Antibiotic Treatment for Pyogenic Flexor Tenosynovitis Following Animal Bites.

BACKGROUND: Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics. OBJECTIVES: To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora. METHODS: We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology. RESULTS: Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855). CONCLUSIONS: Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.

Ulnar Superficialis Slip Resection Versus Radial Superficialis Slip Resection: A Biomechanical Pilot Study.

BACKGROUND: There are numerous clinical scenarios during which the surgeon contemplates whether the radial or ulnar slip of the flexor digitorum superficialis (FDS) should be sacrificed. To date no study has assessed the point of failure of each one of the FDS slips in each digit, aiding the avid surgeon in deciding which slip to sacrifice. METHODS: A total of 41 digits were assessed, each digit was dissected, and a specimen containing the denuded bone of the middle phalanx with the attachments of the ulnar and radial FDS slips was obtained. An Instron 4502 device was utilized to biomechanically assess the point of failure of each slip of each digit. RESULTS: There was no statistical difference between ulnar and radial slip point of failure when compared across all digits and subjects. There was no statistical difference between male and female subject's specimens. The point of failure was higher in the ulnar slips of the second and third digits, whereas the point of failure was higher in the radial slips of the fourth and fifth digits. CONCLUSIONS: Sacrifice of a FDS slip may cause loss of grip strength. In several clinical scenarios one may be faced with the dilemma which FDS slip to sacrifice. Our findings show this is not an arbitrary choice. Hand surgeons should keep our findings in mind when deciding which slip to sacrifice, in effort to preserve function and strength in the injured hand.

The influence of early virtual reality intervention on pain, anxiety, and function following primary total knee arthroplasty.

BACKGROUND: Total knee arthroplasty (TKA) is one of the most popular surgeries in the orthopedic field. One of the reasons for a failed TKA is pain and difficulty to return to normal function. A pain control method that is becoming more and more popular is the use of virtual reality (VR). We aimed to examine VR intervention in the immediate post-operative physiotherapy following TKA. METHODS: This prospective randomized-controlled study recruited a total of 55 patients undergoing primary TKA in a single institute, operated by three surgeons. They were assigned either study group or control group. Both groups were treated with conventional physiotherapy and CPM equipment (Continuous passive motion device), the study group received additional VR modality. Both groups completed a series of questionnaires prior and after the intervention: State-Trait Anxiety Inventory (STAI) questionnaire (used to diagnose anxiety), Visual analog scale (VAS) for pain and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) (knee function score). RESULTS: The average age was 70 years-old with equal distribution of male and female. Both groups showed a decrease in pain and anxiety following the intervention (p value < 0.05) but there was no difference between the groups (p value > 0.05 for all parameters). The was no difference in the WOMAC scores in the six-month post-operative examination between groups (p-value = 0.653). CONCLUSIONS: Virtual reality intervention in the immediate post-operative period following total knee arthroplasty decrease pain and anxiety but did not influence the pain, anxiety, and long-term function results more than conventional physiotherapy.

Proximal humeral nail for treatment of 3- and 4-part proximal humerus fractures in the elderly population: effective and safe in experienced hands.

