RESUMEN
Tibiotalocalcaneal arthrodesis (TTCA) is a salvage procedure. We report a series of 20 patients who underwent TTCA using an intramedullary nail. Of the 20 patients, 7 (35%) had diabetes mellitus. The patient experiences and outcomes were analyzed. Their mean age was 61.1 (range 39 to 78) years. The minimum follow-up period was 13 (mean 28, range 13 to 49) months. Surgical indications included diabetic Charcot arthropathy in 7 (35%), hindfoot osteoarthritis in 10 (50%), and severe equinovarus deformity in 3 (15%). A calcaneal spiral blade was used in 2 patients (10%). Significant improvements (p < .05) were observed in 5 of 8 Short-Form 36-item Health Survey components, the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale (p < .001), and visual analog scale for pain (p < .001). The mean length of the hospital stay was 6.7 (range 1 to 27) days. Of the 20 patients, 76.9% had improvement in their activity postoperatively. Also, 81.8% were able to resume their preoperative work after a mean of 7.89 (range 3 to 24) months. Overall, 19 patients (95%) reported favorable outcomes. Superficial wound infection (n = 4; 20%) and deep wound infection (n = 3; 15%) were the most common complications (35%), with 1 case (5%) culminating in a below-the-knee amputation. Radiographic union was achieved in 16 of the tibiotalar joints (80%), 16 subtalar joints (80%), and 4 tibiocalcaneal fusions (20%). In a subgroup analysis of 7 patients with diabetes mellitus (35%), the incidence of wound complications and fusion was comparable to that of the primary cohort. TTCA performed with an intramedullary nail appears to offer a reliable and safe alternative for patients with severe ankle and hindfoot pathologic entities, including those with diabetes mellitus.

CASE: There has been an emerging trend of Klebsiella pneumoniae necrotizing fasciitis (KP-NF). We report a 50-year-old Chinese woman with rapidly progressive KP-NF, presenting atypically with innocuous skin symptoms. She had newly diagnosed diabetes mellitus. She had extensive subcutaneous crepitus in her lower limbs with subcutaneous gas on x-rays. Despite aggressive surgical debridement, she succumbed to septic shock and multiorgan failure. CONCLUSION: KP-NF is an emerging clinical entity and is associated with a compromised host immunity and high mortality rates. Clinicians must be aware that not all may present with the typical fulminant features and should maintain a high index of suspicion.

Patients undergoing prolonged surgery in a lithotomy position may develop acute lower limb compartment syndrome in the absence of trauma or pre-existing vascular disease, otherwise known as well-leg compartment syndrome (WLCS). Early recognition and management would prevent the potential, lethal complications associated with this condition. We present a case of a 55-year-old gentleman who developed bilateral WLCS after prolonged abdominoperineal resection of his pelvic liposarcoma.
RESUMEN
Background Mid-pole patellar fractures are typically fixed with metal implants in the conventional "11-8" tension band construct. However, this technique is fraught with numerous implant-related complications. The aim of this study is to evaluate the union rate following "all-suture" fixation of mid-pole patellar fractures. Methods We retrospectively evaluated a consecutive case series of patients with displaced mid-pole patella fractures treated with "all-suture" fixation in our institution. Fifteen cases were available for this study. The average age was 61.5 years. Clinical and radiological outcomes were evaluated. Union time, complications, and revision rate were recorded. The minimum follow-up was one year. Results There were eight males and seven females, with a mean age of 61.5 ± 13.3 years. Fourteen out of 15 cases (93.3%) achieved radiographic union at 12 weeks postoperatively. The average time to radiographic union was 8.0 ± 2.7 weeks. Five cases (33.3%) had an increase in the fracture gap (>2 mm) at around four to six weeks postoperatively. Four of these cases had an eventual union, whereas one patient had fibrous non-union. There was one case of superficial surgical site infection and one case of infected hematoma. None of the patients required revision surgery. Conclusion "All-suture" fixation of mid-pole transverse patellar fractures is a safe and viable alternative to the conventional "11-8" tension band constructs with metal implants, with good union time, rates, and added benefits of not requiring additional surgery for implant removal.
RESUMEN
BACKGROUND: We consistently observed the presence of anechoic spaces on standard ultrasonographic imaging of the carpal tunnel inlet in normal subjects. These spaces change in size during finger flexion and have not been characterized in a large sample of normal individuals. Ultrasonographic quantification of these spaces may indicate the available space in the region of the carpal tunnel, which allows the normal motion of tendons and the median nerve. METHODS: Transverse ultrasonographic images of the carpal tunnel inlet from 33 asymptomatic volunteers were obtained at Position A (fingers in extension) and B (fingers in flexion). Cross-sectional area (CSA), perimeter and position of anechoic space relative to median nerve were recorded. RESULTS: Analysis showed a 75.4% prevalence rate of a single anechoic space. Two discrete patterns were observed. 89.1% had a decrease in CSA and perimeter of anechoic space from Position A to B while 10.9% exhibited an increase. Mean position of the anechoic space is ulnar (7.49 ± 3.57 mm) and dorsal (2.18 ± 1.28 mm) to the median nerve. CONCLUSIONS: A consistent anechoic space at the carpal tunnel inlet is seen in 75.4% of normal hands and can be quantified (cross sectional area 11.75 ± 7.36 mm(2)). It allows for the accommodation of flexor tendons during finger flexion.

AIM: To prospectively investigate the time taken and patients' ability to resume preoperative level of physical activity after gastrocnemius recession. METHODS: Endoscopic gastrocnemius recession (EGR) was performed on 48 feet in 46 consecutive sportspersons, with a minimum follow-up of 24 mo. The Halasi Ankle Activity Score was used to quantify the level of physical activity. Time taken to return to work and physical activity was recorded. Functional outcomes were evaluated using the short form 36 (SF-36), American Orthopedic Foot and Ankle Society (AOFAS) Hindfoot score and modified Olerud and Molander (O and M) scores respectively. Patient's satisfaction and pain experienced were assessed using a modified Likert scale and visual analogue scales. P-value < 0.05 was considered statistically significant. RESULTS: Ninety-one percent (n = 42) of all patients returned to their preoperative level of physical activity after EGR. The mean time for return to physical activity was 7.5 (2-24) mo. Ninety-eight percent (n = 45) of all patients were able to return to their preoperative employment status, with a mean time of 3.6 (1-12) mo. Ninety-six percent (n = 23) of all patients with an activity score > 2 were able to resume their preoperative level of physical activity in mean time of 8.8 mo, as compared to 86% (n = 19) of patients whose activity score was ≤ 2, with mean time of 6.1 mo. Significant improvements were noted in SF-36, AOFAS hindfoot and modified O and M scores. Ninety percent of all patients rated good or very good outcomes on the Likert scale. CONCLUSION: The majority of patients were able to return to their pre-operative level of sporting activity after EGR.
