Digital foot trauma: emergency diagnosis and treatment

Staged reconstruction of the hallux for infected non-union using bulk autograft and a customized implant: Case report

This case report illustrates the outcome of a deep infection following internal fixation of a fracture of the big toe. Hallux amputation could be avoided through staged salvage procedure. This paper can assist readers on how to effectively and safely recognize and treat this type of injury.

Return to sport following toe phalanx fractures: A systematic review

BACKGROUND

Evidence-based guidance on return to sport following toe phalanx fractures is limited.

AIM

To systemically review all studies recording return to sport following toe phalanx fractures (both acute fractures and stress fractures), and to collate information on return rates to sport (RRS) and mean return times (RTS) to the sport.

METHODS

A systematic search of PubMed, MEDLINE, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database, and Google Scholar was performed in December 2022 using the keywords ‘Toe’, ‘Phalanx’, ‘Fracture’, ‘injury’, ‘athletes’, ‘sports’, ‘non-operative’, ‘conservative’, ‘operative’, ‘return to sport’. All studies which recorded RRS and RTS following toe phalanx fractures were included.

RESULTS

Thirteen studies were included: one retrospective cohort study and twelve case series. Seven studies reported on acute fractures. Six studies reported on stress fractures. For the acute fractures (n = 156), 63 were treated with primary conservative management (PCM), 6 with primary surgical management (PSM) (all displaced intra-articular (physeal) fractures of the great toe base of the proximal phalanx), 1 with secondary surgical management (SSM) and 87 did not specify treatment modality. For the stress fractures (n = 26), 23 were treated with PCM, 3 with PSM, and 6 with SSM. For acute fractures, RRS with PCM ranged from 0 to 100%, and RTS with PCM ranged from 1.2 to 24 wk. For acute fractures, RRS with PSM were all 100%, and RTS with PSM ranged from 12 to 24 wk. One case of an undisplaced intra-articular (physeal) fracture treated conservatively required conversion to SSM on refracture with a return to sport. For stress fractures, RRS with PCM ranged from 0% to 100%, and RTS with PCM ranged from 5 to 10 wk. For stress fractures, RRS with PSM were all 100%, and RTS with surgical management ranged from 10 to 16 wk. Six cases of conservatively-managed stress fractures required conversion to SSM. Two of these cases were associated with a prolonged delay to diagnosis (1 year, 2 years) and four cases with an underlying deformity [hallux valgus (n = 3), claw toe (n = 1)]. All six cases returned to the sport after SSM.

CONCLUSION

The majority of sport-related toe phalanx fractures (acute and stress) are managed conservatively with overall satisfactory RRS and RTS. For acute fractures, surgical management is indicated for displaced, intra-articular (physeal) fractures, which offers satisfactory RRS and RTS. For stress fractures, surgical management is indicated for cases with delayed diagnosis and established non-union at presentation, or with significant underlying deformity: both can expect satisfactory RRS and RTS.

Management of acute lesser toe pain

Patients with foot pain commonly present to their primary care physicians for their initial management and treatment. These patients and their respective foot or lesser toe pain can present the physician with a complex problem with a long differential list. Depending on the timing of the pain and underlying pathology, these differentials can be divided into acute and acute exacerbation of chronic conditions. This review categorizes the history, physical exam, radiological findings, conservative treatment, and surgical management for each major cause of lesser toe pain, whether acute or chronic. The acute conditions surrounding lesser toe pain in the adult population discussed are toe fractures, toe dislocations, and metatarsal head and neck fractures. The chronic pathologies surrounding lesser toe pain in the adult population evaluated in this review include metatarsalgia, Morton's neuroma, Freiberg infraction, brachymetatarsia, bunionettes, and lesser toe disorders.

ACR Appropriateness Criteria® Acute Trauma to the Foot

Acute injuries to the foot are frequently encountered in the emergency room and in general practice settings. This publication defines best practices for imaging evaluations for several variants of patients presenting with acute foot trauma. The variants include scenarios when the Ottawa rules can be evaluated, when there are exclusionary criteria, and when suspected pathology is in anatomic areas not addressed by the Ottawa rules. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Do Broken Toes Need Follow-Up in the Fracture Clinic?

Most toe phalangeal fractures can be successfully treated nonoperatively without any residual deformity and are usually clinically asymptomatic. Toe phalangeal fractures are nevertheless common fracture clinic referrals. Our aim was to evaluate the injury characteristics of patients with toe fractures attending a fracture clinic and to understand how current management affects the fracture clinic workload. We retrospectively evaluated all new referrals to a subspecialized foot and ankle fracture clinic during a 12-month period at our institution under the care of 1 consultant. Data were collected regarding patient demographics, fracture type, patient outcome, and the number of clinic appointments attended, cancelled, or not attended. A total of 707 new patients (mean age 39 ± 19 years; 345 males, 362 females) were seen in 47 foot and ankle fracture clinics within the study period. Seventy-four phalangeal fractures were identified in 65 patients. A total of 135 outpatient appointments were scheduled for these patients (initial and follow-up), with 93 (69%) attended, 25 (19%) not attended, and 15 (11%) cancelled and rescheduled at the patient's request. Seventeen patients (13%) failed to attend their first clinic appointment. The results of the present study highlight that 9% of all new patient referrals to a fracture clinic were for toe phalangeal fractures. Only 2 patients required surgery for significant loss of articular congruency or deformity. No patient subsequently developed a symptomatic malunion or required toe surgery during the following 2 years. We believe that undisplaced and stable toe phalangeal fractures do not need to be referred to the fracture clinic. This would result in a reduction of outpatient appointments for toe fractures by 52%.

Demographics and functional outcome of toe fractures

Toe fractures are common; however, there are few data on demographics and functional outcome. We studied outcomes in 339 consecutive patients with toe fractures treated between January 2006 and September 2008. Two hundred and sixty-four patients, aged 16 to 75, were mailed an outcome questionnaire, and overall subjective satisfaction with the outcome of treatment was measured using a visual analog scale (VAS). Most frequently affected were the first (38%) and fifth (30%) toes, and most (75.6%) of the fractures were caused by stubbing or crush injury. More than 95% of the fractures were displaced less than 2 mm, and all of the fractures were treated conservatively. The questionnaire was returned by 141 (53%) patients with a median follow-up of 27 months. Respondents were female in 57.4% of cases and had a median age of 45 years. The median AOFAS score was 100 (P(25), P(75) = 93,100) points; the median VAS was 10 (P(25), P(75) = 8, 10) points. Univariate regression analysis revealed no statistically significant associations between outcome and the particular toe or phalanx involved, number of fractured toes, fracture type and location, articular involvement, gender, age, body mass index, smoking habits, and the presence of diabetes mellitus. Satisfaction VAS was dependent on age (P = .047) and gender (P = .049) in the multivariate analysis. The AOFAS midfoot score was not influenced by any of the covariates. This is the first epidemiological investigation using 2 outcome-scoring systems to determine function and satisfaction following treatment of toe fractures.
