The Single-Person Lateral Decubitus Ankle Sling Fracture Reduction Technique

Ankle fractures are common pathologies encountered in the emergency department. Reduction of ankle fractures can be a challenging task to perform alone and can place medical personnel in mechanically disadvantageous positions. In addition, body weight and awkward lifting are leading preventable causes of musculoskeletal injuries among medical staff. The single-person lateral decubitus ankle sling fracture reduction method described is a simple and reproducible technique that utilizes the classic principles described by Dr Quigley in 1959. This technique optimizes patient positioning, utilizes gravity, and incorporates a stable ankle sling. This also incorporates a relaxed patient position to promote a successful ankle fracture reduction. Level of Evidence: Diagnostic Level IV.

A biomechanical comparison of the double-row suture fixation and compression screw techniques in the treatment of lateral malleolar avulsion fracture

BackgroundAvulsion fractures of fibula occur with ankle sprains. The purpose of this study was to compare the biomechanical characteristics of double-row suture versus compression screw techniques in treatment of lateral malleolar avulsion fracturelarger than 10 mm in size, which is typically not associated with an anterior talofibular ligament injury. MethodsWe simulated lateral malleolus avulsion fractures in six matched pairs of 12 human cadaveric ankles. These were then randomly divided into two groups: a double-row fixation group and a compression screw group. Biomechanical testing was performed after surgical fixation. The foot was rotated from the neutral position toward inversion at a rate of 1°/s until 12.5 N-m or structural failure was reached. The final rotation torque, rotation angle, stiffness, and displacement of the ossicles were recorded. ResultsNo significant difference was found in the final rotation torque (7.60 ± 3.70 vs 7.23 ± 2.06 N-m, p = 0.87), rotation angle (43.61 ± 14.77° vs 40.93 ± 10.94°, p = 0.56), stiffness (0.19 ± 0.08 vs 0.13 ± 0.07, p = 0.33), or displacement (6.11 ± 5.23 vs 7.09 ± 5.93 mm, p = 0.77) between the two groups. Conclusions: The stability of the double-row suture fixation was equivalent to compression screw fixation in treating a lateral malleolar avulsion fracture larger than 10 mm in size with ligament injury, as determined by our biomechanical testing.

Insights into orbital morphological features and fracture patterns in medial and inferior wall fracture: a retrospective cohort study

This study investigated the orbital morphological features that lead to fractures at different sites by comparing patients with isolated inferior wall fracture (IWF) to patients with isolated medial wall fracture (MWF). This study analyzed the orbital morphologic characteristics of all orbital fracture patients who underwent orbital computed tomography (CT) scans between January 2017 and October 2022. On CT scans, the bony structures of the orbit were measured. We investigated the bilateral symmetry of orbital. In addition, orbital morphological differences were compared between patients with fractures of the medial wall and those with fractures of the inferior wall. A total of 135 patients with orbital fractures were included in the study. Of these, 91 were isolated MWFs and 44 were isolated IWF. We confirmed the symmetry of bilateral orbits and measured the orbit of the uninjured side. No differences were found between the MWF group and the IWF group in terms of ocular prominence, horizontal orbital diameter, orbital rim angle, sagittal orbital depth, sagittal orbital depth, and angle of inferior wall inclination. The distance between the infraorbital nerve (ION) entry point and the orbital rim was significantly smaller in the inferior lateral wall fracture group than in the MWF group (11.87 ± 2.54 vs 14.90 ± 4.64, P < 0.001), and the percentage of type 1 ION was significantly lower in the IWF group than in the MWF group (40.9% vs 65.9%, P = 0.012). We demonstrated the symmetry of bilateral orbits and found that when the point where the ION enters the infraorbital canal is near the orbital rim, patients are more prone to suffering a fracture of the inferior wall after orbital trauma. It is less likely for patients with type 1 ION to suffer an IWF following an orbital fracture.