BACKGROUND: Optimal treatment of 3- and 4-part proximal humerus fractures (PHFs) remains controversial. Although commonly recommended for less comminuted PHFs, the outcomes of treatment with proximal humerus nailing (PHN) are more equivocal. The purpose of this study was to report on radiographic and clinical outcomes of patients undergoing PHN fixation of 3- and 4-part PHFs at minimum one-year follow-up. Our hypothesis was that the findings would demonstrate satisfactory radiographic and clinical outcomes, with low rates of complications and revision surgeries. METHODS: Between 2008 and 2016, 121 patients with comminuted, low-energy, osteoporotic, PHFs underwent fixation via Targon PHN (Aesculap, Tuttlingen, Germany). Of these, 60 patients met inclusion and exclusion criteria and were included in this analysis (mean age 72; range 65-85). All completed a minimum 1-year follow-up (range 12.5-82 months). Patients with 3-part PHFs were compared to patients with 4-part PHFs. Clinical, radiographic, and functional outcomes were assessed at postoperative visits. Patient reported outcomes included pain, the American Shoulder and Elbow Surgeons (ASES) score and the Simple Shoulder Test (SST). Radiographic union and revision and complication rates were assessed. RESULTS: Overall, 37 (62%) fractures were classified as Neer 3 and 23 (38%) were classified as Neer 4. Both groups achieved similar postoperative range of motion. Patients with 3-part fractures reported significantly lower postoperative pain (0.76 ± 1.8 vs. 1.65 ± 2.2, p = 0.0047). Patients with 3-part fractures reported significantly better ASES scores (82.4 ± 19.2 vs. 70.8 ± 21.9, p = 0.02) and non-statistically significant higher SST scores (8.4 ± 3.2 vs. 7.43 ± 3.8, p = 0.14). Adequate fracture union was achieved in 53 fractures (88.3%). Three patients (5%) had varus malunion or greater tuberosity displacement, one (1.7%) had mechanical failure, and three (5%) had radiographic evidence of avascular necrosis. Between groups, there was no difference in failure rates. CONCLUSION: Proximal humeral nails can successfully be used by experienced surgeons in fixation of comminuted and displaced proximal humeral fractures in selected patients with osteoporosis. While patients with both 3- and 4-part fractures demonstrate fracture union with satisfactory outcomes, patients with 3-part fractures demonstrate significantly higher postoperative functional scores.

Selective Component Retainment in the Treatment of Chronic Periprosthetic Infection After Total Hip Arthroplasty: A Systematic Review.

INTRODUCTION: Chronic infections after a total hip arthroplasty (THA) are a devastating complication and are usually treated by a complete revision of components. Selective revision, with preservation of well-fixed components, has been previously reported. We did a systematic review to report on success rates of selective revision in chronic infections after THA. METHODS: PubMed, Web of Science, and the Cochrane Database were systematically searched for studies reporting on partial-retaining revision for chronically infected THA. These were reviewed to determine success rates based on component revised, as well as infectious organism. RESULTS: Nine studies reported on 134 patients. The majority of the patients underwent femoral-retaining procedures (118), and the rest of the patients underwent acetabular-retaining procedures (16). Average follow-up was 60.56 months, and the success rates were 80% for femoral revision, 90.43% for acetabular revision, and overall success rate was 89.41%. DISCUSSION: In select patients, retainment of well-fixed components in chronically infected THA may be considered. Although reported success rates are high, and comparable with complete revision arthroplasty in cases of chronic infections, the quality of the studies included is poor. The studies lacked sufficient internal validity, sample size, methodological consistency, and standardization of protocols and outcomes. LEVEL OF EVIDENCE: Systematic review of level IV studies.

[BISPHOSPHONATES AS A PREVENTATIVE TREATMENT FOR OSTEOPOROTIC HIP FRACTURES: A MIXED BLESSING].

BACKGROUND: The widespread use of bisphosphonates for treating osteoporosis in the last two decades has raised concern about the complication of atypical hip fractures secondary to bisphosphonate treatment. These fractures may be the result of a minor trauma to the hip or without any trauma at all. It may be heralded by prodromal groin or hip pain. Prolonged bisphosphonate treatment and atypical fractures may exist, but the nature and the extent of this linkage are still unknown. Currently, there is a lack of adequate evidence-based methods or a consensus about the treatment of this unique phenomenon. METHODS: We retrospectively examined the records of all subtrochanteric hip fracture cases admitted to our department in the years 2010-2014. During that period, we treated a total of 1315 patients:726 patients with pertrochanteric fractures, 514 patients with subcapital fractures and 75 patients with distal subtrochanteric fractures. Among those, 16 patients (1.2%) qualified as atypical hip fractures. The location of the fracture, period of bisphosphonates use, fixation type, complications and recovery were recorded. RESULTS: The average age of the patients in our study was 76.9 years. All patients were treated with bisphosphonates and over 80% of the patients were treated specifically with Alendronate prior to the fracture. Mean treatment time was 7.8 years. Most of the fractures (75%) were subtrochanteric, and the others were at the femur midshaft. All patients received surgical fixation and all accomplished union of the fractures. CONCLUSIONS: It seems reasonable to assume a causative relationship between a long term use of bisphosphonates and the occurrence of atypical hip fractures. It is a relatively rare complication; nevertheless, it should be kept in mind during a long term use of bisphosphonates. According to our department's clinical experience we found no delay in bone union with these atypical hip fractures. It seems reasonable to prophylactically fixate atypical stress fractures before they become a full fracture.

