-seven percent of patients evaluated at follow-up (13 of 35) who had a positive response to the LITT experienced partial or complete symptom relief. No association was found between level of symptom relief maintenance and the immediate level of symptom relief (Fisher exact test = 0.751; P = .797). The results showed no difference in the distribution of immediate symptom relief by sex (Fisher exact test = 1.048; P = .653).
Conclusions: The LITT is a simple, safe, invasive method to help diagnose and treat DTTS, and it provides an additional method to assist with differentiating DTTS from proximal TTS. The study also provides additional evidence that DTTS has a myofascial etiology. The proposed mechanism of action of the LITT suggests a new paradigm in diagnosing muscle-related nerve entrapments that may lead to nonsurgical treatments or less invasive surgical interventions for DTTS.
Background: Lipomas, derived from adipose tissue, most frequently occur in the cephalic regions and proximal extremities, but rarely in the toes. We aimed to highlight the clinical features, diagnosis, and treatment of lipomas of the toes.
Methods: We analyzed 8 patients with lipomas of the toes who were diagnosed and treated during a 5-year period.
Results: Lipomas of the toes were equally distributed by sex. Patients ranged in age from 28 to 67 years (mean age, 51.75 years). Six patients (75%) had a single lesion, and all of the patients developed lipomas on the hallux. Most patients (75%) presented with a painless, subcutaneous, slow-growing mass. The duration from symptom onset to surgical excision ranged from 1 month to 20 years (mean, 52.75 months). Lipoma size varied from 0.4 to 3.9 cm in diameter (mean, 1.6 cm). Magnetic resonance imaging showed a well-encapsulated mass with hyperintense signal on T1-weighted images and hypointense signal on T2-weighted images. All of the patients were treated with surgical excision, and no recurrences were found at mean follow-up of 38.5 months. Six patients were diagnosed as having typical lipomas, one a fibrolipoma, and one a spindle cell lipoma, which needs to be differentiated from other benign and malignant lesions.
Conclusions: Lipomas of the toes are rare, slow-growing, painless, subcutaneous tumors. Men and women are equally affected, usually in their 50s. Magnetic resonance imaging is the favored modality for presurgical diagnosis and planning. Complete surgical excision is the optimal treatment, with rare recurrence.
Background: Arch pain in athletes is a common complaint with many causes. One uncommon cause of arch pain related to exercise that is often overlooked is chronic exertional compartment syndrome. This diagnosis should be considered in athletes who presents with exercise-induced foot pain. Recognition of this problem is paramount because it can significantly affect an athlete’s ability to pursue further sports activities.
Methods: Three case studies are presented that underscore the importance of a comprehensive clinical evaluation. Unique historical information and findings on focused physical examination after exercise strongly suggest the diagnosis.
Results: Intracompartment pressure measurements before and after exercise are confirmatory. Because nonsurgical care is typically palliative, surgery involving fasciotomy to decompress involved compartments can be curative and is described in this article.
Conclusions: These three cases with long-term follow-up were randomly chosen and are representative of the authors’ combined experience with chronic exertional compartment syndrome of the foot.
Background: Diabetic foot infections (DFIs) can lead to limb loss and mortality. To improve patient care at a safety-net teaching hospital, we created a multidisciplinary limb salvage service (LSS).
Methods: We recruited a cohort prospectively and compared it to a historical control group. Adults admitted to the newly established LSS for DFI during a 6-month period from 2016 to 2017 were included prospectively. Patients admitted to the LSS had routine endocrine and infectious diseases consultations according to a standardized protocol. A retrospective analysis of patients admitted to the acute care surgical service for DFI before creation of the LSS during an 8-month period from 2014 to 2015 was performed.