MUSCULOSKELETAL INJURIES FROM GENDER-BASED VIOLENCE AT A TERTIARY ORTHOPAEDIC CENTRE

Intimate partner violence (IPV) causes significant morbidity and its unlikely to be reported compared to other forms of gender-based violence (GBV). For early detection, understanding Orthopaedic injuries from GBV is vital. This study assesses the pattern of musculoskeletal injuries from GBV and determines the factors associated with it.It is a retrospective observational study of patients aged ≥18 years, with GBV-related acute Orthopaedic injuries. Data was reviewed from January 2021 to December 2021, including, demographic information, soft tissue and bony injuries, relationship to assailant, substance abuse and the day and time of injury. Frequencies and percentages for categorical data were analysed. Chi-square test was used to calculate association. T-test was used to compare groups for continuous &amp; categorical variables. Multivariate analysis was conducted to find the odds ratio and a p-value &lt;0.05 was statistically significant.138 patients were included, the mean age at presentation being 35.02 years (SD=11). 92.75% of GBV victims were females. Most were unemployed (66.7%). 30.43% (n-42) had a soft tissue injury; superficial laceration being the most common (23.1%), flexor tendon injury (10.87%), hand abscess (5.8%), and extensor tendon injury (5.07%). 71.02 % (n=98) sustained appendicular fractures. 51.45% (n=71) sustained upper limb fractures; distal radius fractures (10.86%) and distal 3rd ulnar fractures (9,42%). 19.57% (n=27) had lower limb fractures; 7.25% (n=10) had lateral malleolus ankle fractures. 63.7% (n=80) of cases were by an intimate partner on weekends (50.73%). 62.31% occurred between 16h00 and 0h00. 41.1% (n=65) reported alcohol abuse. 63.04% had surgery.GBV likely occurs in early middle-aged females by intimate partners influenced by alcohol over the weekends between 16h00 to 0h00. Distal radius/distal 3rd ulnar fractures are the most common bony injuries. Superficial wrist laceration is the commonest soft tissue injury. These findings may assist with early detection and intervention to prevent adverse outcomes in GBV.

Adjunctive fixation of the humeral epicondyle in a lateral condylar fracture model: Ex vivo comparison of pins and plates with a novel composite (AdhFix).

To compare the biomechanical properties of using a novel composite construct (AdhFix) to an interfragmentary Kirschner wire or a reconstruction plate as adjunctive epicondylar stabilization in simulated lateral unicondylar humeral fractures. Cadaveric biomechanical assessment. Paired humeri harvested from skeletally mature dogs (14-41 kg), nine cadavers per group. Simulated lateral unicondylar humeral fractures were stabilized with a transcondylar 4.5 mm cortical screw placed in lag fashion. Adjunct fixations consisting of a novel composite incorporating 2.7 mm cortical screws on one side, and either a 2.7 mm reconstruction plate or a 1.6 mm Kirschner wire on the contralateral side, were tested within paired humeri. Repaired humeri were axially loaded to failure and construct stiffness, yield load, and ultimate load were obtained from the load-deformation curves. In pairwise comparison, yield load was significantly higher for AdhFix group compared to the pin group, p = .016. No statistical significance was seen in the comparison between AdhFix group and the plate group, p = .25. Adhfix was mechanically superior to K-wires, and comparable to plate fixation, for adjunctive fixation in a lateral humeral condylar model. Our results support further investigation of the novel composite for adjunct fracture fixation in lateral humeral condylar fractures. The novel composite tested may be a viable alternative for adjunct fixation of humeral condylar fractures, a technique that circumvents plate contouring.

Complex Neck Loading and Injury Tolerance in Lateral Bending With Head Rotation From Human Cadaver Tests.

Advancements in automated vehicles may position the occupant in postures different from the current standard posture. It may affect human tolerance responses. The objective of this study was to determine the lateral bending tolerance of the head-cervical spine with initial head rotation posture using loads at the occipital condyles and lower neck and describe injuries. Using a custom loading device, head-cervical spine complexes from human cadavers were prepared with load cells at the ends. Lateral bending loads were applied to prerotated specimens at 1.5 m/s. At the occipital condyles, peak axial and antero-posterior and medial-lateral shear forces were: 316-954 N, 176-254 N, and 327-508 N, and coronal, sagittal, and axial moments were: 27-38 N·m, 21-38 N·m, and 9.7-19.8 N·m, respectively. At the lower neck, peak axial and shear forces were: 677-1004 N, 115-227 N, and 178-350 N, and coronal, sagittal, and axial moments were: 30-39 N·m, 7.6-21.3 N·m, and 5.7-13.4 N·m, respectively. Ipsilateral atlas lateral mass fractures occurred in four out of five specimens with varying joint diastasis and capsular ligament involvements. Acknowledging that the study used a small sample size, initial tolerances at the occipital condyles and lower neck were estimated using survival analysis. Injury patterns with posture variations are discussed.