Does Timing of Arthroscopic Partial Meniscectomy in Stable Knees Matter?

The timing of arthroscopic partial meniscectomy (APM) is not well defined. The purpose of this study was to evaluate the impact of early surgical intervention on the short-term improvement in clinical outcome. Between June 2012 and July 2013, patients who had APM for symptomatic irreparable meniscal tears in stable knees with no preoperative radiographic osteoarthrosis were included (n = 187). The mean age was 45.6 ± 14.5 years. Early surgical intervention (duration of symptoms of less than 3 months) was evaluated together with various preoperative and operative variables in a multivariable stepwise regression analysis, while the improvement in Lysholm knee score was modeled as a function of these predictors. At the last follow-up, the mean Lysholm knee score improved by 14.7 points and 79% of all patients declared they were satisfied to have had the operation; however, of the various predictors in the regression analysis, patients who had shorter duration of symptoms or better clinical function before surgical intervention had greater improvement in clinical score. In conclusion, early APM for symptomatic irreparable tears in stable knees without preoperative arthrosis had better improvement in clinical results than in delayed intervention.

The medial border of the tibial tuberosity as an auxiliary tool for tibial component rotational alignment during total knee arthroplasty (TKA).

PURPOSE: The objective of this study was to quantify the amount of ensuing internal rotation of the tibial component when positioned along the medial border of the tibial tubercle, thus establishing a reproducible intraoperative reference for tibial component rotational alignment during total knee arthroplasty (TKA). METHODS: The angle formed from the tibial geometric centre to the intersection of both lines from the middle of the tibial tuberosity and its medial border was measured in 50 patients. The geometric centre was determined on an axial CT slice at 10 mm below the lateral tibial plateau and transposed to a slice at the level of the most prominent part of the tibial tuberosity. Similar measurements were taken in 25 patients after TKA, in order to simulate the intraoperative appearance of the tibia after making its proximal resection. RESULTS: This angle was found to be similar (n.s.) in normal and post-TKA tibiae [median 20.4° (range 15°-24°) vs. 20.7° (range 16°-25°), respectively]. In 89.3 % of the patients, the angle ranged from 17° to 24°. No statistical difference (p n.s.) was found between women and men in both normal [median -20.7° (range 16°-25°) vs. 19.9° (range 15°-24°)] and post-TKA tibiae [median 21.4° (range 19°-24°) vs. 20° (range 16°-25°)]. CONCLUSION: This study found that in 90 % of the patients, the medial border of the tibial tuberosity is internally rotated 17°-24° in relation to the line connecting the middle of the tuberosity to the tibial geometric centre. Since this anatomical landmark may be more easily identifiable intraoperatively than the commonly used "medial 1/3", it can provide a better quantitative reference point and help surgeons achieve a more accurate tibial implant rotational position. LEVEL OF EVIDENCE: Cohort and case control studies, Level III.

Anamnestic prediction of bucket handle compared to other tear patterns of the medial meniscus in stable knees.

OBJECTIVE: The aim of this study was to analyze and compare the preoperative anamnestic details between patients with an arthroscopic diagnosis of bucket handle and other tear patterns of the medial meniscus in stable knees. METHODS: A total of 204 patients (mean age 49.3 ± 13 years) were included in the study. The mean age was 49.3 ± 13 years. The study group included 65 patients (63 males, 2 females) with an arthroscopic diagnosis of bucket handle tear and the control group included 139 patients (90 males, 49 females) with non-bucket handle tear patterns. The preoperative clinical assessments of the two groups were analyzed retrospectively. Anamnestic prediction for the diagnosis of a bucket handle tear was based upon various medical history parameters. Multivariate logistic regression was carried out to identify independent anamnestic factors for predicting isolated bucket handle tears of the medial meniscus compared to non-bucket handle tears. RESULTS: Analysis of the multivariate logistic regression yielded 3 statistically significant independent anamnestic risk factors for predicting isolated bucket handle tears of the medial meniscus: male gender (OR, 9.7; 95% CI, 1.1-37.6), locking events (OR, 4.6; 95% CI, 1.8-11.3) and pain in extension (OR, 6.9; 95% CI, 2.5-23.7). Other preoperative variables such as age, BMI, activity level, comorbidities, duration of symptoms, pain location, preceding injury and its mechanism had no significant effect on tear pattern. CONCLUSIONS: Preoperative strong clues for bucket handle tears of the medial meniscus in stable knees are male gender, locking events and limitation in extension. LEVEL OF EVIDENCE: Level III, Diagnostic study.