Results: A total of 250 patients were divided into two groups: the pre-LSS (n = 92) and the LSS (n = 158) groups. There were no significant differences in baseline characteristics. Although all patients were ultimately diagnosed with diabetes, more patients in the LSS group had hypertension (71% versus 56%; P = .01) and a prior diagnosis of diabetes mellitus (92% versus 63%; P < .001) compared to the pre-LSS group. Significantly, with the LSS, fewer patients underwent a below-the-knee amputation (3.6% versus 13%; P = .001). There was no difference in the length of hospital stay or 30-day readmission rate between the groups. Further broken down into Hispanic versus non-Hispanic, we noted that Hispanics had significantly lower rates of below-the-knee amputations (3.6% versus 13.0%; P = .02) in the LSS cohort.
Conclusions: The initiation of a multidisciplinary LSS decreased the below-the-knee amputation rate in patients with DFIs. Length of stay was not increased, nor was the 30-day readmission rate affected. These results suggest that a robust multidisciplinary LSS dedicated to the management of DFIs is both feasible and effective, even in safety-net hospitals.
The first metatarsophalangeal joint is the most common location for arthritis in the foot. Pain and limited mobility associated with arthritis of the first metatarsophalangeal joint are the hallmarks of this disease. Treatments include shoe modification, orthotic devices, nonsteroidal anti-inflammatory drugs, injections, physical therapy, and surgery. Surgery has been the most perplexing, with surgical treatments ranging from simple ostectomies to fusion of the first metatarsophalangeal joint. Implant arthroplasty, with its various designs and techniques, has yet to be proven as the definitive solution for first metatarsophalangeal joint arthritis or hallux limitus (unlike the knee and hip). Interpositional arthroplasty and tissue-engineered cartilage grafts also have limitations when dealing with osteoarthritis and hallux limitus of the first metatarsophalangeal joint. In this case report, we present a 45-year-old woman with arthritis of the left first metatarsophalangeal joint who underwent surgical intervention by means of a frozen osteochondral allograft transplant to the first metatarsal head.
Background: Hallucal sesamoid injuries occur in approximately 5% to 10% of foot and ankle injuries. Most cases can be treated conservatively. However, when nonoperative management fails, surgical intervention is warranted.
Methods: The present case involved a 17-year-old female high school senior who presented to the clinic with right hallux pain. Radiographs were obtained and revealed congenital absence of the fibular sesamoid and evidence of a minimally displaced avulsion fracture involving the proximal medial tibial sesamoid. Treatment was complicated by the congenital absence of the fibular sesamoid and by a high activity level.
Results: After conservative treatment failure, the patient underwent partial excision of her tibial sesamoid. She was followed for 1.5 years after initial presentation to our clinic. The patient was able to return to daily activities; however, she was not able to return to softball competitively due to pain.
Conclusions: We hypothesize she was unable to return to softball because the absence of a sesamoid can decrease push-off strength. We recommend that providers treating athletes educate their patients on the possible loss of strength and take this into account when creating a treatment plan.
Plantar thrombophlebitis is a rare abnormality with few cases reported in the literature. Coexistence with severe acute respiratory syndrome coronavirus 2 infection increases its relevance. The disease is generally classified as idiopathic, and it is suggested that it is attributed to conditions that lead to hypercoagulability. We present the case of a 68-year-old female patient with thrombosis of the lateral plantar veins and a diagnosis of coronavirus disease of 2019. The plantar vein thrombosis diagnosis was made by means of Doppler ultrasonography and magnetic resonance imaging. Severe acute respiratory syndrome coronavirus 2 infection was suspected per clinical information and confirmed with reverse-transcriptase polymerase chain reaction technique. Treatment was successful using rivaroxaban and nonsteroidal antiinflammatory drugs.
Precalcaneal congenital fibrolipomatous hamartomas are rare benign lesions that present in infancy. Lesions typically appear as unilateral or bilateral skin-colored asymptomatic subcutaneous nodules on the precalcaneal plantar heel. Diagnosis is clinical, and operative intervention is not indicated unless lesions are symptomatic. We report two cases of subcutaneous plantar nodules diagnosed as precalcaneal congenital fibrolipomatous hamartomas. The aim is to raise awareness of this rare diagnosis and emphasize its benign nature and conservative management.
