Surgical management of spiral oblique fractures of the fifth metatarsal leads to faster return to play in athletes: A systematic review.

PURPOSE: The purpose of this systematic review was to evaluate outcomes following both operative and nonoperative management of spiral oblique fractures of the fifth metatarsal. METHODS: During November 2023, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following operative and nonoperative management of dancer's fractures. Data regarding subjective clinical outcomes, radiological outcomes, complications and failure rates were extracted and analysed. RESULTS: Ten studies were included in this review. In total, 125 patients underwent operative treatment for dancer's fractures and 365 patients underwent nonoperative treatment for dancer's fractures. The weighted mean follow-up in the operative cohort was 15.3 ± 32.7 months and the weighted mean follow-up in the nonoperative cohort was 30.6 ± 24.3 months. The overall union rate in the operative cohort was 99.2% and the overall union rate in the nonoperative cohort was 98.6%. The weighted mean time to return to sport was 15.4 ± 6.7 and 22.4 ± 4.4 weeks in the operative cohort and nonoperative cohort, respectively. The complication rate in the operative cohort and nonoperative cohort was 12.0% and 15.1%, respectively. CONCLUSION: This current systematic review demonstrated comparable radiographic outcomes together with low failure rate and low complication rate following both operative and nonoperative management of dancer's fracture at short-term follow-up. However, faster return to sport rates was observed in the operative cohort, suggesting that surgical management of displaced spiral oblique fractures of the fifth metatarsal should be the mainstay treatment option. However, the under-reporting of data, marked heterogeneity between studies and paucity of comparative studies limits the generation of any robust conclusions; thus, further high-quality comparative studies are warranted. LEVEL OF EVIDENCE: Level IV.

Limited evidence of adjuvant biologics with bone marrow stimulation for the treatment of osteochondral lesion of the talus: a systematic review.

PURPOSE: To evaluate the complication rates, continuous functional outcome scores, and return to play data following bone marrow stimulation (BMS) versus biologics ± BMS for the treatment of osteochondral lesion of the talus (OLT). METHODS: A systematic review was performed. The PubMed and Embase databases were searched using specific search terms and eligibility criteria according to the PRISMA guidelines. The level of evidence was assessed using published criteria by The Journal of Bone & Joint Surgery, and the quality of evidence using the Modified Coleman Methodology Score. Continuous variables were presented as mean ± standard deviation and categorical variables as frequencies (percentages). RESULTS: BMS versus BMS + hyaluronic acid (HA): no complications in either treatment arm were reported. The mean American Orthopaedic Foot and Ankle Society score was 43.5 to 67.3 points and 44.0 to 72.4 points, respectively. The mean 10 mm Visual Analogue Scale pain score was 7.7 to 3.8 points and 7.5 to 2.5 points, respectively. BMS versus BMS + concentrated bone marrow aspirate (CBMA): the pooled overall complication rate was 17/64 (26.6%) versus 11/71 (15.5%), respectively (non-significant). The pool revision rate was 15/64 (23.4%) versus 6/71 (8.5%), respectively (p = 0.016). There has been a notable poor reporting of complication rates for the use of ADSC and PRP as adjuvant biological therapies to BMS for the treatment of OLT. CONCLUSION: There was an overall limited comparative clinical evidence of adjuvant biologics with BMS versus BMS alone for the treatment of OLT. BMS + HA and BMS + CBMA can provide superior outcomes, albeit the currently limited evidence. Further studies are warranted to establish the true clinical superiority of the various biologics ± BMS versus BMS alone. These studies must also compare the various biologics against one another to determine, if any, the optimal biologic for OLT. Clinicians should counsel patients accordingly on these findings as required. LEVEL OF EVIDENCE: Level III.

Anatomy of the tibial nerve in relation to the tarsal tunnel: A cadaveric study.

BACKGROUND: Tarsal tunnel syndrome (TTS) is typically caused by an anatomical variant or mechanical compression of the tibial nerve (TN) with variable success after surgical treatment. METHOD: 40 lower-leg specimens were obtained. Dissections were appropriately conducted. Extremities were prepared under formaldehyde solution. The tibial nerve and branches were dissected for measurements and various characteristics. RESULTS: The flexor retinaculum had a denser consistency in 22.5% of the cases and the average length was 51.9 mm. The flexor retinaculum as an independent structure was absent and 77.2% of cases as an undistinguished extension of the crural fascia. The lateral plantar nerve (LPN) and abductor digiti minimi (ADM) nerve shared same origin in 80% of cases, 34.5% bifurcated proximal to the DM (Dellon-McKinnon malleolar-calcaneal line) line 31.2% distally and 34.3% at the same level. CONCLUSION: Understanding the tibial nerve anatomy will allow us to adapt our surgical technique to improve the treatment of this recurrent pathology.