Risk Factors for Failure of Nonsurgical Management of Ulnar Shaft Fractures

Isolated ulnar shaft fractures are frequently managed nonsurgically. However, rates of nonsurgical treatment failure remain substantial, and risk factors for the failure of nonsurgical management are not well described. This study investigated radiographic and patient-specific risk factors for the failure of nonsurgical management of isolated ulnar shaft fractures. A retrospective review of patients with ulnar shaft fractures initially treated nonsurgically was performed at two tertiary referral centers over a 19-year period from 2001 to 2020. Patient- and injury-related variables, surgical interventions, and plain radiographic measurements were recorded. The outcome of interest was failure of nonsurgical management, defined as failure to achieve fracture union nonsurgically within 3 months of injury. One hundred fifty four patients initially treated nonsurgically for isolated ulnar shaft fractures were included. Twenty six patients (17%) experienced failure of nonsurgical management; these included five nonunions, 16 delayed unions, and 10 conversions to surgical management. Patients who experienced failure of nonsurgical management had a higher prevalence of diabetes mellitus, a higher employment rate, and fractures with higher initial median posteroanterior and lateral translations, fracture gap, and angulation; 83% of the patients with an initial fracture gap of ≥4 mm and 41% of the patients with an initial fracture angulation of >10° failed nonsurgical management. Although most ulnar shaft fractures heal successfully with nonsurgical management, a substantial percentage of these fractures do not. Patients who are currently working, have diabetes mellitus, or have fractures with an initial fracture gap of ≥4 mm or an initial fracture angulation of > 10° may be more likely to fail nonsurgical treatment, although additional studies with larger sample sizes are needed to confirm these associations. Prognostic IV.

A Technical Tip to Treat the Intraoperative Lateral Cortex Fracture during a Medial Open-wedge High Tibial Osteotomy

Instability at the open-wedge osteotomy site due to disruption of the lateral cortex may contribute to displacement and may thus bring about delayed union or nonunion and recurrent varus deformity. Lateral cortex fracture in the medial open-wedge High Tibial Osteotomy (HTO) is an unstable situation, so surgeons can’t achieve primary stability on the osteotomy site easily. To our knowledge, despite being a feared complication, there are few reports dealing with the treatment for intraoperative lateral cortex fracture in the literatures. So, we present a case of intraoperative lateral cortex fracture during an open-wedge HTO and a simple technical tip to achieve primary stability. The use of Schanz pin on the tibial shaft is simple, improves the stability during fixation of plate and can be used to prevent the hinge dislocation during open-wedge HTO. But meticulous surgical procedures may help to decrease the incidence of unintentional lateral cortex fracture.

Relative lateral wall thickness is an improved predictor for postoperative lateral wall fracture after trochanteric femoral fracture osteosynthesis

Lateral wall thickness is a known predictor for postoperative stability of trochanteric femoral fractures and occurrence of secondary lateral wall fractures. Currently, the AO/OTA classification relies on the absolute lateral wall thickness (aLWT) to distinguish between stable A1.3 and unstable A2.1 fractures that does not take interpersonal patient differences into account. Thus, a more individualized and accurate measure would be favorable. Therefore, we proposed and validated a new patient-specific measure—the relative lateral wall thickness (rLWT)—to consider individualized measures and hypothesized its higher sensitivity and specificity compared with aLWT. First, in 146 pelvic radiographs of patients without a trochanteric femoral fracture, the symmetry of both caput-collum-diaphyseal angle (CCD) and total trochanteric thickness (TTT) was assessed to determine whether the contralateral side can be used for rLWT determination. Then, data of 202 patients were re-evaluated to compare rLWT versus previously published aLWT. Bilateral symmetry was found for both CCD and TTT (p ≥ 0.827), implying that bone morphology and geometry of the contralateral intact side could be used to calculate rLWT. Validation revealed increased accuracy of the rLWT compared with the gold standard aLWT, with increased specificity by 3.5% (Number Needed to Treat = 64 patients) and sensitivity by 1% (Number Needed to Treat = 75 patients). The novel rLWT is a more accurate and individualized predictor of secondary lateral wall fractures compared with the standard aLWT. This study established the threshold of 50.5% rLWT as a reference value for predicting fracture stability in trochanteric femoral fractures.