Arthroscopic meniscectomy of traumatic versus atraumatic tears in middle aged patients: is there a difference?

INTRODUCTION: Meniscal tears can be classified in various ways, one of which is into traumatic or degenerative. It is not known whether partial meniscectomy of clinically defined traumatic compared to degenerative tears in middle age patients has favorable results. The purpose of this study was to compare the outcome after arthroscopic partial meniscectomy of clinically defined traumatic to degenerative meniscal tears in middle age patients. MATERIALS AND METHODS: Eighty-six middle aged patients with stable knees and no radiographic signs of osteoarthritis who had arthroscopic partial meniscectomy were divided into a study group of 43 patients with a preceding knee injury related to their knee symptoms (traumatic group) and a control group of 43 uninjured patients (atraumatic group), matched by age, sex, body mass index and comorbidities. The surgical findings and postoperative clinical scores were compared between the two groups. RESULTS: There were no statistical differences in surgical findings of tear types and degree of chondral lesions. At the end of the follow-up 33 (77 %) patients in each group were satisfied to have had the operation. The median Lysholm score improved from 65.9 ± 17.4 to 77.4 ± 21.2 points (P = 0.001) in the traumatic group and from 65.3 ± 17 to 82.4 ± 17.7 in the atraumatic group (P < 0.0001). CONCLUSIONS: Arthroscopic partial meniscectomy in middle aged patients with stable knees and no signs of radiographic osteoarthritis improve pain and function. There were no differences in surgical findings and short term clinical outcome between patients with and without preceding knee injury.

The Use of a Supra-Acetabular Antibiotic-Loaded Cement Shelf to Improve Hip Stability in First-Stage Infected Total Hip Arthroplasty.

BACKGROUND: Antibiotic-loaded cement spacers in first-stage revision total hip arthroplasty (THA) for managing infection are associated with high dislocation and fracture rates. The aim of this study was to report the use of an antibiotic-loaded cemented supra-acetabular roof augmentation to reinforce hip stability after cement spacer insertion for first-stage total hip revision in the treatment of infected THA. METHODS: We retrospectively reviewed a consecutive series of 50 THAs involving 47 patients with an infected hip requiring staged revisions of THA. We documented dislocation, reinfection, and time for revision and outcome. RESULTS: There were no cases of hip dislocation, cement fractures, or any other technical complications associated with the use of the roof augmentation lip. Thirteen cases (26%) had a cemented spacer for longer than 120 days. Seven (14%) cases had recurrent infection after staged revision THA. CONCLUSION: The antibiotic-loaded cemented supra-acetabular roof augment improved femoral head spacer coverage for patients requiring a staged revision THA for infection.

The Sphygmomanometer Pain Test: A Simple Method for Identifying Patients at Risk of Excessive Pain after Total knee Arthroplasty.

BACKGROUND: Despite the overall success of total knee arthroplasty (TKA), a relatively large proportion of patients remain dissatisfied with the outcome. We hypothesized that patients with a lower threshold for pain were more likely to have worse outcomes after TKA. METHODS: Forty-eight consecutive patients with primary knee osteoarthritis graded a standardized painful stimulus caused by inflating a sphygmomanometer placed on the forearm, on a visual analog scale (VAS) scale before their TKA. We compared the VAS scores to patients' Knee Society scores and Knee Society function scores 2 years after TKA. RESULTS: Patients with a severe VAS score (>74 mm) had significantly worse Knee Society scores compared to patients with mild (0-44 mm) and moderate (45-74 mm) VAS scores (55 ± 20.5 vs 81.5 ± 11.1 and 84.8 ± 13, respectively, P = .04) and worse Knee Society Function scores (34 ± 20.7 vs 75.2 ± 17.3 and 77 ± 17.4, respectively, P = .027) at 2 years after TKA. CONCLUSIONS: Patients with a lower threshold for pain, as determined by a standardized painful stimulus, are more likely to have lower Knee Society pain and function scores after TKA.