Intra-Tendinous Ganglion Cyst of the Peroneus Tertius: A Case Report and Literature Review.

BACKGROUND This article presents a rare case of an intra-tendinous ganglion cyst of the peroneus tertius. Ganglion cysts are benign lesions frequently seen in hand pathologies, but they are rarely seen in the foot and ankle. This article discusses the present case and similar previously reported cases in the English literature. CASE REPORT We present a case of a 58-year-old man with a 3-year history of right foot pain caused by a mass located at the dorso-lateral aspect of the midfoot. Preoperative MRI demonstrated a ganglion cyst arising from the peroneus tertius tendon sheath. The lesion was successfully decompressed in the office; however, it recurred 7 months later. As it was symptomatic, we elected to proceed with surgical resection. During dissection, it became apparent that the cyst was arising from an intrasubstance tear of the peroneus tertius tendon, and a branch of the superficial peroneal nerve was noted to be adherent to the pseudo-capsule. Following excision of the lesion and its expansile pseudo-capsule, the tear was repaired with tubularization of the tendon and external neurolysis of the nerve was performed. At 6 months after surgery, there was no recurrence of the lesion, and the patient was pain free and had regained normal physical function. CONCLUSIONS Intra-tendinous ganglion cysts are rare, especially in the foot and ankle. This makes it challenging for an accurate preoperative diagnosis. When a tendon is arising from a tendon sheath, we recommend exploration of the underlying tendon for an associated tear.

Surgical Management of Chronic Achilles Tendon Ruptures: A Systematic Review and Proposed Treatment Algorithm.

Background: As no evidence-based treatment guidelines exist for chronic Achilles tendon rupture (CATR), a systematic review of the literature was performed to compare the different treatment options and recommend a literature-based algorithm. Methods: In June 2022, MEDLINE, Embase, and Cochrane Library databases were systematically reviewed based on the PRISMA guidelines. The level of evidence (LOE) and quality of evidence were evaluated, and statistics on clinical outcomes and complications were calculated. Results: Twenty-seven studies with 614 patients were included. Three studies were LOE III and 25 studies were LOE IV. The mean Achilles tendon rupture score improved from a preoperative weighted mean of 38.8 ± 12.4 to a postoperative score 90.6 ± 4.7. The overall complication rate was 11.4%. Single techniques were used in 23 studies and dual techniques were used in 5 studies. The FHL tendon transfer was the most frequently used technique. We devised an algorithmic approach based on time from injury to surgical intervention and the length of the gap between the tendon stumps: >3 months: FHL transfer; <3 months (a) gap <2 cm, end-to-end repair; (b) gap 2 to 5 cm, gastrocnemius transfer, (c) gap >5 cm, semitendinosus autograft. Conclusion: Surgical management of CATR produced improvements in patient-reported outcome scores at midterm follow up, but a high complication rate (11.4%) was noted. Our proposed treatment algorithm may assist in shared decision making for this complex problem.

Implications of obesity in patients with foot and ankle pathology.

Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2. It is predicted that by 2030, 48.9% of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups. This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields. The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies, with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates. In line with increasing interest on the impact of obesity in orthopedics, there has been a similar output of publications in the foot and ankle literature. This review article evaluates several foot and ankle pathologies, their risk factors associated with obesity and subsequent management. It provides an updated, comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes, with the ultimate aim of educating both surgeons and allied health professionals about the risks, benefits, and modifiable factors of operating on obese patients.

Calcaneal reconstruction using a femoral head allograft and biologic adjuncts: A case report.

We present a case of calcaneal reconstruction after both an improvised explosive device injury and subsequent salvage procedures left the patient with a large calcaneal defect and damaged hindfoot soft tissue. A subtalar arthrodesis was performed with a femoral head allograft, where it was fused to the remaining calcaneus and superiorly through the talus, to successfully reconstruct this defect. Demineralized bone matrix, bone morphogenetic protein, and concentrated bone marrow aspirate were also added as adjuncts to promote bone remodeling. At final follow-up, the patient denied pain, was fully weight-bearing, and had resumed an active lifestyle. Level of Evidence: Level V, Case Report.
