Type Of Fracture

Abstract Background: A Jones fracture is a transverse fracture of the V. metatarsal bone, without significant dislocation in the diaphysis junction and metaphyseal metaphysis. This type of fracture is usually associated with a minimal injury mechanism, and is characterized with minimal swelling, absence of hematoma and prolonged healing. The aim of the presented study was to compare the surgical and conservative therapy of Jones fracture. The study was registered in the www.clinicaltrials.gov database, under the ClinicalTrials.gov ID: NCT04037540 on 27th July 2019. Methods: A total of 27 study subjects were randomized into two groups – Conservative (K): 12, and Operational (O): 15. The study subjects were followed after 6 and 12 weeks using X-ray and the American Orthopedic Foot and Ankle Score (AOFAS). In the absence of X-ray signs of healing and low AOFAS score in Group K, treatment was considered unsuccessful and the patient was indicated for surgical treatment. Results: Five patients in Group K showed no signs of healing on X-ray after 12 to 6 weeks. These patients also manifested poor AOFAS scores and were indicated for surgical treatment and excluded from the study. Fracture failure was observed in seven patients. Their AOFAS scores were at the least satisfactory and, the patients continued in conservative therapy. After 12 weeks, 6 patients manifested fracture healing on X-ray and the AOFAS score of 100. In one patient who refused surgery, the fracture was not healed after 12 weeks. In Group O, seven patients achieved fracture healing on X-ray after 6 weeks, 8 patients did not show fracture healing. The average AOFAS score after 6 weeks was 97 (excellent). After 12 months, 13 patients showed findings of fracture healing on X-ray. The average AOFAS score was 100 points (maximum). Conclusions: The results of the study show that 1) Surgical treatment leads to significantly faster signs of healing on X-ray than the conservative one 2) After six weeks of surgery, 93% (14 out of 15) of patients are able to fully load the limb.

Background: Intramedullary screw fixation is a common method of treating proximal metadiaphyseal fifth metatarsal (ie, Jones) fractures. Fatigue failure is a complication of this fixation. There are many screw designs available, including Jones fracture specific fixation, but the optimal choice of screw design is unknown. The purpose of this study was to compare the fatigue strength of Jones fracture specific screw designs as well as other commonly used screw designs. Our hypothesis was that there would be no difference in fatigue strength for Jones fracture specific screw designs at similar screw diameters. Methods: A study was performed to determine the fatigue bending strength of 5 different screw designs including Jones fracture specific screw designs at 3 different screw diameters. Six screws of each size and design underwent cyclic fatigue testing, and a median fatigue limit (MFL) was determined for each screw design and size. Results: The Stryker Asnis JFX solid 4.0-mm, 5.0-mm, and 6.0-mm screws had a higher MFL than all other screws with similar diameter tested (all P < .0001). Both Jones fracture specific screw designs (Stryker Asnis JFX solid screws and Charlotte Carolina Jones screws) had higher MFLs than the other screw designs tested. Conclusion: This study provides comparative fatigue strength data on larger screw diameters, which have not been previously reported. There was a statistically significant difference in screw fatigue properties at the screw diameters tested. Clinical Relevance: The clinical significance of this study is that it provides surgeons with fatigue strength data to aid in screw selection for Jones fracture fixation.

Objectives: Jones fractures, which result in loss of playing time and subsequent dysfunction, remain a significant issue for elite contact athletes. The objectives of the present study are to (1) describe the epidemiology, surgical treatment, and impact on early National Football League (NFL) career of Jones fractures identified at the NFL Scouting Combine and (2) establish the value of computed tomography (CT) to determine healing following a Jones fracture in prospective NFL players. Methods: All players who attended the NFL Scouting Combine (2009-2015) were retrospectively reviewed to identify those who previously sustained a Jones fracture with position of play, treatment method, and number of missed collegiate games recorded. Overall mean draft pick, number of games started and played, snap percentage, and position-specific performance scores (Fantasy Score) were compared between Jones fracture athletes and controls without any major injury prior to the NFL Combine and during first three years of NFL career. A classification system, based on the grading of four individual quadrants (plantar, dorsal, medial, lateral), was applied by three orthopaedic surgeons. Results: Overall, the number of Jones fractures among athletes who attended the NFL Combine (2009-2015) was 72/2285 (3.2%) with all athletes treated via intramedullary (IM) screw fixation. Position-specific performance scores for players with a previous Jones fracture were lower than controls across all positions with a significant difference in running backs and defensive linemen. Subgroup CT scan analysis demonstrated a mean overall score of 2.5±1.3 with kappa values of 0.6 and 0.64 for inter- and intra-observer reliability, respectively. 16 Jones fractures (50%) were healed or nearly healed,12 (37.5%) were partially healed, and 4 (12.5%) showed little or no healing. The plantar cortex demonstrated least healing (56%), followed by the lateral cortex (46.9%). Conclusion: Although infrequent, Jones fractures are encountered at the NFL Combine with the highest prevalence at the tight end position and lowest at the running back position. Based on CT, 50% of all players with a previous Jones fracture demonstrate inhealing with least healing at the plantar and lateral cortices. Moreover, position-specific performance scores demonstrate worst performance at all positions for players with a previous Jones fracture versus controls.