Which patients are less likely to improve during the first year after arthroscopic partial meniscectomy? A multivariate analysis of 201 patients with prospective follow-up.

PURPOSE: To determine which specific factors influence the improvements in function and pain at the first year following arthroscopic partial meniscectomy. METHODS: Between 2012 and 2013, patients who had arthroscopic partial meniscectomy were included (n = 201) and followed prospectively before surgery and at 12 months. Multivariable stepwise analysis included preoperative variables (age, gender, limb side, height, weight, body mass index, comorbidities, smoking, Tegner activity scale, Lysholm knee score, preceding injury and duration of preoperative symptoms) and arthroscopic findings (degree of cartilage lesions, medial or lateral meniscus involvement, type of meniscal tear and concomitant cruciate tear). The Lysholm clinical score at the last follow-up and the time interval for substantial pain relief was modelled as a function of the above predictor variables. RESULTS: At the last follow-up, the mean Lysholm score improved by 14.6 points (95 % CI 10.4-18.8, P < 0.001), from 68.0 ± 16.1 to 82.6 ± 19.6 points and 153 (76 %) patients declared they were satisfied to have had the operation. The mean time interval for substantial pain relief was 3.5 ± 1.5 months. Females and patients with lower preoperative Lysholm score were correlated with lower post-operative Lysholm score, while females and patients with lateral meniscal tears (compared to medial meniscal tears) were correlated with longer recovery. CONCLUSIONS: Arthroscopic partial meniscectomy improved pain and function at the first year post-operatively. Female gender, lateral meniscal tear and less favourable preoperative function were relatively correlated to worse post-operative function and longer rehabilitation time. LEVEL OF EVIDENCE: IV.

Gender Effect on the Outcome of Partial Medial Meniscectomy.

Complex posterior horn tears of the medial meniscus are common. Previous reports performed statistical stratifications to address the influence of gender on outcome following arthroscopic partial medial meniscectomy with variable conclusions. The aim of this study was to compare the clinical results of arthroscopic partial meniscectomy of the knee between men and women with complex medial meniscal tear type while controlling for other variables that may affect outcome. This study compared groups of 86 men and 49 women who were followed prospectively using the Lysholm Knee Scoring Scale, the visual analogue scale, and patient's satisfaction. Mean age at operation was 51 years and mean follow-up was 26 months. Mean Lysholm score improved from 69 preoperatively to 82.1 postoperatively (P<.001) in the male group and from 64.2 preoperatively to 73.5 postoperatively (P=.04) in the female group. At last follow-up, 68 (79%) men and 35 (71%) women stated that they were satisfied with the operation. In both groups, the severity of chondral lesions was found to be negatively correlated to the preoperative score. Women had more severe chondral lesions at arthroscopy than men. This comparative study showed no significant difference between men and women in terms of clinical improvement following arthroscopic partial meniscectomies of complex tear types in stable knees with intact lateral meniscus. Women had lower functionality pre- and postoperatively, which correlated with more severe chondral degeneration at surgery compared with men.

Gender differences in the accuracy of joint line tenderness for arthroscopically confirmed meniscal tears.

