Minimally invasive endoscopic management of tubercular tenosynovitis of the anterior tibial tendon.

The incidence of tubercular tenosynovitis around the foot and ankle is rare even in endemic areas. We present an unusual case involving the isolated tubercular tenosynovitis of the Anterior Tibial tendon, which was successfully managed through a combination of medical treatment and endoscopic intervention. Our patient, a 30-year-old female, sought medical attention due to a gradually worsening painful swelling localized to the anterior aspect of her left ankle. Diagnostic imaging, specifically Magnetic Resonance Imaging (MRI), revealed alterations in signal intensity within the Anterior Tibial tendon. Importantly, the infection had not spread to involve the ankle joint. We performed both diagnostic and therapeutic tenosynovectomy endoscopically and subsequently sent the tissue for histopathological examination. The histopathological findings revealed the presence of histiocytic granulomas containing Langhans' giant cells, which strongly suggested a tuberculosis infection. Consequently, we initiated anti-tubercular chemotherapy as the treatment approach. Our patient exhibited a positive response to the treatment, and after one year, she experienced complete resolution of the disease. This case underscores the importance of maintaining a high level of clinical suspicion for tuberculosis, especially in endemic areas, when encountering unusual presentations. Level of evidence: V.

Inter- and Intra-observer Reliability of a New Classification System for Calcaneus Fracture Malunions: The ADEINS Classification.

Background: Currently, two classification systems, namely Stephens and Sanders, based on axial CT images, and Zwipp and Rammelt, which consider deformities, are used for calcaneus malunions. Existing classifications have limitations due to their pure anatomical basis, and the complexity of the problem, involving both bone and soft tissues. As a solution, the senior author proposed a novel ADIENS classification system for calcaneal malunion, based on pain generators. This study aimed to introduce and evaluate the inter- and intra-observer reliability of a new classification system for calcaneal malunions. Methods: This retrospective cohort study included adult cases with post-traumatic calcaneus malunion. Three experienced foot and ankle surgeon volunteers underwent training session on the classification system, which classifies malunions based on A arthritis, D deformity, E exostosis, I implant issues, N nerve issues, and S soft tissue issues. Post-training, two rounds of classification exercises were conducted. Inter-rater and intra-rater agreements were determined using Gwet's AC coefficient. Results: Out of 15 cases, 6 were of Stephen and Sanders types, and 8 were of Zwipp and Rammelt types, the rest fell out of these classifications. Inter-rater agreement for ADEINS classification was noted to be 'very good' for all six domains. Intra-observer agreements were 'very good' for four out of six domains of classification and 'fair' for two domains of classification. Conclusion: Pain generators-based new ADEINS classification has demonstrated good intra- and inter-observer reliability and seemed user-friendly. However, results need to be replicated in a larger, multicentric cohort before wider clinical applicability. Level of Evidence: Level IV, retrospective study.

Demystifying Giant Cell Tumours of Tendon Sheath (GCTTS): A Case Series of 18 Cases with Review of Literature.

Background: The giant cell tumour of the tendon sheath (GCTTS) is the second most frequent soft tissue tumour affecting the hand. No consensus exists on the etiology, prognostic factors, or recurrence rate of GCTTS. This article presents a series of 18 cases supplemented by a literature review that examines the epidemiology, presentation, gross and microscopic characteristics, and recurrence rate of GCTTS. Methods: A total of 18 patients with a histo-pathological diagnosis of a GCTTS of the hand or finger were reviewed. The location for the tumour was limited to the wrist and hand. All cases were operated under Wide Awake Local anaesthesia (WALANT), and using a magnifying loupe. Results: A total of 18 patients presented at our institution with a diagnosis of GCTTS from 2016 to 2018. Of the 18 patients, 11 were female and 7 were male. The mean age of included patients was 43.6 years (31-59 years). The most common site for the lesion was the middle finger (4/18), followed by the index finger, wrist, and thumb (3/18 each). The little and ring finger were least commonly affected with one case each. The mean size of the tumour was 2.4 cm (0.5-5 cm). None of the patients reported recurrence of the lesion on an average follow-up of 18.8 months. Conclusion: GCTTS is a benign, slowly growing lesion of the hand that typically does not cause any symptoms and is treated with surgical resection. Meticulous excision of the GCTTS using magnification loupes to ensure appropriate wide excision of the tumour is the treatment of choice to prevent a recurrence. In addition, a radiographic and histopathological examination must be performed on the tumour to rule out other diagnoses. Finally, the function of the hand should be reconstructed to minimize the loss of any functional unit.