Fracture intensity and associated variability: A new methodology for 3D digital outcrop model analysis of carbonate reservoirs

The presence of hydraulically conductive fracture networks fundamentally affects subsurface fluid flow, the recovery factor and productivity in hydrocarbon carbonate reservoirs. However, methods to directly detect and map the 3D distribution and intensity of fracture networks in the subsurface is difficult. We present a new workflow and methodologies to overcome these limitations utilizing 3D digital photogrammetry on a prominent outcrop of the Late Jurassic (Kimmeridgian) Jubaila Formation near Wadi Laban (Riyadh, Saudi Arabia) as an example. Subsurface equivalents of the Upper Jubaila Formation host major oil and gas accumulations on the Arabian platform. The workflow includes mapping of fracture intensity, distribution and orientation along a 750 m long exposure transect using a high-resolution 3D Digital Outcrop Model (DOM). Results show two main fracture trends, which were E-W and NNE-SSW oriented. The techniques enable computation of fracture intensity directly on the 3D DOM, and quantification of lateral and vertical fracture intensity variability and fracture corridors. The new methodology of 3D DOM analysis, provides a reliable characterization of fractures and fracture intensity that are critical for enhancing 3D reservoir models.

The PFNA in treatment of intertrochanteric fractures with or without lateral wall fracture in elderly patients: a retrospective cohort study

BackgroundThere is no consensus about intertrochanteric fractures with lateral wall treated with intramedullary nail—proximal femoral nail antirotation (PFNA). The aim of the present study was to compare function outcomes between lateral wall and no lateral wall fractures after surgery by PFNA.MethodsThis retrospective study evaluated patients with or without lateral wall fractures who underwent PFNA between January 2015 and June 2018. The operative time, intraoperative blood loss, time to fracture healing, complications and functional outcomes qualified by Harris hip score and Parker − Palmer mobility score (PPMS) were compared between the two groups.ResultsTwo groups were comparable with regard to patient age, sexual distribution, mechanism of injury, fracture type, body mass index (BMI), Time to surgery, American Society of Anesthesiologists (ASA) score and quality of reduction. The incomplete group had a longer operation time (54.1 ± 8.74 min vs. 51.0 ± 9.86 min) and more intraoperative blood loss (228.4 ± 48.8 ml vs. 151.3 ± 43.5 ml) in comparison with the control group (P < 0.01). Regarding functional outcome, the HHSs of the two groups were 76.2 ± 11.6 vs 75.6 ± 12.5 at the 3 months (P = 0.603), 81.9 ± 9.4 vs 82.6 ± 8.7 at the six months (P = 0.224), 83.8 ± 6.6 vs 84.5 ± 6.0 at the twelve months 85.2 ± 5.5 vs 86.0 ± 5.8 at the twenty-four months (P > 0.05), respectively. Similar results were obtained about PPMS. We found no difference in Weight bearing time, Time of fracture healing, and Complications between incomplete group and intact group.ConclusionsThere is no substantial difference in functional results or complication rates for intertrochanteric fractures with lateral wall fractures, except from increased blood loss and operation time. We believe that an intramedullary nail will be sufficient to repair an intertrochanteric fracture with or without a lateral wall fracture.

Effect of hollow compression screw internal fixation in treating McCrory-Bladin type Ⅱ lateral process fracture of the talus: open versus arthroscopy surgery

In order to explore the clinical efficacy of hollow compression screw internal fixation in the treatment of lateral process fracture of the talus under open surgery versus arthroscopy procedure, a retrospective cohort study was conducted to analyze the clinical data of 33 patients with lateral process fracture of the talus admitted to Xuzhou Central Hospital from January 2019 to December 2021. There were 19 males (19 feet) and 14 females (14 feet), aged 18 to 50 years, with an average age of (32.2±9.3) years. According to the modified McCrory-Bladin classification, all patients were classified as type Ⅱ. Based on the different surgical methods, the patients were divided into the arthroscopy group (21 cases, treated with double-tunnel subtalar arthroscopy combined with hollow compression screw internal fixation) and the open group (12 cases, treated with open reduction and internal fixation with hollow compression screw). The operation time was observed and the surgical effects were evaluated using the visual analogue scale (VAS) of pain, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the Foot Function Index (FFI), and the Foot and Ankle Ability Measure (FAAM), which includes the FAAM-ADL (activity of daily living subscale) and the FAAM-S (sport subscale). All the patients of the two groups achieved stage Ⅰ wound healing. On the first day after the operation, the mean VAS score of the arthroscopy group was 2.4±0.7, which was significantly lower than that of the open group (3.4±1.6) (P=0.020). No significant difference was observed in terms of the follow-up time, operation time and AOFAS score between the two groups (all P>0.05). The FFI score of the arthroscopy group was significantly lower than that of the open group, and the FAAM-ADL and FAAM-S scores were significantly higher than those in the open group (all P<0.05). Two cases of dorsal foot numbness occurred in the open group after the operation, and the incidence of complications was not significantly different from that of the arthroscopy group (P=0.054). For McCrory-Bladin type Ⅱ lateral process fracture of the talus, the use of compression screw internal fixation could achieve reliable results, however, compared to open surgery, arthroscopy procedure obtained mini trauma and better functions.