INTRODUCTION: The reliability of joint line tenderness was previously investigated among other clinical tests for the diagnosis of meniscal pathology with variable results. The aim of this study was to evaluate and compare the accuracy of joint line tenderness as a clinical diagnosing test for arthroscopically confirmed meniscal tears between males and females. MATERIALS AND METHODS: For the purpose of preoperative joint line tenderness accuracy calculations, this study included male and female groups of patients who have had knee arthroscopy following preoperative diagnosis of meniscal tear. Overall, 195 patients were included in the study, 134 males and 61 females. The mean age was 43.4 (13-76) years. RESULTS: In the male group, the diagnosis of meniscal tear by joint line tenderness was correct in 84 (62.7%) of 134 knees for the medial side and in 115 (85.8%) for the lateral side. In the female group, the diagnosis was correct in 35 (57.4%) of 61 knees for the medial side and in 57 (93.4%) for the lateral side. In order to refine the accuracy of medial joint line tenderness, the data were recalculated for patients with medial meniscal tears and no chondral lesion or cruciate ligament tears; however, the accuracy remained low. CONCLUSIONS: The physical finding of joint line tenderness of the knee as a test for lateral meniscal tear was found reliable in both males and females. For medial meniscal tears, the test had low reliability and thus less useful if used alone, in both genders.

Extended Paratricipital Approach for Intra-articular Fractures of the Distal Humerus.

This article describes an extensile surgical exposure to the distal humerus that is suitable for complex fractures involving the articular surface and extending into the humeral diaphysis proximal to the radial nerve. This method combines 2 approaches: olecranon osteotomy and the lateral paratricipital approach. This combination allows an appropriate exposure of both the articular surface and the humeral diaphysis up to the level of the deltoid tuberosity, while maintaining the extensor mechanism unharmed.

A Novel Non-Invasive Adjuvant Biomechanical Treatment for Patients with Altered Rehabilitation after Total Knee Arthroplasty: Results of a Pilot Investigation.

BACKGROUND: Many factors contribute to suboptimal results after total knee arthroplasty (TKA) but little is known regarding the value of postsurgical rehabilitation after TKA. We examined the effects of an enhanced closed kinematic chain exercises program (AposTherapy) on gait patterns and clinical outcomes among patients with a lack of progress in their postsurgical rehabilitation. METHODS: Twenty-two patients were prospectively followed during the study. Gait spatiotemporal parameters were measured at the initial evaluation, after 15 minutes of therapy, and after 3 months of therapy. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the short form (SF) 36 health survey were completed by patients before treatment and after 3 months of treatment. RESULTS: The WOMAC and SF-36 scores improved significantly after 3 months of treatment. Gait velocity, single limb support, and step length of the operated leg improved significantly even after a single 15 minutes treatment. Normal gait velocity was observed in 36% of patients after 3 months of treatment. CONCLUSIONS: A physiotherapy program that included enhanced closed kinematic chain biomechanical therapy was beneficial for patients who experienced a suboptimal rehabilitation course after TKA.

Resection Arthroplasty for Resistant Ulcers Underlying the Hallux in Insensate Diabetics.

BACKGROUND: Foot ulcers carry considerable morbidity in patients with peripheral neuropathy and frequently lead to foot amputation. The purpose of this study was to present our experience treating recalcitrant ulcers underlying the hallux interphalangeal joint in patients with diabetes mellitus (DM)-related neuropathy with a first metatarsophalangeal (MTPJ1) resection arthroplasty. METHODS: We retrospectively reviewed the computerized medical files of patients with diabetic neuropathy treated with a MTPJ1 resection arthroplasty. We performed 28 arthroplasties on 20 patients with a mean age of 59 years. The patients had a diagnosis of DM for a mean of 10.7 years. Of the ulcers, 26 were grade 1A ulcers, and 2 were grade 2A ulcers (University of Texas score); the ulcer's mean age was 5.4 months. The mean dorsiflexion of the hallux before surgery was 46 degrees. RESULTS: The primary ulcer recovered in a mean of 3.1 weeks. Major complications (wound dehiscence and infection) occurred in 6 of 28 operations. Patients returned to normal activity 4 weeks after all procedures except in the 6 patients with dehiscence. In a subgroup of patients with follow-up longer than a year, the ulcer recurred after 4 of 18 arthroplasties (22%) between 3 and 12 months due to postoperative hallux rigidus. In the remaining 14 of 18 arthroplasties (78%), there was no recurrence during a mean follow-up of 26 months. CONCLUSION: MTPJ1 resection arthroplasty may be considered in a patient with resistant plantar hallux ulcerations, even in the absence of hallux rigidus. As with all operations on neuropathic feet in patients with DM, the surgeon and the patient should be aware that there is a significant likelihood of complications, but most are treatable.