Patient and Surgical Factors Affecting Fusion Rates After Arthroscopic and Open Ankle Fusion: A Review of a High-Risk Cohort.

Abstract: We present a case series with the objective of identifying risk factors for nonunion after open and arthroscopic primary ankle arthrodesis. Eighty-seven patients who underwent primary ankle arthrodesis and met inclusion criteria were divided into open (N = 46) and arthroscopic (N = 41) groups. Patient and operative characteristics were retrospectively analyzed as possible risk factors for nonunion within each technique. The nonunion rate was 11% in the open and 12% in the arthroscopic group. Obesity, smoking, and ASA class 3 were highly prevalent in both groups. In the arthroscopic group, a remote history of infection and the use of headed screws had notably higher risk of nonunion, though not statistically significant. In the open group, use of bone graft trended toward lower risk of nonunion, though also not statistically significant. The results of this study demonstrated, nonunion rates are comparable between open and arthroscopic ankle arthrodesis in high-risk patients. For patients with a remote history of infection, open ankle arthrodesis may be preferable, and bone graft importance may vary with open versus arthroscopic technique. Level of evidence: III.

Pulley Reconstruction Following Surgical Release of DC1 Pulley in De Quervain's Tenosynovitis: Surgical Technique and Case Series.

De Quervain's disease (DQD) is tenosynovitis of the first dorsal compartment (DC1) of the wrist between the osteofibrous tunnel and the tendons involving the APL and EPB sheaths at the radial styloid. Surgical intervention is indicated when pain does not resolve despite 3 to 6 months of conservative management. Release of the first dorsal compartment is an effective treatment of DQD. In addition to surgical release, we performed pulley reconstruction using a new technique in the present series of 20 patients which has not been previously described with a followup of over 1 year. All patients showed a consistent improvement in VAS score at over one year followup with resolution of Finkelstein, Eichoff and WHAT test. Only one temporary neuropraxia was encountered due to stretching/scar entrapment of superficial branch of radial nerve. Our innovative technique of pulley reconstruction is not only easy to understand and perform but has shown consistent result in the 20 cases operated with this technique with a follow up of at least 1 year. The technique has the distinct advantage of having a quick learning curve and gives reliable, lasting results without complications or recurrence.

A Potentially Dangerous Industrial Projectile Lodged in the Leg of a Steel Factory Worker.

Penetrating injuries due to fragments energized by an explosive event are life/limb-threatening and are associated with poor clinical and functional outcomes. Penetrating injuries are commonly inflicted in attacks with explosive devices. The extremities, especially the leg, are the most commonly affected body areas, presenting a high risk of infection, slow recovery, and the threat of amputation. This report presents a case of a young factory worker who sustained an injury to the leg with a foreign body lodged near the neuro-vascular bundle. A 44-year-old gentleman sustained a projectile injury while working in a stainless steel factory from the rula (steel rolling) machine with a foreign body getting lodged in the leg in March 2019. He was initially managed with wound care and didn't report any functional impairment. Gradually patient developed numbness and claudication symptoms of the foot over the next couple of years. He was subsequently operated on in 2021 for removal of the stainless steel foreign body encased in dystrophic calcification close to the tibial nerve and posterior tibial vessels. Interestingly the entry point of the foreign body was on the anterolateral aspect of the leg. The foreign body was removed using the postero-lateral approach to the tibia with careful dissection close to the neurovascular bundle. At a follow-up of 3 months, the patient is symptom-free with significant improvement of limb function. The authors propose that the foreign body crossed the interosseous membrane to get lodged close to the posterior tibial neurovascular bundle. In such a scenario, the patient was extremely lucky to have survived an amputation or significant functional injury of the limb. Proper protective equipment is needed not only for the torso but also for extremities to protect industrial workers from such limb-threatening injuries. Moreover, primary care physicians should be sensitised for the proper management of such injuries.

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.

Minimally invasive vs open distal metatarsal osteotomy for hallux valgus - A systematic review and meta-analysis.