Clinical Analysis of the Frosch Approach in the Treatment of Posterolateral Tibial Plateau Fractures Combined with Lateral Tibial Plateau Fractures.

The treatment of posterolateral tibial plateau fractures is difficult, and providing sufficient exposure and effective fixation is a challenge. There is great controversy regarding the surgical approach for posterolateral tibial plateau fractures. The purpose of the study was to investigate the clinical effects of open reduction and internal fixation using the Frosch approach for the treatment of posterolateral tibial plateau fractures combined with lateral tibial plateau fractures. Data from 19 patients with posterolateral tibial plateau fractures combined with lateral tibial plateau fractures treated from May 2018 to January 2022 were retrospectively analyzed. There were nine men and 10 women, ranging in age from 22 to 62 years, with an average age of 45.6 years. All patients were treated using the Frosch approach. Under direct vision, the posterolateral and lateral fractures were reduced, and full bone grafting was performed. We reshaped the oblique "T" shaped plate for the distal radius and placed it on the posterolateral tibial plateau to fix the posterolateral fractures. The lateral inverted "L" shaped locking plate was placed on the lateral tibial plateau to fix the lateral tibial plateau fractures. Within 2 weeks after the operation, the patients were instructed to perform knee joint function exercises within 90°. At the last follow-up, the Rasmussen radiological criteria were used to evaluate the effectiveness of fracture reduction and fixation. And the knee joint function was evaluated using Rasmussen functional score. The operation time ranged from 100 to 180 min, with an average of 134.2 min; intraoperative blood loss ranged from 20 to 150 mL, with an average of 66.8 mL. The follow-up duration ranged from 14 to 58 months, with an average of 36.2 months. There were no complications, such as vascular or nerve injury or incision infection. Fracture healing was achieved in all patients, and the healing time ranged from 10 to 14 weeks, with an average of 11.2 weeks. During the follow-up period, there was no loosening or breakage of the internal fixation, varus or valgus deformity of the knee joint, re-collapse of the articular surface, or instability of the knee joint. At the last follow-up, the effectiveness of fracture reduction and fixation was excellent in 13 patients and good in six patients. And the knee joint function was excellent in 17 patients and good in two patients. The Frosch approach for open reduction and internal fixation in the treatment of posterolateral tibial plateau fractures combined with lateral tibial plateau fractures has a definite clinical benefit and is worthy of promotion and application.

Incidence and risk factors for lateral hinge fractures in medial opening wedge high tibial osteotomy and medial opening wedge distal tibial tuberosity osteotomy

BackgroundThe aims of this study were (1) to compare the incidence of lateral hinge fractures (LHFs) in medial opening-wedge high tibial osteotomy (OWHTO) and medial opening-wedge distal tibial tuberosity osteotomy (DTO), and (2) to investigate the risk factors for LHFs. The incidence of LHFs was hypothesized to be higher in the DTO group than the OWHTO group. The DTO procedure is also a risk factor for LHFs. MethodsA total of 167 knees that underwent OWHTO (n = 65) and DTO (n = 102) were subjected to propensity score matching for the comparison of the groups. The matched variables were sex, preoperative hip-knee-ankle (HKA) angle, and preoperative medial proximal tibial angle. Forty-one matched pairs were enrolled for comparative analysis. Logistic regression analysis was performed to investigate risk factors for LHFs. ResultsThe incidence of LHFs was not significantly different between the groups (34.1% vs. 26.8%, respectively; p = 0.631). Logistic regression analysis showed that age (odds ratio: 1.074, 95% confidence interval (CI): 1.020–1.131, p = 0.007), BMI (odds ratio: 1.150, 95% CI: 1.049–1.260, p = 0.003), and preoperative HKA angle (odds ratio: 1.150, 95% CI: 1.049–1.260, p = 0.035) were significant risk factors for LHFs. The difference in surgical technique between OWHTO and DTO was not a risk factor for LHFs (p = 0.204). ConclusionsThe incidence of LHFs is similar in DTOs and OWHTOs, and the DTO procedure is not a risk factor for LHFs.Level of Evidence: Level III, retrospective cohort study.