BACKGROUND: Numerous publications of the late 20th century have presented the radiological outcome of open technique for distal metatarsal osteotomy for mild to moderate hallux valgus and the clinical outcomes by means of well-established scoring systems which have been published and make these open techniques today's benchmark and gold standard. Minimally invasive procedures reduce surgical trauma because they are performed without large incisions, and injury to the soft tissues is limited. This has the theoretical advantages of improved recovery and decreased rehabilitation times. There is however limited literature to prove the same for minimally invasive surgery for hallux valgus.Our aim was thus to pool all available comparative literature on minimally invasive hallux valgus surgery done for mild to moderate hallux valgus versus open surgical approaches. METHODS: A PubMed, Embase and Scopus search was performed using the keywords ('hallux valgus' OR bunion) AND ('minimally invasive' OR percutaneous) AND osteotomy. A total of 473 records were identified and out of which nine studies were included in the final review. RESULTS: Most available studies are either randomized control trials, or prospective cohort studies providing good level of evidence. Radiological analysis showed similar correction with both MIS and open osteotomies. In functional analysis results were different with open techniques providing better results in terms of AOFAS score. (p < 0.0001). VAS score and complication rate were similar in both groups. DISCUSSION/CONCLUSION: We conclude that based on available literature MIS provides equivalent radiological outcomes with respect to open surgery but functionally despite the promising results (good to excellent in most series), the outcomes in terms of function are not as good as open surgery. MIS techniques provide satisfactory outcomes for mild-to-moderate severity of hallux valgus though not as good as open surgery. There is evolving literature for this relatively new procedure. Longer duration of follow up and bigger numbers would allow for more meaningful data analysis and conclusions to be drawn as more studies come forward.

The "Open-Envelope" Approach: A Limited Open Approach for Calcaneal Fracture Fixation.

BACKGROUND: Minimally invasive surgery (MIS) has a significant and evolving role in the treatment of displaced intra articular calcaneal fractures (DIACFs), but there is limited literature on this subject. The objective was hence to assess the clinicoradiological outcomes of DIACFs fixed with an innovative open-envelope MIS technique. MATERIALS AND METHODS: 42 closed Sanders Type 2 and 3; DIACFs were included in this study. The Open-envelope approach was developed, which is essentially a limited open, dual incision, modified posterior longitudinal approach allowing excellent visualisation and direct fragment manipulation. The main outcome measures were American Orthopaedic Foot and Ankle Score (AOFAS) hindfoot score and preoperative and postoperative radiological angles. RESULTS: The Bohler angle improved from a preoperative mean of 14.3° (range 0°-28°) to a postoperative mean of 32.46° (range 22°-42°). The Gissane angle improved from a preoperative mean of 135.83° to a postoperative mean of 128.33°. The postoperative improvement in Bohler and Gissane angles was highly significant (P < 0.001). The AOFAS scores at 6 months were excellent in nine patients, good in 15 patients, and fair in six patients. Three patients had residual valgus deformity of the heel. CONCLUSIONS: Open-envelope technique minimized soft tissue complications and achieved acceptable radiological reductions with good clinical outcomes.

Outcome evaluation of minimally invasive surgery versus extensile lateral approach in management of displaced intra-articular calcaneal fractures: A randomised control trial.

BACKGROUND: Minimally invasive surgery has a significant and evolving role in the treatment of DIACFs, but there is limited literature on this topic. OBJECTIVES: To compare the clinico-radiological outcomes of DIACFs fixed with MIS technique with ORIF. METHODS: This randomised control trial (RCT) included 21 closed Sanders type 2 and 3 DIACFs which were selected from 70 who presented. Extensile lateral approach was used in the ORIF group; while MIS techniques included either percutaneous reduction or small incisions with indirect fragment manipulation. MAIN OUTCOME MEASUREMENT: AOFAS hindfoot score, pre-operative and postoperative radiology. RESULTS: There were 9 fractures in the Extensile group and 12 in the MIS group, with both groups having comparable demography, fracture classification, surgery delay & initial radiology. Bohler's angle improved after surgery by an average of 18.44 with ORIF and 14.67 with MIS (p=0.28). Mean AOFAS in the MIS group was 82.58 (66.67% good and 33.33% fair) and was 89.56 (44.44% excellent, 55.56% good, 0 fair/poor) with ORIF (p=0.034). Two patients who underwent ORIF had a major complication (one deep infection and Sural nerve injury each) while none in the MIS group. CONCLUSIONS: MIS methods minimized soft tissue complications and achieved comparable radiological reductions but clinical outcomes were poorer, with percutaneous methods having the worst outcomes.