Prospective randomized controlled trial: early weight bearing after conservative treatment of Weber B ankle fractures (pancake trial)

PurposeDifferent studies have shown that weightbearing is safe in stable transsyndesmotic, isolated lateral simple ankle fractures. Despite this evidence, AO guidelines still recommend immobilization with above-the-knee cast for 4–6 weeks for these fractures. The objective of this study was to compare the outcomes of mobilization and weightbearing to those of immobilization and non-weightbearing in patients with stable transsyndesmotic, lateral isolated simple ankle fractures.MethodsFifty patients were randomly assigned to permissive weightbearing in a walking boot or non-weightbearing immobilization using a below-the-knee cast. Primary outcome was ankle functionality as scored by the Olerud-Molander Ankle Score (OMAS). Secondary outcomes were radiological displacement of fracture, range of motion (ROM), calf circumference, and RAND 36-item health survey. Patients were in follow-up for 24 months.ResultsAnkle functionality after six and twelve weeks was significantly higher for the intervention group, with respectively 30 points (p = 0.001) and 10 points (p = 0.015) of difference. ROM improved significantly in the intervention group after six weeks. All fractures showed radiological progression of fracture healing. RAND 36-item showed differences in both physical (60.3 vs. 46.3, p = 0.017) and mental (78.5 vs. 58.2, p = 0.034) components in favor of the intervention group. In 16% of patients who initially showed stable fractures on radiographic imaging, joint dislocation was identified on weightbearing radiographs prior to randomization, leading to exclusion.ConclusionWeightbearing and mobilization using a walking boot may be a safe treatment for patients with stable Weber B fractures.

Intramedullary Fibular Strut Allograft and a Small Fragment Nonlocking T-plate for Periprosthetic Lateral Femoral Condyle Fracture: A Case Report

Treatment of Hoffa fracture of femoral condyle with anchor combined with auxiliary fixation.

A Hoffa fracture is an unstable intra-articular break that is generally treated with surgery. To evaluate the feasibility and clinical outcomes of using a suture anchor combined with auxiliary fixation for the treatment of a lateral femoral condyle Hoffa fracture. The study retrospectively reviewed 8 patients (5 males and 3 females) with a lateral femoral condyle Hoffa fracture who had been treated by combining a suture anchor with auxiliary fixation between January 2016 and April 2020. The mean age of patients was 37.5 years (ranging from 23 to 45). According to Letenneur's classification, there were 4 cases of type I, 2 cases of type II, and 2 cases of type III fractures. The clinical outcomes were assessed using Letenneur's functional assessment. The follow-up duration ranged between 14-24 months. All patients achieved primary healing of the incision and fracture union, as well as normal flexion and extension of the knee joint, with 7 cases showing excellent outcomes and 1 case showing a good outcome. No postoperative complications, such as fracture displacement, anchor loosening, or fracture malunion, occurred in this series. Our results indicated that a suture anchor, combined with external fixation, was an effective treatment for a lateral femoral condyle Hoffa fracture. Accordingly, this procedure is worthy of wider clinical application.

Orif of lateral Hoffa's fracture with irreducible patella dislocation and incarcerated patella in lateral Hoffa's fragment: rare injury presentation

Majority of lateral Hoffa fracture are associated with knee injury. Presenting a case of 30-years-old gentleman who presented with pain, swelling, deformity in knee of right side after road traffic accident. On local examination there was marked swelling with inability to palpate patella, inability to flex knee. On clinical examination, there was patella dislocation as it was not in place and unable to reduce. Radiological investigation showed a lateral Hoffa's fracture with dislocation of patella and patella being incarcerated in Hoffa fragment. Operative and follow up: Patient was operated by open reduction of patella dislocation and CC screw fixation for lateral Hoffa fracture. On six weeks follow up normal ROM achieved. Patient was surgically treated to relocate locked patella fragment in Hoffa's fragment and fix Hoffa's fragment and achieved good range of motion.
